Peritonectomy/HIPEC has come a long way, we have positive RCTs in colorectal, gastric, ovarian, peritoneal disease and T4 CRC. We have refined indications, improved outcomes and much more data. Our St George Hospital CRS database has over 2000 procedures. PCI remains extremely prognostic in CRC with median survival for PCI <10 being 56m, 10-15 = 17m. In redo CRC, our median survival is 56m. Low grade appendix 201m and high grade 49m. EPIC in appendix is 248m vs 104m without. Redo in appendix is 189m low grade and 69m high grade. There is lots more to do.
