Popis: BACKGROUND Long-term immunosuppression imposes increased malignancy risk in renal allograft recipients, significantly contributing to overall morbidity and mortality. This study examined malignancy rates in renal allograft recipients at 2 years after conversion to a sirolimus (SRL)-based, calcineurin inhibitor (CNI)-free regimen. METHODS This open-label, randomized, multicenter study (the CONVERT Trial) randomly assigned 830 patients to SRL conversion (n=555) or CNI continuation (n=275). Patients with history of posttransplant lymphoproliferative disease or known/suspected malignancy within 5 years before screening were excluded. As part of standard safety measurements, subjects were monitored for any malignancy occurrence; both skin and nonskin malignancies were reported, even if the patient discontinued from the therapy. Malignancy rates were analyzed based on exposure time to study drugs (i.e., number of events per 100 person-years of follow-up). RESULTS At 2 years postconversion, the total number of malignancies per 100 person-years of exposure was significantly lower among SRL conversion patients compared with CNI continuation (2.1 vs. 6.0, P
