Comparing Early and Late Onset Colorectal Cancer Patients

Early-Onset Colorectal Cancer Versus Late-Onset Colorectal Cancer: a Prospective Observational Cohort Study to Explore the Clinical, Sociodemographic, Genetic, and Molecular Characteristics Associated With Adverse Oncological Outcomes (

Istituto Clinico Humanitas · NCT06326879

This study looks at the differences between younger and older patients with colorectal cancer to see why younger patients might have a tougher time after treatment.

What this trial studies

This observational study investigates the differences in clinical, socioeconomic, behavioral, genetic, and molecular factors between patients diagnosed with Early Onset Colorectal Cancer (EOCRC) before age 50 and those diagnosed with Late Onset Colorectal Cancer (LOCRC) after age 50. The study aims to validate previous findings regarding the higher recurrence rates of colorectal cancer in EOCRC patients and explore associations with various factors affecting postoperative survival. By collecting data through questionnaires and biological samples, the study seeks to provide insights into the aggressive nature of EOCRC and its underlying causes.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years old with a confirmed diagnosis of colorectal adenocarcinoma at stages I-III who are scheduled for elective curative surgery.

Not a fit: Patients with metastatic colorectal cancer or those requiring emergency or palliative procedures will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management strategies for patients with Early Onset Colorectal Cancer.

How similar studies have performed: While studies on colorectal cancer exist, this specific comparative approach focusing on early versus late onset is relatively novel and has not been extensively tested.
