Background/aim: There are two strategies for the interpretation of tumor markers (TM) in fluid effusions: i) high cut-off and ii) fluid/serum ratio (F/S) and low cut-off. The objective of this study is to compare these two strategies and to determine whether diagnostic accuracy improves by the identification of possible false positives using Adenosine deaminase (ADA), C reactive protein (CRP) and % of polymorphonuclear cells (%PN).
Patients And Methods: We studied 157 ascitic fluids, 74 of which were malignant.
Background & Aims: T1 colorectal polyps with at least 1 risk factor for metastasis to lymph node should be treated surgically and are considered endoscopically unresectable. Optical analysis, based on the Narrow-Band Imaging International Colorectal Endoscopic (NICE) classification system, is used to identify neoplasias with invasion of the submucosa that require endoscopic treatment. We assessed the accuracy of the NICE classification, along with other morphologic characteristics, in identifying invasive polyps that are endoscopically unresectable (have at least 1 risk factor for metastasis to lymph node).

- Researchers studied the usefulness of two tumor markers, CA125 and CYFRA21-1, to help diagnose cancer in patients who had a buildup of fluid in their abdomen (ascites).
- They tested these markers in 143 patients and found that using both together improved the chances of correctly identifying cancer.
- The study suggests that checking these tumor markers could be helpful for doctors when figuring out if someone with ascites has cancer.
