Abstract

Objective: To evaluate treatment outcomes of locally advanced cervical cancer patients who received concurrent weekly carboplatin with radiation therapy.

Methods: Patients with locally advanced cervical cancer who had primary radiation treatment in concurrent with weekly carboplatin (100mg/m(2) or AUC 2) from 1997 to 2008 were identified. Demographic data, chemotherapy cycles, total treatment time, toxicities, and treatment outcomes were recorded.

Results: One hundred and forty-eight patients with stage IIB (50.7%), IIIB (48.0%) and IVA (1.3%) cervical cancer patients were included in the study. Median total treatment time was 53.5 days (range, 45-100 days). Carboplatin was given for a median number of 6 cycles (range, 3-6 cycles). Complete response was achieved in 142 patients (95.9%) while six (4.1%) had persistent diseases. Among the 142 responders, 36 experienced recurrences: pelvic recurrences in seven (4.7%), distant failure in 25 (16.9%), and both pelvic and distant in four (2.7%). The 2-year and 5-year progression-free survival rates were 75.1% and 63.0%, respectively with the corresponding 2-year and 5-year overall survival rates of 81.9% and 63.5%. No grade 3 or 4 hematologic and non-hematologic toxicities were observed during treatment in any patients. Late grade 3-4 gastrointestinal or genitourinary toxicities were 10.1% and 0.7%, respectively.

Conclusion: Concurrent weekly carboplatin with radiation therapy yields high response rate with modest progression-free and overall survivals in locally advanced cervical cancer. The regimen is feasible with minimal toxicities.
