After effective chemotherapy in patients, Ki-67 index usually decreases, even can be significantly reduced, but individual differences are large, and Ki-67 results after chemotherapy are also different.
Ki-67 is an indicator reflecting the degree of malignancy of the tumor, and the higher its value, the more active the tumor proliferation and the greater the possibility of proliferation.
Chemotherapeutic drugs are more lethal to actively proliferating tumor cells, and can reduce the division and proliferation ability of tumor cells and induce apoptosis of tumor cells. Therefore, after the proliferation of tumor cells slows down, the Ki-67 level will decrease, but the degree of decrease varies from person to person.
Chemotherapy has certain side effects on human body, patients need to pay attention to rest after chemotherapy, light diet, find Ki-67 index abnormalities need to consult a doctor in time, and follow the doctor’s instructions for medication.
