详细描述
The purpose of this study is to determine the qualitative and quantitative toxicity of intrathecal topotecan, a topoisomerase I inhibitor, in patients with meningeal malignancies refractory to conventional therapy (radiation therapy and chemotherapy). A safe dose of topotecan that can be recommended for intrathecal administration in subsequent phase II studies will be established in a limited dosage escalation schedule. The CSF pharmacokinetics of intrathecal topotecan will also be studied. Topotecan will be administered intrathecally on a bi-weekly basis for four to six weeks, followed by weekly administration for 1 month, twice monthly administration for four months and then monthly IT administration.

- •CSF leukemic cell count at least 5 per cubic millimeter with evidence of blast cells on cytospin or cytology required for leukemia and lymphoma patients.
- •Tumor cells on cytospin or cytology or measurable meningeal disease on CT or MRI required for patients with solid tumors.
- •No clinical evidence of obstructive hydrocephalus or compartmentalization of the CSF flow as documented by indium-111- or technetium-99-DPTA flow study.
- •PRIOR/CONCURRENT THERAPY:
- •At least 1 week since CNS therapy.
