Abstract
The authors investigated the results of PCV chemotherapy within a cohort of 24 patients treated within the EORTC study 26971 on temozolomide chemotherapy in recurrent oligodendroglioma. The genotype of the tumors was assessed with fluorescent in situ hybridization with locus specific probes for the region 1p36. Four of the 24 patients responded (17%). Fifty percent of patients were still free from progression at 6 months and 21% were free from progression at 12 months. Although a clear relation existed between loss of 1p and response to temozolomide chemotherapy, this relation was absent in salvage PCV chemotherapy.
