title: Complications of systemic retinoid therapy in organ transplant recipients with squamous cell carcinoma.
abstract: BACKGROUND
  Organ transplant recipients receiving immunosuppressive medications are at increased risk of cutaneous malignancies.
  
  
  OBJECTIVE
  We sought to determine the complications associated with systemic retinoid therapy in severely affected organ transplant recipients receiving treatment before or during the course of metastatic squamous cell carcinoma.
  
  
  METHODS
  This was a collaborative retrospective study of solid organ transplant recipients treated with systemic retinoids for severe squamous cell carcinoma, with subjective analysis of complications associated with treatment.
  
  
  RESULTS
  Complications and intolerance of systemic retinoid therapy were common, necessitating discontinuation of therapy in six of eight cases.
  
  
  CONCLUSIONS
  This subset of transplant patients, severely affected by skin cancer, appeared to be less able to tolerate systemic retinoid therapy than patients in formal clinical trials. Intolerance of adverse effects in this context suggests the need for novel approaches with these challenging patients.
