Diabetes and hypertension, as they are known, are chronic diseases that require frequent contact with a doctor and long-term medication to control the disease. These patients are able to work and live as usual while undergoing treatment. Recent studies have shown that malignant tumors, which were once considered “terminal”, are now considered chronic diseases that can be controlled. The methods of cancer control include surgery, radiation therapy, chemotherapy, biologically targeted therapy, Chinese herbal medicine …… and so on. According to the patient’s specific situation, the aim is to control the tumor to the maximum extent or even make the tumor disappear, while preserving? The rational use of these treatments is the comprehensive treatment of tumor. There are several methods to control tumor: Surgery: it is a local treatment. For early stage tumors, surgery is to completely remove the tumor and remove the structures near the tumor that may be invaded, such as adjacent lymph nodes. For intermediate and advanced tumors, surgery can remove part of the tumor, reduce the tumor load in the patient’s body, alleviate the adverse symptoms brought by the tumor, and maintain the patient’s quality of life. For patients with very advanced tumors, surgery may also provide symptom relief. In clinical practice there may be some other cases where surgery can be used for palliative treatment. Radiation therapy: It is also a local treatment. There are radical radiotherapy, palliative radiotherapy, preoperative radiotherapy, postoperative radiotherapy, etc. Some tumors are inoperable and sensitive to radiation, and radical radiotherapy can be used. Some patients whose tumors cannot be resected can use preoperative radiotherapy to make the tumor somewhat smaller and increase the success rate of surgical resection. Some patients have local regional metastasis or residual after surgery, postoperative radiotherapy can be used to supplement surgery. Some patients can neither undergo surgery nor tolerate radical radiotherapy and have very obvious local adverse symptoms, so palliative radiotherapy can be used. The specific method of radiotherapy to be used will be determined according to the patient’s condition needs. Chemotherapy: Both anti-tumor drugs are used to treat the tumor systemically or regionally. General intravenous chemotherapy is a systemic treatment. Interventional chemotherapy is to make the local organs or tissues where the interventional chemotherapy drugs are highly concentrated, and through blood circulation, the drugs finally reach the whole body. In some cases of pleural and peritoneal effusions with cancer cells, intracavitary injection of drugs can also be used to give local treatment. In a few cases, local injection of chemotherapeutic drugs can be used. There are several types of chemotherapy: chemotherapy alone, preoperative (before radiotherapy) chemotherapy or neoadjuvant chemotherapy, adjuvant chemotherapy (after surgery or radiotherapy), palliative chemotherapy, etc. Because chemotherapy drugs are toxic to several systems in the body, it is up to the doctor to determine whether the patient can receive chemotherapy based on his or her condition. Molecular targeted therapy: a new and promising treatment method. At present, there are two major categories of molecular targeted drugs available in China: one is anti-vascular endothelial growth factor drugs, which are currently recommended to be used in combination with chemotherapy; the other is anti-epidermal growth factor receptor drugs, which are mainly used for second-line treatment after chemotherapy has failed. These drugs are not effective against all tumors, but are selective. They are also not effective for all patients, and should be selected according to the situation. These drugs are expensive and should be carefully selected for the right patients to avoid wastage. The real efficacy of these drugs needs to be accumulated with more cases. With proper selection of the above treatments, patients can live long term even if the tumor is still present in their body. Choosing the right treatment at the right time can protect the patient’s quality of life while controlling the tumor. It enables the patient to survive for a long time with the treatment as if he/she had other chronic diseases.
