Abstract

Objectives: Incomplete reporting of key information on patient-reported outcomes (PROs) in randomized controlled trials (RCTs) in oncology has been highlighted repeatedly as a major barrier to the use of study findings in clinical practice. We investigated whether the quality of reporting of PRO data in cancer RCTs has improved over the last 15 years. Methods: We identified all cancer RCTs with PRO endpoints conducted across the most prevalent solid tumor types worldwide published between 2004 and 2019. The quality of PRO reporting was assessed using the International Society for Quality of Life Research recommended standards, which include important aspects related to assessment methodology, statistical analyses, and interpretation of data. Results: We assessed a total of 631 cancer RCTs in breast (n = 187), lung (n = 131), prostate (n = 120), colorectal (n = 107), and gynecological (n = 86) cancer. We observed a higher adherence to the International Society for Quality of Life Research reporting criteria in the more recently published studies. In a multivariable linear regression analysis, we observed a statistically significant improvement in the quality of PRO reporting over time (P<.001), and this relationship was independent of other measured confounding factors, such as sample size and study sponsorship. Overall, the quality of PRO reporting was higher for studies published after the publication of the Consolidated Standards of Reporting Trials-PRO Extension. Conclusions: The quality of PRO reporting in cancer RCTs published in the last 15 years has improved significantly. Our findings are encouraging because better reporting of PRO results may translate into a greater impact of study findings on real-world practice.
