Lymphovascular invasion, also lymphovascular space invasion, is (non-hematologic) malignant cells within blood vessels and/or lymphatics. It is abbreviated LVI.
The term lymphovascular invasion is preferred to vascular invasion, as it is very difficult to differentiate morphologically small lymphatics and small vascular spaces, without immunohistochemistry.
General
- LVI, in the TNM staging system, does not affect tumour stage; however, there are exceptions.
- Exceptions:
- Seminoma.
- Squamous cell carcinoma of the penis.
- Intrahepatic bile duct carcinoma (cholangiocarcinoma).[1]
- Hepatocellular carcinoma.[2]
- Exceptions:
- Absence of LVI in the context of proven lymph node metastasis = sampling error.[3]
- The prognostic significance of LVI, generally, is dependent on the tumour type and may depend on the tumour stage and lymph node status.
- Most generally -- LVI = poorer prognosis.[4]
Specific tumours and LVI
| Tumour | Prognosis | Comment |
|---|---|---|
| Urothelial carcinoma | independent predictor of a poor prognosis in bladder tumours | LVI has more predictive power than tumour stage in the urinary bladder;[5] appears to be less important in upper urinary tract disease[6] |
| Breast cancer | not an independent predictor[7] | |
| Colorectal carcinoma | independent predictor of poorer prognosis (sporadic cancers)[8] | may be used as a quality measure; 25% of cases should have vascular invasion[9] |
Microscopic
Rosen criteria for LVI (in the breast):[10][11]
- Must be outside of the tumour proper.
- LVI is usually very close -- typically within 0.1 cm.
- Contour of cells should differ from possible vessel wall.
- DCIS with retraction artifact mimicing LVI has a contour that matches its surrounding fibrous tissue.
- Endothelium (usu. flat) should be visible.
- Lymphatics are found adjacent to blood vessels - vessels should be present in the vicinity.
Memory device LUBE-O:
- LVI has a Unique contour, Blood vessels and Endothelium in the vicinity, and is Outside of the tumour.
Notes:
- Criteria for LVI vary by the site/tumour.
- In some sites, the first criterium (tumour cells outside of the tumour proper) isn't required.

- Movat stain - especially useful in colorectal carcinoma so one can readily identify blood vessels.[12]
- Elastin stain.
