Phase II trial to study the effectiveness of rebeccamycin analogue in treating children who have solid tumors or non-Hodgkin's lymphoma. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die.

OBJECTIVES:

I. Determine the response in children with solid tumors or non-Hodgkin's lymphoma treated with rebeccamycin analogue.

II. Determine and maintain a plasma concentration of at least 5 µg/mL of this drug in these patients.

III. Determine the toxicity of this drug in these patients. IV. Determine the pharmacokinetics of this drug in these patients.

OUTLINE: This is a multicenter study.

Patients with solid tumors are stratified according to tumor histology (neuroblastoma vs Ewing's sarcoma [closed to accrual as of 5/19/03]/peripheral primative neuroectodermal tumor [PNET] vs osteosarcoma [closed to accrual as of 5/19/03] vs rhabdomyosarcoma vs non-Hodgkin's lymphoma vs other solid tumors). Patients with CNS tumors are stratified according to tumor histology (medulloblastoma/PNET vs ependymoma vs brainstem glioma vs other CNS tumors).

Patients receive rebeccamycin analogue IV over 1 hour on day 1. Treatment continues every 21 days for a total of 16 courses in the absence of disease progression or unacceptable toxicity.

Patients are followed monthly for 1 year, every 2 months for 2 years, every 6 months for 1 year, and then annually thereafter.
