Objective The aim of this study was to compare the efficacy of nedaplatin-based concurrent chemoradiotherapy (CCRT) with that of cisplatin-based CCRT in patients with cervical cancer. Methods The medical records of patients with cervical cancer who had undergone CCRT between 2003 and 2007 were retrospectively reviewed. Of these, 129 patients were treated postoperatively with CCRT ( n  = 52) or primary CCRT ( n  = 77). A total of 29 patients were treated with nedaplatin-based postoperative CCRT and 23 patients were treated with cisplatin-based postoperative CCRT. A total of 28 patients were treated with nedaplatin-based postoperative CCRT, and 49 patients were treated with cisplatin-based postoperative CCRT. Progression-free survival (PFS) and overall survival (OS) were compared between the treatment groups. Results With postoperative CCRT, there were no significant differences in recurrence rate ( P  = 1.0000), PFS (log-rank: P  = 0.8503), and OS (log-rank: P  = 0.8926) between the two treatment groups. With primary CCRT, there were no significant differences in PFS (log-rank: P  = 0.7845) and OS (log-rank: P  = 0.3659). The frequency of acute toxicity was not significantly different between the cisplatin-based postoperative CCRT group and the nedaplatin-based postoperative CCRT group. Conclusions Nedaplatin-based postoperative CCRT is an effective and well-tolerated regimen for both early-stage and advanced-stage cervical cancer patients.
