Cytogenetic analysis of a congenital fibrosarcoma

Cancer Genetics and Cytogenetics, 1991
Congenital (infantile) fibrosarcoma is a rare soft tissue sarcoma occurring in children aged less than 5 years. We performed cytogenetic analysis on such a tumor, which had an abnormal karyotype: 48,XY, +11, +20. Three other reports of karyotypes in congenital fibrosarcoma describe similar cytogenetic changes, and a specific pattern of trisomies that ...

Cytogenetic analysis of 5572 patients referred for suspected chromosomal abnormalities in Morocco.

Genetic Testing and Molecular Biomarkers, 2012
OBJECTIVES The aim of this study was (1) to identify the profile of patients being referred for cytogenetic analysis in Morocco, (2) to determine the prevalence and type of chromosomal abnormalities in the different groups, (3) to compare the results ...

Cytogenetic analysis of human blastocysts

Prenatal Diagnosis, 2002
AbstractThe human blastocyst is key to understanding the aetiology of constitutional chromosome abnormalities in our species.ObjectivesTo investigate the range and incidence of chromosome abnormalities in a large series of human blastocysts, using classic cytogenetic techniques.MethodsUsing thymidine, cell division is synchronized in spare five‐to ...

Cytogenetic analysis of dedifferentiated chondrosarcoma

Cancer Genetics and Cytogenetics, 1996
Cytogenetic analysis of a dedifferentiated chondrosarcoma with a fibrosarcomatous component revealed the following chromosomal complement: 47,XX,i(1)(q10), add(6)(q13),+7,+8,t(10;12) (p11.2;q11.2),+14,-15,-17, add(19)(q13,4). Chromosome studies of dedifferentiated chondrosarcoma are sparse.

Classical and Molecular Cytogenetic Analysis

2012
Cytogenetic analysis is performed on cell cultures for several reasons, notably, to perform identity checks by verifying species of origin or the retention of key chromosome rearrangements in cell lines described previously. De novo chromosome analysis is usually performed when characterizing cancer cell lines for the presence of neoplastic ...

Review of Bayesian statistical analysis methods for cytogenetic radiation biodosimetry, with a practical example.

Radiation Protection Dosimetry, 2014
Classical methods of assessing the uncertainty associated with radiation doses estimated using cytogenetic techniques are now extremely well defined. However, several authors have suggested that a Bayesian approach to uncertainty estimation may be more ...

Cytogenetic Analysis of Sinonasal Carcinomas

Otolaryngology–Head and Neck Surgery, 2006
BACKGROUNDSinonasal carcinomas, including nonkeratinizing (NK) squamous cell carcinoma (SCC) and sinonasal undifferentiated carcinoma (SNUC), are uncommon malignant neoplasms arising from the Schneiderian respiratory epithelium of the nasal cavity and paranasal sinuses.

Cytogenetic Analysis and Reporting

2011
Use of appropriate methods to produce analysable metaphase spreads and high-quality fluorescence in situ hybridization (FISH) and array results is critical to successful cytogenetic analysis of haematological malignancies, but the analysis and reporting of the findings of these tests are equally important as it is the final report that clinicians rely ...

Cytogenetic analysis in human neurinomas

Cancer Genetics and Cytogenetics, 1987
In a recent report, Seizinger et al. [1], using a molecular genetic approach, have shown that acoustic neuroma is associated with loss of genes on chromosome #22, suggesting a mechanism of tumorigenesis similar to that found in embryonal tumors [2-6].

Cytogenetic Analysis of Tumor Clonality

2011
All or almost all neoplasias subjected to systematic cytogenetic scrutiny have been found to harbor acquired chromosomal aberrations. The paradigm stemming from the study of hematopoietic malignancies and sarcomas is that cancers are of monoclonal origin (i.e., they have developed from a single transformed somatic progenitor) because all the neoplastic
