Abstract：Objective：To discuss the point selection rules of acupuncture and moxibustion for cancer pain by data mining. Methods：The Chinese literature on acupuncture and moxibustion for cancer pain in CNKI，Wanfang and VIP was retrieved from the establishment of the databases to May 30，2020. The documents in line with the standards were entered into Excel database and the data was analyzed with SPSS20.0 statistical software. Results：A total of 71 literature was retrieved. Among the acupuncture prescriptions without distinguishing specific cancers， stomach channel is the most commonly used channel，followed by large intestine channel and spleen channel. The five acupuncture points in order of their frequency from more to less are Zusanli(ST 36)，Hegu(LI 4)，Ashi，Sanyinjiao(SP 6) and Neiguan(PC 6) points，and the specific points are mainly five transport points， he- sea point and lower he- sea points. In the acupuncture prescriptions for cancer pain in different viscera， the commonly used acupuncture points for gastric cancer pain are Zusanli(ST 36) and Zhongwan(CV 12) points；the common points for lung cancer pain are Neiguan(PC 6)，Feishu(BL 13) and Zusanli(ST 36) points；the common points for liver cancer pain are Taichong(LR 3)， Qimen(LR 14)， Ganshu(BL 18) and Sanyinjiao(SP 6) points. The selected channels are mainly the channels of the diseased viscera and the bladder channel，while the specific points are mainly backshu point，front-mu point and he-sea point. The cluster analysis was carried out with high frequency points whose frequency is greater than or equal to five， and finally four kinds of results were obtained. Conclusion： Acupuncture and moxibustion treats cancer pain，with Zusanli(ST 36)，Hegu(LI 4)，Ashi，Sanyinjiao(SP 6) and Neiguan(PC 6) points being the basic point prescriptions. According to the cancer pain of different viscera，the basic point prescriptions modified with symptoms should be combined based on the combination of the he-sea point and front-mu point in the channel of the diseased viscera and the corresponding back-shu point of bladder meridian.
