ABSTRACT

Objetivo: Validar la técnica de ganglio centinela utilizando verde de indocianina en la estadificación del cáncer de endometrio. Método: Realizamos un estudio prospectivo entre enero y diciembre de 2021. Se incluyeron todas las pacientes portadoras de cáncer de endometrio clínicamente en etapa 1, de todos los grados de diferenciación e histologías. Todas las pacientes fueron sometidas a una estadificación laparoscópica. Se inició el procedimiento con identificación de ganglio centinela utilizando verde de indocianina. Posteriormente, se completó la cirugía de estadiaje estándar en todas las pacientes. Los ganglios centinelas fueron procesados con técnica de ultraestadiaje. Resultados: Se incluyeron 33 pacientes. El 81% presentaron histología endometrioide. El 100% fueron sometida además a una linfadenectomía pelviana estándar y el 20% a una linfadenectomía paraaórtica simultáneamente. Se detectó al menos un ganglio centinela en el 100% de los casos. La detección bilateral ocurrió en el 90,9%. La localización más frecuente fue la fosa obturatriz y la arteria hipogástrica. Obtuvimos una sensibilidad del 90% para detectar enfermedad ganglionar y un valor predictivo negativo del 95,8%. Conclusiones: La técnica de ganglio centinela utilizando verde de indocianina es replicable. Los resultados de nuestra serie nos permiten realizar procedimientos menos agresivos al estadificar el cáncer de endometrio.


Objective: To validate sentinel node mapping using indocyanine green in endometrial cancer staging. Method: A prospective study was conducted between January and December 2021. All patients with clinically stage 1 endometrial cancer, of all grades and histologies were included. All patients underwent laparoscopic staging. The procedure began with identification of the sentinel node using indocyanine green. Subsequently, standard staging surgery was completed in all patients. Sentinel nodes were processed using ultrastaging technique. Results: Thirty-three patients were enrolled. 81% of cases had endometrioid histology. All patients also underwent a standard pelvic lymphadenectomy and in 20% of cases a para-aortic lymphadenectomy. At least one sentinel node was detected in 100% of the cases. Bilateral detection occurred in 90.9%. The most frequent location was obturator fossa and hypogastric artery. Sensitivity to detect lymph node disease was 90% and negative predictive value 95.8%. Conclusions: Sentinel lymph node mapping using indocyanine green is a replicable technique. Our results allows us to perform less aggressive procedures in endometrial cancer staging.

ABSTRACT

Corded and hyalinized endometrioid carcinoma (CHEC) is a morphologic variant of endo-metrioid adenocarcinoma. The tumor exhibits a biphasic appearance with areas of traditional low-grade adenocarcinoma merging directly with areas of diffuse growth composed of epithelioid or spindled tumor cells forming cords, small clusters, or dispersed single cells. It is crucial to distinguish CHEC from its morphological mimics, such as malignant mixed mullerian tumor (MMMT), because CHECs are usually low stage, and are associated with a good post-hysterectomy prognosis in most cases while the latter portends a poor prognosis. The patient reported in this article was a 54-year-old woman who presented with postmenopausal vaginal bleeding for 2 months. The ultrasound image showed a thickened uneven echo endometrium of approximately 12.2 mm and a detectable blood flow signal. Magnetic resonance imaging revealed an abnormal endometrial signal, considered endometrial carcinoma (Stage Ⅰ B). On hysterectomy specimen, there was an exophytic mass in the uterine cavity with myometrium infiltrating. Microscopically, most component of the tumor was well to moderately differentiated endometrioid carcinoma. Some oval and spindle stromal cells proliferated on the superficial surface of the tumor with a bundle or sheet like growth pattern. In the endometrial curettage specimen, the proliferation of these stromal cells was more obvious, and some of the surrounding stroma was hyalinized and chondromyxoid, which made the stromal cells form a cord-like arrangement. Immunostains were done and both the endometrioid carcinoma and the proliferating stroma cells showed loss of expression of DNA mismatch repair protein MLH1/PMS2 and wild-type p53 protein. Molecular testing demonstrated that this patient had a microsatellite unstable (MSI) endometrial carcinoma. The patient was followed up for 6 months, and there was no recurrence. We diagnosed this case as CHEC, a variant of endometrioid carcinoma, although this case did not show specific β-catenin nuclear expression that was reported in previous researches. The striking low-grade biphasic appearance without TP53 mutation confirmed by immunohistochemistry and molecular testing supported the diagnosis of CHEC. This special morphology, which is usually distributed in the superficial part of the tumor, may result in differences between curettage and surgical specimens. Recent studies have documented an aggressive clinical course in a significant proportion of cases. More cases are needed to establish the clinical behaviors, pathologic features, and molecular profiles of CHECs. Recognition of the relevant characteristics is the prerequisite for pathologists to make correct diagnoses and acquire comprehensive interpretation.

ABSTRACT

Objective: To investigate the differences in molecular classification of endometrial carcinoma (EC) between various technical methods and to explore molecular classification schemes suitable for Chinese population. Methods: The study used a comprehensive scheme of next generation sequencing (NGS) and immunohistochemistry for molecular classification of 254 EC cases that were obtained at Department of Pathology, Obstetrics and Gynecology Hospital of Fudan University, Shanghai, China from April 2021 to March 2022. According to the recommended threshold of Sanger sequencing which was approximate-20% variant allele fraction (VAF), NGS data were extracted to simulate the results of Sanger sequencing. Results: The 254 EC patients had a mean age of 51 years (range, 24 to 89 years). Combination of POLE (9-14 exons), TP53 total exons and microsatellite instability (MSI) detection was a better single scheme than NGS alone, while combination of MSI fragment analysis and conventional immunohistochemistry was the best solution and seemed best aligned with TCGA data and recent studies. POLE ultramuted type, mismatch repair defect type, TP53 mutant type and non-specific molecular characteristic type accounted for 11.4% (29/254), 31.5% (80/254), 22.4% (57/254) and 34.6% (88/254) of the cases, respectively. If Sanger sequencing was adopted for POLE and TP53 detection, the frequencies of these EC types were 9.1% (23/254), 31.5% (80/254), 12.9% (33/254) and 46.6% (118/254), respectively, with greatly increasing non-specific molecular characteristics cases. If POLE was detected by Sanger sequencing and others by immunohistochemistry, they were 9.1% (23/254), 42.2% (92/218), 13.8% (35/254) and 40.9% (105/254), respectively, with increasing the false positive rates of the mismatch repair defect group. Conclusions: Small and medium-sized NGS panels with MSI detection is a better solution than NGS alone. Sanger sequencing is currently available for POLE mutation detection, which is not sensitive enough for TP53 mutation detection, and seems equivalent to the efficiency of TP53 by immunohistochemistry. Further optimization of small and medium-sized NGS panels covering MSI detection and POLE and TP53 full exons may be the best choice for the future to meet national conditions.

ABSTRACT

Objective: To compare the prognosis and perioperative situation of patients with stage Ⅱ endometrial cancer (EC) between radical hysterectomy/modified radical hysterectomy (RH/mRH) and simple hysterectomy (SH). Methods: A total of 47 patients diagnosed EC with stage Ⅱ [International Federation of Gynecology and Obstetrics (FIGO) 2009] by postoperative pathology, from January 2006 to January 2021 in Peking University People's Hospital, were analyzed retrospectively. The patients were (54.4±10.7) years old, and the median follow-up time was 65 months (ranged 9-138 months). They were divided into RH/mRH group (n=14) and SH group (n=33) according to the scope of operation. Then the prognosis of patients between the groups were compared, and the independent prognostic factors of stage Ⅱ EC were explored. Results: (1) The proportions of patients with hypertension in RH/mRH group and SH group were 2/14 and 45% (15/33), the amounts of intraoperative blood loss were (702±392) and (438±298) ml, and the incidence of postoperative complications were 7/14 and 15% (5/33), respectively. There were significant differences (all P<0.05). (2) The median follow-up time of RH/mRH group and SH group were 72 vs 62 months, respectively (P=0.515). According to Kaplan-Meier analysis and log-rank method, the results showed that there were no significant difference in 5-year progression-free survival (PFS) rate (94.3% vs 84.0%; P=0.501), and 5-year overall survival rate (92.3% vs 92.9%; P=0.957) between the two groups. Cox survival analysis indicated that age, pathological type, serum cancer antigen 125 (CA125), and estrogen receptor (ER) status were associated with 5-year PFS rate (all P<0.05). But the scope of hysterectomy (RH/mRH and SH) did not affect the 5-year PFS rate of stage Ⅱ EC patients (P=0.508). And level of serum CA125 and ER status were independent prognostic factors for 5-year PFS rate (all P<0.05). Conclusions: This study could not find any survival benefit from RH/mRH for stage Ⅱ EC, but increases the incidence of postoperative complications. Therefore, the necessity of extending the scope of hysterectomy is questionable.

ABSTRACT

Objective: To explore the effects of preoperative hysteroscopic guided biopsy and segmental diagnosis and curettage on the risk of abdominal dissemination and prognosis of non-endometrioid carcinoma. Methods: The clinical and pathological data of 97 patients who underwent surgical treatment and were pathologically confirmed as non-endometrioid carcinoma (including serous carcinoma, clear cell carcinoma, mixed adenocarcinoma, and undifferentiated carcinoma, etc.) from October 2008 to December 2021 in Peking University People's Hospital, were collected for retrospective analysis. According to preoperative diagnostic methods, they were divided into hysteroscopic group (n=44) and non-hysteroscopic group (n=53). The impact of hysteroscopy examination on peritoneal cytology and prognosis was analyzed. Results: (1) There were no statistical differences in age, body mass index, tumor size, pathological characteristics, and treatment methods between the hysteroscopic group and the non-hysteroscopic group (all P>0.05), but the proportion of stage Ⅰ-Ⅱ patients in the hysteroscopic group was significantly higher than that in the non-hysteroscopic group [68% (30/44) vs 47% (25/53); χ2=4.32, P=0.038]. (2) Among 97 patients, 25 (26%, 25/97) of them were cytologically positive for ascites. The hysteroscopic group had a lower positive rate of peritoneal cytology than that in the non-hysteroscopy group, which was significantly different [11% (5/44) vs 38% (20/53); χ2=8.74, P=0.003]. Stratification according to surgical and pathological stages showed that the positive rate of peritoneal cytology in the hysteroscopic group (3%, 1/30) was lower than that in the non-hysteroscopic group (12%, 3/25) in the 55 patients with stage Ⅰ-Ⅱ, and that in the hysteroscopic group (4/14) was also lower than that in the non-hysteroscopic group (61%, 17/28) in the 42 patients with stage Ⅲ-Ⅳ. There were no significant differences (all P>0.05). (3) The 5-year disease-free survival (DFS) rate of the hysteroscopic group and the non-hysteroscopic group were respectively 72.7% and 60.4%, and there was no significant difference between the two groups (P=0.186). After stratification according to staging, the 5-year DFS rate were respectively 90.0% and 72.0% (P=0.051) between the hysteroscopic and non-hysteroscopic groups of patients in stage Ⅰ-Ⅱ, and 35.7% and 50.0% (P=0.218) between the hysteroscopic and non-hysteroscopic groups of patients in stage Ⅲ-Ⅳ, in which there were not statistically significant differences. The 5-year overall survival (OS) rate were respectively 86.4% and 81.1% between the hysteroscopic group and the non-hysteroscopic group, with no significant difference between the two groups (P=0.388). The 5-year OS rate were respectively 93.3% and 96.0% in the hysteroscopic group and non-hysteroscopic group for patients with stage Ⅰ-Ⅱ(P=0.872), and 71.4% and 67.9% in the hysteroscopic group and non-hysteroscopic group in patients with stage Ⅲ-Ⅳ (P=0.999), with no statistical significance. Conclusions: Diagnostic hysteroscopy do not increase the rate of positive peritoneal cytology result at the time of surgery in this cohort, and no significant correlation between preoperative hysteroscopy examination and poor prognosis of non-endometrioid carcinoma is observed. Therefore, preoperative hysteroscopic guided biopsy and segmental diagnosis and curettage in non-endometrioid carcinoma maybe safe.

ABSTRACT

Objective: To explore the concordance and causes of different mismatch repair (MMR) and microsatellite instability (MSI) detection results in endometrial carcinoma (EC) molecular typing. Methods: A total of 214 EC patients diagnosed from January 2021 to April 2023 were selected at the Department of Pathology, Peking University Third Hospital. The immunohistochemistry (IHC) results of MMR protein were reviewed. Tumor specific somatic mutations, MMR germline mutations, microsatellite scores and tumor mutation burden (TMB) were detected by next-generation sequencing (NGS) with multi-gene panel. Methylation-specific PCR was used to detect the methylation status of MLH1 gene promoter in cases with deficient MLH1 protein expression. In cases with discrepant results between MMR-IHC and MSI-NGS, the MSI status was detected again by PCR (MSI-PCR), and the molecular typing was determined by combining the results of TMB and MLH1 gene promoter methylation. Results: (1) In this study, there were 22 cases of POLE gene mutation subtype, 55 cases of mismatch repair deficient (MMR-d) subtype, 29 cases of p53 abnormal subtype, and 108 cases of no specific molecular profile (NSMP). The median age at diagnosis of MMR-d subtype (54 years old) and the proportion of aggressive histological types (40.0%, 22/55) were higher than those of NSMP subtype [50 years old and 12.0% (13/108) respectively; all P<0.05]. (2) Among 214 patients, MMR-IHC test showed that 153 patients were mismatch repair proficient (MMR-p), 49 patients were MMR-d, and 12 patients were difficult to evaluate directly. MSI-NGS showed that 164 patients were microsatellite stable (MSS; equal to MMR-p), 48 patients were high microsatellite instability (MSI-H; equal to MMR-d), and 2 patients had no MSI-NGS results because the effective sequencing depth did not meet the quality control. The overall concordance between MMR-IHC and MSI-NGS was 94.3% (200/212). All the 12 discrepant cases were MMR-d or subclonal loss of MMR protein by IHC, but MSS by NGS. Among them, 10 cases were loss or subclonal loss of MLH1 and (or) PMS2 protein. Three discrepant cases were classified as POLE gene mutation subtype. In the remaining 9 cases, 5 cases and 3 cases were confirmed as MSI-H and low microsatellite instability (MSI-L) respectively by MSI-PCR, 6 cases were detected as MLH1 gene promoter methylation and 7 cases demonstrated high TMB (>10 mutations/Mb). These 9 cases were classified as MMR-d EC. (3) Lynch syndrome was diagnosed in 27.3% (15/55) of all 55 MMR-d EC cases, and the TMB of EC with MSH2 and (or) MSH6 protein loss or associated with Lynch syndrome [(71.0±26.2) and (71.5±20.1) mutations/Mb respectively] were significantly higher than those of EC with MLH1 and (or) PMS2 loss or sporadic MMR-d EC [(38.2±19.1) and (41.9±24.3) mutations/Mb respectively, all P<0.01]. The top 10 most frequently mutated genes in MMR-d EC were PTEN (85.5%, 47/55), ARID1A (80.0%, 44/55), PIK3CA (69.1%, 38/55), KMT2B (60.0%, 33/55), CTCF (45.5%, 25/55), RNF43 (40.0%, 22/55), KRAS (36.4%, 20/55), CREBBP (34.5%, 19/55), LRP1B (32.7%, 18/55) and BRCA2 (32.7%, 18/55). Concurrent PTEN, ARID1A and PIK3CA gene mutations were found in 50.9% (28/55) of MMR-d EC patients. Conclusions: The concordance of MMR-IHC and MSI-NGS in EC is relatively high.The discordance in a few MMR-d EC are mostly found in cases with MLH1 and (or) PMS2 protein loss or MMR protein subclonal staining caused by MLH1 gene promoter hypermethylation. In order to provide accurate molecular typing for EC patients, MLH1 gene methylation, MSI-PCR, MMR gene germline mutation and TMB should be combined to comprehensively evaluate MMR and MSI status.

ABSTRACT

Objective: To investigate the impact of molecular classification and key oncogenes on the oncologic outcomes in patients with endometrial carcinoma (EC) and atypical endometrial hyperplasia (AEH) receiving fertility-preserving treatment. Methods: Patients with EC and AEH undergoing progestin-based fertility-preserving treatment and receiving molecular classification as well as key oncogenes test at Obstetrics and Gynecology Hospital, Fudan University from January 2021 to March 2023 were reviewed. Hysteroscopic lesion resection and endometrial biopsy were performed before initiating hormone therapy and every 3 months during the treatment to evaluate the efficacy. The risk factors which had impact on the treatment outcomes in EC and AEH patients were further analyzed. Results: Of the 171 patients analyzed, the median age was 32 years, including 86 patients with EC and 85 patients with AEH. The distribution of molecular classification was as follows: 157 cases (91.8%) were classified as having no specific molecular profile (NSMP); 9 cases (5.3%), mismatch repair deficient (MMR-d); 3 cases (1.8%), POLE-mutated; 2 cases (1.2%), p53 abnormal. No difference was found in the cumulative 40-week complete response (CR) rate between the patients having NSMP or MMR-d (61.6% vs 60.0%; P=0.593), while the patients having MMR-d had increased risk than those having NSMP to have recurrence after CR (50.0% vs 14.4%; P=0.005). Multi-variant analysis showed PTEN gene multi-loci mutation (HR=0.413, 95%CI: 0.259-0.658; P<0.001) and PIK3CA gene mutation (HR=0.499, 95%CI: 0.310-0.804; P=0.004) were associated with a lower cumulative 40-week CR rate, and progestin-insensitivity (HR=3.825, 95%CI: 1.570-9.317; P=0.003) and MMR-d (HR=9.014, 95%CI: 1.734-46.873; P=0.009) were independent risk factors of recurrence in EC and AEH patients. Conclusions: No difference in cumulative 40-week CR rate is found in the patients having NSMP or MMR-d who received progestin-based fertility-preserving treatment, where the use of hysteroscopy during the treatment might be the reason, while those having MMR-d have a higher risk of recurrence after CR. Oncogene mutation of PTEN or PIK3CA gene might be associated with a lower response to progestin treatment. The molecular profiles help predict the fertility-preserving treatment outcomes in EC and AEH patients.

ABSTRACT

Objective: To investigate the relationships between molecular types of the cancer genome atlas (TCGA) of patients with endometrial carcinoma (EC) and lymph node metastasis and other clinicopathological features. Methods: The clinical pathological information of 295 patients with EC who underwent initial inpatient surgical treatment and accepted the detection of the molecular types of TCGA with next-generation sequencing technology at Peking University People's Hospital were collected during April 2016 and May 2022. The TCGA molecular typing of EC was divided into four types: POLE-ultramutated (15 cases), high microsatellite instability (MSI-H; 50 cases), copy-number low (CNL; 175 cases), and copy-number high (CNH; 55 cases). The differences of clinical pathological features among different molecular types and the risk factors of lymph node metastasis were analyzed retrospectively. Results: Among 295 patients with EC, the average age was (56.9±0.6) years. (1) There was a statistically significant difference in lymph node metastasis (0, 8.0%, 10.3% and 25.5%) among the four molecular types (χ2=12.524, P=0.006). There were significant differences in age, stage, pathological type, grade (only endometrioid carcinoma), myometrium invasion, lymphatic vascular space infiltration, and estrogen receptor among the EC patients of four molecular types (all P<0.05). Among them, while in the patients with CNH type, the pathological grade was G3, the pathological type was non-endometrioid carcinoma, and the proportion of myographic infiltration depth ≥1/2 were higher (all P<0.05). (2) Univariate analysis suggested that pathological type, grade, myometrium infiltration depth, cervical interstitial infiltration, lymphatic vascular space infiltration, and progesterone receptor were all factors which significantly influence lymph node metastasis (all P<0.01); multivariate analysis suggested that the lymphatic vascular space infiltration was an independent risk factor for lymph node metastasis (OR=5.884, 95%CI: 1.633-21.211; P=0.007). (3) The factors related to lymph node metastasis were different in patients with different molecular types. In the patients with MSI-H, the non-endometrioid carcinoma of pathological type was independent risk factor for lymph node metastasis (OR=29.010, 95%CI: 2.067-407.173; P=0.012). In the patients with CNL, myometrium infiltration depth≥1/2 (OR=4.995, 95%CI: 1.225-20.376; P=0.025), lymphatic vascular space infiltration (OR=14.577, 95%CI: 3.603-58.968; P<0.001) were the independent risk factors for lymph node metastasis. While in the CNH type patients pathological type of non-endometrioid carcinoma (OR=7.451, 95%CI: 1.127-49.281; P=0.037), cervical interstitial infiltration (OR=22.938, 95%CI: 1.207-436.012; P=0.037), lymphatic vascular space infiltration (OR=9.404, 95%CI: 1.609-54.969; P=0.013), were the independent risk factors for lymph node metastasis. Conclusions: POLE-ultramutated EC patients have the lowest risk of lymph node metastasis, and CNH patients have the highest risk of lymph node metastasis. The risk factors of lymph node metastasis of different molecular types are different. According to preoperative pathological and imaging data, lymph node metastasis is more likely to occur in patients with non-endometrioid carcinoma in MSI-H and CNH type patients, and lymph node metastasis is more likely to occur in patients with myometrium infiltration depth ≥1/2 in CNL type patients.

ABSTRACT

Abstract Objective To evaluate the presence of residual disease in the uterine specimen after hysteroscopic polypectomy or polyp biopsy in patients with endometrioid endometrial cancer (EC). Methods We analyzed a series of 104 patients (92 cases from the Hospital AC Camargo and 12 from the Hospital do Servidor Público Estadual de São Paulo) with polyps that were diagnosed by hysteroscopy, showing endometrioid EC associated with the polyp or in the final pathological specimen. Patients underwent a surgical approach for endometrial cancer from January 2002 to January 2017. Their clinical and pathological data were retrospectively retrieved from the medical records. Results In78cases (75%), thepolyphad EC, and in 40(38.5%), itwas restricted tothe polyp, without endometrial involvement. The pathologic stage was IA in 96 cases (92.3%) and 90 (86.5%) had histologic grade 1 or 2. In 18 cases (17.3%), there was no residual disease in the final uterine specimen, but only in 9 of them the hysteroscopy suggested that the tumor was restricted to the polyp. In 5 cases (4.8%) from the group without outside of the polyp during hysteroscopy, myometrial invasion was noted in the final uterine specimen. This finding suggests the possibility of disease extrapolation through the base of the polyp. Conclusion Patients with endometrioid EC associated with polyps may have the tumor completely removed during hysteroscopy, but the variables shown in the present study could not safely predict which patient would have no residual disease.


Resumo Objetivo Avaliar a presença de doença residual no exame anatomopatológico definitivo de pacientes com câncer de endométrio endometrioide após polipectomia ou biópsia de pólipo histeroscópica. Métodos Analisamos 104 pacientes (92 casos do Hospital AC Camargo e 12 casos do Hospital do Servidor Público Estadual de São Paulo) com pólipos diagnosticados durante histeroscopia e cuja biópsia histeroscópica ou exame patológico final do útero acusaram câncer de endométrio endometrioide. As pacientes foram submetidas a cirurgia para câncer de endométrio de janeiro de 2002 a janeiro de 2017. Os dados clínicos e anatomopatológicos de cada paciente foram retirados dos prontuários médicos Resultados Em 78 casos (75%), o pólipo continha a neoplasia, e em 40 (38.5%), ela estava restrita ao tecido do pólipo, sem envolvimento endometrial adjacente. O estadio final foi IA em 96 casos (92.3%) e em 90 (86.5%) tratava-se de grau 1 ou 2. Em 18 casos (17.3%), não havia doença residual no espécime uterino, mas emapenas 9 deles a histeroscopia sugeriu doença restrita ao pólipo. Em 5 casos (4.8%), não havia doença aparente extrapólipo na histeroscopia, mas havia invasão miometrial, sugerindo extravasamento do tumor pela base do pólipo. Conclusão Pacientes com câncer de endométrio associado a pólipos podem ter o tumor completamente removido durante a histeroscopia, mas, com as variáveis avaliadas, é difícil predizer com segurança qual paciente ficará sem tumor residual.

ABSTRACT

Abstract Objective The aim of the present study was to analyze relapse rates and patterns in patients with endometrial cancer with the aim of evaluating the effectiveness of current follow-up procedures in terms of patient survival, as well as the convenience of modifying the surveillance strategy. Methods Retrospective descriptive study including all patients diagnosed with endometrial cancer relapse at the Department of Gynecology and Obstetrics of the Complejo Hospitalario Insular-Materno Infantil de Canarias, between 2005 and 2014. Results Recurrence was observed in 81 patients (10.04% of the sample); 66.7% of them suffered relapse within 2 years and 80.2% within 3 years after the termination of the primary treatment; 41.9% showed distant metastases while the rest corresponded to local-regional (40.7%) or ganglionar (17.4%) relapse; 42% of these were symptomatic; 14 patients showed more than 1 site of relapse. Relapse was detected mainly through symptoms and physical examination findings (54.3%), followed by elevated serummarker levels (29.6%), computed tomography (CT) images (9.9%) and abnormal vaginal cytology findings (6.2%). No differences in global survival were found between patients with symptomatic or asymptomatic relapse. Conclusion Taking into account that the recurrence rate of endometrial cancer is low, that relapse occurs mainly within the first 3 years post-treatment and that symptom evaluation and physical examination are the most effective follow-up methods, we postulate that a modification of the current model of hospital follow-up should be considered.

ABSTRACT

BACKGROUND@#Endometrial cancer (EC) has been one of the most general cancers with respect to gynecological malignancies; however, there are debates on clinical strategies concerning treatments especially for patients with grade 3 (G3) endometroid endometrial cancer (EEC). Present study aimed to evaluate the lymphatic metastasis (LM) related factors and figure out the necessity of lymphadenectomy for G3 EEC patients.@*METHODS@#From January 2009 to April 2019, 3751 EC patients were admitted to Obstetrics and Gynecology Hospital of Fudan University. Clinical characteristics include age, grade, stage, and clinical pathological features. A total of 1235 EEC patients were involved in the multivariable analysis. Three hundred and eighty-one patients were involved in the survival analysis and the data attributed to sufficient follow-up information. Kaplan-Meier curve and log-rank test were utilized to analyze the survival rate.@*RESULTS@#Among the 1235 EEC patients, 181 (14.7%) were categorized as G3 and 1054 (85.3%) were grade 1 to grade 2 (G1-2). Multivariate analysis demonstrated that lymphovascular space invasion, adnexal involvement, and cervical stroma involvement were independent risk factors of LM in G3 cohort with odds ratio 3.4, 5.8, and 8.9; 95% confidence interval 1.1-10.6, 1.5-22.4, and 2.8-28.0, respectively. LM rates increased from 3.3% (3/92) to 75% (9/12) for G3 EEC cohort as related factor numbers increased from one to three. There were no differences between G3 and G1-2 EEC in overall survival and progression free survival. Additionally, no survival advantage was observed for G3 EEC patients at early stage with different plans of adjuvant treatment.@*CONCLUSIONS@#For G3 EEC patients without other pathological positive factor, the LM rate is lower than those with other pathological positive factor. Survival analysis showed no difference between G3 cohort and G1-2 cohort. Also, different adjuvant treatments had no impact on the overall survival for G3 EEC patients.

ABSTRACT

Abstract Objective To evaluate the agreement between the histopathological diagnoses of preoperative endometrial samples and surgical specimens and correlate the agreement between the diagnoses with the impact on surgical management and the survival of patients with endometrial adenocarcinomas. Methods Sixty-two patients treated for endometrial cancer at a university hospital from 2002 to 2011 were retrospectively evaluated. The histopathological findings of preoperative endometrial samples and of surgical specimens were analyzed. The patients were subjected to hysterectomy as well as adjuvant treatment, if necessary, and clinical follow-up, according to the institutional protocol. Lesions were classified as endometrioid tumor (type 1) grades 1, 2, or 3 or non-endometrioid carcinoma (type 2). Results The agreement between the histopathological diagnoses based on preoperative endometrial samples and surgical specimens was fair (Kappa: 0.40; p < 0.001). However, the agreement was very significant for tumor type and grade, in which a higher concordance occurred at a higher grade. The percentage of patients with lymph nodes affected was 19.2%;. Although most patients presenting with disease remission or cure were in the early stages (90.5%;), there were no significant differences between those patients who had a misdiagnosis (11/16; 68.8%;) and those who had a correct diagnosis (25/33; 75.8%;) based on preoperative endometrial sampling (p = 0.605). Conclusion Our findings corroborate the literature and confirm the under staging of preoperative endometrial samples based on histopathological assessment, especially for lower grade endometrial tumors. We suggest that the preoperative diagnosis should be complemented with other methods to better plan the surgical management strategy.


Resumo Objetivo Avaliar a concordância entre os diagnósticos histopatológicos de amostras endometriais pré-operatórias e cirúrgicas de pacientes com adenocarcinomas endometriais e avaliar o impacto da concordância entre os diagnósticos no planejamento cirúrgico e sobrevida das pacientes. Métodos Dados de 62 pacientes com câncer de endométrio operadas entre 2002 a 2011 em um hospital universitário foram avaliadas retrospectivamente. As pacientes foram submetidas à histerectomia e tratamento adjuvante, se necessário, e acompanhadas clinicamente de acordo com o protocolo institucional. Foram avaliados os resultados das análises histopatológicas das amostras endometriais pré-operatórias e cirúrgicas. As lesões foram classificadas como tumor endometrioide (tipo 1) graus 1, 2 ou 3 ou carcinoma não endometrioide (tipo 2). Resultados De modo geral, houve uma concordância baixa entre os diagnósticos histopatológicos das amostras endometriais pré-operatórias e cirúrgicas (Kappa: 0,40; p < 0,001). Entretanto, uma alta concordância entre os diagnósticos foi observada nos tumores de graus mais elevados. Comprometimento de linfonodos ocorreu em 19,2%; das pacientes e a maioria das que apresentaram remissão ou cura foram diagnosticadas nos estágios iniciais da doença (90,5%;). Não houve diferença significativa na taxa de remissão ou cura entre as pacientes que tiveram concordância (25/33; 75,8%;) ou divergência (11/16; 68,8%;) entre os resultados histopatológicos pré-operatórios e cirúrgicos (p = 0,605). Conclusão Nossos achados corroboram a literatura e confirmam o sub-estadiamento de amostras endometriais pré-operatórias com base na avaliação histopatológica, especialmente para tumores endometriais de baixo grau. Outros métodos complementares são necessários para um diagnóstico pré-operatório mais preciso a fim de melhorar o planejamento cirúrgico.

ABSTRACT

ANTECEDENTES: existe una asociación demostrada entre endometriosis y algunas histologías del carcinoma epitelial de ovario. Por otra parte, se ha observado que hasta un 30% de las neoplasias de ovario se presentan de forma concomitante a neoplasias del endometrio. Para considerar la sincronicidad entre estos tumores, estos deben cumplir criterios anatomopatológicos estrictos como los descritos por scully. OBJETIVO: presentar un caso clínico de carcinoma endometrioide sincrónico de ovario y endometrio sobre focos de endometriosis, así como su diagnóstico y manejo. CASO CLÍNICO: paciente de 27 años que consulta por spotting intermenstrual. En la ecografía endocavitaria se observa un pólipo endometrial. Además, se describe un tumor anexial izquierdo de 42mm, trilobulado, con un polo sólido de 17×15mm. Se somete a una polipectomía histeroscópica y quistectomía ovárica laparoscópica. Asimismo, se reseca implante sospechoso en el fondo de saco posterior. El resultado anatomopatológico de las piezas quirúrgicas fue: pólipo endometrial con hiperplasia compleja con atipias y focos de adenocarcinoma endometrioide grado I; el tumor quístico ovárico izquierdo consistente con quiste endometriósico con focos de adenocarcinoma endometrioide. La lesión peritoneal corresponde a un implante de adenocarcinoma endometrioide grado I. El estudio de las características anatomopatológicas y la presencia del implante peritoneal sugieren el diagnóstico de un carcinoma endometrioide ovárico con origen en una lesión endometriósica sincrónico con un carcinoma endometrioide endometrial. CONCLUSIÓN: el diagnóstico diferencial entre la sincronicidad o diseminación de los tumores de ovario y endometrio de estirpe endometrioide supone un reto para el clínico y es fundamental para el correcto manejo de estas neoplasias.


BACKGROUND: there is a demonstrated association between endometriosis and some epithelial ovarian carcinoma histologies. On the other hand, it has been observed that up to 30% of ovarian neoplasms present concomitantly with endometrial neoplasms. To consider synchronicity between these neoplasms, they must meet strict pathological criteria such as those described by scully. OBJECTIVE: to introduce a case of an ovarian and endometrial synchronous endometrioid carcinoma implanted on endometriosis sites, as well as its diagnosis and management. CLINICAL CASE: a 27-year-old patient who consulted because of an intermenstrual spotting. The ultrasound image showed an endometrial polyp. Furthermore, a 42 mm left adnexal trilobal tumor with a 17×15mm solid pole was described. She underwent a hysteroscopic polypectomy and laparoscopic ovarian cystectomy. Likewise, resection of a suspicious implant in the posterior vaginal fornix was done. The pathological result of the surgical pieces was: endometrial polyp with complex hyperplasia with atypia and focal points of grade I endometrioid adenocarcinoma; the left ovarian cystectomy: endometriotic cyst with focal points of endometrioid adenocarcinoma. The peritoneal lesion corresponded to a grade I endometrioid adenocarcinoma implant. The study of the pathological characteristics and the presence of the peritoneal implant suggest the diagnosis of endometrioid ovarian carcinoma originated in a synchronous endometriotic lesion with endometrial endometrioid carcinoma. CONCLUSION: differential diagnosis between the synchronicity or spread of ovarian and endometrial endometrioid cell line carcinomas, is a great challenge and it is essential for the correct management of these neoplasms

ABSTRACT

INTRODUCCIÓN: el carcinoma endometrial es la sexta entidad maligna más común a nivel mundial. En la mayoría de casos se diagnóstica de forma temprana. Recurre principalmente a cúpula vaginal y a nivel linfático, sin embargo, se han descrito metástasis a vagina, peritoneo y pulmones, entre otros. PRESENTACIÓN DEL CASO: paciente femenina adulta mayor con antecedente de carcinoma endometrial hace 7 años, tratado quirúrgicamente con estudio histopatológico que evidenciaba un miometrio infiltrado en un 95% sin invasión a otros órganos y linfadenectomía libre de lesión (estadio FIGO IB), quien consulta por dolor abdominal localizado en mesogastrio y deposiciones melénicas, evidenciándose una lesión gástrica, con resultado de biopsia que reporta carcinoma pobremente diferenciado con positividad focal para vimentina compatible con metástasis gástrica secundaria a carcinoma endometrial. Se indica manejo sistémico con quimioterapia, se documenta respuesta total de la lesión. DISCUSIÓN: las lesiones tumorales a nivel de estómago son primarios en su gran mayoría, una metástasis a este nivel es inusual. En el momento del diagnóstico de una metástasis gástrica, la mitad de las pacientes presentan concomitante compromiso de otros órganos. El carcinoma endometrial no está descrito dentro de los primarios que generan este compromiso. CONCLUSIÓN: el caso expuesto es un reto clínico, que representa un vacío en la evidencia actual; se comparte la experiencia de un manejo exitoso. Son necesarios más estudios para evaluar el pronóstico, opciones de tratamiento y definir la pertinencia de métodos de tamización para la detección temprana de estos casos.


INTRODUCTION: the endometrial carcinoma is the sixth cancer worldwide. Usually it is diagnosed in early stages. The sites of recurrence includes vaginal cuff and lymph nodes, however some metastasis have been described to vagina, peritoneum and lungs, among others. CASE REPORT: Elder female with history of an endometrial carcinoma 7 years ago, surgically treated. With histopathology that reported myometrial infiltration in a 95% without invasion to other organs and lymphadenectomy free of neoplasm (FIGO IB), who consult at the emergency room due to abdominal pain and black stool, with further studies that make evident a gastric lesion with biopsy reported as a poorly differentiated carcinoma, vimentin positive, compatible with gastric metastasis secondary to an endometrial carcinoma. Chemoterapy was indicated, documenting total posterior response of the lesion. DISCUSSION: Secondary lessions in stomach are rare. If they are present at the moment of diagnosis half of the patients concomitantly have metastasis in other organs. The endometrial carcinoma hasn't been described as a common localization that result in this compromise. CONCLUSION: the case exposed is a clinical challenge, a therapeutic success is shared. Limited evidence is available. Further studies are necessary to evaluate the prognosis, therapeutic options and to define the relevance of screening tests for early detection.

ABSTRACT

Abstract Background Most endometrial cancers (75%) are diagnosed in early stages (stages I and II), in which abnormal uterine bleeding is the most frequent clinical sign.When the diagnosis is performed in stage IV, the most common sites of metastasis are the lungs, liver and bones. Central nervous system (CNS)metastasis is a rare condition. The aim of this study is to describe a case of uterine papillary serous adenocarcinoma of the endometrium that progressed to brain and bone metastases. Case Report We present the case of a 56-year-old woman with abnormal uterine bleeding and endometrial thickened echo (1.8 cm). A hysteroscopy with biopsy was performed, which identified poor differentiated serous adenocarcinoma of the endometrium. A total abdominal hysterectomy, with pelvic and para-aortic lymphadenectomy, was performed. Analysis of the surgical specimen revealed a grade III uterine papillary serous adenocarcinoma. Adjuvant radio/chemotherapy (carboplatin and paclitaxel-six cycles) was indicated. Sixteen months after the surgery, the patient began to complain of headaches. Brain magnetic resonance imaging demonstrated an expansile mass in the right parietal lobe, suggesting a secondary hematogenous implant subsequently confirmed by biopsy. She underwent surgery for treatment of brain metastasis, followed by radiotherapy. She died 12 months after the brain metastasis diagnosis due to disease progression. Conclusion Uterine papillary serous adenocarcinoma of the endometrium has a low propensity to metastasize to the brain. To the best of our knowledge, this is the fifth documented case of uterine papillary serous adenocarcinoma of the endometrium with metastasis to the CNS.


Resumo Fundamentos A maioria dos cânceres de endométrio (75%) é diagnosticada em estágios iniciais (estágios I e II), nos quais o sangramento uterino anormal é o sinalclínico mais frequente. Quando o diagnóstico é realizado no estágio IV, os locais mais comuns de metástase são os pulmões, o fígado e os ossos. A metástase para o sistema nervoso central (SNC) é uma condição rara. O objetivo deste estudo é descrever um caso de adenocarcinoma seroso-papilífero do endométrio que progrediu para metástases cerebral e óssea. Relato de Caso Apresentamos o caso de uma mulher de 56 anos com sangramento uterino anormal e eco endometrial espessado (1,8 cm). Foi realizada histeroscopia com biópsia que identificou adenocarcinoma seroso-papilífero pouco diferenciado do endométrio. Uma histerectomia abdominal total, com linfadenectomia pélvica e para-aórtica, foi realizada. A análise da peça cirúrgica revelou adenocarcinoma seroso-papilífero do endométrio grau III. Radioterapia adjuvante/quimioterapia (carboplatina e paclitaxel- seis ciclos) foi indicada.Dezesseismeses após a cirurgia, a paciente começou a se queixar de dores de cabeça. A ressonância magnética cerebral demonstrou uma massa expansiva no lobo parietal direito, sugerindo um implante hematogênico secundário posteriormente confirmado por biópsia. A paciente foi submetida a cirurgia para tratamento de metástase cerebral, seguida de radioterapia. A paciente morreu 12 meses após o diagnóstico de metástase cerebral devido à progressão da doença. Conclusão O adenocarcinoma seroso-papilífero do endométrio tem uma baixa propensão a metastizar para o cérebro. Até onde sabemos, este é o quinto caso documentado de adenocacinoma seroso-papilífero do endométrio com metástase para o SNC.

ABSTRACT

El carcinoma de endometrio es la neoplasia más frecuente del tracto genital de la mujer en el mundo occidental es una patología que va en ascenso en los países en vías de desarrollo. En general, el pronóstico de carcinoma endometrial es bueno, con una supervivencia global de alrededor del 80 %. Se pueden definir tres grupos de acuerdo al riesgo de recurrencia, en alto, medio y bajo. Se realiza revisión bibliográfica y casuística para proponer protocolo de manejo quirúrgico en pacientes con cáncer de endometrio. Se definen tres etapas durante el protocolo: clínica, patológica y quirúrgica. Se realizan recomendaciones basados en la vía de abordaje, tipo de histerectomía, lavado peritoneal, linfadenectomía, omentectomía, y cito-reducción. Se plantean situaciones especiales y la importancia del ganglio centinela. La realización de protocolos quirúrgicos para el manejo de carcinoma endometrial permite la unificación de criterios, mejora la evaluación de respuesta rapéutica y facilita revisiones y mejoras a futuro.(AU)


The endometrial carcinoma is the most common neoplasia in the genital tract of women in the western world and is a condition that is increasing in the developing countries. In general, the rognosis of endometrial carcinoma is good, with an overall survival of about 80 %. It can define three groups according to the risk of the recurrence in high, medium and low. The literature review and case mix is performed to propose the surgical management protocol in patients with endometrial cancer. Three stage the clinical, the pathological and the surgical defined for the protocol. The recommendations based on the approach, type of the ysterectomy, te peritoneal washing, the lymphadenectomy, the omentectomy, and the debulking are made. The special situations and the importance of sentinel node arise. Performing the surgical protocol for the management of endometrial carcinoma allows the unification of criteria, the improved therapeutic response assessment and facilitates future revisions and improvements.(AU)

ABSTRACT

Conocer los indicadores de salud, como una forma de evaluar calidad del servicio que una institución presta a la población. La incidencia, prevalencia y tasas de mortalidad, son tres elementos básicos a conocer, esto permite planificar priorizar las necesidades de una determinada población, mejorando la optimización de recursos y conocer en que eslabón de la historia natural de la enfermedad se puede actuar. Queremos determinar la incidencia registrada en nuestro servicio, desde el 2000 hasta el 2015, de cada una de las patologías malignas atendidas. Un total de 1 824 historias de un universo de 4 911; las restantes no pudieron ser revisadas, por su desincorporación del archivo activo. Apreciamos que la patología con mayor incidencia fue el cáncer de cuello uterino, con un pequeño orcentaje (10 %) iagnosticado en estadio I. Seguidamente encontramos al cáncer de endometrio representando un 12 % de los casos. Dentro de la patología de ovario, el carcinoma epitelial representó el 75 %. El carcinoma de trompa de Falopio solo el 0,3 % de todas las patologías malignas del área inecológica, similar a lo eportado en la literatura mundial. Igualmente el cáncer de vulva, vagina y sarcoma uterino, representaron un escaso porcentaje de incidencia. Este trabajo constituye una fase inicial de investigaciones futuras, en las cuales se deben calcular tasas de upervivencia y período libre de enfermedad, además de incentivar la actualización anual, para evitar sub-registro por la pérdida de datos.(AU)


To know health indicators, is a way to assess the quality of service an institution provides to the population. The incidence, the prevalence and the mortality rates are three basic known elements, which allow you to plan and prioritize the needs of a given population, the improving resource optimization and know that link the natural history of the disease can act. With our research we want to determine the impact registered in our department from the year 2000 to the year 2015, each of the malignant athologies treated. A total of 1 824 stories of a universe of 4 911 were reviewed; the other could not be reviewed by the divestiture of the active file. However, with the data analyzed appreciate that the disease was highest incidence was the cervical cancer, with a small percentage (8 %) diagnosed with stage I, and then found the endometrial cancer representing 12 % of cases. Within pathology ovarian epithelial carcinoma he represented the most frequent with 75 %. The Fallopian tube carcinoma represented only 0.3 % of all malignant gynecological pathologies area, similar to that reported in the literature. Likewise cancer of the vulva, the vagina and the uterine sarcoma, accounted for a small percentage of incidences. This paper is an initial phase of future investigations, which must be calculated survival rates and the disease-free period, in addition to encouraging the annual update, to avoid underreporting by data loss.(AU)

ABSTRACT

OBJECTIVE@#To determine the effect of metformin and adiponectin on the proliferation of EC cells and the relationship between metformin and adiponectin.@*METHODS@#The proliferation impact of different concentrations of metformin and adiponectin on two types of EC cells ishikawa (IK) and HEC-1B was confirmed by CCK-8 method. qRT-PCR and Western blot were used to detect the effect of different concentrations of metformin on the changes of adiponectin receptors (AdipoR1 and AdipoR2) of the EC cells both in mRNA and protein level and the role of compound C, an adenosine monophosphate-activated protein kinase (AMPK) inhibitor, on the above effects.@*RESULTS@#(1) Both metformin and adiponectin could significantly promote the proliferation of endometrial cancer (EC) cells in a time and concentration dependent manner (P<0.05).(2)Metformin and adiponectin had synergy anti-proliferative effect on EC cells and the combination index (CI) value of IK cells was 0.906 34 and of HEC-1B cells was 0.827 65. (3)qRT-PCR was used to detect the mRNA levels of AdipoR1 and AdipoR2 after 5 mmol/L and 10 mmol/L metformin, respectively, stimulating IK and HEC-1B cells for 48 hours and the mRNA expressions of AdipoR1 and AdipoR2 were significantly increased when compared with the control group (0 mmol/L)(IK: AdipoR1 of 5 mmol/L and 10 mmol/L group: P<0.001,AdipoR2 of 5 mmol/L group: P<0.001; HEC-1B: AdipoR1 of 5 mmol/L group: P<0.001, 10 mmol/L group: P=0.023, AdipoR2 of 5 mmol/L group: P<0.001, 10 mmol/L group: P=0.024). When combined with compound C, the RNA levels of AdipoR1 and AdipoR2 were not different compared with the control group (0 mmol/L, P>0.05). (4) Western blot was used to detect the protein levels of AdipoR1 and AdipoR2 after 5 mmol/L and 10 mmol/L metformin, stimulating IK and HEC-1B cells for 48 hours and the protein level was significantly increased when compared with the control group (0 mmol/L)(IK: AdipoR1 of 5 mmol/L group: P=0.04, 10 mmol/L group: P=0.033, AdipoR2 of 5 mmol/L group: P=0.044, 10 mmol/L group: P=0.046; HEC-1B: AdipoR1 of 5 mmol/L group: P=0.04, 10 mmol/L group: P=0.049, AdipoR2 of 5 mmol/L group: P=0.043, 10 mmol/L group: P=0.035). When combined with compound C,the protein levels of AdipoR1 and AdipoR2 were not different compared with the control group (0 mmol/L, P>0.05).@*CONCLUSION@#We find that metformin and adiponectin have synergy anti-proliferative effect on EC cells. Besides, metformin can increase adiponectin receptors expressions of EC cells both in mRNA and protein levels and this effect is accomplished by the activation of AMPK signaling pathway.

ABSTRACT

Propofol is an intravenous sedative hypnotic agent of which the growth-inhibitory effect has been reported on various cancers. However, the roles of propofol in endometrial cancer (EC) remain unclear. This study aimed to explore the effects of propofol on EC in vitro and in vivo. Different concentrations of propofol were used to treat Ishikawa cells. Colony number, cell viability, cell cycle, apoptosis, migration, and invasion were analyzed by colony formation, MTT, flow cytometry, and Transwell assays. In addition, the pcDNA3.1-Sox4 and Sox4 siRNA plasmids were transfected into Ishikawa cells to explore the relationship between propofol and Sox4 in EC cell proliferation. Tumor weight in vivo was measured by xenograft tumor model assay. Protein levels of cell cycle-related factors, apoptosis-related factors, matrix metalloproteinases 9 (MMP9), matrix metalloproteinases 2 (MMP2) and Wnt/β-catenin pathway were examined by western blot. Results showed that propofol significantly decreased colony numbers, inhibited cell viability, migration, and invasion but promoted apoptosis in a dose-dependent manner in Ishikawa cells. Moreover, propofol reduced the expression of Sox4 in a dose-dependent manner. Additionally, propofol significantly suppressed the proportions of Ki67+ cells, but Sox4 overexpression reversed the results. Furthermore, in vivo assay results showed that propofol inhibited tumor growth; however, the inhibitory effect was abolished by Sox4 overexpression. Moreover, propofol inhibited Sox4 expression via inactivation of Wnt/β-catenin signal pathway. Our study demonstrated that propofol inhibited cell proliferation, migration, and invasion but promoted apoptosis by regulation of Sox4 in EC cells. These findings might indicate a novel treatment strategy for EC.

ABSTRACT

RESUMEN El cáncer sincrónico endometrial y ovárico (SEOC) representa alrededor de un 5-10% de las neoplasias de endometrio y ovario. Cuando no existe extensión locorregional y presentan un patrón histológico de bajo grado, actúan como si fueran dos tumores primarios independientes, en lugar de comportarse como un cáncer en estadio avanzado. Los mecanismos para diferenciar si su origen es metastásico o por el contrario, son tumores primarios independientes conlleva una gran dificultad y ha generado una importante controversia dentro del estudio de este tipo de neoplasias. En este artículo, exponemos el caso clínico de una paciente de 46 años que presenta un tumor sincrónico de endometrio y ovario en estadio IA, desconocido hasta el estudio histológico de la pieza quirúrgica.


ABSTRACT Endometrial and ovarian synchronous cancer (SEOC) accounts for about 5-10% of endometrial and ovarian neoplasms. When there is no local extension and they present a low-grade histological pattern, they act as if they were two independent primary tumours, instead of behaving as an advanced stage cancer. Therefore, the differentiation of its origin (metastatic or independent primary tumours) is fraught with difficulty and has generated a significant controversy in the study of this type of neoplasms.
