title: Assessing the effectiveness of Dead Sea products as prophylactic agents for acute radiochemotherapy-induced skin and mucosal toxicity in patients with head and neck cancers: a phase 2 study.
abstract: BACKGROUND
  Mucositis and dermatitis are frequently encountered in patients treated with radiochemotherapy. Dead Sea products that contain minerals and other properties have proven effective in treating various skin diseases.
  
  
  OBJECTIVE
  To evaluate the effectiveness of Dead Sea products in reducing acute radiochemotherapy-induced side effects in patients with head and neck cancer.
  
  
  METHODS
  In this phase 2 study we compared the outcomes in 24 treated patients and 30 conventionally treated patients matched for age, tumor site, and type of treatment. The Dead Sea products comprised a mouthwash solution (Lenom) and a skin cream (Solaris) used three times daily for 1 week before, during, and up to 2 weeks after completion of radiotherapy. Mucositis and dermatitis were evaluated using common toxicity criteria.
  
  
  RESULTS
  Thirteen treated patients (54%) had grade 1-2 and none had 3-4 mucositis, while 17 controls (57%) had grade 1-2 and 4 (13%) had grade 3-4 mucositis. Thirteen treated patients (54%) had grade 1-2 dermatitis; there was no instance of grade 3-4 dermatitis, while 11 patients in the control group (37%) had grade 1-2 and 5 (17%) had grade 3-4 dermatitis. More patients in the control arm needed a break than did patients in the treatment the control arm needed a break than did patients in the treatment arm (P = 0.034).
  
  
  CONCLUSIONS
  The two Dead Sea products tested decreased skin and mucosal toxicity in head and neck cancer patients receiving radiochemotherapy.
