The ALK gene (anaplastic lymphoma kinase) encodes a highly conserved tyrosine kinase receptor whose physiological function has not yet been fully established; in particular the fusion of ALK (mainly EML4-ALK) is the gene alteration that most frequently involves 3-7% of all non-small cell lung cancers.

Abstract

The ALK gene (anaplastic lymphoma kinase) encodes a highly conserved tyrosine kinase receptor whose physiological function has not yet been fully established; in particular the fusion of ALK (mainly EML4-ALK) is the gene alteration that most frequently involves 3-7% of all non-small cell lung cancers. Neuroblastoma in adults (NB) is a rare tumor that can present somatic activating mutations in the ALK gene in 8-9% of patients (and up to 14% of high-risk NBs); these mutations occur in the tyrosine kinase domain in three key positions (F1174, F1245 and R1275), which account for approximately 85% of all ALK mutations in NB. In this article, we report the case of an adult patient with advanced mutation-positive NB treated with an ALK inhibitor ceritinib showing a therapeutic opportunity due to the molecular diagnostic techniques now available.
