ABSTRACT
Objective:
To analyze the clinical characteristics of patients with inflammatory bowel disease (IBD) complicated with intra- and extra-intestinal tumors, and so as to provide reference for clinical practice.Methods:
From October 2008 to March 2022, the clinical data of 2 360 IBD patients diagnosed at the First Affiliated Hospital of Air Force Military Medical University were collected, and the IBD patients complicated with intra- and extra-intestinal tumors were screened out. IBD with colorectal cancer, small intestine cancer and intestinal lymphoma were enrolled into intra-intestinal tumor group, IBD complicated with other tumors except intra-intestinal tumors were enrolled into extra-intestinal tumor group. The clinical characteristics of the 2 groups were retrospectively compared, and the risk factors affecting survival of IBD complicated intra- and extra-intestinal tumor were analyzed. Kaplan-Meier method was used to draw the survival curve, Cox regression model was performed to analyze the prognostic risk factors, and independent sample t test, Fisher′s exact test and log-rank test were used for statistical analysis.Results:
A total of 43 IBD patients with intra- and extra-intestinal tumor were screened out, and the overall tumor incidence rate was 1.82% (43/2 360). The rate of IBD complicated with intra-intestinal tumor accounted for 1.27% (30/2 360). Among them, the rate of ulcerative colitis (UC) complicated with intra-intestinal tumor was 1.48% (25/1 685), and the rate of Crohn′s disease (CD) complicated with intra-intestinal tumor was 0.74% (5/675). The rate of IBD with extra-intestinal tumor accounted for 0.55% (13/2 360). Among them, the rate of UC complicated with extra-intestinal tumor was 0.71% (12/1 685), and the rate of CD complicated with extra-intestinal tumor was 0.15% (1/675). There were no significant differences in the rate of intra- and extra-intestinal tumors between UC and CD patients (both P>0.05). In the intra-intestinal tumor group, the age when diagnosed with IBD and the age when tumor diagnosed were (37.0±13.8) years old and (47.7±13.5) years old, which were both lower than those of the extra-intestinal tumor group ((51.8±6.2) years old and (60.7±7.8) years old), and the differences were statistically significant ( t=-3.69 and -3.24, P=0.001 and 0.002). The lesion location when tumor diagnosed of UC patients with intra-intestinal tumor mainly was extensive colonic type(64.0%, 16/25), followed by left part colonic type and rectal type in turn (28.0%, 7/25 and 8.0%, 2/25). In UC patients with extra-intestinal tumor, mainly was rectal type (8/12), followed by left part colonic type (3/12) and extensive colonic type (1/12) in turn. There was statistically significant difference bwtween the UC patients with intra- and extra-intestinal tumor in the extent of lesions when tumor diaghosed (Fisher′s exact test, P<0.001). The activity of IBD of intra-intestinal tumor group when tumor diagnosed mainly was severe activity phase (46.7%, 14/30), followed by moderate activity phase, mild activity phase and remission phase in turn (33.3%, 10/30; 20.0%, 6/30 and 0). The activity of IBD of extra-intestinal tumor group when tumor diagnosed mainly was remission phase (7/13), followed by moderate activity phase, mild activity phase and severe activity phase in turn (3/13, 2/13 and 1/13). There were statistically significant differences between the 2 groups in the composition of IBD activity when tumor diagnosed (Fisher′s exact test, P<0.001). The survival analysis indicated the median survival time of IBD complicated with intra-intestinal tumor group was 145.9 months, and that of the extra-intestinal tumor group was 29.9 months. The results of multivariate Cox analysis showed that the occurrence of extra-intestinal tumor was an independent risk factor of patient survival rate( HR=5.119, 95% confidence interval 1.485 to 17.643, P=0.010).Conclusions:
IBD patients had a high risk of developing intra- and extra-intestinal tumors. The intra-intestinal tumor group mainly is extensive colonic type and severe active period, while the extra-intestinal tumor group mainly is rectal type and remission period. Compared with that of the extra-intestinal tumor group, the age at time of IBD onset and tumor diagnosed of intestinal tumor are younger, and the survival time is longer.
