Abstract
The aim of this review is attending the status and limitations of access solid tumor response criteria including the World Health Organization (WHO), the Response Evaluation Criteria in Solid Tumors (RECIST) and RECIST 1.1. This article also bring up the qualitative and quantitative methods to assessment of metabolic tumor response with 18F-FDG PET and framework for PET Response Criteria in Solid Tumors (PERCIST), version 1.0. Anatomic imaging such as WHO, RECIST and RECIST 1.1 criteria is widely used but still has limitations in response assessments. RECIST criteria may show progression of tumor more slowly than WHO criteria. RECIST 1.1 criteria result in a higher complete response rate than the original RECIST criteria at least in lymph nodes. Qualitative and quantitative approaches to 18F-FDG PET response assessment have been applied and require a consistent PET methodology to allow quantitative assessments. The more extensive the therapy, the greater the decline in SUV with most effective treatments
