				        	Objective To study the role of preoperative CA19-9 level in predicting resectability of pancreatic cancer.Methods Preoperative CA19-9 levels were determined by radioimmunoassay.The receiver operating characteristic curve was used to determine the cut-off point.The clinical value of the level of CA19-9 as a predictive marker of resectability was evaluated by the area under curve.Results The preoperative CA19-9 levels in the resectahle group was (313.6±515.5) kU/L,which was significantly lower than (852.1± 865.1)kU/L in the unresectable group (P<0.001).The cut-off point of CA19-9 for predicting pancreatic cancer resectability was 312.1 kU/L,which had a sensitivity of 56.6% and a specificity of 73.3%.The area under curve was 0.67.Conclusions The preoperative CA19-9 level may be used to predict resectability of pancreatic cancer.
