INTRODUCTION MET proto-oncogene, receptor tyrosine kinase gene exon 14 skipping (METex14) alterations represent a unique subset of oncogenic drivers in NSCLC. Preliminary clinical activity of crizotinib against METex14-positive NSCLC has been reported. The full spectrum of resistance mechanisms to crizotinib in METex14-positive NSCLC remains to be(More)
A number of small molecule tyrosine kinase inhibitors (TKIs) have now been approved for the treatment of non-small cell lung cancers (NSCLC), including those targeted against epidermal growth factor receptor, anaplastic lymphoma kinase, and ROS1. Despite a wealth of agents developed to target the receptor tyrosine kinase, MET, clinical outcomes have as yet(More)
INTRODUCTION Patients with anaplastic lymphoma kinase (ALK)-rearranged non-small cell lung cancer (NSCLC) may derive significant clinical benefit from targeted therapies against this driver mutation, but progression is virtually inevitable. Alectinib is a next-generation ALK inhibitor that provides a novel treatment option for this group of patients. Areas(More)
Patients with anaplastic lymphoma kinase (ALK)-rearranged non-small cell lung cancer (NSCLC) derive significant clinic benefit from treatment with ALK inhibitors. Crizotinib was the first approved tyrosine kinase inhibitor (TKI) for this distinct molecular subset of NSCLC. Disease progression on TKI inevitably arises secondary to diverse resistance(More)
Crizotinib was approved for the treatment of ROS1-rearranged non-small cell lung cancer (NSCLC) patients in the US on 11 March, 2016. Interestingly no one companion diagnostic test (CDx) has been approved simultaneously with this approval of crizotinib. Hence, an ideal and adequate CDx will have to be able to identify ROS1 fusions without the knowledge of(More)
Acquired epidermal growth factor receptor (EGFR) resistance mutations to osimertinib are common, including the EGFR C797S that abolishes the covalent binding of osimertinib to EGFR. Here we report the emergence of novel EGFR solvent front mutations at Gly796 (G796S/R) in addition to a hinge pocket L792F/H mutations, and C797S/G all in cis with T790M in a(More)
Lynch syndrome (hereditary nonpolyposis colorectal cancer) is an autosomal dominant disorder characterized by a significant risk of colorectal and endometrial cancers. A variety of other epithelial cancers may be associated with this syndrome. Brian tumors are infrequent, but have been reported in series. Here, we report a case of a 34-year-old Caucasian(More)
Development of the acquired ALK G1202R solvent front mutation and small cell lung cancer (SCLC) transformation have both been independently reported as resistance mechanisms to ALK inhibitors in ALK-rearranged (ALK+) non-small cell lung cancer (NSCLC) patients but have not been reported in the same patient. Here we report an ALK+ NSCLC patient who had(More)
