Acupuncture can prevent radiation-induced chronic dry mouth
Source: http://www.virtualmedicalcentre.com Author: staff When given alongside radiation therapy for head and neck cancer, acupuncture has shown for the first time to reduce the debilitating side effect of xerostomia, according to new research from The University of Texas MD Anderson Cancer Center and Fudan University Shanghai Cancer Center. The study, published in the journal Cancer, reported findings from the first randomised controlled trial of acupuncture for the prevention of xerostomia. Xerostomia, or severe dry mouth, is characterised by reduced salivary flow, which commonly affects patients receiving radiotherapy for head and neck cancer. Most current treatments are palliative and offer limited benefit, according to Lorenzo Cohen, Ph.D., professor in MD Anderson's Departments of General Oncology and Behavioral Science and director of the Integrative Medicine Program. The condition impairs quality of life for patients, as it creates difficulties eating, speaking and sleeping, while also increasing the risk for oral infections. "There have been a number of small studies examining the benefits of acupuncture after xerostomia develops, but no one previously examined if it could prevent xerostomia," said Cohen, who is also the study's principal investigator. "We found incorporating acupuncture alongside radiotherapy diminished the incidence and severity of this side effect." Cohen and his colleagues examined 86 patients with nasopharyngeal carcinoma, treated at Fudan University Shanghai Cancer Center. Forty patients were randomised to acupuncture and 46 to the standard of care. Those in the treatment arm received acupuncture therapy three times per week during the seven-week course of radiotherapy. Patients were evaluated before [...]
