Genomic Assays in the “Real” Oncology World — Part 1: Genomic Assays and Colorectal Cancer — Featuring a roundtable discussion with Drs Emmanuel S Antonarakis, Johanna Bendell, Ian E Krop and Andrew McKenzie.
- Multiplex Genomic Assays and Their Role in Therapeutic Decision-Making
- Case: A man in his mid-80s with metastatic castration-resistant prostate cancer (mCRPC) whose disease progressed through multiple therapies is found to have CD274 (PD-L1) amplification, microsatellite instability (MSI)-high status and mutations in ATM and EGFR
- Effect of CD274 amplification on response to immune checkpoint inhibitors; activity of PARP inhibitors in patients with ATM mutations
- Advantages and limitations of multiplex genomic testing
- Role of serial testing to identify variations in genomic mutations or aberrations over time; potential benefit of liquid next-generation sequencing (NGS) panels
- Use of multiplex genomic assays by community oncologists and implications for clinical practice
- Optimal timing of genetic testing for patients diagnosed with metastatic disease
- Presentation (Dr McKenzie): Overview of multiplex genomic assay methodology
- Rationale for the use of serial testing and liquid assays to identify variations in genomic mutations or aberrations over time
- Differentiating between germline and somatic mutations in cancer tissue
- Perspective on the use of tissue versus liquid biopsy for genetic testing
- Sensitivity of liquid biopsies in detecting tumor mutations
- Available data exploring the impact of NGS use on patient outcomes
- Selection of a multiplex genomic assay for detecting genetic alterations
- Implications of multiplex genomic assay results for therapeutic decision-making
- Comprehensive Genetic Profiling and Precision Medicine for Metastatic Colorectal Cancer (mCRC)
- Specific biomarkers and genetic alterations routinely evaluated in clinical practice
- Effects of up-front multiplex genomic assay testing on outcomes for patients with mCRC
- Response to immune checkpoint inhibitors in patients with MSI-high mCRC (1:09:3s
- Presentation (Dr Bendell): Biomarker assessment in mCRC; role of multiplex testing
- Actionable genetic alterations in mCRC; detection of BRAF and HER2 mutations and implications for practice
- Rationale and indications for the assessment of MSI and DNA mismatch repair (MMR) status; emerging role of tumor mutational burden
- Role of liquid versus tumor biopsies for detecting genetic alterations
- MSI/MMR and tumor mutational burden as predictors of benefit from immune checkpoint inhibitors
- Emerging role for the assessment of neoantigen load
- Case (Dr Bendell): A man in his mid-50s with mCRC, Lynch syndrome and MSI-high status achieves a partial response to pembrolizumab as second-line therapy
- Case (Dr Bendell): A woman in her early 60s with microsatellite stable mCRC and a BRAF V600E mutation receives the combination of cetuximab, encorafenib and binimetinib after disease progression on FOLFOXIRI/bevacizumab
- Case (Dr Bendell): A man in his early 40s with HER2-positive mCRC receives trastuzumab and pertuzumab on a clinical trial after disease progression on FOLFIRI/bevacizumab and attains a partial response
- Novel HER2-targeted therapies under evaluation for patients with mCRC and HER2 alterations
- Analysis of the gut microbiome and strategies to enhance the immune response to cancer
