Serrated polyposis syndrome (SPS) implies a slightly elevated risk of colorectal cancer (CRC) during endoscopic follow-up, but its natural course is still not well known. The main objective of this study was to describe the long-term risk of developing advanced neoplasia (AN) in these patients. Until October 2020, individuals who fulfilled 2010 WHO criteria I and/or III for SPS were retrospectively recruited. We selected those under endoscopic surveillance after resection of all lesions >3 mm in a high-quality colonoscopy. We excluded patients with total colectomy at diagnosis and those with any interval between colonoscopies >3.5 years. We defined AN as advanced serrated polyp (≥10 mm and/or with dysplasia), advanced adenoma, or CRC. In 109 patients, 342 colonoscopies were performed (median = 3, median interval = 1.8 years) during a median follow-up after colonic clearance of 5.0 years. Five-year cumulative incidences of AN were 21.6% globally, and 5.6%, 10.8%, and 50.8% in patients who fulfilled criterion I, III, and both, respectively (p < 0.001). No CRC was diagnosed and only 1 (0.9%) patient underwent surgery. In conclusion, cumulative incidences of AN could be lower than previously described, at least in patients who fulfil the 2010 WHO criterion III alone. Therefore, low-risk individuals might benefit from less stringent surveillance.

Abstract Background and aims The family of serrated polyps (SP) includes hyperplastic polyps (HP), sessile serrated adenomas/polyps, and traditional serrated adenoma. We investigated whether SP synchronous with adenoma at index colonoscopy is associated with metachronous advanced colorectal neoplasia (CRN). Methods Patients with ≥ 1 adenoma on index colonoscopy and who had undergone a follow-up colonoscopy were included. The patients were divided into four groups according to the presence of SP and advanced adenoma (AA) on index colonoscopy (non-AA, non-AA + SP, AA, AA + SP). The cumulative incidence of metachronous advanced CRN at surveillance colonoscopy was compared between groups. Results Among a total of 2209 patients, the numbers of patients in the non-AA, non-AA + SP, AA, and AA + SP groups were 922, 441, 625, and 221, respectively. The cumulative incidence of metachronous advanced CRN was higher in patients in the AA + SP group than that in the AA group (P<0.001), and there was no significant difference between the non-AA + SP group and the non-AA group (P = 0.06). The cumulative incidence of metachronous advanced CRN at 3 years was 17.9 % [95 % confidence interval (CI) 8.0–27.6], 10.7 % [95 %CI 7.7–3.6], 3.5 % [95 %CI 1.3–5.6], and 3.4 % [95 %CI 2.0–4.7] in the AA + SP, AA, non-AA + SP, and non-AA group, respectively. In a multivariate analysis, overall SP [hazard ratio (HR) 2.24; 95 %CI 1.38–3.64, P = 0.001], proximal SP (HR 2.31; 95 %CI 1.32–4.08), and HP (HR 2.19; 95 %CI 1.35–3.57) were risk factors for metachronous advanced CRN in patients with AA on index colonoscopy. Conclusions Coexistent AA and SP on index colonoscopy significantly increased the risk of metachronous advanced CRN compared with AA alone. Further large prospective studies are needed to confirm whether more intensive follow-up improves outcomes in these high risk patients.

Background: During unifocalization procedures for pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries, collateral arteries are either ligated or detached. Not much is known of the fate of the remaining arterial origins in the long term. Available computed tomography (CT) or magnetic resonance (MR) imaging of the intrathoracic arteries was examined to investigate possible abnormalities at the former position of the collateral arteries as well as ascending aortic diameters. Methods: From 1989 to 2018, we performed 66 unifocalization procedures in 39 patients. One hundred and twenty-nine collateral arteries were ligated or detached. In 52% (15) of the surviving patients (with a total of 55 ligated or detached collaterals), sufficient imaging of the thoracic aorta from CT (11) and/or MR (9) was available for evaluation. Results: The median interval between unifocalization procedure and imaging was 15 years (interquartile range [IQR]: 9-19 years). In 93% (14) of the scanned patients, 18 blunt ends were detected at the location of a former collateral artery. No aneurysm formation of the descending aorta was observed. The median diameter of the ascending aorta was 35 mm (IQR: 31-40 mm). During follow-up, no aortic dissection or rupture occurred. Conclusions: Aortic imaging late after unifocalization showed abnormalities in 93% of the scanned patients. Abnormalities consisted mostly of blunt ends of the former collateral artery. We recommend to include routine imaging of the aorta during late follow-up to detect eventual future abnormalities and monitor aortic diameters. Ascending aortic diameters showed slight dilatation with no clinical implications so far.

ObjectivesSurveillance colonoscopy is thought to prevent colorectal cancer (CRC) in patients with long-standing colonic IBD, but data regarding the frequency of surveillance and the findings thereof are lacking. Our aim was to determine whether consecutive negative surveillance colonoscopies adequately predict low neoplastic risk.DesignA multicentre, multinational database of patients with long-standing IBD colitis without high-risk features and undergoing regular CRC surveillance was constructed. A ‘negative’ surveillance colonoscopy was predefined as a technically adequate procedure having no postinflammatory polyps, no strictures, no endoscopic disease activity and no evidence of neoplasia; a ‘positive’ colonoscopy was a technically adequate procedure that included at least one of these criteria. The primary endpoint was advanced colorectal neoplasia (aCRN), defined as high-grade dysplasia or CRC.ResultsOf 775 patients with long-standing IBD colitis, 44% (n=340) had >1 negative colonoscopy. Patients with consecutive negative surveillance colonoscopies were compared with those who had at least one positive colonoscopy. Both groups had similar demographics, disease-related characteristics, number of surveillance colonoscopies and time intervals between colonoscopies. No aCRN occurred in those with consecutive negative surveillance, compared with an incidence rate of 0.29 to 0.76/100 patient-years (P=0.02) in those having >1 positive colonoscopy on follow-up of 6.1 (P25–P75: 4.6–8.2) years after the index procedure.ConclusionWithin this large surveillance cohort of patients with colonic IBD and no additional high-risk features, having two consecutive negative colonoscopies predicted a very low risk of aCRN occurrence on follow-up. Our findings suggest that longer surveillance intervals in this selected population may be safe.

9551 Background: Ifosfamide-induced nephrotoxicity is a significant issue in patients treated for tumours during childhood. This study aimed at documenting incidence of late renal toxicity of ifosfamide and its risk factors. Methods: 183 patients have been investigated. 100 were male. Median age at treatment was 9.3 years (0.4–18 years). Median dose of ifosfamide was 54 g/m2 (18–77 g/m2). No patients received cisplatin and/or carboplatinum. Diagnoses included rhabdomyosarcoma (77), other soft tissue sarcoma (39), Ewing (39), and osteosarcoma (28). Investigations were performed at a median interval of 10.3 years (5–20.7) after the end of the treatment, at a median age of 21.6 years (7.1–44.2). No patient had electrolyte or vitamine supplementation. Glomerular and tubular functions were graded according to the Skinner's system. Results: After 5 year minimal follow-up 55% had normal tubular and 79% had normal glomerular functions. Natraemia, kalaemia, serum HCO3 and calcaemia were normal in all patients. Hypomagnesaemia was observed in 4, hypophosphaetemia in 8 %. The tubular threshold for phosphate was reduced in 44% of the patients (grade 2 or 3 in 15%, grade 3 in 1 pt). Significant glycosuria (> 0.5 g/24h) was detected in 5 % of the patients but it was clearly abnormal only in 5 patients. 34% of the patients had beta2 microglobulinuria, however, proteinuria was observed in only 12%. Cumulative dose of ifosfamide, older age at treatment and follow-up since treatment were predictor for tubulopathy in univariate and multivariate analyse. The glomerular filtration rate was normal in 79% of the patients. 21% had a grade 1 toxicity and 1 patient a grade 2. Univariate analysis did not find any prognostic factor for glomerular toxicity apart from the association with tubular toxicity. Conclusions: Since ifosfamide-induced renal toxicity can be severe, long term evaluation is important and this risk should be balanced carefully against efficacy. No significant financial relationships to disclose.

Risk Of Malignancy

AbstractPrevious research has confirmed that patients with choledochal cyst have an elevated risk of cholangiocarcinoma and gallbladder carcinoma. Current data suggest a risk of malignancy of 6 to 30% in adults with choledochal cyst. Malignancy has also occasionally been identified in children and adolescents. Multiple factors, including the age of the patient, cyst type, histological findings, and localization, have an impact on the prognosis. Information on long-term outcomes after cyst excision is limited. However, recent data suggest a lifelong elevated risk of up to 4% of cancer development following operation. This paper presents a review of the literature on cancer in patients with choledochal cyst before and after excision. A postoperative follow-up concept that consists of annual controls of CA19–9 and abdominal ultrasound is introduced.
