Acupuncture eases radiation-induced dry mouth in cance...(re's benefits include the suggestion tha...),Health

The M. D. Anderson study included 19 patients with xerostomia who had completed radiation therapy at least four weeks earlier. The patients were given two acupuncture treatments each week for four weeks. The acupuncture points used in the treatment were located on the ears, chin, index finger, forearm and lateral surface of the leg. All patients were tested for saliva flow and asked to complete self-assessments and questionnaires related to their symptoms and quality of life before the first treatment, after completion of four weeks of acupuncture, and again four weeks later.

The twice weekly acupuncture treatments produced highly statistically significant improvements in symptoms. Measurement tools included: the Xerostomia Inventory, asking patients to rate the dryness of their mouth and other related symptoms; and the Patient Benefit Questionnaire, inquiring about issues such as mouth and tongue discomfort; difficulties in speaking, eating and sleeping; and use of oral comfort aids. A quality-of-life assessment conducted at weeks five and eight showed significant improvements over quality-of-life scores recorded at the outset of the study.

"In this pilot study, patients with severe xerostomia who underwent acupuncture showed improvements in physical well-being and in subjective symptoms," Dr. Chambers said. "Although the patient population was small, the positive results are encouraging and warrant a larger trial to assess patients over a longer period of time."

Garcia said that a phase III, placebo-controlled trial is planned and is currently under review. She also noted that in other studies, the M. D. Anderson researchers are examining whether acupuncture can prevent xerostomia in patients treated for head and neck cancer, not just treat it.
