Efficacy of Traditional Chinese Medicine Patch Application at the Shenque (RN8) Acupoint in Cancer Patients Scheduled to Undergo Radiotherapy: A Study on Cancer-Related Fatigue and Heart Rate Variability

This randomized, double-blind, parallel-group controlled clinical trial aims to evaluate the effects of traditional Chinese medicine patch application at the Shenque (RN8) acupoint on cancer-related fatigue in adult cancer patients scheduled to undergo radiotherapy. Eligible participants will be randomly assigned to receive either a traditional Chinese medicine patch or a sham patch at the same acupoint. The intervention will be applied once daily for 2 hours, 7 days per week, for 2 consecutive weeks, for a total of 14 sessions. Fatigue severity, quality of life, heart rate variability, complete blood count, and skin safety will be assessed before and after the intervention.
