tumoral infiltration of the mesorectum

The 1-cm distal margin recommended in patients with low rectal carcinoma could be reduced with insurance to obtain a negative distal margin.

The knowledge of preferential localization of mesorectal metastatic lymph nodes (MLNs) and mesorectal extranodal cancer tissue (EX) would help the pathologist to improve patient’s lymph node staging.
