Predictive Genes

Published on August 31, 2018

Most patients with thin, early melanomas do very well, having a relatively
low risk of disease spread or re-occurrence. However some of these “low
risk” patients are not so lucky and end up with re-occurrence, or
metastasis. In an effort to better predict which of the “low risk” patients
were likely to be in this less fortunate sub-group, investigators used a
31-gene expression profile (31-GEP). The results suggest that the 31-GEP
test may help identify high-risk individuals within groups previously
considered to be low-risk. This could alert the patient and their treating
physicians for the need for more careful follow up and even to consider
adjunct treatment. Larger prospective studies will be needed to better
understand how and when to use these test and what to do with the results.
None the less it is getting us one step closer to better predicting patients
risk and so will ultimately help guide management.
