UNASSIGNED: @entity1071 ( @entity1071 ) incidence is difficult to determine, mainly because both early and other lesions may go unrecognized and unregistered. Few studies have included systematic pathology review to maximize case identification and decide more accurately @entity1071 frequency after long-term post-transplantation follow-up. A retrospective population-based cohort study including all kidney transplant recipients at two Danish centres (1990-2011; population covered 3.1 million; 2175 transplantations in 1906 @entity1 ). Pathology reports were reviewed for all @entity1 biopsies to identify possible PTLDs. Candidate PTLDs underwent histopathological review and classification. Seventy @entity1071 cases were identified in 2175 transplantations (3.2%). The incidence rate (IR) after first transplantation was 5.4 cases per 1000 @entity1 -years (95% CI: 4.0-7.3). Most PTLDs were monomorphic (58.5%), or early lesions (21.5%). Excluding early lesions and @entity1 <18 years, IR was 3.7 (95% CI: 2.9-5.5). Ten @entity1 with @entity1071 were retransplanted, 2 developing further PTLDs. Post-transplant @entity1 survival was inferior in @entity1 with @entity1071 , while death-censored graft survival was not. Using registry data together with extensive pathological review and long follow-up, a rather high incidence of @entity1071 was found.
