As we all know, radiotherapy, as one of the main means of tumor treatment, is an indispensable part of treatment for many patients. However, many patients are told to wait for a certain period of time before receiving the treatment, which makes them anxious and uneasy: it is said that early detection and early treatment, I have already suffered from a tumor, and if I continue to wait, will it not be even more delayed treatment and delay the condition? We can understand this kind of anxiety, but radiotherapy for tumors sometimes can not be “rushed”. Why do we say so? Let’s talk about it in detail. First of all, we all know that nowadays the treatment is emphasized on standardization and individualization. This standardization is of course important, for example, some tumors are very sensitive to radiotherapy, such as nasopharyngeal carcinoma, even if it reaches the advanced stage, 90% of the patients’ conditions can be effectively improved after precise radiotherapy; cervical cancer, even if it is in stage IV, the 5-year survival rate of the patients after radiotherapy can also reach more than 60%. But after all, not every tumor is suitable for radiotherapy, if there is no indication for radiotherapy, it is not standardized, but will bring unnecessary damage and burden to patients; in addition, the time of radiotherapy intervention for different tumors is not the same, like breast cancer, which is usually treated by surgery firstly, and then according to the staging to decide whether radiotherapy is needed or not, while nasopharyngeal carcinoma is a radiotherapy-based comprehensive treatment, and most of the patients need radiotherapy firstly. radiotherapy. Therefore, what disease and when is the appropriate time to choose radiotherapy should be in strict accordance with the guidelines and norms. Individualization is easier to understand. Different ages, genders and races will have their own conditions, and even two people from the same family with the same type of tumor will have differences between them. This requires individualized treatment to give patients more appropriate treatment. However, many people do not know that besides standardization and individualization, radiotherapy has entered the era of “precision”. Radiotherapy has its pros and cons. It can kill cancer cells, but it can also cause harm if not used properly. Nowadays, radiotherapy is becoming more and more precise, which can maximize the killing of tumor cells and minimize the damage of radiation to healthy tissues, but this “precision” requires a lot of preparatory work. For example, when a tumor patient comes to our clinic, we first need to clarify the stage of the tumor, check whether there are distant metastases of the tumor, and what is the physical condition of the individual before deciding whether or not to carry out radiotherapy. After deciding what kind of radiotherapy equipment to choose, CT localization, then target area outlining, hundreds of layers of CT layer by layer analysis, to develop a reasonable plan, so as to effectively kill the tumor without harming the surrounding tissues and organs. In addition to medical staff, we will also involve physicists, engineers and technicians to work together to develop the most reasonable radiotherapy plan. These preliminary tasks are heavily engineered and usually require several days of preparation. Studies have shown that a 1-2 week wait does not adversely affect the prognosis of tumor patients, but is more conducive to the development of the most appropriate individualized and precise radiotherapy plan; on the contrary, if radiotherapy is rushed without these preparations, it will do more harm than good. Of course, if there is a tumor emergency, the doctor will surely provide the fastest treatment for him. However, on the whole, tumor radiotherapy is a “rush” job, and patients need to know that doing it well is definitely more important than just doing it fast. In addition, nowadays there are many methods of radiotherapy, and many patients feel confused. We would like to briefly introduce them here. Gamma Knife: This is one of the most familiar radiotherapy means for the common people nowadays, which is generally suitable for tumors with relatively small lesions and regular shape. If the tumor is complex, the lesion is too large or the location is special, this method is not recommended. TOMO radiotherapy: this is the most precise radiotherapy equipment at present, suitable for patients with complex tumor morphology, location close to important functional areas (e.g. head and face), large tumors or multiple metastases. Therefore, patients should choose the most suitable radiotherapy method for themselves under the guidance of doctors, and then receive standardized, individual and precise radiotherapy with sufficient preparation, which will be extremely helpful for their prognosis.
