Lung cancer is the malignant tumor with the highest incidence and mortality rate among men in China, and the incidence of lung cancer continues to rise. Lung cancer treatment currently includes surgery, drug chemotherapy (including targeted therapy), radiation therapy, immunotherapy, local palliative therapy and Chinese medicine, etc. Patients are often confused when seeking medical treatment and inevitably seek treatment for their diseases, while on the other hand, doctors’ lack of knowledge about lung cancer disease may also cause delays in lung cancer treatment to a certain extent. In order to prolong patients’ lives and improve life treatment as much as possible, the latest and most effective proven treatment methods should be combined, and after determining the main treatment direction for each lung cancer patient, specific methods should be tailored for each patient so that each lung cancer patient can receive the best treatment, so individualized treatment under standardized lung cancer treatment is of great importance. Due to the lack of early symptoms of lung cancer and the relative backwardness of China’s overall medical level, many lung cancer patients in China are already suffering from distant metastasis when they are diagnosed and have lost the opportunity of surgery. Therefore, the current lung cancer treatment is a comprehensive treatment mainly based on surgery. Patients with surgical conditions often need to supplement chemotherapy or even radiotherapy after surgery, or to operate after preoperative chemotherapy or radiotherapy, while patients without surgical conditions or whose tumors recur after surgery need to be treated mainly with chemotherapy or radiotherapy, combined with immunotherapy, Chinese medicine and various local symptom reduction treatments. For patients with lung cancer, the first step is to: 1. clarify the clinical lung cancer stage: patients should undergo whole-body examination (avoid repeating the examinations that have been done recently in outside hospitals), including chest X-ray and CT, head MRI, ultrasound (or CT) of abdominal organs, whole-body bone scan to exclude distant metastases, and for patients with good economic condition, whole-body PET-CT can be considered instead of the above examinations, and pathological specimens should be obtained as much as possible The diagnosis is clearly established (tracheoscopy or bronchoscopic ultrasound-guided puncture EBUS or CT percutaneous lung puncture), and finally the clinical staging is completed, which is to determine whether the patient is in the early, middle or late stage and to guide the patient to the next step of treatment. Those with diagnostic difficulties are consulted by the lung cancer diagnosis and treatment team composed of multiple disciplines in the hospital. 2.Implementation of standardized treatment: ① Patients with non-small cell lung cancer eligible for surgery are subjected to standardized surgery, and postoperative adjuvant chemotherapy and radiotherapy are decided according to pathology and lymph node metastasis. For clearly diagnosed lung cancer with extensive mediastinal lymph node metastasis on the operation side or locally advanced lung cancer, preoperative neoadjuvant chemotherapy and radiotherapy can be performed, and those with reduced tumor size will continue to undergo standardized surgery. ②Patients who are too old and frail or have poor cardiopulmonary function to withstand surgery can receive local treatment such as stereotactic radiotherapy, radiofrequency ablation (freezing or radioactive particle implantation). ③Non-small cell lung cancer that has metastasized is treated mainly with chemoradiotherapy, and appropriate chemotherapy (traditional chemotherapy or targeted therapeutic agents) is selected based on the genetic test results of this patient’s pathological specimen. Patients with pleural metastases accompanied by malignant pleural fluid are treated with chemoradiotherapy and other comprehensive treatments after controlling pleural fluid by thoracoscopic pleural exfoliation or thermocirculatory perfusion chemotherapy. Advanced patients with tumor obstruction of airway are treated with endotracheal tumor removal for airway recanalization and continue to receive chemoradiotherapy and other comprehensive treatments to prolong life after relieving symptoms. Central type small cell lung cancer is treated with sequential chemoradiotherapy or concurrent chemoradiotherapy, supplemented with whole brain irradiation to prevent brain metastasis. Small cell lung cancer of peripheral type that is operable can be considered for standardized surgery and postoperative adjuvant chemotherapy/radiotherapy. 3. Regular outpatient review and departmental follow-up: Postoperative patients should have a comprehensive examination such as chest CT and abdominal ultrasound once every 6 months within 2-3 years, and once a year thereafter. Standardized treatment of lung cancer is increasingly emphasized, but each patient’s condition is different. Under the standardization of general treatment principles, individualized treatment methods are formulated for each patient’s condition, so that each lung cancer patient can receive the best treatment suitable for him/her, cure lung cancer or prolong life and improve life quality.
