The Effect of Acupuncture on Cancer-Related Cognitive Difficulties

April 17, 2026 updated by: Memorial Sloan Kettering Cancer Center

Effect and Mechanism of Acupuncture for Cancer-related Cognitive Difficulties (ENHANCE)

The purpose of this study is to test whether acupuncture can improve cognitive difficulties and insomnia in survivors of breast cancer. Researchers will compare the effects of real acupuncture with those of placebo acupuncture and wait-list acupuncture. This study will also look at insomnia's link to cognitive difficulties.

All study participants (receiving real acupuncture, placebo acupuncture, or wait-list acupuncture) will complete study questionnaires and/or have cognitive testing at Weeks 0, 4, 10, 14 and 26. After the Week 26 visit, your participation in this study will end. If you are assigned to receive placebo acupuncture or wait-list acupuncture, you will have the option of receiving up to 10 real acupuncture treatments within the six months after the study finishes.

  • Masking: Double

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Acupuncture
The intervention will consist of 10 acupuncture sessions over 10 weeks using the standardized, semi-fixed protocol.
Each participant will receive 10 treatments of acupuncture (real or sham) over the course of 10 weeks (i.e. one treatment a week) with a +/- 14-day window.
Will follow patients for 26 weeks from baseline and collect assessments at baseline and Weeks 0, 10, and 26. Average time to complete the surveys is 30 minutes, which has been judged to be acceptable with minimal missing data; 20 minutes of these 30 minutes will be completed during the neurocognitive battery. Patients will complete PROs online using Research Electronic Data Capture (REDCap) or over the phone with the CRC. Biospecimens will be collected in person at assessment visits. The neurocognitive battery will be administered remotely.
Placebo Comparator: Sham Acupuncture (SA)
The intervention will consist of 10 acupuncture sessions over 10 weeks using the standardized, semi-fixed protocol.
Each participant will receive 10 treatments of acupuncture (real or sham) over the course of 10 weeks (i.e. one treatment a week) with a +/- 14-day window.
Will follow patients for 26 weeks from baseline and collect assessments at baseline and Weeks 0, 10, and 26. Average time to complete the surveys is 30 minutes, which has been judged to be acceptable with minimal missing data; 20 minutes of these 30 minutes will be completed during the neurocognitive battery. Patients will complete PROs online using Research Electronic Data Capture (REDCap) or over the phone with the CRC. Biospecimens will be collected in person at assessment visits. The neurocognitive battery will be administered remotely.
Experimental: Wait-List Control
During the 26-week waiting period, the CRC will contact patients in the WLC group at the same frequency as the acupuncture groups with respect to data collection. Patients in the WLC group will continue to receive their standard medical care as prescribed by their oncologists/primary care physicians. WLC patients will be compensated with real acupuncture treatments after Week 26 (end of study).
Patients in the WLC group will continue to receive their standard medical care as prescribed by their oncologists/primary care physicians.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
cognitive difficulties
Time Frame: 26 weeks
measured by the Functional Assessment of Cancer Therapy - Cognitive Function (FACT-Cog) instrument. FACT-Cog is a 37-item questionnaire with 4 subscales: perceived cognitive difficulties, impact on quality of life, comments from others, and perceived cognitive abilities. The FACT-Cog perceived cognitive impairment subscale (Cronbach's α 0.94) will be the primary outcome for the study. A subscale score is calculated by summing the 18 items of the subscale. The subscale score ranges from 0 to 72.
