• Personalized ctDNA detection and genomic profiling in the NeoRHEA Study

  In the management of early hormone receptor (HR)+, HER2-negative breast cancer, circulating tumor DNA (ctDNA) detection is an evolving yet promising diagnostic approach. We evaluated ctDNA detection using the personalized RaDaR assay in plasma samples from patients enrolled in the NeoRHEA clinical trial (NCT03065621), a single-arm, phase II study of neoadjuvant palbociclib and endocrine therapy administered over 4 months (four 28‑day cycles). Plasma samples were collected pre-treatment, after the first treatment cycle, prior to surgery, and one month post-surgery. At baseline, ctDNA positivity was detected in 55% of patients; however, this dropped to 5% during treatment and ctDNA became undetectable in all patients by one month post-surgery. CtDNA detection at baseline was higher in histological grade 3 tumors, lower in multifocal/multicentric tumors and higher in residual cancer burden (RCB) 3 tumors. Genomic analysis revealed MYC gene gains or amplifications were more frequent in ultrasound (US) responders, while PIK3CA gains were more common in US non-responders. Additionally, FAT1 losses were more frequently observed in patients with RCB 3. Our findings suggest that baseline ctDNA presence predicts poor response to neoadjuvant palbociclib and endocrine therapy, underscoring its potential as a biomarker to guide tailored therapeutic approaches in HR+/HER2-negative breast cancer.

• Personalized ctDNA Monitoring and Matched Tumor–Normal Whole-Exome Sequencing in Early HR+/HER2− Breast Cancer

  The dataset comprises whole-exome sequencing (WES) data generated from 160 samples, corresponding to matched tumor–normal pairs from breast cancer patients. For each subject, one tumor biopsy sample and one matched white blood cell (WBC) sample (germline control) are included. Sequencing data are provided as aligned BAM files with corresponding BAI index files. The data were generated using Illumina paired-end sequencing technology following hybrid-capture exome enrichment. The matched tumor–normal design enables accurate identification of somatic variants by filtering germline alterations, supporting downstream analyses such as mutation profiling, biomarker discovery, and personalized circulating tumor DNA (ctDNA) assay development.

• Plasma CTCF ChIP-seq Reveals Cancer-Associated cfDNA Binding Profiles

  Cell-free DNA (cfDNA) in plasma predominantly exists as nucleoprotein complexes. Although circulating CTCF-bound cfDNA (cfCTCF-DNA) has previously been reported, the occupancy of individual CTCF binding sites in plasma has not been systematically characterised. This study describes the isolation of endogenous plasma cfCTCF-DNA by chromatin immunoprecipitation followed by next-generation sequencing (ChIP-seq) in samples obtained from cancer patients and healthy individuals. A two-step enrichment strategy was employed, combining physical removal of background cfDNA by immunoprecipitation with bioinformatic filtering to remove residual non-CTCF-derived sequences. Sequencing reads were aligned to the UCSC hg38 reference genome using BWA-MEM v0.7.17 and processed to generate CRAM files containing alignments restricted to the primary chromosomes (chr1–chr22, chrX, chrY and chrM). CTCF-associated cfDNA fragments were classified according to their similarity to a consensus CTCF binding motif, enabling discrimination between low-affinity and high-affinity CTCF binding sites. Comparative analyses identified quantitative and qualitative differences in plasma cfCTCF-DNA profiles between healthy individuals and patients with cancer. The deposited dataset comprises plasma cfCTCF-DNA ChIP-seq data from four clinical cohorts and includes both CTCF-enriched and total cfDNA samples where applicable. These data support the investigation of CTCF occupancy patterns as a novel class of liquid biopsy biomarkers for cancer detection and monitoring.

• Multi-omic signatures in multiple myeloma

  Multiple myeloma (MM) is a genetically and clinically heterogeneous plasma-cell malignancy. Quadruplet therapy, combining anti-CD38 antibodies, immunomodulatory drugs, proteasome inhibitors, and dexamethasone, is now the standard induction treatment for newly diagnosed multiple myeloma (NDMM). To gain a comprehensive view of molecular changes in MM and their association with treatment response in this new standard care, we performed a multi-omic study of 423 NDMM from the MIDAS trial.

• The evolving genomic landscape of circulating tumor DNA represents an early predictor of immunotherapy response in lung cancer

  Circulating tumor DNA (ctDNA) analyses are informative as an early indicator of immunotherapy response in advanced non-small cell lung cancer (NSCLC), however the clinical role of ctDNA molecular response requires further validation. As part of a prospective clinical protocol (NCT05995821), we performed ctDNA (n=328) and matched white blood cell DNA (WBC; n=109) targeted error-correction sequencing from 109 patients with advanced/metastatic NSCLC who received anti-PD-(L)1 as monotherapy or in combination. Following variant cellular origin resolution, landmark molecular response (mR) was defined as undetectable ctDNA within 3-9 weeks of treatment initiation. Among 2,818 plasma variants, 23% were clonal haematopoiesis-related, which confounded driver gene associations with clinical outcomes and molecular responses. Implementing a tumor-naïve WBC DNA-informed approach increased the number of evaluable cases while maintaining the overall accuracy of landmark ctDNA molecular responses. Pre-treatment ctDNA burden but not blood tumor mutation burden predicted survival. A significant enrichment in landmark ctDNA mR was noted among patients with progression-free survival (PFS) ≥6 months with immunotherapy (p=2.5e-05) and chemo-immunotherapy (p=0.02). Patients in the landmark mR group attained longer progression-free (p=1.6e-06) and overall survival (p=2.5e-05) compared to those with molecular progression. Our findings indicate that landmark ctDNA molecular response provides a real-time and accurate approach for monitoring immunotherapy clinical outcomes. Although not currently validated for regulatory use, these findings demonstrate the potential utility of ctDNA as an early endpoint in clinical trials.

• Serafini et al., Nuclear localization of the glutaminyl-tRNA synthetase QARS reveals its role in DNA damage response in ovarian cancer

  Uncovering novel mechanisms controlling DNA damage response (DDR) is essential to better understand the molecular features of high-grade serous ovarian cancers (HGSOC), which remain a clinical challenge. Here, we demonstrate that the glutaminyl-tRNA-synthetase QARS is a new key player in DDR. We show that QARS is regulated at translational level by the MAPK pathway in HGSOC and controls homologous recombination (HR) through a translation-independent mechanism. Analyses combining RNA sequencing, immunohistochemistry, proteomic data and functional assays from HGSOC patient cohorts and relevant cellular models reveal that QARS promotes DNA repair via the HR pathway. Interestingly, we uncover that QARS is located in the nucleus and is enriched at chromatin upon DNA damage. Nuclear QARS controls HR by interacting with the nuclear autoantigen SP100, a major component of PML-nuclear bodies (PML-NB), that are regulatory hubs for DNA repair proteins. Our data highlight novel nuclear functions and mechanisms for QARS involving SP100, PML-NB and MRE11 that enhance HR in HGSOC.

• RAIDs cervical cancer project

  The RAIDS project, launched by the Curie Institute in 2013, aims to molecularly characterize cervical cancer (CC) and improve patient risk stratification. As part of the Bio-RAIDS study (NCT02428842), next-generation sequencing was performed on tumor samples (whole-exome sequencing, shallow whole-genome sequencing and RNA-sequencing) identified frequent alterations, including PIK3CA (30%) and prognostic biomarkers like TERT, linked to poor progression-free survival. Over 50 clinically targetable mutations were found, offering new therapeutic opportunities. Transcriptomic analysis also linked specific genes and pathways to prognosis and tumor necrosis.
