Natural history of malignant bone disease in renal cancer: final results of an Italian bone metastasis survey.

Abstract: Background: Bone metastasis represents an increasing clinical problem in advanced renal cell carcinoma (RCC) as diseaserelated survival improves. There are few data on the natural history of bone disease in RCC. Patients and methods: Data on clinicopathology, survival, skeletal-related events (SREs), and bone-directed therapies for 398 deceased RCC patients (286 male, 112 female) with evidence of bone metastasis were statistically analyzed. Results: Median time to bone metastasis was 25 months for patients without bone metastasis at diagnosis. Median time to diagnosis of bone metastasis by MSKCC risk was 24 months for good, 5 months for intermediate, and 0 months for poor risk. Median number of SREs/patient was one, and 71% of patients experienced at least one SRE. Median times to first, second, and third SRE were 2, 5, and 12 months, respectively. Median survival was 12 months after bone metastasis diagnosis and 10 months after first SRE. Among 181 patients who received zoledronic acid (ZOL), median time to first SRE was significantly prolonged versus control (n=186) (3 months vs 1 month for control; P,0.05). Conclusions: RCC patients with bone metastasis are at continuous risk of SREs, and in this survey ZOL effectively reduced this risk.

Hemangioblastomas of central nervous system: molecular genetic analysis and clinical management.

Abstract: Objective Hemangioblastomas of the central nervous system (CNS) are benign neoplasms that may occur sporadically or in association with von Hippel-Lindau (VHL) disease. The proportion of primary symptomatic hemangioblastomas associated with VHL disease is estimated to be from 10 to 40%, but it seems to be underestimated. We investigated the frequency of VHL germline mutation in patients with symptomatic CNS hemangioblastoma without evidence of VHL disease to define the role of molecular genetic analysis in the management of such patients and their relatives. Methods We analyzed 14 patients (6 female and 8 male; mean age, 43.5 yr) with no family history and no other clinical manifestations of VHL disease who had been operated on for symptomatic CNS hemangioblastoma. Exons 1, 2, and 3 of the VHL gene and their immediately flanking sequences were amplified by use of polymerase chain reaction followed by analysis with denaturing high-performance liquid chromatography and sequencing the anomalous samples. Results Germline mutations of the VHL gene were identified in 2 (14%) of 14 patients. VHL gene mutation analysis was performed in both patients' family members, which showed another affected asymptomatic subject for VHL disease. The affected subjects were recommended for VHL disease surveillance protocol. Conclusion Molecular genetic analysis is a safer and more specific instrument to confirm or exclude VHL disease in patients with CNS hemangioblastoma, a negative family history, or absence of other known manifestations of the disease. Early identification of VHL mutation gene carriers is important for reducing disease morbidity and mortality. Nonsymptomatic family members will benefit from early VHL disease diagnosis or by being excluded as at-risk subjects, reducing the psychological and economic burden of screening and surveillance protocols.
