Objective
To review our 25‐year experience with hyperthermic intra‐peritoneal chemotherapy (HIPEC).
Background
Combining cytoreductive surgery (CRS) and HIPEC as local treatments for peritoneal carcinomatosis (PC) was proposed 25 years ago.
Methods
A prospective database of all patients undergoing HIPEC for PC since 1989 was searched for clinicopathological data, 90‐day morbidity and mortality, and survival.
Results
Among 1,125 HIPEC procedures, PC origin was colorectal (342; 30%), ovarian (271; 24%), pseudomyxoma peritonei (189; 17%), gastric (127; 11%), malignant mesothelioma (84; 8%), or other (112; 10%). Between 2004–2009 (n = 321) and 2010–2015 (n = 560), the median peritoneal cancer index decreased (11 vs. 8; P < 0.001), fewer patients underwent incomplete cytoreduction (CC2‐3: 4% vs. 0.5%; P < 0.001), and more were included in randomized trials (5% vs. 16%; P < 0.001). Postoperative morbidity (52% vs. 50%, P = 0.672) was not different, but mortality significantly decreased (5% vs. 2%; P = 0.030). Median overall‐survival was 42 months, and improved significantly for each 5‐year period except for 2006–2010 vs. 2011–2015 (P = 0.097). The 10‐year survival without recurrence was 53%, 14%, 4%, 10%, and 9% for pseudomyxoma, mesothelioma, ovarian, colorectal, and gastric PC, respectively.
Conclusion
This study demonstrated that CRS and HIPEC provide long‐term survival irrespective of PC origin, and survival improves with experience. J. Surg. Oncol. 2016;113:796–803. © 2016 Wiley Periodicals, Inc.
