Abstract
- Objectives We aimed to evaluate whether carboplatin has a comparable efficacy with cisplatin as part of weekly concurrent chemoradiotherapy for cervical cancer (Car-RT vs. Cis-RT). Methods A literature search was conducted and both prospective and retrospective studies that evaluated the efficacy of Car-RT for cervical cancer were included. The primary endpoints were complete response (CR) rate, progression-free survival (PFS)/disease-free survival (DFS), overall survival (OS), reported as odds ratios (ORs) and 95% confidence intervals (CIs). The estimated CR rate and survival of patients treated with Car-RT were pooled. Acute toxicity was also summarized. Results Twelve studies consisting of 1698 patients were eligible for meta-analysis. A lower CR rate (OR, 0.53; 95% CI, 0.34–0.82, I2 = 0%) and a trend toward poorer 3-year PFS/DFS (OR, 0.71; 95% CI, 0.49–1.02, I2 = 0%) and 3-year OS (OR, 0.70; 95% CI, 0.46–1.05, I2 = 36%) were found in Car-RT compared with Cis-RT. For the Car-RT groups, the pooled overall CR rate was 81% (95% CI 0.74–0.89). The pooled 3-year PFS/DFS rate was 64% (95% CI 0.52–0.78). The pooled 3-year OS rate was 73% (95% CI 0.62–0.87). Acute toxic events ≥ grade 3 were infrequent in the Car-RT groups. Conclusions Car-RT showed a poorer tumor response and a trend toward inferior survival compared with Cis-RT in the treatment of cervical cancer. However, this evidence was limited by the imbalance among studies. Due to the encouraging efficacy and low toxicity, carboplatin is a suitable concurrent agent for patients with contraindications to cisplatin.
