Core Tip: Acknowledges the study's comprehensive analysis and its contribution to hepatocellular carcinoma management. These findings suggest further exploration of the clinical applicability of the neutrophil-lymphocyte ratio, fibrosis index based on four factors, and aspartate aminotransferase-to-platelet ratio index in diverse patient groups. Prospective studies for the validation of these findings are recommended. This highlights the importance of considering the confounding factors in future research.

TO THE EDITOR

We recently read the insightful study titled "Predictive value of NLR, Fib4, and APRI in the occurrence of liver failure after hepatectomy in patients with hepatocellular carcinoma" by Kuang et al[1], which was published in the World Journal of Gastrointestinal Surgery. The study's exploration of neutrophil-lymphocyte ratio (NLR), fibrosis index based on four factors (Fib4), and aspartate aminotransferase-to-platelet ratio index (APRI) as predictive markers for liver failure post-hepatectomy in hepatocellular carcinoma (HCC) patients is commendable.

The researchers' meticulous approach to developing and validating a column-line graph prediction model based on these markers is a significant advancement in predicting postoperative complications in HCC patients. The use of a large sample size and the division of patients into modeling and validation cohorts strengthens the study's validity. The high concordance between predicted and actual events in the study emphasizes the potential of these markers as tools for better clinical decision-making[2].

However, several aspects could be enhanced or explored further[3]. First, while the present study effectively established the predictive value of the NLR, Fib4 levels, and APRI, it primarily focused on a retrospective patient cohort. Prospective studies could further validate these findings and assess their applicability in real-time clinical settings.

Moreover, the study's focus on a single hospital's patient cohort may limit the generalizability of the findings. A multicenter study encompassing diverse demographic and genetic backgrounds could provide a more comprehensive understanding of the predictive value of these markers across different populations[4].

Additionally, the paper briefly touches upon the potential impact of confounding factors such as underlying liver diseases, other comorbidities, and different treatment regimens. A more detailed exploration of how these factors might influence the predictive accuracy of the NLR[5], Fib4, and APRI would be beneficial. Such an analysis could lead to a more nuanced understanding of the limitations and scope of these biomarkers in clinical practice.

Another aspect worth considering is the practicality of implementing these predictive models in clinical settings. While the study presents a robust statistical model, the translation of these findings into a simple, accessible format for routine clinical use would be a significant step forward. This could include the development of an easily interpretable scoring system or a digital tool that can be integrated into existing hospital information systems.

Finally, this study opens avenues for exploring the role of these biomarkers in the broader spectrum of liver diseases and surgeries[6]. Future research could focus on whether these markers can predict outcomes in other liver surgeries or liver-related conditions, potentially broadening the scope of their clinical utility.

In conclusion, the study by Kuang et al[1] is a valuable addition to the field of hepatology and surgical oncology. This study not only advances our understanding of postoperative complications in HCC patients but also sets the stage for further research that could ultimately enhance patient outcomes and personalized treatment approaches.
