• Non-invasive anal (pre)cancer dataset

  Molecular analysis of DNA from human anal swabs offers a non-invasive method for anal cancer screening. Current guidelines recommend anal swab-based screening and highlight the need for objective biomarkers to improve risk stratification. We performed genome-wide methylation profiling on DNA from 86 anal swab samples, including 40 HSIL-AIN3 cases (high-grade squamous intraepithelial lesions), 39 controls (<=LSIL), and 7 anal cancer patients, using the 850K Infinium MethylationEPIC BeadChip (Illumina). From this analysis, we identified a three-gene methylation classifier that showed strong discriminatory performance in distinguishing HSIL-AIN3 and anal cancer from <=LSIL lesions and successfully identified all anal cancer cases when applied to an independent validation cohort.

• DAC for Early detection of ovarian cancer using cell-free DNA fragmentomes and protein biomarkers

  Ovarian cancer is a leading cause of death from gynecological malignancies worldwide. No effective screening methods exist resulting in tumor detection at advanced stages where treatment is less effective. In this study, we used whole-genome cell-free DNA (cfDNA) fragmentome and protein biomarker (CA-125 and HE4) analyses to evaluate 591 women, mostly post-menopausal, from the European Union or the United States with ovarian cancer, benign adnexal masses, or without ovarian lesions. Using a machine learning model that incorporated multi-analyte fragmentome data and protein measurements, we evaluated the detection of ovarian cancer in two clinical settings, detection of ovarian cancers among a healthy population, and classification of adnexal masses as benign or malignant. The combined approach detected ovarian cancer with specificity >99% and sensitivity of 72%, 69%, 87%, and 100% for stages I–IV, respectively (AUC=0.96, 95% CI: 0.94-0.99), including 90% of high grade serous ovarian cancers. At the same specificity, CA-125 alone detected 34%, 62%, 63%, and 100% of ovarian cancers for stages I–IV (p=0.001, two-sided test of equal proportions). Additionally, our approach differentiated benign masses from ovarian cancers with high accuracy (AUC of 0.88, 95% CI=0.83-0.92). These results were validated in an independent population. These findings show that integrated cfDNA fragmentome and protein analyses detect ovarian cancers with high performance, enabling a new accessible approach for noninvasive ovarian cancer screening and diagnostic evaluation.

• Prefibrotic Bone Marrow Microenvironment is a Hallmark of Clonal Hematopoiesis

  Clonal hematopoiesis of indeterminate potential (CHIP) is linked to systemic inflammation and increased malignant risk, yet its impact on the bone marrow (BM) niche remains poorly understood. Through single-cell transcriptomic profiling of freshly isolated BM, we identify fibro-inflammatory rewiring as an early hallmark of CHIP. Beyond a myeloid-biased inflammatory state, CHIP BM exhibited coordinated TNFα activation across hematopoietic progenitor, monocyte, and stromal compartments. Stromal populations displayed early fibrotic remodeling, with mesenchymal and vascular cells upregulating collagen and extracellular matrix programs. Fibroblasts were markedly expanded independent of mutational subtype and acquired cancer-associated fibroblast (CAF)-like programs, rewiring niche interactions through IL-6, TGFβ, and collagen-integrin signaling. Together, these findings establish fibro-inflammatory BM remodeling as an early hallmark of clonal expansion, linking CHIP to prefibrotic stromal remodeling, immune dysregulation, and a niche architecture consistent with increased malignant risk.

• NICHE - Pre-treatment single cell RNA-seq of MMR proficient early stage colon cancers

  This dataset includes raw single cell RNA sequencing data from 13 pMMR colon cancer patients treated with neoadjuvant immune checkpoint blockade in the NICHE trial. This dataset comprises pre-treatment colon cancer biopsy samples, which digested to obtain single cell suspensions, sorted for CD45+, labelled with hashtag antibodies, split in 3 cell pools, and distributed in 5 sequencing samples (7654_1-5). 30 FASTQ files were generated, 10 files for scRNAseq gene expression (10X Genomics Chromium Next GEM Single Cell 5' v2), 10 files for single cell TCRseq (10X Genomics Chromium Next GEM Single Cell V(D)J Reagent Kits 5' v2) and 10 files for feature barcodes and hashtag antibodies, with feature reference barcodes provided. Samples were sequenced on Illumina Novaseq 6000 and raw FASTQ files were later processed with Cellranger workflows from 10X Genomics, investigating features of pre-treatment immune tumour cells and associations with neoadjuvant response.
