Abstract

To inquiry into clinical-pathological factors influencing cytological accuracy of pancreatic head lesions. Cytology was retrospectively evaluated in 94 inpatients with a mass in head of pancreas existing with chronic pancreatitis in the past decade, the results of cytology were compared with clinical pathology or clinical follow-up to estimate the value and accuracy of cytology in detecting pancreatic cancer.

Pancreatic ductal epithelium were divided into PanIN1, PanIN2 and PanIN3 three types according to classified criterion of pancreatic intraepithelial neoplasia (PanIN). Forty-six patients were pathologically diagnosed as pancreatic cancer and five patients as chronic pancreatitis, accordingly, 29 malignant, 5 suspicious, 10 atypical hyperplasia among of them 5 malignant, 3 hyperplastic ductal epithelium, 1 nondiagnostic results due to interfered by blood and 3 insufficient specimens. 43 patients were clinically diagnosed as chronic pancreatitis. Cytologic evaluation of ...Continue Reading
