Background:  The optimal extent of gastrectomy and lymphadenectomy for esophagogastric junction (EGJ) cancer is controversial. Our study aimed to compare the long-term survival of transhiatal proximal gastrectomy with extended periproximal lymphadenectomy (THPG with EPL) and transhiatal total gastrectomy with complete perigastric lymphadenectomy (THTG with CPL) for patients with the stomach-predominant EGJ cancer.   Methods:  Between January 2004, and August 2015, 306 patients with Siewert II tumors were divided into the THTG group ( n  = 148) and the THPG group ( n  = 158). Their long-term survival was compared according to Nishi's classification. The Kaplan–Meier method and Cox proportional hazards models were used for survival analysis.   Results:  There were no significant differences between the two groups in the distribution of age, gender, tumor size or Nishi's type ( P  > 0.05). However, a significant difference was observed in terms of pathological tumor stage ( P  < 0.05). The 5-year overall survival rates were 62.0% in the THPG group and 59.5% in the THTG group. The hazard ratio for death was 0.455 (95% CI, 0.337 to 0.613; log-rank  P  < 0.001). Type GE/E = G showed a worse prognosis compared with Type G ( P  < 0.05). Subgroup analysis stratified by Nishi's classification, Stage IA-IIB and IIIA, and tumor size ≤ 30 mm indicated significant survival advantages for the THPG group ( P  < 0.05). However, this analysis failed to show a survival benefit in Stage IIIB ( P  > 0.05).   Conclusions:  Nishi's classification is an effective method to clarify the subdivision of Siewert II tumors with a diameter ≤ 40 mm above or below the EGJ. THPG with EPL is an optimal procedure for the patients with the stomach-predominant EGJ tumors ≤30 mm in diameter and in Stage IA-IIIA. For more advanced and larger EGJ tumors, further studies are required to confirm the necessity of THTG with CPL.
