Despite the significant recent achievements in the diagnosis and treatment of these patients, the number of deaths for these tumors has currently plateaued. Many investigations have assessed the role of HER2 in tumors of the digestive system in both prognostic and therapeutic settings, with heterogeneous results. Novel testing and treatment guidelines are emerging, in particular in gastric and colorectal cancers. However, further advances are needed. In this review we provide a comprehensive overview of the current state-ofknowledge of HER2 alterations in the most common tumors of the digestive system and discuss the operational implications of HER2 testing.展开更多

Meth-ods: From April 1979 to October 1998, Thirty-one patients with benign esophageal stenosis and 15 patients with esophagus carcinoma received the colonic interposition for esophageal reconstruction. There were 5 pa-tients with the esophagus carcinoma after subtotal gastrectomy. Four of 5 cases received colonic interposition graft from the esophageal bed after the esophagus was pulled out without thoracotomy. Results: There was no perioperative death. All 31 cases of the benign esophageal stenosis got long term survival and normal life. The 3- and 5-year survival rates of patients with the carcinoma of the esophagus were 63. 6% and 40. 6% re-spectively. Conclusion: The colonic interposition graft is a choice for the patients with the cervical stenosis of the esophagus, especially for those already had subtotal gastrectomy. Using the left colonic artery as the sup-porting vessel and using the colon segment in an isoperistaltic position is the optimal choice. Improving the operative techniques and decreasing the complications are important for the extension use of this method.展开更多
