ARTICLE HIGHLIGHTS
Research background

Gastric cancer is a serious public health issue, and the occurrence of serious complications and recurrence and metastasis after surgery remain difficult problems for clinicians. Patient survival rates are still low and the incidence of major postoperative complications cannot be disregarded. The systemic inflammatory response, nutritional level, and coagulation status are key factors affecting postoperative recovery and prognosis of gastric cancer patients. The systemic inflammatory response index (SIRI) and the albumin fibrinogen ratio (AFR) are two valuable comprehensive indicators of the severity and prognosis of systemic inflammation in various medical conditions.

Research motivation

The aim of this study was to assess the clinical importance and prognostic significance of the SIRI scores and AFR on early postoperative outcomes in patients undergoing radical gastric cancer surgery. These results may aid surgeons and oncologists in conducting more effective preoperative evaluations and management and developing postoperative monitoring plans for gastric cancer patients.

Research objectives

The objective of this study is to assess the clinical importance and prognostic significance of the SIRI scores and the AFR on early postoperative outcomes in patients undergoing radical gastric cancer surgery.

Research methods

We conducted an analysis of the clinicopathological characteristics and relevant laboratory indices of 568 gastric cancer patients from January 2018 to December 2019. We calculated and compared two indicators of inflammation and then examined the diagnostic ability of combined SIRI and AFR values for early postoperative serious complications. We scored the patients and categorized them into three groups based on their SIRI and AFR levels.

Research results

SIRI-AFR scores had the highest diagnostic power for early serious complications and were an independent risk factor for prognosis in gastric cancer patients. Furthermore, the tumor-node-metastasis stage, perioperative transfusion, positive carcinoembryonic antigen findings, and major postoperative complications were factors associated with prognosis. The significant value of the SIRI and AFR for the early severe postoperative complications and prognosis in gastric cancer patients can provide important insights for the future prevention and treatment of patients. However, we lacked an evaluation of postoperative SIRI and AFR dynamic changes in a relatively large cohort of gastric cancer patients. Therefore, larger multicenter prospective randomized controlled trials are needed to verify our conclusions. Even though SIRI and AFR values are worthwhile and easily attainable routine blood parameters, the underlying biological and molecular mechanisms that account for their prognostic and predictive nature remain unclear.

Research conclusions

In this study, we created novel markers and evaluated their diagnostic and predictive potential to aid in the early identification and treatment of gastric cancer.

Research perspectives

Larger multicenter prospective randomized controlled trials are needed to verify our conclusions. Additionally, the underlying biological and molecular mechanisms that account for the prognostic and predictive nature of SIRI and AFR values remain unclear. Further research is needed to elucidate the specific pathways and interactions through which these indicators impact the postoperative outcomes in gastric cancer patients.
