Lynch syndrome 4

A form of Lynch syndrome, an autosomal dominant disease associated with marked increase in cancer susceptibility. It is characterized by a familial predisposition to early-onset colorectal carcinoma (CRC) and extra-colonic tumors of the gastrointestinal, urological and female reproductive tracts. Lynch syndrome is reported to be the most common form of inherited colorectal cancer in the Western world. Clinically, it is often divided into two subgroups. Type I is characterized by hereditary predisposition to colorectal cancer, a young age of onset, and carcinoma observed in the proximal colon. Type II is characterized by increased risk for cancers in certain tissues such as the uterus, ovary, breast, stomach, small intestine, skin, and larynx in addition to the colon. Diagnosis of classical Lynch syndrome is based on the Amsterdam criteria: 3 or more relatives affected by colorectal cancer, one a first degree relative of the other two; 2 or more generation affected; 1 or more colorectal cancers presenting before 50 years of age; exclusion of hereditary polyposis syndromes. The term 'suspected Lynch syndrome' or 'incomplete Lynch syndrome' can be used to describe families who do not or only partially fulfill the Amsterdam criteria, but in whom a genetic basis for colon cancer is strongly suspected.

Clinical and molecular characteristics of constitutional mismatch repair deficiency syndrome: a case series of five children and appraisal of diagnostic guidelines.

Diagnostic pathology2026 Jan 22

DNA mismatch repair (MMR) is critical for maintaining genome integrity through correction of single-base mismatches and insertion-deletion loops arising from DNA replication. Heterozygous germline alteration of MMR genes (MSH2, MSH6, MLH1, PMS2) cause autosomal dominant Lynch syndrome (LS), most commonly manifesting as colonic or endometrial cancers, although brain, ovarian, and other organ systems may be involved. Neoplasia in LS usually arises after the age of 30 years. Constitutional mismatch repair deficiency (CMMRD) is inherited in an autosomal recessive manner due to biallelic germline alteration in one of the four MMR genes. Individuals with CMMRD typically develop cancer in the first decade of life, although some may present during the second decade. We present a series of five children who developed cancer prior to the age of 20 years (range: 2-12 years) with malignancies including colonic adenocarcinoma (N = 1), T-lymphoblastic lymphoma (N = 3), and high-grade glioma (N = 4). Two patients with MSH6 alterations developed a constellation of three primary tumors: high-grade glioma, T-lymphoblastic lymphoma, and colonic neoplasia including colonic adenocarcinoma in one patient and a tubular adenoma in the other.

A missed opportunity for preventing CMMRD: is it time to include Lynch syndrome genes in prenatal genetic testing?

BMJ case reports2025 Nov 12

This manuscript highlights the importance of incorporating Lynch syndrome-related genes into prenatal genetic testing to facilitate early detection of constitutional mismatch repair deficiency syndrome (CMMRD). CMMRD, linked to biallelic pathogenic variants in mismatch repair genes, is an aggressive hereditary cancer syndrome. A couple conceived through in vitro fertilisation (IVF), unaware they were carriers of Lynch syndrome. Their child, initially healthy, was diagnosed with acute bilineal leukaemia and later found to have CMMRD. His diagnosis highlighted gaps in prenatal testing. Advances in next-generation sequencing enable broader genetic screening, offering parents crucial risk assessment tools, especially those undergoing IVF, to make informed reproductive choices.

Cancer Predisposition Syndromes With Involvement of the Head and Neck Regions in Children: An Imaging Guide.

Journal of neuroimaging : official journal of the American Society of Neuroimaging2025

Cancer predisposition syndromes (CPSs) are a group of inherited disorders that significantly increase the risk of developing various cancers, ranging from infancy through adulthood. CPSs account for about 10% of the pediatric cancers, and they represent a major cause of morbidity and mortality in affected children. The inheritance pattern and the variable penetrance influence the age of onset and the clinical course, resulting in substantial variation in presentation, even within a single family. Early recognition of CPSs is crucial, as timely diagnosis allows for health surveillance, preventive interventions, and genetic counselling for patients and their families. Guidelines and surveillance programs have been developed to identify at-risk patients and coordinate long-term care. This review focuses on the most common CPSs associated with pediatric cancers, with particular emphasis on the involvement of the head and neck region. For each syndrome, we provide a background summary including its genetics and clinical manifestations, followed by a detailed description of characteristic head and neck imaging findings. Illustrative case examples are then presented to demonstrate the spectrum of clinical and imaging features. It highlights imaging features to assist providers reading these studies in the early identification of all possible pathological manifestations in these syndromes. Key CPSs covered include retinoblastoma, Li-Fraumeni syndrome, neurofibromatosis type 1, DICER1 syndrome, rhabdoid tumor predisposition syndrome, Gorlin-Goltz syndrome, hereditary paraganglioma-pheochromocytoma syndrome, constitutional mismatch repair deficiency syndrome, and neuroblastoma predisposition syndrome.

Mismatch Repair Cancer Syndrome presenting as synchronous high-grade glioma and diffuse large B cell lymphoma in a pediatric patient.

Cancer genetics2025 Sep

Development of multiple distinct, synchronous cancer types in a pediatric patient is very rare and should raise suspicion for an underlying genetic predisposition to cancer. We present a previously healthy seven-year-old male who was diagnosed with diffuse large B cell lymphoma after a ruptured appendicitis. During the same hospitalization, he was diagnosed with a high-grade glioma. He underwent subsequent genetic testing, which showed compound heterozygosity for PMS2. He was ultimately diagnosed with Mismatch Repair Cancer Syndrome-4, a subtype of Constitutional Mismatch Repair Deficiency syndrome. His newly discovered cancer predisposition syndrome led to multiple additional family members receiving the same diagnosis, which was especially important in a sibling with leukemia who received hematopoietic stem cell transplantation from an unaffected sibling donor. While rare, cancer predisposition syndromes should be suspected in pediatric patients presenting with two or more synchronous, distinct cancer types.

Utility of Whole-Body Magnetic Resonance Imaging Surveillance in Children and Adults With Cancer Predisposition Syndromes: A Retrospective Study.

JCO precision oncology2025 Mar

Surveillance improves patient outcomes by diagnosing cancer at an early and curable stage for individuals with cancer predisposition syndromes (CPS). Whole-body magnetic resonance imaging (WB-MRI) provides head-to-thigh imaging in one sitting without radiation exposure and is recommended for individuals with increased risk of multisite tumors or cancers. In this study, we evaluated the diagnostic performance of WB-MRI as a screening tool for Li-Fraumeni syndrome (LFS), constitutional mismatch repair deficiency syndrome, hereditary paraganglioma-pheochromocytoma syndrome (HPGL-PCC), and other CPS. A retrospective review of patients with CPS seen at the Cancer Genetics Service, National Cancer Center Singapore was conducted. Patients who underwent WB-MRI screening from 2014 to 2024 were identified to determine the sensitivity and specificity of WB-MRI in early cancer detection. Of the 103 patients with CPS recommended for WB-MRI surveillance, 59 underwent the procedure (57% uptake rate). Among them, 34 (57%) were female and the median age was 32 years (range, 1-74 years). The CPS distributions included 22 (37%) with LFS, 14 (24%) with neurofibromatosis type 1, eight (14%) with Von Hippel Lindau syndrome, and eight (14%) with HPGL-PCC. WB-MRI screening led to a diagnosis of cancer in seven (12%) patients (renal cell carcinoma, prostate adenocarcinoma, osteosarcoma, neuroendocrine tumor); of these, four (57%) received curative treatment. Twelve (20%) patients required additional investigations, with eight (14%) having benign findings. The sensitivity and specificity of WB-MRI in our cohort were 64% and 92%, respectively, with a false-positive rate (FPR) of 8% and a false-negative rate of 36%. WB-MRI is an effective screening tool in patients with specific CPS, demonstrating a high specificity and low FPR.
