Purpose
Colorectal cancer (CRC) is the third most common cancer in the USA. The objective of this study was to compare quality of life (QoL) across long-term colorectal cancer survivors and unaffected matched controls while adjusting for comorbidities.
Methods
The National Cancer Institute (NCI)-funded Colon Cancer Family Registry (CCFR) was used to randomly select and recruit CRC survivors (≥ 5 years from diagnosis) and matched controls for a cross-sectional survey. Nine geographically diverse sites in the USA from the CCFR participated in the study. Telephone interviews were conducted using computer-assisted methods to assess QoL.
Results
A total of 403 cases and 401 controls were included in the final sample. Unadjusted comparison revealed no significant difference between CRC survivors and controls with respect to measures of fatigue, social, emotional, functional, and physical well-being. Multivariate logistic regression revealed that case status had a significant negative influence on colorectal cancer-specific QoL measures. Higher comorbidity indices had a significant negative influence on overall QoL regardless of case status.
Conclusions
Quality of life among long-term CRC survivors is similar to control subjects, with the exception of worse CRC-specific QoL measures. Higher comorbidity indices were independently associated with poor QoL for both cases and controls.
Implications for Cancer Survivors
Survivors and healthcare providers should be aware that long-term QoL is comparable to the general population; however, there is potential that digestive tract-specific issues may persist.
