Detailed Description

To assess the quantitative real time PCR results of oligonucleotide probes for a number of gene transcription products that may be useful as predictors or indicators of response to celecoxib, the feasibility of performing six different molecular assays by qRTPCR on formalin fixed paraffin embedded tissue obtained from breast cancer core biopsies and breast cancer reexcision patients, to assess change in Ki-67, PCNA, and several other markers by qRTPCR, correlate change in expression of Ki-67, PCNA, CAX-2, and bcl-2, measured by immunohistochemistry to change measured by qRTPCR, and to determine the reliability of the qRTPCR and immunohistochemical assays by performed selected assays on the same tissue in two different institutions
