Malignant tumor is a neoplastic organism with unrestricted growth and invasive and metastatic characteristics. The treatment of tumors is about individualized and comprehensive treatment guided by the principles of evidence-based medicine. The so-called standardized treatment first requires the evaluation of the patient’s condition. After clinical and pathological diagnosis, the scope of tumor invasion, whether the tumor has metastasis, which sites have metastasis, as well as the size of each lesion and whether the function of the corresponding organ is damaged, etc. should also be detected. After comprehensive evaluation, the tumor is staged and the patient is observed for other comorbidities. For example, whether the cancer patient also suffers from diabetes, cardiovascular disease, other medical diseases, infection, etc., all these must be checked. Then, according to the above examination results, multidisciplinary teams (MTD) (including medical oncology, surgery, radiotherapy, imaging, pathology, nursing, pharmacy, nutrition, etc.) will discuss and formulate a standardized and comprehensive treatment plan (based on the Code, Guidelines, Pathway, etc.) together. That is, the means used are based on science, not just experience. The content involves diagnosis, treatment and follow-up, etc. The current problem is greater: excessive examination, treatment or inadequate (examination is mainly excessive, treatment is mainly inadequate). Only about 55% are truly standardized enough.
