๐ Clinicopathological Insights into Early vs Later-Onset Colorectal Neoplasia
Colorectal neoplasia, a significant contributor to global cancer burden, is increasingly being diagnosed in younger populations ๐งฌ. This study explores the clinicopathological distinctions between early-onset (≤50 years) and later-onset (>50 years) colorectal neoplasia, particularly focusing on lesions removed through endoscopic techniques ๐ฌ. ๐ 1. Epidemiological Landscape Early-onset colorectal neoplasia is witnessing a concerning rise ๐, often linked to lifestyle factors such as diet ๐, sedentary habits ๐ช, and genetic predisposition ๐งฌ. In contrast, later-onset cases are traditionally associated with cumulative environmental exposure and aging-related mutations ⏳. ๐งซ 2. Histopathological Characteristics Early-onset lesions frequently exhibit poor differentiation , mucinous features, and signet-ring cell morphology ๐งช. These aggressive histological patterns may indicate a more rapid disease progression ๐. Later-onset neoplasms, however, often show well to modera...
