Metastatic Lymph Node Distribution in the Ileum Mesentery of Cecal and Proximal Ascending Colon Cancer

Based on the above considerations, our team maintains that it is currently imperative to conduct a prospective multicenter registry study. This study would involve sectioning and submitting fresh surgical specimens from the ileum mesentery of patients undergoing radical resection for cecal cancer and proximal ascending colon cancer (right-sided colon cancer). The objectives are to: Clarify the distribution range of metastatic lymph nodes within the ileum mesentery; Conduct survival follow-up on enrolled patients; Provide reliable evidence-based medical evidence for the individualized determination of ileal resection margins.
