Abstract
Since its release in 2022, Chat Generative Pre-Trained Transformer (ChatGPT) became the most rapidly expanding consumer software application in history,1 and its role in medicine is underscored by its potential to enhance patient education and physician-patient communication. Previous studies in gastroenterology and hepatology have focused primarily on the earlier Generative Pre-Trained Transformer 3 (GPT-3) model, with none investigating ChatGPT's ability to generate supportive references for its responses, or its applicability as a physician educational tool.2-6 Our study evaluated the accuracy of the more recent ChatGPT, powered by GPT-4, in addressing frequently asked questions by patients on irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), colonoscopy and colorectal cancer (CRC) screening, questions on CRC screening from a physician perspective, and reference generation and suitability.

Abstract
We demonstrate the technical details of laparoscopic-assisted endoscopic 'clean sweep' for small bowel polyp clearance in Peutz Jeghers Syndrome. A 'clean sweep' reduces the risk for future recurrences but was previously performed with an open technique. A minimally invasive approach is safe, reduces bowel trauma and has good postoperative outcomes.

Abstract
Background and study aims Published studies report a higher adenoma detection rate (ADR) for FIT-DNA as compared with FIT. Data are less replete about the performance of stool-based tests for sessile serrated polyp (SSP) detection. We performed a meta-analysis to evaluate the performance of FIT and FIT-DNA testing for SSP detection rate (SSPDR) in patients undergoing colonoscopy for follow up of positive noninvasive tests. Methods A comprehensive literature search of multiple databases (until September 2022) was performed to identify studies reporting SSPDR in patients with positive FIT or FIT-DNA tests. The outcome was overall colonoscopy detection of any SSPs and advanced serrated polyps (ASP: SSP ≥ 10 mm and/or dysplasia). Results Included were 482,405 patients (52.4% females) with a mean age of 62.3 ± 4.4 years from 23 studies. The pooled SSPDR for all positive stool-based tests was 5.3% and higher for FIT-DNA (15.0%, 95% confidence interval [CI] 8.3-25.7) versus FIT (4.1%, 95% CI 3.0-5.6; P = 0.0002). The overall pooled ASP detection rate was 1.4% (95% CI 0.81-2.3) and higher for FIT-DNA (3.8 %, 95% CI 1.7-8.6) compared with FIT (0.71%, 95% CI 0.36-1.4; P <0.01). SSPDR with FIT-DNA was also significantly higher than FIT when the FIT cutoff was >10 ug/g and in FIT-positive patients in studies conducted in North America ( P <0.05). Conclusions FIT-DNA outperformed FIT in both SSP and ASP detection including FIT with a lower threshold cutoff of >10 ug/g. Further comparative studies are needed to assess the impact of our findings on colorectal cancer reduction.

Abstract
BACKGROUND Prophylactic surgery for familial adenomatous polyposis has evolved over several decades. Restorative proctocolectomy with IPAA provides an alternative to total abdominal colectomy with ileorectal anastomosis. We have previously shown that the rate of proctectomy and rectal cancer after total abdominal colectomy with ileorectal anastomosis in the "pre-pouch era" was 32% and 13%, respectively. OBJECTIVE To determine the rate of proctectomy and rectal cancer among familial adenomatous polyposis patients and relative rectal sparing (fewer than 20 rectal polyps) selected for total abdominal colectomy with ileorectal anastomosis in the modern era. DESIGN Retrospective cohort study. SETTING Single tertiary care institution with a hereditary colorectal cancer registry. PATIENTS Patients with familial adenomatous polyposis who underwent total abdominal colectomy with ileorectal anastomosis between 1993 and 2020. MAIN OUTCOME MEASURES Incidence of proctectomy for any indication and rectal cancer. RESULTS A total of 197 patients with a median age of 24 years (range, 10-67) were included. The median follow-up after total abdominal colectomy with ileorectal anastomosis was 13 years (interquartile range, 6-17). Sixteen patients (8%) underwent proctectomy. Indications included rectal cancer in 6 patients (3%; 2 stage I and 4 stage III), polyps with high-grade dysplasia in 4 (2%), progressive polyp burden in 3 (1.5%), defecatory dysfunction in 2 (1%), and anastomotic leak in 1 (0.5%). Among 30 patients (18%) with 20 or more rectal polyps at the time of total abdominal colectomy with ileorectal anastomosis, 8 patients (26%) underwent proctectomy and 3 patients developed rectal cancer (10%). Among 134 patients (82%) with fewer than 20 polyps, 8 patients (6%) underwent proctectomy and 3 patients developed rectal cancer (2%). Number of rectal polyps at the time of total abdominal colectomy with ileorectal anastomosis was associated with the likelihood of proctectomy (OR 1.1, p < 0.001) but not incident rectal cancer ( p = 0.3). LIMITATION Retrospective data collection. CONCLUSIONS Patients with familial adenomatous polyposis selected for total abdominal colectomy with ileorectal anastomosis by rectal polyp number have low rates of proctectomy and rectal cancer compared to historical controls. With appropriate selection criteria and surveillance, total abdominal colectomy with ileorectal anastomosis remains an important and safe treatment option for patients with familial adenomatous polyposis.

RIESGO DE PROCTECTOMA DESPUS DE ANASTOMOSIS ILEORRECTAL EN POLIPOSIS ADENOMATOSA FAMILIAR EN LA ERA MODERNA ANTECEDENTES:La cirugía profiláctica para la poliposis adenomatosa familiar (PAF) ha evolucionado durante varias décadas. La proctocolectomía restauradora con anastomosis anal con bolsa ileal (IPAA) proporciona una alternativa a la colectomía abdominal total con anastomosis ileorrectal (TAC/IRA). Anteriormente hemos demostrado que la tasa de proctectomía y cáncer de recto después de TAC/IRA en la era "pre-bolsa" era del 32% y el 13%, respectivamente.OBJETIVO:Determinar la tasa de proctectomía y cáncer de recto entre pacientes con PAF y pacientes con preservación rectal relativa (<20 pólipos rectales) seleccionados para TAC/IRA en la era moderna.DISEÑO:Estudio de cohorte retrospectivo.ÁMBITO:Institución única de atención terciaria con un registro de cáncer colorrectal hereditario.PACIENTES:Pacientes con PAF que se sometieron a TAC/IRA entre 1993 y 2020.MEDIDAS DE RESULTADO PRINCIPALES:Incidencia de proctectomía por cualquier indicación y cáncer de recto.RESULTADOS:Se incluyeron 197 pacientes con una mediana de edad de 24 años (rango 10-67). La mediana de seguimiento tras TAC/IRA fue de 13 años (RIC 6-17). 16 pacientes (8%) fueron sometidos a proctectomía. Las indicaciones incluyeron cáncer de recto en 6 (3%) (2 en estadio I y 4 en estadio III); pólipos con displasia de alto grado en 4 (2%); carga progresiva de pólipos en 3 (1,5%), disfunción defecatoria en 2 (1%); y fuga anastomótica en 1 (0,5%). Entre 30 pacientes (18%) con ≥20 pólipos rectales en el momento de TAC/IRA, 8 pacientes (26%) se sometieron a proctectomía y 3 pacientes desarrollaron cáncer de recto (10%). Entre 134 pacientes (82%) con <20 pólipos, 8 pacientes (6%) se sometieron a proctectomía y 3 pacientes desarrollaron cáncer de recto (2%). El número de pólipos rectales en el momento de TAC/IRA se asoció con la probabilidad de proctectomía (OR 1,1, p <0,001), pero no con la incidencia de cáncer de recto (p = 0,3).LIMITACIÓN:Recopilación de datos retrospectivos.CONCLUSIÓN:Los pacientes con PAF seleccionados para TAC/IRA por el número de pólipos rectales tienen tasas bajas de proctectomía y cáncer de recto en comparación con los controles históricos. Con criterios de selección y vigilancia adecuados, TAC/IRA sigue siendo una opción de tratamiento importante y segura para los pacientes con PAF. (Pre-proofed version ).

Abstract
We describe here an individual from a fourth family with germline compound heterozygous MSH3 germline variants and its observed biological consequences. The patient was initially diagnosed with invasive moderately-differentiated adenocarcinoma of the colon at the age of 43. Germline multigene panel testing revealed a pathogenic variant MSH3 c.2436-1 G > A and a variant of (initial) uncertain significance MSH3 c.3265 A > T (p.Lys1089*). Germline genetic testing of family members confirm the variants are in trans with the c.2436-1 G > A variant of paternal and the c.3265 A > T variant of maternal origin. Tumor DNA exhibits low levels of microsatellite instability and elevated microsatellite alterations at selected tetranucleotide repeats (EMAST). Tissue immunohistochemical staining for MSH3 demonstrated variant MSH3 protein is present in the cytoplasm and cell membrane but not in the nucleus of normal and tumor epithelial cells. Furthermore, variant MSH3 is accompanied by loss of nuclear MSH6 and a reduced level of nuclear MSH2 in some tumor cells, suggesting that the variant MSH3 protein may inhibit binding of MSH6 to MSH2.

Abstract
BACKGROUND Colorectal cancer (CRC) is rising in young adults between ages 20 to 49 years. CRC screening is endorsed for average-risk individuals beginning at ages 45 to 49 years. Targeting screening for individuals <45 years may be warranted if risk factors for advanced neoplasia can be identified. AIM To identify factors associated with advanced colorectal neoplasia in adults aged <45 years. METHOD Individuals ages 18 to 44 years who underwent colonoscopy at Cleveland Clinic between 2011 and 2021 with ≥1 advanced neoplasm (AN) were included. Patients with inflammatory bowel disease or inherited CRC syndromes were excluded. Demographics, comorbidities, family history of CRC, and colonoscopy indication were obtained. Patients with a normal colonoscopy constituted the control group. A multivariable logistic regression model was used to investigate the relationship between clinical variables and the presence of advanced colorectal neoplasia. RESULTS In all, 13,006 patients were included, of which 651 (5%) patients had AN: 404 (62%) with tubular adenoma ≥10 mm, 29 (4.5%) tubular adenoma with high-grade dysplasia, 210 (32%) tubulovillous adenomas, 27 (4%) traditional serrated adenomas, 82 (13%) sessile serrated lesions ≥10 mm, 7(2%) sessile serrated lesions with dysplasia, and 29 (4.4%) patients had a CRC. Factors associated with AN were older age (means 38.5 vs. 36.6 y), history of smoking, diabetes, non-White race, higher body mass index (29.9 vs. 28.5 kg/m2), and lower vitamin D (27.6 vs. 32.2 ng/dl), all P<0.001. In the reduced multivariable model, factors associated with AN included tobacco use (OR 2.026 (current vs. never, P<0.0001), age (OR increase by 1.06 per year, P<0.0001), male gender (OR 1.476, P<0.0001), family history of CRC (OR 3.91, P<0.0001), aspirin use (1.31, P=0.035), and diabetes (OR 2.106, P 0.001). CONCLUSION Increasing age, male gender, exposure to tobacco, family history of CRC, diabetes, and aspirin use were independently associated with advanced neoplasia in adults younger than 45. Targeted early screening to young adults with these risk factors may be justified. Large collaborative prospective studies are needed to validate our findings.

Abstract
BACKGROUND Patients with familial adenomatous polyposis who have undergone restorative proctocolectomy can develop adenomas in the pouch. OBJECTIVE To review experience with pouch surveillance and create a classification system for polyposis severity. DESIGN A retrospective review of patients undergoing IPAA and follow-up at 1 institution. SETTING A center for hereditary colorectal cancer within a quaternary referral center. PATIENTS All patients undergoing IPAA and followed endoscopically after surgery by the center. INTERVENTIONS Yearly pouchoscopy and treatment of polyps as required. MAIN OUTCOME MEASURES Primary outcome measure was incidence and severity of pouch neoplasia and its changes with time. METHODS A retrospective study of patients who had a restorative proctocolectomy for familial adenomatous polyposis at Cleveland Clinic. Severity of polyposis was classified on the basis of size, number, and histology. RESULTS One hundred sixty-five patients were analyzed. The median age at IPAA was 31 years and 52% were male. The median follow-up was 10.1 years; the median number of pouchoscopies per patient was 4. The median interval between pouchoscopies was 21.9 months. Overall, the incidence of pouch adenomas was found in 47 patients (28.5%). The median time from pouch to first pouch adenoma diagnosis was 10.3 years. The estimated cumulative incidence rates of pouch adenoma at 5, 10, 15, 20, and 30 years after IPAA were 5.9%, 21.7%, 40%, 54.8%, and 69.9%, respectively. At the first diagnosis of pouch adenoma, 25 patients had stage 1, 10 had stage 2, 8 had stage 3, and 4 had stage 4. Twenty of 47 patients progressed to a higher stage. No patient developed cancer. LIMITATIONS Genotype was not available for all patients. CONCLUSIONS There is an increasing incidence of pouch neoplasia after restorative proctocolectomy, reaching a plateau at 25 years. The polyposis is usually mild but sometimes increases in severity.

Incidence and risk factors for recurrence of ampullary adenomas after endoscopic papillectomy: Comparative analysis of familial adenomatous polyposis and sporadic ampullary adenomas in an international multicenter cohort. Dig Endosc 2023.

Abstract
OBJECTIVES Endoscopic papillectomy (EP) is a minimally invasive therapy for the management of ampullary adenomas (AA). We conducted this multicenter study to assess the incidence of and factors related to the recurrence of AA after EP in patients with familial adenomatous polyposis (FAP) compared to sporadic AA. METHODS We included patients who underwent EP for AA at 10 tertiary hospitals. Adenomatous tissue at the resection site at the time of surveillance endoscopies was considered recurrent disease. RESULTS In all, 257 patients, 100 (38.9%) with FAP and 157 (61%) patients with sporadic AA, were included. Over a median of 31 (range, 11-61) months, recurrence occurred in 48/100 (48%) of patients with FAP and 58/157 (36.9%) with sporadic AA (P = 0.07). Two (2%) FAP patients and 10 (6.3%) patients with sporadic AA underwent surgery for recurrence. On multivariable regression analysis, the recurrence in FAP was higher than in sporadic patients after the first year of follow-up. AA size (hazard ratio [HR] 1.03, 95% confidence interval [CI] 1.001, 1.056), periampullary extension (HR 2.5, 95% CI 1.5, 4.01), and biliary duct dilation (HR 2.04, 95% CI 1.2, 3.4) increased the risk, while en bloc resection (HR 0.6, 95% CI 0.41, 0.9) decreased the risk of recurrence. CONCLUSION Recurrence rates are high after EP. Most recurrences in sporadic patients occur within the first year of follow-up, but after the first year of follow-up in patients with FAP. Recurrences are higher with larger adenomas, biliary duct dilation, and periampullary extensions, and may be mitigated by en bloc resection. These factors should be considered in decision-making with the patients.

Abstract
BACKGROUND Consequences of physician burnout include medical errors, higher rate of staff turnover, and decreased patient satisfaction. We examined the prevalence of burnout and identified the contributing factors in gastroenterologists and fellows in training. METHODS We performed 3 separate surveys through the American College of Gastroenterology. (1) A national survey of practicing gastroenterologists in the United States that measured burnout and contributing factors, (2) a survey of gastroenterology fellows in training to determine self-identified burnout, as well as mitigating and exacerbating factors, and (3) a follow-up survey of fellows during the COVID-19 pandemic. RESULTS One thousand and twenty-one persons responded (9.2% response rate) to the first survey, including 756 individuals who completed the Maslach Burnout Inventory survey. Overall, the prevalence of high burnout was 49.3%. Factors associated with high burnout included female sex, younger age, shorter duration in practice, considering the electronic health record non-user-friendly, 2 or more hours of patient-related work at home per day, 8 or more hours of outpatient time per day, 6 or more inpatient consults per day, taking call with procedures 10 or more times per year, and having children at home. With regard to lifestyle factors, taking 20 days or more of vacation time was associated with a lower rate of burnout. The level of burnout for fellows was observed to be high (42.7% in survey 2 and 35.3% in survey 3). CONCLUSIONS Burnout is high in gastroenterologists and fellows in training. Specific contributing factors were both systems based and personal and provide insight into changes that can be made to address burnout.

[PMID: 37356633 DOI: 10.1016/j.gie.2023.06.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/09/2023] [Revised: 05/13/2023] [Accepted: 06/11/2023] [Indexed: 06/27/2023]
Abstract
BACKGROUND AND AIMS Colonoscopy quality affects colorectal cancer (CRC) incidence and mortality. The U.S. Multi-Society Task Force on Colorectal Cancer strongly recommends photodocumentation (PD) of lesions ≥10 mm in size (ie, large polyps [LPs]) pre-resection and suggests PD postresection to enhance the quality of colonoscopy. No studies have assessed the frequency of LP PD. We evaluated the frequency of and factors associated with PD of LPs. METHODS Reports from endoscopists performing ≥50 colonoscopies with LP resection between 2016 and 2021 were reviewed. The frequency of LP PD pre-resection and post-resection and factors associated with PD were collected. A composite score of 2 quality metrics (PD of completeness of examination and bowel preparation quality) was created. Endoscopists were divided into 2 tiers based on the frequency of the score on all included examinations: Tier 1, ≥95% of examinations; and Tier 2, <95% of examinations. Univariate and multivariate analyses were used to assess factors associated with PD. RESULTS A total of 1322 colonoscopies, 1693 LPs, and 25 endoscopists were included in this study. PD of LPs occurred in 1392 (82%) pre-resection and in 878 (52%) post-resection. Factors associated with pre-resection PD include endoscopist subspecialty (colorectal surgery vs gastroenterology: odds ratio [OR], .12; 95% confidence interval [CI], .04-.42); >1 LP on examination (2 vs 1 LP: OR, .41 [95% CI, .27-.61]; and ≥3 vs 1 LP: OR, .41 [95% CI, .24-.70]), and longer withdrawal time (OR, 1.02; 95% CI, 1.01-1.04). CONCLUSIONS We provide the first data on PD of LP pre-resection and post-resection, which can inform future benchmarking in this area. The implications of PD on metachronous advanced neoplasia need to be studied.

Referral, Uptake, and Outcome of Genetic Counseling and Testing in Patients With Early-Onset Colorectal Cancer. J Natl Compr Canc Netw 2023; 21:1156-1163.e5. [PMID: 37935108 DOI: 10.6004/jnccn.2023.7057] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2023] [Accepted: 07/11/2023] [Indexed: 11/09/2023]
Abstract
BACKGROUND The incidence of early-onset colorectal cancer (EOCRC) is rapidly increasing. Pathogenic germline variants (PGVs) are detected in 16% to 20% of patients who have EOCRC, highlighting a need for genetic counseling (GC) and multigene panel testing in these patients. We aimed to determine the rate of referral to GC and uptake and outcomes of germline testing in patients with EOCRC. METHODS We conducted a retrospective cohort study of patients aged <50 years diagnosed with colorectal cancer (CRC) from 2010 to 2019 at Cleveland Clinic. Demographic data were extracted, including age, sex, self-reported race, and family history of CRC. The proportions of patients with GC referral and completion of GC and genetic testing were investigated, and genetic testing results were analyzed. Multivariable logistic regression analysis was conducted to identify factors independently associated with GC referral and uptake. RESULTS A total of 791 patients with EOCRC (57% male and 43% female) were included; 62% were referred for GC, and of those who were referred, 79% completed a GC appointment and 77% underwent genetic testing. Of those who underwent testing, 21% had a PGV detected; 82% were in known CRC-associated genes, with those associated with Lynch syndrome and familial adenomatous polyposis the most common, and 11% were in other actionable genes. Referral to GC was positively associated with family history of CRC (odds ratio [OR], 2.11; 95% CI, 1.51-2.96) and more recent year of diagnosis (2010-2013 vs 2017-2019; OR, 5.36; 95% CI, 3.59-8.01) but negatively associated with older age at diagnosis (OR, 0.89; 95% CI, 0.86-0.92). CONCLUSIONS Referral to GC for patients with EOCRC is increasing over time; however, even in recent years, almost 25% of patients were not referred for GC. We found that 1 in 5 patients with EOCRC carry actionable PGVs, highlighting the need for health systems to implement care pathways to optimize GC referral and testing in all patients with EOCRC.

Incidence and prevalence of advanced colorectal neoplasia in Lynch syndrome. Gastrointest Endosc 2023; 98:412-419.e8. [PMID: 37031913 DOI: 10.1016/j.gie.2023.04.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2023] [Revised: 02/24/2023] [Accepted: 04/04/2023] [Indexed: 04/11/2023]
Abstract
BACKGROUND AND AIMS Lynch syndrome (LS) is the most common hereditary cause of colorectal cancer (CRC) and endometrial cancer (EC). Although colonoscopy reduces CRC in LS, the protection is variable. We assessed the prevalence and incidence of neoplasia in LS during surveillance colonoscopy in the United States and factors associated with advanced neoplasia. METHODS Patients with LS undergoing ≥1 surveillance colonoscopy and with no personal history of invasive CRC or colorectal surgery were included. Prevalent and incident neoplasia was defined as occurring <6 months before and ≥6 months after germline diagnosis of LS, respectively. We assessed advanced adenoma (AA), CRC, and the impact of mismatch repair pathogenic variant (PV) and typical LS cancer history (personal history of EC and/or family history of EC/CRC) on outcome. RESULTS A total of 132 patients (inclusive of 112 undergoing prevalent and incident surveillance) were included. The median examination interval and duration of prevalent and incident surveillance was .88 and 1.06 years and 3.1 and 4.6 years, respectively. Prevalent and incident AA were detected in 10.7% and 6.1% and invasive CRC in 0% and 2.3% of patients. All incident CRC occurred in MSH2 and MLH1 PV carriers and only 1 (.7%) while under surveillance in our center. AAs were detected in both LS cancer history cohorts and represented in all PVs. CONCLUSIONS In a U.S. cohort of LS, advanced neoplasia rarely occurred over annual surveillance. CRC was diagnosed only in MSH2/MLH1 PV carriers. AAs occurred regardless of PV or LS cancer history. Prospective studies are warranted to confirm our findings.

Upper Gastrointestinal Neoplasia and Worrisome Thyroid Nodules are Common in Colonic Polyposis of Unknown Etiology (CPUE). J Clin Gastroenterol 2023:00004836-990000000-00201. [PMID: 37646505 DOI: 10.1097/mcg.0000000000001911] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/21/2023] [Accepted: 07/19/2023] [Indexed: 09/01/2023]
Abstract
BACKGROUND Colonic polyposis of unknown etiology (CPUE) is defined as ≥10 cumulative colonic adenomas without a detectable germline pathogenic variant. Surveillance for patients with >100 adenomas is recommended, similar to patients with familial adenomatous polyposis. The utility of extra-colonic screening in patients with 10 to <100 adenomas is not well established. METHODS All CPUE patients seen at our center between 2003 and 2022 were included. Patients were categorized based on the range of cumulative colorectal adenoma count: 10 to 19, 20 to 99, and ≥100. RESULTS In all, 150 patients were identified of which 20(13.3%) had 10 to 19 cumulative adenomas, 79(52.7%) had 20 to 99 adenomas, and 51(34.0%) had ≥100 adenomas. Compared with patients with 10 to 19 and 20 to 99, patients with ≥100 adenomas were younger (mean 51 vs. 52 vs. 42 y, respectively). Of patients who underwent esophagogastroduodenoscopy, duodenal adenomas were found in 33.3%, 10.1%, and 38% in the 3 groups, respectively, P=0.002. Ampullary adenomas were significantly more common in the ≥100 adenoma group (14.8%, P=0.019) compared with 8.3% and 2.9% in the 10 to 19 and 20 to 99 groups, respectively. Thyroid nodules ≥1 cm were not detected in patients with 10 to 19 adenomas but were found in 23.3% and 14.3% of patients with 20 to 99 and ≥100 adenomas, respectively (P=0.254). CONCLUSION In our cohort, duodenal and gastric adenomas occurred in CPUE patients with adenoma count 10 to ≥100 at a relatively high proportion. We recommend a baseline esophagogastroduodenoscopy in all patients with CPUE. While clinically significant thyroid nodules were not detected in patients with 10 to 19 adenomas, they occurred in about one-fifth of the patients with ≥20 adenomas, indicating that thyroid ultrasound is prudent.

Impact of Clinical and Endoscopic Features on the Development of Metachronous Colorectal Advanced Serrated Lesions. Clin Gastroenterol Hepatol 2023:S1542-3565(23)00587-6. [PMID: 37544421 DOI: 10.1016/j.cgh.2023.07.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/12/2023] [Revised: 07/23/2023] [Accepted: 07/25/2023] [Indexed: 08/08/2023]
Abstract
BACKGROUND AND AIMS High-risk adenomas predict metachronous advanced adenomatous neoplasia. Limited data exist on predictors of metachronous advanced serrated lesions (mASLs). We analyzed clinical and endoscopic predictors of mASLs. METHODS In this retrospective cohort study, adults with >1 outpatient colonoscopy between 2008 and 2019 at a tertiary center were included. Serrated lesions (SLs) included sessile SLs (SSLs), traditional serrated adenomas (TSAs), and hyperplastic polyps (HPs). Patient and endoscopic characteristics were obtained using electronic medical records. Five-year cumulative incidence of mASL (HP ≥10 mm, SSL ≥10 mm or with dysplasia, any TSA) and factors associated with mASL were evaluated using Kaplan-Meier estimates and Cox proportional hazards models. RESULTS A total of 4990 patients were included and 45.4% were women. Mean age was 60.9 ± 9.2 years and median follow-up time was 3.7 years. Female sex and active smoking were associated with mASL. Endoscopically, any SSL and TSA were associated with mASL. The 5-year cumulative incidence for mASL was 26% (95% confidence interval [CI], 18%-32%) for SSL ≥10 mm, 17% (95% CI, 3.5%-29%) for HP ≥10 mm, 21% (95% CI, 0%-42%) for 3-4 SSLs <10 mm, 18% (95% CI, 0%-38%) for TSA, and 27% (95% CI, 3.6%-45%) for SSL with low-grade dysplasia. Baseline synchronous nonadvanced SL and nonadvanced adenoma were not associated with mASL. CONCLUSIONS Our data support current recommendations for a 3-year surveillance interval in patients with baseline SSL ≥10 mm, SSL with dysplasia, and TSA. A 3-year interval may be more appropriate than 3-5 years for patients with baseline HP ≥10 mm or 3-4 SSLs <10 mm. Patients with synchronous nonadvanced SLs and adenomas do not appear to be at increased risk of mASL.

Abstract
Importance The benefits from colorectal cancer (CRC) screening may take 10 to 15 years to accrue. Therefore, screening is recommended for older adults who are in good health. Objective To determine the number of screening colonoscopies done in patients older than 75 years with a life expectancy of fewer than 10 years, diagnostic yield, and associated adverse events within 10 days and 30 days of the procedure. Design This cross-sectional study with a nested cohort between January 2009 and January 2022 in an integrated health system assessed asymptomatic patients older than 75 years who underwent screening colonoscopy in the outpatient setting. Reports with incomplete data, any indication other than screening, patients who had a colonoscopy within the previous 5 years, and patients with a personal history of inflammatory bowel disease or CRC were excluded. Exposures Life expectancy based on a prediction model from previous literature. Main Outcomes and Measures The primary outcome was the percentage of screened patients who had limited (<10 years) life expectancy. Other outcomes included colonoscopy findings and adverse events that developed within 10 days and 30 days of the procedure. Results A total of 7067 patients older than 75 years were included. The median (IQR) age was 78 (77-79) years, 3967 (56%) were women, and 5431 (77%) were White with an average of 2 comorbidities (taken from a select group of comorbidities). The proportion of colonoscopies performed on patients with a life expectancy of fewer than 10 years aged 76 to 80 years was 30% in both sexes and increased with age-82% of men and 61% of women aged 81 to 85 years (71% total), and 100% of patients beyond the age of 85 years. Adverse events requiring hospitalizations were common at 10 days (13.58 per 1000) and increased with age, particularly among patients older than 85 years. The detection of advanced neoplasia varied from 5.4% among patients aged 76 to 80 years to 6.2% in those aged 81 to 85 years and 9.5% among patients older than 85 years (P = .02). Of the total population, 15 patients (0.2%) had invasive adenocarcinoma; among patients with a life expectancy of fewer than 10 years, 1 of 9 was treated, whereas 4 of 6 patients with a life expectancy of greater than or equal to 10 years were treated. Conclusions and Relevance In this cross-sectional study with a nested cohort, most screening colonoscopies performed in patients older than 75 years were in patients with limited life expectancy and associated with increased risk of complications. Colorectal cancer was exceedingly rare.

Abstract
Importance Identifying hereditary cancer predisposition facilitates high-risk organ-specific cancer surveillance and prevention. In PTEN hamartoma tumor syndrome (PHTS), longitudinal studies remain lacking, and there are insufficient data on cancers in children and young adults, as well as individuals with neurodevelopmental disorders (NDD). Objective To evaluate lifetime cancer risks, including second malignant neoplasms (SMN), among patients with PHTS. Design, Setting, and Participants Prospective longitudinal cohort study (September 1, 2005, through January 6, 2022). General population risks from the Surveillance, Epidemiology, and End Results database. Patients with PHTS, molecularly defined as carrying germline PTEN variants, were accrued from community and academic medical centers throughout North America, South America, Europe, Australia, and Asia. Data were analyzed from July 2022 to February 2023. Exposures Review of physical and electronic medical records, and follow-up through clinical visits or telephone interviews. Main Outcomes and Measures Lifetime cancer risks in PHTS relative to the general population. Results A total of 7302 patients were prospectively accrued, 701 of whom had germline PTEN variants (median [IQR] age at consent, 38 [12-52] years; 413 female patients [59%]). Longitudinal follow-up data could be obtained for 260 patients (37%), with a median (IQR) follow-up of 4 (2-8) years. Of the 701 patients, 341 (49%) received at least 1 cancer diagnosis, with 144 (42%) of those having SMN. The study found significantly elevated lifetime risks for breast (91%), endometrial (48%), thyroid (33%), kidney (30%), and colorectal cancers (17%), as well as melanoma (5%). Cancer diagnoses were also observed in children and young adults with PHTS (15%) and in patients with PHTS with neurodevelopmental disorders (11%). Elevated risks (P < .001) of thyroid (age-adjusted standardized incidence ratios [SIR], 32.1; 95% CI, 26.0-39.0), kidney (SIR, 26.5; 95% CI, 18.8-36.3), endometrial (SIR, 26.0; 95% CI, 19.5-34.1), breast (SIR, 20.3; 95% CI, 17.3-23.7), and colorectal (SIR, 7.9; 95% CI, 5.2-11.7) cancers, and melanoma (SIR, 6.3; 95% CI, 3.5-10.5) were observed. Of the 341 patients with PHTS with cancer, 51 (15%) had 1 or more cancers diagnosed at age 29 years or younger, and 16 (31.4%) of those developed SMN at final follow-up. Twenty-three patients with PHTS with NDD and cancer were identified, with 5 (22%) having developed SMN at final follow-up. Individuals with PHTS and NDD showed higher lifetime cancer risks compared with individuals with PHTS but without NDD (hazard ratio, 2.7; 95% CI, 1.7-4.2; P < .001). Conclusions and Relevance This cohort study found consistently elevated lifetime cancer risks in PHTS. Organ-specific surveillance should continue in patients with PHTS. Additional study is required to ascertain elevated cancer risks in patients with PHTS with NDD.

Abstract
BACKGROUND & AIMS Patients with early-onset colorectal cancer (eoCRC) are managed according to guidelines that are not age-specific. A multidisciplinary international group (DIRECt), composed of 69 experts, was convened to develop the first evidence-based consensus recommendations for eoCRC. METHODS After reviewing the published literature, a Delphi methodology was used to draft and respond to clinically relevant questions. Each statement underwent 3 rounds of voting and reached a consensus level of agreement of ≥80%. RESULTS The DIRECt group produced 31 statements in 7 areas of interest: diagnosis, risk factors, genetics, pathology-oncology, endoscopy, therapy, and supportive care. There was strong consensus that all individuals younger than 50 should undergo CRC risk stratification and prompt symptom assessment. All newly diagnosed eoCRC patients should receive germline genetic testing, ideally before surgery. On the basis of current evidence, endoscopic, surgical, and oncologic treatment of eoCRC should not differ from later-onset CRC, except for individuals with pathogenic or likely pathogenic germline variants. The evidence on chemotherapy is not sufficient to recommend changes to established therapeutic protocols. Fertility preservation and sexual health are important to address in eoCRC survivors. The DIRECt group highlighted areas with knowledge gaps that should be prioritized in future research efforts, including age at first screening for the general population, use of fecal immunochemical tests, chemotherapy, endoscopic therapy, and post-treatment surveillance for eoCRC patients. CONCLUSIONS The DIRECt group produced the first consensus recommendations on eoCRC. All statements should be considered together with the accompanying comments and literature reviews. We highlighted areas where research should be prioritized. These guidelines represent a useful tool for clinicians caring for patients with eoCRC.

Abstract
BACKGROUND & AIMS Despite the high prevalence of asymptomatic gallstones (AGs), there are limited data on their natural history. We aimed to determine the rate of symptom development in a contemporary population, determine factors associated with progression to symptomatic gallstones (SGs), and develop a clinical prediction model. METHODS We used a retrospective cohort design. The time to first SG was shown using Kaplan-Meier curves. Multivariable competing risk (death) regression analysis was used to identify variables associated with SGs. A prediction model for the development of SGs after 10 years was generated and calibration curves were plotted. Participants were patients with AGs based on ultrasound or computed tomography from the general medical population. RESULTS From 1996 to 2016, 22,257 patients (51% female) with AGs were identified; 14.5% developed SG with a median follow-up period of 4.6 years. The cumulative incidence was 10.1% (±0.22%) at 5 years, 21.5% (±0.39%) at 10 years, and 32.6% (±0.83%) at 15 years. In a multivariable model, the strongest predictors of developing SGs were female gender (hazard ratio [HR], 1.50; 95% CI, 1.39-1.61), younger age (HR per 5 years, 1.15; 95% CI, 1.14-1.16), multiple stones (HR, 2.42; 95% CI, 2.25-2.61), gallbladder polyps (HR, 2.55; 95% CI, 2.14-3.05), large stones (HR, 2.03; 95% CI, 1.80-2.29), and chronic hemolytic anemia (HR, 1.90; 95% CI, 1.33-2.72). The model showed good discrimination (C-statistic, 0.70) and calibration. CONCLUSIONS In general medical patients with AGs, symptoms developed at approximately 2% per year. A predictive model with good calibration could be used to inform patients of their risk of SGs.

Abstract
IMPORTANCE Patients with familial adenomatous polyposis (FAP) are at markedly increased risk for duodenal adenomas and cancer. Combination sulindac and erlotinib was previously shown to reduce duodenal polyp burden but was associated with a relatively high adverse event (AE) rate. OBJECTIVE To evaluate if a once weekly dosing schedule for erlotinib intervention improves the AE profile, while still providing efficacy with respect to reduced polyp burden, in participants with FAP. DESIGN, SETTING AND PARTICIPANTS Single-arm trial, enrolling 46 participants with FAP, conducted from October 2017 to September 2019 in eight academic cancer centres. EXPOSURES Participants self-administered 350 mg of erlotinib by mouth, one time per week for 6 months. MAIN OUTCOMES AND MEASURES Duodenal polyp burden (sum of polyp diameters) was assessed in the proximal duodenum by esophagogastroduodenoscopy performed at baseline and 6 months, with mean per cent change defined as the primary efficacy outcome of interest. Rate of grade 2-3 AEs was evaluated as a co-primary outcome. Secondary outcomes included changes in total duodenal polyp count, along with changes in lower gastrointestinal (GI) polyp burden and count (for participants examined by optional lower endoscopy). RESULTS Forty-six participants (mean age, 44.1 years (range, 18-68); women, 22 (48%)) were enrolled; 42 participants completed 6 months of intervention and were included in the per-protocol analysis. Duodenal polyp burden was significantly reduced after 6 months of weekly erlotinib intervention, with a mean per cent change of -29.6% (95% CI, -39.6% to -19.7%; p<0.0001). Similar results were observed in subgroup analyses defined by participants with advanced duodenal polyposis (Spigelman 3) at baseline (mean, -27%; 95% CI, -38.7% to -15.2%; p<0.0001). Post-intervention Spigelman stage was downstaged in 12% of the participants. Lower GI polyp number was also decreased after 6 months of intervention (median, -30.8%; IQR, -47.4% to 0.0%; p=0.0256). Grade 2 or 3 AEs were reported in 71.7% of subjects, with only two experiencing grade 3 toxicity at least possibly related to intervention. CONCLUSION In this single-arm, multi-centre trial of participants with FAP, erlotinib one time per week resulted in markedly lower duodenal polyp burden, and modestly reduced lower GI polyp burden, after 6 months of intervention. While AEs were still reported by nearly three-quarters of all participants, these events were generally lower grade and well-tolerated. These findings support further investigation of erlotinib as an effective, acceptable cancer preventive agent for FAP-associated GI polyposis. TRIAL REGISTRATION NUMBER NCT02961374.

Identifying factors associated with detection of sessile gastric polyps in patients with familial adenomatous polyposis. Endosc Int Open 2022; 10:E1080-E1087. [PMID: 35979026 PMCID: PMC9377824 DOI: 10.1055/a-1839-5185] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Accepted: 04/25/2022] [Indexed: 11/20/2022] Open
Abstract
Background and study aims Gastric cancer (GC) is increasingly reported and a leading cause of death in patients with familial adenomatous polyposis (FAP). Identifying features in patients with FAP who harbor sessile gastric polyps, likely precursors to GC, may lead to alterations in endoscopic surveillance in those patients and allow endoscopic intervention to decrease the risk of GC. The aim of this study was to identify demographic and clinical factors in patients with FAP who harbor sessile gastric polyps. Patients and methods We retrospectively compared demographic, clinical, and endoscopic features in consecutive adult patients with FAP who presented for a surveillance endoscopy at a tertiary-care center with a FAP registry who harbor sessile gastric polyps to those without them. Sessile gastric polyps included pyloric gland adenomas, gastric adenomas, hyperplastic polyps, and fundic gland polyps with high-grade dysplasia. We also display the location of germline APC pathogenic variants in patients with and without sessile gastric polyps. Results Eighty patients with FAP were included. Their average age was 48 years and 70 % were male . Nineteen (24 %) had sessile gastric polyps. They were older ( P < 0.03), more likely to have a family history of GC ( P < 0.05), white mucosal patches in the proximal stomach ( P < 0.001), and antral polyps ( P < 0.026) compared to patients without a gastric neoplasm. No difference in Spigelman stage, extra-intestinal manifestations, or surgical history was note. 89 % of patients with a gastric neoplasm had an APC pathogenic variant 5' to codon 1309. Conclusions Specific demographic, endoscopic, and genotypic features are associated with patients with FAP who harbor sessile gastric polyps. We recommend heightened awareness of these factors when performing endoscopic surveillance of the stomach with resection of gastric neoplasia when identified.

Endoscopy-related injury among gastroenterology trainees. Endosc Int Open 2022; 10:E1095-E1104. [PMID: 36032041 PMCID: PMC9403520 DOI: 10.1055/a-1869-9202] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/15/2022] [Accepted: 05/31/2022] [Indexed: 11/26/2022] Open
Abstract
Background and study aims Endoscopy-related injury (ERI) is widespread among practicing gastroenterologists. However, less is known about the incidence among trainees. This study assesses the rate of self-reported ERI occurrence, patterns of injury, and knowledge of preventive strategies in a nationally representative sample of gastroenterology fellows. Methods A 38-item electronic survey was sent to members of the American College of Gastroenterology. One hundred and sixty-eight gastroenterology fellows were included in analyses. Descriptive and univariate analyses evaluated the likelihood of ERI by workload parameters and gender. Results ERI was reported by 54.8 % of respondents. ERI was most common in the thumb (58.7 %), hand/finger (56.5 %), and wrist (47.8 %). There was no significant difference in the reported occurrence of ERI between male and female gastroenterology fellows. However, female fellows were significantly more likely to report a greater number of body areas affected by ERI, and male fellows were more likely to report elbow pain. Most respondents (85.1 %) reported discussion about, or training in, ergonomic strategies during gastroenterology fellowship. Conclusions ERI is reported to occur as early as gastroenterology fellowship. Results of this study support this finding and highlight the need for ongoing implementation and monitoring of a formal ergonomics training program as well as development of ergonomically appropriate instruments. Implications of these findings likely extend to trainees in other procedural related specialties like orthopedics and general surgery, though further research is required. Ergonomics training in gastroenterology fellowship and monitoring of its impact on trainees reported ERI is important due to negative effects on productivity and career longevity.

Abstract
The gastrointestinal hamartomatous polyposis syndromes are rare, autosomal dominant disorders associated with an increased risk of benign and malignant intestinal and extraintestinal tumors. They include Peutz-Jeghers syndrome, juvenile polyposis syndrome, the PTEN hamartoma tumor syndrome (including Cowden's syndrome and Bannayan-Riley-Ruvalcaba syndrome), and hereditary mixed polyposis syndrome. Diagnoses are based on clinical criteria and, in some cases, confirmed by demonstrating the presence of a germline pathogenic variant. The best understood hamartomatous polyposis syndrome is Peutz-Jeghers syndrome, caused by germline pathogenic variants in the STK11 gene. The management is focused on prevention of bleeding and mechanical obstruction of the small bowel by polyps and surveillance of organs at increased risk for cancer. Juvenile polyposis syndrome is caused by a germline pathogenic variant in either the SMAD4 or BMPR1A genes, with differing clinical courses. Patients with SMAD4 pathogenic variants may have massive gastric polyposis, which can result in gastrointestinal bleeding and/or protein-losing gastropathy. Patients with SMAD4 mutations usually have the simultaneous occurrence of hereditary hemorrhagic telangiectasia (juvenile polyposis syndrome-hereditary hemorrhagic telangiectasia overlap syndrome) that can result in epistaxis, gastrointestinal bleeding from mucocutaneous telangiectasias, and arteriovenous malformations. Germline pathogenic variants in the PTEN gene cause overlapping clinical phenotypes (known as the PTEN hamartoma tumor syndromes), including Cowden's syndrome and related disorders that are associated with an increased risk of gastrointestinal and colonic polyposis, colon cancer, and other extraintestinal manifestations and cancers. Due to the relative rarity of the hamartomatous polyposis syndromes, recommendations for management are based on few studies. This U.S Multi-Society Task Force on Colorectal Cancer consensus statement summarizes the clinical features, assesses the current literature, and provides guidance for diagnosis, assessment, and management of patients with the hamartomatous polyposis syndromes, with a focus on endoscopic management.

Abstract
Objectives Familial adenomatous polyposis (FAP) patients with Spigelman stage IV polyposis should be considered for prophylactic duodenectomy. Post‐surgical pancreaticobiliary complications occur and may require management via endoscopic retrograde cholangiopancreatography (ERCP). We aimed to assess the success and adverse events of ERCP in FAP patients after pancreas‐sparing duodenectomy (PSD) and pancreaticoduodenectomy (PD). Methods A retrospective review of FAP patients who underwent ERCP after PSD or PD from 1992 to 2020 at a quaternary referral center was completed. The technical success of ERCP was defined as the ability to identify the anastomosis and cannulate the duct. Post‐procedural adverse events were defined by bleeding, perforation, pancreatitis, or cholangitis. Clinical outcomes included the need for surgical intervention and recurrent pancreatitis after ERCP were assessed. Results Of 84 FAP patients with duodenectomy, 12 patients with PSD and two patients with PD underwent 17 ERCPs for pancreatic indications and five for biliary indications. The technical success of ERCP in patients with PSD and a single neoampullary complex for pancreatic (n = 6) and biliary (n = 5) indications was 100% but for those with PD (n = 2) or PSD reconstruction with pancreatic divisum or separate anastomoses (n = 3), it was 0%. Surgical intervention was required in 50% of patients with technically failed ERCP after PSD (2/4) and PD (1/2). There were no adverse events. Conclusions ERCP is expected to be therapeutically successful for biliary complications following PSD. Assessment and potential therapy for pancreatitis post‐PSD are best in the setting of a single neo‐ampullary complex rather than in PD or PSD with pancreatic divisum.

Abstract
GOALS AND BACKGROUND Phosphatase and tensin homolog hamartoma tumor syndrome (PHTS) is an inherited disorder that increases the risk for cancer in multiple organ systems, including breast, endometrial, thyroid, and the gastrointestinal tract. Surveillance is recommended however there lacks data to describe the change in polyposis phenotype and cancer incidence over surveillance. Our aim is to describe the polyposis phenotype and cancer incidence in PHTS patients undergoing endoscopic surveillance. STUDY PHTS patients, ages 17 through 89, who underwent at least 2 esophagogastroduodenoscopy (EGDs) or colonoscopies were identified. Number and sizes of polyps were noted, from which 5 categories were recreated. Incidence of colorectal and gastric cancer was evaluated. RESULTS Seventy patients were included. Patients were clustered and classified into 1 of 5 categories: no polyps, few small polyps (<1 cm, < 10 polyps), few large polyps (≥1 cm, < 10 polyps), many small polyps (<1 cm, ≥10 polyps), many large polyps (≥1 cm, ≥10 polyps). There was no significant difference in polyp number or size on EGD (P=0.47 and 0.83, respectively) or colonoscopy (P=0.49 and 0.10, respectively) over the surveillance period (4.8±3.9 y for stomach and 5.6±4.4 y for colon). The average interval between endoscopies was 28±24 months for EGDs and 29±23 months for colonoscopies. A stage II transverse colon adenocarcinoma and stage IV gastric adenocarcinoma were identified. Standardized incidence rates for gastric and colon cancers were 5427 (P=0.0002) and 353 (P=0.002), respectively. CONCLUSIONS PTHS individuals can be classified into polyposis phenotypes which do not change over an endoscopic surveillance period. Two cancers were associated with a large size polyp phenotype. Surveillance intervals should be determined by polyp size ≥1 cm and pathology.

Abstract
BACKGROUND Individuals with Lynch syndrome (LS) and hereditary non-polyposis colorectal cancer (HNPCC) are at increased risk of both colorectal cancer and other cancers. The interplay between immunosuppression, a comorbid inflammatory condition (CID), and HNPCC on cancer risk is unclear.
AIM To evaluate the impact of CIDs, and exposure to monoclonal antibodies and immunomodulators, on cancer risk in individuals with HNPCC.
METHODS Individuals prospectively followed in a hereditary cancer registry with LS/HNPCC with the diagnosis of inflammatory bowel disease or rheumatic disease were identified. We compared the proportion of patients with cancer in LS/HNPCC group with and without a CID. We also compared the proportion of patients who developed cancer following a CID diagnosis based upon exposure to immunosuppressive medications.
RESULTS A total of 21 patients with LS/HNPCC and a CID were compared to 43 patients with LS/HNPCC but no CID. Cancer occurred in 84.2% with a CID compared to 76.7% without a CID (P = 0.74) with no difference in age at first cancer diagnosis 45.5 ± 14.6 vs 43.8 ± 7.1 years (P = 0.67). LS specific cancers were diagnosed in 52.4% with a CID vs 44.2% without a CID (P = 0.54). Nine of 21 (42.9%) patients were exposed to biologics or immunomodulators for the treatment of their CID. Cancer after diagnosis of CID was seen in 7 (77.8%) of exposed individuals vs 5 (41.7%) individuals unexposed to biologics/immunomodulators (P = 0.18). All 7 exposed compared to 3/5 unexposed developed a LS specific cancer. The exposed and unexposed groups were followed for a median 10 years and 8.5 years, respectively. The hazard ratio for cancer with medication exposure was 1.59 (P = 0.43, 95%CI: 0.5-5.1).
CONCLUSION In patients with LS/HNPCC, the presence of a concurrent inflammatory condition, or use of immunosuppressive medication to treat the inflammatory condition, might not increase the rate of cancer occurrence in this limited study.

Abstract
Secondary prevention of colorectal neoplasia with chemoprevention is long-studied area of research and clinical use in patients with the 2 most common hereditary colorectal cancer syndromes including Lynch syndrome and familial adenomatous polyposis. No medication is currently approved for use for the prevention of colorectal polyps or cancer in either the general population or individuals with the hereditary colorectal cancer syndromes. Emerging data in animal models and limited data in humans suggest vaccines may be the next breakthrough for neoplasia prevention in patients with hereditary colorectal cancer. Clinicians must acknowledge chemoprevention is an adjunct and does not supplant endoscopic surveillance.

Abstract
This document is a focused update to the 2017 colorectal cancer (CRC) screening recommendations from the U.S. Multi-Society Task Force on Colorectal Cancer, which represents the American College of Gastroenterology, the American Gastroenterological Association, and the American Society for Gastrointestinal Endoscopy. This update is restricted to addressing the age to start and stop CRC screening in average-risk individuals and the recommended screening modalities. Although there is no literature demonstrating that CRC screening in individuals under age 50 improves health outcomes such as CRC incidence or CRC-related mortality, sufficient data support the U.S. Multi-Society Task Force to suggest average-risk CRC screening begin at age 45. This recommendation is based on the increasing disease burden among individuals under age 50, emerging data that the prevalence of advanced colorectal neoplasia in individuals ages 45 to 49 approaches rates in individuals 50 to 59, and modeling studies that demonstrate the benefits of screening outweigh the potential harms and costs. For individuals ages 76 to 85, the decision to start or continue screening should be individualized and based on prior screening history, life expectancy, CRC risk, and personal preference. Screening is not recommended after age 85.

Abstract
Identifying individuals with hereditary syndromes allows for timely cancer surveillance, opportunities for risk reduction, and syndrome-specific management. Establishing criteria for hereditary cancer risk assessment allows for the identification of individuals who are carriers of pathogenic genetic variants. The NCCN Guidelines for Genetic/Familial High-Risk Assessment: Colorectal provides recommendations for the assessment and management of patients at risk for or diagnosed with high-risk colorectal cancer syndromes. The NCCN Genetic/Familial High-Risk Assessment: Colorectal panel meets annually to evaluate and update their recommendations based on their clinical expertise and new scientific data. These NCCN Guidelines Insights focus on familial adenomatous polyposis (FAP)/attenuated familial adenomatous polyposis (AFAP) syndrome and considerations for management of duodenal neoplasia.

Abstract
BACKGROUND Selecting a bowel preparation for patients with renal impairment or diabetes requires special consideration. We aimed to describe the effect of baseline renal impairment or diabetes on the safety, efficacy, and tolerability of low-volume sodium picosulfate, magnesium oxide, and citric acid (SPMC) ready-to-drink oral solution bowel preparation. METHODS A post hoc secondary analysis was performed from a randomized, assessor-blinded study of SPMC oral solution bowel preparation in participants with mild or moderate baseline renal impairment or diabetes. Primary efficacy endpoint ('responders') was the proportion of participants with 'excellent' or 'good' ratings on a modified Aronchick Scale (AS). Secondary efficacy outcomes were the quality of ascending colon cleansing from the Boston Bowel Preparation Scale (BBPS), and selected results from the Mayo Clinic Bowel Prep Tolerability Questionnaire. Safety assessments included adverse events (AEs), adenoma detection, and laboratory evaluations. RESULTS Similar overall colon cleansing was demonstrated in the subgroups, with >85% of participants in any subgroup rated as responders by the AS, and >92% of participant responders by the BBPS. Most participants reported a tolerable bowel preparation, regardless of baseline renal impairment or diabetes history. Safety of SPMC oral solution was similar between all subgroups and the overall cohort. For the mild renal impairment, moderate renal impairment, and diabetes subgroups, respectively, commonly reported, drug-related AEs were nausea (2.6%, 5.3%, 1.4%) and headache (2.2%, 2.6%, 4.3%). CONCLUSIONS Ready-to-drink SPMC oral solution demonstrated efficacious colon cleansing in patients with baseline mild/moderate renal impairment or diabetes, with a tolerable bowel preparation reported by most.

Abstract
BACKGROUND AND AIMS Some data suggest that individuals with numerous, <10-mm, rectosigmoid hyperplastic polyps (HPs) are at average risk for the development of metachronous advanced adenomatous neoplasia. Guidelines suggest that these individuals do not need surveillance colonoscopy and should be followed akin to individuals with a normal colonoscopy. Less is known of the risk of metachronous neoplasia because of ≥1 HPs <10 mm proximal to the sigmoid colon. We compared the risk of metachronous neoplasia between individuals with small HPs and those with normal colonoscopy, specifically addressing the impact of location and number of HPs on risk. METHODS Colonoscopy and pathology reports from patients with ≥2 colonoscopies between 2004 and 2014 were reviewed. Exclusions included inpatients; age <40 or >75 years; and family or personal history of colorectal cancer, inflammatory bowel disease, previous colorectal surgery, or a previous colonoscopy with any adenoma, sessile serrated lesion (SSL), or HP ≥10 mm. The risk of metachronous neoplasia, including adenomas and SSLs, was compared in individuals with a normal index colonoscopy and those with <10-mm HPs stratified by location and number of HPs. RESULTS After exclusion, 1795 patients were included. At index colonoscopy, 82% (n = 1469) had a normal examination, 12% (219) had only 1, and 6% (107) had between 2 and 9 HPs <10 mm. Compared with patients with a normal index colonoscopy, patients with a proximal (odds ratio, 3.82; 95% confidence interval, 1.77-7.53) or distal HP (odds ratio, 2.23; 95% confidence interval, 1.18-4.00) had an increased risk of metachronous SSLs but not adenomas. CONCLUSIONS Patients with small proximal and distal HPs are at increased risk of metachronous SSLs. These preliminary findings warrant consideration during surveillance recommendations and future studies in larger cohorts.

Long-Term Outcomes of Pancreas-Sparing Duodenectomy for Duodenal Polyposis in Familial Adenomatous Polyposis Syndrome. J Gastrointest Surg 2021; 25:1233-1240. [PMID: 32410179 DOI: 10.1007/s11605-020-04621-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/04/2020] [Accepted: 04/19/2020] [Indexed: 01/31/2023]
Abstract
BACKGROUND Pancreas-sparing duodenectomy (PSD) offers definitive therapy for duodenal polyposis associated with familial adenomatous polyposis (FAP). We reviewed the long-term complications of PSD and evaluated the incidence of high-grade dysplasia (HGD) and cancer in the remaining upper gastrointestinal tract. METHODS Forty-seven FAP patients with duodenal polyposis undergoing PSD from 1992 to 2019 were reviewed. Long-term was defined as > 30 days from PSD. RESULTS All patients were treated with an open technique, and 43 (91.5%) had Spigelman stage III or IV duodenal polyposis. Median follow-up was 107 months (IQR, 26-147). There was no 90-day mortality. Seven patients died at a median of 10.5 years (IQR, 5.4-13.3) after PSD, with one attributed to gastric cancer. Pancreatitis occurred in 10 patients (21.3%), and two required surgical intervention. Seven patients (14.9%) developed an incisional hernia, and all underwent definitive repair. Forty-one patients (87.2%) had postoperative surveillance endoscopy over a median follow-up of 111 months (IQR, 42-138). Three patients (6.4%) developed adenocarcinoma (two gastric, one jejunal), and four (8.5%) had adenomas with HGD (two gastric, two jejunal) with a median of 15 years (IQR, 9-16) from PSD. One patient with gastric adenocarcinoma and all patients with HGD or adenocarcinoma of the jejunum required surgical intervention. CONCLUSION PSD can be performed with a low but definable risk of long-term morbidity. Risk of gastric and jejunal carcinoma rarely occurs and was diagnosed decades after PSD. This demonstrates the need for lifelong endoscopic surveillance and educates us on the risk of carcinoma in the remaining gastrointestinal tract.

Malignancy risk in individuals with familial adenomatous polyposis receiving biologics and immunomodulators. Fam Cancer 2021; 21:189-195. [PMID: 33822277 DOI: 10.1007/s10689-021-00250-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2020] [Accepted: 03/29/2021] [Indexed: 12/19/2022]
Abstract
Clinicians may be hesitant to prescribe biologics or immunomodulators to individuals with familial adenomatous polyposis (FAP) and comorbid inflammatory disease (CID) because of increased cancer risk. Our aim was to compare the risk of malignancy in FAP individuals with inflammatory bowel (IBD) and/or rheumatic disease that received biologics/immunomodulators to those who did not. Individuals with FAP and CID were included in the study. We compared the incidence of cancer between individuals exposed to biologics/immunomodulators compared to unexposed from the date of diagnosis of comorbid disease till last follow up or death. Hazard ratio (HR) for cancer was computed using Cox regression model and compared by exposure status to biologic/immunomodulators. 25 individuals with FAP and a comorbid inflammatory disease were identified including 9 (36%) with IBD and 16 (64%) with rheumatic disease. 14 (56%) were exposed to a biologic and or immunomodulator. Median duration of biologic/immunomodulator exposure was 48 (2-180) months. 3 (21.4%) in the exposed group compared to 1 (9.1%) in the unexposed group developed cancer with a HR for exposure of 1.92 (CI 0.2-18.5, p = 0.57). Median duration of follow up after the diagnosis of inflammatory disease was 10 (5.5-17.0) years in the exposed and 6 (3.0-15.0) years in the unexposed group. In the exposed group, 1 patient developed gastric and 2 developed colon cancer. One unexposed patient developed medullary thyroid cancer. There is a possible trend of more cancers in the group that received biologics/immunomodulators-but given the small number of patients and p-value, there may be no difference at all. This preliminary finding warrants study in a larger cohort.

Risks, Benefits, and Effects on Management for Biopsy of the Papilla in Patients With Familial Adenomatous Polyposis. Clin Gastroenterol Hepatol 2021; 19:760-767. [PMID: 32492482 DOI: 10.1016/j.cgh.2020.05.054] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/15/2020] [Revised: 05/20/2020] [Accepted: 05/27/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Ampullary and duodenal cancer are the leading causes of death in patients with familial adenomatous polyposis (FAP) after colectomy has been performed. Risk of duodenal cancer is determined based on Spigelman stage (SS) of duodenal polyposis. Guidelines recommend endoscopic surveillance of the duodenum and visualization of the papilla to stage duodenal polyposis. There is no consensus on whether biopsies should be routinely collected from duodenal papilla and findings included in SS. Additionally, there are no data on the risk of pancreatitis after biopsy collection from papilla of patients with FAP. We studied the incidence of pancreatitis after biopsy of the papilla in patients with FAP and effects of biopsy findings on SS. METHODS We identified consecutive patients with FAP at a single center from January 2011 through December 2018 with ≥1 endoscopy with biopsy of the papilla. Patients with history of foregut surgery were excluded. We identified 273 patients with FAP who had biopsies collected from papilla over 792 EGDs, with 1-8 independent exams with biopsy per patient. We collected demographic, endoscopic, and histology data from patients and calculated SS with vs without biopsy findings. Post-procedural pancreatitis was defined by 2 of the following: abdominal pain, lipase level 3-fold the upper limit of normal, or radiography findings consistent with pancreatitis within 7 days of esophagogastroduodenoscopy (EGD). RESULTS Pancreatitis developed in 2 patients (0.73%): 1 after biopsy of a normal-appearing papilla and 1 after biopsy of an abnormal appearing papilla. Inclusions of biopsy data increased SS in 36 patients (13.2%), with consideration of prophylactic duodenectomy for 3.3%. CONCLUSIONS Pancreatitis after biopsy of the duodenal papilla is rare. Histology data obtained from biopsy of the papilla in patients with FAP can change SS and affect patient management.

Chemoprevention in familial adenomatous polyposis: past, present and future. Fam Cancer 2021; 20:23-33. [PMID: 32507936 PMCID: PMC7276278 DOI: 10.1007/s10689-020-00189-y] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2020] [Accepted: 05/18/2020] [Indexed: 01/05/2023]
Abstract
Familial adenomatous polyposis (FAP) is a hereditary colorectal cancer syndrome characterized by colorectal adenomas and a near 100% lifetime risk of colorectal cancer (CRC). Prophylactic colectomy, usually by age 40, is the gold-standard therapy to mitigate this risk. However, colectomy is associated with morbidity and fails to prevent extra-colonic disease manifestations, including gastric polyposis, duodenal polyposis and cancer, thyroid cancer, and desmoid disease. Substantial research has investigated chemoprevention medications in an aim to prevent disease progression, postponing the need for colectomy and temporizing the development of extracolonic disease. An ideal chemoprevention agent should have a biologically plausible mechanism of action, be safe and easily tolerated over a prolonged treatment period, and produce a durable and clinically meaningful effect. To date, no chemoprevention agent tested has fulfilled these criteria. New agents targeting novel pathways in FAP are needed. Substantial preclinical literature exists linking the molecular target of rapamycin (mTOR) pathway to FAP. A single case report of rapamycin, an mTOR inhibitor, used as chemoprevention in FAP patients exists, but no formal clinical studies have been conducted. Here, we review the prior literature on chemoprevention in FAP, discuss the rationale for rapamycin in FAP, and outline a proposed clinical trial testing rapamycin as a chemoprevention agent in patients with FAP.
