RESUMO
BACKGROUND: Textbook oncologic outcome (TOO) is a composite metric shown to correlate with improved survival after curative intent oncologic procedures. Despite increasing use among disciplines in surgical oncology, no consensus exists for its definition in cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). STUDY DESIGN: An international consensus-based study employed a Delphi methodology to achieve agreement. Fifty-four senior surgeons from the peritoneal surface malignancies field received a questionnaire comprising TOO parameters divided into 3 surgical domains: operative, short-term, and long-term postoperative outcomes. Two online meetings with participants defined the new criteria. Consensus was achieved when 75% of agreement rate was reached. Clinical data of patients who underwent CRS and HIPEC for colorectal peritoneal metastasis between 2010 and 2022 from 1 designated center (Sheba Medical Center) were collected, the consensus definition applied and outcomes analyzed. RESULTS: Thirty-eight surgeons (70%) participated. Expert consensus TOO parameters for colorectal peritoneal metastasis CRS and HIPEC included the absence of unplanned reoperations during 30 days postoperation, absence of severe postoperative complications (Clavien-Dindo ≥III), absence of unplanned readmissions during 30 days postoperation, 90-day postoperative mortality, and absence of contraindications for chemotherapy within 12 weeks from operation, and included the achievement of complete cytoreduction (CC0). The study cohort consisted of 251 patients, and 151 (60%) met TOO criteria. Patients who achieved TOO had significantly better overall survival (median 67.5 months, 95% CI) vs patients who did not achieve TOO (median 44.6 months, 95% CI, p < 0.001) and significantly improved disease-free survival (median, 12 months, 95% CI, vs 9 months, 95% CI, p = 0.01). CONCLUSIONS: Achievement of TOO as defined by consensus statement is associated with improved survival.

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.
