According to recent survey data show that China now every four people died, one person died of cancer. However, after years of efforts of the medical profession, the cancer cure rate has increased significantly, some of the early cure rate of up to 90% of patients. According to the World Health Organization reports that the current overall cure rate of about 45% of cancer (China is only 25-30%), which constitutes a contribution of 22% for the surgery, 18% radiotherapy, chemotherapy 5%, three is still the treatment of cancer The main resort. Wherein about 65-75% of patients in need of treatment in different stages of the radiotherapy, Thus, radiation therapy (radiotherapy for short) an important role in cancer therapy.
So, what exactly radiotherapy efficacy? Specific to different cancer patients, radiotherapy should pay attention to what matters? How future trends and prospects of radiotherapy?
Comprehensive treatment is the key
"At present, China cancer cure rate is lower than the world average, in large part because many patients fear surgery or radiotherapy, the total would like to solve the problem with medication, therapy results missed a golden opportunity." Instituted some public misunderstanding exists to radiotherapy, Professor He Guangrong shout, "Be sure to scientific understanding of radiotherapy, radiotherapy seems double-edged sword, but with the increasing levels of radiation, radiotherapy side effects have been small for most cancer patients, radiation therapy is very timely and important."
Treatment order is important
In the combined treatment basis, in order to achieve the best effect, the actual circumstances of each patient's cancer, sequence selection on various treatments will vary. In radiation therapy, for example, some patients need before surgery, while others required after surgery, radiotherapy and some just can. Then, specific to cancer treatment, preoperative radiotherapy and postoperative radiotherapy and radiotherapy What difference does it apply?
With nasopharyngeal carcinoma , for example, radiation therapy has become its preferred treatment. Currently, early nasopharyngeal carcinoma radiotherapy can be cured, even with advanced nasopharyngeal carcinoma, radiotherapy can also get good results, 5-year survival rate of around 70%. For head and neck cancers, such as tongue cancer , especially supraglottic laryngeal cancer , radiation therapy can also be achieved through the healing effect. And, compared with surgery, radiotherapy and surgical treatment can be achieved in addition to the same effect, the biggest benefit is also reflected in, it does not cause head and neck tissue defects caused due to surgery and functional damage. Especially high demand for vocal pronunciation patients are generally recommended radiation therapy.
In addition, for some cancers, such as cervical cancer , early skin cancer and early lung cancer , etc., can be achieved with the use of radiotherapy surgery therapy comparable to or even better than the treatment effect of surgery, good operating results accurately
Radiotherapy future development towards what direction will it?
The latest conformal radiotherapy is one of the most advanced radiotherapy methods. With this technique, you can make a high radiation dose region in three dimensions consistent with the shape of the tumor, so that you can increase the radiation dose in the tumor while fully protecting normal tissues around the tumor, thereby enhancing the efficacy of concurrent radiotherapy-induced decrease disease. Therefore, the technology has been widely used in head and neck cancer, lung cancer, esophageal cancer , straight colorectal and prostate cancer treatment and the like.
Currently, due to the level of doctors and medical equipment and other factors, compared to 45 percent of the world's cancer cure rates, there is a lot of room for improvement, the overall cancer treatment level of 26% of the urgent need to improve cancer cure rates. "In the treatment Technically, not a big gap between us and now need to be trained radiation therapists, and the efficient allocation of medical resources in local hospitals and work hard." Professor He Guangrong concluded. Abundant medical resources compared to cities, district level hospitals should uphold the "Ningquewulan" principle, a number of high-quality medical hospital centralized allocation of resources, the main specialized cancer diseases, ensuring optimal treatment for patients with cancer erected value
Tips: Can cancer treatment is the key to see whether early detection, early treatment, and the patient's state of mind is also a great relationship, only a positive attitude, reasonable treatment to restore health, access to new life.
