Core Tip

Core Tip: The triglyceride-glucose (TyG) index, a surrogate marker for insulin resistance, has emerged as a potential prognostic factor in advanced gastric cancer. Recent findings suggest that a high TyG index correlates with improved overall survival and progression-free survival in patients undergoing immunotherapy combined with chemotherapy. This highlights the clinical relevance of insulin sensitivity in modulating treatment efficacy. Further multicenter studies are essential to validate its prognostic value across diverse populations and to explore underlying mechanisms. Integrating the TyG index into comprehensive prognostic models may optimize treatment strategies and improve patient outcomes in advanced gastric cancer.
