Placebo-Controlled Phase II Randomized Clinical Trial of Photobiomodulation Therapy in Head and Neck Cancer Survivors With Chronic Lymphedema
The U.S. Food and Drug Administration approved photobiomodulation therapy (PBMT) as a treatment for breast cancer-related arm lymphedema (BCRL) in 2006. The investigators conducted two pilot clinical trials. Results demonstrated the feasibility, acceptability, and preliminary efficacy of PBMT for the treatment of chronic lymphedema in head and neck cancer (HNC) survivors. The objective of this study is to further investigate and confirm the positive effects of PBMT on HNC-related chronic lymphedema.
• \>18 years of age Biopsy proven head and neck cancer No evidence of cancer at the time of study enrollment, between 12- and 60-month post-cancer treatment Chronic lymphedema (defined as lymphedema persisting for a minimum of 6 months) A minimum of 2 sites of external lymphedema At least 1 site with lymphedema of moderate severity as assessed using the HN-LEF Assessment Criteria Failed lymphedema therapy (defined as any of the following: incomplete response to therapy, progression of lymphedema after therapy, inability to perform effective self-care resulting in fluid re-accumulation; and inability to complete treatment due to systems barriers). In addition, patients must be able to understand English in order to complete questionnaires; and to provide informed consent.
