Clinical Aspects of Microsatellite Instability Testing in Colorectal Cancer

Advanced Biomedical Research, 2018
Microsatellite instability (MSI) is a molecular hallmark for some colorectal cancers (CRCs) in which short tandem repeats are prone to mutations along with DNA sequences.

Exome Sequencing Identifies Variants in MLH1 and ERBB2 as Potential Cancer‐Predisposing Factors in Familial Early‐Onset Colorectal Cancer

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Colorectal cancer (CRC) has raised considerable health concerns worldwide, with increasing incidence rates, specifically among younger populations. Despite remarkable progress in diagnosing and treating various diseases, the genetic basis of CRC remains only partially understood.

Microsatellite Instability in Malignant Melanomas

Acta Dermato-Venereologica, 2001
Microsatellite instability (MSI) is caused by deficient DNA mismatch repair, and results in a "mutator" phenotype. Recent studies have produced contradictory results about the frequency and significance of MSI in malignant melanomas. In this study, we therefore determined the time of onset and relative frequency of MSI during the progression of ...

Data‐Independent Acquisition Mass Spectrometry in Tumor Classification and Cancer Biomarker Research

Mass Spectrometry Reviews, EarlyView.
Abstract Cancer treatment is far from optimal also because current classification systems do not reflect the complex molecular status of the tumor and its phenotype in sufficient detail. To construct molecular tumor classifiers, omics tools provide complex molecular data reflecting many aspects from genotype to phenotype.

Analysis of the Matrix Metalloproteinases Family Profile in Gastric Cancer Suggests Key Matrix Metalloproteinases for Tumor Development and Their Clinical Impact

Molecular Carcinogenesis, EarlyView.
ABSTRACT Gastric cancer (GC) is the fifth most common type worldwide, representing a public health problem. Among the genes related to this tumorigenesis, the family of matrix metalloproteinases (MMPs), essential regulators of the extracellular matrix (ECM), stand out for their involvement in the development and progression of GC.

Microsatellite instability in colorectal cancer

British Journal of Surgery, 2006
Abstract Background Microsatellite instability (MSI) causes hereditary non-polyposis colorectal cancer (HNPCC), and occurs in about 15 per cent of sporadic colorectal cancers. Although the basic mechanisms are not clear, there is increased understanding of the clinicopathological consequences of MSI.

Nano Delivery Strategy Opens Effective Avenues for the Treatment of Colorectal Cancer

Medicine Bulletin, EarlyView.
ABSTRACT Colorectal cancer (CRC) presents significant therapeutic challenges because of chemoresistance, systemic toxicity, and the complexity of the tumor microenvironment (TME). Nanodrug delivery systems (NDDS) have emerged as versatile platforms capable of overcoming these limitations by enhancing tumor accumulation, improving pharmacokinetics, and ...

Liver Transplantation After Combination Therapy Based on Immune Checkpoint Inhibitors: A Multicenter Retrospective Study of Safety and Efficacy

Organ Medicine, EarlyView.
This multicenter retrospective study assessed preoperative immune checkpoint inhibitor (ICI) therapy in 17 hepatocellular carcinoma patients undergoing liver transplantation. All received at least one cycle of ICI‐based combination therapy before transplant and achieved a 76.5% objective response rate.
