Serum SALL4 as a predictive biomarker for the prognosis of patients with hepatocellular carcinoma who underwent nonsurgical treatment

To investigate the role of serum spalt like transcription factor 4 (SALL4) in the hepatocellular carcinoma (HCC) patients with nonsurgical treatment. Serum samples were collected from 101 patients with HCC without surgical treatment, then the SALL4 was detected by enzyme linked immunosorbent assay. According to subsequent treatment, patients were divided into 2 groups, best supportive care (BSC) (58 cases) and nonsurgical anticancer treatment (NSAT) (48 cases). Kaplan–Meier survival analysis and Cox multivariate regression analysis were applied to evaluate the relationship between SALL4 and survival time of 2 groups. In BSC group, there was no significant difference of the survival time between 2 groups (SALL4 < 800 ng/mL or SALL4 ≥ 800 ng/mL) (P = .339). In NSAT group, the survival time of patients with low SALL4 concentration was significantly longer than patients with high SALL4 concentration (P = .005). SALL4 have no predictive effect in BSC patients with HCC. But for patients received NSAT, low SALL4 concentration in serum may indicate longer survival.
