Development and Validation of the Surgical Assessment and Healthcare (SAH) Index for Gastric Cancer Treatment Evaluation

This study develops the Surgical Assessment and Healthcare (SAH) Index, a new tool to fairly evaluate gastric cancer surgery outcomes. Gastric cancer is a serious disease that often requires major surgery, but it can be difficult to compare how well different hospitals or surgeons perform because patients have different levels of risk before surgery. The SAH Index will help solve this problem by creating a standardized way to account for patient risk factors when evaluating surgical results. The study analyzes data from 780 patients who had gastric cancer surgery in 2019, looking at factors like patient age, tumor characteristics, molecular markers, and surgical outcomes. By combining clinical information (like patient health), pathological details (like tumor type), and molecular features (like genetic markers), the SAH Index will create risk categories that allow fair comparison of surgical outcomes. This tool could help hospitals improve their care, help patients and families understand their treatment options, and help doctors make better treatment decisions. The study uses only existing medical records and does not involve any new treatments or procedures. The goal is to create a practical tool that can be used by hospitals and doctors to better evaluate and improve gastric cancer surgery outcomes.
