  • Patent number: 10047403
    Abstract: The present disclosure provides methods for identifying early stage non-small-cell lung cancer (NSCLC) patients who will have an unfavorable prognosis for the recurrence of lung cancer after surgical resection. The methods are based in part on the discovery of chromosomal copy number abnormalities that can be used for prognostic classification. The methods preferably use fluorescence in situ hybridization with fluorescently labeled nucleic acid probes to hybridize to patient samples to quantify the chromosomal copy number of these genetic loci.

  • Publication number: 20120135429
    Abstract: A method for classifying cancer patients as eligible to receive cancer therapy with a Bcl-2 inhibitor comprising determination of the presence or absence in a patient tissue sample of levels of pro-GRP, as a surrogate marker for the presence of chromosomal copy number gain at chromosomal locus 18q21-q22. The classification of cancer patients based upon pro-GRP levels as a surrogate for the presence or absence of 18q21-q22 gain allows selection of patients to receive chemotherapy with a Bcl-2 family inhibitor, either as monotherapy or as part of combination therapy, and to monitor patient response to such therapy using a peripheral blood sample.
