Introduction: The colorectal cancer is the most frequent neoplasm of the gastrointestinal tract and the second cause of cancer related death. Objective: To design a clinical and epidemiological profile of the colorectal cancer at the Western Region of the Paraná State from 2016 to 2018. Method: Analytical cross-sectional observational study based on the evaluation of the results of anatomopathological exams, between 2016 and 2018, at a regional specialized center. Analyses were performed using descriptive statistics, chi-square test for association and Mann-Whitney U test. A significance level of 5% was adopted. Results: The analysis of 509 positive anatomopathological reports of colorectal cancer allowed to identify the predominance of male patients and mean age at diagnosis of 62 years. The malignancy was more incident in patients between 61 and 70 years of age (29.9%). A considerable number of cases was found in patients younger than 50 years (19.6%). The disease was predominant at the left colon, of the type moderately differentiated infiltrating adenocarcinoma according to the histological classification. Association between the tumor topography and sex was found, with predominance of females for the right colon and males for the left colon (p=0.0081). Conclusion: This study designed the colorectal cancer clinical and epidemiological profile at Paraná’s Western Region. The disease affects more males, older than 60 years of age, mostly with moderately differentiated infiltrative adenocarcinoma at the left colon. These findings are relevant considering the possibility of applying international cancer screening protocols in this population.
