RATIONALE: Antineoplastons are naturally-occurring substances that may also be made in the laboratory. Antineoplastons may inhibit the growth of cancer cells. PURPOSE: This phase II trial is studying how well antineoplaston therapy works in treating patients with residual or recurrent anaplastic astrocytoma.

Study summary:

OBJECTIVES: - Determine the objective response rate in patients with anaplastic astrocytoma treated with antineoplastons A10 and AS2-1 after subtotal resection. - Assess tolerance to and side effects of this regimen in these patients. OUTLINE: This is an open-label study. Patients receive gradually escalating doses of antineoplaston A10 and antineoplaston AS2-1 IV 6 times daily until the maximum tolerated dose is reached. Treatment continues for at least 2 months in the absence of unacceptable toxicity or disease progression. Patients achieving stable disease or partial response may continue treatment. Patients achieving complete response (CR) continue treatment for an additional 8 months after CR. Tumors are measured at 1 month, every 1-2 months for 2 years, every 3 months for the third year, every 4 months for the fourth year, every 6 months for the fifth year, and then annually thereafter. PROJECTED ACCRUAL: A total of 20-40 patients will be accrued for this study.
