INTRODUCTION Adenocarcinoma is the most common histologic type of lung cancer. To address advances in oncology, molecular biology, pathology, radiology, and surgery of lung adenocarcinoma, an international multidisciplinary classification was sponsored by the International Association for the Study of Lung Cancer, American Thoracic Society, and European(More)
The global gene expression profiles for 67 human lung tumors representing 56 patients were examined by using 24,000-element cDNA microarrays. Subdivision of the tumors based on gene expression patterns faithfully recapitulated morphological classification of the tumors into squamous, large cell, small cell, and adenocarcinoma. The gene expression patterns(More)
Lung cancer remains one of the leading causes of cancer-related death in developed countries. Although lung adenocarcinomas with EGFR mutations or EML4-ALK fusions respond to treatment by epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) inhibition, respectively, squamous cell lung cancer currently lacks therapeutically(More)
Small-cell lung cancer (SCLC) is an aggressive lung tumor subtype with poor prognosis. We sequenced 29 SCLC exomes, 2 genomes and 15 transcriptomes and found an extremely high mutation rate of 7.4±1 protein-changing mutations per million base pairs. Therefore, we conducted integrated analyses of the various data sets to identify pathogenetically relevant(More)
Comparative genomic hybridization was used to screen 25 adenocarcinomas and 25 squamous cell carcinomas of the lung for chromosomal imbalances. DNA copy number decreases common to both entities were observed on chromosomes 1p, 3p, 4q, 5q, 6q, 8p, 9p, 13q, 18q, and 21q. Similarly, DNA gains were observed for chromosomes 5p, 8q, 11q13, 16p, 17q, and 19q.(More)
HPV has been identified not only in gynaecological carcinomas but also in tumors of other organs, especially of the oropharynx and upper aero-digestive tract. In this study we focused on the available literature on HPV in lung carcinomas. In total, 53 publications reporting on 4508 cases were reviewed and assessed for the following parameters: continent and(More)
S100 proteins form a growing subfamily of proteins related by Ca2+-binding motifs to the Efhand Ca2+-binding protein superfamily. By analyzing a human lung cancer cell line subtraction cDNA library, we have identified and characterized a new member of the human S100 family that we named S100A14 (GenBank acc. no. NM_020672). It encodes a mRNA present in(More)
Lung cancer is a leading cause of cancer death, where the amplification of oncogenes contributes to tumorigenesis. Genomic profiling of 128 lung cancer cell lines and tumors revealed frequent focal DNA amplification at cytoband 14q13.3, a locus not amplified in other tumor types. The smallest region of recurrent amplification spanned the homeobox(More)
UNLABELLED While genomically targeted therapies have improved outcomes for patients with lung adenocarcinoma, little is known about the genomic alterations which drive squamous cell lung cancer. Sanger sequencing of the tyrosine kinome identified mutations in the DDR2 kinase gene in 3.8% of squamous cell lung cancers and cell lines. Squamous lung cancer(More)
The following is a proposition for a simple histopathological classification system to measure inflammation in synovial tissue. This synovitis-score is employed in conventionally stained routine sections, and is applicable to every kind of synovitis, irrespective of etiology and including the following relevant morphological alterations. First:(More)
