Adriamycin (NSC-123127) therapy for advanced gastrointestinal cancer.

Sixty-nine patients with advanced gastrointestinal carcinomas were given adriamycin intravenously at a dose level of 40-75 mg/m once every 3 weeks. Toxic effects included nausea, vomiting, diarrhea, stomatitis, alopecia, leukopenia, thrombocytopenia, and minor ECG changes. There was a slight trend toward move severe leukopenia in patients with markedly abnormal liver function test (serum glutamic oxaloacteic transaminase and alkaline phosphatase). Of the 57 pateints with colorectal cancer treated with adriamycin, four (7%) showed partial objective responses. In a controlled comparison of adriamycin versus 5-fluorouracil (5-FU) in patients with previously untreated large bowel carcinoma, three of 23 patients (13%) receiving adriamycin showed partial objective responses as compared with six of 25 patients (24%) receiving 5-FU. The median duration of response with adriamycin was 3 months com pared to over 6 months with 5-FU. Four of eight patients with gastric carcinoma showed partial objective responses. No responses were noted in a small number of patients with pancreatic and gallbladder carcinomas. Adriamycin would not seem to have any role in the treatment of advanced colorectal carcinoma. Our results, however, would justify further evaluation of this agent in gastric carcinoma.

Phase II study of recombinant alfa-2a interferon in patients with advanced bone sarcomas.

Twenty previously treated patients with advanced bone sarcomas received thrice weekly im 50 X 10(6) IU/m2 doses of human alfa-interferon (interferon alfa-2a, recombinant; Roche). Seventeen patients had metastatic osteosarcomas and one each had fibrosarcoma, mesenchymal chondrosarcoma, and malignant fibrous histiocytoma. Two patients with osteosarcoma and the one with malignant fibrous histiocytoma experienced objective partial tumor regression for 1, 3, and 2 months, respectively. Fever, anorexia, myalgia, fatigue, lethargy, and moderate myelosuppression were observed commonly, and some patients developed mild nausea, vomiting, and diarrhea. No patient withdrew because of toxicity and no dose reductions were necessary except adjustments for changes in body surface area secondary to weight loss.

Phase II evaluation of dianhydrogalactitol in advanced head and neck carcinomas.

Twenty-eight patients with advanced squamous cell carcinomas and adenocarcinomas of the head and neck were treated with dianhydrogalactitol at a dose of 25 mg/m2 iv on each of 5 consecutive days monthly. All patients except one had received previous surgical and/or radiotherapeutic treatments and 12 had received previous chemotherapy. Disease progression (or symptomatic deterioration) occurred in nine patients after the initial course and in eight others after two courses. In 11 patients, the disease remained stable during at least three courses; however, no instances of objective regression of disease were observed during treatment with dianhydrogalactitol despite significant toxic effects in most patients.

Cyclophosphamide and VP-16-213 with or without cisplatin in squamous cell and small cell lung cancers.

Forty-seven patients with squamous cell or small cell lung cancer (28 [60%] of whom had cardiac disease too severe to permit the use of doxorubicin) were treated with cyclophosphamide and VP-16-213 with or without cisplatin. Four of 11 patients with squamous cell (36%) and 19 of 24 patients with small cell (79%) cancers had tumor regressions (eight complete regressions) on the three-drug regimen. Median survival times for the 31 patients with small cell lung cancer were 9 months for those with extensive disease and 12.2 months for those with limited disease. The data suggest that the roles of VP-16-213 and cisplatin need further evaluation in these cell types and that doxorubicin may not be mandatory for successful treatment of squamous cell and small cell lung cancers.

Phase I study of diaziquone.

Twenty-eight patients received diaziquone (AZQ) as a single iv dose ranging from 2 to 27.5 mg/m2 in a phase I study. Myelosuppression was dose-limiting, tended to be cumulative, and was somewhat unpredictable in its occurrence. No pretreatment patient characteristics or chemical abnormalities were found to be consistently related to hematologic toxicity. No objective responses were noted in this study, with most patients having gastrointestinal neoplasms. A single iv injection of 22.5-27.5 mg/m2 of AZQ given every 4-5 weeks would be a suitable initial schedule. Pharmacokinetic studies revealed that the plasma elimination of AZQ was best described by a two-compartment open model with rapid plasma elimination of the parent drug.

Phase II evaluation of the combination of triazinate, cyclophosphamide, doxorubicin, and cis-diamminedichloroplatinum(II) in patients with advanced adenocarcinoma of the lung.

In an attempt to improve upon the 43%-48% regression rates noted for various CAP regimens consisting of cyclophosphamide, doxorubicin (Adriamycin), and cis-diamminedichloroplatinum(II) in various doses and schedules, triazinate was added to that three-drug combination, and the new combination (T-CAP) was evaluated in patients with advanced adenocarcinoma of the lung. T-CAP produced a regression rate of 57% with a 7-week increase in overall median time to progression and a 4-week increase in overall median survival compared to the best of the CAP schedules. More stomatitis and dermatitis were noted with the new combination, but myelosuppression was similar to that of the CAP regimens. These data suggest that further studies with triazinate should be conducted in patients with adenocarcinoma of the lung.
