BACKGROUND: Regional lymph node metastases are an important predictor of survival for patients with resectable adenocarcinoma of the stomach. Currently, the number of lymph nodes examined is frequently less than requirements for accurate staging. Clinical factors associated with lymph node recovery are understood poorly. METHODS: We performed a retrospective chart review of 99 consecutive patients who underwent gastrectomy for gastric adenocarcinoma distal to the gastroesophageal junction to determine clinical variables associated lymph node recovery. RESULTS: Ninety-nine patients underwent gastrectomy for gastric adenocarcinoma at our two hospitals. More than 15 lymph nodes were examined in 64% of specimens. Univariate analysis showed an association between the number of lymph nodes recovered and the number of positive nodes, lymphadenectomy extent, hospital, surgeon, and pathology technician (p < 0.001). Multivariate analysis identified the pathology technician as the most important healthcare-related variable contributing to the variation of lymph node recovery, using fixed- (p < 0.001) and random-effects models. CONCLUSIONS: This study suggests that the pathology technician is an important healthcare-related factor influencing lymph node recovery after gastrectomy. In identifying potential areas benefiting from a systems improvements approach, focus on the technical aspects of specimen processing may be of benefit in maximizing the number of lymph nodes recovered.
