Worldwide, lung cancer has become the leading cause of cancer deaths in both men and women. 2005 saw an estimated 500,000 new cases of lung cancer in China (330,000 in men and 170,000 in women); 2007 saw an estimated 213,380 new cases of lung cancer in the United States (114,760 in men and 98,620 in women) and 160,390 deaths (89,510 in men and 70,880 in women). 160,390 (89,510 for men and 70,880 for women). Only 15% of patients survive for more than 5 years after lung cancer diagnosis. Lung cancer treatment begins with controlling risk factors Lung cancer is a unique disease, with the tobacco industry as its primary cause, and more than 85% of lung cancers are caused by active or passive smoking; according to the Surgeon
According to the Surgeon General, both active and passive smoking can cause lung cancer, as well as other cancers, including esophageal, laryngeal, pharyngeal, and oral cancers. Smoking can damage almost every organ in the body, and people who live with smokers have a 20-30% increased risk of developing lung cancer. Therefore, quitting smoking and controlling smoking in public places are important measures to prevent the occurrence of lung cancer. Radon gas, a decay product of radium, is radioactive and is the second major cause of lung cancer. Asbestos is an inorganic compound known to cause cancer. Exposure to airborne asbestos fibers increases the risk of lung cancer, especially among smokers. In addition, recurrent lung infections, tuberculosis secondary to scar formation, family history, and exposure to carcinogens such as bis(chloromethyl)ether, polycyclic aromatic hydrocarbons, chromium, nickel, and organic arsenic compounds are all risk factors for lung cancer. Secondly, timely screening and treatment for risk groups Lung cancer is still the main cause of cancer deaths worldwide, and the main reason for the failure to improve the efficacy of lung cancer treatment is that many lung cancers are diagnosed at a late stage. Therefore, the key to lung cancer treatment is early diagnosis. Therefore, lung cancer screening has been gaining more and more attention as an important part of lung cancer prevention and treatment and improving lung cancer survival rate. Common symptoms of lung cancer include cough, dyspnea, weight loss or chest pain, but some patients do not have obvious self-conscious discomfort in early stage. Therefore, in most cases, chest X-ray is still the main means of screening for lung cancer-prone people, but the detection rate is limited due to the impact of film taking and reading technology. The International Early Lung Cancer Action Plan (I-ELCAP), by evaluating the early detection of lung cancer in patients with lung cancer risk factors through annual spiral CT screening, has shown that spiral CT has been shown to detect most early stage I lung cancers, and the 10-year survival rate of stage I lung cancer can be as high as 92% if timely surgical resection is performed, as opposed to patients with untreated stage I lung cancer who will die within 5 years. Thirdly, timely and appropriate treatment is the key to improve the survival rate of lung cancer after surgery Stage I and II patients are most likely to be cured by surgical methods, because in actual clinical practice, only less than 25% of these patients are treated. The National Comprehensive Cancer Network (NCCN) of the United States is the most important clinical network for oncology,
The NCCN Clinical Practice Guidelines in Oncology (Chinese version), first edition, 2008, clearly states that surgery provides the best chance of cure for stage I and II patients; among patients with completely resected non-small cell lung cancer, several clinical trials have been conducted to evaluate the effect of adjuvant chemotherapy and found that adjuvant chemotherapy can improve the survival of patients with early stage lung cancer; currently, for stage III patients who cannot be operated, synchronous chemotherapy radiotherapy appears to be superior to sequential chemoradiotherapy for stage III patients who are inoperable; for stage IV patients in good physical condition, the use of platinum-containing chemotherapy regimens would be beneficial; and Chinese medicine has advantages for improving the quality of life of lung cancer patients.
