|Title||Response to lorlatinib on a patient with ALK-rearranged non-small cell lung cancer harboring 1151Tins mutation with uterine metastasis.|
|Abstract Text||We describe a case of an anaplastic lymphoma kinase (ALK)-rearranged non-small cell lung cancer with development of uterine metastasis after crizotinib and alectinib treatment. Gene analysis from the tissue of uterine metastasis revealed the presence of 1151Tins, which was considered to be a crizotinib and alectinib resistance mutation. Subsequent therapy with the third-generation ALK inhibitor lorlatinib, but not ceritinib, showed antitumor activity for 1 year. The uterus is an uncommon site for metastasis from lung cancer, and our case indicated that serial gene analysis could provide new information about ALK inhibitor resistance.|

|ALK fusion ALK T1151dup||lung non-small cell carcinoma||predicted - sensitive||Lorlatinib||Case Reports/Case Series||Actionable||In a clinical case study, Lorbrena (lorlatinib) treatment resulted in shrinkage of the pulmonary and uterine lesions in a patient with non-small cell lung cancer and uterine metastasis harboring an ALK fusion and ALK T1151dup (reported as ALK 1151Tins), and the patient remained recurrence-free over 1 year of treatment (PMID: 34184417).||34184417|
|ALK fusion ALK T1151dup||lung non-small cell carcinoma||no benefit||Ceritinib||Case Reports/Case Series||Actionable||In a clinical case study, Zykadia (ceritinib) treatment did not result in disease control in a patient with non-small cell lung cancer and uterine metastasis harboring an ALK fusion and ALK T1151dup (reported as ALK 1151Tins) whose disease progressed after prior Xalkori (crizotinib) and Alecensa (alectinib) treatments (PMID: 34184417).||34184417|
