Symptomatic Colorectal Cancer Is Associated With Stage IV Diagnosis in Two Disparate Populations.

In the United States, individuals of Black/African Ancestry (AA) have a higher incidence and mortality from colorectal cancer (CRC) compared to individuals of White/European Ancestry (EA). In order to develop an approach towards disentangling the complex effects of associated race and socioeconomic factors on CRC outcome, we have conducted a manual chart review of sporadic CRC pathological diagnoses (total n = 334) at an urban public hospital (UH) and a suburban university hospital (SH). There were significant differences between the SH and UH CRC patients with respect to Black/AA race (4.

Impact of type 2 diabetes on adenoma detection in screening colonoscopies performed in disparate populations.

Background: The Black/African Ancestry (AA) population has a higher prevalence of type 2 diabetes mellitus (T2DM) and a higher incidence and mortality rate for colorectal cancer (CRC) than all other races in the United States. T2DM has been shown to increase adenoma risk in predominantly white/European ancestry (EA) populations, but the effect of T2DM on adenoma risk in Black/AA individuals is less clear. We hypothesize that T2DM has a significant effect on adenoma risk in a predominantly Black/AA population.
