ABSTRACT
BACKGROUND:
As the incidence of urological malignancies after renal transplantation (RT) is observed to be greater than in the general population, a better understanding of them is important. We present our experience with urological tumors in RT recipients at our transplant center, and analyze their incidence, management and outcomes. MATERIALS ANDMETHODS:
A retrospective analysis of 2177 RT recipients on follow-up at our center between 1990 and 2022 was conducted for de novo genitourinary malignancy. Patients diagnosed with malignancy before transplantation were excluded. Clinicopathological data at diagnosis and follow-up were collected and analyzed. Kaplan-Meier estimates were used to evaluate overall survival (OS) and cancer-specific survival (CSS). Statistical analysis was performed using IBM SPSS v.24 (IBM Corp., Armonk, NY, USA).RESULTS:
The overall incidence of Urological malignancies was 3.9%, with 89 cancers diagnosed in 85 patients. Renal cell carcinoma was most common (n = 61, 68.5%), followed by prostate cancer (n = 10, 11.2%), urothelial carcinoma (n = 10, 11.2%), squamous cell carcinoma of the penis/scrotum (n = 7, 7.9%), and testicular cancer (n = 1, 1.1%). Mean duration between transplantation and diagnosis of malignancy was 9.9 (0.4-20.7) years. At a median follow-up of 4.6 (018.2) years, 27 deaths were seen; 7(25.9%) were due to urological malignancy. CSS rates were 86% and 78% at five and ten years, respectively, after diagnosis.CONCLUSION:
We present one of the largest series of de novo urological malignancies observed over an extended 30-year follow-up of RT recipients, demonstrating an elevated risk in line with other studies. Regular surveillance for malignancies is advised, in order to ensure early diagnosis and management.Palavras-chave
