Lung cancer KI67 is how much is low grade malignant

KI 67 proliferation index can reflect the malignant degree of lung cancer, generally lower proliferation index indicates low malignant degree, higher proliferation index indicates high malignant degree, but it needs to be judged comprehensively by other factors, and its detection results may also be affected by many factors. Generally, KI 67 has a low proliferation index. KI67 is a nuclear antigen associated with cell proliferation, and its expression level reflects the proliferative activity of tumor cells. In lung cancer, KI67 proliferation index is usually detected by immunohistochemistry. A higher KI67 proliferation index generally indicates stronger proliferative activity of tumor cells, faster tumor growth, and a relatively higher risk of invasion and metastasis. However, it should be noted that KI 67 proliferation index is only one of the indicators to evaluate the malignant degree of lung cancer, and it needs to be combined with other factors, such as tumor size, location, histological type and differentiation degree. In addition, KI67 proliferation index detection results may also be affected by a variety of factors, such as tumor heterogeneity, accuracy of detection methods, etc. For lung cancer patients, doctors usually consider a variety of factors to formulate treatment options, and according to the characteristics of the tumor and the patient's situation to choose the most appropriate treatment methods, including surgery, chemotherapy, radiotherapy, targeted therapy, etc. For lung cancer patients and their families, understanding the significance of tumor markers such as KI 67 proliferation index can help them better understand tumor characteristics and treatment options, but the final treatment decision should be made by professional doctors according to the specific conditions of patients. At the same time, patients and their families should actively cooperate with doctors to maintain a good attitude and improve treatment results and quality of life. In addition, for high-risk groups, such as long-term smoking, family history of lung cancer, chronic lung disease and other groups, lung cancer screening should be carried out regularly in order to early detection, early diagnosis, early treatment, improve the cure rate and survival rate of lung cancer.
