This study is looking at whether a nutritional supplement called sulforaphane can help protect the heart from damage caused by doxorubicin (DOX) chemotherapy in breast cancer patients. Doxorubicin is an important cancer treatment, but it can sometimes weaken the heart. Researchers want to see if sulforaphane, which is found in broccoli sprouts, can prevent this heart damage while still allowing doxorubicin to fight cancer effectively. You might be able to join if you are an adult breast cancer patient (ages 18-89) who will be treated with a doxorubicin-containing regimen and do not have certain heart conditions. The study will measure changes in your heart function after doxorubicin treatment, with or without sulforaphane, to see if the supplement is helpful. The current status of this study is unclear.

Study design

This is an interventional study planning to enroll 70 participants. You would receive either sulforaphane or a placebo (an inactive pill) daily for 12 weeks, without knowing which one you are taking.

What's involved

You would take caplets daily for 12 weeks. Your heart function will be measured at the beginning of the study and again one year later.

Compensation

Not stated in the trial record.

Follow-up

Your heart function will be assessed at baseline and one year from the baseline assessment.
