摘要

Purpose

The purpose of this study was to examine factors affecting health-related quality of life (HRQOL) over time in older adult survivors of colorectal cancer (CRC) and determine demographic and clinical characteristics associated with declines in HRQOL.

Methods

This secondary analysis utilized the Surveillance Epidemiology and End Results and Medicare Health Outcomes Survey and included CRC survivors aged 65 or older who completed at least one survey pre-diagnosis and two surveys within ten years post-diagnosis. HRQOL was captured by the Veterans Rand 12-item scale which provides mental and physical composite scores. Group-based trajectory modeling was employed to identify HRQOL trajectories. Multinomial logistic regression predicted group membership based on demographic and clinical characteristics.

Results

The cohort (n = 649) was predominantly female (58%), white (70%), with an average age of 77 years. Most participants were diagnosed at Stage I disease (56%) and underwent surgery (63%). Three groups were identified based on trajectories of MCS: low increasing, medium decreasing, and high stable. Income and comorbidity number predicted MCS group membership. Five groups were identified based on trajectories of PCS: low decreasing, medium stable, steeply decreasing, high decreasing, and high stable. Older age at diagnosis, identifying as Hispanic, and comorbidity number predicted PCS group membership.

Conclusions

Comorbidities, age at diagnosis, ethnicity, and income significantly impact the HRQOL of older adult survivors of CRC. The resources and needs of each patient should be considered in long-term survivorship plans.
