Abstract
There are 2 main reasons why oncologists may require additional tissue and a histologic section in addition to cytopathology from FNA specimens: improved diagnostic accuracy and molecular characterization of tumors. Rather than mutually exclusive diagnostic procedures, EUS-FNA and EUS-CNB must be viewed as supplementary techniques and both approaches should be incorporated as essential tools in the current endoscopic armamentarium.
