Cervical cancer patients with high expression of CBX8 and PD-L1 have a poor prognosis (five-year survival rate of only 46.2%), while cervical cancer patients with low expression of CBX8 and PD-L1 have a better prognosis (a five-year survival rate of 96%) (Fig. 4A). The gene discussed is CBX8; the disease is cervical carcinoma.
