At multivariate analysis including CYP2W1 levels, ENSAT tumor stage, and Ki67 proliferation index, the impact of CYP2W1 expression on both OS and TTP was statistically significant (HR = 3.9, P = 0.009 and HR = 4.9, P = 0.001, respectively, Table 2). The gene discussed is CYP2W1; the disease is neoplasm.
