A Case of FAP Who Underwent Mucosectomy for Intramucosal Cancer that Repeatedly Developed in the Residual Rectal Mucosa After Stapled Ileal-Pouch Anal Anastomosis

Gan to kagaku ryoho. Cancer & chemotherapy

When we perform stapled ileal pouch anal anastomosis(IPAA)for familial adenomatous polyposis(FAP), some rectal mucosa persists. There is no consensus on surgical treatment when cancer develops at the residual mucosa. We report the case of a 43-year-old woman who repeatedly underwent endoscopic resection for intramucosal cancer that developed in the residual rectal mucosa 6 years after stapled IPAA, which she received at age 33. She was referred t...

This meta-analysis was designed to identify differences in adverse events and functional outcomes between these two groups. METHODS : Studies published between 1986 and 2003 that compared outcomes between patients with familial adenomatous polyposis and ulcerative colitis were includ...

A de novo Desmoid Tumor of the Surgical Site Following Foramen Magnum Meningioma Resection in a Patient with Gardner’s Syndrome: A Case Report and Review of the Literature

Journal of neuro-oncology

BACKGROUND : Gardner’s Syndrome is a familial adenomatous polyposis (FAP) syndrome that presents with colorectal polyps, craniofacial osteomas, lipomas, epidermoid cysts, and ampullary cancers. These patients are at significant risk for developing desmoid tumors, which are locally infiltrating fibromatous lesions. These are most commonly found in the abdominal cavity, but may be extra-abdominal. Although FAP-associated desmoid tumors often occur...

A de novo Germline APC mutation (3927del5) in a Patient with Familial Adenomatous Polyposis: Case Report and Literature Review

Clinical Medicine Insights: Oncology

INTRODUCTION : Characterized by the development of hundreds to thousands of colonic adenomas, classic familial adenomatous polyposis (FAP) is one of the most common hereditary syndromes associated with an increased risk of colorectal cancer. Several studies have attempted to correlate specific APC mutations with clinical phenotype.6 However, there is considerable variability in the expression of specific phenotypes within families and among indiv...

A Distinct Mutation on the Alternative Splice Site of APC Exon 9 Results in Attenuated Familial Adenomatous Polyposis Phenotype

Familial cancer

A subset of APC mutation carriers shows a milder familial adenomatous polyposis phenotype (attenuated FAP) developing smaller number of polyps and colorectal cancer at an older age. It seems that a different mechanism to carcinogenesis is initiated according to the initial site of the germline mutation. The APC gene of a female patient with AFAP phenotypic features was analysed. A novel mutation located on the alternatively splice site of exon 9...

A Large-scale Meta-analysis to Refine Colorectal Cancer Risk Estimates Associated with MutYH Variants

British Journal of Cancer

BACKGROUND: defective DNA repair has a causal role in hereditary colorectal cancer (CRC). Defects in the base excision repair gene MUTYH are responsible for MUTYH-associated polyposis and CRC predisposition as an autosomal recessive trait. Numerous reports have suggested MUTYH mono-allelic variants to be low penetrance risk alleles. We report a large collaborative meta-analysis to assess and refine CRC risk estimates associated with bi-allelic a...

A Proposed Staging System and Stage-Specific Interventions for Familial Adenomatous Polyposis

Gastrointestinal endoscopy

BACKGROUND : It is not possible to accurately count adenomas in many patients with familial adenomatous polyposis (FAP). Nevertheless, polyp counts are critical in evaluating each patient’s response to interventions. However, the U.S. Food and Drug Administration no longer recognizes the decrease in polyp burden as a sufficient chemoprevention trial treatment endpoint requiring a measure of “clinical-benefit.” To develop endpoints for future indu...

ACG Clinical Guideline: Genetic Testing and Management of Hereditary Gastrointestinal Cancer Syndromes

The American Journal of Gastroenterology

This guideline presents recommendations for the management of patients with hereditary gastrointestinal cancer syndromes. The initial assessment is the collection of a family history of cancers and premalignant gastrointestinal conditions and should provide enough information to develop a preliminary determination of the risk of a familial predisposition to cancer.

ACMG Technical Standards and Guidelines for Genetic testing for Inherited Colorectal Cancer (Lynch Syndrome, Familial Adenomatous Polyposis, and MYH-Associated Polyposis)

Genetics in Medicine

Lynch syndrome, familial adenomatous polyposis, and Mut Y homolog (MYH)-associated polyposis are three major known types of inherited colorectal cancer, which accounts for up to 5% of all colon cancer cases. Lynch syndrome is most frequently caused by mutations in the mismatch repair genes MLH1, MSH2, MSH6, and PMS2 and is inherited in an autosomal dominant manner. Familial adenomatous polyposis is manifested as colonic polyposis caused by mutati...

A Germline Homozygous Loss-of-Function Mutation in the Base Excision Repair Gene NTHL1 Causes Adenomatous Polyposis and Colorectal Cancer

European Journal of Human Genetics

Abstract Introduction: Patients diagnosed with adenomatous polyposis, i.e., the constitutive development of multiple colorectal adenomatous polyps, are at an increased risk to develop colorectal cancer (CRC). Currently, two adenomatous polyposis-associated syndromes are known: familial adenomatous polyposis (FAP) and MUTYH-associated polyposis (MAP). Whereas monoallelic APC germline mutations underlie FAP, MAP...

A Serendipitous Diagnosis of Familial Adenomatous Polyposis. What Next?

Fluids and Barriers of the CNS

Poster Presentation Background: A seven-year-old boy with shunted hydrocephalus and spina bifida attended eye screening following strabismus surgery. A serendipitous finding of congenital hypertrophy of the retinal-pigmented epithelium (CHRPE) on fundoscopy, led to a diagnosis of probable familial adenomatous polyposis (FAP). Neither parent had any evidence of CHRPE when screened, consistent with a new mutation in the patient. Genetic assessme...

APC: The Key to Colon Cancer (The APC Protein and Its Role in Controlling the Cell Cycle)

Milwaukee School of Engineering Center for BioMolecular Modeling

Poster Presentation Abstract: Colorectal cancer affects 1 in 18 Americans, and is linked to mutations in the Adenomatous Polyposis Coli (APC) gene. The rapid division of colonocytes is regulated by the Wingless Type (Wnt) signaling pathway, mediated by β-catenin. In the nucleus, β- catenin binds to Transcription Cell Factor (TCF) and initiates transcription of cell cycle proteins. Alternatively, β-catenin binds to the 20-amino acid repeat r...

Desmoid Tumors: Are They Benign or Malignant?

The distinction between benign and malignant tumors is classically based on the metastatic potential of a tumor type. While desmoid tumors do not metastasize and as such are classified as benign lesions, their clinical behavior, cellular biology, and molecular etiology all share more characteristics with malignancies than benign processes. Research into these aspects of desmoid tumor biology has the potential not only to develop better treatments...
