You can’t simply rely on the number of Ki67 positive rate to judge the recurrence rate of tumor, the probability of tumor recurrence is related to the malignant degree of the tumor, early and late disease, and treatment. Ki67 is an immunohistochemical index commonly used in malignant tumors, which is one of the markers of cell proliferation activity, mainly reflecting the proliferation activity of tumor cells. Generally speaking, the higher the value is, the stronger the proliferation activity of the tumor cells, the higher the degree of malignancy, which means that the tumors have stronger invasive and metastatic ability, and vice versa, the lower the degree of malignancy is, but it doesn’t mean that the recurrence rate of tumors is low. Tumor recurrence refers to the reappearance of tumor tissues of the same pathological type in the original tumor site or other sites after treatment, and the reasons for recurrence are related to the high degree of malignancy of the tumor, late discovery of the disease, incomplete treatment for the first time, and the low immunity of the body, etc. Therefore, the probability of recurrence of the tumor can not be solely based on the indicator of Ki67. Tumor treatment should be standardized under the guidance of specialists, and should not be superstitious or avoid medical treatment in order to avoid delaying the condition.
