A new tool may help physicians predict the outcome of people with ALS. The personalized approach, developed by a research team led by UMC Utretcht’s Leonard van den Berg in Amsterdam, uses 8 factors to estimate survival time including age and site of onset, breathing ability (FVC), the presence (or absence) of a C9orf72 repeat expansion and progression rate.
The strategy is based on the analysis of medical records of nearly 11,500 people with ALS obtained from 14 clinics in 9 countries in Europe.
The approach estimated the survival time of people with ALS upon the day of diagnosis at a probability of more than 98% of good performance (c-statistic = 0.78). The inclusion in future of surgical interventions and treatments including riluzole use is anticipated to further improve predictions (Westeneng et al., 2018; see also Fang et al., 2018).
The computational approach is one of a growing number of strategies that aims to help forecast the prognosis of people with ALS by predicting the rate of progression and/or outcome of the disease (see April 2017, November 2017 news).
The study appeared on March 26 in Lancet Neurology.
The online tool is available to neurologists at no cost. The approach may also facilitate testing of ALS drug candidates in the clinic in part, by helping to stratify participants and identify “responders” that may benefit from these potential therapies (see April 2017 news).
