Abstrakt:	Background: Patients with primary sclerosing cholangitis (PSC) may be at higher risk of malignancy after liver transplantation (LT) compared to other LT recipients. We aimed to determine the cumulative incidence of/risk factors for long-term cancer-related mortality in patients with PSC after LT. Methods: All adult patients underwent LT for PSC without cholangiocarcinoma from 1984 to 2012, with follow-up through June 2015. We estimated cumulative incidence, risk factors, and mortality from de novo malignancies after LT. Results: Two hundred ninety-three patients were identified (mean [SD] age, 47 [12] years; 63.3% males; 2.4% smoking at LT). Over a median of 11.5 years (range, 6.4-18.6 years), 64 patients (21.8%) developed 73 nonskin cancers, including 46 solid-organ cancers (renal, 11; colorectal, 11; prostate, 7; breast, 5; pancreas, 5; ovarian/endometrial/vulvar cancers, 3; and de novo cholangiocarcinoma, 4). Twenty-two patients developed hematologic malignancies (posttransplant lymphoproliferative diseases, 18; Hodgkin disease, 2; and myelodysplastic syndrome, 2). Five patients developed melanoma. The 1-, 5-, 10-, and 20-year cumulative incidences of cancer were 2.1%, 8.6%, 18.7%, and 27%, respectively. Mortality of patients with PSC who developed cancer was higher than that of patients with PSC without cancer (hazard ratio, 2.2; P < 0.01). On multivariate analysis, recipient's age and elevated pre-LT international normalized ratio were associated with increased risk of de novo (nonskin) malignancy. Conclusion: The 10-year cumulative risk of cancer after LT for advanced-stage PSC was 18.7%, with posttransplant lymphoproliferative diseases, colorectal cancer, and renal cell cancer being the most common. Post-LT de novo nonskin cancer decreased overall posttransplant survival. Only recipient's age and elevated international normalized ratio at LT were associated with increased nonskin cancer risk.
