How is ki67 measured
WebBreast cancers expressing high levels of Ki67, a nuclear marker of cell proliferation, are associated with worse outcomes ( 10 – 12 ). Ki67 is not included in routine clinical decision-making because of a lack of clarity regarding how Ki67 measurements should infl u-ence clinical decisions.

How is ki67 measured
Did you know?
WebKi-67 (or Ki67) is used as a measure of the proliferative activity of breast cancer cells. Ki-67 is an antigen, a substance that causes the immune system to produce antibodies against it. It is a protein found only in growing, dividing cells (and not in cells in the resting phase of the cell growth cycle). See also Ki-67-based recurrence data.
Web2 dagen geleden · Ki67 was measured centrally in core-cut biopsies taken prior to AI and in core-cuts or the excision biopsy at surgery. Relationships between the Ki67 and biologic factors were explored using linear regression. Results: Established associations of Ki67 baseline with biologic factors including PgR status, tumour ...
