Core Tip

Core Tip: This study introduces a novel inflammatory nutritional prognostic index (INPI) for advanced gastric cancer (AGC) patients undergoing gastrectomy and prophylactic hyperthermic intraperitoneal chemotherapy. Analyzing data from 181 patients, we established the INPI to stratify patients into three distinct risk groups, revealing significant prognostic differences. Our prognostic nomogram, integrating INPI with clinical features, demonstrated superior predictive performance compared to traditional tumor-node-metastasis staging, offering a valuable tool for personalizing treatment strategies and improving patient outcomes in AGC management.
