Tumour budding refers to lone tumour cells or small clusters of tumour cells at the advancing front of a tumour.[1]
General
- Poor prognosticator in colorectal carcinoma,[2] and invasive ductal carcinoma of the breast.[3]
Microscopic
Definition - rectal carcinoma:[4]
- Tumour bud = 1-4 cell(s) -- at the tumour front.
Grading:
- Low grade: 0-4 tumour buds.
- Intermediate grade: 5-9 tumour buds.
- High grade: >=10 tumour buds.
Note:
- Assessed in a field area of 0.785 mm2.[4]
- Tumour budding was previously assessed in a field of 0.385 mm2.[1]
DDx:
- Poorly differentiated adenocarcinoma.
