The Role of Liver Biopsy in Hepatocellular Carcinoma.

RF We are closer than we have ever been before. There has been a lot of molecular work done in hepatocellular carcinoma (HCC) that has identified important pathways and targets for therapy. However, we still have not seen these targets validated the way they have been in other types of cancer. In breast cancer, for example, human epidermal growth factor receptor 2 (HER2) or estrogen and progesterone receptors can be used to make treatment decisions based on drugs targeting those pathways. In HCC, we have seen a number of treatment failures in clinical development, which is spurring researchers to look back more closely and try to get the right drugs to the right patients, based on specific biomarkers. There are several studies currently being conducted that address this therapeutic approach.
