Objective: To investigate the role of radiotherapy (RT) in patients who underwenthysterectomy for uterine carcinosarcoma (UCS). Methods: Patients with the International Federation of Gynecology and Obstetrics stage I–IVa UCS who were treated between 1990 and 2012 were identified retrospectively in a multiinstitutionaldatabase. Of 235 identified patients, 97 (41.3%) received adjuvant RT. Twentytwopatients with a history of previous pelvic RT were analyzed separately. Survival outcomeswere assessed using the Kaplan-Meier method and Cox proportional hazards model. Results: Patients with a previous history of pelvic RT had poor survival outcomes, and 72.6%of these patients experienced locoregional recurrence; however, none received RT after adiagnosis of UCS. Univariate analyses revealed that pelvic lymphadenectomy (PLND) andpara-aortic lymph node sampling were significant factors for locoregional recurrence-freesurvival (LRRFS) and disease-free survival (DFS). Among patients without previous pelvicRT, the percentage of locoregional failure was lower for those who received adjuvant RT thanfor those who did not (28.5% vs. 17.5%, p=0.107). Multivariate analysis revealed significantcorrelations between PLND and LRRFS, distant metastasis-free survival, and DFS. Insubgroup analyses, RT significantly improved the 5-year LRRFS rate of patients who did notundergo PLND (52.7% vs. 18.7% for non-RT, p<0.001).

Given the poorer locoregional outcomes of patients previously subjected to pelvic RT, meticulous re-administration of RT might improve locoregional control while leading to less toxicity in these patients.
