The latest statistics show that nearly 800,000 people die of lung cancer in China every year, ranking first in the incidence of tumors. Among them, non-small cell lung cancer patients account for about 80%. 1.First of all, we should determine the type of lung cancer. Lung cancer is divided into non-small cell carcinoma (NSCLC) and small cell lung cancer (SCLC) according to pathology, which account for about 75% and 25% of total lung cancer incidence respectively. Among them, non-small cell lung cancer is subdivided into squamous carcinoma, adenocarcinoma and large cell carcinoma. Small cell undifferentiated carcinoma is more sensitive to radiotherapy and chemotherapy, but is prone to recurrence. Overall speaking, lung cancer is best treated by surgery. 2. Secondly, it depends on the stage of lung cancer. Internationally, a unified standard is used to divide lung cancer into four stages: I, II, III and IV. Among them, stage I and II are characterized by smaller tumors, easier to be removed and no distant metastasis, which can be treated by surgery, radiotherapy and chemotherapy, and the final healing effect is better. Stage III, on the other hand, is based on surgery combined with radiotherapy and chemotherapy. Stage IV lung cancer cannot be operated, and only radiotherapy and chemotherapy can be used. 3. Thirdly, it depends on the patient’s physical condition. It is mainly to check whether the patient’s vital organs, heart, liver, lung, kidney function, blood picture are normal and there are no important underlying diseases such as diabetes and myocardial infarction. The best treatment method can be found by combining the above overall conditions. Chemotherapy can be used in cases that are not suitable for surgery and radiotherapy, and in cases that have relapsed after surgery and radiotherapy or have had systemic metastases. In addition, chemotherapy can be used as an adjuvant treatment before surgery and as a means of consolidating the efficacy after surgery and radiotherapy. As follows: 1. Early or middle stage lung cancer (without distant metastasis) is best treated mainly by surgery (about 20%), which is reliable and safe and can significantly prolong the survival rate by removing the cancer tumor once and solving the tumor problem fundamentally. 2.Small cell lung cancer is a more powerful type of lung cancer with rapid development, short course and high mortality. Focal type can be removed surgically, and chemotherapy or radiotherapy can be added after surgery; extensive type can be treated with chemotherapy + radiotherapy + immunotherapy (or treated with Chinese medicine), which can prolong patients’ life and improve their quality of life. 3.Non-small cell lung cancer (squamous carcinoma, adenocarcinoma, squamous adenocarcinoma) Surgery is preferred. 4.For all types of advanced lung cancer who have lost the chance of surgery, chemotherapy is the main treatment, together with traditional Chinese medicine and local radiation therapy. 5.For those who have local metastasis and have indications for surgery, chemotherapy can improve the surgical resection rate if given before surgery. 6.Other For those who are old, poor in health, unwilling to operate, afraid of radiotherapy and chemotherapy and have economic difficulties, Chinese medicine treatment can be used. If the economic condition is good, molecular targeted therapy can be adopted. Regardless of the type of lung cancer, comprehensive treatment should be preferred, the efficiency of which is 15%-55% higher than that of single treatment, which can greatly increase the five-year survival rate and improve the quality of life of patients. 7. Targeted drug therapy such as ERSA or Erlotinib can be used if the body cannot tolerate it or the effect is not satisfactory.
