Lung cancer is a kind of cancer with a relatively high degree of malignancy. Clinically, the mortality rate of lung cancer is very high. For lung cancer patients, in addition to early surgical treatment, some adjuvant chemotherapy should be done after surgery. To improve the quality of life of patients, what are the indications for chemotherapy after lung cancer surgery?

　　Indications of postoperative radiotherapy for lung cancer are:
　　1, I and II cases cannot be treated with conventional postoperative radiotherapy;
　　2. Cases with residual clinical tumors after surgery;
　　3. Patients with positive tumors on the margin of the surgical specimen;
　　4. No lymph node dissection was performed during the operation;
　　5. Pathology of surgical specimens Examination revealed hilar and (or) mediastinal lymph node metastasis, especially those with tumors that have penetrated the lymph nodes and entered the surrounding tissues.
　　For the same tumor, some people have obvious curative effect, while others have little effect. This is because of differences in individual genes and mutations in tumor genes, resulting in different drug effects. The top three hospitals in China generally recommend genetic testing of tumor drugs, formulate drug programs with higher efficacy and lower toxicity, and seek symptomatic targeted drugs. For those with a family history of cancer, the risk can be checked by tumor susceptibility gene detection, which is of great clinical significance for tumor prevention.
　　Through the above introduction, I believe everyone has a certain understanding of the indications for chemotherapy after lung cancer surgery. Experts say that after chemotherapy, lung cancer patients will have symptoms such as vomiting and loss of appetite. This is the family of patients. Dietary conditioning, more nutritional supplements, improve the body''s immune capacity, in order to better treat lung cancer.
