The results of multivariate analysis also showed that preoperative SOD < 58.055 U/mL and SUA ≥ 312.770 mmol/L and TNM staging III-IV were independent risk factors affecting the postoperative prognosis of patients, indicating that the prognosis of these liver cancer patients after radical resection may be poor and the survival time may be shortened. The gene discussed is SOD1; the disease is liver cancer.
