Abstract
A pilot study of the toxicity and efficacy of a new treatment schedule for childhood non‐Hodgkin's lymphoma was conducted by members of the Children's Cancer Study Group (CCSG) prior to its use in a randomized phase III trial. Chemotherapeutic agents used were cyclophosphamide (CPM), vincristine (VCR), and prednisone, together with intravenous (IV) and intrathecal methotrexate (IT MTX). Radiation therapy was also employed.From September 1976 to April 1977, 27 eligible, newly diagnosed patients with non‐Hodgkin's lymphoma were entered onto this pilot study. Toxicity was acceptable with minor adjustments in dosage and timing of the myelosuppressive agents. Fourteen of the 22 patients entered onto maintenance remain entirely disease‐free, and all have completed the prescribed course of chemotherapy. None of the 12 patients characterized as having a “favorable” prognosis has relapsed, with a median follow‐up of 27 months from on study.
