Abstract

Introduction: Some studies have suggested that colorectal cancer at a younger age had distinct biological characteristics: different clinical presentations, more advanced stage at time of diagnosis and poorly differentiated carcinoma. The aim of the study is to analyze clinical and histopathological differences between younger (≤40 years of age) and older (>40 years of age) colorectal cancer patients.
Methods: A cross-sectional analysis was conducted amongst the colorectal cancer patients who visited Bir Hospital between July 2015 and April 2017. All colonoscopically diagnosed and histopathologically proven cases of colon cancer were included. Chi-square test and independent t – test was performed to analyze the difference between clinical presentations and histopathological findings among two groups of patients and p value of <0.05 was considered as significant.
Results: Thirty younger patients and thirty older patients were enrolled without any differences in gender proportion. There were no statistical differences between clinical presentation and histological grade and type in younger and older patients. The younger patients had more complaints of altered bowel habit (p <0.001) while older patients mostly presented with per rectal bleeding (p< 0.008).
Conclusions: In this study, colorectal cancer at younger ages showed similar characteristics to those of older patients except altered bowel habit was more common in younger patients while per rectal bleeding was more common in older patients. Although colorectal cancer incidence increases with age, younger patients with altered bowel habits, weight loss, anemia and anorexia should also be given due medical attention and undergo evaluation promptly.
