Cytogenetic analysis of choroidal melanoma

Archivos de la Sociedad Española de Oftalmología (English Edition), 2014
To investigate the presence of known cytogenetic alterations of choroidal melanoma in a series of patients diagnosed and treated in our Ocular Oncology Service. A review of the present literature on this topic is also presented.Microsatellite analysis (MSA) studies on loss of heterozygosity (LOH) of chromosome 3, as well as multiplex ligation prove ...

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 in congenital hypothyroidism

Journal of Endocrinological Investigation, 1990
In order to evaluate the possible role of genetic factors in the pathogenesis of congenital hypothyroidism (CH), we investigated the occurrence of chromosome aberrations in a consecutive series of 47 patients with CH and 208 matched healthy controls. No abnormal karyotype was found in CH patients.

Cytogenetic analysis of malignant mesothelioma

Cancer Genetics and Cytogenetics, 1990
Cytogenetic analyses of 40 confirmed malignant mesotheliomas (MMs) are reported. Pleural effusion cells were studied in 90% of the cases by direct method or after culture or both. Biopsy and ascites fluid were also analyzed in some patients. A normal karyotype was found in nine cases, and complex karyotypic abnormalities were observed in 30 cases.

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.

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 ...

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.

Interphase cytogenetic analysis of gliomas

Clinical Neurology and Neurosurgery, 1992
Interphase cytogenetics is the application of nonradioactive in situ hybridization with chromosome-specific DNA probes to interphase nuclei. The possibilities and limitations of this new technique for the study of chromosomal aberrations in gliomas are discussed.
