Every year, China’s esophageal cancer patients account for more than half of the world’s esophageal cancer patients, and it is of great significance to improve the cure rate of esophageal cancer to protect the health of our people. The traditional treatment for esophageal cancer is mainly surgery. Generally speaking, surgery is mainly applied to early and middle stage esophageal cancer patients, which only accounts for one third of all esophageal cancer patients, which means that two thirds of patients are not suitable for surgery due to the late stage of the disease. In addition, due to the large trauma of surgery, surgery should be especially cautious for patients with upper esophageal cancer, especially cervical esophageal cancer, as the quality of life of these patients will be significantly reduced after surgery. If these patients are operated, the quality of life of these patients will be significantly reduced after operation. Moreover, it is not suitable for patients with high age or important organ diseases such as cardiopulmonary diseases. The results of a large number of clinical studies have shown that the application of modern radiotherapy technology in the treatment of esophageal cancer can completely achieve similar curative effects with surgery, while patients can avoid the trauma of surgery. At present, in Europe, America, Japan and other developed countries, the standard treatment for early esophageal cancer can choose modern radiotherapy or surgery, while the only standard treatment for upper esophageal cancer and inoperable advanced esophageal cancer is modern radiotherapy. In our country, people have long formed the concept that only surgery can cure esophageal cancer, and they may be skeptical that modern radiotherapy can cure esophageal cancer without surgery. For this reason, I have cured many inoperable advanced esophageal cancers. To cite a typical example, five years ago, there were two patients who suffered from esophageal cancer at the same time, coming from the same village in north of Jiangsu Province, applying modern radiotherapy to treat one of the patients with the surname of Jiang, who had metastasis to supraclavicular lymph nodes, and could not be operated because of late stage of the disease (although the patient strongly demanded for the operation), and the other patient was operated at a relatively early stage of the disease, and at the end of the treatment, the patient who had been operated passed away after going back to his home for two months, and the patient is still alive. The patient is still alive today. During the follow-up visit, the patient surnamed Jiang said with emotion: “Fortunately, I didn’t have the surgery at the beginning, otherwise I might not be able to see you, Dr. Chen, anymore. ……” This example is not intended to say that the curative effect of radiotherapy is better than that of surgery, but merely to show that modern radiotherapy is also capable of curing esophageal cancer. This example is not to say that radiotherapy is more effective than surgery, but only to show that modern radiotherapy can also cure esophageal cancer. Modern radiotherapy is a comprehensive treatment method with high technological content. First of all, in terms of radiotherapy itself, it contains the most advanced radiotherapy technology in the contemporary world, such as image fusion technology and image-guided three-dimensional conformal intensity-modulated radiotherapy technology, etc. The former can precisely target the location of the tumor. The former can accurately lock the location and invasion range of the tumor, and the latter can accurately project the radiotherapy dose to the tumor and minimize the irradiation of normal tissues around the tumor, so as to achieve the “triple-excision treatment” of precise positioning, precise planning, and precise irradiation, which is the same as the military practice of “precise striking and targeted elimination”, and is the most advanced radiotherapy technology in the world. It is a revolutionary breakthrough in radiotherapy technology. Secondly, another development of modern treatment is the integrated treatment of radiotherapy and chemotherapy drugs, i.e. concurrent radiotherapy and chemotherapy, which refers to the treatment of chemotherapy drugs at the same time on the day of radiotherapy, and its main purpose is to improve the killing of tumor cells by radiotherapy. Studies have shown that concurrent radiotherapy can increase the efficacy of treatment by two times. A large number of clinical researches show that the curative effect of applying modern radiotherapy technology plus concurrent radiotherapy and chemotherapy in treating esophageal cancer is almost equal to that of surgery.
