End points of cancer registry • Incidence • Mortality • Temporal trends in incidence and mortality To allow for a rational planning of cancer control
Breast Cancer in the last decade • Increased Incidence: • lack of efficacy of primary prevention • Decreased mortality: • Efficacy of secondary prevention (screening) • More efficacious treatments • In the adjuvant setting • In the metastatic setting
Adjuvant Chemotherapy for Breast CancerBeyond anatomic staging: is it time to take the leap into molecular era?Working group
Breast Cancer Registry and Molecular Subtypes • Prevention • Treatment • Follow up
BRCA 1 & 2 location tumor BRCA 1 17q21 breast, ovary,prostate BRCA2 13q13 breast, male breast, colon pancreas
BRCA 1 & 2 Surveillance Healthy carriers • Breast • Breast self-exams • Clinical breast exams • Mammography • New technologies ..(MRI) • Ovary • Clinical examinations • Pelvic ultrasound • Transvaginal ...ultrasound • CA 125
BRCA 1 & 2 Prophylaxis Healthy carriers • Chemoprevention: • tamoxifen • droloxifen • raloxifen • AIs • Prophylactic mastectomy • Chemical castration • Prophylactic bilateral oophorectomy

How many breast cancers are HER2+ ? • 15-25% (Slamon DJ, Science 1987) • 10- 34% (Molecular Oncology of Breast Cancer, JS Ross&GN Hortobagyi,2005) • ~ 20 % (NCI; www.cancer.org 2005) • 14.5 % (Modena Cancer Center, 2005)
HER2+ and Age • Median age in trials 49 y • Median age (Omero project) 53 y • Median age (Modena Cancer Center) 56 y Median age of Breast Cancer patients in Modena Cancer Registry: 62.3 yrs

Annual risk of recurrence by ER Saphner T, et al. J Clin Oncol 14: 2738, 1996
Breast Cancer Registry and Molecular Subtypes • Molecular subtypes of breast cancer: - require different diagnostic procedures - may have different risk/benefit ratio for preventive interventions - respond differently to treatments - have different annual risk of relapse A population-based registry of the molecular subtypes of breast cancer would allow a more rational planning of resource allocation
