"“In cancer patients there are two important things when evaluating a therapy: whether it extends survival and whether it improves quality of life (even if it doesn’t extend survival),” Xie explained.
Although many studies have measured progression-free survival, most have not reported on health-related quality of life. Xie and his colleagues were able to find 38 studies, including a total of 13,979 cancer patients with 12 different cancer types, that did look at both endpoints.
Data pooled from all 38 studies showed no significant association between progression-free survival and quality of life.
The researchers had difficulty comparing data from the studies because quality of life was not always measured in the same way. Xie hopes that in the future, researchers will standardize the way they measure quality of life."
