Abstract

Advances in gastric cancer screening have enabled earlier detection, shifting the focus of treatment toward preserving patients’ quality of life (QoL). Function-preserving gastrectomy (FPG), including pylorus-preserving gastrectomy, proximal gastrectomy, and sentinel node navigation surgery, represents a paradigm shift in the surgical management of early gastric cancer. These techniques aim to balance oncological safety with the preservation of gastric function, mitigating postgastrectomy syndromes such as dumping syndrome, bile reflux, and nutritional deficiencies. QoL assessment tools, including EORTC QLQ-STO22, KOQUSS-40, and PGSAS-45, have become integral for evaluating patient-reported outcomes, providing insights into physical, emotional, and functional recovery. Although current evidence underscores the benefits of FPG, most studies are limited to East Asia, highlighting the need for multinational trials to validate these findings globally. FPG has demonstrated comparable short- and long-term oncological outcomes to conventional gastrectomy. Enhanced nutritional recovery and reduced gastrointestinal sequelae make FPG increasingly attractive. However, its widespread adoption is challenged by technical complexity, resource intensity, and the need for adequate surgical experience. The integration of advanced technologies, such as robotic surgery and artificial intelligence, coupled with personalized approaches, is expected to further optimize FPG outcomes. This review underscores the critical role of standardized QoL assessments, collaborative research, and technological innovations in advancing FPG as a cornerstone of patient-centered gastric cancer care.
