Whole Genome Analyses of a Well-Differentiated Liposarcoma Reveals Novel SYT1 and DDR2 Rearrangements
2014
PLoS ONE
Liposarcoma is the most common soft tissue sarcoma, but little is known about the genomic basis of this disease. Given the low cell content of this tumor type, we utilized flow cytometry to isolate the diploid normal and aneuploid tumor populations from a well-differentiated liposarcoma prior to array comparative genomic hybridization and whole genome sequencing. This work revealed massive highly focal amplifications throughout the aneuploid tumor genome including MDM2, a gene that has

... y been found to be amplified in well-differentiated liposarcoma. Structural analysis revealed massive rearrangement of chromosome 12 and 11 gene fusions, some of which may be part of double minute chromosomes commonly present in well-differentiated liposarcoma. We identified a hotspot of genomic instability localized to a region of chromosome 12 that includes a highly conserved, putative L1 retrotransposon element, LOC100507498 which resides within a gene cluster (NAV3, SYT1, PAWR) where 6 of the 11 fusion events occurred. Interestingly, a potential gene fusion was also identified in amplified DDR2, which is a potential therapeutic target of kinase inhibitors such as dastinib, that are not routinely used in the treatment of patients with liposarcoma. Furthermore, 7 somatic, damaging single nucleotide variants have also been identified, including D125N in the PTPRQ protein. In conclusion, this work is the first to report the entire genome of a well-differentiated liposarcoma with novel chromosomal rearrangements associated with amplification of therapeutically targetable genes such as MDM2 and DDR2.

Clinical Implementation of Integrated Genomic Profiling in Patients with Advanced Cancers
2016
Scientific Reports
DNA focused panel sequencing has been rapidly adopted to assess therapeutic targets in advanced/ refractory cancer. Integrated Genomic Profiling (IGP) utilising DNA/RNA with tumour/normal comparisons in a Clinical Laboratory Improvement Amendments (CLIA) compliant setting enables a single assay to provide: therapeutic target prioritisation, novel target discovery/application and comprehensive germline assessment. A prospective study in 35 advanced/refractory cancer patients was conducted using

... LIA-compliant IGP. Feasibility was assessed by estimating time to results (TTR), prioritising/assigning putative therapeutic targets, assessing drug access, ascertaining germline alterations, and assessing patient preferences/perspectives on data use/reporting. Therapeutic targets were identified using biointelligence/pathway analyses and interpreted by a Genomic Tumour Board. Seventy-five percent of cases harboured 1-3 therapeutically targetable mutations/case (median 79 mutations of potential functional significance/case). Median time to CLIA-validated results was 116 days with CLIA-validation of targets achieved in 21/22 patients. IGP directed treatment was instituted in 13 patients utilising on/off label FDA approved drugs (n = 9), clinical trials (n = 3) and single patient IND (n = 1). Preliminary clinical efficacy was noted in five patients (two partial response, three stable disease). Although barriers to broader application exist, including the need for wider availability of therapies, IGP in a CLIA-framework is feasible and valuable in selection/prioritisation of anti-cancer therapeutic targets.

Eighteen of 66 treated patients (27%) were found to have progression-free survival (PFS) ≥1.3 times longer on the molecular profiling directed approach compared to their most recent empiric therapy (PFS ratio), allowing for rejection of the null hypothesis of <15% having PFS ratio ≥1.3. In a similar effort focused on patients treated on Phase I trials, Tsimberidou and colleagues assessed microdissected paraffin embedded tissue for somatic hot-spot exonal mutations in 10 genes (PIK3CA, BRAF, NRAS, KRAS, EGFR, KIT, GNAQ, MET, TP53 and RET), IHC for PTEN and FISH for ALK translocations in 1,144 patients 7 . They found that 460 (40.2%) of these patients had at least one genomic aberration. Notably, a higher response rate (27% vs. 5%; P < 0.0001), time-to-treatment failure (median 5.2 vs. 2.2 months; P < 0.0001) and longer survival (median 13.4 vs. 9.0 months; P = 0.017) were observed in patients who had matched therapy compared to those patients who had empiric therapy. While the scope of molecular profiling performed in these studies was limited compared to current NGS enabled approaches, they provide a contextual platform upon which clinical efforts utilising NGS could be implemented. NGS based approaches assaying a panel of genes 4 or a panel of genes in conjunction with array comparative genomic hybridisation (aCGH) 8 , provided further impetus towards more ambitious, comprehensive genomic characterisation in the clinical setting. More recently, a retrospective study by Jones and colleagues comparing whole exome sequencing to NGS panel based approaches, highlighted the high false positive rate and absence of germline analysis associated with NGS panels as major limitations 9 . Several other recent studies have further demonstrated the necessity of including germline analysis when evaluating somatic mutations 10-13 . Exploratory evaluations of whole exome, genome and transcriptome sequencing have demonstrated the technical feasibility of the approach. However, these efforts were limited (Weiss and colleagues [n = 9] 3 and Roychowdhury and colleagues [n = 4] 5 ) and identified numerous barriers that should be evaluated in future studies. These barriers include the ability to execute the workflow consistently in a Clinical Laboratory Improvement Amendments (CLIA) 14 environment and challenges in acquisition of sufficient, high-quality, NGS suitable tissue from prospectively collected samples. Furthermore, ethical, legal, and social implications (ELSI) are significant as these encompass the communication of incidental (unsolicited) findings from germline analysis, data custody and data privacy in the event of death prior to result availability. In addition, the delivery of results to treating physicians in a timeframe that is compatible with the opportunity to treat patients experiencing clinical decline while awaiting results and access to genome analysis guided therapeutics through on/off-label use of drugs or clinical studies, present very real barriers to implementation of comprehensive NGS technologies in the clinic. In response to these observed challenges, a study was designed to evaluate the effectiveness of implementation of comprehensive NGS technologies in a clinical setting. The study objectives were threefold. First, the study sought to estimate the time to completion of integrated whole exome/long insert whole genome/transcriptome sequencing. Second, the objective was to estimate time to reporting of results of therapeutically relevant drug targets derived from integrated whole exome/long-insert whole genome/whole transcriptome sequencing along with CLIA validation. Finally, the study sought to determine mechanisms of drug access.

Targeted sequencing using a 47 gene multiple myeloma mutation panel (M3P) in -17p high risk disease
2014
British Journal of Haematology
We constructed a multiple myeloma (MM)-specific gene panel for targeted sequencing and investigated 72 untreated high-risk (del17p) MM patients. Mutations were identified in 78% of the patients. While the majority of studied genes were mutated at similar frequency to published literature, the prevalence of TP53 mutation was increased (28%) and no mutations were found in FAM46C. This study provides a comprehensive insight into the mutational landscape of del17p high-risk MM. Additionally, our
