Combination chemotherapy with carmustine and cisplatin followed by procarbazine, lomustine, and vincristine for adult high-grade astrocytoma.
BACKGROUND
We have reported that carmustine (BCNU) and cisplatin administered before, during, and after radiotherapy did not improve the survival of patients with high-grade astrocytomas and were associated with more serious toxicities than radiotherapy plus BCNU. In an attempt to improve survival, we studied a combination regimen procarbazine, lomustine, and vincristine (PCV) after radiotherapy in addition to BCNU and cisplatin during radiotherapy.


METHODS
From 1994 through 1998, 42 patients were enrolled in the study. Of these, 20 had glioblastoma multiforme and 22 had anaplastic astrocytoma. The patients had a median age of 48.5 years. All patients had subtotal or total resection, or biopsy as the initial procedure. Then, all patients were treated with BCNU and cisplatin concurrently during radiotherapy followed by PCV after radiotherapy.


RESULTS
The median time to follow up for survivors was 13.8 months (range, 1.7-108.2 months). The median time to tumor progression was 7.2 months (range, 0-88.7 months) and median survival time was 13.3 months (range, 1.7-88.7 months). The only factor that had a conventionally significant effect on the overall survival was resectability. Patients who had received subtotal/total resection had a longer median survival compared with patients who had received biopsy only (18.0 vs. 9.5 months). This combined modality treatment program was associated with reversible grade 3 to 4 hematological toxicity in 10 patients, with grade 3 ototoxicity in one patient and grade 2 neurotoxicity in one patient.


CONCLUSIONS
A combination of BCNU and cisplatin with cranial irradiation followed by PCV was moderately toxic and appeared to offer no obvious survival advantages compared with radiotherapy plus BCNU and cisplatin alone.
