Chromosomal instability (CIN) is classically defined as an increase in the rate at which numerical or structural chromosomal aberrations are acquired in a cancer cell. The number of somatic copy number abnormalities (CNAs) revealed by high resolution genomic array can be considered as a surrogate marker for CIN, but several points, related to sample processing and data analysis, need to be standardized. In this work we analyzed 51 CRC samples and matched normal mucosae by whole genome SNP arrays and compared different bioinformatics tools in order to identify broad (>25% of a chromosomal arm) and focal somatic copy number abnormalities (BCNAs and FCNAs respectively)...

A next-generation FISH probe mapping to the MDM2 locus-specific region has recently been designed. The level of MDM2 gene amplification (high versus low) may allow selection of patients for cancer treatment with MDM2 inhibitors and may predict their responsiveness. We investigated the spectrum of MDM2 gene alterations using the new probes in vivo after visualizing single neoplastic cells in situ from a series of glioblastomas. Signals from next-generation repeat-free FISH interphase probes were identified in tissue microarrays that included 3 spots for each of the 48 cases...

Germline mutations in the BRCA tumor suppressor genes account for a substantial proportion of hereditary breast/ovarian cancer. However, this contribution is lower than expected. This underestimation can partly be explained by the BRCA alterations missed by using Sanger sequencing methods. Thus, large genomic rearrangements (LGRs) in BRCA1 and BRCA2 are responsible for 4-28% of all inherited BRCA mutations. In this study, Multiplex ligation-dependent probe amplification (MLPA) assay was used for detection of large rearrangements of BRCA1 and BRCA2 genes in 36 unrelated high-risk breast/ovarian cancer patients negative for BRCA1/2 point mutations...

This study evaluates prognostic markers as predictors of clonal evolution (CE) and assesses the impact of CE on overall survival (OS) in a population-based cohort of 159 consecutive eligible patients with chronic lymphocytic leukemia (CLL) obtained from the British Columbia Provincial CLL Database. CE was detected by interphase fluorescence in situ hybridization (FISH) in 34/159 patients (21%) with 65% of CE patients acquiring deletion 17p or 11q. CD38 positive status (≥30%) on flow cytometry predicted 2...

Oncology is and will continue to evolve resulting from a better understanding of the biology and intrinsic genetic profile of each cancer. Tumor biomarkers and targeted therapies are the new face of precision medicine, so it is essential for all physicians caring for cancer patients to understand and assist patients in understanding the role and importance of such markers and strategies to target them. This review was initiated in an attempt to identify, characterize, and discuss literature supporting clinically relevant molecular markers and interventions...

Cholangiocarcinoma (CCA) is an aggressive malignancy that originates from the epithelial cells of the biliary duct system. Depending on the anatomical location, CCA can be considered extrahepatic (eCCA) or intrahepatic (iCCA) (1). Two thirds of CCAs involve the extrahepatic biliary system, whereas the rest are confined within the liver parenchyma, beyond the secondary biliary radicals (2). Due to its biological aggressiveness and difficulty in diagnosis, the majority of patients with CCA are unresectable at presentation and the overall 5-year survival is approximately five percent (4)...

Molecular targeted therapy is widely utilized and effective in a number of solid tumors. In pancreatic adenocarcinoma, targeted therapy has been extensively evaluated; however, survival improvement of this aggressive disease using a targeted strategy has been minimal. The purpose of this study is to review therapeutic molecular targets in completed and ongoing later phase (II and III) clinical trials to have a better understanding of the rationale and progress towards targeted molecular therapies for pancreatic cancer...

The incidence of pancreatic cancer, the fourth leading cause of cancer death in United States, is increasing worldwide. Even though the cure rate has doubled in 40 years, it is abysmally poor at 6-7%. As surgical resection remains the only curative treatment and less than 20% of the newly diagnosed cancers are resectable, the major burden of disease management lies in early diagnosis, good prognostication, and proper neo-adjuvant and/or adjuvant therapy. With advancing technologies and their ease of availability, researchers have better tools to understand pancreatic cancer...

The liver is a site of metastasis in 25% of metastatic cancers (Abbruzzese et al., 1995). In Western countries, metastases are the most common type of malignant neoplasms in the liver. The majority of liver metastases arise from carcinomas, but other primary tumor types should also be considered, such as lymphomas, sarcomas, melanomas, and germ cell tumors. Of primary liver malignancies, hepatocellular carcinoma is the most common (Hertz et al., 2000). The differentiation between metastatic carcinoma to the liver and primary hepatocellular carcinoma is sometimes challenging...

Testicular germ cell tumours of young adults are comprised of a heterogeneous group of non-seminomas and a homogeneous group of seminomas. While the majority of seminomas retain a hypo-methylated genome, a small fraction displays a highly methylated genome, resembling hyper-methylated non-seminomas. It is well established from e.g. melanoma, colorectal and thyroid cancer that a methylated phenotype can be correlated to prognosis and can be related to BRAF mutations. In the present study we investigated the global methylation level in 67 seminomas and classified them as hypo-methylated, intermediate, patchy and hyper-methylated, respectively...

Myoepithelial carcinoma of the breast is an extremely rare tumor composed entirely of malignant spindle cells with myoepithelial differentiation. The majority of previously reported cases have mainly described the clinicopathological features of the disease, and few have presented cytogenetic data. We herein present the case of a 48-year-old woman who was admitted with a left-sided breast lump in the inner upper quadrant that was initially diagnosed as a myoepithelioma with potentially malignant disorder. At 12 months after resection, she complained about a newly developed solid mass in the subareolar region of the ipsilateral breast that was diagnosed as an invasive ductal carcinoma...

Lynch syndrome is a hereditary cancer syndrome caused by the autosomal dominant inheritance of loss-of-function mutations in DNA mismatch repair (MMR) genes. Approximately one quarter of clinically suspected cases have no identifiable germline mutation in any MMR gene, a condition known as Lynch-like syndrome (LLS). MCM9 was recently identified as the DNA helicase in the mammalian MMR complex and loss of helicase activity results in microsatellite instability. We hypothesized that pathogenic variants in MCM9 may account for LLS...

MicroRNAs (miRNAs), small noncoding regulatory RNAs, are key regulators of gene expression. The impact of Pri-miR-34b/c rs4938723 variant on development of various cancers is still controversial. In the present study, we examined whether a rs4938723 variant located at the promoter region of Pri-miR-34b/c is associated with childhood ALL. A total of 110 children with acute lymphoblastic leukemia (ALL) and 120 healthy children were recruited to participate in this study. The rs4938723 variant was genotyped by polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) method...

Ascertaining the clinical consequences of BRCA1 and BRCA2 variants of uncertain significance (VUS) is currently indispensable for providing effective genetic counseling and preventive actions for families with hereditary breast and ovarian cancer (HBOC). To this end, we conducted a combination of in silico prediction and cDNA splicing analyses of 13 BRCA1 and 10 BRCA2 VUS identified in our cohort as well as a case-control analysis in a population-based sample of 10 recurrent VUS. We observed consistent results between the in silico predictions and sequencing analyses for all analyzed VUS...

CYP2B6 is a polymorphic detoxification gene which plays a vital role in the degradation of genotoxic compounds. In this study we hypothesized that inadequate detoxification due to CYP2B6 polymorphisms may contribute to AML. To evaluate the potential impact of CYP2B6 polymorphisms on AML development and induction of its specific chromosomal abnormalities we studied C(777)A and A(785)G polymorphisms for the first time in AML. Furthermore, we investigated the co-existence of the above polymorphisms with G(516)T polymorphism to determine the CYP2B6 high-risk haplotypes in AML susceptibility...

Epidermolytic palmoplantar keratoderma (EPPK) is a rare autosomal dominant skin disorder characterized by diffuse hyperkeratosis on the palms and soles. Whole-exome sequencing (WES) has become a powerful tool for the detection of rare causal variants of Mendelian disorders. However, no causal gene for EPPK in the Uygur population has been identified until now, and no treatment exists than can address the underlying pathology.WES analysis was undertaken on two individuals from a large Uygur EPPK pedigree whose disease locus mapped to 17q21...

Approximately 5-10% of chronic myeloid leukemia (CML) patients are found to have structural or numerical additional chromosomal abnormality (ACAs) in addition to the characteristic t(9;22)(q34;q11.2) BCR/ABL1 at the time of diagnosis. The prognostic significance of such additional chromosomal abnormalities has been controversial. Translocation t(11;14)(q13;q32) CCND1-IGH is typically associated with mantle cell lymphoma or a subset of plasma cell myeloma and is exceedingly rare in myeloid neoplasm. Here we report a unique case describing a patient found at diagnosis of chronic phase CML to have both the Philadelphia chromosome as well as t(11;14)-a rare cytogenetic combination...

Sporadic melanoma malignancy is correlated with constitutive secretion of IL-1β in transformed melanocytes suggesting the involvement of inflammasome in melanoma. Common variants in inflammasome genes are known to affect IL-1β expression. To investigate the contribution of inflammasome genetics in melanoma development and progression and to identify a potential prognostic marker, the distribution of selected inflammasome SNPs was analysed in a Brazilian case/control cohort of sporadic malignant melanoma (SMM) and then the expression of inflammasome components was evaluated in melanoma biopsies...
