Hereditary breast ovarian cancer syndrome
MONDO:0003582An autosomal dominant inherited syndrome caused by mutations in the BRCA1 or BRCA2 genes. Patients are at high risk of developing breast cancer, particularly before the age of fifty, high risk of developing a second primary breast cancer, and high risk of developing both breast and ovarian cancer.
Also known as: BRCA1- and BRCA2-associated hereditary breast and ovarian cancer (HBOC), Hereditary Breast and Ovarian Cancer Syndrome, familial breast and ovarian cancer syndrome, familial breast/ovarian cancer (BRCA1, BRCA2), hereditary breast and ovarian cancer, hereditary breast and ovarian cancer syndrome, hereditary breast ovarian cancer syndrome, hereditary breast/ovarian cancer (BRCA1, BRCA2)
67 clinical trials for this condition and its sub-types, 35 tagged with Hereditary breast ovarian cancer syndrome itself.

New triple therapy targets hard-to-treat breast cancers
Disease control OngoingThis study tests a combination of three drugs—cisplatin, romidepsin, and nivolumab—in people with advanced triple-negative breast cancer or BRCA-related breast cancer that has spread. The goal is to see if the combination can shrink tumors and control the disease. About 51 partic…

Which surgery best prevents ovarian cancer without harming sexual health?
Prevention OngoingThis study looks at two types of surgery to prevent ovarian cancer in women aged 30-50 who have gene mutations that raise their risk. One surgery removes both the fallopian tubes and ovaries, while the other removes only the tubes first and delays removing the ovaries. The goal i…

Beyond BRCA: new gene panel could sharpen cancer risk prediction
Knowledge-focused OngoingThis study is investigating whether testing for a panel of 24 genes, in addition to the well-known BRCA1 and BRCA2 genes, can better estimate the risk of breast and ovarian cancer. Researchers will analyze genetic samples from people with a family history of these cancers, as wel…
