[Resection of XXXX infiltrating the left main bronchus following complete response to preoperative radiochemotherapy--a case report].

We report a case of @entity418 infiltrating the left main bronchus in which radical esophagectomy with clear surgical margins could be performed after preoperative radiochemotherapy. The @entity1 was a 57-year-old @entity1 , who was found to have @entity1721 of the middle thoracic esophagus during a work-up of @entity1282 . Bronchoscopy revealed an elevated region protruding into the lumen of the left main bronchus. After radiochemotherapy (liniac irradiation + low-dose FP therapy), the esophageal and @entity2488 became smaller. The case was evaluated as a clinically complete response. Bronchoscopic ultrasonography showed a clear boundary between the membranous portion of the @entity825 and the esophageal wall. Based on these findings, the lesion was considered resectable and radical surgery, including 3-field lymph node dissection, was performed. The resected esophageal specimen had @entity5 covered with normal mucosa. However, the @entity1 is currently healthy with no evidence of disease. The indication for surgical resection in cases of @entity418 with contiguous spread, and a good response to preoperative radiochemotherapy, is controversial. It is necessary to verify the effectiveness of surgical resection, as a secondary treatment, by accumulating data on cases such as the present one.
