Prognostic role of positive peritoneal cytology in patients with resectable gastric cancer.

Objective: To evaluate the prognostic value of positive peritoneal lavage in patients with gastric cancer without signs of peritoneal or hematogenous spread.

Methods: We evaluated patients with gastric adenocarcinoma treated with curative intent operation. The peritoneal lavage was classified as positive or negative for neoplastic cells.

Initial experience in Brazil with endoscopic submucosal dissection for early gastric cancer using insulation-tipped knife: a safety and feasibility study.

Background: Endoscopic resection is an adequate treatment for subgroups of patients with early gastric cancer. Endoscopic submucosal dissection (ESD) represents a recent advance and leads to good results when adequately indicated. There is great experience with this technique in Japan and it is gaining acceptance among Western endoscopists.
