Abstract: Methods of using probes and probe sets for the detection of high grade dysplasia and carcinoma in cervical cells are described. Methods of the invention include hybridizing one or more chromosomal probes to a biological sample obtained from a subject and detecting the hybridization pattern of the chromosomal probes to the sample to determine whether the subject has high grade dysplasia or carcinoma. Methods of the invention also include preliminary screening the cells for a marker associated with a risk for cancer, and preferably involves screening for HPV infected cells by in situ hybridization using an HPV probe mixture.

Abstract: Methods, compositions and kits for screening for the presence of Epidermal Growth Factor Receptor variant 3 (EGFR(v3)) in a sample are disclosed. The method comprises obtaining a sample containing a plurality of cells; hybridizing a set of chromosomal probes to the sample, wherein the set comprises an EGFR(v3)-probe and a probe to chromosome 7 different from an EGFR(v3)-probe; and visualizing the hybridization pattern of the set of chromosomal probes in the plurality of cells of the sample, wherein the presence of at least one copy of chromosome 7 lacking a hybridization signal of the EGFR(v3)-probe in at least one cell is indicative of the presence of the EGFR(v3) in the sample. The methods, compositions and kits are suitable for diagnosing the therapeutic outcome for treating a patient having a cancer with an anti-EGFR therapeutic agent and for screening a sample for a predisposition for forming an EGFR-associated cancer.

Abstract: Methods of screening a sample for a predisposition for forming an EGFR-associated cancer and the presence of EGFR (v3) contained therein are described. The methods include the steps of obtaining a sample containing a plurality of cells and hybridizing a first set of labeled chromosomal probes and a second set of labeled chromosomal probes to the sample. The first set of labeled chromosomal probes specific to chromosome 7, and the second set of labeled chromosomal probes is a labeled EGFR(v3)-probe. The first and second sets of labeled chromosomal probes include different labels to permit identification of the first and second sets of labeled chromosomal probes hybridized to the sample. The method includes calculating the number of signals of the first and second sets labeled chromosomal probes on an individual cell basis and determining a predisposition for forming an EGFR-associated cancer and the presence of EGFR (v3) contained therein based upon those calculations.

Abstract: The invention provides methods for identifying early stage non-small cell lung cancer (NSCLC) patients who will have a favorable prognosis for the recurrence of lung cancer after surgical resection. The invention is based on the discovery that assessment of chromosomal copy number abnormalities at two or more of chromosome 5p15, 7p12, 8q24 and centromere 6 can be used for prognostic classification. The invention preferably uses fluorescence in situ hybridization with fluorescently labeled nucleic acid probes to hybridize to patient samples to quantify the chromosomal copy number of the these genetic loci.

Abstract: The invention provides methods for identifying early stage non-small cell lung cancer (NSCLC) patients who will have a favorable prognosis for the recurrence of lung cancer after surgical resection. The invention is based on the discovery that assessment of chromosomal copy number abnormalities at chromosome 10q23.3 and centromere 10 can be used for prognostic classification. The invention preferably uses fluorescence in situ hybridization with fluorescently labeled nucleic acid probes to hybridize to patient samples to quantify the chromosomal copy number of the these genetic loci. The chromosome copy number can also be determined using, for example, PCR or array CGH. Assessment of the copy number abnormality patterns with a classifier based on the relative loss of 10q23.3 signals compared to the centromere 10 signals produced statistically significant prognostic classification for NSCLC. The ratio of PTEN/CEP 10 signals, using a cutoff of 0.80, was capable of dividing patients into a group of 41 (?0.
