California Cancer Reporting System Standards Volume I: Abstracting and Coding Procedures for Hospitals
Lymph-Vascular invasion identifies the presence or absence of tumor cells within blood vessels, lymphatic channels (not lymph nodes) or surrounding tissue within the primary tumor as noted microscopically by the pathologist. Lymph-vascular invasion is an indicator of prognosis.
Lymph Vascular Invasion is required by the CCR to be coded for primary sites penis (C60.0; C60.8-C609.) and testis (C62.0-C62.1) for cases diagnosed 1/1/2010 and forward. For all other sites, if the pathologist provides information on lymph vascular invasion, it may be coded.
The primary source of this information is the College of American Pathologists (CAP) synoptic report or checklist. If the CAP is not available, code this data item from the pathology report or a physician’s statement within the medical record, in that order of priority.
This field is to be left blank for cases diagnosed before 2010.
For specific coding instructions see the Collaborative Staging Manual, Part 1, Section 1.
