Abstract Background In a 6-year, multicenter, prospective nested case–control study, we aimed to evaluate risk factors for incident cancer in inflammatory bowel disease (IBD), when considering clinical characteristics of IBD and immunomodulator use. The secondary end point was to provide characterization of incident cancer types. Methods All incident cases of cancer occurring in IBD patients from December 2011–2017 were prospectively recorded in 16 Italian Group for the Study of Inflammatory Bowel Disease units. Each of the IBD patients with a new diagnosis of cancer was matched with 2 IBD patients without cancer, according to IBD phenotype (ulcerative colitis [UC] vs Crohn’s disease [CD]), age (±5 years), sex. Risk factors were assessed by multivariate logistic regression analysis. Results Cancer occurred in 403 IBD patients: 204 CD (CD cases), 199 UC (UC cases). The study population included 1209 patients (403 IBD cases, 806 IBD controls). Cancer (n = 403) more frequently involved the digestive system (DS; 32%), followed by skin (14.9%), urinary tract (9.7%), lung (6.9%), genital tract (6.5%), breast (5.5%), thyroid (1.9%), lymphoma (2.7%, only in CD), adenocarcinoma of the small bowel (SBA; 3.9%, 15 CD, 1 pouch in UC), other cancers (15.9%). Among cancers of the DS, colorectal cancer (CRC) more frequently occurred in UC (29% vs 17%; P < 0.005), whereas SBA more frequently occurred in CD (13% vs 6.3% P = 0.039). In CD, perforating (B3) vs non-stricturing non-perforating (B1) behavior represented the only risk factor for any cancer (odds ratio [OR], 2.33; 95% confidence interval [CI], 1.33–4.11). In CD, risk factors for extracolonic cancer (ECC) were a B3 vs B1 and a stricturing (B2) vs B1 behavior (OR, 2.95; 95% CI, 1.62–5.43; OR, 1.79; 95% CI, 1.09–2.98). In UC, risk factors for ECC and for overall cancer were abdominal surgery for UC (OR, 4.63; 95% CI, 2.62–8.42; OR, 3.34; 95% CI, 1.88–5.92) and extensive vs distal UC (OR, 1.73; 95% CI, 1.10–2.75; OR, 1.99; 95% CI, 1.16–3.47). Another risk factor for ECC was left-sided vs distal UC (OR, 1.68; 95% CI, 1.00–2.86). Inflammatory bowel disease duration was a risk factor for skin and urinary tract cancers. Conclusions Perforating CD, extensive UC, and abdominal surgery for UC were identified as risk factors for overall incident cancer and for ECC. The clinical characteristics associated with severe IBD may increase cancer risk.

IntroductionThe epidemiology of inflammatory bowel disease (IBD) in sub-Saharan Africa is poorly documented. We have started a registry to determine the burden, phenotype, risk factors, disease course and outcomes of IBD in Zimbabwe.Methods and analysisA prospective observational registry with a nested case–control study has been established at a tertiary hospital in Harare, Zimbabwe. The registry is recruiting confirmed IBD cases from the hospital, and other facilities throughout Zimbabwe. Demographic and clinical data are obtained at baseline, 6 months and annually. Two age and sex-matched non-IBD controls per case are recruited—a sibling or second-degree relative, and a randomly selected individual from the same neighbourhood. Cases and controls are interviewed for potential risk factors of IBD, and dietary intake using a food frequency questionnaire. Stool is collected for 16S rRNA-based microbiota profiling, and along with germline DNA from peripheral blood, is being biobanked. The estimated sample size is 86 cases and 172 controls, and the overall registry is anticipated to run for at least 5 years. Descriptive statistics will be used to describe the demographic and phenotypic characteristics of IBD, and incidence and prevalence will be estimated for Harare. Risk factors for IBD will be analysed using conditional logistic regression. For microbial analysis, alpha diversity and beta diversity will be compared between cases and controls, and between IBD phenotypes. Mann-Whitney U tests for alpha diversity and Adonis (Permutational Multivariate Analysis of Variance) for beta diversity will be computed.Ethics and disseminationEthical approval has been obtained from the Parirenyatwa Hospital’s and University of Zimbabwe’s research ethics committee and the Medical Research Council of Zimbabwe. Findings will be discussed with patients, and the Zimbabwean Ministry of Health. Results will be presented at scientific meetings, published in peer reviewed journals, and on social media.Trial registration numberNCT04178408.

The Impact

The role of early-life environmental exposures on Inflammatory Bowel Disease (IBD) onset remains unclear. We aimed to quantify the impact of perinatal conditions and antibiotic use in the first 6 and 12 months of life, on the risk of childhood-onset IBD, in a birth cohort of the region Friuli-Venezia Giulia (Italy). A nested case-control design on a longitudinal cohort of 213,515 newborns was adopted. Conditional binomial regression models were used to estimate Odds Ratios (OR) with 95% confidence intervals (CI) for all analyzed risk factors. We identified 164 individuals with IBD onset before the age of 18 years and 1640 controls. None of the considered perinatal conditions were associated with IBD. Analyses on antibiotic exposure were based on 70 cases and 700 controls. Risks were significantly higher for children with ≥4 antibiotic prescriptions in the first 6 and 12 months of life (OR = 6.34; 95%CI 1.68–24.02 and OR = 2.91; 95%CI 1.31–6.45, respectively). This association was present only among patients with Crohn’s disease and those with earlier IBD onset. We found that perinatal characteristics were not associated to IBD, while the frequent use of antibiotics during the first year of life was associated to an increased risk of developing subsequent childhood-onset IBD.

Abstract Background Inflammatory bowel disease (IBD) patients are at increased risk for developing extra-intestinal malignancies, mainly due to immunosuppressive medication. The risk of developing head and neck cancer in immunosuppressed transplant patients is increased. The relation between IBD patients and laryngeal cancer (LC) remains unclear. We aimed (1) to identify risk factors in IBD patients for LC development and (2) to compare clinical characteristics, outcome, and survival of LC in IBD patients with the general population. Methods All IBD patients with LC (1993–2011) were retrospectively identified using the Dutch Pathology Database. We performed 2 case–control studies: (1) to identify risk factors, we compared patients with IBD and LC (cases) with the general IBD population; (2) to analyze LC survival, we compared cases with controls from the general LC population. Results We included 55 cases, 1800 IBD controls, and 2018 LC controls. Cases were more frequently male compared with IBD controls (P &lt; 0.001). For ulcerative colitis (UC), cases were older at IBD diagnosis (P &lt; 0.001). Crohn’s disease (CD) cases were more frequently tobacco users (P &lt; 0.001) and more often had stricturing (P = 0.006) and penetrating (P = 0.008) disease. We found no survival difference. Immunosuppressive medication had no impact on survival. Conclusions Male sex was a risk factor for LC in IBD patients. Older age at IBD diagnosis was a risk factor for UC to develop LC. Tobacco use and stricturing and penetrating disease were risk factors for LC development in CD patients. Inflammatory bowel disease was not associated with impaired survival of LC. Immunosuppressive medication had no influence on survival.
