Successful oral desensitization with crizotinib after crizotinib-induced hepatitis in an anaplastic lymphoma kinase-rearranged non-small-cell lung cancer patient: A case report.

ABSTRACT: Crizotinib is one of the molecularly-targeted agents targeted against anaplastic lymphoma kinase (ALK)-rearranged non-small-cell lung cancer (NSCLC). Although its effects appear to be promising, crizotinib may cause adverse effects in patients with ALK-rearranged NSCLC. Hepatic laboratory abnormalities are frequently observed with crizotinib and treatment discontinuation is occasionally required. We herein report the case of a 51-year-old woman diagnosed with relapsed ALK-rearranged NSCLC, who received crizotinib as second-line systemic chemotherapy. After 17 days of crizotinib therapy, the patient developed grade >3 hepatotoxicity. Treatment discontinuation improved the laboratory abnormalities and fifth-line oral desensitization with crizotinib achieved successful response without hepatotoxicity. Therefore, oral desensitization with crizotinib may be a viable option following crizotinib-induced hepatitis.
