Clinical Study on the Prevention and Treatment of Postoperative Metastasis of Lung Cancer by Fuzheng Quxie Recipe

In this study, investigators actively explored the establishment of a combined Chinese and Western medicine prevention and treatment programme in response to the urgent clinical need for the lack of effective diagnostic and therapeutic options for postoperative patients with stage IIA-IIIA non-small cell lung cancer who are clinically negative for the expression of driver genes. 1. To objectively evaluate the efficacy of "Fuzheng Quxie Recipe" in preventing and treating postoperative metastasis in stage IIA-IIIA non-small cell lung cancer with negative expression of driver genes, including its effects on disease-free survival, quality of life, and regulation of immune function of the patients, by means of a clinical study in accordance with international standards; 2. To test the immunohistology, circulating tumour cells and tiny residual lesions of the patients, and to screen out the population with the advantages of Chinese medicine treatment. Based on this, investigators will establish an efficacy prediction model including the evaluation of peripheral immune function status and the expression level of circulating tumour cells, in order to improve the level of precision treatment after radical lung cancer surgery. 3. Through conducting high-level clinical research in line with international standards, obtaining high-level evidence-based medical evidence, screening the advantageous populations of Chinese medicine in treating lung cancer metastasis, and forming a standardised diagnostic and treatment plan/guidelines on Chinese medicine or international guidelines on combining traditional Chinese and Western medicines for the prevention and treatment of post-surgical metastasis of lung cancer that can be promoted and applied, so as to provide a solid scientific basis for the transformation of clinical results and the development of new medicines, and to promote the improvement of the efficiency of the prevention and control of lung cancer as a whole.
