Gastroesophageal reflux (GR) after radical resection of proximal gastric cancer (PGC) may influence survival; however, few studies have investigated survival in PGC patients who develop GR following radical resection. This study aimed to correlate the occurrence of GR after proximal gastrectomy (PG) and total gastrectomy (TG) with clinicopathological factors and long-term survival.


The PGC patient cohort was retrospectively grouped as follows: postoperative patients with and without GR (NGR). Clinicopathological characteristics and survival data were compared between the two groups.


A total of 88 patients who underwent PG (53%) experienced postoperative GR; however, only 30 patients who underwent TG (14%) experienced GR (P = 0.000). The incidence of GR was significantly associated with surgical procedure (P < 0.01), tumor size (P < 0.01), infiltration depth (P < 0.01), lymph node metastasis (P = 0.018), postoperative distant metastasis (P < 0.01) and recurrence (P = 0.001). The 5-year overall survival of the GR group was significantly worse than that of the NGR group (39.3 vs. 46.5%, respectively; P = 0.046). The PG and TG groups had significantly different 5-year overall survival (45.2 vs. 50.9%, respectively; P = 0.047), and multivariate analysis revealed GR as an independent risk factor associated with poor overall survival.


Patients who experienced GR after radical resection for PGC were more likely to develop recurrence and metastasis, leading to shorter survival. TG for PGC was associated with a more favorable 5-year overall survival than was PG. Thus, TG should be performed for PGC patients with tumors larger than 5 cm, T3/T4 disease or lymph node metastasis to improve their long-term survival.
