A phase II study of continuous infusion 5-fluorouracil in advanced hormone refractory prostate cancer. An Illinois Cancer Center Study.

BACKGROUND: 5-Fluorouracil (5-FU) has been previously associated with therapeutic benefit in hormone refractory prostate cancer. However, no previous study has administered 5-FU as a prolonged continuous infusion, which may be the optimal schedule for this cell-cycle specific agent. METHODS: Therefore, 25 patients were treated with 5-FU administered as a continuous intravenous infusion at a dose of 1000 mg/m2/day for 5 days every 28 days. Eligibility required disease defined by bidimensionally measurable lesions or evaluable lesions on bone scan or radiograph with elevated serum levels of prostate-specific antigen (PSA), no severe cytopenias, and an Eastern Cooperative Oncology Group performance status less than 3. Prior chemotherapy was not allowed. Dose modifications were specified for mucositis and hematologic toxicity. RESULTS: Eighteen of 22 patients were evaluable for response and toxicity, whereas 4 were evaluable for toxicity alone. Toxicity was significant using this dose and schedule and included episodes of sudden death (one patient), paroxysmal supraventricular tachycardia (one patient), and congestive heart failure (one patient). Other Grade 3 toxicities included stomatitis (two patients) and diarrhea (one patient). Significant myelosuppression did not occur. Objective responses were not observed, but 12 patients experienced stable disease with a median duration of 4 months. CONCLUSIONS: Infusional 5-FU can not be recommended for the treatment of advanced hormone refractory prostate cancer.

Phase II evaluation of iproplatin in patients with advanced gastric and pancreatic cancer.

A total of 48 patients with measurable advanced gastric adenocarcinoma (n = 16) or adenocarcinoma of the exocrine pancreas (n = 32) were prospectively treated with iproplatin at a starting dose of 270 mg/m2 intravenously over 2 hours. The dose was repeated every 28 days, and dose escalations or reductions were made on the basis of toxicity in the preceding course. No patient with gastric carcinoma achieved either a complete or partial response. One partial response and two complete responses were seen with pancreatic adenocarcinoma for an overall response rate of 10%. One patient has remained free of disease for more than 2 years. The major toxicities were granulocytopenia, thrombocytopenia, nausea, vomiting, and diarrhea. All toxicities were reversible upon discontinuation of the drug. On the basis of this trial, we conclude that iproplatin has no substantive activity in advanced gastric or pancreatic carcinomas.

A phase I trial of high-dose diaziquone and autologous bone marrow transplantation: an Illinois Cancer Council study.

Diaziquone (AZQ), a synthetic quinone with demonstrated activity against acute nonlymphocytic leukemia (ANLL), primary CNS tumors, and non-Hodgkin's lymphoma (NHL), is virtually devoid of nonhematopoietic toxicity at conventional doses. As a prelude to its inclusion into bone marrow transplant (BMT) preparative regimens, a phase I study of high-dose AZQ with autologous BMT (ABMT) was performed. Patients with refractory solid tumors and lymphomas were treated with a single 24-hour infusion of AZQ at 50 to 355 mg/m2 in dose escalations of 20%. Fifty-six patients received 69 courses. Those receiving greater than 60 mg/m2 had nadir granulocyte and platelet counts less than 500/microL and 20,000/microL, respectively. Nausea, vomiting, stomatitis, and diarrhea were mild, transient, and not dose-related. Transient minimal elevations of liver function tests were seen in five patients and were also not dose-related. The maximally tolerated dose (MTD) of high-dose AZQ was found to be 245 mg/m2, with nephrotoxicity being dose-limiting. Significant azotemia was seen in four of 12 patients treated at 295 and 355 mg/m2, including fatal anuric renal failure in three of these patients. Reversible proteinuria also occurred in 24 of 26 courses above 150 mg/m2, including nephrotic range proteinuria in eight courses, all at doses of 205 to 355 mg/m2. The proteinuria was also associated with multiple proximal tubular defects including generalized aminoaciduria and proximal renal tubular acidosis. There were six early deaths including two of early renal failure (295 and 355 mg/m2), two of sepsis (205 and 245 mg/m2), one of a pulmonary embolus (85 mg/m2), and one of progressive disease (60 mg/m2). Of 50 patients who were assessable for response, there were seven responses including two of 10 with primary CNS tumors, one of 12 with malignant melanoma, one of five with non-small-cell lung carcinoma, two of two with breast carcinoma, and one of one with ovarian carcinoma. Because of its activity in ANLL and NHL and its unique toxicity spectrum, high-dose AZQ may improve the efficacy of current BMT preparative regimens without significantly increasing their nonhematopoietic toxicity.
