Disease & Epidemiology Analysis

Lung cancer remains one of the leading causes of cancer-related mortality worldwide because many patients receive diagnoses after disease progression has reached advanced stages. Non-small cell lung cancer (NSCLC) represents approximately 85% of all lung cancer cases, making it the primary focus of companion diagnostic development. Small cell lung cancer (SCLC) accounts for a smaller proportion but continues to present significant unmet clinical needs due to its aggressive biological behavior.

The molecular landscape of NSCLC continues expanding beyond traditional EGFR and ALK alterations as additional actionable biomarkers enter routine clinical practice. KRAS mutations, particularly KRAS G12C, have become clinically relevant following targeted therapy approvals. ROS1 rearrangements, BRAF V600E mutations, RET fusions, MET exon 14 skipping alterations, HER2 mutations, and NTRK fusions are also contributing to increasingly individualized treatment selection. Comprehensive genomic profiling is therefore becoming essential during initial diagnosis because multiple biomarkers may influence first-line therapeutic decisions.

Global tobacco exposure remains the predominant risk factor for lung cancer, although the increasing incidence among never-smokers is emphasizing the biological importance of oncogenic driver mutations. Younger patients and individuals with limited smoking history frequently present with actionable genomic alterations that respond to targeted therapies. This epidemiological shift is reinforcing demand for universal biomarker testing regardless of traditional clinical risk factors.
