Popis: | Lay abstract Alpha-fetoprotein (AFP) is a plasma protein commonly used as a tumor marker for hepatocellular carcinoma. Sorafenib is a targeted therapy used to block the growth of cancer cells in several ways. It affects various proteins on the surface of cancer cells as well as targets inside the cell. Some of these targets are involved in tumor angiogenesis (growth of new blood vessels). In the present analysis, elevated AFP plasma levels before starting sorafenib therapy were correlated with inferior survival compared with patients with low AFP levels, thus suggesting a possible role of AFP in resistance to sorafenib therapy. Using a specific antibody, the authors also studied the expression on cancer cells of VEGFR2, which is a protein involved in angiogenesis and one of the targets of sorafenib. No correlation was found between AFP level and VEGFR2 expression. The underlying mechanisms involved in resistance to sorafenib therapy still need to be clarified and deserve further studies. |
