BACKGROUND: Inflammatory bowel diseases (IBDs) pose an increased risk of gastrointestinal cancer with especially worse prognosis. Cytoreductive surgery and heated intraperitoneal chemotherapy (CRS/HIPEC) improves outcomes in selected patients with colorectal peritoneal metastases. Little published data describes the outcomes of CRS/HIPEC in IBD patients.
METHODS: We performed a retrospective review of a prospectively maintained CRS/HIPEC database. Outcomes in patients with and without IBD were compared for short-term outcomes such as hospital/intensive care unit stay, blood loss/transfusions, complications, and reoperations. We also examined oncological outcomes including recurrence, overall (OS), and disease-free survival (DFS).
RESULTS: We identified 232 patients that underwent CRS/HIPEC for colorectal or small bowel adenocarcinoma, of which 10 were with IBD. Patients with IBD had lower ASA (p=0.005), less hypertension (p=0.033), and 30% small bowel primary compared to none in the non-IBD cohort (p<0.001). Otherwise, demographic and perioperative characteristics were similar between the groups. The median peritoneal cancer index (PCI) was 7 and similar between the cohorts (p=0.422). Extent of organ resections and peritonectomies performed were similar. Complications occurred in 60.3% of patients (21.2% major), similar between the groups (p=0.744 and p=0.444, respectively). Reoperation rate of 27% was similar between groups (p=0.097). The median OS in the IBD cohort was 19.6 vs 53.2 months in the non-IBD cohort (p = 0.056). The median DFS in the IBD cohort was 4.9 vs 9.4 months in the non-IBD cohort (p=0.174).
DISCUSSION: Cytoreductive surgery and heated intraperitoneal chemotherapy in patients with IBD has similar complication profile and trended towards poorer oncological outcomes as CRS/HIPEC in non-IBD patients.
