Abstract：Lung cancer is one of the malignant tumors with the highest cancer mortality in the world,with about 80％of cases being non-small cell lung cancer,which is the'first death'of cancer.Although the treatment of non-small cell lung cancer has made progress,there was no revolutionary breakthrough,making it the focus of scientific research personnel.With the expansion of the market demand for antitumor drugs,the number of patents has increased,containing valuable technical intelligence information.Through in-depth analysis of relevant patents in the field from 2003 to 2022,this study identifies and analyzes the core technology topics and co-occurrence relationships,and reveals the technology development trend based on the technology life cycle in terms of the distribution of patent applications and the evolution of technology topics,aiming to provide information support for the technology development in the field of non-small cell lung cancer from the perspective of information mining.
