Abstract
Purpose This study is an update of a systematic review of health-related quality-of-life (HRQOL) methodology reporting in non–small-cell lung cancer (NSCLC) randomized controlled trials (RCTs). The objective was to evaluate HRQOL methodology reporting over the last decade and its benefit for clinical decision making. Methods A MEDLINE systematic literature review was performed. Eligible RCTs implemented patient-reported HRQOL assessments and regular oncology treatments for newly diagnosed adult patients with NSCLC. Included studies were published in English from August 2002 to July 2010. Two independent reviewers evaluated all included RCTs. Results Fifty-three RCTs were assessed. Of the 53 RCTs, 81% reported that there was no significant difference in overall survival (OS). However, 50% of RCTs that were unable to find OS differences reported a significant difference in HRQOL scores. The quality of HRQOL reporting has improved; both reporting of clinically significant differences and statistical testing ...Keywords
