The natural course of the disease and the median survival of patients with HCC depend on the stage of the disease at the time of diagnosis. In patients with CLIP score O or Okuda stage I (see below) the median survival is in the range of 23–69 months, while in patients with CLIP score 3–5 or Okuda stage III median survival is only 1–14 months [1].
