Results of renal transplantation in patients with renal cell carcinoma and von Hippel-Lindau disease.

BACKGROUND

Patients with von Hippel-Lindau (VHL) disease are at risk for the development of end-stage renal failure from the treatment of localized renal cell carcinoma. Transplantation with its attendant immunosuppression may predispose patients to tumor recurrence; however, there is little information regarding the outcome with this approach. In this article, we review the North American and European experience with renal transplantation in this patient population.

METHODS

The study group comprises 32 patients who have VHL rendered anephric secondary to localized renal cell carcinoma and who have undergone renal transplantation. Patients were identified from North American (n=18) and European (n=14) registries. The outcome of the study group is compared with a cohort of 32 renal transplant recipients without VHL from the Cleveland Clinic Unified Transplant Data Base, who were matched for donor source, gender, age, transplant status (primary vs. regraft), and date of transplantation.

RESULTS

The 23 men and 9 women in the study group received transplants between 1974 and 1996. The average age at transplantation was 36 years, and the average duration of dialysis before transplantation was 26 months. Patients have been followed for 48+/-35 months. There was no statistically significant difference in graft survival, patient survival, or renal function between the study and control groups. There were five deaths in both the study and control groups. In the study group, three patients died with metastatic disease. There was no difference in the duration of dialysis before transplantation between patients who developed metastatic disease and those who did not.

CONCLUSION

These data support the utility of renal transplantation as an effective form of renal replacement therapy in this unique population, with a limited risk of recurrent cancer.
