Introduction to Genomic Profiling in Modern Oncology
What is Genomic Profiling?
Genomic profiling is the comprehensive analysis of tumor DNA or RNA to identify genetic alterations such as mutations, insertions, deletions, copy number changes, and gene fusions. This laboratory method can also include analysis of non-tissue samples like blood, pleural effusion, and ascites. It provides detailed insights into the molecular characteristics of a patient's cancer.
The Role in Personalized Cancer Treatment
By revealing tumor-specific genomic information, genomic profiling enables clinicians to tailor treatment strategies for individual patients. This approach helps identify actionable alterations that guide the choice of targeted therapies and immunotherapies. It also informs clinical trial eligibility, thereby broadening treatment options and improving patient outcomes.
Technological Advancements in Genomic Profiling
Next-generation sequencing (NGS) technologies have revolutionized genomic profiling by allowing the simultaneous analysis of hundreds of cancer-related genes with high sensitivity and accuracy. RNA-based assays complement DNA analysis by detecting gene fusions and alternative splicing variants that are critical in certain cancers. Innovations such as liquid biopsy using circulating tumor DNA facilitate non-invasive profiling, making genomic testing more accessible and effective in clinical settings.
Comprehensive Genomic Profiling: The Foundation of Precision Oncology
What is comprehensive genomic profiling (CGP) and how is it conducted?
Comprehensive genomic profiling (CGP) is a cutting-edge diagnostic tool that uses next-generation sequencing (NGS) technologies to analyze hundreds of genes linked to cancer. It detects a wide range of genetic alterations including single nucleotide variations (SNVs), insertions and deletions (indels), copy number alterations (CNAs), and gene fusions. CGP evaluates both tumor DNA and RNA sequencing to provide a detailed genetic blueprint of the tumor.
Next-generation sequencing technologies in CGP
NGS is the backbone of CGP, allowing for high-throughput, simultaneous sequencing of numerous cancer-related genes. This technology enhances sensitivity and accuracy, ensuring that even low-frequency mutations and complex structural variations are identified. Panels used in CGP can include hundreds of genes, such as the 435-gene CANCERPLEX assay, ensuring a comprehensive analysis.
Types of genomic alterations detected
CGP identifies various genomic alterations critical for targeted therapies. These include:
- Single nucleotide variations (SNVs): Small changes in individual DNA bases.
- Insertions and deletions (indels): Additions or losses of small DNA segments.
- Copy number alterations (CNAs): Gains or losses in sections of chromosomes.
- Gene fusions: Abnormal joining of two genes, often detected through RNA-based assays for gene fusion detection.
Additionally, CGP measures biomarkers like tumor mutational burden (TMB) and microsatellite instability (MSI) which guide immunotherapy decisions.
Use of tumor tissue and liquid biopsies in profiling
While tumor tissue biopsies remain the primary source for genomic profiling, liquid biopsies with circulating tumor DNA (ctDNA) assays from blood samples are increasingly utilized. Liquid biopsies offer a non-invasive alternative when tissue is scarce or inaccessible.
