    Abstract:
    PURPOSE: To determine retrospectively whether radical surgery plus postoperative radiotherapy (RT) is superior to definitive RT from the standpoint of disease control and adverse events in the treatment of stages IB-IIA and stage IIB cervical squamous cell carcinoma. MATERIALS AND METHODS: The study included 143 patients treated by definitive RT (stages IB-IIA, n = 15; stage IIB, n = 27) or postoperative RT (stages IB-IIA, n = 67; stage IIB, n = 34). Cause-specific survival (CSS) and recurrence-free rate (RFR) were estimated. Late adverse events (proctitis, cystitis, lymphedema, and ileus) were graded, and the incidences were estimated. RESULTS: Overall, 5-year CSS and RFR did not differ significantly between patients treated with definitive RT (80.4% and 69.7%, respectively) and those treated with postoperative RT (80.6% and 79.1%, respectively). Rates according to clinical stage also did not differ significantly between the two types of treatment. Grades 1-3 adverse events occurred. Grades 2-3 lymphedema and Grades 2-3 ileus, but not Grades 2-3 cystitis, occurred significantly often with postoperative RT. CONCLUSION: Despite no difference in survival or patterns of recurrence, adverse events were significantly more frequent with postoperative RT than with definitive RT for both stages IB-IIA and stage IIB disease.
