- Abstract
- Objectives: There is no consensus on whether giving adjuvant concurrent chemoradiotherapy (CCRT) is more effective than adjuvant radiotherapy (RT) alone in patients with early stage cervical cancer and intermediate-risk factor(s). The purpose of this study was to evaluate survival difference according to adjuvant treatment in the intermediate-risk group. Methods: From 2000 to 2014, the medical records of patients with stage IB-IIA cervical cancer and a history of radical hysterectomy with pelvic lymph node dissection, followed by pelvic RT at a dose >= 40 Gy were retrospectively reviewed. Among these, 316 patients with one or more intermediate-risk factor(s) and no high-risk factors were included. The criteria defined the intermediate-risk group as those patients with any of the following intermediate-risk factors: lymphovascular space involvement, over one-half stromal invasion, or tumor size >= 4 cm. Results: The median follow-up duration was 70 months (range: 3-203 months). According to adjuvant treatment (adjuvant RT alone vs. adjuvant CCRT), the 5-year recurrence-free survival rates (90.8% vs. 88.9%, p=0.631) and 5-year overall survival rates (95.9% vs. 91.0%, p=0.287) did not show a significant difference in patients with any of the intermediate-risk factors. In multivariate analysis, a distinct survival difference according to adjuvant treatment was not found regardless of the number of risk factors. Conclusion: The present study showed that giving RT together with chemotherapy is not more effective than RT alone for stage IB-IIA cervical cancer patients with intermediate-risk factor(s).
