(Submitter supplied) The majority of patients with squamous cell lung cancer (SCC) die because of metastatic disease. The genomic mechanisms underlying this metastatic behaviour are underexposed. We analyzed a cohort of patients with primary squamous cell carcinoma (SCC) using array-based comparative genomic hybridization (aCGH) to identify which genomic aberrations were related metastatic behaviour. The cohort consisted of 34 patients with a follow-up of at least 5 years, including 15 without any metastases, 8 with metastases in regional lymph nodes only, and 11 with metastases exclusively in distant organs within two years after surgery. more...

(Submitter supplied) Chronic obstructive pulmonary disease (COPD) and squamous cell lung carcinoma (SCC) are both smoking-related diseases. Interestingly, COPD itself is a risk factor for SCC, and this is independent of smoking history. Inferring from this knowledge, it is plausible to assume that patients with COPD may have a different gene expression profile in normal bronchial epithelium and in SCC. To test this hypothesis, we compared gene expression profiles in bronchial epithelium and in SCC from patients with and without COPD. more...

(Submitter supplied) PURPOSE: Bone marrow (BM) is a common homing organ for early disseminated tumor cells (DTC) and their presence can predict the subsequent occurrence of overt metastasis and survival in lung cancer. It is still unclear whether the shedding of DTC from the primary tumor is a random process or a selective release driven by a specific genomic pattern. EXPERIMENTAL DESIGN: DTCs were identified in BM from lung cancer patients by an immunocytochemical cytokeratin assay. more...

Sampling was limited to 29 paraffin blocks which could be used up without interference with diagnostic procedures: 8 IDCs, 11 IDCMs and 10 ipsilateral LN metastases [5 to the sentinel LN (first in lymph drainage chain, MS) and 5 to more distal (MD)]. 7 IDCMs had samples of their LN metastases (IDCM9,13, 14, 15, 17, 18, 19). more...

(Submitter supplied) Cigarette smoking is the main risk factor for the development of squamous cell lung carcinoma (SCC). However, the smoking-related molecular changes in SCC have not been studied. We wanted to identify genes in both histologically normal bronchial epithelium and SCC samples that are differentially expressed between current and ex-smokers. In addition, to analyze the levels of the smoking-related genes identified in normal bronchial epithelium with the levels in SCC. more...

(Submitter supplied) We recently identified a subset of down-regulated miRNAs such as miR-145 and miR-133a in squamous cell carcinoma. Cell growth inhibitions occurred in miR-145 and miR-133a transfectants compared with the controls, suggesting that both miRNAs function as tumor suppressors. The aims of our expression studies were identification of these miRNAs target genes.

(Submitter supplied) The imbalances scored by arrayCGH mapped to different chromosomes with losses being more common than gains. Frequent losses of large chromosomal segments were scored from 3p and 8p whereas same-sized gains were frequent from 3q and 8q. This is the first study of vulvar tumors using arrayCGH, and some frequent imbalances could be defined precisely.

(Submitter supplied) The genome of 14 vulvar SCC was analyzed by aCGH and microarray to identify common imbalances present in the tumors as well as which genes were deregulated. Overall there was a good concordance between the imbalances scored by aCGH and the level of gene expression found by microarray, i.e., the genes located in gained regions were overexpressed while those located in lost regions were found down-regulated.

(Submitter supplied) Non-small-cell lung cancer (NSCLC), which is comprised mainly of adenocarcinoma and squamous cell carcinoma (SCC), is the cause of 80% of all lung cancer deaths in the US. NSCLC is also associated with a high rate of relapse following clinical treatment and therefore requires robust prognostic markers to better manage therapy options. The aim of this study was to identify miRNA expression profiles in squamous cell carcinoma (SSC) of the lung that would better predict prognosis.

(Submitter supplied) In order to identify putative targets in squamous cell carcinoma (SCC), a survey of parallel chromosomal alterations and gene expression studies in 10 SCC cell lines were performed using array-CGH and microarray techniques. The most frequent changes were gains of 11q13.1-13.3 and losses of 18q12.1-23 in SCC. Furthermore, the expression levels of the sets of genes at both these loci in SCC were measured using microarray analysis. more...

(Submitter supplied) Our aim is to identify frequent genomic aberrations both in ESCC and esophageal dysplasia, and to discover important copy number-driving genes and microRNAs in ESCC. We carried out array-based comparative genomic hybridization (array CGH) on 59 ESCC resection samples and 16 dysplasia biopsy samples. Expression of genes at 11q13.3 was analyzed by real-time PCR and immunohistochemistry (IHC). Integrated analysis was performed to identify genes or microRNAs with copy number-expression correlations.

(Submitter supplied) Background: Mortality rates of pancreatic cancer remain high, which is mainly due to advanced disease and metastasis. We hypothesized that DNA copy number alteration are enriched in metastatic cells compared to autologous primary tumors, which may inform on cancer-related pathways possibly serving as potential targets for specific therapies. We investigated 18 pancreatic ductal adenocarcinomas, including 39 lymph node and 5 distant metastases after surgical resection. more...

(Submitter supplied) Clinically evident oral lesions, oral epithelial dysplasia, precede development of oral squamous cell carcinomas (SCC) and are considered to transform to cancer by acquisition of genetic or epigenetic alterations. Here, we show that, +3q24-qter, -8pter-p23.1, +8q12-q24.2 and +20 are early events identifying two pathways to oral cancers that differ in clinical behavior. One or more of these copy number aberrations is present in the major subgroup (3q8pq20 subtype, 75-80% of lesions) that develops with chromosomal instability and risk for metastasis, while they are absent from the smaller and chromosomally stable non-3q8pq20 subgroup (20-25% of lesions) associated with low risk for metastasis. more...
