Roles for clinical labs • Address all phases of testing • Pre-analytical, analytical, post-analytical • Fulfill clinical needs (and wants) • Criteria • Provide quality for patient safety • Maintain regulatory compliance • Achieve fiscal goals
New roles for the pathologist • Assay selection and development • Clinical therapeutics consultation • Specimen acquisition and qualification • Assay quality control/quality assurance • Assay results interpretation • Regulatory and fiscal environment • Competitive environment
NGS strategies • Whole genome sequencing (WGS) • Somatic mutations in tumor • Germline mutations and polymorphisms • Whole exome sequencing (WXS) • Sequencing of targets for actionable alterations (ACGS) • Informatics support
NGS strategies for clinical labs • The driver: Clinical utilization of sequence data • The problem of reporting complex results in clinically understandable format • “Umbrella” trials of new targeted agents • Novel usage of existing agents to target pathways • Novel combinations of agents • Validated and actionable data
NGS beyond nucleotide substitutions • Small insertions and deletions (indels) • Copy number variations • Amplifications • Losses • Chromosomal re-arrangements • Methylation • Gene expression • Functional genomics
Evaluation of evidence • Levels • Green and Byar, 1984 • TMUGS, 1996 • Lassere et al., 2007 • NCCN Task Force, 2011 • Depth • Breadth
New roles for the pathologist • Assay selection and development • Clinical therapeutics consultation • Specimen acquisition and qualification • Assay quality control/quality assurance • Assay results interpretation • Regulatory and fiscal environment • Competitive environment
Clinical therapeutics consultation Drugs for a patient, or patients for drugs. Manuel Hidalgo, MD Clinical care or clinical trial
New roles for the pathologist • Assay selection and development • Clinical therapeutics consultation • Specimen acquisition and qualification • Assay quality control/quality assurance • Assay results interpretation • Regulatory and fiscal environment • Competitive environment
Quality of specimens • Labile analytes • mRNA • Proteins • Phosphoproteins • Smaller samples • Real-time non-destructive qualification (e.g. optical confluence tomography)
Quality of specimens • Fit-for-purpose selection of sources • Primary tumor • Metastatic tumor • Non-neoplastic control tissue for specific assays: peripheral blood leukocytes or tissue • Elapsed time between specimen and test • Potential effects of prior therapy • Circulating tumor cells
New roles for the pathologist Intratumoral heterogeneity
Tumor heterogeneity • Importance for analytes of interest: Comparison of primary CRC to metastasis and comparison among metastases • KRAS: Relatively concordant (90%) • NRAS: Highly discordant • Loss from primary • Acquisition in metastasis • Size of abnormal subpopulations
New roles for the pathologist • Assay selection and development • Clinical therapeutics consultation • Specimen acquisition and qualification • Assay quality control/quality assurance • Assay results interpretation • Regulatory and fiscal environment • Competitive environment
New roles for the pathologist • Assay selection and development • Clinical therapeutics consultation • Specimen acquisition and qualification • Assay quality control/quality assurance • Assay results interpretation • Regulatory and fiscal environment • Competitive environment
The regulatory environment • CLIA vs. FDA • Laboratory-developed tests (LDTs) • Complex assays • FDA • Companion diagnostics • NCI Cancer Diagnostics Program (CDP) • Professional organizations: ASCO, NCCN, CAP, ASCP, AMP, IOM, etc., etc. • Gene patents
The fiscal environment The $1,000 genome, the $100,000 analysis. Elaine Mardis, PhD Washington University, St. Louis
The fiscal environment • Who wants to pay? • Who pays? • Who gets to decide?
