In this study, we aimed to develop a predictive model of lymph node yield in a series of colon cancer resection specimens with detailed anatomic and surgical technique data.
Lymph node yield in colon resection specimens has been associated with the accuracy of staging and cancer outcomes. It has been proposed that the more central the mesenteric vascular ligation, the greater the nodal yield. However, the optimal number of harvested nodes is still a matter of debate. We prospectively evaluated the relation between specimen properties such as lenght, area, tumor location and pedicle length to the number of harvested nodes and rate of node positivity.
