RESUMO
BACKGROUND: Maintenance acupuncture is advocated by clinicians after successful clinic-based acupuncture. We aimed to assess the effectiveness of maintenance acupuncture in the management of cancer-related fatigue (CRF); treatment delivered by therapists or self-acupuncture/self-needling was compared with no maintenance treatment. METHODS: Breast cancer patients who participated in a randomized trial of acupuncture for CRF management (reported elsewhere) were re-randomized to receive an additional four acupuncturist-delivered weekly sessions; four self-administered weekly acupuncture sessions (self-needling); or no acupuncture. Primary outcome was general fatigue (Multidimensional Fatigue Inventory). Mood, quality of life and safety were also assessed. RESULTS: In total, 197 patients were re-randomized, with 65 to therapist-delivered sessions, 67 to self-acupuncture/self-needling and 65 to no further acupuncture. Primary outcome scores were equivalent between the therapist-delivered acupuncture and self-acupuncture (P > 0.05). A non-significant trend in improving fatigue was observed at the end of 4 weeks in the combined acupuncture arms (P = 0.07). There was no impact on mood or quality of life of the further acupuncture sessions at 18 weeks beyond the improvement observed in initial trial. CONCLUSION: Self-acupuncture is an acceptable, feasible and safe maintenance treatment for patients with CRF. However, overall, maintenance acupuncture did not yield important improvements beyond those observed after an initial clinic-based course of acupuncture. TRIAL REGISTRATION NUMBER: NCT00957112.
