In addition, anaplastic lymphoma kinase (ALK) and ROS proto-oncogene 1 (ROS1) fusions have been demonstrated to be effectively druggable with targeted inhibitors such as crizotinib, alectinib, and ceritinib and are currently recommended for the treatment of advanced stage adenocarcinoma harbouring that kind of genetic alteration [8–10]. The gene discussed is ALK; the disease is adenocarcinoma.
