Lymphovascular Space Invasion

ObjectivesTreatment of clinical early-stage endometrioid endometrial cancer (EEC) in The Netherlands consists of primary hysterectomy and bilateral salpingo-oophorectomy. Adjuvant radiotherapy is given when 2 or more the following risk factors are present: 60 years or older, grade 3 histology, and 50% or more myometrial invasion. Lymphovascular space invasion (LVSI) is a predictor of poor prognosis and early distant spread. It is unclear whether adjuvant radiotherapy is sufficient in patients with LVSI-positive EEC.Methods/MaterialsEighty-one patients treated from 1999 until 2011 for stage I LVSI-positive EEC in 11 Dutch hospitals were included. The outcomes of patients with 0 to 1 risk factors were compared with those with 2 to 3 risk factors, and both were compared with the known literature.ResultsEighteen patients presented with recurrent disease, and 12 of those recurrences had a distant component. Overall and distant recurrence rates were 19.2% and 11.5% in patients with 0 to 1 risk factors followed by observation and 25.5% and 17% in patients with 2 to 3 risk factors who received adjuvant radiotherapy. Only 1 patient with grade 1 disease had a recurrence.ConclusionsIn stage I LVSI-positive EEC with 0 to 1 risk factors, observation might not be adequate. Moreover, despite adjuvant radiotherapy, a high overall and distant recurrence rate was observed in patients with 2 to 3 risk factors. The use of systemic treatment in these patients, with the exception of patients with grade 1 disease, should be investigated.

Objective: Although endometrial cancer (EC) is a hormone dependent neoplasm, there are no recommendations for the determination of steroid hormone receptors in the tumor tissue and no hormone therapy has ever been assessed in the adjuvant setting. The purpose of this study was to explore the effect of adjuvant aromatase inhibitors (AIs) on progression-free survival (PFS) and overall survival (OS) in patients with early stage and steroid receptors-positive EC. Methods: We retrospectively analyzed clinical and pathological factors in 73 patients with high-risk (49.3%) or low-risk (50.7%) stage I (n = 71) or II (n = 2) endometrial cancer who received by their preference after counseling either no treatment (reference group) or AI. Prognostic factors were well balanced between groups. Expression of estrogen receptor (ER), progesterone receptor (PgR), and Ki-67 index was correlated with clinical outcomes. Results: Univariate and multivariate Cox proportional regression analyses, adjusted for age, grade, stage, depth of myometrial invasion, lymphovascular space invasion, BMI, ER, PgR and Ki-67 labeling index levels, showed that PFS and OS had a trend to be longer in patients receiving AI than in the reference group HR= 0.23 (95% CI; 0.04–1.27) for PFS and HR= 0.11 (95% CI; 0.01–1.36) for OS. Conclusion: Compared with no treatment, AI exhibited a trend toward a benefit on PFS and OS in patients with early stage hormone receptor-positive EC. Given the exploratory nature of our study, randomized clinical trials for ER/PgR positive EC patients are warranted to assess the clinical benefit of AI and the potential predictive role of steroid receptors and Ki-67.

ObjectiveThe aim of this study was to evaluate recurrence patterns and survival outcomes for patients with early-stage non-endometrioid endometrial adenocarcinoma treated with adjuvant high-dose rate vaginal brachytherapy with a low-dose scheme.MethodsA retrospective review was performed of patients with International Federation of Gynecology and Obstetrics (FIGO) stage I–II non-endometrioid endometrial cancer who received adjuvant vaginal brachytherapy with a low-dose regimen of 24 Gy in six fractions from November 2005 to May 2017. All patients had >6 months of follow-up. Rates of recurrence-free survival, overall survival, vaginal, pelvic, and distant recurrence were calculated by the Kaplan–Meier method. Prognostic factors for recurrence and survival were evaluated by Cox proportional hazards modeling.ResultsA total of 106 patients were analyzed. Median follow-up was 49 months (range 9–119). Histologic subtypes were serous (47%, n=50), clear cell (10%, n=11), mixed (27%, n=29), and carcinosarcoma (15%, n=16). Most patients (79%) had stage IA disease, 94% had surgical nodal assessment, and 13% had lymphovascular invasion. Adjuvant chemotherapy was delivered to 75%. The 5-year recurrence-free and overall survival rates were 74% and 83%, respectively. By histology, 5-year recurrence-free/overall survival rates were: serous 73%/78%, clear cell 68%/88%, mixed 88%/100%, and carcinosarcoma 56%/60% (p=0.046 and p<0.01). On multivariate analysis, lymphovascular invasion was significantly associated with recurrence (HR 3.3, p<0.01). The 5-year vaginal, pelvic, and distant recurrence rates were 7%, 8%, and 21%, respectively. Vaginal and pelvic recurrence rates were highest for patients with carcinosarcoma, lymphovascular invasion and/or FIGO stage IB/II disease. At 5 years, vaginal and pelvic recurrence rates for patients with lymphovascular invasion were 33% and 40%, respectively. Patients with stage IA disease or no lymphovascular invasion had 5-year vaginal recurrence rates of 4% and pelvic recurrence rates of 6% and 3%, respectively.ConclusionsAdjuvant high-dose rate brachytherapy with a low-dose scheme is effective for most patients with early-stage non-endometrioid endometrial cancer, particularly stage IA disease and no lymphovascular invasion. Pelvic radiation therapy should be considered for those with carcinosarcoma, lymphovascular invasion and/or stage IB/II disease.

ObjectiveLimited data have been obtained in regard to pulmonary metastasis (PM) in patients with stage I endometrial cancer. The aims of the study were (1) to present the clinical and pathological characteristics of patients with PM in the setting of stage I endometrioid-type endometrial cancer (EEC) and (2) to define possible factors that may be used to predict PM.MethodsSix hundred thirty patients with stage I EEC, including 12 with PM, 19 with extra-PM (EPM), and 599 with no recurrence, were observed. Paired samples of primary and metastatic tumors from a patient were used for exome sequencing to identify potential gene mutations associated with PM.ResultsThere was no significant difference in the age, Ki-67, lymphatic vascular space invasion, and grade 3 among the 3 groups (P > 0.05). More squamous epithelial differentiation was observed in PM (7/12), as compared with patients with EPM (1/19) (P < 0.05) and no recurrence (20/599) (P < 0.05). The tumor size of the patients with PM was bigger than that of nonrecurrent patients (29.8 ± 16.6 vs 18.5 ± 16.3 mm, P < 0.05). More percentage of patients with deep myometrial invasion (IB) were found in PM (6/12) (P < 0.05) as compared with patients with EPM (3/19) (P < 0.05) and no recurrence (76/599). CDH10, ARID1A, and EMT-associated gene mutations were identified in metastatic tumor tissue but not in primary tumors from a patient with EEC and lung metastases.ConclusionsSquamous epithelial differentiation, large tumor size, and deep myometrial invasion might be risk factors for PM in patients with stage I EEC. CDH10, ARID1A, and EMT-associated gene mutation may promote the initiation of lung recurrence. However, further studies are needed to determine the precise mechanisms associated with lung metastasis in these patients.

ObjectiveThe role of adjuvant chemotherapy as an addition or alternative to radiotherapy for early-stage high-risk endometrioid endometrial cancer is controversial. This study aimed to investigate the role of adjuvant chemotherapy in early-stage high-risk endometrioid endometrial cancer.MethodsWe identified patients with stage I or II endometrioid grade 2 or 3 endometrial cancer with myometrial invasion >50% and negative lymph nodes after pelvic with or without para-aortic lymphadenectomy at four institutions (USA and Italy). Associations between chemotherapy and cause-specific and recurrence-free survival were assessed with Cox proportional hazards models. Hematogenous, peritoneal, and lymphatic recurrences were defined as 'non-vaginal'.ResultsWe identified 329 patients of mean (SD) age 66.4 (9.8) years. The median follow-up among those alive was 84 (IQR 44–133) months. The 5-year cause-specific survival was 86.1% (95% CI 82.0% to 90.4%) and the 5-year recurrence-free survival was 82.2% (95% CI 77.9% to 86.8%). Stage II (vs stage IB) was associated with poorer cause-specific and recurrence-free survival. A total of 58 (90.6%) of 64 patients who had chemotherapy had 4–6 cycles of platinum-based regimen. In adjusted analysis, we did not observe a statistically significant improvement in cause-specific survival (HR 0.34; 95% CI 0.11 to 1.03; p=0.06) or non-vaginal recurrence-free survival (HR 0.36; 95% CI 0.12 to 1.08; p=0.07) with adjuvant chemotherapy. Sixteen of 18 lymphatic recurrences (88.9%; 3/5 pelvic, all 13 para-aortic) were observed in the 265 patients who did not receive adjuvant chemotherapy. Among stage II patients, no deaths (100% 5-year recurrence-free survival) were observed in the eight patients who received adjuvant chemotherapy compared with 66% 5-year recurrence-free survival in the 34 patients who did not.ConclusionAlthough we observed that adjuvant chemotherapy was associated with improved oncologic outcomes in early-stage high-risk endometrioid endometrial cancer, the associations did not meet conventional levels of statistical significance. Further research is warranted in this relatively uncommon subgroup of patients.

Purpose To estimate whether pelvic and para-aortic lymphadenectomy was associated with increased survival in stage I endometrioid endometrial cancer. Methods We performed matched cohort analyses of women with stage I endometrioid endometrial cancer who underwent hysterectomy with no lymphadenectomy, pelvic lymphadenectomy, or combined pelvic and para-aortic lymphadenectomy. Cox proportional hazards survival analyses were performed with inverse probability weights. Hazard ratios (HRs) were covariate and propensity score adjusted. Covariates included cancer center type, age, race, Hispanic ethnicity, insurance type, community median income quartile, comorbidity score, history of prior cancer, depth of myometrial invasion, tumor grade, tumor size, lymphovascular space invasion, cytology status, surgical margin status, hospital volume, and use of adjuvant radiotherapy or chemotherapy. Additional analyses included subset analyses by grade, sensitivity analyses with imputation of missing data, and testing for sensitivity to possible unmeasured confounding. Results Median (interquartile range [IQR]) lymph node counts were 0, 10 (5-15), and 20 (15-27) nodes in the no lymphadenectomy, pelvic, and combined pelvic and para-aortic lymphadenectomy–matched cohorts, respectively. Matched cohorts were well balanced. Two analyses were performed: no lymphadenectomy (n = 7,487) versus pelvic lymphadenectomy (n = 7,487), and pelvic lymphadenectomy (n = 7,060) versus combined pelvic and para-aortic lymphadenectomy (n = 7,060). Performance of pelvic lymphadenectomy was associated with increased survival compared with no lymphadenectomy (5-year survival [95% CI], 91.4% [90.2% to 92.6%] v 87.3% [85.9% to 88.8%]; HR, 0.71 [95% CI, 0.64 to 0.78]; P < .001). Addition of para-aortic lymphadenectomy was associated with increased survival compared with pelvic lymphadenectomy alone (5-year survival [95% CI], 91.0% [89.8% to 92.2%] v 89.8% [88.4% to 91.1%]; HR, 0.85 [95% CI, 0.77 to 0.95]; P = .003). Associations were robust to sensitivity analyses. Conclusion Lymphadenectomy was associated with increased survival in stage I endometrioid endometrial cancer. An adequately powered randomized trial is needed.
