Purpose: Adequate resection and evaluation of lymph nodes after colectomy is now used as a quality indicator and is associated with improved survival. The extent that patient factors, including ethnicity, influence the number of nodes harvested is still unknown. The aim of this study is to determine the association between ethnicity and lymph node retrieval after colon cancer resection.Methods: This study is a historic cohort using the Surveillance and End Results (SEER) - Medicare database. A total of 32,936 patients were identified who underwent colon cancer resection from 2000-2003. The study period ended in 2003, when the number of lymph nodes was no longer recorded as a data point. Statistical analysis was performed using SAS software (Version 9.3). Since 12 lymph nodes constitutes an adequate number for accurate staging, subjects were classified as having <12 (N=20,605) or ≥12 (N=12,358) examined. Next, univariate and multivariate logistic regression models were used to analyze the relationship between lymph nodes resected and independent variables. Independent variables included were ethnicity, age, gender, cancer stage, income, and comorbidities. Results:
