Furthermore, we found that 17% of the tumors had mutations in PIK3CA and FBXW7 without mutation of typical driver genes, such as KRAS, TP53, and EGFR, as reported in other cervical cancer genome studies 13, 31; these were not found in our study, which suggests that they may be the later‐stage events. This evidence concerns the gene KRAS and cervical carcinoma.
