Ovarian Cancer Center
Mission:
•To provide exemplary and holistic clinical care to patients
with ovarian cancer.
•To enhance community awareness of ovarian cancer regarding
the importance of early diagnosis and the benefits of
centralized expert care.
•To advance the science of the prevention and treatment of
ovarian cancer in a meaningful way.

Peritoneal Surface Malignancies
 Disease confined to peritoneal cavity for
much of natural history
 Generally amenable to surgical resection
 Positive survival impact of chemotherapy
- varies by disease site

Development of Intra-Peritoneal (IP)
Chemotherapy
• 1950’s: First use of intraperitoneal
chemotherapy for malignant ascites
• 1968: Long-term peritoneal access device
• 1978: Demonstration of slow peritoneal
clearance of some drugs
• 1984: Feasibility of intermittent large volume
intraperitoneal therapy
• 1996: First report of a survival benefit for IP
vs. IV chemotherapy in advanced ovarian
cancer

Hyperthermia and Neoplasia
Heat is…
 Directly cytotoxic to cancer cells
- disrupts microtubule system
- induces primary protein damage
- promotes vascular stasis
 Synergistic with some chemotherapy agents

Discover ▪ Teach ▪ Heal
Role of HIPEC in Ovarian Cancer
 Retrospective study design (1995-2005)
 Advanced ovarian cancer (n=43)
 Up-front HIPEC cisplatin + IV chemotherapy
 Morbidity – 13.9%; mortality – 2.3%
 Median OS = 53 months
- complete initial resection = 131 months
 Median PFS = 39 months
