Showing 1 - 6Osimertinib Resistance Mechanisms in EGFR T790M–Positive NSCLC
In a study reported in JAMA Oncology, Oxnard et al found early resistance and a number of competing resistance mechanisms in acquired osimertinib (Tagrisso) resistance associated with loss of the T790M mutation conferring resistance to prior EGFR tyrosine kinase inhibitor (TKI) treatment in...
Geoffrey R. Oxnard, MD, on Lung Cancer: Results From the Circulating Cancer Genome Atlas Study
Geoffrey R. Oxnard, MD, of Dana-Farber Cancer Institute, discusses genome-wide sequencing for early-stage lung cancer detection from plasma cell–free DNA (Abstract LBA8501).
2018 ASCO: Blood Test Shows Potential as a Detection Tool for Early-Stage Lung Cancer
An initial report from the large, ongoing Circulating Cell-Free Genome Atlas (CCGA) study provides preliminary evidence that a blood test may be able to detect early-stage lung cancer. This is one of the first studies to explore blood tests analyzing free-floating or cell-free DNA as a tool for the ...
Plasma vs Tissue Genotyping and Outcomes With Osimertinib in Advanced Non–Small Cell Lung Cancer
Patients with advanced non–small cell lung cancer (NSCLC) positive for the epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor T790M resistance mutation on a plasma assay had similar outcomes with the EGFR tyrosine kinase inhibitor osimertinib (Tagrisso) as did those who were...
Validation of Rapid Plasma Genotyping for Detecting EGFR and KRAS Mutations in Advanced Lung Cancer
As reported in JAMA Oncology, Sacher et al have prospectively validated a plasma droplet digital polymerase chain reaction (ddPCR) assay for detecting common EGFR and KRAS mutations in patients with advanced nonsquamous non–small cell lung cancer. Study Details The study involved 180...
Study Finds NSCLC to Be Genetically Different in Younger and Older Patients, Requiring Different Treatment Approaches
Unlike a number of other cancers in which young age at diagnosis is understood to represent distinct disease biology, the genomics and clinical characteristics of non–small cell lung cancer (NSCLC) in young patients are poorly understood. A study by Sacher et al investigating the relationship ...
