Ditazole (4,5-diphenyl-2-bis-(2-hydroxyethyl)-aminoxazol) inhibits in vivo platelet aggregation induced in mice by intravenous injection of cells derived from an experimental tumor, the Lewis lung carcinoma. Such a protective effect of ditazole could not be observed when the number of circulating platelets dropped slowly following intramuscular implantation and spontaneous dissemination of the same cancer cells. These results support previous observations suggesting a different mechanism for the thrombocytopenia observed after intravenous and intramuscular injection of cancer cells. Tail transection bleeding time of normal mice is significantly prolonged by ditazole, a finding at variance with that reported in rats.

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.

CCNU and Bleomycin, alone or in combination, were used to treat 397 evaluable cases of advanced cancer. Responses defined as 50% or greater reduction in all tumor masses occurred in 13/35 lymphomas, 8/50 brain cancers, and 28/312 other solid tumors. Hematologic toxicity of a life-threatening degree occurred in 33/298 patients evaluable for CCNU toxicity; in an additional 50 it was considered severe. Pulmonary toxicity was severe in 4 patients. Drug-associated deaths (4) included one each due to leukopenia and thrombocytopenia after CCNU; one due to pulmonary toxicity after Bleomycin; and one due to shock after the 20th dose of Bleomycin. There was no suggestion of synergism or additive activity with the two drugs.

In the previously published series of patients with generalized head and neck epidermoid carcinoma, a high dose combination of methotrexate (MTX) (0.4 mg/kg biw. i.v.) and bleomycin (BLM) (30 mg biw. iv) produced an objective remission rate of 60% with a median duration of 9 weeks. The disappointingly short duration of the remissions was tentatively related to the short period of treatment, which was limited to 5 weeks in order to keep the cumulative dosage of BLM below 300 mg. In the present study, covering 26 patients, a lower weekly dose was adopted (BLM 15 mg, MTX 0.6 mg/kg). 13 partial remissions were obtained with a median duration of 26 weeks; in 7 cases there was no evolution, in 6 cases progression of the tumor was registered, and there was one death from hematological toxicity. The major toxicity was leuko- and thrombopenia with one toxic death. Digestive and cutaneous side effects and fever were minor. There were 2 cases of major pulmonary toxicity, one of which was lethal. In conclusion, a combination of MTX and BLM at a relatively low dosage is active in disseminated head and neck carcinoma and appears to be compatible with longer maintenance of palliation in comparison with results obtained at a high dose level.

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.

Forty consecutive eligible patients with advanced bronchogenic carcinoma and no prior chemotherapy were treated with a 5-drug combination of methyl-CCNU, cyclophosphamide, methotrexate, vincristine, and bleomycin. Of the 36 patients who completed at least one 6-week course of treatment and were considered evaluable, 4 (11%) had partial tumor response. Response by cell type was as follows: 2(14%) of 14 patients with squamous cell carcinoma, 2(18%) of 11 with oat cell carcinoma, and none of 11 with adenocarcinoma. Toxicity in the group of 36 evaluable patients consisted of nausea and vomiting in 24 patients (67%), severe leukopenia (white blood cell count less than 1000 cells/-mm3) in 7 patients (19%), severe thrombocytopenia (platelet count less than 100,000 platelets/mm3) in 14 patients (39%), and bleomycin pulmonary toxicity in 2 patients (6%). This combination does not appear to be more effective than single-agent chemotherapy for bronchogenic carcinoma.

The Southwest Oncology Group has treated 130 patients with advanced disseminated uterine cervical carcinoma no longer amenable to therapy with further radiation or surgery. Patients received one of three different schedules of mitomycin C, vincristine and bleomycin. A twice weekly schedule of bleomycin and vincristine produced response in 60% of patients. An infusion bleomycin schedule produced response in 39% of patients and a once weekly vincristine bleomycin schedule produced a 25% response rate (45% overall). Responding patients lived significantly longer than nonresponders (30 vs 18 weeks). Toxicities encountered included leukopenia, thrombocytopenia, peripheral neuropathy, gastrointestinal upset, dermatitis, and alopecia. We believe two of the schedules utilized represent an improvement in producing tumor remission induction in this previously recognized refractory carcinoma.

A combination regimen consisting of cisplatin, bleomycin, and vinblastine was evaluated in 86 patients with metastatic testicular tumors. Prior therapy included surgical resection of primary tumor (84 patients), radiotheapy (21 patients), chemotherapy (33 patients). Thirteen patients received prior bleomycin and vincristine or vinblastine. Of 80 evaluable patients 51 achieved complete response (CR) and 26 achieved partial response (PR), for an overall response rate 96.5%. There was no significant difference in response rates or survival with respect to prior therapy, sites of metastatic lesions, and tumor histology. The median survival time was not reached in an observation period of 44+ months. Sixty patients were alive 11+--44+ months, and 57 of these were free of disease. Thirty-two of the 60 patients (53%) had a survival time greater than 20 months. Toxicities included nephrotoxicity (18 patients) leukopenia, (69 patients), thrombocytopenia (nine patients), and anemia (56 patients). Bleomycin-induced pulmonary toxicity was fatal in one patient. Other toxicities included nausea and vomiting, stomatitis, fever, alopecia, and neurological effects.

One hundred eighteen patients with metastatic carcinoid tumor were randomized to treatment with streptozotocin combined with cyclophosphamide or with 5-fluorouracil (5-FU). Commonly experienced side effects were nausea, vomiting, leukopenia, thrombocytopenia, and nephrotoxicity. Objective response rates among eligible and evaluable patients treated with the 5-FU combination was 14 of 42 (33%) and with the cyclophosphamide combination, 12 of 47 (26%). Among those patients with carcinoids primary to the small bowel the respective response rates were 44% and 37%. The overall response rates for patients with carcinoids of pulmonary or unknown origin were only 12% and 17%. There was no significant difference in patient survival between the two treatment arms. Among 11 patients who received crossover therapy with 5-FU alone there were two responders. There were no responders among eight patients treated with cyclophosphamide alone. Urinary 5HIAA excretion proved to be a useful biologic marker in these patients that correlated well with the observed measurements of tumor bulk. Median survival times from the diagnosis of unresectable malignant disease related to sites of origin of carcinoid tumor were the following: small bowel, 28.4 months; pancreas, 24.0 months; lung, 15.1 months; and unknown origin, 9.0 months. Metastatic carcinoid tumor is a malignant disease susceptible to chemotherapeutic approaches and continued investigation of the therapy of these neoplasms should be strongly encouraged.

A woman with multiple myeloma relapsed after 6 years of satisfactory tumor control with melphalan therapy. When progression then occurred, she was given exogenous human leukocyte interferon, 3 x 10(6) reference units twice daily i.m., as the sole therapy. Side-effects of the interferon therapy consisted of fever reactions and thrombocytopenia. One month after the initiation of interferon therapy there was 1) improvement of general health with less pain and tiredness, 2) reduction of the M-component, IgG-lambda, in the serum, and 3) a reduced plasma cell concentration in the bone marrow. After 5 months of interferon therapy tumor progression occurred despite continuous interferon treatment. At the same time, the tumor cells were less sensitive to interferon in in vitro tests than prior to interferon therapy. It is suggested that interferon therapy should be given as initial treatment to a few patients with multiple myeloma in a phase I trial.
