LP15461-4   Cancer Ag 15-3
Cancer antigen 15-3 (CA 15-3) is a mucin molecule and blood tumor marker used to gauge the response to treatment of invasive breast cancer. CA 15-3 is encoded by the MUC1 gene and is a transmembrane glycoprotein. CA 15-3 may contribute to the growth of breast tumors by preventing tumor cell cytolysis by cytotoxic T-cells or lymphokine-activated cells. It may also block the proliferation of T-cells by causing apoptosis. In addition, CA 15-3 has been found to be expressed over the entire cell in malignant breast tissue while normal breast tissue expresses CA 15-3 only on the apical side of the glanudular epithelial cells. The presence of CA 15-3 is not unique to patients with breast cancer, but can also be found in patients with lung, colorectal, ovarian, and pancreatic cancers. Patients with primary tumors tend to have lower levels of CA 15-3, though the average concentration and percentage of patients goes up as the tumor stage or size of the tumor increases. While only a small number of recurrences of local or regional tumors result in an increased CA 15-3 level, over 70% of patients with remote metastasis have much higher CA 15-3 levels.

LP7037-7   Asp
In LOINC, the System "Asp" represents the fluid withdrawn during an aspiration procedure from an abnormal collection of fluid, such as from an abscess or cyst. "Asp" should not be used to represent named body fluids, such as synovial fluid or peritoneal fluid, because those fluids are not inherently pathologic and also, they have their own named Systems in LOINC.
