Abstract
Background
von Hippel–Lindau (VHL) disease is an autosomal dominant disorder caused by variants of the VHL tumor suppressor gene (VHL). Early detection and treatment are essential to prevent morbidity and mortality. We evaluated the effectiveness of surveillance strategies and the utility of a VHL clinic with a multidisciplinary team for the first time in Korea.
Methods
The VHL clinic was organized at the Samsung Medical Center in 2011 and consisted of a multidisciplinary team, including an endocrinologist, urologist, general surgeon, neurosurgeon, ophthalmologist, otolaryngologist, and radiologist. Biochemical and imaging surveillance and personalized genetic counseling were conducted at the VHL clinic and patients were referred to the necessary departments upon detection of disease manifestation. We divided the patients in three groups (I–III) based on their compliance to VHL clinic attendance.
Results
Between 2011 and 2018, 50 VHL patients were identified by VHL molecular analysis and referred to the VHL clinic. Most patients regularly participated in imaging of the central nervous system (43/50, 86.0%) and of the abdomen (46/50, 92.0%). However, there were differences in compliance to determination of the catecholamine level, audiometry, and ophthalmic examination among the three groups.
Conclusions
We present the results of using a multidisciplinary team approach and showed that the VHL clinic strategy is useful for the comprehensive surveillance and management of VHL disease. We hope that VHL clinics will be widely set up in hospitals to improve prognosis in patients with VHL.
