Annex 3.
l When determining if adjuvant therapy should be administered for stage II, the following should be taken into consideration:
- Number of lymph nodes analyzed after surgery (<12)
- Poor prognostic features (eg, poorly differentiated histology [exclusive of those that are MSI-H]; lymphatic/vascular invasion; bowel obstruction; PNI; localized perforation; close, indeterminate, or positive margins; or high tumor budding)

Annex 4. Recommendations from the IDEA study for adjuvant treatment of colon cancer (32).

Other additional clinicopathological features such as the histological subtype and grading, lymphatic or venous or perineural invasion, lymphoid inflammatory response, involvement of resection margins and < 12 lymph nodes examined should be taken into consideration for refining the risk assessment on stage II tumours. |
