The Value of Peritoneal Cytology as a Preoperative Predictor in Patients With Gastric Carcinoma Undergoing a Curative Resection

Background Although positive peritoneal cytology is associated with poor prognosis, it has not been found to be independently predictive of outcome when evaluated in context of post-resection pathologic T and N stage. This study was undertaken to evaluate the predictive value of positive cytology in context of other prognostic factors available prior to surgery in patients undergoing R0 resection for gastric cancer, to assess its role in selecting patients for appropriate treatment prior to surgical resection.
