Acupuncture for Insomnia in Breast Cancer Patients Undergoing Chemotherapy

The proposed study is a randomized, parallel-group, placebo-controlled, subject- and assessor-blind trial. It is designed according to CONSORT and STRICTA recommendations. The 138 subjects will be randomly assigned to one of the two arms using block randomization in a 1:1 ratio: (I) acupuncture treatment, and (II) sham treatment. In groups (I) and (II), acupuncture or sham acupuncture treatment will be given twice a week for 6 weeks (12 sessions). A maintenance tapering treatment schedule will then be applied once per month for 3 months (3 sessions). The primary outcome will be improvement in sleep quality as measured by the change of ISI after 6 weeks of treatment. Secondary outcome assessment tools will include PSQI, HADS, BPI, BFI, FACT-B, sleep diaries, drug diaries, blinding success questionnaire and reports of adverse events. The subjects will be scheduled for on-site follow-up assessments at 3 and 6 months after the last treatment. An intention to treat (ITT) approach will be used for data analysis.
