Abstract Objectives To investigate the clinicopathological characteristics and surgicl outcome of thoracic esophageal cancer after gastrectomy, and compare with those without gastrectomy. Result Among 1411 esophageal cancer patients who underwent curative operation, 48 (3.4%) had a history of distal gastrectomy, the interval between gastrectomy and esophagectomy was significantly shorter in those gastrectomized for gastric cancer (11.5 ± 8.2 years) than for peptic ulcer (24.6 ± 9.2 years), the proportion of lower-third tumors and multiple esophageal cancer was significantly higher compared with that of the non-gastrectomized patients (50.0% vs. 33.1%, P = 0.033; 14.6% vs. 5.3%, P = 0.006, respectively), this increase was more pronounced after Billroth I vs. Billroth II gastrectomy. Pathologically, the esophageal cancers after gastrectomy frequently showed expansive growth pattern (39.6%), while those without gastrectomy dominantly showed infiltrative growth pattern (40.3%) ( P = 0.012), the coexisting lesions showed well-differentiated squamous cell carcinoma confined within the superficial mucosal layer. Compared with the non-gastrectomized patients, the operative time (311.2 ± 86.0 vs. 263.7 ± 84.9 min; P < 0.001) was longer and blood loss (4.38 ± 1.33 vs. 3.57 ± 1.82 IU; P = 0.003) was more, the postoperative hospital stay was significantly longer in gastrectomized patients (median 69 days vs. 40 days, P < 0.001). The overall 1, 3, 5, 10-year survival of gastrectomized and non-gastrectomized patients were similar, and their cause-specific 5-year survival were 65% vs. 44% ( P = 0.992). Conclusions Gastrectomy (especially the Billroth I) precipitated subsequent chronic gastroesophageal reflux and induced the development of squamous dysplasia and carcinoma at multiple locations in the esophagus. Surgical treatment of the gastrectomized patients should be considered as a reliable therapeutic modality because of favorable prognoses.
