Background and Objectives The aim of this study is to investigate predictive factors for unexpected peritoneal seeding from clinically resectable advanced gastric cancers to suggest the indications for staging laparoscopy (SL). Methods A total of consecutive 589 gastric cancer patients who were clinically diagnosed with advanced gastric cancer with no metastatic disease underwent operations at Seoul St. Mary's Hospital. Results A total of 72 patients (including 35 patients with seeding to distant peritoneum) were surgically diagnosed with peritoneal seeding. Borrmann type 3 (OR: 4.475) or type 4 (OR: 8.243) cancer, tumor invasion of T3 (OR: 2.794) or T4 (OR: 6.841) and tumor size (4 cm ≤ tumor size < 8 cm; OR: 3.723 and 8 cm ≤ tumor size; OR: 6.971) were predictive factors for overall peritoneal seeding. Borrmann type 3 (OR: 3.524) or 4 (OR: 4.695) cancer, tumor invasion of T3 (OR: 4.378) or T4 (OR: 15.817), and tumors involving the anterior wall (OR: 2.762) also turned out to be predictive factors for distant peritoneal seeding. Conclusions If SL were performed by these predictive factors, this should have been performed in 42.4% of advanced gastric cancers and the detection rates for overall peritoneal seeding would have been 24.0%.
