Patients were 20 to 70 years of age and had Eastern Cooperative Oncology Group performance status of 0 to 1. The radiotherapy protocol consisted of whole-pelvis external beam radiotherapy and HDR-ICBT. The cumulative linear quadratic equivalent dose (EQD2) was 62 to 65 Gy prescribed at point A. Cisplatin was administered weekly at a dose of 40 mg/m2 for 5 courses.Results Between March 2008 and January 2009, 72 patients from 25 institutions were enrolled, and 71 patients were eligible and evaluable for compliance and severe toxicity. The median age of the patients was 57 years (range, 32–70 years). Sixty-five patients (92%) received the planned 5 courses of chemotherapy. Four patients had cisplatin dose reduction according to the protocol. Radiotherapy was completed per protocol in 68 patients (96%). Median overall treatment time was 50 days (range, 37–66 days). The following grade 3 or 4 acute adverse events were observed: neutropenia in 31 patients (44%), anemia in 10 patients (14%), diarrhea in 4 patients (6%), and anorexia in 3 patients (4%).Conclusions Concurrent chemoradiotherapy with HDR-ICBT and standard weekly delivery of cisplatin was feasible with acceptable toxicity in Japanese patients with cervical cancer.
