In this study we analysed patients with metastatic prostate cancer to scan their tumor genomes noninvasively in plasma DNA. We enriched 1.3 Mbp of seven plasma DNAs (4 CRPC cases: CRPC1-3 and CRPC5; 3 CSPC cases: CSPC1-2 and CSPC4) including exonic sequences of 55 cancer genes and 38 introns of 18 genes, where fusion breakpoints have been described using Sure Select Custom DNA Kit.
PPM1D, a central regulator of the DNA damage response, is commonly mutated in therapy-related clonal hematopoiesis (CH), acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS). PPM1D mutations have been shown to expand under selective pressure of DNA-damaging chemotherapy. However, whether PPM1D mutations promote the development of hematologic malignancies remains unclear.

This study aimed to validate the potential utility of a clinically accessible, highly sensitive tumor-informed circulating tumor DNA (ctDNA) assay. The study considers a ‘landmark’ time period (between two weeks and four months after definitive treatment), as well as longitudinal sampling (>2 weeks) and compares two independent, retrospectively collected real-world cohorts.
Prospective biobanking study in SCANDARE HNSCC (Head and Neck Squamous Cell Carcinoma) patients aiming at better understand the link between the molecular alterations of the tumor itself, its microenvironment and immune response.
Prospective biobanking study in ovarian cancer patients aiming at better understand the link between the molecular alterations of the tumor itself, its microenvironment and immune response.
