Abstract: Objective To investigate the clinical efficacy of resection for Thoracic Gastric Cancer（TGC）after esophagectomy.
Methods Between June 2013 and December 2018，7 individuals with gastric cancer in the reconstructed gastric tube after esophagectomy in Renmin Hospital of Wuhan University were studied.
Results A total of 7 patients with TGCs were selected for this study.There were 6 male patients，the average age at diagnosis was 63.2 years（range：53～73）and that the interval between esophagectomy and cancer onset in the reconstructed gastric tube ranged from 2.8 to 15 years.There were no operative or in-hospital mortalities.The operative time ranged from 170min to 580min and the blood loss ranged from 350 to 1100ml.Postoperative pulmonary infection occurred in 2 cases and arrhythmia in 1 case.Neck anastomotic fistula occurred in 1 case，which was cured two weeks after dressing change through incision.The postoperative follow-up was made for 12 months in the whole patients and all of them were alive with eating normally.
Conclusion The development of TGC should be taken into consideration during the extended follow-up of patients undergoing esophagectomy for cancer.Gastrectomy should be considered the preferred treatment modality in operable patients with locally invasive tumor.
