The clinical manifestation was found to be more serious in affected offspring of VHL patients, but the risk factors and survival for them has never been reported before. We aimed to explore how these patients were influenced by genetic and clinical factors. METHODS: In this retrospective study, we collected 372 affected offspring of VHL patients from 118 unrelated VHL families. Patients were stratified into different groups based on sets of variables. The age-related risk, overall survival and central nervous system haemangioblastoma (CHB)-specific survival were analyzed between different groups using Kaplan-Meier survival analysis and Cox regression analysis. RESULTS: The estimated median life expectancy and median onset age for affected offspring of VHL patients was 66 years and 28 years respectively. The later generation and patients with mutations in exon 3 had an earlier onset age. The first presenting symptom was the only independent risk factor influencing overall survival and CHB-specific survival. Patients that the first presenting symptom is CNS significantly had a lower life expectancy both in overall survival and CHB-specific survival analysis. CONCLUSIONS: This study indicated that affected offspring of VHL patients with CNS as the first presenting symptom was an independent risk factor for overall survival and CHB-specific survival, which is helpful to clinical decision-making and generate a more precise surveillance protocol.
