Study Start Date: January 2003
Estimated Study Completion Date: December 2005
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

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • women with a recent diagnosis of T1 or T2 noninvasive breast cancer by large core needle or excisional biopsy
  • confirmation that tissue was processed in methods acceptable to protocol and sufficient tissue remains post diagnostic analyses to perform research assessments
  • reexcision planned within 10 days to 6 weeks from study start

Exclusion Criteria:

  • no hormone replacement therapy within 90 days prior to biopsy
  • no history of asthma, allergy ASA, NSAIDS, celecoxib of other COX-2 inhibitors for a chronic non-oncological condition with the excision of low dose ASA (160 mg daily) during 4 weeks prior to biopsy and for the duration of the study
  • no celecoxib or rofecoxib use within one month of biopsy
  • no history of gastrointestinal ulcer or ulcerative colitis requiring treatment
  • no current anticoagulants
  • no neoadjuvant antihormone or chemotherapy as treatment following biopsy prior to study entry or concurrently with participation on study
  • no aromatase inhibitor in the six months prior to participation
  • no concomitant lithium
  • no known significant bleeding disorder
