title: Clinical outcome of esophageal cancer patients with history of gastrectomy.
abstract: BACKGROUND
  Surgery for thoracic esophageal cancer after gastrectomy involves a complicated reconstruction procedure. A surgeon's hesitation is further increased because the clinical outcome of surgical treatment of these patients has not been elucidated.
  
  
  OBJECTIVE
  Among 948 thoracic esophageal cancer patients who underwent curative operation, 72 (7.6%) had a history of gastrectomy. Their clinico-pathological features and survival (follow-up average 881 days) were compared with those without gastrectomy.
  
  
  RESULTS
  Esophagectomy for patients after gastrectomy was performed via right thoracotomy (66), left thoracotomy (4), and transhiatal resection (2), and reconstruction was done using the right-side colon (57) or jejunum (15). Compared to non-gastrectomized patients, gastrectomized patients were exposed to longer operation time (523 min vs. 460 min), but no significant difference was observed in operative mortality (4.2% vs. 2.5%) or blood loss (1,189 ml vs. 990 ml). Pathological examination showed no significant difference in depth of tumor invasion, lymph node metastasis, and TNM staging between gastrectomized and non-gastrectomized patients, while tumors were located at lower position in the gastrectomized patients (P = 0.046). The overall and cause-specific 5-year survival rates were 56% and 65% for gastrectomized esophageal cancer patients, which were significantly better than for non-gastrectomized patients (36% and 44%, P = 0.0235 and 0.024, respectively). Multivariate analysis showed gastrectomy as a marginally independent factor for a favorable prognosis (hazard ratio 1.832, P = 0.0324). With respect to tumor recurrence, hematogenic metastasis tended to be less frequent in gastrectomized patients than in non-gastrectomized patients. In gastrectomized patients, neither disease (peptic ulcer or gastric cancer) nor reconstruction (Billroth-I, Billroth-II, and Roux-Y) for gastrectomy affected the clinicopathological findings or post-operable survival.
  
  
  CONCLUSIONS
  Surgical treatment of esophageal cancer patients after gastrectomy was complicated but tolerable, and should be considered as a reliable therapeutic modality because of favorable patient prognosis.
