Collection and usage attributes

Guide for use:

Perineural invasion refers to cancer cells tracking along or around a nerve within the space surrounding a nerve. Its presence may be indicative of perineural spread, which can make the resection of malignant lesions more difficult.

Only record perineural invasion in the primary tumour, not for metastatic or recurrent disease.
Collection methods:This information should be sought from the patient's pathology report under microscopic findings.
Comments:The presence of perineural invasion may be an important prognostic factor for some cancers.
