Question 1/4
According to the 2020 NCCN Guidelines for NSCLC, which biomarkers have FDA-approved targeted agents available and should therefore be tested?
Correct

The 2020 NCCN guidelines for NSCLC recommend testing for ALK rearrangements, ROS1 rearrangements, EGFR mutations, BRAF mutations, MET exon 14 skipping mutations, RET rearrangements and PD-L1 expression levels because FDA-approved agents are available for these biomarkers.

Testing for other genetic variants may also be done – such as NTRK, MET amplification and HER2 mutations to identify these rare oncogenic driver variants for which effective therapy may be available, although there is less evidence to support testing.

Abbreviations
ALK, anaplastic lymphoma kinase; EGFR, epidermal growth factor receptor; FDA, US Food and Drug Administration; HER2, human epidermal growth factor receptor 2; METex14, mesenchymal–epithelial transition exon 14; NCCN, National Comprehensive Cancer Network; NSCLC, non-small-cell lung carcinoma; NTRK, neurotrophic tropomyosin receptor kinase; PD-L1, programmed death-ligand 1; PIK3CA, phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha; RET, rearranged during transfection.

Question 2/4
Approximately what proportion of patients with NSCLC and the adenocarcinoma histologic subtype have METex14 skipping mutations?
Correct

METex14 skipping mutations occur in 3–4% of patients with adenocarcinoma and 1–2% of patients with other NSCLC histologies. MET skipping mutations are more frequent in older women who are non-smokers.

Abbreviations
MET, mesenchymal–epithelial transition, NSCLC, non-small-cell lung carcinoma; NGS, next-generation sequencing; PCR, polymerase chain reaction.

Question 3/4
Why might ctDNA testing (liquid biopsy) be especially helpful in identifying tumor mutations in NSCLC?
Correct

In NSCLC tumor biomarker testing, liquid biopsy is noninvasive and easily repeatable over time, and captures systemic tumor burden, which may be more complete than single-site sampling that may be affected by tumor heterogeneity.1,2

Tissue biopsy is the historical standard for biomarker identification, and has higher sensitivity, but serial sample collection can be too burdensome for the patient to be feasible.1,2

Abbreviations
ctDNA, circulating tumor DNA; NSCLC, non-small-cell lung carcinoma

Question 4/4
In which clinical circumstances would you specifically consider using ctDNA testing (liquid biopsy) in NSCLC?
Correct

NCCN guidelines state that ctDNA testing should not be used in lieu of histologic tissue diagnosis. ctDNA generally has a very high specificity, but low sensitivity with up to 30% false-negative rate. In addition, standards for analytical performance for ctDNA have not yet been established.1

Liquid biopsy offers an alternative to standard procedures when tissue biopsy specimens are insufficient or unfeasible.2
