CYP1A1 and cervical cancer: Analysis of AHR, CYP1A1, HSP90AA1, HSP90AB1 and ESR1 using the Cox multivariate regression model and the forward stepwise regression method (inclusion: P < 0.05, exclusion: P> 0.1) showed that high expression of AHR (HR = 1.874, 95% CI = 1.069–3.285, P= 0.028) and CYP1A1 (HR = 1.822, 95%CI = 1.077–3.080, P= 0.025) was a risk factor for the prognosis of patients with cervical cancer (Table 3, Figure 7).
