Vinblastine infusion in non-Hodgkin's lymphomas: lack of total cross-resistance with vincristine.

Historically, vinblastine given by intravenous bolus injection has not been an effective treatment for non-Hodgkin's lymphomas; vincristine has displayed greater activity. Also, vinblastine has generally been considered to be cross-resistant with vincristine in such patients. In an attempt to overcome these obstacles, a protracted infusion of vinblastine was administered (0.
