New Insights in Testing and Imaging Techniques for Solid Tumor Response Evaluation

Background: Evaluation of tumor burden plays central roles in cancer care. There remain several aspects of limitations of the conventional Response Evaluation Criteria in Solid Tumors (RECIST). More precise techniques with sufficient standardization and availability are needed for characterizing tumor biological features. Keywords: Response criteria, tumor markers, circulating tumor cells, circulating cell-free DNA, volume, surface area.
