As a result, in all 1411 cases, high FAF1 expression was significantly associated with poor prognosis (p = 0.0011), a similar result was shown in the adenocarcinoma cohort (n = 672, p = 0.027), but not in the squamous cell carcinoma cohort (n = 527, p = 0.52) (Figure S2). This evidence concerns the gene FAF1 and squamous cell carcinoma.
