Hazard functions obtained from the Cox proportional hazards model. (a) Tumor type had a significant effect on overall hazard for tumor mortality (P = 0.006). Hazard ratios were smaller for gynecological cancers, lung cancer and other cancer types, compared to melanoma, pancreatic/hepatocellular/biliary tract cancers and colorectal/gastric cancers. (b-c) WHO performance status and gender were significant factors in Cox model (P < 0.001 and P = 0.017, respectively). (d) Patients who received virus coding for immunostimulatory transgene as first treatment had smaller hazard ratios compared to other patients (P = 0.001).
