Moreover, the overexpression of RFC4, EXO1, PCNA, TOP2A, and TYMS demonstrated a correlation with a more favorable prognosis in patients diagnosed with cervical cancer, as determined through log-rank test and hazard ratio (HR) p-values of less than 0.05 (refer to Table 2 and Additional file 1: Fig. S1). The gene discussed is PCNA; the disease is cervical cancer.
