- Abstract: Objective To investigate the levels of plasma bile acids(BA)in patients with primary liver cancer(PLC)or metastatic liver cancer(MLC)and their correlation with clinical indicators,as well as the value of plasma BAs combined with alpha-fetoprotein(AFP)in the diagnosis of PLC.Methods This study was conducted among 75 patients with PLC and 79 patients with MLC who attended Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from August 2020 to September 2021 and had a confirmed diagnosis based on histopathological and imaging findings.Peripheral blood samples were collected from all patients,and serum and plasma were separated.Colorimetry and chromatography were used to measure biochemical parameters;electrochemiluminescence immunoassay was used to measure the levels of tumor markers;liquid chromatography-tandem mass spectrometry was used to measure the content of BA.The t-test was used for comparison of normally distributed continuous data,and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data;the Spearman's coefficient was used for correlation analysis;the receiver operating characteristic(ROC)curve was used to evaluate clinical diagnostic efficacy.Results The PLC group had significantly lower levels of total cholesterol,triglyceride,low-density lipoprotein cholesterol,and apolipoprotein B than the MLC group(U=1 598,1 255,909,and 889,all P＜0.05).Compared with the MLC group,the PLC group had a significantly higher level of AFP and a significantly lower level of carcinoembryonic antigen(U=1 873 and 926,both P＜0.05).Compared with the MLC group,the PLC group had significantly higher levels of TBA,CA,CDCA,UDCA,TCA,TCDCA,GCA,GCDCA,TUDCA,and GUDCA and a significantly lower level of DCA(all P＜0.05).In the total population,the levels of TBA,CDCA,GCA,GCDCA,GUDCA,TCA,TCDCA,and TUDCA were significantly positively correlated with the level of AFP(all P＜0.05).In the patients with PLC,the levels of GCA,TCA,TCDCA,and TUDCA were significantly positively correlated with the level of AFP(all P＜0.05).Combined measurement of AFP+TCA+GCA+TCDCA had an area under the ROC curve of 0.822(95%confidence interval:0.746-0.898,P＜0.000 1),suggesting that it had the highest diagnostic efficacy.Conclusion There are significant differences in the levels of plasma BA between the patients with PLC and those with MLC,and the differentially expressed BAs are closely associated with liver function impairment and the increase in AFP.BAs combined with AFP has a better clinical value in the diagnosis of PLC.
