► Male; metastatic tumour; prior to treatment

► BRAF, CDKN2A and PTEN mutations previously confirmed by exon

Somatic Substitutions in COLO-829

► Subtraction process– High stringency calibrated tumour calls (germline + somatic)

– Subtract if evidence of variant in normal; & dbSNP

► 33,345 somatic substitutions (gain of an allele) in total

– 1 per 100 kb

– 32,325 single base

– 510 double base (adjacent)

► 96.6% specificity

– 454/470 novel somatic calls confirmed by new PCR-capillary sequencing

– 16 may be artefacts of either method

► 88% (98%) sensitivity

– 42/48 previous somatic variants called automatically

– (98%) or 47/48 automatic + manual (five seen only manually as the evidence

was below automatic threshold)

– 1/48 disputed call

Difficult Dx

Patients present with a suspicious/palpable mass

Less than 40% are cured

204,449 New cases annually; 124,860 deaths

Early Dx is Key

Five year survival is good if diagnosed early,

but most patients are diagnosed late stage

Summary of TP53 somatic substitutions (SNVs)

► 14/17 high grade serous samples have TP53 somatic substitution variants

(SNVs) – further analysis of remaining samples ongoing

► Review vs. COSMIC:

– All are in known TP53 hotspots

– All are novel observations in ovarian cancer

– Two seen previously in other cancers

► TP53 mutations reported in 97% of high grade pelvic serous carcinoma

samples in a recent study (Ahmed et al 2010)

Summary and Future Prospects

► A Genome-Wide Opportunity:

– Comprehensive variant catalogues

– >95% specificity and ~90% sensitivity of somatic substitutions

► System developments enable large-scale studies:

– Chemistry, software improvements (>99.9% raw data accuracy)

– HiSeq2000 platform (>300 Gb per run: two 30x genomes per instrument per

week)

► Implications for individual genome sequencing:

– Understanding disease mechanism, biomarker discovery

– Sequencing individual cancer genomes for personalised treatment
