title: Effect of prophylactic fluconazole on oral mucositis and candidiasis during radiation therapy for head-and-neck cancer.
abstract: OBJECTIVE
  Radiation therapy (RT) or chemoradiation therapy (CRT) for carcinoma of the head and neck can result in high rates of candidiasis and mucositis. Prophylactic fluconazole (FCZ) has been shown to reduce the incidence of candidiasis. We report our outcomes of patients with head-and-neck cancer undergoing CRT treated prophylactically with FCZ.
  
  
  METHODS
  An institutional review board-approved database of head-and-neck cancer patients treated with RT or CRT was reviewed to identify patients treated between 2004 and 2009 who received at least 50 Gy to approximately two-thirds of the oral cavity or oropharynx mucosa. Eligible patients were divided into 2 groups: the usual care group and the prophylaxis group. The primary endpoints were the incidence of mucositis and candidiasis.
  
  
  RESULTS
  A total of 181 patients were eligible for analysis: 72 patients in the prophylactic group and 109 patients in the usual care group. Patient characteristics and radiation dose were comparable between groups. RT alone was given in 28 patients (16%). Mucositis data were available in 161 (89%) patients. Grade 2 or higher mucositis was seen in 131 (81%) patients. Prophylactic FCZ had significantly decreased grade 2 or higher mucositis. In the usual care group and prophylaxis group patients, 83 of 93 patients (89.3%) and 48 of 68 patients (70.6%), respectively, developed grade 2 or higher mucositis (P = .003).
  
  
  CONCLUSIONS
  Prophylactic administration of FCZ twice weekly during CRT for head-and-neck cancer reduces incidence of mucositis and thrush.
