Multiomic characterization of small cell lung cancer: Real-world insights into therapeutic opportunities.

ABSTRACT:

Background

The dominant expression of lineage-related transcription factors (TFs)-ASCL1, NEUROD1, POU2F3, and, controversially, YAP1-has enabled the classification of small cell lung cancer (SCLC) into distinct subtypes (SCLC-A/N/P/Y, respectively). Emerging evidence suggests that a T cell-inflamed phenotype characterizes an SCLC subset. A large-scale multiomic analysis of samples from real-world patients with SCLC was conducted to examine the expression of clinically relevant biomarkers across SCLC subtypes.

Methods

Comprehensive molecular profiling of patient samples (N = 944) was performed via next-generation DNA sequencing (592-gene panel or whole exome), RNA sequencing (whole transcriptome), and immunohistochemistry. Tumors were stratified on the basis of the dominant e
