Abstract:
:Although targeted deep sequencing of cell-free DNA (cfDNA) was recently used to investigate tumor somatic mutations in particular subtypes of non-Hodgkin lymphomas (NHLs), the immense genetic heterogeneity across subtypes poses a hurdle to design a universal gene panel applicable for diverse subtypes of NHLs. We designed a panel targeting 66 genes associated with NHLs and performed targeted deep sequencing to analyze plasma cfDNA from patients with various subtypes of NHLs. Genetic profiling in plasma cfDNA using the method resulted in 88.0% sensitivity and >99% specificity in detecting mutations present at a frequency greater than 20% in the tumor biopsies. Furthermore, the level of ctDNA significantly decreased and increased depending on designated clinical responses to therapy and disease progression. These results demonstrated that ctDNA sensitively indicated the presence of cancer and reliably correlated with tumor burden, suggesting potential utility of the method for patients with various subtypes of NHLs.
