One subtype of breast cancer shares many genetic features with high-grade serous ovarian cancer, a cancer that is very difficult to treat, according to researchers supported by the National Institutes of Health. The findings suggest that the two cancers are of similar molecular origin, which may facilitate the comparison of therapeutic data for subtypes of breast and ovarian cancers. The researchers, using data generated as part of The Cancer Genome Atlas (TCGA), described new insights into the four standard molecular subtypes based on a comprehensive characterization of samples from 825 breast cancer patients.
