PRIMARY OBJECTIVES:~I. Compare the efficacy of neoadjuvant and adjuvant fenretinide vs adjuvant fenretinide alone, in terms of 6-month progression-free survival, in patients with recurrent glioblastoma multiforme undergoing surgical resection II. Correlate the serum and glioma tissue pharmacology of this drug with clinical response in patients treated with these regimens.~III. Determine whether this drug induces apoptosis in glioma tissue in patients treated with these regimens.~IV. Correlate the apoptotic index with tissue and serum concentration and clinical response in patients treated with these regimens.~V. Compare radiological response, overall survival, and unexpected toxicity in patients treated with these regimens.~OUTLINE: This is a randomized study. Patients are randomized to 1 of 2 treatment arms.~Arm I: Patients receive neoadjuvant oral fenretinide twice daily for 1 week and then undergo surgical resection.~Arm II: Patients undergo surgical resection.~Beginning two weeks after surgery, all patients receive adjuvant oral fenretinide twice daily on weeks 1 and 4. Courses repeat every 6 weeks in the absence of disease progression or unacceptable toxicity.~PROJECTED ACCRUAL: A total of 21-46 patients (10-23 per treatment arm) will be accrued for this study within 7-46 months.
This randomized phase II trial is studying how well neoadjuvant and adjuvant fenretinide works compared to adjuvant fenretinide alone in treating patients who are undergoing surgical resection for recurrent glioblastoma multiforme. Chemotherapy drugs, such as fenretinide, work in different ways to stop tumor cells from dividing so they stop growing or die. Giving chemotherapy before surgery may shrink the tumor so that it can be removed. Giving chemotherapy after surgery may kill any remaining tumor cells. It is not yet known whether neoadjuvant and adjuvant fenretinide is more effective than adjuvant fenretinide alone
