Utility of prognostic factors in the detection of pre-neoplastic colon lesions

Abstract

INTRODUCTION: Colorectal cancer (RCC) is an important health problem worldwide. The goal of
screening programs is to make early diagnosis and reduces mortality.
Colonoscopy is a key tool for stratifying the patients and offer timely surveillance.
OBJECTIVES: To determine the prevalence of adenomas diagnosed during all colonoscopy performed
over a period of 5 years.
To establish associated risk factors.
To stratify patients risk according to the clinical history and their correlation with the pathological findings.
PATIENTS AND METHODS: This is an observational, retrospective, analytical study. Inclusion criteria:
patients over 18 years of age who underwent a colonoscopy for a period of 5 years. Demographic variables
and anatomo-pathological result of the polyps were analyzed. Statistical analysis: The characteristics of the
simple were analyzed with descriptive statistics. To determine the relationship of different risk factors with
the type of polyp obtained, a univariate analysis was performed; Chi Square test for categorical variables
and Student's T test for continuous variables.
RESULTS: The prevalence of adenomas was 26%. The detection of polyps during SCCR colonoscopies
was associated with male sex (p = 0.44), andolder than 50 years (p = 0.001). Belonging to a specific risk
group did not influence the diagnosis of adenomas (p = 0.156).
CONCLUSION: The prevalence of polyps was similar to that reported by other studies. We found an
association between demographic factors (male sex and age) and the detection of polyps during an SCCR
program.Belonging to a specific risk group did not influence the diagnosis of adenomas.
