Abstract |
Recent genetic studies identified that the disease-specific G17V RHOA mutation, together with mutations in TET2, DNMT3A, and IDH2, is a hallmark of angioimmunoblastic T cell lymphomas (AITL). The diagnostic value of these mutations is now being investigated. Circulating tumor DNAs (ctDNAs) may offer a non-invasive testing for diagnosis and disease monitoring of cancers. To investigate whether these mutations are useful markers for ctDNAs in AITL and its related lymphomas, we performed targeted sequencing for TET2, RHOA, DNMT3A, and IDH2 in paired tumors and cell-free DNAs from 14 patients at diagnosis. Eighty-three percent of mutations detected in tumors were also observed in cell-free DNAs. During the disease course, mutations were detectable in cell-free DNAs in a refractory case, while they disappeared in a chemosensitive case. These data suggest that the disease-specific gene mutations serve as sensitive indicators for ctDNAs and may also be applicable for non-invasive monitoring of minimal residual diseases in AITL. |
