Core Tip

Core Tip: This multicenter retrospective study compares proximal gastrectomy (PG) with tubular stomach reconstruction vs total gastrectomy (TG) for proximal gastric cancer following neoadjuvant chemotherapy. Our analysis of 244 propensity score-matched patients reveals that PG achieves comparable survival outcomes and surgical safety to TG, while offering significant advantages in operation time and postoperative reflux prevention. These findings support PG with tubular stomach reconstruction as a viable alternative to TG, potentially improving quality of life without compromising oncological efficacy in this patient population.
