    摘要: Disclosed herein are antibodies having binding specificity to the amino acid sequences Ala Ser Ser Gly Leu Thr Val Glu Val Asp (SEQ ID NO:1) and Thr Val Glu Val Asp (SEQ ID NO:14), and methods of detecting cell death in a sample, comprising contacting the sample with a first antibody specific for a C-terminal amino acid sequence Ala Ser Ser Gly Leu Thr Val Glu Val Asp (SEQ ID NO:1) or Thr Val Glu Val Asp (SEQ ID NO:14) of a CK18 protein fragment having a C-terminal amino acid sequence of Val Glu Val Asp (SEQ ID NO:2) and a second antibody that specifically binds an epitope that is present in both full-length CK18 and the CK18 protein fragment, and that does not overlap with SEQ ID NO:1 or SEQ ID NO:14, under conditions such that the CK18 protein fragment present in the sample specifically binds to the first antibody and the second antibody, wherein one of the antibodies is bound to a solid support and the other antibody is bound to a detection moiety capable of producing a signal; optionally removing any unbound or excess material; and detecting the signal from the detection moiety, wherein the signal is positively correlated with the presence of the CK18 protein fragment in the sample.

    摘要: The present invention relates to an in vitro method for assessing the risk of non-small cell lung carcinoma (NSCLC) disease progression for a subject classified to have stable disease under an ongoing NSCLC treatment regime. The method involves determining the level of CYFRA 21-1 and/or the level of CA 125 in a sample obtained from the subject; and comparing (i) the determined level of CYFRA 21-1 to a CYFRA 21-1 cut-off level, (ii) the determined level of CA 125 to a CA 125 cut-off level, or (iii) a score taking into account the determined level of CYFRA 21-1 and/or the determined level of CA 125 to a cut-off score. The method of the invention further allows for assessing whether the subject responds to the ongoing treatment and/or whether the treatment regime should be maintained or modified. The invention also provides for corresponding uses, computer-implemented methods and computer program products.

    摘要: Provided herein are methods for determining the risk that a subject diagnosed with colorectal cancer will develop a recurrence of colorectal cancer and methods of predicting clinical outcome for a subject diagnosed with colorectal cancer by a) determining the level of expression for each marker of a panel of markers in a panel of tumor compartments in a tumor tissue sample from the subject, wherein the panel of markers comprises at least two of TEM1, HIF2α, CAIX, PDGFRβ, fibronectin, collagen I, collagen IV, and CD31 and wherein the panel of tumor compartments comprises at least three tumor compartments of pure stroma, tumor, stromal vessel, and tumor vessel; b) determining the TAPPS score for said subject; and c) comparing the TAPPS score of the subject to the TAPPS score of a population of subjects diagnosed with colorectal cancer. Also provided are related computer-implemented methods and systems, kits, and tumor microarrays.

    摘要: The disclosure provides methods for detecting circulating endothelial cells (CECs) that mimic CTCs with respect to aspects of their immunofluorescent staining and with respect to aspects of their morphological characteristics (CTC mimics). The present disclosure is based, in part, on the unexpected discovery that CTC mimics can be detected in non-enriched blood samples among CTC candidate cells. The present disclosure is further based, in part, on the discovery that CTC mimics can be detected in non-enriched blood samples by combining the detection of one or more immunofluorescent markers in the nucleated cells of a non-enriched blood sample with an assessment of the morphology of the nucleated cells.
