Objective: To summarize the academic experience of Professor Ouyang Chensheng in the pat-tern-differentiation based prescriptions for treating malignant lung cancer through the data mining technology; to explore the application of data mining technology in the traditional Chinese medicine (TCM) inheritance study, and to provide new insights to evaluate the adjunctive effect of TCM for patients with malignant cancers. Methods: We collected clinical records of out-patients in Shenzhen Hospital of TCM, who were diagnosed with malignant lung cancers, between December 2009 and July 2019. Chinese medicines in the prescriptions and the corresponding differentiated-patterns were extracted from the records and entered into the database, and further analyzed by Python and R respectively. The results were visualized by Cytoscape 3.7.1. The rules of TCM prescription and Chinese medicines commonly used for malignant lung cancers were summarized. Results: In the study, 2852 prescriptions were extracted consisting of 45,519 Chinese medicines. Through apriori algorithm based correlation analysis and frequency analysis, we found that Professor Ouyang Chensheng followed TCM principles of maintaining Zheng Qi, tonifying the spleen and kidney, resolving phlegm and removing blood stasis, and nourishing Yin and moistening lung in treating lung cancer. Liu Jun Zi decoction, Sanziyangqin, Erchen decoction, Qianjinweijing decoction, Xuefuzhuyu decoction, Xiaoqinglong decoction, and Shashenmaidong decoction were the commonest prescriptions in his treatments. In those prescriptions, Astragalus, Radix codonopsis, Poria cocos, Rhizoma atractylodes and Cornus officinalis were often added to tonify the spleen and kidney, as well as promote lung expectoration and nourish blood and Qi. Conclusion: Through data analysis, we find out Professor Ouyang Chensheng treated primary lung cancer on the principles of syndrome differentiation, tonifying Zheng Qi and removing pathogenic factors. These are important for treating malignant lung cancer by traditional Chinese Medicine. The data
