The aim of the present study was to investigate the association between the self-reported quality of life (QoL) versus the initial TNM stage and amount of primary and recurrent tumor therapy given in a population of formerly treated head and neck squamous cell carcinoma (HNSCC) patients. We determined QoL by the European Organization for Research and Treatment of Cancer-Quality of Life Questionnaire (EORTC-QLQ) C30/H&N35 by structured interview. One hundred and twenty-two patients less than 80 years old, who had been diagnosed with HNSCC in western Norway in the period from 1992 to1997, and who had survived until 2000, were identified. Of these patients, 106 were eligible to be included. Ninety-six of these patients agreed to be interviewed. For TNM stage as well as the type of therapy given (local surgery, neck dissection or radiation therapy), T stage predicted the general QoL scores. Both increased TNM stage and all given tumor therapy seemingly caused lower H&N symptom QoL scores. Of the various tumor treatments employed, neck radiation therapy and neck dissection were indicated to be the most closely associated with the H&N QoL scores. Having neck dissection performed seemingly caused impairment beyond what was explained by the initial TNM stage. In conclusion, tumor therapy to HNSCC should not be restricted due to general QoL considerations. Further study of how and when to perform neck treatment is suggested in order to avoid unnecessary reduced H&N QoL.
