Tips for Better EGFR Mutation Testing

Molecular testing of genomic alterations in the EGFR gene is critical to personalized treatment decisions for patients with advanced non-small cell lung cancer (NSCLC). However, the testing landscape is complex. Some mutations confer sensitivity, and others confer resistance to anti-EGFR targeted therapies.

Extracting Formalin-fixed, paraffin-embedded (FFPE) nucleic acids for NGS

Answering frequently asked questions (FAQs)

Posted by Yves Konigshofer on Mar 14, 2017 11:20:00 AM

In the course of patient care, formalin-fixation and paraffin-embedding (FFPE) of biopsy tissue samples are routinely performed, where these samples can be analyzed by histology and archived to link the sample with clinical long-term follow-up. With the development of advanced NGS-based oncology gene panels, it is becoming increasingly important to consider pre-analytic variables when extracting nucleic acids from FFPE-treated samples. This post covers frequently asked questions (FAQs) around the extraction of nucleic acids from FFPE samples for downstream NGS analysis.

Video: What are the sources of variability in FFPE material?

Interview with Dr. Greg Tsongalis, Professor of Pathology, Dartmouth-Hitchcock Medical Center

Posted by Dale Yuzuki on Oct 27, 2015 11:16:00 AM

In this video interview Dr. Greg Tsongalis addresses sources of pre-analytic variability when processing formalin-fixed, paraffin-embedded (FFPE) samples in a pathology laboratory setting. By 'pre-analytic', he refers to the kinds of kits used for DNA extraction, and other factors that may have a significant impact on the quality of the results. He also discusses his work on clinical assay development for somatic mutation detection using NGS technology.
