Detailed Description
Fluoropyrimidines (FPs) are widely used chemotherapy agents for the management of patients with colorectal, breast, upper gastrointestinal, head and neck cancers. Capecitabine is an oral prodrug of 5-fluorouracil (5FU) which is used extensively in the UK but is associated with clinically overt cardiotoxicity in up to 9% of patients. Cardiotoxicity occurs more commonly in patients with cardiovascular disease and manifests as chest pain, myocardial infarction, congestive heart failure, or sudden death with a mortality as high as 30%. In a study of continuous ECG Holter monitoring in patients receiving 5FU infusion, the majority (68%) of patients had ischaemic ECG changes and 2 patients died suddenly. We conducted a national survey of UK oncologists and 60% felt that 5FU/capecitabine cardiotoxicity was a significant problem in their clinical practice.
Hypotheses for this toxicity include ischaemia secondary to coronary artery spasm, direct endothelial cell toxicity, myocardial toxicity and interactions with the coagulation system. Studies implicate a catabolite of 5FU, in particular fluoro-alanine (FBAL). FBAL is further metabolized to fluoroacetate (FAC), a cardiac toxin that inhibits mitochondrial aconitase, resulting in cell death.
Teysuno is an oral fluoropyrimidine that has recently obtained a European licence. It is a combination of tegafur (5-FU prodrug), gimeracil (dihydropyrimidine dehydrogenase (DPD) inhibitor) and oteracil (phosphorylation inhibitor). There have been no reports of cardiac toxicity with teysuno. The incorporation of a DPD inhibitor should reduce FBAL concentrations which may prevent FP cardiotoxicity. However, this remains to be established.

- Poorly controlled angina or MI in previous 6 months
- Any psychiatric or neurological condition which is felt likely to compromise the patient's ability to give informed consent or to comply with oral medication
- Partial or complete bowel obstruction
- Pre-existing neuropathy > grade 1 if combination therapy proposed
- Patients on therapeutic anticoagulation (warfarin or LMWH).
- Patients unable to lie flat.
- Patients unable to withstand the visits and cardiovascular investigations proposed within the study.

Measure Description |
Time Frame |
---|---|---|
The primary endpoint of the study will be a difference in the duration of ST deviation pre-treatment and during treatment.
Time Frame: Pre treatment and between day 5-7
|
This will be recorded using Del Mar Reynolds Lifecard CF/Lifecard 12 recorders, which will record 12 leads over 24 hours and continuously if the storage card is changed daily.
Pre-treatment control ECGs will be recorded for 24 hours.
Continuous 12-lead monitoring shall be recorded for three days between day 5 and 7 of treatment.
