Microsatellite instability is infrequent in neuroblastoma.
Neuroblastoma (NB) is a childhood cancer of the autonomic nervous system. The molecular pathology of NB is not yet well understood. Both amplification of the proto-oncogene N-myc and loss of heterozygosity of several chromosomal loci occur in NB, representing genetic instability. In this study, we examined another type of genetic instability, microsatellite instability. Five chromosomal loci kn...
متن کاملMicrosatellite instability is infrequent in medullary breast cancer.
Microsatellite instability (MSI), characterized by contraction or expansion in microsatellite length or short tandem repeats compared with germline lengths, is found in 85% to 90% of colon cancer arising in hereditary nonpolyposis colorectal cancer families. These cancers commonly have characteristic histologic appearances, including medullary features with intense lymphoid infiltrates. In panc...
متن کاملInfrequent microsatellite instability in papillary carcinomas of the thyroid.
The aim of the present study was to confirm the frequency of microsatellite instability in thyroid cancers. We investigated 26 patients suffering from thyroid cancer (25 papillary carcinomas, 1 follicular carcinoma) using 8 microsatellite markers. Microsatellite instability (MSI) was found in two (7.7%) papillary carcinomas. Our data indicate that MSI is a relatively rare event and may seldom c...
متن کاملHypermutation and microsatellite instability in gastrointestinal cancers
Recent progress in cancer genome analysis using next-generation sequencing has revealed a high mutation burden in some tumors. The particularly high rate of somatic mutation in these tumors correlates with the generation of neo-antigens capable of eliciting an immune response. Identification of hypermutated tumors is therefore clinically valuable for selecting patients suitable for immunotherap...
متن کاملMicrosatellite instability in ulcerative colitis-associated colorectal dysplasias and cancers.
Microsatellites are short nucleotide repeat sequences present throughout the human genome. Alterations of microsatellites, comprising extra or missing copies of these sequences, have been termed microsatellite instability. This abnormality occurs in sporadic and hereditary adenocarcinomas of the proximal colon, as well as in many other tumor types. We determined whether microsatellite instabili...
