For example, increased EGFR expression is associated with increased tumor chemoresistance and radioresistance in tumors, including squamous cell carcinoma, ovarian adenocarcinoma, hepatocarcinoma, glioblastoma, and adenosquamous carcinoma of the cervix (Akimoto et al., 1999; Milas et al., 2000; Nasu et al., 2001; Wang et al., 2020a). Here, EGFR is linked to glioblastoma.
