Time to development of de novo malignancy after orthotopic liver transplantation (OLT) according to tumor type. *Others include three patients with ENT and four patients with urogenital tumors.

Kaplan–Meier survival curve for 50 patients with de novo malignancy (cases) and 50 patients without de novo malignancy (controls) after orthotopic liver transplantation (OLT). Time zero represents the date of liver transplantation. The difference in survival between cases and controls was statistically significant by log-rank test (p = 0.02).

Kaplan–Meier survival curve for patients with non-skin cancer vs. skin cancer and controls after orthotopic liver transplantation (OLT). Time zero represents the date of liver transplantation. The 33 patients with non-skin had significantly worse survival than the 17 patients with skin cancer (p = 0.0001 by log-rank test; hazard ratio 4.9, 95% CI 1.67–14.2, p = 0.004).

Kaplan–Meier survival curve after tumor diagnosis for patients with de novo malignancy after orthotopic liver transplantation (OLT) according to tumor type. Time zero represents the date of tumor diagnosis. A statistically significant difference was found in survival between different tumor types and skin cancer (p = 0.003 by log-rank test).
