1.Recognize what is tumor When it comes to comprehensive treatment of tumor, we have to mention what tumor is. With the continuous progress of scientific research and clinical practice, our understanding of tumor is also changing day by day. Nowadays, tumor is not simply a “painful lump” as described by Hippocrates. This means that the treatment of tumor cannot be killed once and for all as we thought in the past, but has become a long-term treatment, just like the treatment of hypertension and diabetes, which requires long-term monitoring, regular review and the development of localized treatment plans according to the emerging conditions. All these actions are aimed at maintaining the disease like tumor in a more stable state, neither damaging the patient’s life and health nor bringing unnecessary side effects due to over-treatment. This point for diabetic and hypertensive patients is to maintain the stability of blood sugar and blood pressure and avoid fluctuation; for tumor, it is to avoid the progression, recurrence and metastasis of tumor. 2.What are the methods to treat tumors? Nowadays, as the understanding of tumor deepens and diversifies, the treatment methods for tumor have become various, from organ transplantation and combined organ removal to gene sequencing and molecular targeting, which can be described as a hundred schools of thought and comprehensive. Among these methods, surgery, chemotherapy and radiotherapy are still the most important ways to treat tumors today. Surgery, as the name implies, is to physically remove the tumor and some of the surrounding tissues from the body as a whole, which can be said to be direct, crisp and immediate, but the disadvantage is that there are limitations of indications, and many patients may have already lost the opportunity of surgery at the time of diagnosis. Chemotherapy is actually a drug treatment, i.e. drugs are delivered into the body by oral, drip or injection, and then play a chance to kill the tumor. Compared with surgery, chemotherapy often works on the whole body, so that tumor cells have nowhere to hide, but this kind of carpet bombing often kills a thousand enemies and damages eight hundred, and is often limited by side effects in clinical practice. Radiation therapy is to irradiate the solid tumor through physical rays, which has considerable benefits for local treatment, but it is also limited by the tolerance of surrounding organs and causes certain degree of side effects. In addition, radiofrequency ablation, interventional embolization chemotherapy, immunotherapy, biological therapy and other modalities also have their own advantages and limitations. 3.Why choose comprehensive treatment? Comprehensive treatment of tumor is not the simple superposition of different treatment methods, but refers to the formulation of planned and targeted treatment plan according to the location, nature, severity of tumor and patient’s own physical condition, including the selection of treatment modality, arrangement of treatment timing and grasp of treatment cycle, so as to enable patients to get higher cure rate, longer survival rate and better quality of life. better quality of life. The core of comprehensive treatment is to tailor the treatment to the local situation, i.e. to choose the most appropriate treatment for the patient at the most appropriate time. For example, if a colorectal cancer patient comes to the clinic and is evaluated to have no clear metastasis and can be treated surgically, then surgical resection is a more suitable method, just like eliminating the enemy’s fortress in one fell swoop in the war; the postoperative pathology indicates that there is metastasis of lymph nodes in colorectal cancer, which is like the enemy’s fortress has been eliminated, but there are still some scattered defeated soldiers in nearby villages, towns or country roads. Although the carpet bombing has eliminated the enemy, our own troops have also suffered losses, and our bodies are weak and have no energy. It can be seen that the comprehensive treatment of tumor is like a well-organized and orderly battle plan, which can treat the tumor and eliminate the disease by the most effective method and with the least loss, and then obtain the most favorable benefit for the patient. According to the specific conditions of patients’ tumors and personal physical state, the most suitable treatment methods are selected and the most reasonable arrangement is formulated, so that various methods are arranged in an orderly and complementary manner, which can not only treat tumor lesions exactly and effectively, prevent recurrence and metastasis, but also protect patients’ own health and safety to the greatest extent. If the last century was dominated by destructive treatment, then this century will be the era of comprehensive tumor treatment.
