Comments

Guide for use:

Lymphovascular invasion refers to the invasion of cancer cells into the blood vessels or lymphatic channels.

Only record lymphovascular invasion described in the primary tumour, not for metastatic or recurrent disease.

If lymphovascular invasion is present, record whether an artery, vein or lymphatic channel is involved.

If more than one type of vessel is involved, record each appropriate code separately.

Context:
This should be collected for people with cancer where pathology data is available.

Comments:
Lymphovascular invasion may be an important prognostic factor indicating the tumour is likely to spread, and may influence treatment decisions.
