چکیده

Several novel therapeutics are poised to change the natural history of chronic lymphocytic leukaemia (CLL) and the increasing use of these therapies has highlighted limitations of traditional disease monitoring methods. Here we demonstrate that circulating tumour DNA (ctDNA) is readily detectable in patients with CLL. Importantly, ctDNA does not simply mirror the genomic information contained within circulating malignant lymphocytes but instead parallels changes across different disease compartments following treatment with novel therapies. Serial ctDNA analysis allows clonal dynamics to be monitored over time and identifies the emergence of genomic changes associated with Richter's syndrome (RS). In addition to conventional disease monitoring, ctDNA provides a unique opportunity for non-invasive serial analysis of CLL for molecular disease monitoring.

Multifocal clonal evolution characterized using circulating tumour DNA in a case of metastatic breast cancer

Circulating tumour DNA analysis can be used to track tumour burden and analyse cancer genomes non-invasively but the extent to which it represents metastatic heterogeneity is unknown. Here we follow a patient with metastatic ER-positive and HER2-positive breast cancer receiving two lines of targeted therapy over 3 years. We characterize genomic architecture and infer clonal evolution in eight t...

Monitoring chronic lymphocytic leukaemia progression by whole genome sequencing reveals heterogeneous clonal evolution patterns Short Title: longitudinal whole genome sequencing in CLL

Chronic lymphocytic leukaemia (CLL) is characterized by relapse after treatment and chemotherapy resistance. Like in other malignancies, leukaemia cells accumulate mutations during growth, forming heterogeneous cell populations that are subject to Darwinian selection and may respond differentially to treatment. There is therefore a clinical need to monitor changes in the subclonal composition o...

Chromosomes and transformation of lymphocytes in lymphoproliferative disorders.

In chronic lymphocytic leukaemia the majority of circulating lymphocytes which responded to phytohaemagglutinin in vitro were found to have normal karyotypes. A minor population of cells in patients treated with chemotherapy had an increased number of chromosomal rearrangements as compared with cells from normal controls and untreated patients with chronic lymphocytic leukaemia. Probably bonema...

Tumour lysis syndrome after treatment of chronic lymphocytic leukaemia with fludarabine.

Fludarabine is one of the most recent and promising therapeutic agents for chronic lymphocytic leukaemia. We describe a patient who developed tumour lysis syndrome after the first course of treatment with fludarabine and call attention to this uncommon but potentially lethal complication that has not been previously taken into account in this neoplasia. It should always be anticipated when pati...

State of the art in circulating miR-95 as a new candidate for diagnostic in Human Chronic Lymphocytic Leukemia

 Backgrounds: MicroRNAs (miRNAs) have crucial roles in cellular and molecular processes related to different malignancies including chronic lymphocytic leukemia (CLL). In recent years the most studies demonstrated that the expression of miR-95, alter in several diseases. Long non-coding RNAs (lncRNAs) a heterogeneous group of non-coding and regulatory RNAs. The present study investigated the as...
