Abstract
We evaluated the efficacy of temozolomide TMZ or lomustine CCNU in combination with 6thioguanine capecitabine and celecoxib for the treatment of recurrent highgrade glioma Fortythree patients with recurrent glioblastoma and 31 patients with recurrent anaplastic glioma AG were enrolled in this openlabel noncomparative study Patients previously treated with TMZ received CCNU while all others received TMZ all patients received 6thioguanine capecitabine and celecoxib Endpoints were 12month progressionfree survival PFS for patients with AG 6month PFS for patients with glioblastoma duration of PFS and MRIbased objective response rates Results from the TMZ and CCNU treatment arms were combined in the final analysis because there was no statistically significant difference between them Thirtyeight patients with glioblastoma were treated with the lomustinebased regimen and five received the TMZbased regimen For the 43 glioblastoma patients the objective response rate was 12 and 33 had stable disease the 6month PFS was 14 and median overall survival 32 weeks For the 31 AG patients the combined objective response rate was 26 and 42 had stable disease the 12 month PFS was 44 Treatment was reasonably well tolerated with hematological toxicity common and more frequent with CCNU than TMZ The combination therapy with 6thioguanine capecitabine and celecoxib plus CCNU or TMZ does not appear to be more effective than other alkylating agent schedules for patients with recurrent glioblastoma The combination however is promising for patients with recurrent highgrade AG
