Acupuncture for Hot Flashes in Hormone Receptor-Positive Breast Cancer, a Randomized Controlled Trial

February 23, 2026 updated by: Weidong Lu, MB, MPH, PhD, Dana-Farber Cancer Institute
This research study is evaluating acupuncture, a medical therapy in which hair-thin, stainless steel needles are shallowly inserted into specific points to help the body's natural healing process, as a possible treatment to reduce hot flashes.

Detailed Description

Hot flashes are a sensation of sudden onset of body warmth, flushing and sweating. Hot flashes are common side effects of breast cancer treatments and can affect mood and daily life. Medications can help ease hot flashes, but many patients continue to experience symptoms despite these treatments.

Acupuncture is a complementary therapy in which, hair-thin, sterile disposable needles are inserted into various spots on the skin, with the goal of affecting body's natural healing system. Acupuncture has been tested in clinical trials in cancer patients and has been shown to be helpful in treating a number of side effects of cancer treatment, such as nausea and vomiting from chemotherapy. A few early studies have suggested that acupuncture may help to lessen hot flashes, but more information is needed about the benefits of acupuncture in breast cancer patients.

This study is being done to test whether acupuncture can help to reduce the number and intensity of hot flashes in breast cancer patients who are being treated with mediations such as tamoxifen and aromatase inhibitors, such as anastrozole (Arimidex), exemestane (Aromasin), and letrozole (Femara).

Description

Inclusion Criteria:

  • History of histologically or cytologically proven Stage I-III breast cancer with estrogen receptor positive with HER-2 positive or negative tumor;
  • Premenopausal or postmenopausal status;
  • Completed all primary chemotherapy and surgery;
  • Currently undergoing adjuvant hormonal therapy (e.g. Tamoxifen and/or Aromatase inhibitors) with or without ovarian function suppression for at least 4 weeks at study entry; the use of Trastuzumab after adjuvant chemotherapy is allowed;
  • Reported persistent hot flashes for at least 4 weeks AND more than 14 episodes of hot flashes per week (2 hot flashes per day) during the week prior to the study entry;
  • Age ≥ 18 years;
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1;
  • Signed informed consent

Exclusion Criteria:

Undergoing chemotherapy or planned surgery, chemotherapy, change doses and regimen of hormonal therapy during the study period;

  • Unstable cardiac disease or myocardial infarction within 6 months prior to study entry;
  • Uncontrolled seizure disorder or history of seizure;
  • Active clinically significant uncontrolled infection;
  • Use of acupuncture for hot flashes within 6 months prior to the study entry;
  • Uncontrolled major psychiatric disorders, such as major depression or psychosis;
  • Newly starting pharmacologic treatment of hot flashes such as selective serotonin reuptake inhibitors (SSRIs) and/or anti-convulsant for less than 4 weeks prior to study entry. Participants may continue with medications or therapies for the treatment of hot-flashes while participating in the study if the medication has been taking for more than 4 weeks prior to study entry AND the dose of the medication is going to be kept consistently during the study

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Immediate Acupuncture
  • Will receive a standardized acupuncture protocol for a 10-week period

Active Comparator: Delayed acupuncture
  • Will receive standard usual care without acupuncture for 10 weeks
  • Participants will cross over to receive the same acupuncture protocol for 10 weeks --10 sessions: once a week for 10 weeks before exiting the study

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline in Mean Weekly HFS Score Between Acupuncture and Usual Care Arms at the End of Week 10
Time Frame: 10 weeks
Daily Hot Flash Diary (DHFD) The DHFD is a measure of self-reported hot flash data that uses a diary to record the frequency and severity of hot flashes based on a 4-point scale (i.e., mild, moderate, severe, or very severe) to provide a hot flash score/index that reflects both number and severity of hot flashes (i.e., sum of the number of hot flashes multiplied by a weighted severity). Patients were asked to record daily for a week at five time points through the trial: baseline, week 5, week 10, week 15, and week 20. Negative changes would suggest improvements in number, type, or severity.
10 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Changes in the Total and Subscores in Functional Assessment of Cancer Therapy- Breast Cancer
Time Frame: 10 weeks
Changes in scores were calculated as (Week-10 - baseline). Since a higher score on any FACT-B subscale indicates better quality of life, a positive change would suggest that the patient's score improved during that time interval.
10 weeks
Changes in the Endocrine Symptom Subscale (ESS) in Functional Assessment of Cancer Therapy- Endocrine Symptoms (FACT-ES)
Time Frame: 10 weeks
The ESS is one subscale of the FACT-ES that assesses hormonal symptoms of endocrine therapy. The score ranges from 0-76 with higher scores indicating greater freedom from symptoms. Changes in scores were calculated as (Week-10 - baseline). Since a higher score reflects increased freedom from hormonal symptoms, a positive change would suggest that the patient's symptoms improved during that time interval.
