Abstract

Molecular testing is extremely important in cancer care, starting as early as at diagnosis. In order to address the challenge of providing reliable results within the timeframe adapted to patient management and suitable to guide clinical decisions, a capture‑based next‑generation sequencing (NGS) panel focusing on ten genes known to harbor genetic variations which may be targeted by approved drugs in patients with cancer was designed and validated. Very favorable analytical performances were obtained for both solid and liquid biopsies. For solid biopsies, a low read depth (80X per nucleotide) led to the genotype detection accuracy of 100%. The read of raw data for liquid biopsies resulted in the 91.19% result concordance between paired solid and liquid samples. The present method met all the requirements for the ISO15189 certification. During our three‑year experience of routinely using this panel, almost 2,300 samples from lung and colorectal cancers, melanomas and gastrointestinal stromal tumors have been analyzed. It was found that our panel detected slightly more gain‑of‑function variants than described in the literature. Surprisingly, loss‑of‑function variants were also detected in certain of the analyzed genes. Finally, liquid biopsy data revealed statistically different mutated allele frequencies between tumor types, but also between mutated genes and variants themselves. In conclusion, the use of our capture‑based NGS panel is perfectly adapted to perform relevant molecular diagnosis in a time frame compatible with patient care.
