Standardized treatment refers to a planned, step-by-step, sequential and rational comprehensive treatment based on the biological characteristics, disease stage and development trend of the tumor, and multidisciplinary cooperation in formulating the treatment plan. Once a patient is diagnosed with cancer, the best treatment plan should be selected by an oncologist according to the condition. Standardized and reasonable first treatment is crucial to the success of treatment. The principles of treatment are: 1. Emphasis on early treatment: early detection, early diagnosis and early treatment is the key; 2. Emphasis on first treatment: improper first treatment will easily lead to local recurrence and increase the difficulty of secondary treatment; 3. Integrated treatment: multidisciplinary treatment is the current internationally recognized treatment policy for cancer. The existing effective treatment methods include surgery, radiotherapy, chemotherapy, biological therapy and targeted therapy, each with its own characteristics, which should complement each other’s strengths and weaknesses; 4. individualized treatment: the key is to make a clear diagnosis, to administer treatment according to the disease type, disease stage and individual differences, and to achieve reasonable, timely and appropriate treatment in order to achieve survival, quality and safety, and to improve survival and cure rates; 5. moderate treatment: tumor treatment should Prevent under-treatment and over-treatment, inappropriate treatment measures or over-aggressive measures can cause serious consequences. Multidisciplinary experts use the existing treatment means and the latest achievements of evidence-based medical research to jointly formulate reasonable and planned treatment plans for different patients, rationalize the use of medical resources, avoid unhelpful treatment, make it more in line with the actual condition of each patient, maximize the cure rate of patients and improve the quality of life.
