Many studies have shown that the JAK/STATs, MAPK/ERK and PI3K/AKT pathways are aberrantly activated in EGFR‐expressed tumour cells, which is thought to be responsible for cancer cell growth and metastasis (Tang et al., 2019; van der Mijn et al., 2014; Yang, Qian, Li, Li, & Han, 2018; Zhao & Hu, 2013). The gene discussed is EGFR; the disease is neoplasm.
