XPF protein expression was detected by immunohistochemical staining. We conducted a Mann\u2013Whitney U test in order to explore the differential expression of XPF between CRC and non-cancer controls, and the correlation between XPF expression and CRC clinicopathological parameters. Univariate and multivariate Cox regression analyses were conducted to investigate the relationship between XPF expression and CRC prognosis.

XPF protein was increased in the dynamic sequence of anal diseases to adenoma tissue to CRC. Expression of XPF was related to tumor location (P\u2009=\u20090.005) and tumor growth pattern (P\u2009=\u20090.009). The results of prognosis analysis suggested that in patients with stage T1-T2, XPF low expression may be significantly associated with better overall survival (HR\u2009=\u20097.978, 95% CI 1.208\u201352.673, P\u2009=\u20090.031). XPF and its interacting genes played a vital role in different processes of nucleotide excision repair pathway.
