  6. Methods: After IRB approval, we conducted a retrospective chart review of 392 patients with breast cancer who had regular monitoring of CA 27.29 levels following the diagnosis of breast cancer. A total of 2671 values of CA 27.29 were evaluated from our institution over the past 5 years (2003–2008).
