Chromosomal instability in microsatellite-unstable and stable colon cancer.
PURPOSE The genomic instability in colon cancer can be divided into at least two major types, microsatellite instability (MSI) or chromosomal instability (CIN). Although initially felt to be mutually exclusive, recent evidence suggests that there may be overlap between the two. The aim of this study was to identify chromosomal alterations at high resolution in sporadic colon cancers with high-l...
متن کاملChromosomal Instability in BRAF Mutant, Microsatellite Stable Colorectal Cancers
The BRAF oncogene is mutated in 15% of sporadic colorectal cancers. Approximately half of these BRAF mutant cancers demonstrate frequent frameshift mutations termed microsatellite instability (MSI), but are diploid and chromosomally stable. BRAF wild type cancers are typically microsatellite stable (MSS) and instead acquire chromosomal instability (CIN). In these cancers, CIN is associated with...
متن کاملPIK3CA mutations predict recurrence in localized microsatellite stable colon cancer
PIK3CA, which encodes the p110α catalytic subunit of PI3Kα, is one of the most frequently altered oncogenes in colon cancer (CC), but its prognostic value is still a matter of debate. Few reports have addressed the association between PIK3CA mutations and survival and their results are controversial. In the present study, we aimed to clarify the prognostic impact of PIK3CA mutations in stage I-...
متن کاملThe pathological phenotype of colon cancer with microsatellite instability.
INTRODUCTION Colorectal cancer is a common malignant disease, caused by different aetiologies and molecular pathways. Heterogeneous results have been published regarding the association of microsatellite instability and clinicopathological features. The aim of this study was to compare clinicopathological features of microsatellite unstable tumours with stable ones. METHODS Data were collecte...
متن کاملMolecular Analysis of Microsatellite Instability in Hereditary Non Polyposis Colon Carcinoma Patients from North-East Iran
Background and Objectives: Hereditary nonpolyposis colorectal cancer (HNPCC) is an autosomal dominant cancer predisposition syndrome caused by germ-line mutations in DNA mismatch repair genes. Tumors arising as a result of these mutations display instability in a sequence area known as microsatellites. Studies have shown that some Bethesda markers (BAT25, BAT26) are more efficient than other...
