Utilizing the stathmokinetic principle of timed vincristine and bleomycin, we combined these two agents with Mitomycin-C. The dose schedule included vincristine 0.5 mg/m2 intravenously (i.v.) geginning on day 1 and repeated twice weekly for 12 weeks; each injection was followed in 6-12 hours by bleomycin 6 mg/m2 for 12 weeks. Mitomycin-C was administered as a 20 mg/m2 bolus beginning on day 2 and repeated at 6-week intervals. Thirty patients were entered into this study, 27 were fully available for response. Thirteen patients (48%) met criteria of response (greater than 50% reduction in volume of measurable tumor). Significant myelosuppression resulted from this therapy. Median leukopenia nadir was 3.8 X 10(3) cells/mm3 and median thrombocytopenia nadir was 116 X 10(3) cells/mm3. Additional toxic reactions included anemia, lassitude, anorexia, peripheral neuropath fever, and skin rash. Despite significant, but manageable, toxicity, this combination appears to represent an improvement in the chemotherapy of a traditionaly refractory solid tumor.
