The analyzed study group is relatively small and differences of MYC and TERT detection rates in comparison to other studies are based on different group sizes, ranging from 21 [18] to 2,032 lung cancer cases [35], and different methods for the detection of CNV, dPCR [7, 32], quantitative PCR (qPCR) [9, 19], and whole genome sequencing (WGS) [2, 23, 36]. This evidence concerns the gene TERT and lung cancer.
