Abstract

BACKGROUND:

Gene fusion events resulting from chromosomal rearrangements play an important role in initiation of lung adenocarcinoma. The recent association of four oncogenic driver genes, ALK, ROS1, RET, and NTRK1, as lung tumor predictive biomarkers has increased the need for development of up-to-date technologies for detection of these biomarkers in limited amounts of material.

METHODS:

We describe here a multi-institutional study using the Ion AmpliSeq™ RNA Fusion Lung Cancer Research Panel to interrogate previously characterized lung tumor samples.

RESULTS:

Reproducibility between laboratories using diluted fusion-positive cell lines was 100%. A cohort of lung clinical research samples from different origins (tissue biopsies, tissue resections, lymph nodes and pleural fluid samples) were used to evaluate the panel. We observed 97% concordance for ALK (28/30 positive; 71/70 negative samples), 95% for ROS1 (3/4 positive; 19/18 negative samples), and 93% for RET (2/1 positive; 13/14 negative samples) between the AmpliSeq assay and other methodologies.

CONCLUSION:

This methodology enables simultaneous detection of multiple ALK, ROS1, RET, and NTRK1 gene fusion transcripts in a single panel, enhanced by an integrated analysis solution. The assay performs well on limited amounts of input RNA (10 ng) and offers an integrated single assay solution for detection of actionable fusions in lung adenocarcinoma, with potential savings in both cost and turn-around-time compared to the combination of all four assays by other methods.

This French program is organized by ITMO Cancer, in collaboration with ITMO BCDE (Cell Biology, Development and Evolution) and ITMO Technologies for Health of the National Alliance for Life Sciences and Health (AVIESAN) with the National Cancer Institute (INCA) and Inserm within the framework of the Cancer Plan. Operational management is entrusted to Inserm.
It was launch in order to develop a critical mass of resources and skills in order to conduct interdisciplinary research projects in the field of functional heterogeneity of cellular tumor relations in their ecosystem: the "HTE Program".
