Abstract

IntroductionHealthcare related quality of life (QoL) is defined as the impact one's level of health and wellbeing has on a number of domains, including physical, mental, spiritual and social functions. Photodynamic therapy (PDT), a cancer treatment modality, is increasingly used to treat or palliate head and neck pathologies. Due to the complex nature of this area of the body, both the pathology and the treatment of it can severely affect the quality of life. Thus far, no questionnaire has been developed which focuses on quality-of-life post-PDT of head and neck pathologies. Patients and methodsWe have developed the University College London Quality of Life Questionnaire for Patients undergoing PDT in the Head and Neck, using meta-tetra(hydroxyphenyl)chlorin (mTHPC) as the photosensitiser. This was modified from the University of Washington quality of life (UW-QOL) questionnaire. Thirty-eight patients who received mTHPC-PDT for various head and neck pathologies completed the questionnaire, with a mean follow-up of 56 days. ResultsAll patients reported improved QoL following mTHPC-PDT. The main problem that was reported was post-PDT pain, which is a common side effect. Visual symptoms, breathing, speaking and swallowing problems improved significantly in the 4th week following treatment and significant improvement in activities of daily living, social life, mood and anxiety were reported in the subsequent weeks. ConclusionsmTHPC-PDT confers improvement in QoL score in selected head and neck cancer patients with figures comparable to other treatment modalities. This exploratory study demonstrated patterns of QoL outcome. Further work needs to be done for survey validation and inclusion of a larger cohort which will allow optimal sub-group analysis and help guide further interventions.
