This systematic review examines the effectiveness and risks of water therapy for cancer patients. The results indicate that water therapy can improve quality of life and alleviate symptoms such as lymphedema, neck and shoulder pain, fatigue, and BMI. However, due to the heterogeneity of the included studies and methodological limitations, a clear conclusion regarding the effectiveness of water therapy for cancer patients cannot be drawn.
Background Water therapies as hydrotherapy, balneotherapy or aqua therapy are often used in the relief of disease- and treatment-associated symptoms of cancer patients. Yet, a systematic review for the evidence of water therapy including all cancer entities has not been conducted to date. Purpose Oncological patients often suffer from symptoms which in patients with other diseases are successfully treated with water therapy. We want to gather more information about the benefits and risks of water therapy for cancer patients. Method In May 2020, a systematic search was conducted searching five electronic databases (Embase, Cochrane, PsychInfo, CINAHL and PubMed) to find studies concerning the use, effectiveness and potential harm of water therapy on cancer patients. Results Of 3165 search results, 10 publications concerning 12 studies with 430 patients were included in this systematic review. The patients treated with water therapy were mainly diagnosed with breast cancer. The therapy concepts included aqua lymphatic therapy, aquatic exercises, foot bathes and whole-body bathes. Outcomes were state of lymphedema, quality of life, fatigue, BMI, vital parameters, anxiety and pain. The quality of the studies was assessed with the AMSTAR2-instrument, the SIGN-checklist and the IHE-Instruments. The studies had moderate quality and reported heterogeneous results. Some studies reported significantly improved quality of life, extent of lymphedema, neck and shoulder pain, fatigue and BMI while other studies did not find any changes concerning these endpoints. Conclusion Due to the very heterogeneous results and methodical limitations of the included studies, a clear statement regarding the effectiveness of water therapy on cancer patients is not possible.
