INTRODUCTION
Non-small cell lung cancer (NSCLC) is an important
cause of morbidity and mortality worldwide. Many patients
with NSCLS are diagnosed at advanced stages and treated
with targeted therapy and immunotherapy in addition to
systemic chemotherapy [1]. The College of American Pathologists
(CAP), International Association for the Study
of Lung Cancer (IASLC) and Association for Molecular
Pathology (AMP) recommended that EGFR, ALK, and
ROS1 were necessary tests in advanced stage NSCLC patients
whose tumors contain an element of adenocarcinoma
(AC) in their 2018 updated testing guideline. Moreover,
the results of the recent clinical data indicate those panels
including BRAF, MET, RET, ERBB2 and KRAS, should be
used at a minimum [2]. Cell-free circulating tumor DNA
(ccfDNA), which is released from the tumor into the systemic
circulation, is used in the liquid biopsy [3].
Thompson et al. [4] and Schwaederlé et al. [5] demonstrated
that next generation sequencing (NGS) of plasmabased
ccfDNA can be used to assess mutations in NSCLC.
Several recent retrospective and prospective studies also
used plasma samples to decide targeted treatments [6,7].
The NGS used for the analysis of ccfDNA involves reading
of the DNA strand 10,000-times using deep sequencing
and allows determination of the type and frequency of a given mutation by bioinformatic analyses. It is possible to
identify single base mutations, short insertions and deletions,
wide genomic deletions, or rearrangements such as
inversion and translocation (by amplifications) using NGS
[8]. In the present study, we aimed to present our NGS
results of liquid biopsy samples that is increasingly used in
clinical practice for NSCLC that comprises several genetic
alterations guiding therapeutic opportunities.
