• Abstract:

  Gastric duct reconstruction after resection of esophageal carcinoma may develop a heterochronous tumor called gastric duct carcinoma. The purpose of this study was to use the Biomedical Information Retrieval System of the National Medical Library of the United States, the Netherlands Medical Abstracts, the Central Controlled Trial Registry of Scopus and Cochrane Libraries to conduct a comprehensive and systematic literature retrieval to review the literature resources, and evaluate the prognosis and possible treatment strategies of gastric cancer. This article did not set restrictions on the type of literature published, the number of patients, age or gender, but searched the literature and analyzed the characteristics of esophageal cancer and its treatment, and gastric tube cancer and its treatment. A total of 56 research cases were analyzed, including 24 cases of retrospective analysis and 32 cases of case report, involving 500 cases of gastric tube cancer. Squamous cell carcinoma was the most common type of esophageal carcinoma (87.2%); 267 cases (53.4%) underwent esophagectomy with posterior mediastinal reconstruction; The average interval between esophagectomy and gastric tube cancer diagnosis was 56.5 months, and the median interval was 57.5 months (4-234 months). 130 cases of gastric tube carcinoma (49.6%) were located in the lower part of the gastric tube, 134 patients received endoscopic treatment; 83 patients underwent surgery. 33 patients underwent total gastrectomy with colon or jejunum interposition, 42 patients underwent subtotal gastrectomy, and 8 patients underwent wedge resection. Postoperative complications were mainly anastomotic fistula, vocal cord paralysis, and respiratory failure; 27 patients received palliative chemotherapy. 3-year survival rate: 67.3% in endoscopic therapy group, 60.8% in surgical resection group, and 4% in palliative therapy group. The feasibility of endoscopic resection of superficial gastric tube carcinoma was reported. Surgical treatment is the first choice for patients with locally invasive tumors. The prognosis of patients treated conservatively was poor. The development of gastric tube cancer should be considered in long-term follow-up of patients after resection of esophageal cancer. Total gastrectomy plus lymphadenectomy is the first choice for surgical resection of local invasive tumors, while endoscopy is contraindicated, and long-term endoscopic follow-up is recommended every year.
