ABSTRACT
Objective To retrospectively evaluate the diagnostic accuracy of endoscopic ultrasonog raphy ( EUS) in pancreatic cancer, analyze the value of EUS in measurement of tumor diameters, TNM staging, and investigate the effectiveness of endoscopic ultrasonography-guided fine needle aspiration ( EUS-FNA). Methods All the data adopted from the patients underwent EUS in PUMC Hospital between 1997 and 2003. Eighty-eight patients with a final diagnosis of pancreatic cancer (56 is proven by surgical pathology, 10 by surgical findings and 22 by clinical diagnosis) and 47 patients with a final diagnosis of benign pancreatic disease were included and analyzed. Results The sensitivity, specificity, accuracy, positive and negative predictive values of EUS in the diagnosis of pancreatic cancer were 95. 5% , 59. 6% , 83. 0% , 81. 6% and 87. 5% respectively. Tumor diameters measured by EUS (2. 8?1. 0)cm were obviously smaller than those by surgical findings (6.5 ? 2. 9) cm. For TNM stage, compared with surgical findings, the accordance rates of EUS in T and N staging were 43. 1% and 61. 1% respectively. The accuracy of EUS-FNA in the diagnosis of pancreatic cancer was 76. 5% ( 13/17). Conclusions The sensitivity of EUS in pancreatic cancer is highest among all imaging procedures. Tumor diameters measured through EUS are smaller than those by surgery.
