Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Colorectal cancers (CRC) extending beyond the muscularis mucosae and invading the submucosa without extending beyond it are classified as pT1.

Among these, a number of lesions presenting pejorative criteria, notably histopathological, have a significant risk of lymph node invasion, and are therefore candidates for partial colectomy with lymph node dissection. Tumors deemed to be at low risk of lymph node involvement can be treated by endoscopy alone.

It should be noted that further surgical intervention is not without comorbid consequences, and that a significant proportion of post-surgical surgical specimens are free of cancerous lesions.

The aim of this study is therefore to analyze the current histopathological criteria predictive of lymph node invasion, in order to more accurately select candidates for surgical management.
