Sporadic early-onset colorectal cancer is a specific sub-type of cancer: a morphological, molecular and genetics study.

ABSTRACT: Sporadic early onset colorectal carcinoma (EOCRC) which has by definition no identified hereditary predisposition is a growing problem that remains poorly understood. Molecular analysis could improve identification of distinct sub-types of colorectal cancers (CRC) with therapeutic implications and thus can help establish that sporadic EOCRC is a distinct entity. From 954 patients resected for CRC at our institution, 98 patients were selected. Patients aged 45-60 years were excluded to help define "young" and "old" groups. Thirty-nine cases of sporadic EOCRC (patients ≤ 45 years with microsatellite stable tumors) were compared to both microsatellite stable tumors from older patients (36 cases, patients>60 years) and to groups of patients with microsatellite instability. Each group was teste
