Although alectinib is a well-tolerated and highly effective inhibitor of a second-generation anaplastic lymphoma kinase, special attention should be paid to the possibility of potentially severe and fatal adverse events such as interstitial pneumonia. We report a case of a patient with advanced non-small cell lung cancer treated with alectinib who developed immunohistochemically positive anaplastic lymphoma kinase (ALK(IHC +)) . However, due to the rapid emergence of drug-induced interstitial lung disease, alectinib treatment was halted. Once the interstitial lung disease had been successfully treated, we reluctantly chose crizotinib as a second-line treatment for ALK + NSCLC in this patient as he refused all other available treatments. Contrary to expectation, crizotinib performed well both in terms of its safety and efficacy. Our results suggest that crizotinib may provide a promising therapy option for patients with ALK + NSCLC accompanied by alectinib-induced interstitial lung dise..... READ ARTICLE
