title: Quality of life research in neuro-oncology: a quantitative comparison.
abstract: Our understanding of the biology of neuro-oncologic disease has improved vastly over time, however overall patient survival remains relatively poor. Our goal as clinicians, therefore, should be to ensure that the quality of life (QOL) in that survival time is optimized. Here we review neuro-oncology QOL abstracts presented at major oncology conferences and the published literature to make a quantitative comparison to other common cancer subtypes. First, all abstracts presented at major oncology meetings from 2008 to 2012 were reviewed and filtered to find those related to QOL in CNS, breast, lung, and prostate cancer. Next, a Medline search was performed to identify all QOL papers published from 2003 to 2012 for the same cancer subtypes. The results were compared as absolute values and percentages. The average percentage of CNS QOL-related abstracts presented at ASCO and ASTRO over the last 5 years was 4.9 %, compared to 6.4 % for breast, 4.4 % for lung, and 6.1 % for prostate. There is a significant difference in total percentage of QOL abstracts over the time period when comparing CNS to breast and prostate, but not lung (p < 0.05). The Medline search revealed an average of 25.2 publications per year for CNS cancer, compared to 146.2 for breast, 39.3 for lung, and 64.2 for prostate. When looking at trends over time, publications in CNS cancer have not been as prolific and have not increased as rapidly as publications in breast and lung cancer, indicating that QOL is underrepresented in neuro-oncology research. We need to improve this by standardizing QOL measures and including them in every outcome study.
