Combination chemotherapy with bleomycin (NSC-125066), vincristine (NSC-67574), and methotrexate (NSC-740) plus split-course radiotherapy in the treatment of non-oat-cell bronchogenic carcinoma.

Twenty-seven unselected patients with limited disease non-oat-cell bronchogenic carcinoma were treated with a chemotherapy- radiotherapy protocol which consisted of bleomycin, vincristine, and methotrexate followed by split-course radiation. There were 15 objective responders with a median survival time in excess of 70+ weeks in contrast to a median survival time of 26 weeks for nonresponders (P less than 0.01). Objective benefit was limited to the epidermoid carcinoma group since none of the adenocarcinoma group achieved a greater than 50% reduction in maximum tumor diameter. The median survival time for the entire groups was 42 weeks in contrast to a recent split-course radiotherapy historical control group whose median survival time was 38 weeks. Toxic effects were predominantly gastrointestinal.

Clinical trial of bleomycin (NSC-125066) in the treatment of metastatic renal carcinoma.

This study had the limited aim of ascertaining the efficacy of bleomycin in controlling m etastatic renal carcinoma. Fifteen patients received bleomycin intramuscularly and five patients received the drug via continuous infusion. Only two patients had responses, both mixed. We concluded that the therapeutic value of bleomycin in the treatment of advanced renal carcinoma is negligible.

Continuous intravenous bleomycin (NSC-125066) therapy with vinblastine (NSC-49842) in stage III testicular neoplasia.

Twenty-three patients with stage III germinal neoplasia of the testis were treated with a variation of our original vinblastine-bleomycin program. This modification consisted of 0.4 mg/kg of vinblastine given in two fractions on Days 1 and 2 followed by continuous intravenous administration of 30 units of bleomycin in 1000 cc of 5% glucose and distilled water over a 24-hour period for 5 successive days beginning on Day 2. Therapy was repeated every 28-35 days as toxicity permitted. There were 17 responses, nine of which were complete (39%). Eight of the complete responses were in patients with massive disease in whom a low complete response rate was expected. Toxic effects consisted of severe leukopenia in 90% thrombopenia in 50%, and unexplained transient hyperbilirubinemia in about 30% of the patients. Bleomycin pneumonitis occurred in one patient and resulted in death. Hypertension was a new and unexpected side reaction experienced by four patients. Further trials are indicated since the complete response rate in patients with advanced massive disease appears to be improved.
