ABSTRACT
Introduction: Cancer is a high-impact disease, malignant tumors have positioned themselves as the leading causes of mortality for several decades, in Mexico more than 85,000 deaths occurred from this cause. Colorectal cancer is the third most frequent neoplasia and the second cause of death secondary to cancer. Objective: To know the prevalence and histopathological characteristics of colorectal carcinoma in men under 45 years of age. Material and methods: Direct research in the pathological archive of the UMAE HEP and use of the SPSS program. All men diagnosed with colorectal carcinoma under 45 years of age, diagnosed at this center, from 2014-2019 were included; Patients without a diagnosis of colorectal carcinoma or who were not part of the histopathological file were excluded. They were categorized by histological type, degree of differentiation, lymphovascular and perineural invasion, and lymph node invasion. Ethical aspects: study without risk. Results: 65,325 histopathological studies were analyzed, finding 128 patients with a diagnosis of colorectal carcinoma and a prevalence of 0.19%, 122 (95.3%) were adenocarcinomas and 6 (4.68%) squamous cell carcinomas of the anal region. Only 55 cases had a complete histopathological report, 46 (83.6%) adenocarcinomas usual or with production of mucus, 3(5.5%) adenocarcinomas with sig- net ring cells, 1(1.8%) squamous cell carcinoma of the anal region and 5(9.1%) intestinal- type adenocarcinomas of the anal region. Conclusions: An unequivocal definition of "early-onset colorectal cancer" is necessary, since there is no clear or widely accepted consensus available in the literature, our mean presentation time was 37.2 years and a prevalence of 0.19%; Also finding a correlation between lymphovascular invasion and the presence of lymph node metastases.REFERENCES
