Treatment Delays in Colorectal Cancer More Common in Urban Men, Racial Minorities
TOPLINE:
Among patients with early-onset colorectal cancer (CRC), treatment delays exceeding 90 days were more common in all-urban populations and seemed to disproportionately affect men and Asian or Pacific Islander, Black, and Hispanic patients. Although several differences were statistically significant, the absolute differences in treatment timing were modest — for instance, the mean time to treatment was 20.7 days in all-urban areas vs 17.8 days in mostly rural areas.
METHODOLOGY:
- Adults with early-onset CRC frequently face diagnostic delays and present at an advanced stage, and this is particularly common among men and racially or ethnically minoritized groups in disadvantaged areas. However, studies evaluating how sex, race and ethnicity, and geography affect timely treatment are scarce.
- Researchers conducted a retrospective cross-sectional analysis using data from the Surveillance, Epidemiology, and End Results (SEER) Program, involving 79,090 patients with early-onset CRC between 2006 and 2020.
- Overall, 53.22% were men; 73.9% were aged 40-49 years; and 54.7% were White, 21.0% Hispanic, 13.8% Black, 9.0% Asian or Pacific Islander, and 0.6% American Indian or Alaska Native. More than half (66.5%) resided in all-urban areas, 20.6% in mostly urban areas, 7.0% in mostly rural areas, and 5.9% in all-rural areas.
- Researchers evaluated the time to treatment (defined as treatment initiation within 30, 60, or 90 days after diagnosis) and assessed its associations with sex, race, and rurality. False discovery rate (FDR) adjustment was applied to multivariable analyses to account for multiple comparisons, and FDR-adjusted two-sided P values were reported.
TAKEAWAY:
- The mean time to treatment in the overall cohort was 20.0 days; it was shortest in mostly rural areas (17.8 days) and longest in all-urban areas (20.7 days).
- Among patients in all-urban areas, men had 5% lower likelihood of initiating treatment within 90 days than women (hazard ratio [HR], 0.95; 95% CI, 0.93-0.97).
- Similarly, Asian or Pacific Islander (HR, 0.96; 95% CI, 0.93-0.99; P = .01), Black (HR, 0.95; 95% CI, 0.92-0.98; P = .001), and Hispanic (HR, 0.93; 95% CI, 0.91-0.95; P < .001) patients in all-urban areas were less likely than White patients to start treatment within 90 days. Comparable patterns were seen at the 30- and 60-day thresholds.
- In mostly rural areas, Black patients were more likely than White patients to start treatment earlier (30-day HR, 1.19; 95% CI, 1.06-1.34 and 90-day HR, 1.15; 95% CI, 1.02-1.28), whereas men were less likely than women to initiate treatment within 90 days (HR, 0.90; 95% CI, 0.85-0.96).
- Researchers found that several HRs were statistically significant but were numerically close to 1.00, indicating modest absolute differences in treatment timing.
IN PRACTICE:
“The consistency of these delays across sociodemographic groups challenges assumptions of uniformly timely access in urban settings. Overcrowded urban health care systems or inefficient public transportation may limit access to care,” the authors wrote, noting that “young adults face distinct challenges across life stages, including lack of health insurance among patients aged 18 to 29 years and financial strain among patients aged 30 to 39 years that hinder timely access to treatment.”
SOURCE:
The study, led by Meng-Han Tsai, PhD, Georgia Prevention Institute, Augusta University, Augusta, Georgia, was published online as a research letter in JAMA Network Open.
LIMITATIONS:
The study characterized time-to-treatment patterns rather than clinical outcomes and relied on SEER data without day-level treatment timing. Additionally, the observed HRs were small, but even modest delays may have led to population-level disparities.
DISCLOSURES:
This research was supported by the Augusta ROAR SCORE Career Enhancement Core through a grant awarded to Tsai. The authors declared having no relevant conflicts of interest.
