Site-Specific Factor 2

Vein Involvement

Notes

**Note 1:** Information about vein involvement is collected in T as an element in anatomic staging.  It is also collected in this field as it may have an independent effect on prognosis. **Note 2:** Record the involvement of specific named veins as documented in the pathology report. Do not code invasion of small unnamed vein(s) of the type collected as lymph-vascular invasion. Lymph-vascular invasion is usually only seen microscopically. * Assign code 000 if surgical resection of the primary site is performed, the pathology report is available for review, and involvement of these specified veins is not mentioned
