What genomic alterations (i.e. driver events) does the NCCN identify for non-small cell lung cancer (NSCLC)? And what targeted agents does the NCCN recommend for these specific driver events?

Based on clinical data and FDA approvals, why do NCCN guidelines for NSCLC recommend erlotinib and gefitinib as first-line systemic therapy in patients with sensitizing EGFR mutations?

Based on published clinical data and FDA approvals, why do NCCN guidelines for NSCLC recommend erlotinib and gefitinib as recommended (category 1) first-line systemic therapy in patients with sensitizing EGFR mutations?

In what kind of solid tumors can comprehensive genomic profiling/NGS make a difference in identifying patients with EGFR and other mutations that may be missed by hotspot tests? (Korean)

In what kind of solid tumors, specifically NSCLC, can comprehensive genomic profiling/NGS make a difference in identifying patients with EGFR and other mutations—ALK, MET, ROS-1—that may be missed by hotspot tests?

What is the importance of the gene encoding the ROS1 proto-oncogene receptor tyrosine kinase as a distinct molecular subgroup of NSCLC? In what percentage of patients is ROS1 detected?

What is the importance of NGS for finding EGFR sensitizing mutations such as exon 19 or exon 21 in NSCLC? What is their relationship to sensitivity to TKIs, such as erlotinib, gefitinib, and afatinib?
