14 C- 14 The Optimal Care for Ovarian Cancer Cytoreductive surgery with complete surgical staging Rationale for surgical staging: –Define the extent of disease –Determine the need for adjuvant treatment –Provide prognosis –Outline a plan of care

15 C- 15 Surgical Debulking Increases Survival for Ovarian Cancer Optimal surgical debulking can include: Hysterectomy Removal of ovaries Bowel resection Peritoneal stripping Diaphragmatic stripping Lymph node debulking

16 C- 16 Gynecologic Oncologists are Ovarian Cancer Specialists Gynecologic oncologist –Recognized sub-specialty in US Residency in Obstetrics and Gynecology (4 yrs) Fellowship in Gynecologic Oncology (3-4 yrs) –Outside US Gynecologists with high oncology surgical volume Experienced in: –Surgical care –Medical management –Chemotherapy –Natural history

23 C- 23 Current Practice is Sub-Optimal for Ovarian Cancer Patients In the US only 50% of women with ovarian cancer are operated on by high volume surgeons or at high volume centers 1 Studies around the world show that survival rates are improved when patients have surgery by surgeons and at centers experienced in the management of ovarian cancer 2 1 Goff BA et al.

43 C- 43 Additional Slides

44 C- 44 Ovarian Cancer Epidemiology Age adjusted incidence is 2 to 15 cases per 100,000 women Incidence rates are stable or slowly increasing

45 C- 45 Surgical Staging The current standard of care for ovarian cancer is cytoreductive surgery with complete surgical staging. Complete surgical staging includes: –Laparotomy –Hysterectomy –Bilateral salpingo-oophorectomy –Careful evaluation of all peritoneal surfaces –Multiple washings for cytology –Multiple peritoneal biopsies –Hepatic and diaphragmatic cytology –Omentectomy –Pelvic and periaortic lymphadenectomy Less than 50% of women undergoing surgery for an ovarian cancer will have an adequate staging or cytoreductive surgery 1,2. Gynecologic Oncologists are trained in staging of ovarian cancer. 1 Carney ME et al. Gynecol Oncol. 2002;84: McGowan L et al. Obstet Gynecol. 1985;65(4):
