Background and study aims Hepatocellular carcinoma (HCC) is the most common type of liver cancer. This type of cancer starts in the liver (primary liver cancer). When other cancers spread to the liver it is known as secondary liver cancer. When possible, surgery is the main treatment because it still is the best options for treating primary and secondary liver cancer. As the liver is able to re-grow itself, surgeons are able to remove affected sections of the liver completely (liver resection). However, a certain amount of the liver must remain in order for the liver to re-grow. Patients who require a large section of their liver to be removed can undergo a portal vein embolization (PVE) which tries to get the liver to grow prior to a liver resection. A needle is placed through the skin into the liver and the blood vessel that has the largest amount of the tumour is embolized (cut off) by injecting an embolizing material (that is similar to glue). This tricks the liver into regrowing on the side without the tumour. After a few weeks, enough of the liver should have grown in order to have the surgery to remove the cancerous area. There are different types of materials that can be injected into the blood vessel to embolize it such as n-butyl-cyanoacrylate (NBCA) which is a liquid embolic material that usually is used as a tissue adhesive (glue). The aim of this study is to evaluate the efficacy of portal vein embolization (PVE) using n-butyl-cyanoacrylate (NBCA) through an ipsilateral approach as well as evaluate the accomplishment of liver surgery, patient out-come after hepatectomy and safety of the proposed PVE technique. Who can participate? Patients aged 5-75 who require a liver resection. What does the study involve? This study reviews the surgical outcomes of participants who have undergone a PVE and liver resection. After these procedures, participants are followed up with visits to the study centre every two weeks during the first month after the procedure and then every three months for the next five years. The follow up consists of scans of the liver and reviewing medical charts in order to assess how well the PVE worked in regrowing the liver and the overall health outcomes of the liver resection surgery. What are the possible benefits and risks of participating? There are no notable benefits or risks involved with participating. Where is the study run from? INCA - Brazilian National Cancer Institute (Brazil) When is the study starting and how long is it expected to run for? January 2011 to December 2016 Who is funding the study? Investigator initiated and funded Who is the main contact? Dr Jose Hugo Luz
