Key Finding
True acupuncture significantly reduced chemotherapy-induced peripheral neuropathy symptoms compared to sham acupuncture at week 8, with pain scores of 3.0 versus 6.0 on the VAS scale (p=0.001), though benefits did not persist at 4-week follow-up.
Breast cancer patients receiving paclitaxel chemotherapy often develop peripheral neuropathy, a painful nerve condition causing burning, tingling, and numbness in the hands and feet. Currently, doctors have limited options beyond reducing chemotherapy doses. Brazilian researchers conducted a study to test whether acupuncture could help relieve these symptoms.
The study included 60 women with early-stage breast cancer who developed nerve pain from paclitaxel treatment. Half received real acupuncture while the other half received sham acupuncture (placebo) once weekly for 8 weeks. Researchers measured pain levels, specific neuropathy symptoms, and quality of life at multiple time points.
Results showed that real acupuncture provided significant benefits by week 8. Women receiving true acupuncture reported less pressure pain, fewer shooting pains, reduced tingling and abnormal sensations, and lower overall pain scores compared to the sham group. On a standard pain scale, the real acupuncture group averaged a pain level of 3 out of 10, while the sham group averaged 6 out of 10. However, these improvements didn't persist four weeks after treatment ended, and quality of life scores didn't show significant differences between groups.
This study suggests acupuncture can provide meaningful short-term relief for chemotherapy-induced nerve pain during active treatment. The weekly sessions over 8 weeks appeared safe with no reported adverse effects. While benefits didn't last long after stopping treatment, acupuncture may offer a valuable option for managing symptoms while undergoing or recovering from chemotherapy. If considering acupuncture for chemotherapy side effects, seek a licensed acupuncturist experienced in oncology care.
This randomized, sham-controlled trial evaluated acupuncture for paclitaxel-induced peripheral neuropathy in 60 breast cancer patients (stages I-III). Participants received true or sham acupuncture weekly for 8 weeks. The primary outcome (Neuropathic Pain Symptom Inventory) showed statistically significant improvements in the true acupuncture group at week 8: pressure pain (0.11 vs 0.33; p=0.01), paroxysmal pain (0.13 vs 0.30; p=0.037), paresthesia/dysesthesia (0.21 vs 0.43; p=0.007), and total score (0.14 vs 0.33; p=0.02). VAS scores also favored true acupuncture (3.0 vs 6.0; p=0.001). No significant differences emerged in FACT-taxane quality of life measures or at 4-week follow-up (week 12), suggesting benefits don't persist post-treatment. Clinical takeaway: Weekly acupuncture over 8 weeks provides measurable symptomatic relief for CIPN during active management, though maintenance sessions may be needed for sustained benefit. This represents meaningful evidence for acupuncture as adjunctive care in oncology settings.

📌 Cognitive behavioral therapy and hypnosis have the strongest evidence for reducing vasomotor symptoms in breast cancer survivors, while acupuncture may provide modest benefit as an adjunctive nonpharmacological treatment option.
📌 Traditional acupuncture reduced hot flash and night sweat frequency by nearly 50% in breast cancer survivors taking tamoxifen, with sustained effects lasting at least 18 weeks after treatment ended.
