Carcinoma of the pancreas is a virulent malignancy. We performed a Phase II survival study by treating 30 patients with pancreatic cancer with leucovorin, 200 mg/m2 × 5 days immediately followed by 5-fluorouracil, 370 mg/m2 every 4 weeks. We examined the survival of our 30 study patients with patients drawn from the Manitoba Tumor Registry, matched for important prognostic criteria. Classical response rates were also evaluated in those patients who had measurable tumors. The response rate was 13% with two complete remissions and one partial remission, with 40 patients (7.8%) demonstrating stable disease for 2 months, and 39% of patients demonstrating progressive disease while on treatment. The mean survival of the Phase II-treated group was 16 weeks, compared to 12 weeks in the matched controls, which indicated an increase in survival of 30%. This was significant at the p = .001 level. Toxicity was not as great as expected. This trial demonstrates that there may be marginal survival benefit with 5FU leucovorin in pancreatic cancer, but more profound prolongation needs to be seen with chemotherapy regimens before instituting randomized trials.
