According to authoritative reports, the current incidence rate of lung cancer in Guangdong is close to 50/100,000, which is a high incidence level by internationally accepted standards. In recent years, the incidence of lung cancer in our city has been “following” the province. In the past five years, the number of lung cancer inpatients has increased significantly, and the trend is younger, with the proportion of female patients increasing. Dr. Lu Wenqiang, deputy director of cardiothoracic surgery of the hospital, suggests that people with long-term smoking history, occupations closely related to lung cancer-causing substances, long-term exposure to kitchen fumes and family history of lung cancer should preferably undergo low-dose spiral CT lung cancer screening once a year to achieve early detection and treatment. Among the causative factors of lung cancer, smoking is undoubtedly the most important one. Based on one pack of cigarettes per day, if a person has been smoking continuously for more than 20 years, he or she is classified as a high-risk group for lung cancer, and his or her potential risk of developing lung cancer is much higher than normal people. In October 2013, the World Health Organization officially announced that the risk of lung cancer from atmospheric pollution is equal to that of tobacco. The results of this study are reflected in the lung cancer patients seen at the city’s People’s Hospital, as the number of lung adenocarcinoma cases closely related to atmospheric pollution has been high in the past five years. In addition, small indoor environmental pollution, including second-hand smoke, kitchen fumes, benzopyrene and other harmful substances in renovation materials are also the “culprits” of the increasing incidence of lung cancer in women in recent years. ”During the cooking process with gas, the maximum temperature can reach 300°C. Toxic substances in cooking oil are released with high temperature and the particles are precipitated, which can affect human health, especially the lungs, and increase the chance of lung cancer in the long-term exposure group.” Housewives and chefs in the restaurant industry, who are exposed to kitchen fumes more frequently, are among the affected groups. 64-row 128-layer spiral CT enables low-dose imaging screening According to the results of a study published in an international authoritative journal, the cure rate of lung cancer can reach 70% to 90% with surgery at stage I, while at stage III a, the cure rate of surgery is only 15%. “It is evident that the most important factor determining the efficacy of surgical treatment for lung cancer patients depends on the timing of treatment.” As early stage lung cancer lacks clinical symptoms, more than 85% of lung cancers that appear and then detected are in the middle and late stages. Therefore, to detect early lung cancer as early as possible, it is crucial to rationally choose the right medical examination method. At present, the screening methods for lung cancer include sputum test, serum tumor marker test, X-ray and low-dose spiral CT. Among them, sputum screening needs to further improve the sensitivity, while reliable serum tumor markers with high specificity are still being explored. Although X-ray radiography has the advantages of convenience, low cost, time saving and low radiation dose, it lacks sensitivity for the diagnosis of small lung cancer less than 3 cm. By a combination of price, examination accuracy, radiation dose and many other aspects, low-dose spiral CT has now become the preferred way for many citizens to screen for lung cancer. “The 64-row 128-layer spiral CT introduced by our hospital can achieve low-dose imaging screening and detect tiny lung tumors within 0.5 cm, with a complete scan of the whole chest taking only 2.5 seconds, and the radiation dose of chest scan is only 26% of that of conventional CT, and the price of more than 200 yuan per time is also accepted by the general public if they choose the medical checkup package. “ The general public should form a correct concept of lung cancer prevention and treatment as early as possible, therefore, high-risk people over 50 years old should undergo low-dose spiral CT lung cancer screening once a year. Minimally invasive” and “targeted drugs” are popular keywords for lung cancer treatment, and in 2007, People’s Hospital took the lead in carrying out TV thoracoscopic surgery to treat lung cancer in the city. Lv Wenqiang said that TV thoracoscopic surgery for lung cancer treatment only requires opening 2-4 small holes of about 1 to 2 cm in diameter in the chest wall, and the surgery is performed by camera and instruments under the lumpectomy video equipment. Compared with the previous chest incision of more than 20 cm, it greatly reduces the patient’s pain and facilitates easy and effective sputum removal and rapid recovery of limb function after surgery. Because of the small trauma and high safety, some high-risk patients with advanced age or cardiopulmonary insufficiency are also given the opportunity to have surgery, in a sense, expanding the indications for lung cancer surgery.
