November 18, 2008 Surgical Comments
� You need a complete cytoreduction.
� Having a complete cytoreduction does not guarantee a good outcome.
� We are able to achieve complete cytoreductions in about 50% of patients.
� More than likely, the complications are due to the extent of Surgery and not the HIPEC with Mitomycin

Nov 18, 2008 Systemic Therapy Comments
� Stage IV is Stage IV
� No need for subsets
� Do not recognize that intracoelomic dissemination is different than hematogenous dissemination
� However, we know that hematogenous dissemination is different than lymphatic dissemination
� We know that 1 positive LN is very different than 10 positive LN
� We know that 1 liver met is very different than 10 liver metastases

Current HIPEC Situation in the US

How are we going to get there
� By filling up the bucket with Data
� Practice Altering Data (PAD)
� Data with positive p values but, p values that are not only statistically significant but clinically significant.
� Prospective Randomized Trials that are powered to show PAD

Data, Precious Data
� The Power of Data
-Good Data is expensive, labor intense, takes too much time. (it can get old)
-Not needed in the opinion of some.
� The Power of NO Data
-Reduces cost for the insurance companies (short term)
-Prevents the establishment of guidelines which would clearly simplify patient care

PC in Colorectal and Gastric Cancer
� CRS and HIPEC is the gold standard treatment for colorectal cancer with PC…. when optimal CRS is achieved in an experiencedcenter.
PC (stage 1-2) from gastric cancer couldbe treated with CRS and HIPEC withinclinical trials : … still under evaluation.

Cytoreductive surgery and perioperative intraperitoneal chemotherapy for isolated colorectal peritoneal carcinomatosis: experimental therapy or standard of care?
Yan TD, Morris DL.
University of New South Wales, Department of Surgery, St. George Hospital,
Sydney, Australia.
The combined treatment for patients with isolated colorectal
peritoneal carcinomatosis should be considered to be the current standard of care.

HAI and HAIPEC
� HAI has continued to show benefits in the treatment of isolated hepatic metastases from colorectal cancer. Pharmacokinetic advantage. 100-400 fold FUDR
� The treatment requires multidisciplinary coordination between surgical oncology and medical oncology, technical expertise for safe dosing….
� Further trials are planned to explore HAI and systemic therapy to improve survival….
