Outcome and prognostic factors in cervical cancer patients treated with surgery and concurrent chemoradiotherapy: a retrospective study

BACKGROUND: The objective of this study is to analyze the treatment outcome and secondary reactions in 98 patients with stage I–III cervical carcinoma who underwent postoperative radiotherapy. METHODS: From 2006 to 2014, 98 patients with stage I–III cervical carcinoma were treated with postoperative radiotherapy. The major histological type, found in 92.86% of the patients (91 cases), was squamous cell carcinoma. Patients were staged according to the 2002 TNM guidelines. The postoperative radiotherapy methods included two-field irradiation (16 patients, 16.32%), four-field box irradiation (16 patients, 16.32%), and intensity-modulated radiotherapy (IMRT; 66 patients, 67.36%). The survival rates were represented using Kaplan-Meier curves, and prognosis analyses were performed using Cox multivariate analyses. RESULTS: The 5-year overall survival and progression-free survival rates were 82.0 and 76.0%, respectively. Only one patient (1.02%) developed a grade 3 acute radiation enteritis, while grade 3 and 4 myelosuppression was noted in 17 patients (17.35%) and one patient (1.02%), respectively. Multivariate analyses showed that anemia before radiotherapy and tumor size were predictors of the OS (P = 0.008, P = 0.045) rates. CONCLUSIONS: Postoperative radiotherapy for patients with risk factors of cervical cancer procured good efficacy levels with mild side effects. Anemia and tumor size were important OS predictors.
