Abstract
Sixty-three patients with Stage III and IV lymphocytic lymphoma were randomized for induction treatment between a single course of nitrogen mustard and a 14-day course of prednisone (conservative therapy) or sequential rotation of BCNU, nitrogen mustard and cytoxan with intermittent vincristine and prednisone for 6 months (extended therapy). Maintenance therapy by an oral alkylating agent (cytoxan or chlorambucil) with or without prednisone was given. Complete remission occurred in 75% of the conservative and 77% of the extended therapy group. The median duration of remission was similar, and greater than 27 months in both groups, and there was no difference in survival. At 1 year 80% of patients with no prior chemotherapy were in remission vs. 47% of patients with prior chemotherapy (p < .01). No significant advantage for extended chemotherapy was found. The addition of vincristine was not helpful in induction and prednisone during maintenance did not improve the duration of remission or survival.
