Current Status and Challenges of Imaging‐Based Diagnosis of Lymph Node Metastasis in Colon Cancer: The Lymph Node Committee of the Japanese Society for Cancer of the Colon and Rectum

Annals of Gastroenterological Surgery, EarlyView.
This review of the status and challenges of diagnosis of lymph node metastasis in colon cancer suggests that it is currently difficult to establish strict criteria for lymph node metastasis, indicating only moderate diagnostic performance. ABSTRACT Background Accurate pre‐treatment evaluation of lymph node metastasis (LNM) in colon cancer is important ...

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.

LINE-1 hypomethylation in cancer is highly variable and inversely correlated with microsatellite instability. [PDF]

PLoS ONE, 2007
Alterations in DNA methylation in cancer include global hypomethylation and gene-specific hypermethylation. It is not clear whether these two epigenetic errors are mechanistically linked or occur independently.

Testing tumors for microsatellite instability [PDF]

European Journal of Human Genetics, 1999
The methods for determining microsatellite instability in tumors are highly heterogeneous. Recently a 5-marker panel of microsatellites was suggested for this purpose. In this review attention is drawn to the fact that microsatellite instability can be assessed by analyzing tumor DNA with a single marker, BAT-26, and that normal tissue DNA from the ...

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.

Tumor-draining lymph nodes shape the tumor microenvironment through enrichment of tumor-reactive effector-exhausted CD8+ T cells

Signal Transduction and Targeted Therapy
Tumor-draining lymph nodes are central to anti-tumor immunity and influence the response to immunotherapy. Colorectal cancers with microsatellite instability and microsatellite stability differ substantially in tumor biology, prognosis and sensitivity to

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,
