Elevated CA 15.3 in Newly Diagnosed Breast Cancer
"This retrospective study evaluating the association of baseline cancer antigen (CA) 15.3 with primary or secondary metastatic disease in breast cancer showed that, in patients with newly diagnosed breast cancer, baseline CA 15.3 levels of more than 30 kU/L corresponded with a higher risk of both primary and secondary metastatic disease." (bolding and underlining added)
"Current guidelines do not recommend testing for CA 15.3 in a non-metastatic setting. This first-of-its-kind study suggests that the tumor subtype and baseline CA 15.3 levels may help identify patients with newly diagnosed breast cancer at risk for primary or secondary metastatic disease."
