Insufficient lymph node assessment in gastric adenocarcinoma

Background This study aimed to investigate the sufficient (≥ 16) lymph node assessment in 449 patients with gastric adenocarcinoma and literature review. Methods Four hundred and forty-nine patients with pathologically confirmed locoregional invasive gastric adenocarcinoma from 2004 to 2013 were included. A standard surgical resection was performed for all the patients with ( n = 16) or without ( n = 433) neoadjuvant treatment. Results In this study, 301 men and 148 women with a median age of 58 (range 21–88) years were included. The median total numbers of examined lymph nodes were 9 (range 0–55). Ninety-five patients (21.2%) had adequate (≥ 16) lymph node examination, and 70 patients (15.6%) had no examined lymph nodes. In univariate analysis, total or near total gastrectomy ( P
