RPA3 and squamous cell lung carcinoma: Further subgroup analysis showed that in 673 patients with lung adenocarcinoma, high RPA3 expression levels had a significant effect on OS (HR=2.38, logrankP=3.3e-12, Figure 5B), whereas in 271 patients with lung squamous cell carcinoma, Its high expression level had no significant effect on OS (HR=0.73, logrankP=0.052, Figure 5C).
