Abstract 3471: Predictors of cancer related distress among patients with colorectal cancer

Abstract

Abstract Background: Colorectal cancer (CRC) incidence among patients under age 50 has increased drastically over the past few decades. Given that increased cancer-related distress is associated with worse oncologic outcomes, studies are needed to assess the psychosocial wellbeing of CRC survivors across the shifting demographic and socioeconomic landscape. Methods: The ColoCare Study is a prospective cohort study of newly-diagnosed CRC patients enrolled across six US and European sites. We analyzed ColoCare data from the Washington University site, which has high accrual of Non-Hispanic Black (NHB) patients. Cancer-related distress was measured using a validated Cancer and Treatment Distress (CTXD) tool with 4-point Likert scales ranging from 0-3 with higher scores indicating greater distress. Covariate-adjusted linear regression analyses were used to evaluate sociodemographic, lifestyle, and clinical factors as predictors of cancer-related distress 12 months following CRC diagnosis. Results: This analysis included 156 participants enrolled from April 2017 to September 2022 who completed a 12-month CTXD questionnaire: 51.4% male; mean age 55.3 (SD 13.1) years; 64.8% Non-Hispanic White; 33.1% NHB; mean 12-month CTXD score 0.75 (SD 0.70). In covariate-adjusted models, predictors of increased distress at 12 months (Table 1) included recurrence or new metastasis (regression coefficient (β)=0.63, 95% confidence interval (CI)=0.35-0.91), stage II ((β=0.49, 95% CI=0.15-0.84) or stage III (β=0.37, 95% CI=0.02-0.72) disease, current smoking (β=0.33, 95% CI=0.10-0.56), female gender (β=0.22, 95% CI=0.00-0.44) and age (β= -0.01, 95% CI -0.02-0.00). Race and social vulnerability index were not predictors of distress in this analysis. Conclusion: Among CRC survivors, those with younger age, female gender, active smoking, advanced stage, and disease progression may benefit from targeted cancer-related distress assessment and interventions.
