The emergence of immunotherapy has made lung cancer patients see new hopes, but there are also blind obedience problems. Recently, at the 14th China Lung Cancer Summit held in Guangzhou, Professor Wu Yilong, chairman of the China Society of Clinical Oncology and director of the Guangdong Lung Cancer Institute, called for a calm treatment of lung cancer. A survey of the participants showed that 59.3% of lung cancer specialists had been exposed to immunotherapy. Wu Yilong told reporters that the immune system can not only be activated but also suppressed. If the immune system is likened to a car, cancer cells have evolved a special means of sneaking on the brakes. The improvement of immunotherapy is that it can adjust the "brake" to a reasonable range, and if necessary, "refuel" to kill cancer cells. Wu Yilong said that since the 2013 Science magazine listed immunization as a major advancement, the global wave of immunotherapy has started, and the challenge has followed. First, most lung cancer patients, especially some gene mutations, are ineffective. The overall effectiveness of immunotherapy is less than 20%. Scientists are developing effective "precautionary markers for efficacy" to develop a "value scoring system" for oncology drug therapy, hoping to screen out those who can benefit from immunotherapy. Second, some patients may have serious toxic side effects, and some side effects have not been seen by doctors. The side effects of immunotherapy may occur in various parts, including pneumonia, colitis, hepatitis, pancreatitis, rash, thyroid abnormalities, etc., as well as fatal myocarditis, acute interstitial pneumonia, acute respiratory distress syndrome. After a few patients received immunotherapy, the tumor not only did not shrink, but the growth rate was more than twice that before treatment. Third, the efficacy of immunotherapy may be persistent compared to targeted therapy and chemotherapy. For example, about 20% of patients with advanced melanoma in Europe and the United States can achieve clinical cure and become a "super survivor." But this does not mean that there is no resistance to immunotherapy. Guangzhou Zhongzhinan Supply Chain Co.,Ltd. , https://www.zhongzhinanlighting.com
