RESUMEN
Based on literature research and Delphi expert consensus method, the important acupoints for cancer pain was summarized to provide evidence basis for the formulation of Clinical Practice Guide of Acupuncture in the Treatment of Cancer Pain. Through systematic search of Chinese and English databases, 28 clinical studies regarding acupuncture for cancer pain were included. The acupoint selection methods and high-frequency acupoints were summarized and analyzed. Based on this, a Delphi questionnaire was designed and two rounds of questionnaire survey on 30 experts in acupuncture and tumor related fields in China and abroad were conducted. As a result, it was suggested that the individualized acupoint selection should be adopted for acupuncture treatment of cancer pain, with Zusanli (ST 36), Hegu (LI 4), Taichong (LR 3), Sanyinjiao (SP 6), Yanglingquan (GB 34) and ashi points as the main acupoints. Combined with clinical research evidence and expert consensus, the important acupoints for cancer pain were identified. However, clinical acupoint selection still needed further research and refinement.
