Uterine Serous Carcinoma

5517 Background: Uterine serous carcinoma is a less common subtype of endometrial cancer that is associated with poorer survival. The optimal post-operative adjuvant treatment strategy for these patients remains uncertain. Methods: This multi-institutional, retrospective cohort study evaluated patients with early stage uterine serous carcinoma. Patients with FIGO Stage IA-II disease after surgery, whose tumors had serous or mixed serous/non-serous histology were included. Patients with carcinosarcoma were excluded. Clinical data were abstracted from local medical records. Summary statistics, Fisher’s exact, and Kruskal-Wallis tests were used to analyze demographic and clinical characteristics. Univariable and multivariable analyses were performed for recurrence-free survival (RFS) and overall survival (OS). Results: 634 patients were included. 77% of patients had Stage IA disease, 42% showed no myometrial invasion. The majority had pure serous histology (72%) and LVSI (76%). Adjuvant treatment varied: 12% received no adjuvant therapy, 7% had chemotherapy alone, 51% had cuff brachytherapy, 12% had cuff brachytherapy with chemotherapy (cuff/chemo), and 19% underwent pelvic radiation (EBRT). Complete RFS and OS data were available for 607 and 609 patients, respectively, and the median follow-up time was 58 months. As compared with patients who received no adjuvant therapy, patients who received cuff or cuff/chemo had improved RFS (cuff: HR 0.70, p = 0.02; cuff/chemo HR 0.53, p = 0.01) and OS (cuff HR 0.56, p = 0.001; cuff/chemo HR 0.48, p = 0.01). In a direct comparison, patients with cuff/chemo had better RFS and OS than those with chemotherapy alone (RFS HR 0.52, p = 0.03; OS HR 0.50, p = 0.05). There were no differences in RFS or OS for women who received chemotherapy alone or EBRT. Improved survival with cuff and cuff/chemo persisted on multivariable analyses (included age, stage, LVSI, adjuvant therapy type); additionally, EBRT was also associated with improved OS. In analyses limited to patients without myometrial invasion, patients with cuff or cuff/chemo had improved RFS and OS compared with observation alone. Conclusions: The use of adjuvant cuff brachytherapy with and without chemotherapy was associated with improved RFS and OS in patients with early stage uterine serous carcinoma.

ObjectiveOur aim was to evaluate the prognostic significance of the revised 2009 International Federation of Gynecology and Obstetrics (FIGO) staging criteria in patients with uterine serous carcinoma (USC).Materials and MethodsWe retrieved clinical and histopathologic data on women with USC from 2 large academic centers. Age, race, stage, myometrial invasion, angiolymphatic invasion, and adjuvant therapy were analyzed using Kaplan-Meier and Cox regression models.ResultsA total of 168 patients were included. Three-year survival rate was 81% for revised stage I, 52% for stage II, 46% for stage III, and 19% for stage IV. Survival was not significantly different when comparing overall 1988 FIGO stage I or II to 2009 FIGO stage I or II. The 3-year survival rate for 1988 stage IA (93%), IB (75%), and IC (60%) significantly differed (P = 0.02). When patients were restaged using the 2009 staging system, the 3-year overall survival of 2009 stage IA dropped to 83.4% and 68.8% for stage IB. New FIGO stage, myometrial invasion, angiolymphatic invasion, and administration of chemotherapy all remained independent predictors of survival on multivariate analysis (P < 0.05). Of note, extrauterine disease was observed in 22% of patients without myometrial invasion. Age and race were not prognostic factors for either classification.ConclusionsThe streamlined 2009 FIGO criteria do not adequately delineate survival for USC in early-stage disease. The 1988 FIGO classification correctly identified 3 subgroups of stage I USC patients with significantly different survival that is lost with the elimination of the most favorable 1988 stage IA subgroup. Because evaluation for adjuvant therapy and patient planning may change based on survival information, further evaluation of more appropriate USC staging is warranted. Caution should be taken when evaluating therapeutic response and comparing studies using these revised criteria in the future.

e16556 Background: The choice of adjuvant therapy for early-stage USC remains controversial. The objective of this study was to estimate the recurrence rates of patients with surgically resected early-stage USC stratified by observation alone or adjuvant therapy. Methods: A retrospective review of women with surgically-staged stage IA-II USC followed at M.D. Anderson Cancer Center between January 2000 and December 2011. Descriptive statistics were used to summarize the demographic and clinical characteristics of patients. We estimated the cumulative incidence of disease recurrence, overall survival (OS), and recurrence-free survival (RFS) as a function of adjuvant therapy received. Adjuvant therapy groups listed in the Table. Results: 80 patients included in study. 58 patients had stage IA, 14 had stage IB, and 8 had stage II disease. Mean age was 66.4 years. Median follow-up for all patients was 4.83 years (range: 0.02 – 18.16). Cumulative incidence of recurrence for the whole group was 0.18 (95% CI: 0.10 – 0.28) which was reached at 3.96 years and remained at this rate until rising to 0.23 (95% CI: 0.12 – 0.36) at 11.12 years. Adjuvant treatment was not significantly associated with decreased risk of recurrence (Table). RFS at 5 years for the whole population was 0.71 (95% CI: 0.59 – 0.80) and OS at 5 years was 0.76 (95% CI: 0.63 – 0.85). Adjuvant treatment was not significantly associated with RFS or OS. In a subset of stage IA patients, 4 of 27 patients in the observation or cuff alone group recurred compared with 1 of 16 patients in the chemotherapy +/- cuff group (HR 0.48, CI: 0.05 – 4.27, p=0.511). Conclusions: In this study, there were no observed differences between observation and adjuvant treatment modalities in recurrence rates or survival outcomes for patients with early-stage USC. The addition of adjuvant chemotherapy may reduce risk for recurrence in stage IA patients, but further study is needed. [Table: see text]

e17567 Background: Early-stage endometrial cancer (EEC) with FIGO stage I-II generally has a favorable prognosis and overall survival (OS). However, up to 10% of EEC patients (pts) relapse and risk factors for recurrence remain unclear. We evaluated clinical and histopathologic characteristics of EEC and correlated them with OS and recurrence free survival (RFS) through a single-center retrospective analysis. Methods: We conducted a retrospective chart review on 511 pts with EEC identified by our cancer registry from 1/1/2009 to 12/31/2019. The two main histologic groups were endometrioid adenocarcinomas (E) and other subtypes (O) including carcinosarcoma, undifferentiated, and clear cell carcinomas. Papillary serous histology was excluded. Histopathologic and clinical findings recorded included age, FIGO stage and grade, tumor size, presence of recurrence, adjuvant therapies received, percent of myometrial invasion (MI), and lymphovascular invasion (LVI). OS and RFS were estimated, and each predictor was compared using the log-rank test. The association between OS and each continuous characteristic was examined using the Cox proportional hazards model. Factors significantly associated with OS and RFS in the univariable analysis (p < 0.05) were included in a multivariable analysis to examine the joint effects of those factors on survival. Results: A total of 511 cases were reviewed. The analysis included 501 pts (E = 485, O = 16), of which 47 had recurrent disease (E = 45, O = 2) and 17 had died without recurring (E = 15, O = 2) as of their last follow-up. Overall median age was 63 years. Factors significantly associated with recurrence in the multivariable analysis were FIGO grade, (Hazard Ratios (HR): Grade 2 vs 1: 1.95, 95% CI: 1.06-3.58, p = 0.0320, Grade 3 vs 1: 2.88, 95% CI: 1.50-5.52, p = 0.0015), LVI (HR: 2.03, 95% CI: 1.10-3.75, p = 0.0244), and greater than 50% of MI (HR: 3.15, 95% CI: 1.35-7.36, p = 0.0080). The overall RFS was 92% and 86% at three and five years, respectively. On univariate analysis, among pts with a measurable tumor size (n = 446), larger tumors were not significantly associated with OS (p = 0.65) but was associated with increased recurrence (HR 1.22, 95% CI: 1.10-1.37, for a unit increase, p = 0.0003). On univariate analysis, pts who received adjuvant therapy were more likely to recur (p = 0.0002) with RFS of 86% and 76% at three and five years respectively, versus RFS of 94% and 90%, for those who did not. Conclusions: We confirmed the clinical and histopathologic characteristics that are currently considered to increase risk of recurrence in EEC. On multivariate analysis, risk of recurrence was associated with FIGO grades 2 and 3, presence of LVI, and > 50% MI. A limitation of this study is the lack of molecular analysis. Further molecular stratification may help us identify the subset of pts who are at high risk of recurrence, enabling customized adjuvant therapy in EEC.

The Impact

ObjectivesThe role of adjuvant treatment for early-stage uterine serous carcinoma is not defined. The goal of this study was to investigate the impact of adjuvant treatment on survival of patients with tumors confined to the endometrium.MethodsPatients diagnosed with stage I uterine serous carcinoma with no myometrial invasion between January 2004 and December 2015 who underwent hysterectomy with at least 10 lymph nodes removed were identified from the National Cancer Database. Adjuvant treatment patterns defined as receipt of chemotherapy and/or radiotherapy within 6 months from surgery were investigated and overall survival was evaluated using Kaplan–Meier curves, and compared with the log-rank test for patients with at least one month of follow-up. A Cox analysis was performed to control for confounders.ResultsA total of 1709 patients were identified; 833 (48.7%) did not receive adjuvant treatment, 348 (20.4%) received both chemotherapy and radiotherapy, 353 (20.7%) received chemotherapy only, and 175 (10.2%) received radiotherapy only. Five-year overall survival rates for patients who did not receive adjuvant treatment (n=736) was 81.9%, compared with 91.3% for those who had chemoradiation (n=293), 85.1% for those who received radiotherapy only (n=143), and 91.0% for those who received chemotherapy only (n=298) (p<0.001). After controlling for age, insurance status, type of treatment facility, tumor size, co-morbidities, and history of another tumor, patients who received adjuvant chemotherapy (HR 0.64, 95% CI 0.42, 0.96), or chemoradiation (HR 0.55, 95% CI 0.35, 0.88) had better survival compared with those who did not receive any adjuvant treatment, while there was no benefit from radiotherapy alone (HR 0.85, 95% CI 0.53, 1.37). There was no survival difference between chemoradiation and chemotherapy only (HR 1.15, 95% CI 0.65, 2.01).ConclusionAdjuvant chemotherapy (with or without radiotherapy) is associated with a survival benefit for uterine serous carcinoma confined to the endometrium.

e19092 Background: The study aimed to identify whether there were racial disparities in the clinicopathologic features and genetic mutation characteristics between African American (AA) and Caucasian women with uterine serous carcinoma. Methods: Clinicopathologic features, molecular genetic data of patients with uterine serous carcinoma were obtained from The Cancer Genome Atlas (TCGA), including age of diagnosis, body mass index (BMI), tumor grade, FIGO stage, myometrial invasion, lymph node involvement, overall survival and progression free survival. MLH1, MSH2, MSH6, PMS2, BRCA1, BRCA2, CHEK2, TP53 mutations were involved. A statistical analysis of these parameters was performed for AA and Caucasian women. Results: 44 AA and 97 Caucasian patients with uterine serous carcinoma were analyzed. There were no PMS2 and BRCA2mutations in tumors of African American patients. Compared to Caucasian patients, tumors from AA patients had no statistically significant differences in Lynch syndrome related genes ( MSH2, MSH6, PMS2) (4.5% versus 14.3%, p = 0.149) and HR pathway genes ( BRCA1, BRCA2, CHEK2) (9.1% versus 19.6%, p = 0.09). Tumors from AA patients had no statistically significant differences in alterations of the TP53 gene (79.5% versus 71.3%, p = 0.312). There were no statistically significant differences between the two groups regarding age at diagnosis, BMI, tumor histology, tumor grade, lymph node involvement, myometrial invasion, FIGO stage, overall survival or progression-free survival between the two groups ( p > 0.05). Conclusions: This study identified no statistically significant differences in clinicopathologic features and genetic mutations in AA and Caucasian women with uterine serous carcinomas. Especially, there were no differences in survival identified between two groups. Much larger database may be necessary to be analyzed in future. [Table: see text]

Uterine Serous Carcinoma

Background: Uterine serous carcinoma is a rare histologic subtype of endometrial cancer. Oncologic outcomes for this disease are sparsely reported, and adjuvant therapy after surgery is considerably heterogeneous. Objective: To determine the 2-year recurrence rate, recurrence-free survival, overall survival, and associated factors among patients with uterine serous carcinoma after surgical treatment at Siriraj Hospital. Materials and Methods: One hundred thirty uterine serous carcinoma patients diagnosed between December 2007 and June 2015 were enrolled. Patients who did not undergo surgery as a primary treatment or not achieve clinically complete response were excluded. Pathological slides were reviewed. Data were retrieved from the medical records including gynecologic data, surgical and pathological results, post-operative treatment, response status, recurrence status, and follow-up data. The recurrence rate at two years was calculated. Recurrence-free survival and overall survival were analyzed, and various characteristics were used to determine associated treatment outcomes. Results: One hundred nine patients were analyzed, 50 in stage I, 15 in stage II, 38 in stage III, and six in stage IV. Median follow-up time was 23 months. At two years, the recurrence rate was 35.8%. Post-operative treatment was performed in 91.7%, and chemotherapy was the most common modality used. Eleven patients (16.9%) in early-stage and twenty-five patients (56.8%) in the advanced stage had disease recurrence. Thirty patients (83.3%) had disease recurrence intra-abdominal or multiple metastases. No patient in stage I that received adjuvant chemotherapy had relapsed disease. Two-year recurrence-free survival and 2-year overall survival were 71.2% and 83.4%, respectively. FIGO staging was the only factor associated with recurrence-free survival. Conclusion: Uterine serous carcinoma represents a rare disease with a high recurrence rate and poor prognosis. FIGO staging is related to recurrence-free survival. Adjuvant chemotherapy showed survival benefits in early-stage uterine serous carcinoma. Keywords: Uterine serous carcinoma, Adjuvant therapy, Recurrence, Survival

Uterine Serous Carcinoma

6084 Background: Uterine serous carcinoma (USC) is a rare and aggressive malignancy, accounting for 40% of all endometrial cancer deaths. Human Epidermal Growth Factor Receptor 2 (HER2) has emerged as an important prognostic and therapeutic target in USC. Given recent randomized trial results, HER2-directed therapy is now recommended in advanced-stage or recurrent, HER2-positive disease. The significance of tumoral HER2 expression in early-stage disease has not yet been established. Methods: In this IRB-approved, retrospective, multi-institutional cohort, women diagnosed with stage I USC from 2000-2018 were identified. Patient demographic, treatment, and survival data were collected. Immunohistochemistry (IHC) was performed for HER2 and scored 0-3+. Equivocal IHC results (2+) were further tested with in-situ hybridization (ISH) per the 2007 ASCO-CAP HER2 breast cancer guidelines. HER2 overexpression (“positive”) was defined as 3+ IHC or ISH positive. Kaplan-Meier analyses and Cox-proportional hazards were used to compare survival between the cohorts. Results: In total, 173 patients with stage I USC were tested for HER2; 25% were HER2-positive, 77.4% had stage IA and 22.6% had stage IB disease. Adequate clinical follow up was available for 168 patients. There were no significant differences in age, race/ethnicity, body mass index, surgical management, sub-stage, tumor size, adjuvant therapy, or follow-up duration between the HER2-positive and negative cohorts. On univarite analysis, presence of lymph-vascular space invasion was correlated with HER2-positive tumors (p=0.003). After a median follow-up of 50 months, there were 41 (24.4%) recurrences. Significantly more recurrences were observed in the HER2-positive cohort (47.6% vs. 16.7%, p<0.001). HER2 overexpression was also associated with poorer progression-free (PFS) and overall survival (OS) (p<0.001 and p=0.012). After adjusting for prognostic factors including sub-stage and adjuvant treatment, those with HER2-positive tumors experienced inferior PFS (aHR 3.67, 95%CI 1.92-6.98; p<0.001) and OS (aHR 2.03, 95%CI 1.03-4.01; p=0.042) compared to HER2-negative tumors. Conclusions: Uterine serous carcinoma is a poor prognostic tumor, even in patients with early-stage disease. Given its significant association with worse survival outcomes, tumoral HER2 overexpression appears to be a prognostic biomarker in women with stage I disease. These data provide rationale for clinical trials with HER2-directed therapy in early-stage uterine serous carcinoma.
