Clinical and histopathological features associated with high grade dysplasia and colorectal adenocarcinoma. Aim: The aim of this study is to determine the associated factors to develop high-grade dysplasia and colorectal adenocarcinoma. Methods: This is a retrospective analytical cross-sectional study, which included all the polyps found in patient’s colonoscopies between 2014 and 2015 at Instituto Nacional de Enfermedades Neoplásicas (INEN). The primary outcome was the presence of high-grade dysplasia or colorectal adenocarcinoma. Multivariate analysis was done using the Generalized Estimating Equation (GEE) to analyze variables such as size, location, age, gender, number of polyps, personal history with the primary outcome. Results were reported in prevalence ratios (PR) and 95% confidence intervals. Results: From the 2439 patients who underwent a colonoscopy between 2014 and 2015, a total of 621 polyps from 416 patients (41.3% males and 58.7% females) were included in this study. The prevalence of high-grade dysplasia and colorectal adenocarcinoma found was 47,6%. The location of the polyps was 52,5% in the left-side and 47,5% in the right-side. Multivariate analysis showed that polyp size ≥1cm (RP=5,57, IC 95%: 4,16-7,47) and left-sided polyps (RP=1,20, IC 95%: 1,01-1,41) had higher probability to develop high-grade dysplasia or colorectal adenocarcinoma. Conclusions: An increase in polyp size and left-sided lesions are associated with high-grade dysplasia or colorectal cancer.
