title: [Changes in hemoglobin concentrations in combined radio- and chemotherapy in locally advanced ORL tumors].
abstract: BACKGROUND
  Despite multimodality treatment strategies of locally advanced head and neck cancers long-term results leave much to be desired. There is evidence that oxygenation status of head and neck tumors is directly influenced by the hemoglobin concentration. The aim of this study was to verify changes in the hemoglobin level during combined radio-chemotherapy of locally advanced head and neck tumors.
  
  
  METHODS
  Sixty-eight patients with locally advanced head and neck cancer had primary or adjuvant radiotherapy with doses of 60 to 74 Gy in combination with cisplatin- (+/- 5-FU) or carboplatin chemotherapy in the first and fifth week of treatment. Hemoglobin levels were analyzed before and at the end of radiotherapy.
  
  
  RESULTS
  In 41% of all patients the initial hemoglobin concentration was below normal levels. The mean hemoglobin values in all patients dropped significantly from 12.9 +/- 1.7 g/dl before to 11.6 +/- 1.6 g/dl at the end of treatment. In 12 cases (18%) allogeneic erythrocytes had to be transfused during treatment. At the end of treatment 76% of all patients had anemic hemoglobin levels. In the groups of patients with cisplatin and carboplatin chemotherapy a significant decrease in hemoglobin levels was seen without meaningful statistical difference between these 2 groups.
  
  
  CONCLUSIONS
  In patients with locally advanced head and neck cancer a high initial rate of anemia was registered (41%): This rate was nearly doubled during chemoradiation (76%). Since several studies have shown a correlation between hemoglobin levels and local tumor control, there is evidence, that this group might benefit from correcting anemia before combined radio-chemotherapy.
