Australian Ovarian Cancer Study AOCS summary Highlights of publications to date Genome Wide Association Study for progression free survival Ovarian Cancer Association Consortium
1,859 case women with ovarian, fallopian tube and primary peritoneal cancer recruited through treatment centres & cancer registries across Australia (1,097 frozen tissues), plus ascites at relapse 1,066 control women recruited, selected at random from Commonwealth electoral roll Lifestyle and Diet questionnaire Lifestyle and Diet questionnaire Blood sample Frozen tumour specimen Frozen tumour specimen Treatment and clinical details Treatment and clinical details Patient recruitment Control recruitment Epidemiology Core Brisbane Biospecimen Core Melbourne Clinical Follow-up Core Sydney www.aocstudy.org 2002 - 2006 PI: David Bowtell
AOCS: Clinical Follow-up Clinical follow-up at 6 month intervals (GCP guidelines) Date of relapse assigned according to GCIG criteria (CA125) Serum CA125 level Surgery Relapse PFS PI: Anna deFazio Jillian Hung

AOCS: an international resource 79 approved national and international projects 88 publications on ovarian cancer 2007 2008 2009 2010 2011 2012
14.1% frequency (95% CI: 11.9-16.3%) of pathogenic mutations; increases to 16.6% (95% CI: 13.9-19.3%) in serous tumours 44% (62/141) of the mutation carriers did not report a strong family history of breast and/or ovarian cancer The overall frequency (14.1%) is high enough to suggest that genetic testing should be offered to all women Can we show that mutation status also has an important prognostic and clinical role to play in ovarian cancer management …? 2012 PATHOGENESIS

Genome Wide Association Study (GWAS) of progression free survival following treatment of ovarian cancer with carboplatin and paclitaxel Georgia Chenevix-Trench Queensland Institute of Medical Research
Hypothesis That Single Nucleotide Polymorphisms (SNPs) in chemoresponse mediators are associated with progression- free survival in women receiving paclitaxel and carboplatin for advanced ovarian cancer Primary: that chemoresponse SNPs are associated with ovarian cancer progression in women receiving > 4 cycles of paclitaxel (175 or 135 mg/m 2 ) and carboplatin (AUC 5 or 6) Secondary analysis; also includes cases with > 4 cycles of unknown doses (Carboplatin IV AUC ? + Paclitaxel IV ? mg/m 2 ) Tertiary analysis: all invasive cases regardless of chemotherapy - to determine if particular genotypes are related to PFS or OS, independent of treatment
Secondary analysisTertiary analysis SNPHR95%CIPHR95%CIP PFS rs78740432.47[1.72,3.53]7.96x10 -7 1.48[1.14,1.91]3.35x10 -3 rs727006532.57[1.72,3.84]4.14x10 -6 1.38[1.05,1.83]2.23x10 -2 Association of two genotyped SNPs in TTC39B with PFS r 2 = 0.896
TTC39B rs7874043 with PFS for individual studies in Stages 1 and 2 combined Primary Secondary Tertiary
TTC39B and high density lipoprotein-cholesterol TTC39B (c9orf52) encodes tetratricopeptide repeat domain 39B, a potential transmembrane protein two GWAS for lipid levels have identified common SNPs in this locus associated with HDL-C levels (Teslovitch et al., 2010) knockdown of TTC39B in a mouse model results in elevated levels of HDL-C genetic variant in TTC39B may affect response to statins
Collaborative Oncological Gene-Environment Study Breast Cancer Association Consortium - BCAC Ovarian Cancer Association Consortium - OCAC Consortium of Investigators of Modifiers of BRCA1/2 - CIMBA Genotyped in 103,991 breast cancer cases and controls 39,774 ovarian cancer cases and controls (including AOCS) 11,705 BRCA1 and BRCA2 carriers Telomere length was measured in 15,567 control subjects of two BCAC studies
