Evaluating the longitudinal effect of colorectal surgery on health-related quality of life in patients with colorectal cancer

Background and Objectives Surgery for colorectal cancer (CRC) negatively affects health-related quality of life (HRQoL). Addressing shortcomings in literature, the purpose of this study was to evaluate the impact of surgery for CRC on the course of HRQoL from baseline up to 2 years after diagnosis. Methods In this prospective, population-based study patients with newly diagnosed CRC were included between 2016 and 2019. HRQoL was assessed by the EORTC QLQ-C30 questionnaire over time both between and within subgroups of patients that underwent right-sided colonic, left-sided colonic, and rectal resection using linear mixed model analyses. Results The study included 415 patients of whom 148 patients underwent right-sided colonic (36%), 147 left-sided colonic (35%), and 120 rectal resection (29%). Overall, HRQoL scores restored to baseline level 1 year after diagnosis. Impact of surgery seems to be more prominent in patients who underwent rectal resection, as they experienced more pain and had worse role and social functioning scores 4 weeks after surgery. Finally, among patients who underwent left-sided and rectal resection, physical functioning did not return to baseline level during follow-up. Conclusion This study shows several differences (between-group and within-group) in HRQoL according to surgery type and offers perspective which patients may need additional support in the care pathway.

Automated summary

Surgery for colorectal cancer has a negative impact on health-related quality of life. This study found differences in HRQoL depending on the type of surgery, with rectal resection patients experiencing more pain and decreased role and social functioning scores 4 weeks post-surgery. Physical functioning did not return to baseline level during follow-up for patients who underwent left-sided and rectal resection.
