摘要: Background The American Joint Committee on Cancer staging of esophageal cancer has been criticized for not establishing a minimum standard lymphadenectomy, and relying location nodes involved rather than their number. objective this study was to review the current practice surgeons with regard lymph node assessment during resection. Methods operative pathology reports patients who underwent by computed tomography fluorodeoxyglucose-positron emission subsequent resection (multiinstitutional College Surgeons Oncology Group Z0060 trial) were analyzed. Results One hundred forty-five Operative unavailable in 11 patients. results remaining 134 resections (Ivor-Lewis, n=64; transhiatal, n=59; other, n=11) reviewed. Overall, 13 ± 9 (mean deviation) evaluated per patient.
