Phase I/II study of intravenous nedaplatin and intraarterial cisplatin with transcatheter arterial embolization for patients with locally advanced uterine cervical carcinoma

Abstract

BACKGROUND. Nedaplatin, a platinum analog with less renal toxicity and similar efficacy for cervical carcinoma, recently has been shown to have a synergistic effect on cervical carcinoma lines in combination with cisplatin. To determine the clinical efficacy of this combination in patients with cervical carcinoma, the authors conducted a Phase I/II study of intravenous nedaplatin and intraarterial cisplatin combined with transcatheter arterial embolization (TAE). METHODS. Eligibility criteria were as follows: cervical carcinoma (Stages IB2-IV; International Federation of Gynecology and Obstetrics), 16-70 years of age, performance status between 0 and 2, and adequate bone marrow, renal, and hepatic function. Nedaplatin (40-70 mg/m2) was administered intravenously on Day 1 followed by intraarterial administration of cisplatin (70 mg/m2) on Day 3 via both uterine arteries by using the Seldinger method. This then was followed by TAE. This course of treatment was repeated every 3 weeks for 3 cycles. RESULTS. Patient data were as follows: Age 37-68 (median, 55 years) and Stages IB2:4, IIA:3, IIB:2, IIIA:1, IIIB:3, IVA:2 carcinoma. The response to therapy was defined by magnetic resonance imaging as follows: partial response in 60% (9 of 15) of patients, complete response in 40% (6 of 15) of patients, and an overall response rate of 100% (95% confidence interval, 78-100%). Myelosuppression was manageable. Grade 3/4 renal toxicity was observed in 2 patients who received 70 mg/m2 of nedaplatin. Thirteen patients received radical hysterectomy, 1 patient received lymph node sampling, and 11 patients received adjuvant radiotherapy or chemotherapy. CONCLUSIONS. The maximum tolerable dose was 70 mg/m2 nedaplatin, and the dose-limiting toxicity was renal toxicity. The recommended dose was 60 mg/m2 nedaplatin intravenously followed by 70 mg/m2 cisplatin intraarterially. Intravenous nedaplatin followed by intraarterial cisplatin with TAE appears to be very effective for locally advanced cervical carcinoma. © 2001 American Cancer Society.
