Lymphosarcoma. A comparison of extended to conservative chemotherapy.

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 less than .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.
