Abstract
BACKGROUND

Cardiac toxic effect of tegafur (S-1) is extremely rare, and there has been no report on this issue so far.

CASE SUMMARY

We herein report a typical case of single S-1 administration after radical operation for colon cancer. The patient had no background or medical history of acute coronary syndrome (ACS), and only aortic and coronary atherosclerosis was revealed by computed tomography (CT) before surgery. He complained of sternum pain during the fifth cycle of S-1 treatment. Electrocardiogram (ECG) and serum cardiac marker cardiac troponin T (cTnT) strongly suggested ACS, which was possibly caused by S-1 cardiotoxicity.

CONCLUSION

Monitoring protocols based on ECG, CT, and cTnT should be performed in real time to evaluate cardiac function during S-1 administration.

Core tip: Cardiac toxic effect of tegafur (S-1) is extremely rare, and there has been no report on this issue so far. We herein report a typical case and review the literature. The case might contribute to improving our understanding of the pharmacology and mechanism of S-1 in treating colon cancer. This report also emphasizes the group of cancer patients who have already been diagnosed with cardiovascular atherosclerosis and serves as a reminder to gastroenterologists that delicate monitoring protocols should be carried out in real time to evaluate the cardiac function of S-1-onging patients.
