Comparison of patient survival between various subgroups among renal transplant patients: a single center experience.
OBJECTIVE
To compare patient graft survival between various subgroups among renal transplant patients.


METHODS
A retrospective analysis of all renal transplant patients from January 1, 1993, to June 1, 2003, was performed using follow-up records and data submitted to the National Renal Registry.


RESULTS
A total of 91 renal transplant patients were followed, with a male-to-female ratio of 57:34 (62.6%:37.4%) and mean age at transplant 35.6 +/- 12.1 years (range 10.1-64.4 years) with 38 (41.8%) cases transplanted locally and 53 (58.2%) cases transplanted overseas, of which 36 (39.6%) were from live donors and the remaining 55 (60.4%) from cadavers. As of June 1, 2003, 50 transplant patients are on regular follow-up, with 41 patients lost due to 12 (29.3%) deaths, 16 (39.0%) graft failures, 11 (26.8%) transfers, and 2 (4.9%) lost to follow-up. Overall patient and graft survival rates at 2, 5, and 10 years were 93.1%, 77.4%, and 49.2%, respectively. Survival rates for male transplant patients were 91.4%, 71.9%, and 46.7% compared to 96.1%, 86.9%, and 53.6% for females. Survival rates for Malay race patients were 92.0%, 59.5%, and 28.6%; Chinese rates were 96.0%, 81.6%, and 54.8%, and Indian rates were 81.0%, 81.0%, and 46.3%, respectively. The survivals for transplants from living donors were 96.9%, 85.6%, and 62.3% compared to cadaveric kidney transplants namely 89.9%, 71.3%, and 35.0%. The local transplant survival rates were 96.9%, 82.3%, and 60.8% compared to overseas transplants, with survival rates of 89.9%, 73.5%, and 35.7%. Finally, living-related donor transplantation survival rates were 96.8%, 84.9%, and 62.2% compared to nonrelated donors-90.1%, 71.3%, and 35.0%-at 2 years, 5 years, and 10 years, respectively.


CONCLUSIONS
Overall survival has been good. The survival rates were better among female gender, Chinese race, local transplantation, and kidneys from living-related donors.
