    Abstract:
    AIM: To evaluate the prevalence and characteristics of colorectal adenoma and carcinoma in an inner city Hispanic population. METHODS: We reviewed the reports of 1628 Hispanic patients who underwent colonoscopy at Howard University from 2000 to 2010. Advanced adenoma was defined as adenoma ≥ 1 cm in size, adenomas with villous histology, high grade dysplasia and/or invasive cancer. Statistical analysis was performed using χ(2) statistics and t-test. RESULTS: The median age of the patients was 54 years, 64.2% were females. Polyps were observed in 489 (30.0%) of patients. Adenoma prevalence was 16.8% (n = 273), advanced adenoma 2.4% (n = 39), and colorectal cancer 0.4% (n = 7). Hyperplastic polyps were seen in 6.6% of the cohort (n = 107). Adenomas predominantly exhibited a proximal colonic distribution (53.7%, n = 144); while hyperplastic polyps were mostly located in the distal colon (70%, n = 75). Among 11.7% (n = 191) patients who underwent screening colonoscopy, the prevalence of colorectal lesions was 21.4% adenoma, 2.6% advanced adenoma; and 8.3% hyperplastic polyps. CONCLUSION: Our data showed low colorectal cancer prevalence among Hispanics in the Washington DC area. However, the pre-neoplastic pattern of colonic lesions in Hispanics likely points toward a shift in this population that needs to be monitored closely through large epidemiological studies.
