Feasibility and safety of carboplatin plus paclitaxel as neoadjuvant chemotherapy for locally advanced cervical cancer: a pilot study.

The aim of this study is to evaluate the efficacy and safety of the combination of carboplatin and paclitaxel as neoadjuvant chemotherapy (NACT) in patients affected by locally advanced cervical cancer. Between June 2007 and May 2012, all patients with a diagnosis of locally advanced cervical cancer (IB2–IIB) were eligible for this protocol. All patients have received 3 cycles of carboplatin (AUC6) and paclitaxel 175 mg/mq in neoadjuvant setting. The NACT-induced toxicity and the response to treatment were evaluated according to the World Health Organization (WHO) criteria. After NACT, all patients with complete or partial response were submitted to classical radical hysterectomy type III or C2, according to different classifications, and were submitted to four adjuvant cycles of platinum-based chemotherapy. The primary endpoints of the study were to evaluate the efficacy and feasibility of carboplatin regimen. Thirty-five patients with locally advanced cervical cancer were considered. A total of 23 patients completed 3 cycles of NACT. The overall clinical response rate after NACT was 78.3% including 43.5% (n = 10) with complete response, 34.8% (n = 8) with partial response, 17.4% (n = 4) with stable disease and 4.3% (n = 1) of those who suffered disease progression. The most common toxicity was haematologic, nausea/vomiting and neuropathy with grades 1 and 2 and occurred in 56.5, 56.5 and 17.4%, respectively. No renal toxicity was registered. Our results suggest that carboplatin is a well-tolerated drug with a response rate similar to standard cisplatin. Then, it represents, in neoadjuvant setting, a valid alternative in patients affected by locally advanced cervical cancer.
