STRN-ALK Fusion in a Case of Malignant Peritoneal Mesothelioma: Mixed Response to Crizotinib, Mode of Resistance, and Brigatinib Sequential Therapy

To our knowledge, this is the first description of an STRN-ALK fusion(+) MPM sequentially treated with two different ALK inhibitors. This case underlines the benefit of molecular testing in MPM. Furthermore, it suggests the generalizability of the lessons learned from lung cancer to another entity, which can offer some guidance in the treatment of this rare disease. READ ARTICLE

Primary resistance to alectinib in a patient with STRN-ALK-positive non-small cell lung cancer: A case report

naplastic lymphoma kinase (ALK) rearrangements are drivers of a subset of non-small cell lung cancer (NSCLC). The rapid progression of ALK inhibitors has significantly prolonged the progression-free survival of patients with ALK gene-sensitive mutations. However, the response of patients with rare ALK rearrangements to tyrosine kinase inhibitors remains unknown. Here, we report a rare case of striatin (STRN)-ALK-positive NSCLC showing primary resistance to first-line therapy alectinib and limited clinical activity of crizotinib in the alectinib-resistant setting.

Identification and Development of a Lung Adenocarcinoma PDX Model With STRN-ALK Fusion

Gene fusions involving the anaplastic lymphoma kinase gene (ALK) often leads to oncogenic activation of the ALK kinase resulting in tumor development in lung and other solid tumors. Accurate identification of the fusion gene in patients with lung cancer has profoundly impacted patients’ clinical performance and long-term survival. READ ARTICLE
