About

RATIONALE: Drugs used in chemotherapy, such as trimetrexate glucuronate and leucovorin, use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells.

PURPOSE: This phase II trial is studying how well combination chemotherapy works in treating children with recurrent acute lymphoblastic leukemia, recurrent osteosarcoma, or refractory non-Hodgkin's lymphoma.

Full description

OBJECTIVES:

• Determine the efficacy of trimetrexate glucuronate with leucovorin calcium rescue in children with recurrent acute lymphoblastic leukemia, recurrent osteogenic sarcoma, or refractory non-Hodgkin's lymphoma resistant to methotrexate.
• Evaluate the toxicity of this treatment regimen in this patient population.

OUTLINE: Patients are stratified according to disease (acute lymphocytic leukemia, non-Hodgkin's lymphoma vs osteogenic sarcoma).

Patients receive trimetrexate glucuronate orally or IV every 12 hours on days 1-21 and oral leucovorin calcium every 12 hours on days 1-24. Treatment repeats every 4 weeks. Patients with stable or responsive disease may receive up to 4 courses of therapy.

PROJECTED ACCRUAL: A total of 25 patients will be accrued for this study within 2 years.

Enrollment: 25 estimated patients

Sex: All

Ages: Under 21 years old

Volunteers: No Healthy Volunteers
