    Pan-cancer analysis of whole genomes

    Cancer is driven by genetic change, and the advent of massively parallel sequencing has enabled systematic documentation of this variation at the whole-genome scale(1-3). Here we report the integrative analysis of 2,658 whole-cancer genomes and their matching normal tissues across 38 tumour types from the Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium of the International Cancer Genome Consortium (ICGC) and The Cancer Genome Atlas (TCGA). We describe the generation of the PCAWG resource, facilitated by international data sharing using compute clouds. On average, cancer genomes contained 4-5 driver mutations when combining coding and non-coding genomic elements; however, in around 5% of cases no drivers were identified, suggesting that cancer driver discovery is not yet complete. Chromothripsis, in which many clustered structural variants arise in a single catastrophic event, is frequently an early event in tumour evolution; in acral melanoma, for example, these events precede most somatic point mutations and affect several cancer-associated genes simultaneously. Cancers with abnormal telomere maintenance often originate from tissues with low replicative activity and show several mechanisms of preventing telomere attrition to critical levels. Common and rare germline variants affect patterns of somatic mutation, including point mutations, structural variants and somatic retrotransposition. A collection of papers from the PCAWG Consortium describes non-coding mutations that drive cancer beyond those in the TERT promoter(4); identifies new signatures of mutational processes that cause base substitutions, small insertions and deletions and structural variation(5,6); analyses timings and patterns of tumour evolution(7); describes the diverse transcriptional consequences of somatic mutation on splicing, expression levels, fusion genes and promoter activity(8,9); and evaluates a range of more-specialized features of cancer genomes(8,10-18).Peer reviewe

    © 2021 John Wiley & Sons. This is the accepted manuscript version of an article which has been published in final form at https://doi.org/10.1002/pdi.2368The aim of the audit was to assess the change in key health markers in people with, or at risk of, diabetes who attended X-PERT structured diabetes education. Data from X-PERT programmes are entered into a central database. Twelve-month changes in anthropometric and clinical variables – and diabetes medication usage – are reported for programmes run between 1 January 2017 and 31 December 2018. Where appropriate, paired t-tests were performed. In total, 29,703 participants were registered to attend a programme during this period, of which 23,118 (78%) attended at least one session. Of those who attended at least one session18,039 (78%) completed a programme. Ninety-nine percent (3342) of participants with clinical data available had type 2 diabetes. Meaningful reductions in HbA1c were seen (-8.6mmol/mol,95% CI -9.2 to -8.0mmol/mol [-0.8%, 95% CI -0.8 to -0.7%]; n=2957; p<0.001); and there were statistically significant reductions in body weight, BMI, waist circumference, fasting blood glucose, total cholesterol, low-density lipoprotein cholesterol, triglycerides, total cholesterol to high-density lipoprotein cholesterol ratio, and triglycerides to high-density lipoprotein cholesterol ratio (all p<0.001). No change in high-density lipoprotein cholesterol was observed. Of the 1180 participants who were recorded as taking diabetes medication at baseline, 632(54%) were able to reduce the number of medications they were taking and 278 (24%) were able to omit them entirely. Participant empowerment score increased by 20%. Improvements in glycaemic control, weight management and cardiovascular disease risk, as well as reduced medication requirements and an increased feeling of empowerment, were observed in people who attended X-PERT structured diabetes education programmes.Peer reviewe
