Univariate analysis demonstrated that significant association was observed between mOS and PS (P < 0.001), gender (P = 0.007), tumor differentiation grade stage (P = 0.005), JWA (P < 0.001) or XRCC1 (P < 0.001) mRNA expression in the whole cohort (Tables 2 and 3). The gene discussed is XRCC1; the disease is neoplasm.
