Study of Calgranulin A/B Levels in Patients With Newly Diagnosed Stage I,II,III Breast Cancer
RATIONALE: Measuring levels of calgranulin A and calgranulin B in the blood of patients with breast cancer in the laboratory may help doctors identify and learn more about biomarkers related to breast cancer.
PURPOSE: This laboratory study is measuring calgranulin A and calgranulin B levels in the blood of patients with newly diagnosed stage I, stage II, or stage III breast cancer.

|Study Design:||Observational Model: Case-Only
Time Perspective: Cross-Sectional
|Official Title:||A Pilot Trial to Correlate Serum Levels of Calgranulin A and B With Estrogen Receptor Status Among Patients With Breast Cancer|
- Correlation between circulating levels of calgranulin A and calgranulin B and the presence of estrogen receptor negative breast cancer [ Time Frame: upon diagnosis ]
Biospecimen Retention: Samples With DNA
|Study Start Date:||January 2005|
|Study Completion Date:||December 2006|
|Primary Completion Date:||April 2006 (Final data collection date for primary outcome measure)|
Other: immunoenzyme technique
- Determine circulating levels of calgranulin A and calgranulin B in patients with estrogen receptor negative or estrogen receptor positive, newly diagnosed, primary stage I-III adenocarcinoma of the breast.
OUTLINE: This is a pilot study.
Patients undergo a blood draw following diagnosis of breast cancer to assess levels of circulating tumor markers, calgranulin A and calgranulin B. Serum samples are evaluated by enzyme-linked immunosorbent assay for tumor marker expression.
PROJECTED ACCRUAL: A total of 60 patients will be accrued for this study.
