High-grade uterine corpus-confined endometrial cancer with lymphadenectomy: does adjuvant therapy improve survival?
Journal Title: Turkish Journal of Obstetrics and Gynecology - Year 2019, Vol 16, Issue 3
Abstract
Objective: To evaluate the necessity of adjuvant therapy and other prognostic factors in high-grade uterine corpus-confined endometrial cancer (EC) with lymphadenectomy performed. Materials and Methods: This study included 120 patients who had endometrioid-type grade 3, serous-type, clear cell-type, and undifferentiated-type EC and underwent lymphadenectomy. Results: Patients with high-grade uterine corpus-confined EC who underwent lymphadenectomy were evaluated. The modality of adjuvant therapy performed was not a predictor for the site of recurrence. The loco-regional recurrence rate decreased from 9.5% to 3.8% in patients who received radiotherapy. However, this difference was not statistically significant (p=0.206). In addition, performing adjuvant chemotherapy did not alter the risk of extrapelvic recurrence. Only International Federation of Gynecology and Obstetrics 2009 stage was significant in the univariate analysis. On the other hand, age, tumor type, number of removed lymph nodes, presence of myometrial and lymphovascular space invasion, tumor size and adjuvant therapy modality were not related with disease-free survival. Conclusion: Performing adjuvant therapy and therapy modality does not improve oncologic outcomes in intermediate and high-risk patients. However, radiotherapy reduced the risk of local recurrence by more than 50%. Vaginal brachytherapy was efficient as external beam radiotherapy. Therefore, vaginal brachytherapy should be used for these patients in order to reduce loco-regional recurrence even if it is not reported to be effective on disease-free survival.
