Abstract Background Inflammatory bowel disease [IBD] is a risk factor for colorectal cancer [CRC]. The aim of this study is to determine whether stage at diagnosis and survival differ between sporadic, ulcerative colitis [UC]- and Crohn’s disease [CD]-related CRC. Methods The English National Cancer Registry [NCIN], Hospital Episode Statistics [HES] and Office for National Statistics [ONS] datasets between 2000 and 2010 were linked, providing data on comorbidities, stage and date of death. A logistic regression model determined whether IBD was associated with an early [I/II] or late [III/IV] cancer. Cox regression analysis was used to examine survival differences between sporadic, UC- and CD-related cancers. Results A total of 234 009 patients with CRC were included, of whom 985 [0.4%] and 1922 [0.8%] had CD and UC, respectively. UC, but not CD, was associated with an earlier stage compared with sporadic cancers (odds ratio [OR] 0.88, 95% confidence interval [CI] 0.79 to 0.98, p = 0.02). CD had a significantly worse survival compared with sporadic patients for stage II [HR = 1.71, CI 1.26 to 2.31 p <0.005] and III [1.53, CI 1.20 to 1.96, p <0.005] cancer. UC patients were associated with worse survival compared with the sporadic group for both stage III [1.38, CI 1.17 to 1.63, p <0.0005] and IV [1.13, CI 1.01 to 1.28, p = 0.04] cancer. After excluding sporadic patients, UC was associated with improved survival compared with CD [0.62, CI 0.43 to 0.90, p = 0.01] for stage II cancer. Conclusions Patients with IBD are diagnosed at an earlier stage but tend to have a worse survival compared with sporadic cases of CRC, in particular for nodal disease [stage III].Specifically, patients with CD-related CRC appear to fare worst in terms of survival compared with both the sporadic and UC groups.

BackgroundPatients with inflammatory bowel disease (IBD) have increased risk of developing colorectal cancer (CRC), depending on the duration and severity of the disease. The evolutionary process in IBD is driven by chronic inflammation leading to epithelial-to-mesenchymal transition (EMT) events in colonic fibrotic areas. EMT plays a determinant role in tumor formation and progression, through the acquisition of ‘stemness’ properties and the generation of neoplastic cells. The aim of this study is to monitor EMT/cancer initiating tracts in IBD in association with the deep characterization of inflammation in order to assess the mechanisms of IBD severity and progression towards malignancy.Methods10 pediatric and 20 adult IBD patients, admitted at Sidra Medicine (SM) and Hamad Medical Corporation (HMC) respectively, have been enrolled in this study, from whom gut tissue biopsies (from both left and right side) were collected. Retrospectively collected tissues (N=10) from patients with malignancy and history of IBD were included in the study. DNA and RNA were extracted from fresh small size (2–4 mm in diameter) gut tissues using the BioMasher II (Kimble) and All Prep DNA/RNA kits (Qiagen). MicroRNA (miRNA; N=700) and gene expression (N=800) profiling have been performed (cCounter platform; Nanostring) as well as the methylation profiling microarray (Infinium Methylation Epic Bead Chip kit, Illumina) to interrogate up to 850,000 methylation sites across the genome.ResultsDifferential miRNA profile (N=27 miRNA; p<0.05) was found by the comparison of tissues from pediatric and adult patients. These miRNAs regulate: i. oxidative stress damage (e.g., miR 99b), ii. hypoxia induced autophagy; iii. genes associated with the susceptibility to IBD (ATG16L1, NOD2, IRGM), iv. immune responses, such as TH17 T cell subset (miR 29). N=6 miRNAs (miR135b, 10a196b, 125b, let7c, 375) linked with the regulation of Wnt/b-catenin, EM-transaction, autophagy, oxidative stress and play role also in cell proliferation and mobilization and colorectal cancer development were differentially expressed (p<0.05) in tissues from left and right sides of gut. Gene expression signature, including genes associated with inflammation, stemness and fibrosis, has also been performed for the IBD tissues mentioned above. Methylation sites at single nucleotide resolution have been analyzed.ConclusionsAlthough the results warrant further investigation, differential genomic profiling suggestive of altered pathways involved in oxidative stress, EMT, and of the possible stemness signature was found. The integration of data from multiple platforms will provide insights of the overall molecular determinants in IBD patients along with the evolution of the disease.Ethics ApprovalThis study was approved by Sidra Medicine and Hamad Medical Corporation Ethics Boards; approval number 180402817 and MRC-02-18-096, respectively.

Background: Anti-tumor necrosis factor (TNF) agents are increasingly used for rheumatic diseases and inflammatory bowel disease (IBD), but are associated with the development of anti-TNF-induced lupus (ATIL). Nonetheless, few ATIL studies on non-Caucasian IBD patients exist. Here, we investigated the incidence, clinical features, and risk factors of ATIL in Korea. Methods: We retrospectively reviewed the medical records of IBD patients undergoing anti-TNF therapy at our tertiary IBD center between 2008 and 2020. ATIL was diagnosed as a temporal association between symptoms and anti-TNF agents, and the presence of at least one serologic and non-serologic American College of Rheumatology criterion. The risk factors for ATIL occurrence were assessed using multivariate Cox regression analysis. Results: Of 1362 IBD patients treated with anti-TNF agents, 50 (3.7%) ATIL cases were suspected, of which 14 (1.0%) received a definitive diagnosis. Arthritis and mucocutaneous symptoms were observed in 13 and 4 patients, respectively. All ATIL cases were positive for anti-nuclear and anti-dsDNA antibodies. Four patients (30.8%) improved while continuing anti-TNF therapy. At the final follow up, the ATIL group ( n = 14) had a lower IBD remission rate (30.8% versus 68.8%, p = 0.019) than the non-ATIL group ( n = 36). Ulcerative colitis and longer disease duration were associated with ATIL occurrence, with hazard ratios of 7.017 ( p = 0.005) and 1.118 ( p = 0.002), respectively. Conclusion: Although rare, ATIL is associated with poor treatment response to IBD in Korean patients. ATIL should be considered if arthritis and mucocutaneous symptoms develop during anti-TNF therapy for IBD.
