Evolving treatment strategies for resectable gastric cancer: Bridging Asia-West disparities toward personalized and integrated therapy.

Gastric cancer (GC) remains a significant global health burden. Both Asian countries and Western nations, represented by Europe and North America, have long been pioneers in GC research and continue to lead advancements in the field. However, notable differences have historically existed between these regions in the treatment of resectable GC. In recent years, increasing convergence between Asian and Western approaches has emerged, driven by the growth of global collaborative studies. New definitive evidence suggests that the therapeutic landscape for resectable GC may undergo a significant transformation. In this review, we comprehensively examine the evolution of surgical approaches and perioperative chemotherapy strategies in Asia and the West. We summarize key clinical trials, highlight persistent survival disparities, and provide insight into current trends in perioperative management, including the recent advances in molecularly driven perioperative treatments. Finally, we outline key considerations for future multicenter perioperative trials to further guide global clinical practice.
