Ki-67 is an index that reflects the proliferation of cancer cells, because every breast cancer patient’s cancer cells are not exactly the same, and all Ki-67 does not have a fixed range.
Ki-67 is a protein encoded by the MKi-67 gene, also called MKi-67.
After pathology-free examination of puncture specimens as well as surgical gross pathology specimens from breast cancer patients, the pathology report will suggest the patient’s Ki-67 value to indicate the degree of active cell proliferation. Meanwhile, the level of Ki-67 is closely related to the degree of differentiation, infiltration, metastasis and prognosis of cancer cells.
Therefore, breast doctors usually adjust the medication regimen according to the Ki-67 value in the patient’s pathology report.
