title: Narrow-band UVB phototherapy for management of oral chronic graft-versus-host disease.
abstract: OBJECTIVE
  Oral chronic graft-versus-host disease (cGVHD) is a debilitating complication following allogeneic hematopoietic cell transplantation. The objective of this study was to evaluate the safety and efficacy of intraoral narrow-band ultraviolet B (NB-UVB) phototherapy in the management of oral cGVHD.
  
  
  METHODS
  Patients with oral cGVHD were treated using a custom NB-UVB unit for a course of 24 phototherapy sessions. Treatments were initiated at 50 mJ/cm(2) and increased by 10% at each visit unless toxicity was noted. Toxicity and response were assessed weekly.
  
  
  RESULTS
  Eleven patients received a median of 22 (range 4-39) NB-UVB treatments; 5 patients completed 24 treatments and elected to receive a median of 7 additional treatments. Median symptom scores (0-10) for sensitivity, pain, and dryness at baseline/end of therapy were 7.5, 3, 1, and 3, 1, 2, respectively. Taking into account all patient-reported outcomes, 7/11 patients had improvement and 2/11 worsened. At least partial improvement was reported in 8/11 patients with none reporting worsening. Overtreatment occurred in 10/11 patients with all graded mild or moderate and resolving in 1-2 days.
  
  
  CONCLUSIONS
  Intraoral NB-UVB may be effective for management of refractory oral cGVHD. Further optimization of treatment parameters, as well as minimal erythema dose testing, and inclusion of a control arm are necessary in the consideration of future studies.
