New targeted therapies modify therapeutic strategies for advanced stage breast and tubo-ovarian cancers. Chemotherapy and endocrine therapy remain the cornerstones of breast cancer treatment. Inhibitors of CDK4/6, mTOR and PI3K are associated with endocrine therapy to increase its effectiveness. PARP inhibitors outperform chemotherapy in BRCA1/2 mutation carriers. Immunotherapy integrates into the treatment of triple-negative cancers with very promising results. For tubo-ovarian cancers, the concept of « platinum-sensitive » has been tempered since the arrival of antiangiogenic treatment and PARP inhibitors that prolong the disease control not only in patients with BRCA1/2 mutation, but also in others.
