Theoretically, a few patients with early stage lung adenocarcinoma have small lesions and the tumor is confined to one lobe of the lung, so timely and proper treatment to remove the cancerous lesions and prevent recurrence can lead to radical cure i.e. the cure rate of early stage lung adenocarcinoma can reach 100%. However, it is clinically proven that even in early stage lung adenocarcinoma, due to the decline of immune function and metastasis of cancer cells to near and distant sites, even though simple surgery or other treatments are performed, many cases will soon have local or systemic recurrence symptoms. Lung adenocarcinoma treatment methods: 1.Surgical treatment and radiation therapy Radiation therapy includes intracavitary and extracorporeal irradiation; the equipment used includes radium ingots, X-ray machines, cobalt guns, gas pedals, and various “photon knives and X-knives” developed in recent years. It was only in 2011 that the most advanced radiotherapy equipment in the world was introduced into China: TOMO radiotherapy (spiral tomotherapy system), which has enabled many patients to receive real top-notch technical support for treatment and to get rid of the disease. It can be used as adjuvant treatment before and after surgery to improve the success rate of surgical treatment. 2.Chemotherapy is also a common treatment for lung cancer. It has an important position in the treatment of lung cancer. According to the current view, whether early or late stage, whether surgery or radiotherapy, it is necessary to combine with chemotherapy to improve the survival rate. For small cell lung cancer with clear diagnosis, a course of induction chemotherapy should be given before surgery and then surgical resection. Chemotherapy should be continued after surgery. Adenocarcinoma, as well as large cell carcinoma, can be treated with regular chemotherapy after surgery. For advanced stage or lesions that cannot be surgically resected, local infusion chemotherapy can also be administered via bronchial artery. 3.Biological gene therapy is also effective in the treatment of lung adenocarcinoma. Biogene therapy is mainly based on the theory that there is a close relationship between tumor and blood vessel formation. The main purpose of biogene therapy is to stop the growth of blood vessels by using anti-angiogenesis inhibitors, to make the capillaries atrophy and to cut off the nutrient supply to the tumor. Lung cancer is usually treated with radiation therapy as an adjuvant treatment before and after surgery. Patients with lung cancer must maintain strong confidence and actively carry out treatment. Patients must proactively cooperate with doctors for better recovery. What is the cure rate of lung cancer? Firstly, if it is early stage lung cancer, we can completely cure it clinically through a comprehensive treatment based on surgery, so that these lung cancer patients can avoid death. If the disease has progressed to the middle stage, we can also prolong the life of the patient through surgery, chemotherapy, radiotherapy, etc., and the patient will not be one step away from death. Secondly, if the lung adenocarcinoma develops to the terminal stage, all the symptoms will be manifested and very serious, which is the case of lung adenocarcinoma. At this time, we can also reduce the pain of lung cancer patients and improve their living standard through various treatments. For sure, having lung cancer does not mean death. If it is detected in time and treated effectively, the disease can be completely eliminated. It also requires us to have a positive attitude to face the disease. With the intervention of medical technology, the quality of life of lung cancer patients will be improved. How to effectively extend the life of patients? The first one is to minimize the number of cancer cells in the body; the second one is to make the immune system strong enough to defend itself. After cancer treatment, there are still residual cancer cells in the body, which is the basis of recurrence and metastasis. Therefore, only by strengthening the immune defense function of the body can the body remove or inhibit the residual cancer cells in the body, which can truly prevent recurrence and metastasis.
