This study was done to analyze the clinical characteristics of renal cell carcinoma (RCC) in Korean patients with von Hippel-Lindau (VHL) disease. Between January 1996 and July 2008, 1,514 patients were diagnosed with RCC and 24 patients were diagnosed with VHL disease at our institute. We analyzed the clinical characteristics of the 24 patients diagnosed with VHL. The mean age of patients with VHL was 39.2+/-12.6 yr; the mean age of patients with both VHL and RCC was 42.5+/-10.3 yr. Among the 24 patients with VHL, 7 patients had retinal angiomas, 11 had RCC, 16 had renal lesions, 18 had pancreatic lesions and 21 had cerebellar hemangioblastomas. There was no significant difference between survival rates of patients with VHL alone and those with VHL and RCC. However, cancer-specific survival rates were significantly different between patients with both VHL and RCC and patients with sporadic bilateral or multifocal RCC. In our Korean study, the incidence of RCC in patients with VHL disease is 45.8% and the incidence of VHL disease in patients with RCC is 0.73%. Due to the low overall incidence of VHL in Korea, extended multi-institutional studies are needed to establish the true characteristics of VHL disease.

    • "VHL syndrome is rare in Korea. However, some mutations in the VHL gene have been identified in association with RCC [21], spinal cord hemangioblastoma [22], and pheochromocytoma [23]. Although there have been no large-scale multicenter studies examining the genotype-phenotype correlation, a case series reported that the pancreatic involvement is as high as 89% (16/18) in Korean patients with VHL syndrome [24].

    ABSTRACT: Von Hippel-Lindau (VHL) disease is an autosomal dominantly inherited, multisystemic tumor syndrome caused by mutations in the VHL gene. To date, more than 1,000 germline and somatic mutations of the VHL gene have been reported. We present a novel mutation in the VHL tumor suppressor gene that presented with gestational diabetes mellitus. A 30-year-old woman presented with gestational diabetes mellitus. She sequentially showed multiple pancreatic cysts, spinal cord hemangioblastoma, cerebellar hemangioblastoma, and clear cell type renal cell carcinomas. Also, her father and brother had brain hemangioblastomas. Each of the three exons of the VHL gene was individually amplified by polymerase chain reaction and direct sequencing was performed using an ABI 3730 DNA analyzer. DNA sequence analysis to determine the presence of VHL mutation in her family revealed del291C, a novel frameshift mutation. We found a novel mutation in the VHL tumor suppressor gene that presented with gestational diabetes mellitus.

    ABSTRACT: Von Hippel-Lindau (VHL) syndrome is an inherited cancer syndrome in which patients are at risk of developing multiple tumors in different organs. 6-L-¹⁸F-fluorodihydroxyphenylalanine (¹⁸F-FDOPA) positron emission tomography (PET) is a relatively new metabolic imaging tracer proposed for the use of localizing sites of neuroendocrine tumors. There are limited data on the clinical utility of using ¹⁸F-FDOPA PET for identifying neuroendocrine tumors in a high-risk population such as VHL. The aim of this prospective study was to evaluate the clinical utility of ¹⁸F-FDOPA PET in patients with VHL-related tumors. Radiological findings were prospectively collected from four imaging modalities: computed tomography, magnetic resonance imaging (MRI), ¹⁸F-fluorodeoxyglucose PET, and ¹⁸F-FDOPA PET. ¹⁸F-FDOPA PET findings were compared with those from other imaging modalities, as well as with clinical and laboratory data, and pathology findings if patients underwent an operation. In 52 patients with VHL, 390 lesions were identified by computed tomography (n = 139), MRI (n = 117), ¹⁸F-fluorodeoxyglucose PET (n = 94), and ¹⁸F-FDOPA PET (n = 40). ¹⁸F-FDOPA PET identified 20 pancreatic and 20 extrapancreatic tumors, including lesions in the adrenal gland (n = 11), kidney (n = 3), liver (n = 4), lung (n = 1), and cervical paraganglioma (n = 1). These tumor sites were not seen by conventional imaging studies in 9.6% of patients and 4.4% of lesions. Seven of eight patients who had an ¹⁸F-FDOPA PET-positive lesion underwent resection, and pathology showed a neuroendocrine tumor. Four of 10 patients with positive adrenal uptake had elevated catecholamine levels, and six of 10 patients had a discrete mass on axial imaging. ¹⁸F-FDOPA PET is a useful complementary imaging study to detect neuroendocrine tumors in patients with VHL undergoing surveillance, especially in those suspected to have adrenal pheochromocytoma or unusual ectopic locations.

    ABSTRACT: To evaluate the effect of renal cell carcinoma (RCC) on survival in von Hippel-Lindau (VHL) disease and to assess the relationship between tumor size and survival. In this retrospective cohort study, the medical records of 72 patients who presented with VHL disease between 1994 and 2012 were reviewed. Clinical VHL-related characteristics were analyzed, and the prognostic value of renal tumor size for overall survival was assessed by using Cox regression models. Of the 72 VHL patients, 42 (58.3 %) and 30 (41.7 %) were male and female, respectively. The mean age was 37.9 years, and the median follow-up period was 61.5 months. In terms of VHL-related manifestations, 40 (55.6 %) had RCC, 46 (63.8 %) had hemangioblastoma in the cerebellum, 10 (13.9 %) had hemangioblastoma in the spinal cord, 34 (47.2 %) had a pancreatic mass, 18 (25.0 %) had pheochromocytoma, and 14 (19.4 %) had retinal capillary hemangioma. RCC was a major cause of mortality: Of the 11 patients who died, nine (12.5 %) died due to RCC progression. The 5-year overall survival rate was 85.6 % for all patients, 96.9 % for patients without RCC, 83.6 % for patients with RCC < 3 cm, and 75.8 % for patients with RCC ≥ 3 cm. Multivariable analysis showed that RCC ≥ 3 cm was an independent predictor of overall survival (HR 9.87, 95 % CI 1.17-83.00, p = 0.035) along with age (HR 1.05, 95 % CI 1.01-1.10, p = 0.027). Renal tumor size was an independent prognostic factor for overall survival in VHL disease. This observation will be helpful for planning RCC treatment in VHL disease.
