Quality of life measures in lung cancer.

ABSTRACT

Lung cancer is one of the leading causes of cancer death worldwide. Survival has not improved significantly in spite of newer therapies. In view of the high-symptom burden and severe morbidity, evaluation of quality of life (QOL) becomes important in these patients. Several instruments are now available for this purpose, and have demonstrated good correlation with performance status, symptoms, and survival. Quality of life assessments also help in comparing different therapeutic regimes, thus allowing selection of the appropriate modality. Problems of inconsistent interpretability and high-patient dropout rate poses a challenging problem that needs to be tackled. In spite of these drawbacks, QOL is now considered to be an essential component of lung cancer management and should be performed routinely. Such a practice will help the physician plan appropriate treatment strategies and set practical therapeutic goals.
