A recent study uncovers the molecular signatures of mammographic calcifications in hormone receptor-positive, HER2-negative breast cancer. The research identifies distinct molecular traits associated with calcification status, suggesting that tumors with probably benign calcifications are linked to higher hormone receptor expression and endocrine therapy sensitivity, while tumors with calcifications of high suspicion for malignancy show genomic instability and cell cycle activity, pointing towards the effectiveness of CDK4/6 inhibitors. This molecular stratification may revolutionize precision treatment in breast cancer.
Mammographic calcifications, a common feature of breast cancer, have remained enigmatic in terms of their molecular underpinnings and clinical implications, particularly in the hormone receptor-positive, HER2-negative subtype. The heterogeneity of these calcifications and their association with treatment outcomes highlight a critical need for a comprehensive investigation into their molecular characteristics. Understanding this link is essential for developing personalized that have the potential to improve patient prognosis and .
Researchers at Fudan University Shanghai Cancer Center have made significant strides in understanding breast cancer calcifications, particularly in hormone receptor-positive, HER2-negative tumors. Their findings, in , offer new insights into the molecular profiles linked to these calcifications. Scheduled for release on April 9, 202.
