Evidence Explorer · MS-N264 · Auricular acupuncture · dysgeusia during platinum chemotherapy · Appraised November 7, 2026
A small pilot trial reported better taste-alteration and quality-of-life scores with auricular acupuncture, but only 49 of 73 randomized participants completed the study and absolute effect sizes were not available in the abstract.
Evidence at a glance
- Benefit signal: Preliminary symptom signal, with substantial missing data and no confirmed clinically meaningful threshold.
- Certainty: Very low. This was a pilot, attrition was high, blinding and control details were incompletely available, and multiple secondary outcomes were tested.
- Risk context: Ear needling can cause local pain, bleeding, infection or cartilage inflammation. Taste change can also signal infection, oral problems, zinc deficiency or other treatment effects.
- Cancer-control relevance: This is supportive-care evidence. It does not test tumor response, recurrence or survival.
What was studied
Seventy-three people receiving platinum-based chemotherapy were randomized to auricular acupuncture or control; 49 completed the study. The primary outcome was severity on a chemotherapy-induced taste-alteration scale. Quality of life, anxiety and depression were secondary outcomes. The exact ear points, session frequency and analyzed denominators by arm were not fully verified from the accessible abstract.
What the study found
The acupuncture group had statistically lower discomfort, general taste-alteration and total taste-scale scores than control (all p<.05). Several quality-of-life domains and anxiety/depression also favored acupuncture. Absolute between-group differences, confidence intervals and proportions reaching a meaningful improvement were not reported in the abstract.
What this does not establish
The result does not establish improved nutrition, weight maintenance, chemotherapy completion or durability. With 24 of 73 participants not completing, attrition could materially change the estimate. Taste improvement is not evidence of anticancer activity.
Safety and practical context
Persistent dysgeusia deserves oral examination and nutrition assessment. Avoid ear needling with local dermatitis, infection or marked bleeding risk. Strategies such as flavor adaptation, temperature changes, plastic utensils for metallic taste and dietitian support may be more practical.
Questions for the care team
- Could oral thrush, mucositis, dry mouth, medication or micronutrient deficiency be contributing?
- Would an oncology dietitian help protect intake and weight while symptoms continue?
- What were the exact ear points and infection-control procedures used by the practitioner?
