Background and Objectives In contrast with sporadic colorectal cancer liver metastases (CRLM), inflammatory bowel disease (IBD)‐related CRLM have not been studied to date. Methods Patients who underwent resection for IBD‐related and sporadic CRLM from 2000 to 2015 were identified from an international registry and matched for pertinent prognostic variables. Overall survival (OS) and recurrence‐free survival (RFS) were subsequently assessed. Results Twenty‐eight patients had IBD‐related CRLM. Synchronous extrahepatic disease was more common in IBD‐related CRLM patients than patients with sporadic CRLM (28.6% vs 8.3%; P < 0.001), most commonly located in the lungs. In multivariable analysis, IBD did not have a significant influence on OS ( P = 0.835), and had a hazard ratio (HR) close to 1 (HR, 0.95; 95% confidence interval [CI], 0.57‐1.57). IBD was also not associated with inferior RFS (HR, 1.07; 95%CI, 0.68‐1.68; P = 0.780). Among patients with IBD‐related CRLM, 9(50%) had isolated intrahepatic recurrence and 8(44.4%) isolated extrahepatic recurrence, while only 1(5.6%) developed combined recurrence. Of those who experienced recurrence after resection of IBD‐related CRLM, 10 had their recurrence treated with curative intent. Conclusions Patients with IBD‐related CRLM had similar survival compared with patients with sporadic CRLM, even though they more often present with extrahepatic disease. In addition, patients with IBD‐related CRLM may experience patterns of recurrence different from patients with sporadic CRLM.
