Background/Aims: The presence of metastases in lymph nodes is an important prognostic factor in patients with gastric cancer. Currently, the total number of metastatic lymph nodes (MLN) is thought to be more prognostically significant than the anatomical distribution of MLN. Methodology: The associations of the total number of MLN and of the number of perigastric (PG) MLN with long-term survival were retrospectively evaluated using uni- and multivariate analysis in 481 node-positive gastric cancer patients who underwent potentially curative resections. Results: The number of PG MLN was a better prognostic indicator than the total number of MLN (indices of correlation 0.2908 and 0.3424, respectively). Good surgical results were obtained in patients with 5 PG MLN or fewer. Conclusions: The number of perigastric metastatic lymph nodes is a more conveniently obtained and reliable prognostic factor than the total number of metastatic lymph nodes in patients with node-positive gastric cancer.
