Ali AYHAN, MD Baskent University School of Medicine Department of Obstetrics & Gynecology Division of Gynecologic Oncology Fertility Sparing Surgery (FSS) Gynecologic Oncology in

The Main Purpose of Cancer Therapy High cure Low morbidity High level quality of life (as a mood, sexuel life, cosmetic appearence, fertility preservation...)

All Therapeutic Modalities in Female Cancer are associated with infertility (radiation, radical surgery, chemo...)

Therefore Fertility saving surgery instead of radical in early stage selected gynecological cancers is performed by different centers

FSS Objectives similiar oncologic outcomes to standard therapy favorable obstetric outcome benefits > risks low morbidity and cost

Benefits-Risks of FSS Benefits Preservation of fertility Maintanence of endocrine function Risks Increase in probability of recurrence and death Additional surgery

The Main Requirement of FSS preserving of the uterus preserving at least one ovary

Fertility Saving Surgery Depends on Type and origins of tumor Stage, grade, histology Age, performance Fertility desire Previous infertility problems Close follow up

Indications for Fertility Saving Surgery All germ cell Sex cord stromal (early stage) Borderline ovarian tumor Invasive EOC Cervical Carcinoma Endometrial Carcinoma

Fertility Saving Surgery in Ovarian Tumors (EOC, BOT,MOGCT, Sex Cord Stromal) Comprehensive surgical staging Removal of affected ovary and tube Preservation of uterus and contralateral ovary Finally evaluation of normal appearing contralateral ovary* and endometrium (D&C)** * For occult metastases ** Endometrioid type of epithelial tumors

FSS in EOC 14% of EOC will occur under 40 years 25-30% of all EOC are early stage at the diagnosis Of these 62% will be stage I and IIa Not all, many of these desire to preserve fertility SO TODAY; PROBLEM IS SMALL

Indication for Fertility Sparing Surgery in EOC 1.Stage Ia, Grade 1 Stage Ia, Grade 2 (limited) 2.Stage Ic, Grade 3, Clear cell + Chemotherapy

Main Problems in FSS in EOC A)In preserved ovary 1) occult metastasis 2) relapse in spared ovary B) Is there any relationship between relapse, death and preservation of ovary, uterus or other risk factors C) Is there a place of complementary surgery after childbearing

Occult Metastasis in Normal Appearing Ovaries varies from 6-12% in old literature in the new literature, this figures are about 2.5% in stage I disease Gynecologic Oncology, 2008:110,
