In particular, high CYP4X1 expression was associated with various factors such as TNM stage, tumor differentiation, depth of invasion, lymph node metastasis, and distant metastasis, as shown through chi-square analysis, Mann–Whitney U/Kruskal–Wallis H test analysis, and Cox regression univariate/multivariate analysis. The gene discussed is CYP4X1; the disease is neoplasm.
