Background: Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is an increasingly utilized strategy for patients with peritoneal surface malignancies (PSM).
Methods: The US HIPEC Collaborative was retrospectively reviewed to compare the indications and perioperative outcomes of patients who underwent CRS ± HIPEC between 2000 and 2012 (P1) versus 2013-2017 (P2).
Results: Among 2,364 patients, 39% were from P1 and 61% from P2. The most common primary site was appendiceal (64%) while the median PCI was 13 and most patients had CCR 0 (60%) or 1 (25%). Over time, median estimated blood loss, need for transfusion, and length of hospital stay decreased. While the incidence of any (55% vs. 57%; p = 0.426) and Clavien III/IV complications did not change over time, there was a decrease in 90-day mortality (5% vs. 3%; p = 0.045).
Conclusion: CRS-HIPEC is increasingly performed for PSM at high-volume centers. Despite improvements in some perioperative outcomes and a reduction in postoperative mortality, morbidity rates remain high.
