2 Background: AOD are chemotherapy-sensitive tumors especially if 1p/19q co-deleted. Between 1995 and 2002 the EORTC Brain Tumor Group conducted a prospective phase III study on adjuvant procarbazine, CCNU and vincristine chemotherapy (PCV) in AOD. We now present long-term follow-up. Methods: Patients (pts) with locally diagnosed newly diagnosed AOD were randomized between radiotherapy (RT, 33 x 1.8 Gy) and the same RT followed by 6 cycles of standard PCV (RT/PCV). Primary endpoints were overall survival (OS) and progression-free survival (PFS). 1p/19q status, IDH status and MGMT promoter methylation were determined in 300, 167, and 186 pts respectively. Results: Between 1996 and 2002, 368 pts were included. At the time of analysis 281 pts (76.4%) had died. Median PFS after RT/PCV was significantly longer compared to RT alone (24.3 months versus 13.21 months, hazard ratio [HR] 0.66, [95% confidence interval (95% CI) 0.52, 0.83]). More RT arm patients received chemotherapy at progression (75% vs 53%). Median OS was also significantly prolonged in the RT/PCV arm (42.3 months vs 30.6 months for the RT arm, HR 0.75 [95% CI 0.60, 0.95]). 1p/19q co-deleted patients (n = 76) treated with RT/PCV had improved OS compared to RT arm pts (median OS not reached vs 113 months; HR 0.54, p = 0.0487). In the 224 patients without 1p/19q co-deletion the difference in OS was non-significant (OS RT/PCV arm 25 months vs 22 months in the RT arm, HR 0.82, p = 0.18; test for interaction p = 0.22). There was a slight trend towards improved OS in MGMT methylated and IDH mutated tumors versus unmethylated and IDH wild type tumors (Table). Conclusions: The addition of PCV to RT increases PFS and OS in AOD. Pts with 1p/19q co-deletion appear to benefit most from the addition of PCV, with a trend for improved OS in pts with MGMT methylation and IDH mutations. [Table: see text]

Purpose Anaplastic oligodendroglioma are chemotherapy-sensitive tumors. We now present the long-term follow-up findings of a randomized phase III study on the addition of six cycles of procarbazine, lomustine, and vincristine (PCV) chemotherapy to radiotherapy (RT). Patients and Methods Adult patients with newly diagnosed anaplastic oligodendroglial tumors were randomly assigned to either 59.4 Gy of RT or the same RT followed by six cycles of adjuvant PCV. An exploratory analysis of the correlation between 1p/19q status and survival was part of the study. Retrospectively, the methylation status of the methyl-guanine methyl transferase gene promoter and the mutational status of the isocitrate dehydrogenase (IDH) gene were determined. The primary end points were overall survival (OS) and progression-free survival based on intent-to-treat analysis. Results A total of 368 patients were enrolled. With a median follow-up of 140 months, OS in the RT/PCV arm was significantly longer (42.3 v 30.6 months in the RT arm, hazard ratio [HR], 0.75; 95% CI, 0.60 to 0.95). In the 80 patients with a 1p/19q codeletion, OS was increased, with a trend toward more benefit from adjuvant PCV (OS not reached in the RT/PCV group v 112 months in the RT group; HR, 0.56; 95% CI, 0.31 to 1.03). IDH mutational status was also of prognostic significance. Conclusion The addition of six cycles of PCV after 59.4 Gy of RT increases both OS and PFS in anaplastic oligodendroglial tumors. 1p/19q-codeleted tumors derive more benefit from adjuvant PCV compared with non–1p/19q-deleted tumors.
