Radiological Response to the Locoregional Treatment in Hepatocellular Carcinoma: RECIST, mRECIST, and Others
- 104 Downloads
Hepatocellular carcinoma (HCC) is the sixth most common tumor worldwide [ 1]. Locoregional treatment choices for HCC include molecular-targeted chemotherapy, yttrium-90 radioembolization, and interventional radiological methods including transcatheter arterial chemoembolization (TACE) and radiofrequency ablation (RFA) [ 2, 3]. Imaging has a very important role in the management of HCC and the efficacy of treatment is usually monitored and evaluated radiologically. Response to therapy has been evaluated by morphologic methods using different criteria such as the World Health Organization (WHO) criteria or the Response Evaluation Criteria in Solid Tumors (RECIST) in treatment (Table 1). However, the development of advanced therapies has required novel methods for evaluating response to treatment. This need has led to development of tumor- or therapy-specific guidelines such as the modified computed tomography (CT) Response Evaluation (Choi) Criteria for gastrointestinal...
