Since 1990, the overall incidence and mortality rates of late onset colorectal cancer (LOCRC ≥50 years) have been decreasing due to improvements in access to screening and available treatment options. However, the rates for early onset CRC (EOCRC ≤ 49 years) have steadily increased in men and women. Less than 30% of LOCRC patients present with late-stage tumors (clinical stages III or IV) at the time of diagnosis compared to 70% of EOCRC patients. Despite this, the cellular and molecular mechanisms underlying the incidence and stage are unclear, as are appropriate strategies for prevention of recurrence in men and women with EOCRC. Effective prognostic markers are therefore urgently needed. To address this issue, we performed a detailed bioinformatics analysis based on Gene Expression Omnibus database (GSE39582; n=585 patients), wherein we identified 7 prognostic biomarkers for …
