Clinical Trial Summary

Observational prospective cohort study designed to assess the mechanisms of fluoropyrimidine induced cardiovascular toxicity.

Description:

Fluoropyrimidine (5-FU and Capecitabine) based chemotherapy regimens form the cornerstone of treatments for gastrointestinal (GI) cancers. Fluoropyrimidines however, are associated with the development of cardiovascular toxicity which can take on different forms including chest pain, myocardial infarction, arrhythmias, heart failure and sudden death. The underlying mechanisms of cardiovascular toxicity are not fully understood.

The investigators will use quantitative cardiovascular magnetic resonance perfusion imaging, CT coronary angiography, extra-cardiac vascular assessments and serum cardiac biomarkers to improve insights into the pathophysiology of fluoropyrimidine cardiotoxicity. All enrolled participants in this two centre study will have GI cancers requiring treatment with fluoropyrimidine chemotherapy.

Intervention

Diagnostic Test:
• Cardiovascular magnetic resonance with stress perfusion
Cardiac MRI scan to assess changes in left ventricular function, parametric mapping, strain and myocardial blood flow. In cohort 1 this will be performed pre, during and on completion of treatment. In cohort 2 this will be performed during the acute presentation and on completion of treatment.
• CT coronary angiography
CT coronary angiogram at baseline only in both cohorts to assess for coronary artery disease
• Retinal OCT angiography
Retinal OCTa to assess changes in retinal vasculature. In cohort 1 this will be performed pre, during and on completion of treatment. In cohort 2 this will be performed during the acute presentation and on completion of treatment.
• Sublingual microscopy (GlycoCheck)
To determine changes in sublingual microvascular health. In cohort 1 this will be performed pre, during and on completion of treatment. In cohort 2 this will be performed during the acute presentation and on completion of treatment.
• Serum cardiac biomarkers (High sensitivity troponin, NT pro BNP)
Performed to assess for myocardial injury. In cohort 1 this will be performed pre, during and on completion of treatment. In cohort 2 this will be performed during the acute presentation and on completion of treatment.
