"Cancer Registration in China 2012 Annual Report" shows that over the past 30 years, lung cancer mortality increased by 465 percent in China, has replaced liver cancer to become the first cause of cancer death China. Guangdong Provincial People's Hospital Cancer Center, Institute for lung cancer, Guangdong Province, a department director, said Yang Jin-ji, an increase of lung cancer incidence in Chinese cities soon, this environmental pollution in large cities may exist with a degree of correlation.
Quote online consultation, many patients think surgery is the only means to cure early stage lung cancer. In fact, if the poor cardiopulmonary function and systemic state has heart disease , diabetes and other chronic wasting disease can not tolerate surgery patients, it is recommended for accurate radical radiotherapy or other localized invasive treatment. "No matter which treatment method using postoperative follow-up are required to be regulated." Yang Jin-ji reminder.
Molecular targeted therapy for gene mutation
According to Yang Jin-ji, director of introduction, in recent years, the Guangdong Provincial People's Hospital, Guangdong Lung Cancer Institute genotyping diagnosis of lung cancer, molecular targeted therapy, as well as systematic mediastinal lymph node dissection , and other aspects of innovative research results confirmed the epidermis growth factor receptor (EGFR) mutations in populations using molecular targeted drug treatment was significantly higher than the efficacy of chemotherapy.
Although the efficacy of molecular targeted drugs is better, but there are strict limits to adapt to the crowd. First, patients must have associated mutations; followed by the gene mutation, ie, "target", there can be "quasi-life" of the "target" treatments. For example: detecting EGFR gene mutations in patients treated with the drug targeting tumor efficiency up to 70% to 80%. Treatment of lung cancer, it is necessary to extract DNA of tumor cells for gene detection, genotyping, discovered the existence of "target" may be targeted for treatment.
Healthy ≠ anti-cancer screening
Yang Jin-ji said that there is no correlation in patients with mutations, chemotherapy is preferred. In addition, Yang Jin-ji reminder, most of the early lung cancer have no symptoms, general health examination of the chest X-ray project, it is difficult to detect early lung cancer. Under normal circumstances, there is a serious history of smoking, cough, hemoptysis , history of chronic lung disease, lung cancer often have a family history of respirable dust and other high-risk populations, it is necessary to do a low-dose spiral CT annually.
