Objective: A multicenter phase II trial was conducted to assess the efficacy and toxicity of concurrent chemoradiotherapy (CCRT) with weekly cisplatin (CDDP) and paclitaxel (PTX) in patients with locally advanced uterine cervical cancer.
Methods: Patients with FIGO stage III-IVA uterine cervical cancer without para-aortic lymphadenopathy were enrolled. Patients received definitive radiotherapy (RT) consisting of external beam whole-pelvic RT and high-dose-rate intracavitary brachytherapy. The cumulative linear quadratic equivalent dose was 62-65Gy prescribed at point A. weekly CDDP at 30mg/m(2) and PTX at 50mg/m(2) were administered concurrently with RT for ≥5 courses.
Results: Sixty-eight of the 70 registered patients were eligible. The complete response rate was 76.5% (95% confidence interval [CI], 66.4-86.6%). With a median follow-up of 27months (range, 7.9-33.5), the 2-year cumulative progression-free survival and the 2-year cumulative overall survival rates were 83.8% (95% CI, 75.1-92.6%) and 92.7% (95% CI, 86.4-98.9%), respectively. The pelvic cumulative disease progression-free and the 2-year cumulative distant metastasis rates were 89.6% (95% CI, 82.3-96.9%) and 13.2% (95% CI, 5.2-21.3%), respectively. The 2-year cumulative late complication rates were 25% for all grades, 13.2% for grade 1, 5.9% for grade 2, 2.9% for grade 3, and 2.9% for grade 4.
Conclusions: For locally advanced cervical cancer, CCRT with weekly CDDP 30mg/m(2) and PTX at 50mg/m(2) demonstrated favorable antitumor activity, and was feasible and safe with respect to the protocol-specified serious adverse reactions and events. Evaluation of this regimen in phase III trials is warranted.
