Abstract:
Objective
To analyze the changing trends of serum Golgi protein 73 (GP73) before and after TACE for primary liver cancer (PLC) and its correlation with efficacy of TACE,aiming to explore the role of serum GP73 level in the evaluation of efficacy of TACE.
Methods
In this prospective study,51 patients with PLC who underwent TACE in the First Affiliated Hospital of Xinjiang Medical University from September 2020 to May 2021 were enrolled. The informed consents of all patients were obtained and the local ethical committee approval was received. Among them,45 patients were male and 6 female,aged 42-86 years,with a median age of 61 years. 50 healthy subjects were selected as normal controls.The efficacy of TACE was evaluated based on the modified response evaluation criteria in solid tumors(mRECIST). According to efficacy,all patients were divided into the favorable efficacy group (n=18) and poor efficacy group (n=33). Serum GP73 levels 1 d before TACE and 1,3,5,7 and 30 d after TACE were detected by ELISA. Serum GP73 levels between patients and normal controls were compared by t test.The effect of GP73 expression on TACE efficacy was evaluated by generalized estimation equation of repeated measurement data. Correlation analysis was performed by Pearson's and Spearman's correlation analyses.
Results
The average expression level of GP73 in PLC patients before TACE was (0.39±0.25) IU/ml,significantly higher than (0.03±0.01) IU/ml in normal controls (t=10.841, P<0.05). The expression level of GP73 at 1 d after TACE was significantly higher than preoperative level,which was decreased continuously at 3,5 and 7 d after TACE. In the favorable efficacy group,the average expression level of GP73 at postoperative 7 d was significantly lower compared with preoperative level,whereas the expression level of GP73 at postoperative 7 d was similar to that before TACE in the poor efficacy group.In the favorable efficacy group,the average expression level of GP73 at 30 d after TACE was further decreased compared with those before and 7 d after TACE,whereas the expression level of GP73 at 30 d after TACE was significantly higher than those before and 7 d after TACE in the poor efficacy group.There was an evident interaction effect between the efficacy and duration of TACE (F=15.037, P<0.05).There was statistical significance in the expression levels of GP73 at postoperative 5 and 30 d between the favorable and poor efficacy groups (t=4.987,26.788; P<0.05). A significant negative correlation was found between the changes of GP73 levels before and 30 d after TACE and efficacy of TACE (rs=-0.687, P<0.05).An evident positive correlation was found between preoperative GP73 level and tumor diameter (r=0.543,P<0.05).
Conclusions
A significant negative correlation is found between the changes of GP73 levels before and after TACE and efficacy of TACE. The greater the decrease of GP73 levels at postoperative 1 month after TACE,the better the efficacy. GP73 level has potential value in evaluating the efficacy of TACE.
