There were three major deficiencies in this study: (1) The survival prognosis model established in this study was based on single‐center data, and only conducted internal validation without external validation; (2) The time span of the cases included in this study was long, which resulted in heterogeneity of the cases; (3) Preoperative tumor markers, Ki‐67, P53 and other pathological indicators were not included in this study. Here, MKI67 is linked to neoplasm.
