Medical Crossfire®: How to Use Liquid Biopsies Throughout the Lung Cancer Treatment Continuum Online

Release Date: January 31, 2018
Expiration Date: January 31, 2019
Media: Internet - based

 

Activity Overview

Online Activity - Medical Crossfire®: How to Use Liquid Biopsies Throughout the Lung Cancer Treatment Continuum will update oncology healthcare professionals involved in the treatment of patients with lung cancer by providing expert guidance, interpretation, and opinions on the importance and impact of liquid biopsy testing through multiple lines of therapy. This activity features 4 modules, which will present multiple expert points-of-view on this rapidly evolving area of molecular testing. In Module 1, the role of tumor genotyping in treatment decision making will be discussed, as well as the strengths and weaknesses of conventional tissue-based testing. Module 2 will outline the scientific basis for liquid-based molecular testing, including current data on the levels of concordance between liquid- and tissue-based genotyping. Module 3 will incorporate case-based discussion on the real-world application of liquid biopsies, including issues regarding turnaround time, sensitivity, and specificity. Finally, Module 4 will address outstanding questions and potential future applications of liquid-based biopsies.

PER Pulse Recap™

PER Pulse Recap (1 of 3)

This first of 3 PER Pulse™ Recaps from this Medical Crossfire® focuses on the role of tissue-based testing and challenges faced with this approach.
  • In lung cancer, a tissue biopsy is the gold standard. This approach, however, does have potential drawbacks, including increased expenditures from adverse events or complications during biopsy. A retrospective analysis from a Medicare database of 8979 patients showed that a complication (eg, pneumothorax) could quadruple the cost of a biopsy from approximately $9,000 to approximately $38,000.
  • An additional challenge with tissue biopsies is the possibility of insufficient tissue obtained. A study of 102 patients at the University of Pennsylvania showed that tissue-based molecular testing was successful in only half of the patients, most often because of a lack of tissue.
  • Given that cell-free DNA can be detected in patients with cancer, this raises the possibility of a less invasive approach to analyze tumor DNA.

PER Pulse Recap (2 of 3)

This second of 3 PER Pulse™ Recaps from this Medical Crossfire® focuses on the sensitivity of plasma-based testing and clinical applications of plasma-based test results.
  • An examination of plasma-based testing carried out by Oxnard et al showed that plasma-based testing had a sensitivity of 82% to 86% of that of tissue-based testing for the sensitizing exon 19 or exon 21 mutation in the epidermal growth factor receptor (EGFR), and the sensitivity was 70% for the T790M resistance mutation.
  • Patients in this study who had progressed on a first-line EGFR inhibitor and who had a positive result, by plasma-based testing, for T790M had outcomes similar to those with a positive result from tissue-based testing. However, the outcome with a negative T790M result by plasma differed from the outcome in T790M-negative disease by tissue-based testing. Therefore, a true positive T790M result by plasma may be sufficient to recommend osimertinib; however, a negative result by plasma should be confirmed by tissue-based testing.

PER Pulse Recap (3 of 3)

This third of 3 PER Pulse™ Recaps from this Medical Crossfire® focuses on first-line epidermal growth factor receptor inhibition and the sensitivity of plasma-based testing in this setting.
  • The phase III FLAURA trial compared osimertinib to erlotinib or gefitinib as first-line therapy in patients with EGFR mutation–positive lung cancer and led to approval of osimertinib in this setting based on superior progression-free survival with osimertinib.
  • Comparison of tissue-based and plasma-based molecular testing was also carried out in the FLAURA trial. The concordance between tissue- and plasma-based testing was 87% for the exon 19 deletion and 88% for the exon 21 L858R point mutation.
