Abstract

MURAD-REGADAS, Sthela Maria et al. Is prevalence of colorectal polyps higher in patients with family history of colorectal cancer?. J. Coloproctol. (Rio J.) [online]. 2015, vol.35, n.3, pp.146-150. ISSN 2317-6423.  https://doi.org/10.1016/j.jcol.2015.02.010.

Objectives:

To assess the prevalence of polyps in patients with a family history of colorectal cancer, in comparison to asymptomatic individuals with indication for screening.

Methods:

A prospective study in a group of patients who underwent colonoscopy between 2012 and 2014. Patients were divided into two groups: Group I: no family history of colorectal cancer, and Group II: with a family history in first-degree relatives. Demographic characteristics, findings on colonoscopy, presence, location and histological type of polyps were evaluated, comparing the two groups.

Results:

214 patients were evaluated: 162 in Group I and 52 in Group II. The distribution of patients with polyps was similar in relation to gender: polyps were evidenced in Group I in 33 (20%) female patients vs. 10 (6%) male patients (p= 1.00); in Group II, the presence of polyps was evidenced in 9 (17%) female patients vs. 2 (4%) male patients (p= 1.00). Polypoid lesions were found in 54 patients (25%), with 43 (26%) in Group I and 11 (21%) in Group II. The prevalence of adenomas was similar in both groups (Group I = 18/37% vs. Group II = 10/50%) (p= 0.83).

Conclusion:

In this preliminary study, no correlation was found between prevalence of polyps and a family history of colorectal cancer.
