About
Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. This phase II trial is studying how well topotecan hydrochloride works in treating children with meningeal cancer that has not responded to previous treatment
Full description
PRIMARY OBJECTIVES:
I. Determine the therapeutic activity of intrathecal topotecan, in terms of response rate and time to central nervous system (CNS) progression, in pediatric patients with recurrent or refractory neoplastic meningitis.
II. Determine the safety and toxicity of this regimen in these patients. III. Evaluate the concentration of matrix metalloproteinases (MMPs) in the cerebrospinal fluid (CSF) of these patients.
OUTLINE: Patients are stratified according to disease type (acute lymphoblastic leukemia vs. other leukemia/lymphoma vs medulloblastoma vs other solid tumors). (Recurrent CNS acute lymphoblastic leukemia stratum only open to accrual as of 11/30/04)
INDUCTION: Patients receive topotecan hydrochloride intrathecally (IT) over 5 minutes twice weekly for 6 weeks.
CONSOLIDATION: Beginning 1 week after completion of induction, patients receive topotecan hydrochloride IT over 5 minutes weekly for 4 weeks in the absence of disease progression or unacceptable toxicity.
MAINTENANCE: Beginning 2 weeks after completion of consolidation, patients receive topotecan hydrochloride IT over 5 minutes twice monthly for 4 months and then monthly through year 1.
After completion of study treatment, patients are followed up monthly for 3 months, every 3 months for 1 year, every 6 months for 3 years, and then annually thereafter.
PROJECTED ACCRUAL: A total of 14-77 patients will be accrued for this study.

Definition of meningeal disease:
Leukemia/lymphoma (including acute lymphoblastic leukemia)
Solid tumors (including medulloblastoma)
No clinical evidence of obstructive hydrocephalus or compartmentalization ofCSF flow as documented by radioisotope indium In 111 or technetium Tc 99 DTPAflow study
No ventriculoperitoneal or ventriculoatrial shunt unless:
No impending cord compression, CNS involvement requiring local radiotherapy(e.g., optic nerve), or isolated bulky ventricular or leptomeningeal basedlesions

At least 8 weeks
Platelet count greater than 40,000/mm^3 (transfusions allowed)
Bilirubin less than 2.0 mg/dL
SGPT less than 5 times normal
Creatinine less than 1.5 mg/dL

Negative pregnancy test
Fertile patients must use effective contraception
No significant illness (e.g., uncontrolled infection, except HIV [i.e., AIDS-related lymphomatous meningitis])
Prior immunotherapy allowed and recovered
At least 3 weeks since systemic CNS directed chemotherapy (6 weeks for nitrosoureas) and recovered
At least 1 week since prior intrathecal (IT) chemotherapy (2 weeks for cytarabine [liposomal])
No prior IT chemotherapy on days -14 to -7 before study entry unless evidence of disease progression (e.g., increasing WBC and percentage blasts in patients with leukemia/lymphoma or increased leptomeningeal enhancements in patients with solid tumors) (Recurrent CNS acute lymphoblastic leukemia stratum only open to accrual as of 11/30/04)
Concurrent chemotherapy to control systemic disease or bulk CNS disease allowed if the systemic chemotherapy is not a phase I study agent that significantly penetrates the CSF (e.g., high-dose systemic methotrexate [greater than 1 g/m^2], thiotepa, high-dose cytarabine, temozolomide, IV mercaptopurine, nitrosourea, or topotecan) or an agent known to have serious unpredictable CNS side effects
Concurrent dexamethasone or prednisone allowed if part of a systemic chemotherapy regimen
See Disease Characteristics

At least 7 days since prior investigational drug
No other concurrent investigational agents
No concurrent therapy (IT or systemic) for leptomeningeal disease
No other concurrent systemic agents that significantly penetrate the blood-brain barrier
