ABSTRACT:
A method of determining the proliferative status of a carcinoma is disclosed. One obtains a patient sample and then quantitatively analyzes the sample for NGAL gene expression product. The amount of NGAL expression product is compared with a standard curve to determine the S-phase value. The sample can be breast tissue or breast fluid aspirate. Alternatively, blood can by analyzed for this marker to diagnose metastasis.
