Background: Approximately 1 in 20 cases of colorectal cancer are caused by monogenic syndromes. Published guidelines recommend that patients with 10 or more adenomas be referred for genetic testing, based on evidence that colorectal cancer risk is associated with adenoma multiplicity.
Objective: The aim of this study was to determine adherence to guidelines on referral for genetic screening in patients with 10 or more adenomas.
Design: A cross-sectional study was performed of prospectively collected data from the UK Bowel Cancer Screening Programme between May 2007 and June 2018. Only histologically confirmed adenomas were included. Clinicopathological data were recorded from patient records, and referrals to clinical genetics services were ascertained.
Setting: Data were obtained from 3 centers in London, United Kingdom.
Patients: A total of 17,450 subjects underwent colonoscopy following an abnormal fecal occult blood test.
Main Outcome Measures: We quantified patients with 10 or more adenomas and the proportion referred for genetic screening.
Results: The adenoma detection rate was 50.6% among 17,450 patients who underwent colonoscopy (8831 had 1 or more adenomas). Three hundred forty-seven patients (2.0%) had 10 or more adenomas. Patients with 10 or more adenomas were more likely to be male than those with fewer than 10 adenomas (76.9% vs 53.4%; p < 0.0001). A family history was collected in 37.8% of the multiple adenoma population. Of 347 patients with 10 or more adenomas, 28 (8.1%) were referred for genetic assessment.
Limitations: All 3 screening centers were in a single city. No genetic outcome data were available to permit analysis of actual rates of inherited cancer syndromes in this population.
Conclusions: In this study, almost 1 in 50 patients had 10 or more adenomas. Despite guidelines advising genetic testing in this group, referral rates are low. A referral pathway and management strategies should be established to address this patient population. See Video Abstract at http://links.lww.com/DCR/B630.
Tasas Bajas De Derivacin Para La Evaluacin Gentica De Pacientes Con Adenomas Mltiples En Los Programas De Deteccin Del Cncer De Intestino Del Reino Unido: ANTECEDENTES:Aproximadamente uno de cada veinte casos de cáncer colorrectal son causados por síndromes monogénicos. Las pautas publicadas recomiendan que los pacientes con diez o más adenomas sean derivados para pruebas genéticas, basándose en la evidencia de que el riesgo de cáncer colorrectal está asociado con la multiplicidad de adenomas.OBJETIVO:El objetivo de este estudio fue determinar la adherencia a las guías de derivación para cribado genético en pacientes con diez o más adenomas.DISEÑO:Se realizó un estudio transversal de datos recolectados prospectivamente del Programa de Detección de Cáncer de Intestino del Reino Unido entre mayo de 2007 y junio de 2018. Solo se incluyeron los adenomas confirmados histológicamente. Los datos clínico-patológicos se registraron a partir de los registros de los pacientes y se determinaron las derivaciones a los servicios de genética clínica.AJUSTE ENTORNO CLINICO:Los datos se obtuvieron de tres centros en Londres, Reino Unido.PACIENTES:Un total de 17.450 17450 sujetos pacientes se sometieron a una colonoscopia después de una prueba de sangre oculta en heces anormal positiva.PRINCIPALES MEDIDAS DE RESULTADO VOLARACION:cuantificamos los pacientes con diez o más adenomas y la proporción remitida para cribado genético.RESULTADOS:La tasa de detección de adenomas fue del 50,6% entre 17.450 17450 pacientes que se sometieron a colonoscopia (8.831 8831 tenían uno o más adenomas). 347 pacientes (2,0%) tenían 10 o más adenomas. Los pacientes con 10 o más adenomas tenían más probabilidades de ser hombres que aquellos con menos de 10 adenomas (76,9% frente versus a 53,4%; p <0,0001). Se recogieron antecedentes familiares en el 37,8% de la población de adenomas múltiples. De 347 pacientes con 10 o más adenomas, 28 (8,1%) fueron remitidos para evaluación genética.LIMITACIONES:Los tres centros de detección se encontraban en una sola ciudad. No se disponía de datos de resultados genéticos que permitieran el análisis de las tasas reales de síndromes de cáncer hereditario en esta población.CONCLUSIONES:En este estudio, casi uno de cada cincuenta pacientes tenía diez o más adenomas. A pesar de las pautas que recomiendan las pruebas genéticas en este grupo, las tasas de derivación son bajas. Se debe establecer una vía de derivación y estrategias de manejo para abordar esta población de pacientes. Consulte Video Resumen en http://links.lww.com/DCR/B630.

Introduction: Colorectal cancer (CRC) is the second most common cause of cancer-related deaths globally. The gut microbiota, along with adenomatous polyps (AP), has emerged as a plausible contributor to CRC progression. This study aimed to scrutinize the impact of the FadA antigen derived from Fusobacterium nucleatum on the expression levels of the ANXA2 ceRNA network and assess its relevance to CRC advancement.

Multiple endocrine neoplasia type 1 (MEN1) syndrome is an autosomal dominant disorder caused by a germline pathogenic variant in the MEN1 tumor suppressor gene. Patients with MEN1 have a high risk for primary hyperparathyroidism (PHPT) with a penetrance of nearly 100%, pituitary adenomas (PitAd) in 40% of patients, and neuroendocrine neoplasms (NEN) of the pancreas (40% of patients), duodenum, lung, and thymus. Increased MEN1-related mortality is mainly related to duodenal-pancreatic and thymic NEN.

Aim: The aim of this work was to quantify post-colonoscopy colorectal cancer (PCCRC) rates in National Health Service (NHS) Scotland using World Endoscopy Association guidelines, compare incidence between health boards and referral streams and explore comparisons in results with published data from other healthcare systems.
Method: This is a population-based cohort study using NHS Scotland data between 2012 and 2018. All people undergoing colonoscopy between 2012 and 2018 and subsequently diagnosed as having bowel cancer up to 3 years after their investigation were included.

Fever of unknown origin (FUO) can be a common manifestation of multiple disease processes like infections, hematological & solid organ malignancies, autoimmune disorders, and autoinflammatory diseases. Endocrine causes of FUO are rare but should be considered in differential diagnosis. We present a case of a 35-year-old female with prolonged on-and-off fever and intermittent vomiting for nine months, where extensive workups for chronic infections, malignancy, and autoimmune conditions initially yielded no definitive diagnosis.
