Circulating tumour DNA sequencing to determine therapeutic response and identify tumour heterogeneity in patients with paediatric solid tumours.
(ELSEVIER SCI LTD, 2021-12-18)OBJECTIVE: Clinical diagnostic sequencing of circulating tumour DNA (ctDNA) is well advanced for adult patients, but application to paediatric cancer patients lags behind. METHODS: To address this, we have developed a ... -
Circulating Tumour DNAs and Non-Coding RNAs as Liquid Biopsies for the Management of Colorectal Cancer Patients
(MDPI, 2020-09-01)<jats:p>Circulating tumour DNAs and non-coding RNAs present in body fluids have been under investigation as tools for cancer diagnosis, disease monitoring, and prognosis for many years. These so-called liquid biopsies offer ... -
Class(y) Dissection of BRAF Heterogeneity: Beyond Non-V600.
(AMER ASSOC CANCER RESEARCH, 2019-12-01)Different classes of BRAF mutations are present in colorectal and other cancers. Non-V600 mutations are rare; however, their detection rate will increase as the use of next-generation sequencing ramps up quickly in clinical ... -
Classifying the evolutionary and ecological features of neoplasms.
(NATURE PUBLISHING GROUP, 2017-10-01)Neoplasms change over time through a process of cell-level evolution, driven by genetic and epigenetic alterations. However, the ecology of the microenvironment of a neoplastic cell determines which changes provide adaptive ... -
Claudin-18 expression in oesophagogastric adenocarcinomas: a tissue microarray study of 523 molecularly profiled cases.
(NATURE PUBLISHING GROUP, 2019-07-30)BACKGROUND: Claudin-18 (CLDN18) is a highly specific tight junction protein of the gastric mucosa. An isoform of CLDN18, the Claudin 18.2, has recently emerged as an innovative drug target for metastatic gastric cancer. ... -
Clinical and co-clinical genomics of paediatric solid tumours with a special focus in DIPG
(Institute of Cancer Research (University Of London), 2020-07-31)Cure rates for paediatric solid cancers have not improved in the last decade. Delivering precision medicine to stratify patients based on their molecular profiling is a key goal to support existing and upcoming adaptive ... -
Clinical and Molecular Spectrum of Liposarcoma.
(LIPPINCOTT WILLIAMS & WILKINS, 2018-01-10)Liposarcomas are rare malignant tumors of adipocytic differentiation. The classification of liposarcomas into four principal subtypes reflects the distinct clinical behavior, treatment sensitivity, and underlying biology ... -
Clinical BRCA1/2 Reversion Analysis Identifies Hotspot Mutations and Predicted Neoantigens Associated with Therapy Resistance.
(AMER ASSOC CANCER RESEARCH, 2020-10-01)Reversion mutations in BRCA1 or BRCA2 are associated with resistance to PARP inhibitors and platinum. To better understand the nature of these mutations, we collated, codified, and analyzed more than 300 reversions. This ... -
Clinical impact of subclonal EGFR T790M mutations in advanced-stage EGFR-mutant non-small-cell lung cancers.
(2021-03-19)Advanced non-small-cell lung cancer (NSCLC) patients with EGFR T790M-positive tumours benefit from osimertinib, an epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI). Here we show that the size of the ... -
Clinical management and outcomes of primary ovarian leiomyosarcoma - Experience from a sarcoma specialist unit.
(ELSEVIER SCIENCE INC, 2021-03-01)Ovarian sarcomas account for 1% of all ovarian malignancies and amongst these, primary ovarian leiomyosarcoma is the rarest subtype. Primary ovarian leiomyosarcoma has a very poor prognosis, with less than 20% of patients ... -
Clinical outcomes of COVID-19 in long-term care facilities for people with epilepsy.
In this cohort study, we aim to compare outcomes from coronavirus disease 2019 (COVID-19) in people with severe epilepsy and other co-morbidities living in long-term care facilities which all implemented early preventative ... -
Clinical significance of DNA methylation in chronic lymphocytic leukemia patients: results from 3 UK clinical trials
(American Society of Hematology, 2019-08-27)<jats:title>Abstract</jats:title><jats:p>Chronic lymphocytic leukemia patients with mutated immunoglobulin heavy-chain genes (IGHV-M), particularly those lacking poor-risk genomic lesions, often respond well to chemoimmunotherapy ... -
Clinical validity of clinical treatment score 5 (CTS5) for estimating risk of late recurrence in unselected, non-trial patients with early oestrogen receptor-positive breast cancer.
(SPRINGER, 2020-11-21)PURPOSE: Clinical Treatment Score at 5 years (CTS5) is a prognostic tool to estimate distant recurrence (DR) risk after 5 years of endocrine therapy for postmenopausal women with oestrogen receptor-positive (ER-positive) ... -
