What this trial studies

This trial aims to assess the inflammatory response of patients prior to elective colorectal cancer surgery and administer a preventive anti-inflammatory treatment to those exhibiting excessive pro-inflammatory responses. The intervention involves the use of alpha-ketoglutarate, a geroprotector supplement recognized as safe by the FDA, which may help reduce postoperative complications associated with systemic inflammatory response. By personalizing treatment based on individual inflammatory profiles, the study seeks to improve surgical outcomes and recovery for older patients undergoing colorectal surgery.

Who should consider this trial

Good fit: Ideal candidates for this study are patients aged 45 years and older who are scheduled for elective colorectal cancer surgery.

Not a fit: Patients undergoing emergency colorectal cancer surgery or those who are pregnant or cognitively impaired may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce postoperative complications and improve recovery times for patients undergoing colorectal cancer surgery.

How similar studies have performed: Other studies have shown mixed results with anti-inflammatory treatments in surgical settings, making this approach both innovative and potentially impactful.
