Princess Alexandra Hospitals NHS Trust Breast Family History Clinic Background Overview of cancer genetics Referral Risk assessment The Family History appointment The Genetics appointment Risk-Reducing surgery Drawing a pedigree Examples and group work!!!

Background 1 in 9 women get breast cancer (Chalmers et al 2003) 5% BRCA 1/2 TP53 (Grande et al 2002) Familial Breast Cancer - 20% (Agnantis 2003) The general population is becoming increasingly aware of and concerned with their family history and it’s impact on their health. Women frequently over-estimate their risk (Martin % Degner 2006)

Primary Care – Population Risk Written information –Breast Awareness –NICE Guidelines –Pedigree Contact Details
11
Risk Assessment “Risk assessment is the first step in the process of providing information and support to patients and their families”(Silvell et al 2009)
12
NICE GUIDELINES All relatives on same side of family First Degree (FDR) – parent, full sibling, child Second Degree(SDR) – aunt/uncle, niece/nephew, half-sibling, grandparent/child Third Degree – great grandparent/child, great aunt/uncle, cousin
13
NICE GUIDELINES- Secondary 1 FDR Breast Cancer (BC) <40 2 FDR/SDR BC(at least one must be a FDR) 3 or more FDR/SDR BC 1 Male FDR BC 1 FDR bilateral BC 1 FDR/SDR Ovarian Cancer & 1 FDR/SDR BC (one must be a FDR) Any less than this and the patient falls into the Primary care Group
14
NICE GUIDELINES - Tertiary Breast Cancer 2 FDR/SDR* BC < 50 3 FDR/SDR* BC < 60 4 or more FDR/SDR* BC *one must be FDR
15
NICE GUIDELINES - Tertiary Ovarian Cancer 1 OC + 1 FDR BCor SDR BC <50or 1 OCor 2 FDR/SDR BC <60
16
NICE GUIDELINES - Tertiary Bilateral Breast Cancer 1 FDR BBC <50 1 FDR/SDR BBC + FDR/SDR BC <60
17
NICE GUIDELINES - Tertiary Male Breast Cancer 1 Male BC + 1 FDR/SDR BC <50or 2 FDR/SDR BC <60
18
Unusual Cancers Bilateral Breast Cancer Male Breast Cancer Ovarian Cancer Sarcoma <45 Glioma or childhood adrenal cortical carcinoma Complicated patterns of multiple cancers at young age
19
The Family History Appointment Secondary Care - moderate Risk Seen annually between ages 40-50 –Mammogram –Clinical Examination –Review
20
The Family History Appointment Tertiary Care - high risk Referral to Genetics Counsellor Seen annually aged 30-50 Then every 18 months –Mammogram if over 40 –MRI as indicated –Clinical Examination –Review
21
MRI Surveillance Subject to availability Annually to patients with a 10 year risk of –8% if aged 30-40 –20% if aged 40-49 BRCA1/BRCA2/TP53 carriers/at high risk of carrying
22
Risk-Reducing Surgery Bilateral Mastectomy reduces breast cancer risk by approx 90% (Hartmann et al 1999) Bilateral Salpingo-oopherectomy reduces ovarian cancer risk by approx 80% (Finch et al 2006) reduces breast cancer risk by approx 57% in BRCA 1 and 46% in BRCA 2 mutation carriers (Eisen et al 2005)
23
Drawing a Pedigree Taking a history –Ashkenazi Jewish Ancestry –Three generations –All cancer primaries –Age at diagnosis –Date of birth –Age at death –Any other serious illnesses/operations –? Bilateral –Male relatives –Unaffected relatives –Environmental exposure
