Abstract

BACKGROUND: To evaluate tumor responses, event-free survival (EFS), overall survival (OS), and toxicity of chemotherapy, children with neurofibromatosis type 1 (NF1) and progressive low-grade glioma were enrolled into the Children's Oncology Group (COG) A9952 protocol and treated with carboplatin and vincristine (CV). METHODS: Non-NF1 patients were randomized to CV or thioguanine, procarbazine, 1-(2-chloroethyl)-3-cyclohexyl-1-nitrosourea, and vincristine in COG A9952. NF1 patients were assigned to CV only. NF1 patients and non-NF1 patients who were treated with CV were compared with respect to baseline characteristics, toxicity, tumor responses, EFS, and OS. RESULTS: A total of 127 eligible patients with NF1 were nonrandomly assigned to CV: 42 NF1 patients (33%) had events, and 6 (4.7%) died. The 5-year EFS rate was 69%±4% for the CV-NF1 group and 39%±4% for the CV-non-NF1 group (P
