14. What is a driver mutation?
Biological definition: a mutation that directly or indirectly confers a selective growth
advantage to the cell in which it occurs
Clinical definition: a mutation that has significant diagnostic, prognostic, or therapeutic
implications in subsets of cancer patients and for specific therapies

19. NGS: Various Approaches
• Whole Genome Sequencing (WGS)
– Determines the complete DNA sequence of an organism's
genome at a single time
• Whole Exome Sequencing (WES)
– Selectively sequences only the coding areas of the genome
• Comprehensive Genomic Profiling
– Massively parallel sequencing of the entire coding region in a
defined subset of genes of interest and detects all four
classes of alterations
• Targeted Sequencing (Hot spot)
– Sequences only the hot spots of a subset of genes of
interest

24. Why FoundationONEHemeTM Test was
Developed
• Detects all clinically relevant classes of genomic alterations in
hematologic and soft tissue tumors
• DNAseq of the entire coding region of 405 genes and select intronic
regions in 31 genes known to be clinically & biologically relevant in
cancer
• RNAseq of 265 genes recurrently rearranged in cancer
• Validated high accuracy achieved by high, uniform coverage: at
median exon depth of 250x, >99.5% of exons covered >100X
• Requires only small amounts of fresh (peripheral blood/bone marrow
aspirate) or FFPE clinical specimens (≥50ng of DNA, lesional tissue >20%
of nucleated elements)
• Customized computational biology algorithms validated for high
accuracy in clinical samples with high stromal contamination

34. Complexity of Cancer Genome
• Cancer evolves & adapts (in a Darwinian fashion) to both host
defenses and to therapy - driven by clonal heterogeneity
• Clonal evolution contributes to resistance to therapy; treatment
may hasten the evolutionary process
• Functionality: Lineage specificity of genomic abn: BRAF V600E 
no response to vemurafenib in colorectal cancer; HER2
amplification  no benefit to trastuzumab in endometrial cancer
• Different areas of the genome may have different rates of
mutation acquistion and indeed the order
Hyman et al, NEJM 2015

35. Concluding thoughts
• Hybrid-capture NGS technology is enabling us
to deliver evidence-based precision cancer
medicine
• In the near future, comprehensive genomic
profiling will incorporate predictive
biomarkers for immunotherapy enabling even
greater clinical application
