Clinical Breast Care Project • Collaboration between WRI and WRAMC • 10,000 breast disease patients/year • Ethnic diversity; “transient • Equal access to health care for breast disease • All acquired under SINGLE PROTOCOL • All reviewed by a SINGLE PATHOLOGIST • 2 military, 1 non-military site added 2003 • 6 military sites to be added 2006 • Breast cancer vaccine program (her2/neu)
CBCP Repository • Tissue, serum, lymph nodes (>15,000 samples) • Patient annotation (500+data fields) • Patient Diagnosis = {130 sub-diagnoses} • Mammograms, 4d-ultrasound, PET/CT, 3T MRI • Complementary genomics and proteomics, IHC
Defining a Patient • A 48 year old woman, married, 2 children (ages 18, 24), presents with an abnormal mammogram, biopsy shows presence of cancer which, upon extraction, is diagnosed as invasive ductal carcinoma (T3,M1,N1). Her2/neu testing is +2

Conclusions • Personalized Disease will improve Patient Care, Today; Personalized Medicine, Tomorrow • Disease is a Process, not a State • Translational Medicine must be both: • Bedside-to-bench, and • Bench-to-bedside • The processes of aging are critical: • For accurate diagnosis of the patient • For improving treatment of chronic disease
