Clinicopathological characteristics and prognosis of uterine sarcoma: a 10-year retrospective single-center study in China.

BACKGROUND: Uterine sarcoma is a rare and heterogeneous gynecological malignancy characterized by aggressive progression and poor prognosis. The current study aimed to investigate the relationship between clinicopathological characteristics and the prognosis of uterine sarcoma in Chinese patients. METHODS: In this single-center retrospective study, we reviewed the medical records of 75 patients with histologically verified uterine sarcoma treated at the First Affiliated Hospital of Xi'an Jiaotong University between 2011 and 2020. Information on clinical characteristics, treatments, pathology and survival was collected. Progression-free survival (PFS) and overall survival (OS) were visualized in Kaplan-Meier curves. Prognostic factors were identified using the log-rank test for univariate analysis and Cox-proportional hazards regression models for multivariate analysis. RESULTS: The histopathological types included 36 endometrial stromal sarcomas (ESS,48%), 33 leiomyosarcomas (LMS,44%) and 6 adenosarcomas (8%). The mean age at diagnosis was 50.2 ± 10.7 years. Stage I and low-grade accounted for the majority. There were 26 recurrences and 25 deaths at the last follow-up. The mean PFS and OS were 89.41 (95% CI: 76.07-102.75) and 94.03 (95% CI: 81.67-106.38) months, respectively. Univariate analysis showed that > 50 years, post-menopause, advanced stage, ≥ 1/2 myometrial invasion, lymphovascular space invasion and high grade were associated with shorter survival (P < 0.05). Color Doppler flow imaging positive signals were associated with shorter PFS in the LMS group (P = 0.046). The ESS group had longer PFS than that of the LMS group (99.56 vs. 76.05 months, P = 0.043). The multivariate analysis showed that post-menopause and advanced stage were independent risk factors of both PFS and OS in the total cohort and LMS group. In the ESS group, diagnosis age > 50 years and high-grade were independent risk factors of PFS, while high-grade and lymphovascular space invasion were independent risk factors of OS. CONCLUSION: In Chinese patients with uterine sarcoma, post-menopause and advanced stage were associated with a significantly poorer prognosis. The prognosis of ESS was better than that of LMS. Color Doppler flow imaging positive signals of the tumor helped to identify LMS, which needs to be further tested in a larger sample in the future.

Mixed Endometrioid Adenocarcinoma and Müllerian Adenosarcoma of the Uterus and Ovary: Clinicopathologic Characterization With Emphasis on its Distinction From Carcinosarcoma.

Mullerian adenosarcoma is a biphasic neoplasm composed of benign or atypical Müllerian epithelium and a malignant mesenchymal component that is usually, but not always, of low grade. Focal architectural or cytologic atypia of the epithelial component resembling atypical hyperplasia may uncommonly be present and foci of adenocarcinoma have been rarely reported. Whether the coexistence of these 2 tumor components is a result of independent primaries (collision tumor), adenocarcinoma arising from the epithelial component of the adenosarcoma, an unusual form of carcinosarcoma or some other mechanism is uncertain. To establish the diagnostic criteria and clinical significance of the coexistence of adenocarcinoma in close association with Müllerian adenosarcoma, we conducted a multi-institutional study of these rare tumors. Twenty-six patients were identified with "mixed" adenosarcoma and adenocarcinoma; they ranged in age from 43 to 87 years (median: 66 y). Tumors occurred in the uterine corpus (n=22), ovary (n=2), and the pelvis (n=2). All but 6 had International Federation of Gynecology and Obstetrics (FIGO) stage I disease. All extrauterine tumors were associated with endometriosis. The tumor size ranged from 2 to 25 cm (median: 7.9 cm). The sarcomatous component was of low grade in 18 and high grade in 8 (the majority demonstrating rhabdomyoblastic differentiation); 9 had stromal overgrowth. Twenty-five carcinomas were endometrioid in type (23 FIGO grade 1; 3 FIGO grade 2) and 1 carcinoma was dedifferentiated with FIGO grade 1 endometrioid adenocarcinoma component; 33% of the uterine neoplasms were associated with adjacent endometrial hyperplasia. Next-generation sequencing in 2 tumors identified similar molecular abnormalities in the sarcomatous and carcinomatous components supporting a clonal relationship. Of 10 patients with available follow-up (median: 18 mo), 8 had no evidence of disease and 2 died of recurrent sarcoma at 7 and 8 months. Endometrioid adenocarcinomas that arise in close spatial association with Müllerian adenosarcoma appear to be clonally related to the sarcoma. Unlike carcinosarcomas, these tumors are usually early stage at presentation. The prognosis appears to be driven by the sarcomatous component. These tumors should be distinguished from carcinosarcomas, dedifferentiated endometrial carcinomas, and corded and hyalinized endometrioid carcinomas.

[Prognosis-related clinicopathologic characteristics of FIGO stage â Müllerian adenosarcoma of uterus].

Objective: To investigate the clinicopathological features of FIGO stage Ⅰ uterine Müllerian adenosarcoma and clinical prognosis. Methods: Fifteen cases of uterine Müllerian adenosarcoma at FIGO stage Ⅰ were collected at PLA General Hospital from 2005 to 2017. Twelve cases with complete follow-up data were divided into 2 groups: group A (7 patients with survival) and group B(5 patients of death or tumor progression). Clinicopathologic features were compared between the two groups. Results: The median age of the patients was 43 years and 56 years, and the tumor size was 4.3 cm and 7.3 cm for group A and B, respectively. Cases in group A were FIGO ⅠA and ⅠB stage tumors and were mainly low grade in histology (5/7) with rare tumor hemorrhagec, necrosis (1/7) and sarcomatous overgrowth. In contrast, most cases in group B were high grade sarcomas(3/5) with frequent hemorrhage, necrosis(3/5) and sarcomatous overgrowth(4/5). Most cases of group A expressed ER, PR and CD10 (6/7) and low Ki-67 index of ≤20%(5/7). While most group B cases lost expression of ER and PR (3/5), significantly reduced expression of CD10 and higher Ki-67 index of ≥30%(4/5). Conclusions: Most of uterine adenosarcomas are of low malignant potential. The main prognostic indicator is advanced tumor stage. For patients at stage Ⅰ, sarcomatous overgrowth, high-grade histology, deep myometrial invasion, decreased or absent expression of CD10, ER and PR, increased Ki-67 index(≥30%) and hemorrhagic necrosis may indicate poor prognosis. Müllerian adenosarcomas arising from endomeriosis may present unusual growth patterns.

High-grade Müllerian Adenosarcoma: Genomic and Clinicopathologic Characterization of a Distinct Neoplasm With Prevalent TP53 Pathway Alterations and Aggressive Behavior.

Müllerian adenosarcoma harbors low malignant potential, except in cases with myometrial invasion or sarcomatous overgrowth. The presence of a high-grade stromal component has been proposed as an important pathologic predictor of outcome. We hypothesized that high-grade adenosarcoma has distinct clinical and molecular features, distinct from low-grade adenosarcoma. We analyzed the clinicopathologic features and follow-up of 9 high-grade adenosarcomas and a control group of 9 low-grade adenosarcomas. Comprehensive genomic analysis of the high-grade group was performed targeting exons of 409 oncogenes and tumor suppressor genes. In 1 case, the high-grade and low-grade components were separately sequenced. High-grade and low-grade adenosarcomas were comparable in patient age, myometrial invasion, and stage at presentation. Sarcomatous overgrowth was observed in 2/9 (22%) low-grade and 8/9 (89%) high-grade adenosarcomas. Six of 9 (67%) patients with high-grade adenosarcoma developed rapid recurrence; 1 died of her disease. Conversely, no low-grade tumors recurred or metastasized. Sequencing of high-grade adenosarcomas revealed frequent TP53 pathway alterations, identified in 7/9 (78%) cases. p53 expression by immunohistochemistry highly correlated with mutation status. Copy number variations occurred at a mean of 28.8 per tumor; most frequently involved genes included CDK4, MDM2, GNAS, SGK1, and DICER1. High-grade adenosarcoma is an aggressive neoplasm with propensity for short-interval recurrence and metastasis. The proportion of copy number alterations is similar to that reported for adenosarcoma with sarcomatous overgrowth. However, the high frequency of TP53 abnormalities is a novel finding, indicating that high-grade adenosarcoma is a distinct subset with driver TP53 pathway alterations. p53 immunohistochemistry can be used to confirm the presence of a high-grade component. Given its aggressive potential, the presence of any high-grade component in an adenosarcoma should be reported, even in the absence of sarcomatous overgrowth.

Significance of lymph node metastasis on survival of women with uterine adenosarcoma.

OBJECTIVE: Uterine adenosarcoma (UAS) is a rare gynecologic malignancy and the significance of lymph node metastasis on survival has not been well studied. METHODS: A retrospective study was performed utilizing the Surveillance, Epidemiology, End Results Program to examine UAS (n=994), endometrial stromal sarcoma (ESS, n=2910), and uterine leiomyosarcoma (LMS, n=5506) diagnosed between 1973 and 2013. The impact of lymph node metastasis on cause-specific survival (CSS) was cross-compared by multivariable analysis. Systematic literature review was conducted to examine the impact of nodal metastasis on progression-free survival (PFS) in UAS. RESULTS: UAS had the lowest incidence of lymph node metastasis among the sarcoma subtypes examined (UAS 2.9%, LMS 3.4%, and ESS 6.6%, P<0.001). Lymph node metastasis was independently associated with decreased CSS in all three tumor types (all, P<0.01); however, magnitudes of statistical significance of lymph node metastasis for CSS were similar across the three tumor types: adjusted-hazard ratio (aHR) for UAS 2.34, ESS 2.43, and LMS 2.10. Systematic literature review identified 230 unique cases of surgically treated UAS. On multivariable analysis, lymph node metastasis (aHR 4.72) had the greatest degree of significance for PFS compared to other tumor factors including sarcomatous overgrowth (aHR 2.88), heterologous elements (aHR 2.08), and deep myometrial invasion (aHR 1.51). Large tumor, deep myometrial invasion, and sarcomatous overgrowth were associated with increased risk of lymph node metastasis (all, P<0.05). CONCLUSION: While uterine adenosarcoma had a low incidence of lymph node metastasis, the impact of lymph node metastasis on survival was comparable to ESS or LMS.

Uterine adenosarcomas: A dual-institution experience.

There has been limited literature about treatment and follow-up strategies of uterine adenosarcomas because of their rare nature. For this study we retrospectively investigated the medical database of the two major womens' health hospitals in Turkey. A total of 15 patients were identified from the hospital's database. Median follow-up was 86.43 months for all patients. Seven out of 15 patients had recurrences during their follow-up. Among these 7 patients, 4 of them had stage IA disease. Median Disease Free Survival (DFS) and Overall Survival (OS) were calculated as 41.47 and 57.21 months, respectively. According to our study, polypoid tumours confined to the uterus with superficial myometrial invasion can be treated without comprehensive surgical staging. We believe that, publishing all the data in an organised manner even though they are small in size, gives us an opportunity to design meta-analysis for the development of more appropriate treatment strategies.

Survival of women with Mullerian adenosarcoma: A National Cancer Data Base study.

OBJECTIVE: To determine overall survival (OS) and factors associated with OS of women with Mullerian adenosarcoma. METHODS: Women with adenosarcoma of the uterus, cervix or ovary (n=2205) were identified from the 1998-2011 National Cancer Data Base. Kaplan-Meier and multivariate Cox proportional-hazards survival analyses were performed to test for associations of potential explanatory variables with OS. A subset analysis of women with uterine adenosarcoma was also performed. Analyzed confounders included age, insurance status, income, race, surgical margin status, nodal and distant metastasis, surgical procedure type, and treatment with radiation and/or chemotherapy. RESULTS: Primary sites were uterus (n=1884), cervix (n=229) and ovary (n=92), representing 0.43% of uterine, 0.16% of cervical, and 0.04% of ovarian cancers in the NCDB. Only 36/1176 (3.1%) and 2.5% (33/1,342) had nodal and/or distant metastasis, respectively, at diagnosis. Distant metastasis, positive surgical margin, increased age, higher composite comorbidity score and adjuvant radiotherapy were independently associated with decreased OS. Primary site, lymph node status, surgical procedure, chemotherapy use, race, insurance status and income quartiles were not significantly associated with OS. Each 1cm increase in tumor size was associated with increased hazard for death (HR (95% CI) 1.06 (1.01-1.12), p=0.018) among women with uterine adenosarcoma. CONCLUSION: Complete surgical resection remains the only treatment with well-evidenced OS benefit among women with Mullerian adenosarcoma. Early surgical resection may increase survival of Mullerian adenosarcoma.

Management of uterine adenosarcomas with and without sarcomatous overgrowth.

OBJECTIVES: Uterine adenosarcomas (AS) are rare tumors composed of malignant stromal and benign epithelial components. We sought to evaluate the role of primary surgery, adjuvant treatments, and salvage therapies for patients with uterine adenosarcomas. METHODS: We identified all patients diagnosed with AS from 1990 to 2009 at our institution. Patient demographics, surgical procedures, sites of metastatic disease, and histologic features (e.g., presence of sarcomatous overgrowth, and heterologous elements) were collected. Treatment regimens and survival outcomes were evaluated. RESULTS: Thirty-one patients were evaluable for this study: 19 (61%) received up-front treatment at our institution and 12 (39%) received treatment for recurrent disease. Most of the up-front treated patients (15, 79%) were diagnosed with stage I disease and underwent hysterectomy (100%) with bilateral salpingo-oophorectomy (84%). Of the 19 patients treated at our institution from time of initial diagnosis, 5 (26%) patients recurred (median follow-up, 72.9 months; range, 3-154). In 5 patients with sarcomatous overgrowth (AS+SO), the 2-year progression-free and overall survival rates were both 20% versus 100% for 14 patients without sarcomatous overgrowth. Responses to systemic treatment of measurable disease were observed in patients with and without sarcomatous overgrowth, but no optimal treatment strategy could be identified for either groups. CONCLUSIONS: Unlike AS without sarcomatous overgrowth, AS+SO is an aggressive disease with a high recurrence rate. In our series, no optimal adjuvant or systemic treatment strategy was identifiable but standard sarcoma chemotherapy regimens appear to have efficacy in both AS and AS+SO.

Retrospective analysis of 105 cases with uterine sarcoma.

To evaluate the role of adjuvant therapy in survival and to identify important prognostic factors in uterine sarcoma. One hundred five patients with uterine sarcoma have been retrospectively researched to evaluate the results in this tumor group. 43.8% had leiomyosarcoma, 28.6% had endometrial stromal sarcoma and 27.6% had a malign Mullarian mixed tumor while the distribution according to the histological subgroups were found to be 42.6,16.2 and 41.2% in grade I, II and III tumors respectively. 38.1% of the patients had Radiotherapy, 18.1% had chemotherapy and 12.4% had chemoradiotherapy in addition to surgery. The distant metastases rate is 30% and the local recurrence is 16.2%. All the local recurrences and 90% of the distant metastases have occurred within the first two years. The disease free survival and overall survival rates at 3rd and 5th years are 54.46, 49.88, 54.63 and 51.09% all respectively. In our series, univariate analysis for overall survival demonstrated statistical significance for radical surgery, grade, stage, age, menopausal status and presence of RT in treatment modality, but; histology, number of mitosis, tumor size demonstrated no significance. Our data favors treatment for uterine sarcoma with radical surgery plus radiotherapy alone over 54 Gy or with chemotherapy.

Effective bladder sparing therapy with intra-arterial cisplatin and radiotherapy for localized bladder cancer.

PURPOSE: We evaluated the feasibility and efficacy of the organ preserving strategy of intra-arterial cisplatin and concurrent radiotherapy for localized bladder cancer. MATERIALS AND METHODS: Bladder preservation has been pursued over the decades in treatment regimens featuring radiotherapy alone or in conjunction with single or multiagent chemotherapy. The chemotherapy has consisted almost exclusively of intravenously administered drugs. There are theoretical and clinical data demonstrating a higher concentration of cisplatin within tumors following intra-arterial as opposed to intravenous delivery. This study was performed to evaluate whether this increased concentration would enhance radiosensitization and thereby increase the success of bladder preservation. RESULTS: We report on our prospectively collected experience during 15 years of treating 200 patients with localized bladder cancer using this regimen of 3 courses of intra-arterial cisplatin integrated with pelvic radiotherapy and reserving cystectomy for salvage as required. We report on the efficacy in terms of complete response rate, ultimate tumor-free bladder preservation, overall survival and patterns of failure. We detail the acute and chronic toxicity observed to date. CONCLUSIONS: This strategy has resulted in a durable high complete response rate and overall tumor-free bladder preservation rate of 75% while maintaining a survival comparable to that achieved with cystectomy. These results corroborate the hypothesis that intra-arterial administration of cisplatin enhances radiosensitization during pelvic radiotherapy.

Mesodermal (müllerian) adenosarcoma of the ovary: a clinicopathologic analysis of 40 cases and a review of the literature.

Forty cases of mesodermal adenosarcoma of the ovary occurred in women 30-84 years of age (mean 54 years). Abdominal discomfort and distension were the usual complaints. All the patients were treated with an oophorectomy, which was accompanied by a hysterectomy in 85%, a contralateral oophorectomy in 65%, and nonsurgical therapy in 28%. Tumor rupture occurred at or before the operation in 67% of the cases. Twenty-six tumors were stage I, 11 stage II, and 3 stage III. The tumors were unilateral in 97.5% of the cases and 5.5-50 cm (mean 14 cm) in greatest dimension; most of the tumors were predominantly solid but contained numerous small cysts. Microscopic examination revealed sarcomatous overgrowth in 12 tumors. Sex cord-like elements were present in six tumors (including four with sarcomatous overgrowth) and heterologous elements in five (including two with sarcomatous overgrowth). The highest mitotic index of the sarcomatous component was 1-25 (mean 6) mitotic figures per 10 high power fields. Only 6 of 26 women (23%) who were followed postoperatively for > or=5 years were free of tumor. In the other 20 patients recurrent tumor appeared at 0.4-6.6 years (mean 2.6 years) after operation as pure sarcoma (low grade or high grade) or adenosarcoma (with or without sarcomatous overgrowth). Eight women had additional recurrences, and four women had blood-borne metastases. One patient was alive at 15.7 years after the excision of pulmonary metastases. The 5-, 10-, and 15-year survival rates were 64%, 46%, and 30%, respectively. Age <53 years, tumor rupture, a high grade, and the presence of high-grade sarcomatous overgrowth appeared to be associated with recurrence or extraovarian spread. Ovarian adenosarcomas have a worse prognosis than uterine adenosarcomas, presumably because of the greater ease of peritoneal spread. Many of the tumors caused problems in differential diagnosis.

Is vascular and lymphatic space invasion a main prognostic factor in uterine neoplasms with a sarcomatous component? A retrospective study of prognostic factors of 60 patients stratified by stages.

BACKGROUND: Sarcomatous neoplasms of the uterine corpus are still a challenge in terms of obtaining prognostic factors and the most optimum complementary treatment to surgery. The most important prognostic factor is stage; relapses usually appear during the first 2 years, and most patients die within the first 3 years. We have performed a multivariate study of prognostic factors, stratifying patients by stage, to determine their impact on overall survival, disease-free survival, local relapse-free survival, and distant metastasis-free survival. Special emphasis has been given to vascular and lymphatic space invasion (VLSI). METHODS: Sixty patients diagnosed with uterine neoplasms with a main sarcomatous component were treated at Hospital Clínic i Universitari of Barcelona between January 1975 and June 1999. Pathologic type: 32 carcinosarcomas, 14 leiomyosarcomas, 9 adenosarcomas, and 5 endometrial stromal sarcomas. TREATMENT: 58/60 surgery, 35/60 postoperative radiotherapy, 2/60 exclusive chemotherapy, and 3/60 complementary chemotherapy. FIGO stages: 43 Stage I, 4 Stage II, 11 Stage III, and 2 Stage IV. Variables analyzed: age, stage, vascular and lymphatic space invasion, myometrial invasion, mitotic index, tumor size, unicentricity/multicentricity, necrosis, and radiotherapy. STATISTICS: the S and Cox proportional risk models. The partial effect of each risk factor was calculated by hazard ratio (HR) with a confidence interval of 95%. RESULTS: Early stages: Multivariate analysis showed that tumor size larger than 8 cm and VLSI had an impact on overall survival (HR = 4.01 and HR = 24.45, respectively). VLSI was present in 23% of the cases. Myometrial invasion greater than 50% had an impact on disease-free survival and local relapse-free survival (HR was 9.75 and 3.20, respectively). VLSI had an impact on distant metastasis-free survival (HR = 2.92). Advanced stages: VLSI was present in 89% of the cases. Only leiomyosarcoma type made the overall survival worse (HR = 10.54). CONCLUSIONS: Vascular and lymphatic space invasion was a relevant prognostic factor in our series, with an impact on overall survival and distant metastasis-free survival in early stages. In advanced stages, VLSI had no impact on survival, but was present in 89% of cases. Myometrial invasion >50% had an impact on local relapse. Advanced stages had a more aggressive behavior, and there was a higher incidence of poor prognostic factors in these stages. Nevertheless, prospective studies are still needed on prognostic factors and on the best treatment option.

Cluster of uterine mullerian adenosarcoma in the Washington, DC metropolitan area with high incidence of sarcomatous overgrowth.

Mullerian adenosarcoma is an uncommon variant of uterine sarcoma. Twelve uterine adenosarcomas were diagnosed during a 42-month period at the Washington Hospital Center in Washington, DC. Based on estimated incidence data derived from the US Department of Defense beneficiary population, an estimated relative risk of 15.4 (95% confidence interval, 7.7-31.0) was calculated, indicating a significantly increased incidence of adenosarcoma in the population studied (p<0.0000001). Among 10 patients who underwent hysterectomy, six (60%) of their tumors had sarcomatous overgrowth. In comparison with the previously reported proportion of adenosarcomas with sarcomatous overgrowth, approximately 16%, the proportion with sarcomatous overgrowth was significantly higher than expected (p<0.01). Mullerian adenosarcoma with sarcomatous overgrowth was first described in 1989 and suggests that the cluster of adenosarcomas reported herein may be due in part to the current classification of some uterine tumors as adenosarcoma with sarcomatous overgrowth that previously would have been classified as other types of uterine sarcoma. Nonetheless, even after reviewing and updating the classification of all sarcomas diagnosed at the Washington Hospital Center from 1985 to 1998, the ratio of adenosarcomas to uterine adenocarcinomas during the 1994-1998 period was 4.7 times (p<0.005) that of the 1985-1993 period, suggesting a more modest but real increase in the occurrence of this tumor. Correct classification of mullerian adenosarcomas with sarcomatous overgrowth is important because the limited available data suggest that the prognosis is notably worse than that for adenosarcomas without sarcomatous overgrowth.

Prognostic value of flow cytometric deoxyribonucleic acid index in endometrial carcinoma: comparison with other clinical-pathologic parameters.

OBJECTIVE: The aims of the current study were to verify the impact of flow cytometric deoxyribonucleic acid index on clinical outcome in endometrial carcinoma and to assess whether its value is independent from the other clinical-pathologic features. STUDY DESIGN: In a prospective series 74 cases of endometrial carcinoma with surgery performed at our institution were studied. Flow cytometry was performed on fresh tumor samples. The median follow-up period was 31 months (range 8 to 52). Disease-free survival and actuarial survival were the end points of the study. RESULTS: Among the 74 patients (53 with diploid and 21 with aneuploid tumors) there were 14 recurrences and 10 deaths caused by the disease. The recurrence rate was 7.5% for the diploid and 47.6% for the aneuploid tumors (p < 0.001). Mortality was 3.8% for diploid and 38% for aneuploid cases (p < 0.001). Disease-free survival was 89.1% in the former group and 36.3% in the latter. Actuarial survival (Kaplan-Meier method) was 94.7% and 49.5%, respectively. Deoxyribonucleic acid index, stage (International Federation of Gynecology and Obstetrics), and grade of differentiation were significantly correlated with survival, whereas age, depth of myometrial invasion, and histologic type were not. In a multivariate analysis (Cox proportional hazards) deoxyribonucleic acid index was the strongest independent predictor of clinical outcome, followed by International Federation of Gynecology and Obstetrics stage, whereas grade of differentiation yielded no independent prognostic information. CONCLUSIONS: The flow cytometric deoxyribonucleic acid index is an important independent prognosticator, and its determination should be included in the standard management of endometrial cancer.
