Drugs currently available for intrathecal administration are cleared rapidly from the CSF. DepoCyt is a slow-release formulation of cytarabine that maintains cytotoxic concentrations of free cytarabine in the CSF for > 14 days following a single injection. DepoCyt was administered to 110 patients with a diagnosis of neoplastic meningitis based on either a positive CSF cytology (76) or neurologic and CT or MRI scan findings sufficient to document neoplastic meningitis (34). Patients were treated with DepoCyt 50 mg every 2 weeks for 1 month of induction therapy by either lumbar puncture (LP) or intraventricular (IVT) injection. Patients without neurologic progression were candidates to receive an additional 3 months of consolidation therapy. All patients received dexamethasone 4 mg BID on days 1-5 of each cycle. Median time to neurologic progression was 55 days; median overall survival was 95 days. Among the 76 patients with a positive CSF cytology at baseline, 70 were evaluable for response, and of this group19 (27%) attained the criteria for response (cytologic response in the absence of neurologic progression). The most important adverse events were headache and arachnoiditis. When drug-related, these were largely low grade, transient, and reversible. Drug-related grade 3 headache occurred on 4% of cycles; grade 3 or 4 arachnoiditis occurred on 6% of cycles. No cumulative toxicity was observed. DepoCyt injected once every 2 weeks produced a response-rate comparable to that previously reported for methotrexate given twice a week. The once in every 2-week-dosing interval offers an advantage over conventional schedules (2-3 doses/week) used for other agents available for intrathecal injection.
