Rectal cancer surgery and regional lymph nodes

This is the authors' abstract. We don't add key points for this paper.

In patients with rectal cancer, the status of regional or mesorectal lymph nodes is central to both tumor staging and predicting local and distant recurrence. The importance of mesorectal lymph nodes in rectal cancer should inform treatment decisions around pre-operative diagnostic imaging, surgical techniques, pathologic assessment, and the use of radiation therapy.
