• PRIOR CONCURRENT THERAPY:
• See Disease Characteristics
• More than 4 weeks since prior surgery for recurrent or progressive disease and recovered
• More than 28 days since prior major surgical procedure or open biopsy
• At least 4 weeks since prior cytotoxic therapy (6 weeks for nitrosoureas)
• At least 2 weeks since prior vincristine
• At least 3 weeks since prior procarbazine hydrochloride
• At least 1 week since prior noncytotoxic agents (e.g., interferon, tamoxifen, thalidomide, or isotretinoin)
