To determine the sensitivity and specificity of the tumor marker Ca 19.9 in subjects with suspected pancreatic cancer.
Levels of Ca 19.9 antigen were measured by enzymeimmunoassay during a 3 year period to 72 patients investigated for suspected pancreatic cancer.
A threshold of 100 U/ml resulted in sensitivity of 94.7%, specificity of 39.6%, positive predictive value of 36% and negative predictive value of 95.4%.
Levels of Ca 19.9 antigen > 100 U/ml are suggestive of malignancy in patients investigated for suspected pancreatic cancer.
确定肿瘤标志物Ca 19.9在疑似胰腺癌患者中的敏感性和特异性。
在3年期间，采用酶免疫分析法对72例疑似胰腺癌患者检测Ca 19.9抗原水平。
阈值为100 U/ml时，敏感性为94.7%，特异性为39.6%，阳性预测值为36%，阴性预测值为95.4%。
疑似胰腺癌患者中，Ca 19.9抗原水平>100 U/ml提示恶性肿瘤。
