Summary
Brief summary
This randomized phase III trial is studying low-dose vincristine to see how well it works
compared with high-dose vincristine when given together with different combination
chemotherapy regimens in treating young patients with intermediate-risk relapsed B-cell acute
lymphoblastic leukemia. Drugs used in chemotherapy work in different ways to stop the growth
of cancer cells, either by killing the cells or by stopping them from dividing. Giving more
than one drug (combination chemotherapy) and giving the drugs in different ways and different
doses may kill more cancer cells..
