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
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

C- 43 Additional Slides
C- 44 Ovarian Cancer Epidemiology Age adjusted incidence is 2 to 15 cases per 100,000 women Incidence rates are stable or slowly increasing
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):
C- 46 Ovarian Cancer Age at presentation is bimodal with peaks at age 40 and 60 years old Symptoms often are nonspecific: –Abdominal bloating –Pelvic pressure –GI symptoms –Respiratory –Constitutional
