Background and aims: The widespread use of anti-tumour necrosis factor α antibody (Infliximab) in Crohn’s disease (CD) raises concerns about a possible cancer risk in the long term. In a matched pair study, we assessed whether Infliximab is associated with an increased risk of neoplasia. Methods: In a multicentre matched pair study, 404 CD patients treated with Infliximab (CD-IFX) were matched with 404 CD patients who had never received Infliximab (CD-C). Cases and controls were matched for sex, age (±5 years), site of CD, age at diagnosis (±5 years), immunosuppressant use, and follow up. New diagnoses of neoplasia from April 1999 to October 2004 were recorded. Results: Among the 404 CD-IFX, neoplasia was diagnosed in nine patients (2.22%) while among the 404 CD-C, seven patients developed neoplasia (1.73%) (odds ratio 1.33 (95% confidence interval 0.46–3.84); p = 0.40). The survival curve adjusted for patient year of follow up showed no differences between CD-IFX and CD-C (p = 0.90; log rank test). In the CD-IFX group, there was one cholangiocarcinoma, three breast cancers, one skin cancer, one leukaemia, one laryngeal cancer, and two anal carcinomas. Among the 7/404 (1.73%) CD-C, there were three intestinal adenocarcinomas (two caecum, one rectum), one basalioma, one spinalioma, one non-Hodgkin’s lymphoma, and one breast cancer. Age at diagnosis of neoplasia did not differ between groups (CD-IFX v CD-C: median 50 (range 40–70 years) v 45 (27–72); p = 0.50). Conclusion: In our multicentre matched pair study, the frequency of a new diagnosis of neoplasia in CD patients treated with Infliximab was comparable with CD patients who had never received Infliximab.

Summary: Background: Infliximab and adalimumab are highly effective in Crohn's Disease (CD). This is supported by clinical trials and open‐label studies using either infliximab or adalimumab, thus not allowing a proper comparison between these anti‐TNFs in CD.Aim: To evaluate the efficacy and safety of infliximab and adalimumab in active CD.Methods: In a longitudinal study, CD patients with indication for anti‐TNFs were treated with infliximab or adalimumab.Results: Ninety‐three patients were treated with infliximab (n = 44) or adalimumab (n = 49). In the infliximab group, the induction was completed by 77.3% of patients, due to no response (n = 2), delayed hypersensitivity reactions (DHR) or infusion reactions (n = 8). Maintenance with infliximab was completed by 60% of patients, due to clinical worsening or loss of efficacy (n = 5), DHR or infusion reactions (n = 5). In the adalimumab group, all patients completed the induction, while maintenance was completed by 67% of patients, due to clinical worsening or loss of efficacy (n = 8), DHR (n = 1), other causes (n = 7). In both groups, the CDAI significantly reduced at baseline vs. each visit (P < 0.04). The Kaplan–Meier survival analysis performed to evaluate the risk of steroid‐free remission in patients treated with infliximab vs. adalimumab detected no differences (log‐rank test P = 0.4). Cox proportional‐hazards regression identified two predictors of steroid‐free remission using anti‐TNFs: no smokers [HR = 2.94 (1.52–5.70), P = 0.001] and non stricturing non penetrating behaviour [HR = 3.116 (1.06–9.13), P = 0.03826].Conclusions: Infliximab and adalimumab showed a similar efficacy. No smoking and non‐stricturing non‐penetrating behaviour were predictors of steroid‐free remission.
