ABSTRACT
Objective To explore the outcomes of kidney transplant recipients who developed urinary and male genital cancers after transplantation. Methods Data of 31 kidney transplant recipients developed de novo urinary and male genital cancer were compared with data of 31 patients in general population with the same age and same tumor stage. Results Compared with the general population, the overall survival was significantly worse in the transplant recipients (P=0. 02) , 5-year survival rates for each group were 50% vs 68%. Multivariate analyses demonstrated cancer stage to be a negative risk factor for survival for transplant recipients with de novo urinary and male genital cancer, and surgery and functioning graft to be the positive survival predictors. Conclusions Transplant recipients experience worse outcomes than the general population from urinary and male genital cancers. Cancers in transplant recipients are more biologically aggressive at the time of diagnosis.
