Abstract

Objective: The objective of this study was to evaluate how the administration of different adjuvant therapies influences the risk for developing recurrences in the para-aortic area in endometrial cancer (EC) with positive pelvic and unknown para-aortic nodes. Methods: We retrospectively evaluated the data of 58 patients with EC affected by stage IIIC1 who had undergone pelvic but not para-aortic lymphadenectomy from January 1, 1990 to December 31, 2011. Survival outcomes within the first 5 years after surgery were assessed using the Kaplan-Meier model. Results: Chemotherapy plus radiotherapy, chemotherapy only, and external radiotherapy only were administered in 12 (23%), 18 (34%), and 23 (43%) patients, respectively. Five (9%) patients, whowere selected to forego adjuvant therapy due to poor performance status, were excluded from the analysis. Disease-free and overall survivals assessed at 5 years were 54%, and 61%, respectively. All para-aortic recurrences were observed among the patients with endometrioid EC, whereas no cases of para-aortic recurrenceswere found in patientswith nonendometrioid histology (5/36 (14%) vs 0/17 (0%); P = 0.16); the latterwere more likely to develop distant (hematogenous, peritoneal, and distant lymphatic) recurrences (P = 0.09). Type of adjuvant therapy was the only factor influencing para-aortic failure: chemotherapy (± radiotherapy) reduced the rate of paraaortic node recurrence in comparison with pelvic radiotherapy as a sole modality (P = 0.01). However, adjuvant therapy did not influence the 5-year survival outcomes (P > 0.05). Conclusions: In the absence of local treatment (ie, para-aortic lymphadenectomy and radiotherapy), the administration of chemotherapy seems effective in reducing recurrences in the para-aortic area among patients with stage IIIC1 endometrioid EC.
