KARMA Kontrast - a Controlled Clinical Trial Evaluating Contrast Enhanced Mammography in Early Detection of Breast Cancer

Not applicable Interventional Karolinska Institutet · NCT04579107

This study is testing a new type of breast imaging called Contrast Enhanced Mammography to see if it can help women who have been called back for suspected breast cancer get better and more accurate results compared to standard methods.

What this trial studies

This study invites women who are part of the National Mammography Screening Program and have been recalled due to suspected breast cancer to participate in an evaluation of Contrast Enhanced Mammography. The study will compare the findings from this advanced imaging technique with standard care procedures, using two blinded radiologists to assess the results independently. Additionally, the study will evaluate potential side effects and the overall patient experience with the new imaging method.

Who should consider this trial

Good fit: Ideal candidates are women aged 25 to 85 who have been recalled for further investigation after abnormal mammographic findings.

Not a fit: Patients with a history of breast cancer, recent breast biopsies, or certain medical conditions such as renal failure or iodine contrast allergies may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve early detection rates of breast cancer, leading to better patient outcomes.

How similar studies have performed: Other studies have shown promise in using advanced imaging techniques for breast cancer detection, suggesting that this approach may yield beneficial results.
