Although prognostic gene expression signatures for survival in early-stage lung cancer have been proposed, for clinical application, it is critical to establish their performance across different subject populations and in different laboratories. Here we report a large, training-testing, multi-site, blinded validation study to characterize the performance(More)
OBJECTIVE The optimal procedure for resection of malignant pleural mesothelioma is controversial, partly because previous analyses include small numbers of patients. We performed a multi-institutional study to increase statistical power to detect significant differences in outcome between extrapleural pneumonectomy and pleurectomy/decortication. METHODS(More)
Metastasis and chemoresistance in cancer are linked phenomena, but the molecular basis for this link is unknown. We uncovered a network of paracrine signals between carcinoma, myeloid, and endothelial cells that drives both processes in breast cancer. Cancer cells that overexpress CXCL1 and 2 by transcriptional hyperactivation or 4q21 amplification are(More)
OBJECTIVE We examined the effect of radiation on survival for early-stage uterine carcinosarcomas and leiomyosarcomas. STUDY DESIGN The surveillance, epidemiology, and end results database was used to identify patients with stage I/II carcinosarcomas and leiomyosarcomas. Logistic regression and Cox models were developed to determine radiation use and(More)
OBJECTIVE To compare the clinical behavior and outcome of uterine carcinosarcomas and grade 3 endometrioid carcinomas. METHODS Data on patients with grade 3 endometrioid adenocarcinomas and uterine carcinosarcomas, from 1988 to 2004, was obtained from the Surveillance, Epidemiology, and End Results database. Mortality was analyzed using Cox proportional(More)
Large-scale integrated cancer genome characterization efforts including the cancer genome atlas and the cancer cell line encyclopedia have created unprecedented opportunities to study cancer biology in the context of knowing the entire catalog of genetic alterations. A clinically important challenge is to discover cancer subtypes and their molecular drivers(More)
BACKGROUND Lung injury, defined as acute hypoxemia accompanied by radiographic pulmonary infiltrates without a clearly identifiable cause, is a major cause of morbidity and mortality after major anatomic pulmonary resection. Our objective was to identify the incidence and risk factors for the development of postoperative lung injury. METHODS A(More)
MOTIVATION High-throughput techniques facilitate the simultaneous measurement of DNA copy number at hundreds of thousands of sites on a genome. Older techniques allow measurement only of total copy number, the sum of the copy number contributions from the two parental chromosomes. Newer single nucleotide polymorphism (SNP) techniques can in addition enable(More)
The histologic heterogeneity of lung adenocarcinoma creates a variety of complex challenges to pathologists in analyzing the various subtypes. Current classification schemas do not take into account the major subtype. We analyzed 100 cases for clinical, pathologic, and molecular features using a modification of the 2004 World Health Organization (WHO)(More)
We detected clonal mosaicism for large chromosomal anomalies (duplications, deletions and uniparental disomy) using SNP microarray data from over 50,000 subjects recruited for genome-wide association studies. This detection method requires a relatively high frequency of cells with the same abnormal karyotype (>5-10%; presumably of clonal origin) in the(More)
