ARTICLE HIGHLIGHTS
Research background

Liver cancer is one of the most common malignant tumors in China and is associated with high morbidity and mortality rates, which seriously threaten the health and life of Chinese residents. The prognosis following conventional hepatectomy is not ideal, with a recurrence rate of up to 70%.

Research motivation

The purpose of this study was to analyze the correlation between preoperative serum oxidative stress level and serum uric acid (UA), and prognosis in patients with hepatitis B-related liver cancer. This relationship was determined to identify simple and effective evaluation indicators for the assessment of disease condition and prognosis, and to provide data support for clinical improvement of treatment.

Research objectives

To explore the correlation between serum oxidative stress level and serum UA, and prognosis before hepatitis B-related liver cancer recurrence. It was found that serum oxidative stress level and serum UA before hepatitis B-related liver cancer were closely related to prognosis, which is helpful for clinicians to more effectively evaluate prognosis, recurrence and to guide treatment decision-making.

Research methods

The analysis methods used in this study involved a logistic regression model, Pearson analysis, Spearman analysis, and a receiver operating characteristic (ROC) curve, and the analysis target was the correlation between serum oxidative stress level, serum UA, and recurrence of hepatitis B-related liver cancer. The analysis of different research data layer by layer was rigorous and scientific.

Research results

This study found that superoxide dismutase (SOD), glutathione (GSH), malondialdehyde (MDA), and UA were all risk factors for postoperative recurrence in patients with hepatitis B-related liver cancer. Serum UA was positively correlated with MDA and negatively correlated with GSH. MDA and UA can predict the prognosis of patients with hepatitis B-related liver cancer. However, we could not determine the specific mechanism of the effect of these four indicators on postoperative recurrence in patients with hepatitis B-related liver cancer.

Research conclusions

This study found that SOD, GSH, MDA, and UA were all risk factors for postoperative recurrence in patients with hepatitis B-related liver cancer. Furthermore, ROC curve analysis showed that only MDA and UA predicted an AUC above 0.5, which was different to previous studies.

Research perspectives

Future research should include a larger sample and prospectively focus on the specific mechanism of oxidative stress level and UA level on the prognosis of hepatitis B-related liver cancer.
