Genetic disposition increases the risk of breast cancer metastasis

For over 50 years, scientists have been on a quest to identify which malignant mutations within the tumor allow rogue cells to break away from the primary tumor and travel through the bloodstream and lymphatic system to metastasize throughout the body.

Novartis announced results from an updated analysis of the pivotal phase III NATALEE trial of Kisqali (ribociclib) that underscore the extended efficacy beyond the duration of treatment in combination with endocrine therapy. Results showed a sustained reduction in distant recurrence of 28.5% (HR=0.715; 95% CI 0.604-0.847; nominal P<0.0001), compared to ET alone, in patients with stage II and III hormone receptor-positive/human epidermal growth factor receptor 2-negative early breast cancer.
