Summary
Brief summary (as posted)
The purpose of this study is to identify the genetic variants that are associated with higher risk of doxorubicin-induced cardiotoxicity can contribute towards developing a predictive algorithm comprising both clinical and genetic factors to select patients who should avoid treatment with anthracyclines. Hypothesis of this study is certain functional variants in genes that encode for metabolizing enzymes and/or targets in the doxorubicin pharmacology pathway may increase the risk of doxorubicin-induced cardiomyopathy

- label
- Breast cancer,Doxorubicin
- description
- Breast cancer patients who received at least one cycle of doxorubicin-containing adjuvant chemotherapy for treatment of early stage breast cancer at least 12 months ago and who had a pre-doxorubicin echocardiography done at NUHS will be enrolled. Study subjects will donate one sample of blood (20ml) for genetic and biomarker studies related to breast cancer and anthracyclines pharmacodynamics. An echocardiography will be performed to measure left ventricular ejection fraction, and compared with the subject's pre-doxorubicin echocardiography done at NUH. Correlative analysis will be performed between genetic variants and left ventricular ejection change.
