Znaczenie mechanizmu naprawy DNA błędnie sparowanych zasad azotowych (MMR) w raku piersi

Menopause Review, 2010
Background: Microsatellite instability (MSI) is due to defective DNA mismatch repair. Defects in DNA mismatch-repair (MMR) genes lead to replication errors revealed as instability in microsatellite markers.

Characterizing Microsatellite Instability and Chromosome Instability in Interval Colorectal Cancers

Neoplasia: An International Journal for Oncology Research, 2018
There are a substantial portion of colorectal cancers (CRCs), termed interval CRCs (I-CRCs), that are diagnosed shortly after a negative colonoscopy (i.e., no detectable polyps or CRC) and before recommended follow-up screening.

Differential Prognostic Impact of Prior Cholecystectomy Between Proximal and Distal Colorectal Cancer: A 12‐Year Retrospective Cohort Study of 3487 Consecutive Patients

Annals of Gastroenterological Surgery, EarlyView.
In this retrospective cohort of 3487 patients with CRC, history of CCY was associated with significantly worse prognosis in patients with proximal CRC but not in those with distal CRC. This differential prognostic impact showed a statistically significant interaction between tumor location and history of CCY and remained robust after PSM.

Analysis of the molecular nature associated with microsatellite status in colon cancer identifies clinical implications for immunotherapy

Journal for ImmunoTherapy of Cancer, 2020
Background Microsatellite instability in colon cancer implies favorable therapeutic outcomes after checkpoint blockade immunotherapy. However, the molecular nature of microsatellite instability is not well elucidated.Methods We examined the immune ...

Improving genetic diagnosis of hereditary tumor syndromes: From expanded gene panels to functional genomics

International Journal of Cancer, EarlyView.
Abstract Genetic tumor risk syndromes (genturis) contribute substantially to the overall cancer burden and provide opportunities for early detection, prevention, and individualized treatment. Yet, many affected individuals remain undiagnosed due to restrictive testing criteria and challenges in variant interpretation.

Living at genetic risk: The patient experience of Lynch syndrome

International Journal of Cancer, EarlyView.
Abstract Lynch syndrome is a germline cancer predisposition syndrome caused by a variant in one of four genes. Lynch syndrome places individuals at significantly higher risk for a range of cancers, especially colorectal and endometrial. Depending on which gene is affected, the risk of ovarian, gastric, small bowel, pancreatic, biliary urothelial, brain,

Molecular–clinical characteristics and treatment outcomes in 163 metastatic colorectal neuroendocrine carcinomas with a comparison to colorectal adenocarcinomas

International Journal of Cancer, EarlyView.
What's New? Colorectal neuroendocrine carcinoma (CR‐NEC) is a rare digestive neuroendocrine neoplasm that frequently exhibits an adenocarcinoma component. Nonetheless, the underlying biology of CR‐NEC remains poorly understood. This study examined molecular and clinical features and palliative chemotherapy outcomes of metastatic CR‐NEC, with comparison

A multilevel perspective on MSH6‐associated Lynch syndrome: Integrating molecular, biological, and clinical insights

International Journal of Cancer, EarlyView.
Abstract Lynch syndrome (LS) is the most common hereditary colorectal cancer syndrome, caused by a germline pathogenic variant in one of the mismatch repair (MMR) genes. Among these, MSH6‐associated LS represents a distinct subtype with unique molecular and clinical characteristics.

Detection of MSI signals from peripheral blood for monitoring response to immune checkpoint blockade therapy in patients with advanced microsatellite‐unstable gastrointestinal cancers: A pilot study

International Journal of Cancer, EarlyView.
What's New? A substantial proportion of patients with microsatellite‐unstable gastrointestinal adenocarcinomas do not benefit from immunotherapy. This study demonstrates that microsatellite instability can be reliably detected in plasma‐derived extracellular vesicle DNA from patients with microsatellite‐unstable gastrointestinal cancers.
