Mucositis is a serious side effect of cancer therapy. It is defined as inflammatory and/or ulcerative lesions of the oral and/or gastrointestinal tract. Oral mucositis is a serious and acute side-effect for patients undergoing cancer therapy (chemotherapy and/or radiotherapy).
There are approximatively 500 000 new cases per year. It is more frequent for patients with ENT cancers and leukemia. It may trigger modifications of treatment or therapy discontinuation, thus reducing the chance of recovery from cancer. It can also require enteral or parenteral nutrition with an impact on patient’s quality of life.
Photobiomodulation is recommended since 2014 as a preventive and curative treatment option for oral mucositis by the Multinational Association of Supportive Care in Cancer (MASCC).
