Ovarian cancer Sixth commonest cancer worldwide Fifth most frequent cause of cancer death The second most common gynecological cancer, after
endometrial cancer Approximately 1 in 70 newborn girls will develop
ovarian cancer during her lifetime 75% of women present with advanced disease Documented to occur in females of all ages.

Goals (Debulking)•Assessment of extent of disease
•Optimal tumor reduction
TAH = total abdominal hysterectomyBSO = bilateral salphingo-oophorectomy
What is conservative? To an interventionist it might mean
Traditional Old fashioned Unprogressive
But it also means Careful, Cautious and Preserving Protecting Saving
General PrincipleAny type of new managementwhich could impair the patients survival must not be employed if the “classic” treatments offer sure cure
What is conservative surgery in Ovarian Cancer?
Unilateral salpingo-oophorectomy
Full surgical staging Washings Omentectomy Appendectomy Node biopsies A thorough abdominal exploration and biopsy of any abnormal areas Endometrial biopsy should be performed to exclude endometrial cancer
Do not biopsy the contralateral ovary
Adjuvant chemotherapy?
Simply it should be called Fertility Sparing Surgery (FSS)
Sex cord - stromal tumors Malignant sex cord-stromal neoplasms are rare (1%)
Most commonly observed in postmenopausal period
Malignant neoplasms are generally considered to be low-grade
Disease was confined to the ovary in up to 95% of women
Conservative surgery is possible in a high percentage of young patients
Subsequent pregnancies have been documented only in case reports and small series (Powell et al)
Germ cell tumors Account for only about 5% of all malignant ovarian
neoplasms
Arise primarily in young women between 10 and 30 years of age
Most OGCTs (60%) are stage I at initial presentation
Most patients can be safely treated with Conservative surgery rather than radical one
Highly sensitive to platinum-based chemotherapy
The survival in advanced disease is still over 90%

Ovarian tumors of low malignant potential
Account for 10–15% of all epithelial tumors
Good prognosis, with a 10-year survival of approximately 90%
The median age is 15–20 years younger than that for invasive epithelial ovarian tumors
60% to 90% are stage I
Conservative surgery is possible in a high proportion of young patients

Invasive Epithelial Cancer The majority of ovarian malignancies (95%)
10-20 % of ovarian cancers occur before the age of 40 years.
The 5-year survival of patients with Stage IA, grade 1, EOC treated conservatively is 90%
Conservative surgery may be performed in selected young patients with apparent disease confined to one ovary

Sait et. al. Local Series A retrospective study of women conservatively treated for
primary ovarian cancer between January 2000 and December 2010 at King Abdulaziz University Hospital
39 patients 80% were stage I 52% were Germ cell tumor 8% patients had recurrent disease 20% had a normal pregnancy
Indications for FSS in ovarian cancer
Nonepithelial ovarian cancers
Ovarian tumors of low malignant potential
Early stage Epithelial ovarian carcinoma Stage IA G1-2
Future Perspectives The merged role of the treating physician as both life-save and
protector-of- future fertility has made the field of oncofertility a substantial part of gynecologic oncology nowadays
Prospectively designed and RCTs to evaluate safety of FSS are neither possible nor ethical
Our experience in outcomes after FSS mainly originates from retrospective case series
The gynecologic oncologist is in a unique position to provide young cancer patients with up-to-date fertility preservation information and fertility-sparing surgical alternatives
There is a need of close collaboration between cancer centers and reproductive centers in these cases
Conclusion After thorough insight of the current literature, FSS in
certain ovarian tumors appears a viable and safe option for women younger than 40 years who wish to preserve their childbearing potential
Only after thorough discussion and informed consent with careful balancing of the risks and benefits
The treating gynecologic oncologist should be fully aware of his double role in treating the malignant disease as well as in providing oncofertility care to young patients, by offering fertility-sparing alternatives when allowed so by tumor stage and histologic differentiation
