| 2 | Epidemiological study of a von Hippel-Lindau family in northwest China显示文摘von Hippel-Lindau(VHL)disease is a rare,inherited neoplastic disease characterized by hemangioblastomas(HBL)of the central nervous system(CNS),retinal angiomas,renal cell carcinomas(RCC),pancreatic endocrine tumors(PETs),pheochromocytomas,paragangliomas,and visceral cysts.We encountered a large VHL family in northwest China and conducted a systematic screening of the family members based on their epidemiological and clinical characteristics.A self-designed questionnaire was used to collect the general sociodemographic and health information of the family members.For the preliminary family screening,physical examination and abdomen B ultrasonography were performed.The suspected patients were subjected to cranial computerized tomography and fundus examination.The clinical data of the patients with confirmed VHL disease were collected from hospital records.A total of 63 lineal descendants in six generations were observed in the family(generations O,A,B,C,D,E),including 9 dead suspected cases(6 males,3 females)and 10 living cases(2 males,8 females).Among the 10 living cases,4,2,1,3,4,8,and 2 manifested HBLs of the CNS,PETs,RCC,pancreatic cysts,renal cysts,pheochromocytomas(4 hemi and 4 bilateral),and paragangliomas,respectively.Data showed that the morbidity of VHL disease in generation C was lower than that in generation B,but the age of onset was younger.This study is the first to report VHL disease in northwest China and VHL-associated PET cases in Chinese.Therefore,follow-up checkups of the family should be focused on younger generations.Proper family screening protocols should be followed for the treatment of patients with VHL disease. | Jingyao Zhang Dapeng Wu Hong Ai Jigang Bai Shunbin Dong Qinling Yang Kai Qu Lei Zhou Xinsen Xu Chang Liu | 2013 | Frontiers of Medicine2013，7，3： | 0 |
