What this trial studies

This study assesses the feasibility of using ambulatory ECG monitoring, specifically a Holter monitor, for patients undergoing treatment with 5-fluorouracil (5-FU) chemotherapy for gastrointestinal malignancies. Given the risk of cardiotoxicity associated with 5-FU, which can lead to serious cardiac events, the study aims to monitor patients in real-life conditions while they receive infusional chemotherapy at home. The goal is to gather preliminary data that could inform future studies on the relationship between 5-FU metabolism and cardiac health. By identifying asymptomatic cardiotoxicity early, the study hopes to improve patient safety and treatment outcomes.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with a diagnosis of gastrointestinal malignancy who are planned to receive FOLFOX chemotherapy.

Not a fit: Patients with pre-existing ECG abnormalities such as left bundle branch block or left ventricular hypertrophy with strain may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better monitoring of heart health in patients receiving 5-FU, potentially preventing serious cardiac events and improving treatment outcomes.

How similar studies have performed: While the approach of using Holter monitoring in this context is novel, similar studies have indicated the importance of monitoring cardiac health in patients undergoing chemotherapy.
