Background: Testing for carcino-embryonic antigen (CEA) in the blood is a recommended part of follow-up to detect recurrence of colorectal cancer following primary curative treatment. There is substantial clinical variation in the cut-off level applied to trigger further investigation. Objectives: ...
it is expected to fall to normal following successful surgery to remove all of the cancer. A rising CEA level indicates progression or recurrence of the cancer. This must be confirmed , as the CEA test by itself

TheCA-125 blood testis used to detect the level of the protein, CA-125, which is referred to as a “tumor marker.” This test can sometimes be helpful in identifying ovarian cancer because cancer cells in the ovary release this protein into the body. However, there are other conditions not...
To demonstrate the clinical feasibility of our CRC early detection method, we assessed plasma CEA levels in the validation cohort and compared the performance of these assays to our integrated model. The sensitivity and specificity of CEA levels were 53.9% and 82.4%, respectively, and the ...
The conventional approach of generating clinical opinions from general blood test (GBT) results uses the deep neural network (DNN) comprised of fully-connected layers. The large number of input neurons and output neurons result in the complex DNN structure, which causes overfitting problem. However,...
Tracked over time, the level of CEA in the blood may help your doctor understand your treatment outlook and whether the cancer is responding to the treatment protocol. However, this test is not specific to colon cancer and may also be negative in other types of colon cancers. It should be...
They measured the levels of IDH1, CA125, Cyfra21-1, and CEA in blood samples from 1,422 participants, including 943 NSCLC patients and 479 healthy controls. The samples were randomly divided into a training set and a test set. The researchers used receiver operating characteristic (ROC) ...
