    • 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. Assessment of the copy number abnormality patterns using four classifiers produced statistically significant prognostic classification for NSCLC: (i) the Range3 pattern of cells showing a difference on a cell by cell basis, of at least three FISH probe signals between the FISH signals at the chromosomal locus with the largest number of FISH signals minus the FISH signals at the chromosomal locus with the lowest number of FISH signals; (ii) the MYC/EGFR % loss pattern assessing the percentage of cells showing fewer MYC FISH probe signals than EGFR FISH probe signals; (iii) a combination of the Range3 pattern and the MYC/CEP6 ratio pattern of a percentage of cells showing a relative loss of MYC FISH probe signals to the FISH probe signal for CEP6; (iv) the combination of the MYC/5p15 ratio pattern showing the relative ratio of MYC and 5p15 locus signals of ≧0.80 and the 5p15/CEP6 ratio pattern assessing percentage of cells having a relative ratio of 5p15 FISH probe signals to CEP6 FISH probe signals ≧1.1 versus MYC/5p15 ratio of

    • Probe sets and methods of using probes and probe sets for selectively detecting high grade dysplasia and esophageal adenocarcinoma or low grade dysplasia from biologic samples are described. Methods of the invention include contacting a biological sample obtained from a subject with a set of chromosomal probes to selectively detect an esophageal carcinoma or precursor lesion in the sample, if any, under conditions for specifically hybridizing the probes to their nucleic targets present in the sample. The presence or absence of high grade dysplasia and esophageal adenocarcinoma or low grade dysplasia is thereafter specifically determined from the hybridization pattern detected for the set of chromosomal probes to the biological sample.
