title: Long-term results of the APO protocol (vincristine, doxorubicin [adriamycin], and prednisone) for treatment of mediastinal lymphoblastic lymphoma.
abstract: Twenty-one patients with biopsy-proven mediastinal lymphoblastic lymphoma were treated with the APO protocol (vincristine, doxorubicin, and prednisone). Treatment consisted of two years of therapy with a modified doxorubicin-containing acute lymphoblastic leukemia regimen with preventive cranial irradiation and intrathecal methotrexate. The median age in the group was 13 years (range, 2.5-22 years). Complete remission was obtained in 20 of 21 patients. Three patients required mediastinal irradiation for successful remission induction. Six patients have subsequently relapsed: two in the central nervous system, one in the central nervous system and testicle, one in the testicle, one in the pleura, and one in the abdomen. The median follow-up is six years (range, 16 months to 9.5 years) and a Kaplan-Meier estimate of disease-free survival at three years is 58% +/- 23% (2 SE).
