What are the considerations and management strategies for a patient undergoing an oophorectomy (ovary removal surgery)?

Oophorectomy: Key Considerations and Management Strategies

Indications for Prophylactic Oophorectomy

Prophylactic bilateral salpingo-oophorectomy should be performed in women with ≥20% lifetime ovarian cancer risk (including Lynch Syndrome carriers and BRCA mutation carriers) after age 35 once childbearing is complete. 1

High-Risk Populations Requiring Surgery

• Lynch Syndrome carriers: For women with MSH2 and MSH6 pathogenic variants, endometrial cancer risk by age 50 exceeds colorectal cancer risk, and ovarian cancer risk is substantial. 1
• Timing in Lynch Syndrome: Simultaneous hysterectomy with bilateral salpingo-oophorectomy may be performed at the time of colorectal cancer resection in women >35 years who have completed childbearing. 1
• BRCA mutation carriers: Women with documented BRCA mutations or strong family history gain substantial mortality benefit from prophylactic bilateral salpingo-oophorectomy. 2
• Age restrictions: Prophylactic oophorectomy is strongly contraindicated in women <35 years and in childless women <40 years unless hysterectomy is required for other medical indications. 1

Average-Risk Women Undergoing Benign Gynecologic Surgery

For women without elevated genetic risk undergoing hysterectomy, ovarian conservation is preferred in premenopausal women due to cardiovascular, bone health, and mortality benefits. 3

• Age-based approach: In women >49-50 years undergoing indicated gynecologic surgery, discuss prophylactic oophorectomy as this could prevent 4-10.9% of ovarian cancers depending on surgical access. 4
• Risk stratification required: The decision must incorporate individual cancer risk factors, comorbidity burden (cardiovascular disease, osteoporosis risk), and ability to comply with hormone replacement therapy. 5, 6

Mandatory Preoperative Counseling Elements

Genetic and Medical Assessment

• Family history documentation: Obtain detailed three-generation pedigree to identify hereditary cancer syndromes (Lynch Syndrome, BRCA mutations) that fundamentally alter surgical recommendations. 7
• Comorbidity inventory: Document cardiovascular disease status, bone density, diabetes, and other conditions that influence the risk-benefit calculation of premature menopause. 7

Informed Consent Discussion Points

• Incomplete protection: Patients must understand that prophylactic oophorectomy does not guarantee complete cancer prevention, as primary peritoneal cancer can still occur (failure rate is not negligible). 1
• Premature menopause consequences: For premenopausal women, bilateral oophorectomy causes immediate surgical menopause with significant impacts on bone health, cardiovascular health, sexual function, and quality of life. 7
• Hormone replacement therapy: Estrogen replacement should be discussed preoperatively for all premenopausal women, as it mitigates many adverse effects of premature menopause. 1, 7
• Age-specific HRT considerations: For women 40-50 years undergoing risk-reducing surgery, estrogen replacement therapy is particularly important to prevent negative sequelae. 1

Psychological Preparation

• Mandatory psychology consultation: A consultation with a psychologist from the multidisciplinary team must be offered prior to prophylactic surgery, particularly when mutation probability is not extremely high. 1
• Six-month reflection period: A mandatory 6-month waiting period is required before proceeding with prophylactic oophorectomy to ensure informed decision-making. 1
• Ongoing psychological support: Arrange appropriate psychological follow-up postoperatively given the sexual and psychological complications that may ensue. 1

Surgical Technique for Therapeutic Oophorectomy

Standard Oncologic Approach

For suspected ovarian malignancy, comprehensive surgical staging by a gynecologic oncologist through vertical midline incision is mandatory (Category 1 recommendation). 1, 8

• Peritoneal assessment: Perform ascites aspiration or peritoneal lavage for cytology immediately upon entering the abdomen. 1, 8
• Systematic exploration: Visualize all peritoneal surfaces including liver, diaphragm, omentum, paracolic gutters, and pelvis with selective excision or biopsy of any suspicious adhesions or peritoneal implants. 1, 2, 8
• Random biopsies: In the absence of visible disease, obtain random peritoneal biopsies from pelvis, paracolic gutters, and diaphragmatic surfaces (diaphragm scraping for cytology is acceptable alternative). 1, 8

Complete Surgical Procedure

• Standard resection: Total hysterectomy, bilateral salpingectomy, and bilateral oophorectomy with complete excision of lumbar-ovarian vessels bilaterally. 1, 2
• Omentectomy: Complete infragastric omentectomy is mandatory. 1
• Lymphadenectomy: Pelvic and para-aortic lymph node dissection should be performed, stripping nodal tissue from vena cava and aorta bilaterally to at least the inferior mesenteric artery level, preferably to renal vessels. 1
• Intact removal: Make every effort to keep encapsulated masses intact during removal, as rupture worsens prognosis. 1, 8

Fertility-Sparing Exceptions

Unilateral salpingo-oophorectomy with comprehensive staging may be considered only in select patients with stage IA/IB, grade 1-2, non-clear cell disease who desire fertility preservation. 1

• Mandatory staging: Complete staging procedure including contralateral ovarian examination, peritoneal biopsies, omentectomy, and lymphadenectomy must still be performed. 1
• Uterine assessment: Hysteroscopy and endometrial curettage are mandatory in all fertility-sparing cases. 1
• Special tumor types: For mucinous tumors, appendectomy should be performed and gastrointestinal tract carefully evaluated to exclude metastatic disease. 1

Fertility Preservation Considerations

Pretreatment Counseling Requirements

All patients of reproductive age must receive comprehensive fertility counseling before initiating any potentially gonadotoxic treatment. 1

• Information gaps: Early-onset cancer survivors often receive inadequate fertility counseling, particularly male patients. 1
• Risk assessment: Discuss risk of treatment-induced gonadal failure based on alkylating agent use, patient age, and baseline ovarian reserve (anti-Müllerian hormone levels, antral follicle count). 1

Fertility Preservation Options

• Ovarian transposition: Perform before pelvic radiotherapy to move ovaries out of radiation field. 1
• Gamete preservation: Offer sperm banking for males and oocyte/embryo cryopreservation for females. 1
• Ovarian tissue cryopreservation: Consider in appropriate candidates, though this remains investigational in some contexts. 1
• Timing considerations: Balance potential treatment delay risks against fertility preservation benefits, factoring in overall prognosis and pregnancy impact on recurrence risk. 1

Critical Pitfalls to Avoid

• Missing hereditary syndromes: Failure to obtain comprehensive family history may miss Lynch Syndrome or BRCA mutations that fundamentally change surgical recommendations and extent. 7
• Inadequate staging: Approximately 30% of apparent early-stage ovarian cancers are upstaged with comprehensive surgical staging, directly impacting treatment and survival. 8
• Omitting HRT discussion: Not discussing hormone replacement preoperatively leaves premenopausal women unprepared for managing severe premature menopause symptoms. 7
• Performing unnecessary oophorectomy: In average-risk premenopausal women, bilateral oophorectomy increases cardiovascular disease, osteoporosis, and all-cause mortality without commensurate cancer prevention benefit. 3
• Inadequate psychological preparation: Proceeding without psychology consultation and adequate reflection time increases risk of postoperative psychological complications and regret. 1
