Abstract:
BACKGROUND:The purpose of the current study was to test the hypothesis that a lower clinical TNM stage is associated with a higher rate of pathologic complete response (pathCR) in patients with esophageal carcinoma receiving preoperative chemoradiotherapy and to determine whether outcome after pathCR is related to clinical stage or treatment.
METHODS:Clinical parameters and surgical specimens of patients with esophageal carcinoma undergoing preoperative chemoradiotherapy were analyzed to identify predictors of pathCR. In patients with pathCR, predictors of overall survival (OS), disease-free survival (DFS), and distant recurrence were studied.
RESULTS:Sixty-nine (29%) of 235 patients achieved pathCR. In patients with American Joint Committee on Cancer (AJCC) Stage II carcinoma, the proportion achieving pathCR was significantly larger than that achieving journal_name journal_title authors doi subject pub_date pages issue eissn issn journal_volume pub_type
