KI-67 refers to the ability to describe the proliferation of a patient’s cancer cells, with a value of 80% indicating that the patient’s cancer cells are proliferating at a rapid rate.
KI-67 itself refers to a nuclear protein encoded by the MKI-67 gene, hence the name MKI-67, which indicates the degree of active cell proliferation. In the pathology reports of postoperative patients or post-puncture patients, the value of KI-67 is often recorded, ranging from 0 to 100%, with higher values indicating more active proliferation and faster growth of tumor cells.
Clinicians usually choose the most suitable treatment plan for the patient based on the results of the pathology report, in which KI-67 is an important assessment tool. The higher the KI-67 value, the more aggressive the treatment plan will be in favor of surgery or an increase in the type or dose of medication.
