Alectinib-induced rash unresponsive to desensitization: a case report and literature review.

Background: Since the inception of targeted therapies in treating lung cancer, providers have had to be aware of a new host of side effects when selecting management options for patients. Although targeted therapies are creating increased hope for patients with non-small cell lung cancers (NSCLC), understanding their side effects presents a challenge for providers. Alectinib, a second-generation tyrosine kinase inhibitor, is a targeted therapy used in patients with non-small cell lung cancer found to have anaplastic lymphoma kinase (ALK) mutations.
