Abstract

Background: Bowel dysfunction after rectal cancer surgery is common, but its effect on health-related quality of life (HRQOL) is complex. Objective measures of bowel function may not be a good representation on the actual impact on HRQOL. Therefore, the objective of this study is to determine whether there are differences between patient-reported bowel-related impairment versus a standardized measure of bowel dysfunction on HRQOL.

Methods: A prospective database starting in September 2018 of adult patients who had undergone sphincter preserving rectal cancer surgery up to October 2021 was queried. Patients were excluded if they had local recurrence, metastasis, persistent stoma, or had less than 1-year follow-up. Patients were administered the study instruments at their standard surveillance visit: patient-reported bowel-related quality of life(BQOL) impairment, HRQOL using the Short Form-36 (SF-36), and bowel dysfunction using the low anterior resection syndrome(LARS) score.

Results: Overall, 136 patients were included. There were 43% with no LARS, 22% with minor LARS, and 35% with major LARS. For the BQOL, 26% of subjects reported no impairment, 57% minor impairment, and 17% major impairment. There was a high proportion of discordance between BQOL and LARS, with 23% minor or major LARS in patients with no BQOL impairment, and 32% with no or minor LARS with major BQOL impairment. The BQOL was associated with more changes in SF-36 scores compared to the LARS score.

Conclusions: The patient-reported BQOL is likely to be a more relevant outcome of interest to patients than the objective LARS score. This has important implications for shared decision-making for rectal cancer treatments.
