  • Publication number: 20240336975
    Abstract: The invention relates to methods of breast tumor analysis relying on the detection of expression levels of specific genes. Such methods find application in, amongst other, predicting the response of a breast cancer patient to immunotherapy or to immunogenic therapy, and in following up such responses. The expression levels of the genes can thus be used in determining which breast cancer patients are most likely to respond to immunotherapy or immunogenic therapy. The genes serving as biomarkers are individually highly performant in predicting the response of a breast tumor to immunotherapy or to immunogenic therapy, but are weak in predicting the response of melanoma to immunotherapy or to immunogenic therapy. Diagnostic kits are likewise part of the invention.

  • Patent number: 11814688
    Abstract: The present application relates to the field of cancer, particular to hypoxic tumors. It was found that hypoxia is an important driver for hypermethylation of (promoters of) tumor suppressor genes. As this hypermethylation is a stable signature that is also present in circulating tumor DNA in peripheral blood, detecting this methylation pattern is a surrogate marker for tumor hypoxia. This can be used to adapt therapy as well.

  • Publication number: 20230220446
    Abstract: The field of the invention generally relates to cancer, including methods for diagnosing, prognosing, and treating cancer. In particular, the field of the invention relates to novel signatures of unique sets of point mutations involving a change of a cytosine or a guanidine, and methods, systems, and components thereof based upon the novel signature for identifying tumor samples having increased tumor mutational burden (TMB). Both the signatures and the methods, systems, and components thereof may be utilized for identifying cancer patients, microsatellite stable-cancer patients in particular, who will effectively respond to immune checkpoint blockade therapy.

  • Publication number: 20230042332
    Abstract: Described are methods of analyzing cell free DNA based on combining analysis of cfDNA methylation with analysis of the cfDNA nucleosome footprint and/or with analysis of cfDNA copy number alteration. The diagnostic performance of these methods, in particular relating to early or earlier stage diseases or disorders, is increased compared to the diagnostic performance of the individual cfDNA analysis methods.

  • Publication number: 20220333198
    Abstract: The present invention relates to biomarkers for predicting the risk of developing chronic allograft injury in a patient, and means and methods for (post-transplant) preservation of allografts and transplantation organs. In particular, a method to predict the risk of developing chronic allograft injury in a patient is presented based on age-related increase of methylation of CpGs. In particular, the allograft is a kidney.

  • Publication number: 20220090209
    Abstract: The invention relates to methods of tumor analysis relying on the detection of expression of or of changes in the expression levels of specific retrotransposons. Such methods find application in, amongst other, predicting the response of a tumor to immunotherapy or to immunogenic therapy, and in following up such responses. The expression levels of specific retrotransposons can thus be used in determining which patients are most likely to respond to immunotherapy or immunogenic therapy. Corresponding diagnostic kits are likewise part of the invention.

  • Patent number: 11208461

  • Publication number: 20210388441
    Abstract: The present invention relates to the identification of a specific set of CpG biomarkers for predicting the risk of developing chronic allograft injury in a patient, and means and methods for preservation of allografts and transplantation organs. In particular, a method to predict the risk of developing chronic allograft injury in a patient is presented based on cold-ischemia induced hypermethylation of CpGs as an important driver for downregulation of (promoters of) genes essential for organ preservation. Specifically, a CpG biomarker signature for hypermethylation of renal allograft organs caused by hypoxia and ischemia pre-implantation revealed treatment options of ischemia-associated chronic allograft injury and preservation of donor kidneys.
