Researchers in China have been investigating the potential of acupuncture in relieving xerostomia (dry mouth) induced by head and neck radiation in cancer patients with nasopharyngeal carcinoma. Current standard care often offers little in relieving this simple but distressing symptom and this randomized controlled trial compared acupuncture with current treatment options.
The researchers note that xerostermia questionnaire scores for the acupuncture patients were statistically significantly lower than controls starting at 3 weeks through to 6 months. Regarding salivary flow, group differences emerged as early as 3 weeks and salivary flow rates were improved even at 6 months post treatment.
The researchers concluded acupuncture given concurrently with radiotherapy significantly reduced xerostomia and improved quality of life.
