Overview of Late-Stage Metastatic EGFR-Positive Non-Small Cell Lung Cancer

Dr. Kartik Konduri introduces the program on patient experiences with EGFR-positive NSCLC, joined by Elizabeth Dennis, an advanced practice provider at Texas Oncology at Baylor Simmons Cancer Center, and Lynn Abbott-McCloud, Executive Director of LiveLung, a nonprofit lung cancer organization.

Dr. Konduri provides a disease overview. EGFR mutated-positive NSCLC accounts for approximately 10% to 15% of non-small cell lung cancer diagnoses in the United States, representing approximately 30,000 to 35,000 cases annually. Although most cases are detected at late stage, expanded lung cancer screening is enabling earlier-stage detection in some patients. Lung cancer staging from stage 1 through stage 4 drives tailored treatment selection, with targeted therapies representing a particular strength in the EGFR-positive subset.

A defining feature of EGFR-positive NSCLC is its distinct patient population. Unlike smoking-related lung cancer, EGFR mutations are disproportionately found in light or never smokers, younger patients, females, and individuals of East Asian ancestry. This has significant practical implications: these patients frequently fall outside standard lung cancer screening criteria, meaning lung cancer is often not on the clinical radar for patients or their primary care physicians when symptoms first arise.

Elizabeth Dennis describes the diagnostic journey these patients typically experience. Symptoms such as persistent cough, fatigue, shortness of breath, and unintentional weight loss often overlap with common benign conditions, leading to initial diagnoses of allergies, bronchitis, or asthma. Lynn Abbott-McCloud adds that the diagnosis is typically a shock, and that incidental findings, including lung cancer discovered on imaging obtained for an unrelated reason such as a car accident or a fall, are not uncommon in the EGFR community. Diagnostic delays of up to 12 months before a computed tomography (CT) scan is obtained are a real pattern and represent an area of ongoing advocacy concern.
