Introduction:
Peritoneal metastases (PM) can be treated with cytoreduction surgery (CRS) with intraoperative heated intraperitoneal chemotherapy (HIPEC) plus or minus early postoperative intraperitoneal chemotherapy (EPIC). HIPEC + EPIC may be associated with more complications than HIPEC alone.
Methods:
A prospective database of consecutive patients undergoing CRS + HIPEC ± EPIC at the University of Calgary between February 2000 and May 2011 was reviewed. Patient, tumor, and perioperative variables included peritoneal cancer index (PCI), completeness of cytoreduction (CCR) score, HIPEC ± EPIC type, and grade III/IV complications.
Results:
198 patients had a CCR score of 0/1 and received: (1) HIPEC mitomycin C + EPIC 5-fluorouracil for 5 days (n = 85; February 2000-January 2008); or (2) HIPEC oxaliplatin with IV 5-fluorouracil + no EPIC (n = 113; February 2008-May 2011). Clinicodemographics were similar except PCI was higher in the HIPEC-alone group (mean PCI 22 vs. 17; P = 0.02). The rate of grade III/IV complications was higher in the HIPEC + EPIC group (44.7% vs. 31.0%; P = 0.05). On multivariate logistic regression only HIPEC + EPIC and PCI > 26 were associated with an increased rate of complications.
Conclusion:
In patients with PM, the use of EPIC, in combination with CRS and HIPEC, is associated with an increased rate of complications. Surgeons should consider using HIPEC only (without EPIC).
