Abstract

Background Societal preference-weighted health-related quality of life (HRQOL) scores enable comparing multi-dimensional health states across diseases and treatments for research and policy.

Objective To assess the effects of living with a permanent intestinal stoma, compared to a major bowel resection, among colorectal cancer (CRC) survivors.

Research Design Cross-sectional multivariate linear regression analysis to explain preference-weighted HRQOL scores.

Subjects Six-hundred-forty CRC survivors (≥5 years) from three group-model HMOs; ostomates and non-ostomates with colorectal resections for CRC were matched on gender, age (±5 years), time since diagnosis, and tumor site (rectum vs. colon).

Measures SF-6D scoring system applied to Medical Outcomes Study Short Form-36 version 2 (SF-36v2); City of Hope Quality of Life-Ostomy (mCOH-QOL-O); Charlson-Deyo comorbidity index.

Methods Survey of CRC survivors linked to respondents’ clinical data extracted from HMO files.

Results Response rate was 52%. Ostomates and non-ostomates had similar sociodemographic characteristics. Mean SF-6D score was 0.69 for ostomates, compared to 0.73 for non-ostomates (p <.001), but other factors explained this difference. Complications of initial cancer surgery, and prior-year comorbidity burden and hospital use were negatively associated with SF-6D scores, while household income was positively associated.

Conclusions CRC survivors’ SF-6D scores were not associated with living with a permanent ostomy after other factors were taken into account. Surgical complications, comorbidities, and metastatic disease lowered the preference-weighted HRQOL of CRC survivors with and without ostomies. Further research to understand and reduce late complications from CRC surgeries as well as associated depression is warranted.
