癌抗原CA19-9 CA19-9 Cancer Antigen 货号：P291-4 

CA19-9 is elevated in blood, primarily in patients with carcinoma of the gastro-intestinal tract. Higher levels are more likely to be due to malignancy than lower levels, however very high levels are occasionally seen in patients with benign conditions such as cirrhosis. CA19-9 is not sufficiently specific for use as a screening test, its greatest usefulness is with pancreatic cancer compared with pancreatitis. The specificity for pancreatic cancer increases with increasing levels, high levels showing a specificity of >97%.

CEA Antigen (recombinant) 癌胚抗原  货号：P824-3

CEA was first identified in human colon carcinoma tissue extracts and is known to play a critical role as a ligand in cancer dissemination. Elevated serum CEA is found in 17∼47% of colorectal cancer patients. CEA was originally thought to be a specific marker for colon cancer but levels may also be raised in gastric, pancreatic, lung, breast and medullary thyroid carcinomas, as well as some non-neoplastic conditions such as inflammation, pancreatitis, ulcerative colitis, cirrhosis, COPD, Crohn's disease, hypothyroidism and in smokers. For this reason, it is not useful as a general cancer screening tool, but can be useful in evaluating the response to cancer treatment, to monitor metastasis of colorectal cancer to the liver and to indicate recurrence. Elevated CEA levels should return to normal after successful surgical removal of the tumour and can be used in follow up, especially of colorectal cancers. CEA elevation is known to be affected by multiple factors and it varies inversely with tumor grade; well-differentiated tumours secrete more CEA.

CA15-3 Cancer Antigen 癌抗原CA15-3 货号：P301-4

CA15-3 is a normal product of breast cells, however in cancer it is frequently over-expressed. The CA15-3 marker is most widely used for monitoring the response to therapy of breast cancer patients. It is elevated in up to 70% of patients with metastatic disease, however, as it is only elevated in 3% of those with localised cancer there is no role for screening with this marker.
