Ki67
Use
Ki-67 is a nuclear protein associated with cellular proliferation. In pathology, Ki-67 is widely used to assess the proliferation rate of tumor cells, which can be an important indicator of tumor aggressiveness and prognosis. High Ki-67 expression is often correlated with more aggressive cancers, and its evaluation can guide treatment decisions, particularly in assessing the need for chemotherapy.
