“…Several studies have identified multiple gene expression subtypes that differ in prognosis, genomic alterations, clinical characteristics, including tumor differentiation, stage-specific survival, underlying drivers, and potential responses to treatment within LUAD and SCLC (Wilkerson et al, 2010;Thomas et al, 2014;Lu et al, 2016). For example, LUAD patients that harbor EGFR, ALK, ROS1, or BRAF mutations were discovered to benefit the most (Villalobos and Wistuba, 2017;Herbst et al, 2018). Targeted therapies for gene abnormalities of HER2, MET, RET, and NTRK1 appear to be an effective approach to treat LUAD (Dearden et al, 2013;Mazieres et al, 2013).…”
