Treatment with low-dose warfarin improved survival irrespective of the chemotherapy received. Of the regimens examined, the combination of regional gemcitabine and mitomycin-C with systemic gemcitabine was associated with the longest survival time. Survival was increased further by the addition of warfarin. These data provide a rationale, based on safety and efficacy, for a definitive study on the use of warfarin and combined regional and systemic chemotherapy in patients with pancreatic carcinoma.
