Brief Summary

The proposed randomized control trial will evaluate auricular point acupressure (APA) on chemotherapy-induced neuropathy (CIN), rigorously considering point specificity and placebo effects by integrating self-report measures, psychophysical measures (QST), endogenous biomarkers (cytokines), and neuro-imaging to investigate APA's efficacy and underlying mechanism(s).

Detailed Description

Chemotherapy-induced neuropathy (CIN)-pain, numbness, or tingling distributed in the hands and feet-produces persistent symptoms affecting sensation and balance in cancer survivors. Up to 50% of cancer survivors still suffer CIN 6 years after treatment. Duloxetine, the only recommended drug by the American Society of Clinical Oncology, was found to be superior to placebo but improved CIN by only 0.73 points (0-10 scale). No effective treatment for CIN has been established except exercise, with an effect size of \<0.508. Opioids relieve CIN pain, but long-term use is strongly discouraged due to opioid overuse.

The investigators propose to test auricular point acupressure (APA), an innovative and scalable solution developed from auricular acupuncture. APA is a non-invasive (needleless) and active treatment for patients with pain, whereas acupuncture is an invasive (using needles) and passive treatment (administered by a licensed practitioner). In APA, small seeds are taped on specific ear points by a skilled provider and patients press on the seeds to stimulate ear points three times daily, three minutes per time, for a total of nine minutes per day. APA provides pain relief within 1-2 minutes after ear stimulation and sustains pain relief for one month after a 4-week APA intervention. APA is popular in Taiwan, China, and Europe. Though its use is sparse in the U.S., a limited number of clinical trials have supported APA in pain management.

Usual Care ControlUsual CareUsual Care arm will continue with their usual care.
Virtual Auricular Point Acupressure (vAPA)Virtual training for seed placement and APAThe vAPA arm will self-administer APA by placing the seeds according to the video instruction found in the self-guided smartphone application for understanding and administering APA. Participant and/or a caregiver will follow the video instruction on seed placement and will receive one zoom session for APA coaching one week after the baseline visit.
Auricular Point Acupressure (APA)In-person training for seed placement and APAThe APA arm will receive in-person weekly treatments and a self-guided smartphone application with videos for understanding and administering APA. The APA arm will receive one in-person seed placement and a training for the participant or their caregiver to place the seeds on the ear points, as well as one zoom meeting 1 week after the first visit to coach participant and/or caregiver on seed placement.
Auricular Point Acupressure (APA)Post-training zoom session for seed placement and APA coachingThe APA arm will receive in-person weekly treatments and a self-guided smartphone application with videos for understanding and administering APA. The APA arm will receive one in-person seed placement and a training for the participant or their caregiver to place the seeds on the ear points, as well as one zoom meeting 1 week after the first visit to coach participant and/or caregiver on seed placement.

Participant and/or a caregiver will follow the video instruction on seed placement and will receive one zoom session for APA coaching one week after the baseline visit.
Primary Outcome Measures
NameTimeMethod
Change in numbness as assessed by the Brief Pain InventoryUp to 4 months

Numbness will be assessed using the revised Brief Pain Inventory (BPI). The scale ranges from 0 (no numbness) to 10 (severe numbness).

Change in pain severity as assessed by the Brief Pain InventoryUp to 4 months

Pain severity will be assessed using the revised Brief Pain Inventory (BPI). The scale ranges from 0 (no pain) to 10 (severe pain).

Change in tingling as assessed by the Brief Pain InventoryUp to 4 months

Tingling will be assessed using the revised Brief Pain Inventory (BPI). The scale ranges from 0 (no tingling) to 10 (severe tingling).

Change in physical function as assessed by Patient-Reported Outcomes Measurement Information System (PROMIS) 29Up to 4 months

Physical function will be assessed using the subscale of physical function, Patient-Reported Outcomes Measurement Information System (PROMIS) 29. The subscale of physical function has a range of 5 (unable to function) to 20 (able to function without difficulty).

Secondary Outcome Measures
NameTimeMethod
Change of pain sensitivity as assessed by Qualitative Sensory Testing (QST)Up to 4 months

Pain sensitivity will be measured by QST. The QST battery consists of light touch sensation as assessed by the Semmes-Weinstein Monofilament Test (SWMT), threshold and tolerance, temporal summation, and conditioned pain modulation (CPM). The threshold responses will be conducted in randomized and counterbalanced order; CPM will always occur last. Temporal summation measures, CPM, and after-sensation responses to these measures will be combined to create the central sensitization index for use in statistical analyses.

Change of brain activity as assessed by fMRI NeuroimagingUp to 1 month

All Functional magnetic resonance imaging (fMRIs) will be acquired on a 3.0 Tesla Siemens Prisma System (Siemens Medical Solutions, Erlangen, Germany) at The Johns Hopkins Hospital Radiology Building, Baltimore. Blood Oxygen Level Dependent functional images will be acquired using 2D gradient echo echo-planar imaging to cover the whole head \[repetition time (TR)=2000ms, echo time (TE)=30ms, flip angle 90 degrees, acquisition matrix 64x64x40, slice thickness 4mm\]; 300 volumes will be acquired for each fMRI data point. All imaging systems are connected to the hospital picture archiving and communication system. Each scan will take approximately 20 minutes.

The investigator will report the functional connectivity networks of the Pearson correlation coefficient which ranges from 0 (no correlation) to 100 (perfect correlation).

Change in anti-inflammatory cytokines as assessed by serum cytokine biomarkersUp to 4 months

A 15-mL blood sample will be drawn at each time point and blood samples will be collected using standard phlebotomy procedures and will be transferred and processed at the Johns Hopkins School of Nursing (JHSON) basic science laboratory (coagulation and serum separation by centrifugation). Serum will be stored at -80 °C at the JHSON. Once the study collection is completed, a panel of cytokines will be measured in diluted samples using the bio-plex pro-human chemokine panel.

The investigator will report the number of participants that have a change in any anti-inflammatory cytokines level greater than 50 percent of baseline
