Breast cancer is one of the most common malignancies in women. The PI3K/Akt/mTOR signaling pathway plays an important role in several cellular processes involved in proliferation, metabolism, cell growth, and survival. Alterations in this signaling pathway have been found in a variety of tumors, including breast cancer. Constitutive activation of the PI3K/Akt/mTOR signaling pathway plays a key role in tumor pathogenesis and resistance to conventional therapy. In connection with the newly approved treatment with PI3K inhibitors, the determination of PIK3CA mutation status as a predictive marker is also gaining in importance.
