ABSTRACT
Objective:To analyze the value of laminin γ2 (LAMC2) in the diagnosis of hepatocellular carcinoma (HCC) and the difference in patients with different types of microvascular invasion (MVI).Methods:A cohort of 100 patients with HCC who underwent surgical treatment at the Faculty of Hepato-Pancreato-Biliary Surgery, Chinese PLA General Hospital from January 2021 to March 2022 were prospectively enrolled. There were 80 males and 20 females, aged (55.7±11.1) years. The data of 17 patients with hepatic hemangioma without cirrhosis who underwent operation at the same hospital during the study period were collected to serve as the control group (6 males, 11 females), aged (42.8±9.8) years. LAMC2 in serum was determined by enzyme linked immunosorbent assay. The levels of alpha-fetoprotein (AFP) and LAMC2 were compared between the two groups, and receiver operating characteristic (ROC) curves were drawn to compare these two markers in the diagnosis of HCC. The LAMC2 of different MVI patients were compared.Results:The levels of LAMC2 and AFP were 1 334.2(838.9, 2 656.0) pg/ml and 19.0(4.6, 778.6) μg/L in the HCC group, which were significantly higher than 375.2(221.2, 691.7)pg/ml and 3.3(2.5, 3.5) μg/L in the control group ( Z=-4.32, -4.63, both P<0.001). The areas under the ROC curve were 0.829(95% CI: 0.748-0.892) for LAMC2 and 0.852(95% CI: 0.769-0.910) for AFP, and was 0.949(95% CI: 0.911-0.988) for using both in the diagnoses. The diagnostic efficacy of combining LAMC2 and AFP was significantly better than that of LAMC2 alone and AFP alone (area under ROC: Z=3.15, 3.07, P=0.002, 0.002). When the patients were divided into the M0 group (61 patients), the M1 Group (25 patients) and the M2 Group (14 patients) based on MVIs, the concentrations of LAMC2 were 1 168.6(834.3, 2 521.4) pg/ml, 942.2(614.0, 2 056.6) pg/ml and 3 128.4(1 852.7, 7 191.3) pg/ml, respectively. The level of LAMC2 in the M2 group was significantly higher than that in the M0 and M1 groups ( Z=-3.46, -3.32, P=0.001, 0.004). Conclusion:The diagnostic efficacy of LAMC2 combined with AFP for HCC was significantly higher than that of either LAMC2 alone or AFP alone. Serum LAMC2 levels were significant different among the groups of HCC patients with different types of MVI.
