Von Hippel-Lindau disease: new strategies in early detection and treatment.
Von Hippel-Lindau disease is an autosomal dominant inherited disorder causing hemangioblastomas of the central nervous system (CNS), retinal hemangiomas, renal cell carcinomas, pheochromocytomas, pancreatic and liver cysts, and epididymal cystadenomas.


OBJECTIVE
Since 1976, we have periodically screened for the lesions in a large affected family and were able to evaluate new strategies in detection and treatment.


METHODS
A total of 23 individuals underwent the screening program. A multidisciplinary team of physicians was involved.


RESULTS
In 13 patients (7 females and 6 males), a total of 31 tumors was detected; hemangioblastoma of the CNS (9), retinal angioma (4), renal involvement (8), pheochromocytoma (4), pancreatic lesions (4), and liver lesions (2) were diagnosed by periodic family screening. On the basis of more than 10 years of experience and current literature, new criteria for diagnosis and treatment have been proposed.


CONCLUSIONS
The von Hippel-Lindau disease gene appears to be a tumor suppressor gene, and its absence or a defect in its structure is responsible for the predisposition to the disease. Tumor development depends on a somatic second mutation in the homologous allele. That means, in disease-gene carriers, tumor growth may begin at any age. Most of the lesions can be treated successfully when diagnosed in time. Periodic screening by a multidisciplinary team has to be continued lifelong.
