Caphosol, a therapeutic option in case of cancer therapy-induced oral mucositis in children? Results from a prospective multicenter double blind randomized controlled trial

In pediatric oncology, chemotherapyor radiotherapy-induced oral mucositis (OM) is accompanied by decreased oral intake, pain, analgesics use, and hospital admission [1, 2]. Moreover, OM is correlated with an increased risk of sepsis [3, 4]. Recently, Caphosol, a supersaturated CaPO4 mouth rinse, became available to prevent or treat mucositis [5]. Papas et al. demonstrated Caphosol to have a beneficial prophylactic effect in adult hematopoietic stem cell transplantation (HSCT) patients, but evidence in pediatric patients is lacking [6]. We studied whether Caphosol can be used to treat OM in a prospective randomized study.
