Inhibitors of the PI3K/Akt and mTOR signaling pathway have recently been established as novel potent anti-cancer agents for solid and hematologic malignancies. Several pre-clinical reports have shown a good anti-tumor activity in different HCC models and first reports from clinical trials in HCC promise a good efficacy in inhibiting angiogenesis and tumor cell growth. mTOR inhibition has also been shown to enhance the activity of other cytotoxic agents.
