ARTICLE HIGHLIGHTS
Research background

No preoperative prognostic models specific to hepatocellular carcinoma patients receiving surgical resection have been considered strong and convincing enough for survival prediction.

Research motivation

We previously derived a nomogram but aimed to simplify the score and compare it with other scoring systems.

Research objectives

To develop a simple preoperative score with satisfactory predictive power compared to postoperative scoring systems.

Research methods

Significant risk factors were identified using a multivariate Cox proportional hazards model. The homogeneity, Harrell’s C-index, and Akaike information criterion of the different scoring systems were compared.

Research results

Five risk factors were identified, and patients were divided into three risk groups. The C-index of our preoperative score was 0.617, which is equal to the value of the AJCC 8th edition.

Research conclusions

A modified score was established for survival prediction, and patients were divided into risk groups for preoperative treatment planning.

Research perspectives

Specific treatment or monitoring plan modifications for each risk group should be studied and potential correlation with survival benefit should be investigated.
