Allelic imbalance and microsatellite instability in prostatic adenocarcinoma.
Although prostate cancer is one of the most common malignancies of males in Western countries, relatively little is known about the molecular mechanisms involved in tumor initiation and progression. Allelic loss studies have suggested the involvement of multiple tumor suppressor genes (TSGs), but few detailed studies of all chromosomes have been performed. In an effort to localize and identify ...
متن کاملMicrosatellite Instability in Korean Patients with Gastric Adenocarcinoma
OBJECTIVES Microsatellites are short repeated oligonucleotide sequences found throughout the human genome. High mutation rates in microsatellite sequences have been found in tumors from patients with hereditary non-polyposis colorectal carcinoma and some sporadic carcinomas. However, little information is available regarding RER-positive phenotype in gastric carcinomas, particularly in terms of...
متن کاملShould the grading of colorectal adenocarcinoma include microsatellite instability status?
Adenocarcinomas of the colon and rectum are graded using a 2-tiered system into histologic low-grade and high-grade tumors based on the proportion of gland formation. The current grading system does not apply to subtypes of carcinomas associated with a high frequency of microsatellite instability (MSI), such as mucinous and medullary carcinomas. We investigated the combined effect of histologic...
متن کاملMedullary colonic carcinoma with microsatellite instability has lower survival compared with conventional colonic adenocarcinoma with microsatellite instability
Introduction Colorectal medullary carcinoma (MC) is a rare subtype of poorly differentiated adenocarcinoma (PDA) with unclear prognostic significance. Microsatellite instable (MSI) colorectal carcinomas have demonstrated better prognosis in clinical stage II. Aim To analyze the survival and clinicopathological characteristics of MCs versus PDAs with MSI in clinical stage III. Material and m...
متن کاملImproved Detection of Microsatellite Instability in Early Colorectal Lesions
Microsatellite instability (MSI) occurs in over 90% of Lynch syndrome cancers and is considered a hallmark of the disease. MSI is an early event in colon tumor development, but screening polyps for MSI remains controversial because of reduced sensitivity compared to more advanced neoplasms. To increase sensitivity, we investigated the use of a novel type of marker consisting of long mononucleot...
