Aim: Dissection of ≥12 lymph nodes is recommended for curative surgery of colon neoplasms. The aim was to determine the clinicopathological factors associated with poor lymph node dissection. Method: Patient hospital records in those undergoing surgery due to stage 1-3 colon neoplasm, between January 2009 and December 2017, were retrospectively evaluated. Univariate and multivariate analyses were performed to evaluate the clinical and pathological risk factors associated with poor lymph node dissection. Results: The patient population during the study period numbered 388. Of these, <12 lymph nodes were dissected in 21.9%. Tumor location in the left colon, large tumors, deep penetrating tumors and short surgical margins were found to be independent risk factors for poor lymph node dissection by univariate analysis. Male gender, left colon location, large-sized tumors and deep penetrating tumors were confirmed as being independent markers for poor lymph node dissection by multivariate analysis. Conclusion: Adequate lymph node dissection for colon neoplasm patients has prognostic significance. Male patients, advanced pT stage neoplasm, and left colon tumors had an increased risk of poor lymph node dissection. Therefore, lymph node dissection should be undertaken particularly meticulously in these patients.
