Comments

Guide for use:

Record each immunohistochemical profile obtained to assist in the diagnosis of cancer.

When "other" is recorded, record the immunohistochemistry stain in text in Person with cancer—immunohistochemistry type, text X[49].

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

Comments:
Immunohistochemistry may be helpful in some instances for precise histological subclassification of the tumour and the exclusion of metastasis.
