Concordance of clinical diagnosis of T classification among physicians for locally advanced unresectable thoracic esophageal cancer

Background We conducted a multicenter phase II trial assessing chemoselection with docetaxel plus 5-fluorouracil and cisplatin induction chemotherapy and subsequent conversion surgery for locally advanced, unresectable esophageal cancer. The aim of this study was to validate the concordance of clinical T diagnosis among physicians in the cases of this trial.
