OBJECTIVE: This multicenter phase II Japanese Gynecologic Oncology Group study (JGOG1067) was designed to evaluate the efficacy and safety of postoperative chemotherapy in patients with node-positive cervical cancer.
METHODS: Patients with stage IB-IIA squamous cervical cancer who underwent radical hysterectomy and were confirmed to have pelvic lymph node metastasis were eligible for this study. The patients postoperatively received irinotecan (CPT-11; 60mg/m2 intravenously on days 1 and 8) and nedaplatin (NDP; 80mg/m2 intravenously on day 1). Chemotherapy administration commenced within 6weeks after surgery and was repeated every 28days for up to 5cycles. The primary endpoint of this study was the 2-year recurrence-free survival (RFS) rate. The secondary endpoints were the 5-year overall survival (OS) rate, 5-year RFS rate, and adverse events such as complications of chemotherapy and lower-limb edema.
RESULTS: Sixty-two patients were analyzed according to our protocol, among whom 55 (88.7%) completed 5cycles of scheduled treatment. The median follow-up period was 66.1months (range, 16.8-96.6months). The 2-year and 5-year RFS rates were 87.1% (95% confidence interval [CI]: 75.9-99.3) and 77.2% (95% CI: 64.5-85.8), respectively. Fourteen patients (22.5%) experienced recurrence during the follow-up period, 8 of whom died of the disease. The 5-year OS rate in this study was 86.5% (95% CI: 74.8-93.0). Only 9.7% of the patients experienced lymphedema in their legs.
CONCLUSION: Postoperative chemotherapy without radiotherapy was found to be very effective in high-risk patients with node-positive cervical cancer.
