Somatic Acupressure for Symptom Cluster Management in Breast Cancer Survivors

Fatigue, sleep disturbance, and depression commonly co-occur in breast cancer (BC) survivors, forming a significant cluster known as the fatigue-sleep disturbance-depression symptom cluster (FSDSC). The FSDSC correlates notably with decreased everyday functioning and quality of life (QoL). Currently, there are no targeted pharmacological interventions available for alleviating the FSDSC in BC survivors. Additionally, concerns arise regarding the risks of drug-related adverse events and potential interactions with ongoing antineoplastic regimens when relying solely on pharmacological treatments. Consequently, nonpharmacological adjunct interventions have emerged as an alternative method. Somatic acupressure (SA) presents a promising nonpharmacological intervention for managing the FSDSC due to its advantages, including self-administration with minimal effort and time, lower cost, good tolerability, and minimal instruction required from clinical staff. However, the effectiveness of SA in improving the FSDSC in BC survivors remains uncertain. The proposed study follows the Medical Research Council (MRC) Framework for Developing and Evaluating Complex Intervention (the MRC Framework) to develop an evidence-based SA protocol to help with the better management of the FSDSC in BC survivors. The first phase identified and validated the most effective acupoint formula with the optimal SA duration and frequency based on multiple evidence bases. Subsequently, a well-designed phase II randomized controlled trial (RCT) was conducted. It demonstrated the feasibility of an evidence-based SA intervention protocol and its potentially positive effects on the FSDSC in BC survivors. The encouraging results, therefore, warrant further investigation through a large-scale RCT to ascertain the effects of SA on the FSDSC among BC survivors. The whole program is designed following the MRC Framework. Hence, the current study aims to evaluate the effects, safety, and cost-effectiveness of the SA protocol for managing the FSDSC in BC survivors through a phase III RCT.
