title: [Recall dermatitis caused by re-exposure to docetaxel following irradiation of the brain. Case report and review of the literature].
abstract: BACKGROUND
  Together with radiation therapy the taxanes Paclitaxel and Docetaxel are more and more integrated into multimodal therapy regimens concerning breast- and lung cancer as well as squamous cell carcinoma of the head and neck. Especially in palliative situations we have to be aware of increasing side effects caused by interaction of the different treatment components. Therefore we report on a severe recall dermatitis that occurred in two breast-cancer patients following irradiation of the brain and reexposition to Docetaxel.
  
  
  METHODS
  From January until March 1999 two female patients suffering from metastatic breast cancer and newly diagnosed cerebral metastases respectively carcinomatous meningitis underwent irradiation of the whole brain (2 Gy 5 days/week up to a reference dose of 50 Gy) in our department. Both patients had several courses of Docetaxel (Taxotere) 30 mg/m2 BSA weekly respectively 100 mg/m2 BSA/month since October and November 1998. After completion of radiotherapy chemotherapy with Docetaxel was continued.
  
  
  RESULTS
  Both patients tolerated Docetaxel well before and during radiotherapy. However, after having finished irradiation of the brain and receiving Docetaxel again a severe erythema of the irradiated skin and large areas of moist epitheliolysis with crust occurred (CTC grade IV).
  
  
  CONCLUSIONS
  The dermatitis related to irradiation and reexposition to Docetaxel observed in our two cases is interpreted as a recall reaction. The basic initiating pathologic mechanism has not been solved completely. Further investigation is needed to find out how the taxanes can be used in combination radiochemotherapy regimens without causing severe toxicity to the irradiated skin or mucosa.
