Brief Summary: RATIONALE Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die Combining more than one drug may kill more tumor cells It is not yet known whether giving procarbazine alone or with isotretinoin is more effective for recurrent primary malignant glioma
PURPOSE Randomized phase III trial to compare the effectiveness of procarbazine alone or with isotretinoin in treating patients with recurrent primary malignant gliomas
Detailed Description: OBJECTIVES I Determine whether the combination of isotretinoin and procarbazine can improve time to progression and survival compared to procarbazine alone in patients with recurrent malignant gliomas II Document the toxicity of these two regimens in these patients
OUTLINE This is a randomized multicenter study Patients are randomized to receive procarbazine alone or in combination with isotretinoin Arm I Patients receive oral procarbazine once daily on days 1-14 every 28 days Oral isotretinoin is administered every 12 hours on days 15-28 every 28 days Patient receive 6 courses of combined therapy then continue with oral isotretinoin alone on days 15-28 of each 28 day course until disease progression or unacceptable toxicity Arm II Patients receive procarbazine by mouth once daily on days 1-14 followed by 2 weeks of rest Patients receive a total of 6 courses of treatment in the absence of disease progression and unacceptable toxicity Patients are followed until death
PROJECTED ACCRUAL This study will accrue a total of 194 patients 97 per treatment group
