Neurofibromatosis type 1 adult surveillance form for Austria

Abstract

Background

Neurofibromatosis type 1 (NF1) is a rare autosomal dominant tumor predisposition syndrome with a birth prevalence of approximately 1 in 2000–3000 individuals. Management of both benign and malignant tumors arising in individuals with NF1 is demanding and tumors may be difficult to treat. Both standardized and individual surveillance programs are therefore highly important to prevent morbidity and mortality in patients with NF1.

Methods

The guidelines for the clinical management of NF1 recently proposed by the European Reference Network for Genetic Tumor Risk Syndromes provide the cornerstone of the present surveillance form and were discussed through three rounds of voting and a final consensus meeting involving experts from five Austrian and one German clinical NF1 centers for adults and one patient organization representative. Subsequently, 31 items within 4 categories were integrated into the proposed surveillance form for Austria. All recommendations, unless otherwise specified, pertain to primarily asymptomatic patients in routine follow-up.

Recommendations

At healthcare transition from pediatric to adult surveillance or the initial visit in adulthood, we suggest a thorough clinical, laboratory and radiological examination to obtain a baseline for future diagnostics. To comply with the general screening recommendations in Austria, we suggest extending the frequency of clinical visits from annual to biennial at 50 years of age. In cases of clinical dynamics, early follow-up is recommended to facilitate early detection of potential complications. Particular emphasis should be placed on preventive patient education.
