Phase II trial of paclitaxel and nedaplatin in patients with advanced/recurrent uterine cervical cancer: A Kansai Clinical Oncology Group study

Abstract Objective A multicenter phase II trial was conducted to evaluate the activity and toxicity of paclitaxel and nedaplatin (cis-diammineglycolatoplatonum) in patients with advanced/recurrent uterine cervical cancer. Methods Patients were required to have measurable disease. Histologic confirmation of the primary diagnosis as uterine cervical cancer was mandatory. The treatment consisted of paclitaxel 175mg/m 2 over 3hours and nedaplatin 80mg/m 2 intravenously over 1hour on day 1 every 28days until progressive disease or adverse effects prohibited further therapy. Results Fifty patients were enrolled into the study protocol from October 2007 to February 2010. 45 patients(90%) were eligible for assessment of response (RECIST version 1.0) to treatment; 31 patients (62%) received prior radiotherapy and 23 patients (46%) received prior chemotherapy. The overall response rate was 44.4% (11 complete responses and 8 partial responses) with 22.2% of patients having stable disease. Grades 3 or 4 adverse events (NCI-CTCAE ver 3) included neutropenia ( n =16, 32.7%), febrile neutropenia ( n =1, 2.0%), anemia ( n =9, 18.4%), but there was no significant thrombocytopenia. Non-hematologic toxicity was generally not serious and without a dominant pattern. The median progression-free survival was 7.5months (95% C.I., 5.7, 9.4) and overall survival was 15.7months (95% C.I., 9.4, 21.9). Conclusions Paclitaxel 175mg/m 2 and nedaplatin 80mg/m 2 intravenously on day 1 every 28days in patients with advanced/recurrence uterine cervical cancer demonstrated easy administration, favorable antitumor activity, and the toxicity profile of this regimen would be decreased compared with cisplatin-containing combinations. Evaluation of this regimen in phase III trials is warranted.
