title: High efficacy of concomitant treatment of undifferentiated (anaplastic) thyroid cancer with radiation and docetaxel.
abstract: BACKGROUND
  Anaplastic thyroid carcinoma (ATC) is a rare but aggressive solid tumor with a very short survival time even with multimodality treatment. In view of in vitro data and the high rate of p53 mutations in ATC, we have used combined treatment with external beam radiation and docetaxel.
  
  
  OBJECTIVE
  The objective was to analyze the activity using radiation plus docetaxel.
  
  
  METHODS
  The design was a retrospective analysis.
  
  
  METHODS
  The study was performed in a referral center of a university hospital.
  
  
  METHODS
  A total of six patients with ATC were treated at our institution.
  
  
  METHODS
  Treatment consisted of standard external beam radiation of 60.0 Gy in 30 fractions along with docetaxel at a flat dose of 100 mg absolute every 3 wk for a total of six cycles starting within the first week of radiation.
  
  
  METHODS
  The outcome measure included clinical response and survival.
  
  
  RESULTS
  Five patients completed radiochemotherapy. One patient has completed radiation but is still on treatment with docetaxel. Four patients achieved complete remission and two partial response. During radiation therapy, four patients developed severe mucositis/stomatitis and two dermatitis, necessitating hospitalization. Two patients developed pneumonia and one urinary tract infection. All patients were hospitalized for a median of 17 d (range, 4-40 d) because of toxicites. After a median follow up of 21.5 months (range, 2-40 months), five patients are alive.
  
  
  CONCLUSIONS
  The preliminary data suggest that the combination of radiation and concomitant docetaxel is highly effective in patients with ATC. However, a formal phase II study is needed to assess the therapeutic potential of this combination.
