BACKGROUND/AIMS: Early and accurate diagnosis of cystic neoplasm of the pancreas is difficult especially for the differentiation of benign or malignancy. In this study, we try to compare EUS-guided fine needle aspiration biopsy combined with measurement of the cyst fluid and serum levels of CEA, and CA19-9 for the preoperative diagnosis of pancreatic cystadenoma or cystadenocarcinoma. METHODOLOGY: Retrospective analysis was made on the clinical data of 37 patients with pancreatic cystadenoma and 48 patients with cystadenocarcinoma from 1998 to 2005. RESULTS: Carcinoembryonic antigen (CEA), and CA19-9 of the cyst fluid and serum combined with EUS-guided fine needle aspiration biopsy was made. Examination of serum CEA, and CA19-9 resulted in 21.0+/-18.0, 2.7+/-1.7 U/L and 18.7+/-17.5, 269.0+/-182.0 U/L for cystadenoma and cystadenocarcinoma respectively (P<0.05). The sensitivity of cyst fluid combined with biopsy was higher than that of a single marker. However, the sensitivity and specificity of tumor markers of cystic fluid were much higher than that of the serum (P<0.05). CONCLUSIONS: EUS-guided fine needle aspiration biopsy combined with examination of cyst fluid level of CEA and CA19-9 will be a credible means for early diagnosis of pancreatic cystadenoma and cystadenocarcinoma.
