Introduction
We aimed to report national standardised incidence for malignancy post transplant compared to the general population stratified by solid organ categories. In this study we report our findings for kidney transplantation on behalf of the Irish post transplant malignancy working group.
Methods
The national kidney transplant registry was linked with the national Irish Cancer Registry to capture episodes of malignancy over follow up. Standardised incidence ratios (SIRs) were calculated in comparison to the general population using the Irish census data as the denominator, and using ICD10 coding for malignancy diagnosis. Transplant recipients were considered at risk beginning at transplantation or start of cancer registry coverage on 01/01/1994. Follow-up ended at death or at the cancer registry censor date 31/12/2014. Only the first cancer diagnosis at each site is considered when calculating SIRs.
Results
See table 1 for SIRs for various malignancies post kidney transplant.
Conclusions
This study provides national data on cancer incidence following kidney transplantation in comparison to the general population in Ireland. These increased rates of cancer in transplant patients emphasise the need for careful long-term management.
