The goal of this observational study is to learn what are the best conditions that will give a positive outcome to men and women that receive a intra arterial therapy (IAT) for primary liver cancer. Intra arterial therapies are radiologic procedures that block liver cancer blood supply. The researchers will collect the data of participants located in the Radiology department in IRCCS Azienda Ospedaliera Universitaria Hospital in Bologna and will study clinic and radiological traits to understand which is the best case scenario for a optimal treatment response.
