We found an association between high PAI-1 and uPAR-del4/5 mRNA expression levels and an increased risk of tumor-related death for R0 patients using multivariate Cox regression analysis with relative risks (RR) of 6.55 (95%CI = 1.0-44.5) and 6.00 (95%CI = 0.8-47.1), respectively, with a trend towards significance (P = 0.054 and P = 0.088, respectively; Table 3). The gene discussed is SERPINE1; the disease is neoplasm.
