This study aimed to evaluate the accuracy of EUS and EUS-FNA biopsy in the diagnosis of conventional endoscopic biopsynegative diffuse or circumferential gastrointestinal lesions.
43,45-47) Carcinoembryonic antigen may have a higher sensitivity, specificity, and accuracy than cytology or EUS-FNA alone.
The final diagnoses were determined by histopathological examination of specimens obtained by surgery, EUS-FNA, or biopsy of liver metastases.
Material and Method: The EUS-FNA findings of 10 patients who had EUS examination because of mediastinal lesions between May 2008 and November 2009 in our hospital gastroenterology clinic, were retrospectively reviewed.
DNA was extracted from EUS-FNA biopsy samples with the QIAamp DNA Micro Kit (Qiagen), as previously described (14).
11) Immunohistochemical workup was performed for this EUS-FNA specimen; the tumor cells were diffusely positive for PAX8, cytokeratin 7, and c-kit/CD117 (Figure 2, C through E), which are all expected to be expressed in chromophobe renal cell carcinomas.
Methods: From March 2003 to July 2009, results of pancreatic cyst EUS-FNA in 144 patients were retrospectively evaluated.
Given the advantages of EUS-FNA, we investigated the possibility that metastatic disease could be reliably detected in MLNs of NSCLC patients by real-time RTPCR.
This low incidence of complications is along the lines reported by others and partly explains why FNA, especially EUS-FNA, has become the gold standard relative to core biopsies.
Examination of formalin-fixed, paraffin-embedded cell block materials created from the EUS-FNA traditionally contributes minimally to the cytopathologic diagnosis.
Value of EUS-FNA cytological preparations compared with cell block sections in the diagnosis of pancreatic solid tumours.
