Two years ago, Mr. Duan, an 80-year-old man living in Hebei, started to cough and sputum, and was diagnosed with lung cancer by chest CT and PET-CT examination at the local hospital. He was given anti-infective and symptomatic treatment with oral traditional Chinese medicines, which provided some relief at that time but did not last long. Four months later, Mr. Duan began to experience dyspnea, which gradually worsened, with occasional intermittent hemoptysis and left-sided chest and back pain, etc. A follow-up chest CT examination in the hospital revealed that the proximal and distal shadows of the left main bronchus were present, and the left main bronchus was occluded. For further treatment, he came to Beijing and transferred to our hospital at the end of 2015. Octavo method of central type airway Staging of the lesion After admission, the scleroscope was inserted through the mouth under general anesthesia, and neoplasm was seen in the lumen of trachea 7 area, irregular shape, intratracheal+tubular wall type, which completely occluded the left main bronchus, and was given to the lapper to lasso, and CO2 freezing and biopsy forceps to clamp the tumor, which was mostly eliminated, and the lumen of the left main bronchus was completely revealed. The base of the tumor was located in trachea 7 and 8, and the length was about 3 cm. the pathology was: “trachea 7” low-differentiated adenocarcinoma. After the surgery, several genes were tested, and no gene mutation was found. Radiotherapy and chemotherapy were given to remove the residual tumor, and Mr. Duan’s symptoms of breathlessness were significantly relieved. Mr. Duan’s symptoms of breathlessness were significantly relieved. He was followed up for one year after treatment and his condition was stable. Tracheal Tumor: Trap Instrument Treatment Left Upper and Lower Lobe Openings Lung Cancer (after treatment) Lung cancer is a common malignant tumor, which often leads to some symptoms in the patient’s body. Generally speaking, the early symptoms of lung cancer include cough, hemoptysis, chest pain, shortness of breath and other respiratory system manifestations. To achieve ideal treatment effect, the principle of individualized treatment must be followed. Suitable methods should be chosen according to the pathology and staging of lung cancer. Many patients with advanced lung cancer lose the opportunity of surgical treatment, but minimally invasive treatment (thoracoscopic surgery, tracheoscopic treatment, targeted therapy, etc.) still has the opportunity to be performed. Minimally invasive treatment is not only less traumatic, with precise local curative effect, but also can have a radical effect on early stage lung cancer; it can also reduce the tumor load in the advanced stage, which can improve the quality of patient’s survival and protect the function of normal tissues and organs to the maximum extent at the same time.
