Experiences of colorectal cancer patients in the 2-years post-diagnosis and patient factors predicting poor outcome.

Abstract

There are few recent longitudinal studies investigating the quality of life of colorectal cancer patients in the early years following diagnosis. This study aimed to (i) compare the health status of people with colorectal cancer less than 1year from diagnosis with health status 1year later and (ii) determine the characteristics associated with a change in overall health status. The study was conducted as part of a larger trial. Participants (n = 539) were identified via the Victorian Cancer Registry in Australia, completed a computer-assisted baseline telephone interview (including the EQ-5D-3L) within 6-12months of diagnosis, and mailed a survey 12months later. At baseline, the majority of participants (55%) reported some problems, including difficulties in usual activities (26%), pain or discomfort (25%), anxiety or depression (23%) and mobility issues (15%). Sixty-nine percent had either an unchanged or increased health utility score from baseline to follow-up. The largest proportion reporting an increase in problems between baseline and follow-up related to pain or discomfort (18%). While visual analogue scale scores indicated a significantly improved health state over time overall, 32% reported a decreased health utility score from baseline to follow-up. Those aged over 80years were more likely to report a decreased health utility score compared to 60-80-year-olds. A sizeable minority of patients experience ongoing problems in their daily lives and should be offered assistance in overcoming disabilities and returning to best possible functioning, particularly older patients who appear to be vulnerable to poor outcomes.
