To confirm the correlation of IRGPI with PD-L1 expression in CESC, we selected 23 patients with cervical cancer who had PD-L1 test reports and were treated with anti-PD-L1, and statistically analyzed the correlation between PD-L1 expression and Epigen, LCN10 and P73 expression (PD-L1 CPS score <3 was negative; CPS score >3 is positive). The gene discussed is TP73; the disease is cervical cancer.
