A Pilot Study of Acupuncture for Chemotherapy-induced Peripheral Neuropathy in Breast Cancer Patients

Dana-Farber Cancer Institute57 enrolled

Overview

This study is being done to evaluate the potential benefits of using acupuncture to reduce symptoms of tingling, burning, numbness and pain in the hands and feet of women with peripheral neuropathy after completion of chemotherapy for breast cancer.

Chemotherapy drugs used to treat cancer can cause temporary or permanent damage to the nerves in the hands and feet, a condition called "chemotherapy-induced peripheral neuropathy". The most common symptoms of chemotherapy-induced peripheral neuropathy are pain, tingling, burning or numbness sensation, which can lead to balance problems or trouble using fingers or pick up/holding things. These symptoms often last months to years after the completion of chemotherapy. Medications and nutritional supplements can ease the symptoms of chemotherapy-induced peripheral neuropathy, but many patients continue to experience symptoms despite these treatments. Acupuncture is an intervention in which hair-thin, stainless steel needles are shallowly inserted into specific points on the skin, with the goal of influencing the body's natural healing system. Acupuncture has been studied in clinical trials in cancer patients and has been shown to be effective for various conditions including chemotherapy-induced nausea and vomiting. A few preliminary studies have suggested that acupuncture may help to reduce symptoms of peripheral neuropathy, but more information is needed about the benefits of acupuncture in breast cancer patients This study is being done to evaluate the potential benefits of using acupuncture to reduce symptoms of tingling, burning, numbness and pain in the hands and feet of women with peripheral neuropathy after completion of chemotherapy for breast cancer. This research study will help to determine the benefits of acupuncture for the treatment of chemotherapy-induced peripheral neuropathy. The study will also look at two different acupuncture schedules to determine whether patients derive benefits from lower and higher dose acupuncture treatments.

Related medications are: gabapentin, pregabalin, nortriptyline, amitriptyline, duloxetine, venlafaxine; lidocaine, opioid tramadol and other narcotics; NSAIDs; glutamine, glutathione, vitamin E and vitamin B12; * Age ≥ 18 years; * Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1; * Adequate hematological function: neutrophil count \>1.0 x109/L, platelet count \>50x109/L; * Signed informed consent. Exclusion Criteria: * Patients with any of the following criteria will not be eligible for the study: * Unstable cardiac disease or myocardial infarction within 6 months prior to study entry; * Wearing a pacemaker or implantable cardioverter-defibrillator; uncontrolled seizure disorder; * History of pre-existing peripheral neuropathy prior to chemotherapy, including alcoholism, vitamin B deficiency, diabetes, HIV, congenital neuropathy, toxic neuropathy; * Peripheral neuropathy caused by tumor infiltration or compression of spinal nerves or surgical trauma; * Pregnancy or potential pregnancy and nursing; * Active clinically significant uncontrolled infection; * Prior use of acupuncture for CIPN within 6 months prior to study entry; * Patients with uncontrolled major psychiatric disorders, such as major depression or psychosis, will not be eligible for this trial. Patients with a history of depression or anxiety who are stable on or off psychiatric medications will be eligible.

Outcomes

Primary Outcomes

Response Rate from Baseline in PNQ Score

The PNQ includes two questionnaire items: one asking about sensory neurotoxicity and the other asking about motor neurotoxicity. The questionnaire items correspond to the neurotoxicity questions included in the NCI-CTCAE. PNQ grades range from grade A (no neuropathy) to grade E (very severe neuropathy). Answer options will be coded 0=A to 4=E, with a higher score indicating more severe CIPN

Time frame: Baseline, Week 8

Secondary Outcomes

Changes in FACT/NTX subscale baseline to 8 weeks

Time frame: Baseline, 8 Weeks

Changes in EORTC-QLQ-CIPN20 subscale Baseline, 8 Weeks

Comprised of three subscales assessing sensory, motor, and autonomic symptoms. Subscale scores will be calculated and linearly transformed to a 0 to 100 scale, with higher scores suggesting more severe symptoms. Changes from baseline (8-week - baseline) between the intervention arms for each subscale will be of interest.
