Outcome of endobronchial electrocautery versus external beam radiotherapy or both together in the palliative management of non-small cell lung cancer

Systematic literature review of health-related quality of life in locally-advanced non-small cell lung cancer: Has it yet become state-of-the-art?

Lung cancer and its treatment have an important impact on the patients' health-related quality-of-life (HRQoL). A systematic literature review of prospective clinical studies published since 2005 and measuring HRQoL in patients with locally-advanced non-small cell lung cancer (LA- NSCLC) was performed. Besides reviewing the HRQoL impact of LA-NSCLC treatment, it critically examined the frequency, methodology and quality of HRQoL data collection and analysis in LA-NSCLC clinical studies. Out of 814 potentially eligible publications, only 27 (representing 19 individual studies) met the inclusion criteria. Eight studies documented an impact on HRQoL. Large variability in use of HRQoL instruments, statistical analysis and methodological quality was observed. Reporting of HRQoL data lacks standardization, but recent initiatives establishing recommendations to standardize the analysis and reporting of HRQoL in cancer trials are expected to address these issues. Overall, more research is needed to evaluate the treatment impact on HRQoL in both clinical trials and daily care.
