This report describes the results of a study of central nervous system (CNS) prophylaxis and combination chemotherapy for the maintenance of remission in adult acute lymphoblastic leukemia. Adults with acute lymphoblastic leukemia who achieved complete remission were treated with 2,400 rads cranial irradiation and intrathecal methotrexate for CNS prophylaxis followed by continuation systemic chemotherapy with oral methotrexate, 6‐mercaptopurine and cyclophosphamide. There were no CNS relapses following treatment. One‐half of the patients relapsed within 11 months, with 5 patients remaining in remission for 27+ to 31+ months. The toxicity was acceptable with no treatment‐related deaths. This regimen is capable of producing long remissions in a significant proportion of adults with acute lymphoblastic leukemia and appears to be effective in reducing the incidence of CNS relapse. It has the additional advantage of ease of administration and can be largely administered in the community.
