Recent studies have shown that a variety of ncRNAs mediate the expression of EGFR in GC, so these ncRNAs can be used as a medium to target and regulate the expression of EGFR, and then promote the apoptosis of GC cells in the process of radiotherapy, thereby improving the sensitivity of GC to radiotherapy (Carlomagno et al., 2017; D'Souza et al., 2020; Kong et al., 2021; Ye et al., 2022; Lazăr et al., 2016) (Figure 2). Here, EGFR is linked to gastric cancer.
