Transcriptomic Subtypes Are Associated with Clinical Outcomes for Patients with Lung Adenocarcinoma Who Have Never Smoked

Lung adenocarcinoma arising in individuals who have never smoked is understudied, represents a substantial global health burden, and is genomically distinct from smoking-associated disease. Zhao and colleagues have identified transcriptomic subtypes with prognostic value, including in stage I disease, supporting phenotypic state as an important determinant of outcome for lung adenocarcinoma in individuals who have never smoked.
