What type of cancers are reduced due to salpingectomy?
Clear Cell and Endometriod primarily
Risk Reducing BSO
decreased ovarian by 96% and Breast by 53%
Risk of primary peritoneal cancer after
salpingo-oophorectomy: 4%
Occult ovarian cancer at the time of surgery:
2-17%
BRCA1 35-40
BRCA2 40-45
Can consider for other genes for ovarian ca like lynch
Screening for high risk for ovarian cancer
CA 125 and U/S every 6 months
Which ovarian cancer patients should have genetic testing
ALL
ovarian cancer work-up
Most helpful imaging:
Pelvic ultrasound
CT abdomen/pelvis with PO and IV contrast
Most helpful labs:
CA-125, CA 19-9, CEA
Inhibin B, HCG, AFP, LDH, testosterone (if younger, solid
mass, or hyperestrogenism/androgenism)
Staging surgery for Ovary
Vertical midline incision Obtain peritoneal cytology Intact tumor removal Complete abdominal exploration Removal of remaining ovaries, uterus, tubes Pelvic/para-aortic lymphadenectomy Omentectomy Random peritoneal biopsies Appendectomy (particularly if mucinous)
Very Basic Ovary Staging
1- overy
2- Pelvis
3- beyond pelvis (nodes or microscopic mets)
4- Distant
Chemotherapy for ovarian
Stage 1 grade 1- observe stage 1 grade 2- observe or chemo Stage 1 grade 3- Carbo/taxol 3-6 cycles Stage 1c- carbo/taxol 3-6 cycles Stage II-IV - Carbo/taxol 6-8 cycles Neo- 3-4 cycles (surgery) 3-4 cycles
What is the response rate for chemo?
75-80% respond to chemo
What is platinum resistance?
recurrence <6 months
What are maintenance therapy options?
PARP inhibitors (DNA repair)- genetic mutations
Bevacizumab (VEGF antibody)
Pazopanib
Surveillance with ovarian Cancer
Visit with exam every 3 months x 2 years, 6 months x 3 yrs
CA-125 optional
Imaging if concern for recurrence
