Abstract:

Objective

To construct a preoperative prediction model for microvascular invasion(MVI) of hepatocellular carcinoma (HCC) based on Meta-analysis.

Methods

Studies related to prediction model for MVI of HCC published at home and abroad was retrieved.The retrieval results were screened and the data were extracted.The quality of included studies was assessed by Newcastle-Ottawa Scale (NOS).Meta-analysis was carried out for the included studies.The risk factors with significant combined effects were extracted and the risk values were combined according to the results.The prediction model was constructed and a nomogram was delineated.64 HCC patients undergoing surgery in Chifeng Municipal Hospital from January 2020 to January 2023 were selected into the model validation set.The prediction performance of this model was evaluated by the area under the ROC curve (AUC).The accuracy and clinical practicability of this model were analyzed by the calibration curve and decision curve analysis.

Results

A total of 20 cohort studies consisting of 4 021 HCC patients were included.In the Meta-analysis of these 20 studies, 7 risk factors were finally screened after combined effects, including AFP (OR=1.38, 95%CI: 1.22-1.54), GGT (OR=1.49, 95%CI: 1.14-1.83)and ALB (OR=0.90, 95%CI: 0.78-1.02), intratumoral artery (OR=3.48, 95%CI: 3.12-3.85), peritumoral enhancement (OR=2.49, 95%CI: 1.94-3.04), tumor diameter (OR=2.93, 95%CI: 2.59-3.27) and extrahepatic growth (OR= 2.08, 95%CI: 1.75-2.42), respectively.7 risk factors were divided into the imaging feature group,laboratory index group and combined group, and assigned with values, and 3 models were constructed to predict early postoperative recurrence of HCC.The AUC of the model in the combined group was 0.877, and the sensitivity and specificity were 0.813 and 0.875, respectively.The prediction performance of this model was almost consistent with the actual values, indicating high clinical benefits.

Conclusions

Meta-analysis demonstrates that the risk factors of MVI in HCC include AFP, GGT, ALB, intratumoral artery, peritumoral enhancement, tumor diameter and extrahepatic growth.The prediction model for MVI risk based on Metaanalysis yields favorable prediction performance, which can be used as an assessment tool for the risk of MVI.
