ABSTRACT

Introdução: O carcinoma endometrial (CE) foi classificado pelo sistema de Bokhman em tipos I e II com base em observações clínicas e epidemiológicas. O tipo I corresponde aos tumores de baixo grau e o tipo II aos tumores de alto grau. Adicionalmente, estudos recentes propuseram que a classificação também fosse baseada em aspectos histológicos e moleculares com base nos dados do TCGA (The Cancer Genome Atlas). Foram identificados quatro grupos moleculares distintos de CE: (1) com mutações no POLE (fenótipo "ultramutado"), (2) "alto número de cópias" (mutações em TP53), (3) !baixo número de cópias" (em que os tumores não apresentam nenhuma das alterações descritas nos outros tipos) e (4) tumores com predomínio de instabilidade de microssatélites. A imunohistoquímica (IHC) para proteínas do gene de reparo é usada para identificar a deficiência de genes de reparo do DNA (Mismatch Repair ­ MMR) associada à instabilidade de microssatélites(MSI). A coloração nuclear positiva representa a expressão retida de proteínas MMR, enquanto a perda completa representa deficiência de MMR. O padrão de expressão heterogênea (HEP), ou seja, concomitância em um mesmo espécime de áreas positivas e totalmente negativas tem sido observada em CE. No presente momento, as principais diretrizes determinam que a presença de HEP seja interpretada como expressão retida de proteínas MMR. Não há, porém, consenso quanto à classificação e interpretação de HEP, nem conhecimento do impacto da classificação de HEP como subtipo molecular diferente em relação às características clínicas e prognósticas. Objetivos: realizar a classificação molecular dos casos de CE com HEP das proteínas relacionadas aos genes de reparo do DNA e comparação do perfil molecular entre áreas positivas e negativas no estudo imunohistoquímico. Materiais e Métodos: De janeiro/2007 a dezembro/2017 foram identificados 356 casos de CE, 16 deles com HEP. A classificação molecular foi feita com base no protocolo PROMISE para CE. Cada área (expressão retida ou perdida) foi macrodissecada e o status molecular foi avaliado separadamente quanto ao status MSI (Idylla), metilação do promotor MLH1 (NGS - ponto de corte para positividade ≥ 15%), status POLE (NGS) e status p53 (IHC). Variáveis clínicas e patológicas também foram avaliadas e correlacionadas com cada caso. Resultados: A histologia endometrioide foi predominante (15 casos), bem como ausência de invasão linfovascular (11 casos), ausência de padrão MELF (10 casos), graus FIGO 1 e 2 (13 casos), invasão miometrial < 50% (13 casos) e estadiamento T1 (13 casos). Todos os pacientes estavam vivos e sem evidência de doença no último acompanhamento, exceto por um caso, cujo status de sobrevida era desconhecido. Dois casos que seriam descritos como apresentando expressão retida de proteínas relacionadas a genes de reparo do DNA por IHC apresentaram-se na análise molecular com instabilidade de microssatélites(MSI-H). Nos casos de HEP, a proteína MSH6 foi a maisfrequentemente envolvida (9 casos, 7 isolados). A proteína MLH1 apresentou-se alterada em 6 casos, sendo a única proteína associada a co-alterações (com MSH6 e PMS2). Seis casos apresentaram-se metilados por MLH1, padrão encontrado tanto em áreas com perda quanto em áreas com retenção das proteínas relacionadas a MMR por IHC e dois casos apresentaram metilação em apenas uma das áreas. Em relação ao status de POLE, 6 casos apresentaram mutação, 2 com mutações tanto em áreas com perda quanto em áreas com retenção de expressão, 3 apenas na área com perda e 1 apenas na área com retenção. Dois casos apresentam padrão aberrante de p53 (MSH6 alterados) em ambas as áreas. Conclusão: em pacientes portadoras CE e com tumores apresentando HEP a correlação entre a IHC e os achados moleculares é heterogênea e o diagnóstico entre casos com retenção ou das proteínas relacionadas a MMR não é factível apenas com realização de IHC. A análise molecular deve ser realizada em todos os casos de CE com HEP para determinar adequadamente as característicasintrínsecas de cada tumor. Devido à raridade desse achado, esta proposta é financeiramente viável e tem o potencial de mudar a prática clínica em um subconjunto de pacientes, permitindo tratamentos inovadores. HEP deve ser relatado como um padrão distinto e não considerado como uma expressão sinônimo de expressão retida de proteínas MMR em CE.


Introduction: Endometrial adenocarcinoma is classified by the Bokhman system in type I and II based on clinical and epidemiological observations, whereas the type I represents low grade tumors and type II high grade tumors. Additionally, a classification based on histological aspects and molecular profile has been proposed. The TCGA (The Cancer Genome Atlas) identified four molecular groups of endometrial adenocarcinomas: (1) mutations in POLE ("ultramutated" phenotype), (2) "high copy number" (mutations in TP53), (3) "low number of copies " (in which the tumors do not exhibit any of the changes described in the other types) and (4) tumors with predominance of microsatellite instability. In a small number of patients, heterogeneous staining is observed in the evaluation protein expression for mismatch repair genes. Objectives: to evaluate and perform the molecular classifications of cases of endometrial carcinoma with heterogeneous staining by IHC of proteins related to mismatch repair genes and comparison of the molecular profile of positive and negative areas in the IHC study. Cases and Methods: From January/2007 to December/2017 354 cases with EC were identified, 16 of those with HEP. Molecular classification was made based on the PROMISE protocol for EC. Each area (retained and lost expression) was macrodissected and molecular status was evaluated separately regarding MSI status (Idylla), MLH1 promoter methylation (NGS - cutoff for positivity ≥ 15%), POLE status (NGS) and p53 status (IHC). Clinical and pathologic variables were also evaluated and correlated with each case. Results: Endometrioid histology was predominant (15 cases), as absent lymphovascular invasion (11 cases), absence of MELF pattern (10 cases), FIGO Grade 1 and 2 (13 cases), and T1 stage (13 cases). All patients were alive and disease-free at the last follow-up. Two cases that would be described as retained by IHC presented in the molecular analysis as MSI-H. In HEP cases MSH6 was more frequent (9 cases, 7 isolated). MLH1 was altered in 6 cases, and wasthe only protein associated with co-alterations (with MSH6 and PMS2). Six cases were MLH1 methylated, found both in lost and retained areas. As POLE status, there were 6 mutated cases, 2 of those with mutations both in lost and retained areas, and 3 the lost area. Two cases had p53 aberrant pattern (MSH6 altered), that was seen both in the retained and in the lost areas. Conclusion: Correlation between IHC and molecular findings is heterogeneous, and determination between retained or lost expression of MMR proteins by IHC when HEP occurs, however feasible, does not represent the actual molecular alterations. Thus, molecular analysis should be performed every case to adequately determine the intrinsic features of each tumor. Due to the rarity of this finding, this is financially viable and has the potential to change clinical practice in a subset of patients. HEP should be reported as a distinct pattern, and not considered as a synonym expression of retained expression of MMR proteins in EC.

ABSTRACT

Os contraceptivos intrauterinos contendo levonorgestrel, Mirena®, amplamente utilizados na ginecologia contemporânea como método eficaz de contracepção e controle de distúrbios menstruais, mostrou reduzir as taxas de câncer de endométrio. Além disso, complicações como perfuração e migração são raras, exigindo intervenção rápida. Descrição: Dois casos atípicos acerca do uso de dispositivo intrauterino hormonal, o primeiro trata de migração do dispositivo para a cavidade abdominal, após 1 ano e 8 meses da inserção, sem perfuração, com retirada videolaparoscópica. O segundo é um caso de câncer primário de endométrio em paciente com 3 anos de uso de Mirena®. Discussão: A migração do dispositivo intrauterino é uma complicação rara, pouco relatada na literatura, a abordagem videolaparoscópica é a preferencial e foi realizada no caso em questão. O dispositivo intrauterino hormonal também está relacionado à diminuição das taxas de câncer de endométrio e, inclusive, é usado como método preventivo em mulheres de alto risco. Após revisão de literatura, apenas seis casos similares foram descritos. Conclusão: O dispositivo hormonal intrauterino, apesar de seguro, pode implicar apresentações raras, como migração e perfuração, que exigem conhecimento e agilidade da equipe profissional. O segundo caso apresentado é um evento raro, que faz atentar para mulheres com padrão hemorrágico incomum em uso do Mirena®. (AU)


Intrauterine contraceptives containing levonorgestrel, Mirena®, widely used in contemporary gynecology as an effective method of contraception and control of menstrual disorders, have shown to reduce rates of endometrial cancer. In addition, complications such as perforation and migration are rare, requiring rapid intervention. Description: Two atypical cases about the use of intrauterine hormonal device, the first deals with migration of the device to the abdominal cavity, after 1 year and 8 months of insertion, without perforation, with videolaparoscopic withdrawal. The second is a case of primary endometrial cancer in a patient with 3 years of use of Mirena®. Discussion: Migration of the intrauterine device is a rare complication, little reported in the literature, the videolaparoscopic approach is the preferred one and was performed in the case in question. The hormonal intrauterine device is also related to the decreased rates of endometrial cancer and is also used as a preventive method in high-risk women. After reviewing the literature, only six similar cases were described. Conclusion: The intrauterine hormonal device, although safe, may imply rare presentations, such as migration and perforation, which require knowledge and agility of the professional team. The second case presented is a rare event, which makes it aware for women with an unusual hemorrhagic pattern to use Mirena®. (AU)

ABSTRACT

Introducción: El cáncer de endometrio, el cáncer de ovario y el cáncer cervicouterino son las neoplasias, dentro del cáncer del aparato reproductor femenino, que se consideran más frecuentes en la actualidad. La aparición de cáncer ginecológico en mujeres vírgenes demuestra que se deben consideran otras factores causales de la enfermedad, sin embargo, en nuestro país, no hay la suficiente evidencia de documentación sobre estos casos. El objetivo del presente estudio medir la prevalencia de cáncer de cuello uterino, útero y ovarios en mujeres vírgenes atendidas en un centro de referencia de Ginecología Oncológica de Guayaquil. Metodología: El estudio es observacional y transversal, se realizó en el Hospital de Especialidades Teodoro Maldonado Carbo, del Instituto Ecuatoriano de Seguridad Social, Guayaquil-Ecuador, de enero del 2013 al diciembre del 2017. Se incluyeron pacientes con cáncer cervicouterino, de útero y ovarios divididos en Grupo 1 (G1) Mujeres vírgenes y Grupo 2 (G2): Mujeres con vida sexual activa. Las variables fueron edad, órgano afectado, comorbilidades, antecedente familiar de cáncer, tipo histológico y muerte. La muestra fue no probabilística, tipo censo. Se utiliza estadística analítica, la muestra dividida en 2 grupos se compara usando Chi2. Se reporta Odds Ratio con intervalo de confianza del 95%. Resultados: En G1 fueron 44 casos y en G2 fueron 337 casos. Lo que representa una prevalencia de 11.55% (IC95% 11.38-11.71%). Cáncer de Ovario en G1 fue 29/44 casos (66%) versus 95/337 casos (28.2%) en G2 P<0.0001 con OR: 4.92 (2.53-9.60). Cáncer de endometrio en G1 13/44 casos (29.5%) versus 54/337 casos (16%) en G2, OR 2.20 (1.08-4.47) P=0.03. Cáncer cervical en G1 2/44 casos (4.5%) y en G2 188/337 casos (55.8%) OR 0.38 (0.009-0.159) P<0.0001. La mortalidad en G1 fue 30/44 casos en G2 fue 130/337 casos, OR 4.14 (2.12-8.08) P>0.0001. Conclusión: En mujeres sin antecedentes de vida sexual, existe mayor riesgo de cáncer de ovario y de endometrio y el riesgo de cáncer de cérvix se disminuye un 96%. La mortalidad de este grupo de mujeres se duplica por la mayor existencia de cáncer de ovario y endometrial.


Introduction: Endometrial cancer, ovarian cancer and cervical cancer are the neoplasias, within cancer of the female reproductive system, which are considered more frequent today. The appearance of gynecological cancer in virgin women shows that other causal factors of the disease must be considered, however, in our country, there is not enough documentary evidence on these cases. The objective of this study is to measure the prevalence of cervical, uterine and ovarian cancer in virgin women treated in a reference center for Gynecology Oncology in Guayaquil. Methodology: The study is observational and cross-sectional, it was carried out at the Teodoro Maldonado Carbo Specialties Hospital, of the Ecuadorian Social Security Institute, Guayaquil-Ecuador, from January 2013 to December 2017. Patients with cervical, uterine and cervical cancer were includ-ed. ovaries divided into Group 1 (G1) Virgin women and Group 2 (G2): Women with an active sexual life. The variables were age, affected organ, comorbidities, family history of cancer, histological type, and death. The sample was non-probabilistic, census type. Analytical statistics are used, the sample divided into 2 groups is compared using Chi2. Odds Ratio is reported with a confidence interval of 95%. Results: In G1 there were 44 cases and in G2 there were 337 cases. Which represents a prevalence of 11.55% (95% CI 11.38-11.71%). Ovarian cancer in G1 was 29/44 cases (66%) versus 95/337 cases (28.2%) in G2 P <0.0001 with OR: 4.92 (2.53-9.60). Endometrial cancer in G1 13/44 cases (29.5%) versus 54/337 cases (16%) in G2, OR 2.20 (1.08-4.47) P = 0.03. Cervical cancer in G1 2/44 cases (4.5%) and in G2 188/337 cases (55.8%) OR 0.38 (0.009-0.159) P <0.0001. Mortality in G1 was 30/44 cases in G2 it was 130/337 cases, OR 4.14 (2.12-8.08) P> 0.0001. Conclusion: In women with no history of sexual life, there is a greater risk of ovarian and endometrial cancer and the risk of cervical cancer is decreased by 96%. The mortality of this group of women doubles due to the increased existence of ovarian and endometrial cancer

ABSTRACT

Resumen El cáncer de endometrio es la neoplasia ginecológica maligna más frecuente en el sexo femenino. Su presentación metastásica se limita principalmente a los órganos vecinos y ganglios cercanos, y es infrecuente la invasión al tubo digestivo superior. En el presente artículo se presenta una paciente que ingresó al servicio de urgencias con cuadro de hemorragia de vías digestivas altas, enfocado inicialmente como un tumor estromal gastrointestinal (GIST) de la pared gástrica, pero que luego de la realización de una adecuada historia clínica, complementada con imágenes diagnósticas y avances ecoendoscópicos, se logró el diagnóstico de metástasis de cáncer de endometrio.


Abstract Endometrial cancer is the most common gynecologic malignancy in women. Its metastatic presentation is mainly limited to neighboring organs and nearby lymph nodes, and infiltration of the upper digestive tract is uncommon. This case report depicts a patient admitted to the emergency department with upper gastrointestinal bleeding symptoms. Initially, a gastrointestinal stromal tumor (GIST) of the gastric wall was suspected, but endometrial cancer metastasis was discovered after a thorough medical examination, diagnostic imaging, and echoendoscopes.

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

Objective To study the stemness characteristics of uterine corpus endometrial carcinoma(UCEC)and its potential regulatory mechanism.Methods Transcriptome sequencing data of UCEC was obtained from The Cancer Genome Atlas.Gene expression profile was normalized by edgeR package in R3.5.1.A one-class logistic regression machine learning algorithm was employed to calculated the mRNA stemness index(mRNAsi)of each UCEC sample.Then,the prognostic significance of mRNAsi and candidate genes was evaluated by survminer and survival packages.The high-frequency sub-pathways mining approach(HiFreSP)was used to identify the prognosis-related sub-pathways enriched with differentially expressed genes(DEGs).Subsequently,a gene co-expression network was constructed using WGCNA package,and the key gene modules were analyzed.The clusterProfiler package was adopted to the function annotation of the modules highly correlated with mRNAsi.Finally,the Human Protein Atlas(HPA)was retrieved for immunohistochemical validation.Results The mRNAsi of UCEC samples was significantly higher than that of normal tissues(

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

RESUMEN Objetivo: evaluar la exactitud diagnóstica del sistema de puntaje histeroscópico de cáncer endometrial. Materiales y métodos: estudio de exactitud diagnóstica ensamblado en estudio transversal, que incluyó pacientes con sangrado posmenopáusico y engrosamiento endometrial mayor o igual a 5 mm, a quienes se practicó histeroscopia, cuyo resultado se comparó con la biopsia endometrial como patrón de oro diagnóstico, en dos hospitales de alta complejidad. Se midieron variables sociodemográficas, clínicas, puntaje de evaluación histeroscópica y resultado histopatológico de tejido endometrial. En el análisis se estimó sensibilidad, especificidad, razones de probabilidades y área bajo la curva con sus respectivos intervalos de confianza. Resultados: con una prevalencia del cáncer endometrial del 9 %, el sistema de evaluación por histeroscopia mostró una sensibilidad de 75 % (IC 95 %: 30,1-95,43), especificidad de 95,1 % (IC 95 %: 83,9- 98,7), una razón de probabilidades positiva de 15,38 (IC 95 %: 3,55-66,56), una razón de probabilidades negativa de 0,26 y un área bajo la curva del 85 %. Conclusión: el sistema de evaluación endometrial histeroscópico estandarizado mostró una sensibilidad aceptable para hacer la tamización en pacientes con sangrado posmenopáusico y engrosamiento endometrial (≥ 5 mm). Se requiere la realización de estudios con un mayor tamaño muestral que permitan hacer una estimación más precisa de las características operativas de este sistema de evaluación histeroscópico para la detección de cáncer endometrial.


ABSTRACT Objective: To assess the diagnostic accuracy of hysteroscopic scores in endometrial cancer. Materials and methods: Diagnostic accuracy study assembled within a cross-sectional study that included patients with postmenopausal bleeding and endometrial thickening greater than 5 mm in whom hysteroscopy was performed and then compared with endometrial biopsy as the diagnostic gold standard, in two high complexity hospitals. Clinical, sociodemographic variables, as well as hysteroscopic scores and the results of endometrial tissue histopathology were measured. Sensitivity and specificity, likelihood ratios and area under the curve with their respective confidence intervals were estimated in the analysis. Results: With a 9 % prevalence of endometrial cancer, the hysteroscopic assessment system was shown to have 75 % sensitivity (95 % CI; 30.1- 95.43), 95,1 % specificity (95 % CI; 83.9-98.7), a positive likelihood ratio of 15.38 (95 %; CI 3.55- 66.56), a negative likelihood ratio of 0.26 and area under the curve of 85 %. Conclusion: The standardized hysteroscopic assessment system was found to have an acceptable sensitivity for screening in patients with postmenopausal bleeding and endometrial thickening (≥ 5 mm). Further studies with larger sample sizes are required in order to arrive at a more precise estimation of the operational characteristics of the hysteroscopic assessment system for the detection of endometrial cancer.

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

RESUMEN Objetivo: determinar la prevalencia del compro miso ganglionar de pacientes con cáncer de endometrio y hacer una exploración de los factores asociados a la invasión ganglionar. Materiales y métodos: estudio de prevalencia con análisis exploratorio. Se incluyeron pacientes con cáncer de endometrio llevadas a histerectomía abdominal total más salpingooforectomía bilateral y linfadenectomía pélvica, con o sin linfadenectomía paraaórtica en siete centros de oncología de Colombia, en el periodo 2009-2016. Se excluyeron pacientes con radioterapia o quimioterapia previa, diagnóstico histológico de tumores neuroendocrinos, carcinosarcomas, tumores sincrónicos o metacrónicos. Muestreo no probabilístico. Tamaño muestral n = 290. Variables medidas: sociodemográficas, clínicas e histopatológicas y compromiso ganglionar pélvico o paraaórtico. Se presenta la prevalencia de periodo; el análisis exploratorio se realizó por medio de odds ratio (OR) crudo y el ajustado mediante un modelo multivariado (regresión logística no condicional). Resultados: se obtuvieron 467 casos de los cuales se excluyeron 163 por no presentar la totalidad de las variables, se estudiaron 304 pacientes. La prevalencia del compromiso ganglionar fue del 15,8 % (48/304). Los factores asociados al compromiso ganglionar en el análisis crudo y ajustado fueron la invasión linfovascular (OR ajustado = 9,32; IC 95 %: 4,27-21,15) e invasión miometrial (OR ajustado = 3.95; IC 95 %: 1,29-14,98). Conclusión: el 15 % de las pacientes sometidas a linfadenectomía tienen compromiso ganglionar. Se deben evaluar alternativas diagnósticas menos invasivas que la cirugía radical para establecer la invasión ganglionar.


ABSTRACT Objective: To determine the prevalence of lymph node involvement in patients with endometrial cancer and to explore factors associated with lymph node invasion. Materials and methods: Prevalence study with exploratory analysis. The study included patients with endometrial cancer who underwent total abdominal hysterectomy plus bilateral salpyingooophorectomy and pelvic lymphadenectomy with or without para-aortic lymphadenectomy in seven oncology centers in Colombia between 2009 and 2016. Patients who had received prior radiotherapy or chemotherapy, with a histological diagnosis of neuroendocrine tumors, carcinosarcomas or synchronous or metachronous lesions were excluded. Non-probabilistic sampling. Sample size n=290. Measured variables: sociodemographic, clinical and histopathological, and pelvic or para-aortic lymph node involvement. The prevalence for the period is presented. The exploratory analysis was conducted using crude odds ratio (OR) and adjusted OR by means of a multivariate model (unconditional logistic regression). Results: Overall, 467 cases were retrieved. Of them, 163 were excluded because of non-availability of all the variables. In total, 304 patients were studied. The prevalence of lymph node involvement was 15.8 % (48/304). In the crude and adjusted analysis, factors associated with lymph node involvement were lymphovascular invasion (adjusted OR: 9.32; 95 % CI 4.27-21.15) and myometrial invasion (adjusted OR: 3.95; 95 % CI 1.29-14.98). Conclusion: Of the patients undergoing lymphadenectomy, 15 % have lymph node involvement. Less invasive diagnostic options than radical surgery to ascertain lymph node invasion should be assessed.

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

Introducción: La metástasis esplénica de un carcinoma endometrial es un acontecimiento clínico raro, con solo 13 casos documentados en la literatura, revisada. La evolución de esta metástasis, en una paciente atendida, en nuestra Institución, fue el motivo para publicar este trabajo. Hay otras enfermedades oncológicas que en su evolución de progresión o recaída cursan con este tipo de cuadro clínico donde el tratamiento quirúrgico es fundamental y así complementar con tratamiento de quimioterapia. Se hizo una revisión en publicaciones cubanas no se encontró reporte del tema. Objetivo: Presentar un caso con un adenocarcinoma de endometrio tipo endometroide que metastiza al bazo con histología de células claras. Presentación: Paciente de 45 años, con diagnóstico de adenocarcinoma de endometrio con estadiamiento quirúrgico pT3A Nx Mo etapa IIIA Grado 2; este estadiamiento es el anterior a 2009, llevó su tratamiento quirúrgico y radioterapia complementaria, controlada por 21 meses. En consulta de seguimiento se diagnostica metástasis al bazo, por lo que se realiza esplenectomía y es tratada con quimioterapia; fue atendida por el equipo multidisciplinario de ginecología oncológica; las investigaciones realizadas estuvieron basadas en inmuhistoquimica, imageneología y tratamiento de soporte cuando lo necesitó. Conclusiones: La metástasis esplénica por un cáncer de endometrio es rara, es el primero reportado en Cuba, los estudios inmuhistoquímicos y de imágenes son fundamentales(AU)


Introduction: Splenic metastasis from endometrial carcinoma is a rare clinical event with only 13 documented cases in the literature reviewed. The evolution of a patient with this metastasis attended in our institution was the reason that motivated us to publish this work. There are other oncological diseases that are accompanied by this clinical picture during their evolution of progression where surgical treatment complemented with chemotherapy treatment is essential. A literature review was carried out in Cuban publications, but no reports on the topic were found. Objective: The aim of this work is to present an endometroid type case endometrium adenocarcinoma which metastasizes to the spleen with clear cell histology. Case presentation: Forty-five-year-old patient with diagnosis of endometrium adenocarcinoma with surgical stage pT3a Nx Mo stage IIIA Grade 2; this quantification was defined before 2009. The patient underwent surgical treatment which was complemented with radiotherapy and then followed for 21 months. In the follow-up consultation, spleen metastasis was diagnosed; so she underwent splenectomy and was treated with chemotherapy. She was treated by the multidisciplinary gynecologic oncology team; the investigations performed were based on immuhistochemistry, imaging, and supportive treatment whenever needed. Conclusions: Splenic metastasis from endometrial cancer is rare; it is the first case reported in Cuba. Immuhistochemical and imaging studies are essential(AU)
