[Renal transplantation and malignancies: A single-centre experience (25 years)].
BACKGROUND
The prevalence of post-transplant malignancies, in renal transplant recipients, is higher than that expected in age and sex-matched controls from the general population, and there is a markedly increased incidence of certain cancers.


METHODS
In 1137 renal transplant recipients (1020 from cadaveric and 117 from living donors, M/F 771/366) performed at the S. Orsola Renal Transplantation Centre since 10/1976 to 9/2001, we studied the post-transplant cancer prevalence, the correlation between cancer prevalence and population characteristics, the risk factors (smoke, cancer history, positive HBsAg and antiHCV infection) and the immunosuppressive therapy.


CONCLUSIONS
The prevalence of malignancies was 3.86% (52 malignancies in 44 patients). The period between transplant and diagnosis of malignant disease was 59 +/- 85 months. Skin cancer was the most common (n=16; 30.7%), followed by lymphoproliferative disorders (n=8; 15.4%), Kaposi s sarcoma (n=6; 11.5%), uterine cancer (n=6; 11.5%), renal carcinoma of native kidney (n=5; 9.6%), cancer of breast/stomach/pancreas and urinary bladder (n=2; 3.8%) and other cancers (n=5; 9.6%). The mean duration of dialysis before transplantation was longer in cancer patients (41+/- 32.1 vs. 33.5 +/- 32.4 months). We found a correlation between types of malignancies and viral infection in NH-lymphoma (EBV positive 4/4) and skin cancer (HZV positive 13/16). We also detected a correlation between Aza and skin cancer (16/22) and CyA and lymphoproliferative disorders (7/8).
