QOL decreases initially after laryngectomy; some QOL areas recover slowly over the course of the year after surgery, and some remain significantly worse than at baseline.

Background. The aim of this study was to test the validity of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, Core Module (QLQ-C30) and Head and Neck Module (QLQ-H&N35) for patients who have undergone surgery due to laryngeal cancer.Methods. A total of 323 patients from 6 different centers in Germany who had been operated on completed the QLQ-C30 and the QLQ-H&N35 in addition to being surveyed in a personal interview.Results. Multitrait scaling analysis confirmed the proposed scale structure of both questionnaires. Cronbach's alpha of the QLQ-C30 scales ranged from 0.64 (Cognitive Functioning) to 0.94 (Global Health Status); the alpha of the QLQ-H&N35 ranged from 0.55 (Speech) to 0.90 (Sexuality). Known-groups comparisons showed multiple differences in sociodemographic and clinical variables.Conclusion. It can be concluded that the QLQ-H&N35, in conjunction with the QLQ-C30, is a reliable instrument that is able to differentiate between diverse groups of patients with laryngeal cancer after surgery.

Reduced libido and sexual enjoyment is a common problem after laryngeal and hypopharyngeal cancer surgery. However, it is not caused by the oncological treatment but rather by the cancer itself. Depression is often associated with sexual problems. Both should be discussed in medical consultations with head and neck cancer patients when appropriate to provide adequate treatment.

In view of the stability of psychological distress among half of the spouses within 3 years after TLE and their refusal of professional support, there is a need for the development and evaluation of new treatment strategies to help spouses cope with psychological distress. Our results indicated the most common additional professional need was learning relaxation methods, which may be used as a starting point for the investigation of new coping strategies in future studies.

Symptoms caused by disease are easier for patients to live with than more general nonspecific symptoms. Taking into account that some adverse effects of disease or therapy are partially irreversible, target values additional to changes of HRQL can be helpful when interpreting data.

Mental disorders occur in laryngectomees as frequently in men as they do in women. Total laryngectomised patients who were mentally ill did not receive enough psychotherapeutic or psychiatric support. As mental health seems to be related to successful voice restoration, future research should develop and evaluate special psychosocial supportive programmes for patients with laryngeal cancer, especially regarding alcohol dependence treatment.

The discovered limitations of QOL should be observed more closely during follow-up treatment, and patients should be informed about these potential effects before partial laryngectomy.

Subjective and objective assessment of quality of life can differ, which led to paradox results in this study, especially for voice intelligibility. This might be due to the fact that partially resected patients have higher expectations of their operation.
