Efficacy and safety of bevacizumab in Turkish patients with metastatic and recurrent cervical cancer

Objective: To evaluate the efficacy of bevacizumab a monoclonal, antivascular endothelial growth factor antibody in combination with cytotoxic chemotherapy in Turkish patients with recurrent and metastatic cervical cancer. Materials and Methods: Data of 64 patients with metastatic or recurrent cervical cancer, receiving bevacizumab with first-line cisplatin or carboplatin and paclitaxel chemotherapy between 2013 and 2017 were retrospectively evaluated. Results: The mean age of the patients was 49 years (range, 28-68), the median follow-up time was 12 months (range, 2-53), the median progression-free survival (PFS) was eight months, and the median overall survival (OS) was 23 months. All 64 patients received a median of 6 (range, 1-12) bevacizumab and 6 (range, 2 12) chemotherapy cycles. The chemotherapy regimens used with bevacizumab were cisplatin and paclitaxel in 31 (48%) and carboplatin and paclitaxel in 33 (52%) patients. The survival in patients treated with bevacizumab and cisplatin plus paclitaxel was better-particularly in patients with no previous cisplatin-based radiosensitizer therapy-than those treated with carboplatin, paclitaxel, and bevacizumab (p=0.023). The bevacizumab dose was 7.5 mg/kg in 30 patients (47%) and 15 mg/kg in 34 patients (53%) every 21 days. No significant difference was reported in the OS and the PES between the two groups. While the most common all-grades adverse events were nausea, neutropenia, anemia, and peripheral sensory neuropathy, the most common grade >= adverse events were neutropenia, anemia, and peripheral sensory neuropathy. Conclusion: Adding bevacizumab to platinum and paclitaxel chemotherapy in a case of metastatic or recurrent cervical cancer is an effective and tolerable treatment for Turkish patients.
