Pins And Needles To Help Nerve Pain Symptoms

Today's post from (see link below) is directly related to neuropathy as a result of treatment for breast cancer but as we all know by now (we do know don't we?) although the 'cause' in this case may be cancer, the treatment of the symptoms applies to most other neuropathies irrespective of the cause. The article is worth reading for everyone because it's realistic about current treatments and their shortcomings and not over-the-top about the benefits of acupuncture (supported by electro-stimulation which is also acupuncture). It suggests that acupuncture is worth looking into to help control neuropathic symptoms and backs it up with some study results. For the average neuropathy patient, it would be advisable to consult with your doctor first, if only because acupuncture doesn't come free and is only sporadically covered by medical insurances. There's the cost element but you should also be aware that not all acupuncture therapists are sufficiently qualified or experienced to help you properly. All sorts of things to think about here then but if you feel that acupuncture may help you then seek advice and do your research first. After that, you may be surprised at how an ancient medical treatment, backed up with modern technology, may be just as efficient as the pills you take daily.

Needling the Pain of Peripheral Neuropathy

SAN ANTONIO — For patients with breast cancer who have chemotherapy-induced peripheral neuropathy (CIPN), acupuncture may provide relief where other approaches have failed, according to a pilot study presented as a poster at the San Antonio Breast Cancer Symposium (SABCS) 2016.

"We were pleasantly surprised at how strong the effect was, especially in these women who had been suffering with this for years," said senior investigator Jennifer Ligibel, MD, from the Dana Farber Cancer Institute in Boston, Massachusetts.

"There are not many effective treatments available," added lead author and acupuncture specialist Wiedong Lu, MB, MPH, PhD, from the same institution.

Up to 97% of patients with breast cancer develop some degree of peripheral neuropathy during cancer therapy, particularly taxane-based treatment, and in roughly 30% the symptoms persist, said Dr Ligibel.

"Unfortunately for many women it is a problem that doesn't go away and there are not many effective therapies. There was a recent study looking at duloxetine but it only had effectiveness for the painful part of neuropathy whereas there are many different components of neuropathy, such as diminished sensation and changes in hot and cold sensitivity."

"Some studies from China suggest acupuncture might be helpful, but they are not focused on breast cancer and are mostly in diabetes and other types of neuropathy," added Dr Lu.

The study randomly assigned 40 patients with taxane-induced peripheral neuropathy ranging from a duration of 1.4 to 92.4 months to receive acupuncture therapy or usual care.

"The acupuncture was delivered for 8 weeks, on average twice a week, and usual care consisted of follow-up by their regular doctor without any particular intervention," explained Dr Lu.

All acupuncture was delivered according to a standardized protocol, with the addition of electrostimulation.

Overall, pain measures improved 33% and functional assessment improved 35% in the acupuncture group compared with controls, said Dr Ligibel.

The results were based on patient-reported outcomes collected at baseline and 8 weeks on the following:

Patient Neurotoxicity Questionnaire (PNQ);
European Organisation for Research and Treatment of Cancer Quality of Life Chemotherapy-Induced Peripheral Neuropathy (EORTC QLQ-CIPN20);
EORTC Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30); and
Brief Pain Inventory-Short Form (BPI-SF).

The study found significant differences between groups in the degree of improvement from baseline to 8 weeks.

Patients in the acupuncture group experienced significantly greater improvements in the PNQ summary sensory score (drops of 3.5 vs 2.8 points; P .001); the FACT-NTX summary score (improvements of 8.7 vs 1.2 points; P = .002); the EORTC QLQ-CIPN20 score (drops of 67 vs 39.9 points; P = .01); and the BFI-SF (drops of 6 vs 3.9 points; P = .01).

Asked by Medscape Medical News to comment on the findings, Jun Mao, MD, a breast cancer acupuncture specialist from the Integrative Medicine Service at Memorial Sloan Kettering Cancer Center, New York City, said, "CIPN is a huge problem and our group previously found close to 50% of women with breast cancer continue to experience CIPN years after treatment, which is associated with increased falls."

Dr Mao continued: "This pilot study shows the promise of acupuncture as a treatment for CIPN, where very few treatment options exist. Larger studies with longer follow-up and appropriate controls are needed to confirm the potential benefit of acupuncture as a standard treatment for CIPN."

Dr Ligibel agreed that an appropriate control condition is a challenge for this research.

"It's very complicated to figure out what is the best comparator because we just don't understand the mechanisms through which acupuncture works well enough to say what is a sham," she said.

Dr Lu, Dr Ligibel, and Dr Mao have disclosed no relevant financial relationships.
