BRCA study aims to unlock cancer secrets
NCT ID NCT01034033
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study collects tumor and blood samples from 3,300 people at high genetic risk for breast, ovarian, and related cancers. Researchers want to learn how these cancers develop and how well treatments work. Participants include those with BRCA1/2 or other gene mutations, or a strong family history of these cancers.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this research could improve understanding of how these cancers develop and help identify better treatments for people with BRCA mutations.
- What could go wrong
- This is an observational study, not a treatment trial. It may not directly lead to new therapies, and results depend on long-term data collection.
This is an AI summary of the original study and may miss details. Read our disclaimer.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: I. Women who have a high risk of developing breast or ovarian cancer due to a known germline mutation in the BRCA1/2, PTEN, CDH1, or TP53 cancer susceptibility genes, or due to strong family history of either breast or ovarian cancer, in the absence of known cancer susceptibility gene mutation. II. Women who are approaching surgery for resection of a pelvic mass, which is considered suspicious for neoplasia by radiologic or clinical criteria; such women may or may not also meet criteria for inclusion in group I.
