Personalising cancer medicine
one genome at a time
6. The Human Genome Project
$3 billion and 15 years…for one genome

[the Human Genome Project] done as quickly as possible”
8. Moore’s law
Moore’s Law” -- Proposed by Gordon Moore, co-founder of Intel, this law accurately projected that the transistor count on a microchip
would nearly double every two years. By extension, performance of computing would also double ever two years at similar costs. Four
decades later, transistor count has grown by a factor 105 and silicon technology has seeped into every aspect of our lives.
“Metcalfe Law” -- Attributed to Robert Metcalfe, co-inventor of Ethernet and founder of 3Com, this law proposes that the value of a
telecommunications network is proportional to the square of the number of connected users of the system. While a slightly obtuse
definition, in essence it suggests that the value of a network increases exponentially as you add more people to it.

12. CRUK Stratified Medicine
• Currently around 60 clinical tests (10 with clinical
utility in drug testing) on 5-10,000 patients per year
• Potential: BrCA54000, PrCa36000, OvCa6000, PaCa7000
(UK cases per year)
• 100,000 cases but which tests and how?
• Stratified Medicine Project: Sample collection,
Sample Prep, Throughput, Analysis, Ethics
• >2500 patients, 815 sets of cancer gene test
results
• 95% of patients agree to take part
• Current Sanger sequencing will be supplanted
by Next-Generation Sequencing
21. Understanding tumour evolution
Case 1 BrCA: After paclitaxel treatment an increase in the levels of a PIK3CA mutation,
these mutations are known to be involved in paclitaxel resistance.
Case 2 BrCA ER+, Her2+: After tamoxifen + trastuzumab treatment an initial increase in
the levels of a MED1 mutation, this is an ER co-activator and these mutations are known
to be involved in tamoxifen resistance. After secondary therapy with lapatinib +
capecitabine a mutation in GAS6 was linked to activation of the AXL tyrosine-kinase
receptor which is known to be involved with lapatanib resistance.
Case 4 OvCA: After cisplatin treatment an increase in the levels of a RB1 mutation, which
was also seen in 95% of reads from the metastatic biopsy. RB1 loss is known to be
involved in chemotherapy resistance.
Case 6 NSCLC: After gefitinib treatment an EGFR mutation was detected with digital-PCR,
this mutation is known to inhibit binding of gefitinib to EGFR and is the main driver of
gefitinib resistance.
