Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are breast cancer patients diagnosed with ductal carcinoma in situ (DCIS) who are indicated for adjuvant radiation therapy.

Probably not a fit

Patients undergoing systemic oncological therapy or those not indicated for adjuvant radiation therapy will not benefit from this study.

What this trial studies

This observational study aims to identify genetic and molecular biomarkers that predict how breast cancer patients respond to radiation therapy. It involves a monocentric approach at the Institute of Oncology Ljubljana, focusing on patients with ductal carcinoma in situ (DCIS) who are receiving adjuvant radiotherapy without systemic therapy. The study will assess adverse events related to radiation treatment over a five-year follow-up period and will analyze blood samples for biomarkers before, after, and during follow-up. Informed consent will be obtained from all participants, and the study has received ethical approval.

Why it matters

Potential benefit: If successful, this study could lead to more personalized and effective radiation treatment plans for breast cancer patients.

How similar studies have gone: While there have been studies exploring biomarkers in cancer treatment, this specific approach focusing on radiation therapy response in DCIS is relatively novel.
