Combination Chemotherapy and Radiation Therapy in Treating Patients With Acute Lymphoblastic Leukemia That Has Relapsed in the CNS or Testes

Official Title:

Treatment of Late Isolated Extramedullary Relapse From Acute Lymphoblastic Leukemia (ALL) (Initial CR1≥ 18 Months)

Summary

RATIONALE: Drugs used in chemotherapy work in different ways to stop cancer cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage cancer cells. Giving combination chemotherapy together with radiation therapy may kill more cancer cells.

PURPOSE: This clinical trial is studying how well giving chemotherapy together with radiation therapy works in treating patients with acute lymphoblastic leukemia that has relapsed in the CNS and/or testes.

Eligibility

DISEASE CHARACTERISTICS:
