Negative Serum Carcinoembryonic Antigen has Insufficient Accuracy for Excluding Recurrence from Patients with Dukes C Colorectal Cancer: Analysis with Likelihood Ratio and Posttest Probability in a Follow-Up Study

“…To date, many reports have focused on the most appropriate methods to choose and when they should be applied, so that cancer recurrence can be detected more effectively. 1,2 Carcinoembryonic antigen (CEA) is a cell surface glycoprotein that is produced by 90 percent of colorectal cancer 3,4 and that contributes to the malignant characteristics of the tumor. Quantitative measurements of serum CEA can be performed easily, and CEA is commonly used as a marker of colorectal cancer recurrence.…”

A prospective study comparing multi-gene biomarker chip and serum carcinoembryonic antigen in the postoperative surveillance for patients with stage I–III colorectal cancer

“…Of the numerous reported follow-up strategies, serial CEA monitoring is the most sensitive for detecting recurrence compared with historytaking, physical examination, liver function tests, abdominal sonography, chest radiography, and colonofiberoscopy; it remains one of the most crucial postoperative work-ups [23][24][25].…”

Duplexsonographie der Lebergefäße - eine Übersicht

“…Ergebnisse duplexsonographischer Messungen der Leberarterien wurden bei Hepatitis [26,27], Leberzirrhose [17,22,28] und bei malignen Tumoren der Leber [11,13,29,30] publiziert. Andere Parameter wie der Resistance Index oder die Querschnittsfläche zeigen keine bedeutenden geschlechtsspezifischen Unterschiede [32].…”
