摘要

Background: Adding bevacizumab to chemotherapy for recurrent, persistent or metastatic cervical cancer significantly improved overall survival (primary endpoint), progression-free survival and overall response rate in the randomized Phase III GOG-0240 trial. However, data for bevacizumab-containing therapy are scarce in Japanese patients with advanced cervical cancer. Methods: The primary objective of the single-arm multicenter Phase II JO29569 study was to evaluate the tolerability of paclitaxel (135 mg/m(2) over 24 h or 175 mg/m(2) over 3 h), cisplatin (50 mg/m(2)) and bevacizumab (15 mg/kg), administered every 3 weeks until disease progression or unacceptable toxicity in Japanese patients with stage IVB, persistent or recurrent cervical cancer. Results: The seven treated patients received a median of nine (range 7-12) bevacizumab cycles and six (range 4-12) chemotherapy cycles. None of the predefined adverse events occurred during the tolerability evaluation period. The most common all-grade adverse events were alopecia, hypertension, decreased appetite, nausea and peripheral sensory neuropathy. There were no cases of fistula. The most common grade >= 3 adverse events were hypertension, neutrophil count decreased and neutropenia. Only one patient experienced febrile neutropenia. The overall response rate was 86% (95% confidence interval, 42-100%), including a complete response in one patient. At data cutoff, disease had progressed in one patient; bevacizumab therapy was ongoing in the remaining six. Conclusions: According to the specified primary objective, a regimen of cisplatin, paclitaxel and bevacizumab was tolerable in Japanese patients and demonstrated encouraging activity in this small single-arm study. Further study is warranted to confirm the safety and effectiveness of bevacizumab in Japanese patients with cervical cancer.
