 The patient and family must be:
aware of the problem

 Once the fertility has been
completed, demolitive procedure

Conclusions
 Abdominal way is possible
 The risk of recurrence is unchanged
 Fertility is preserved
 But pregnancies are at high risk
 An international study is required to
confirm indications and limits of this
conservative technique

Literature Overview (1966-2006)
 No pts.= 53
 80% were nulliparous
 In 96% of them the tumor was well
differentiated
 At least 36 pregn. were obtained by ART
 70% of pts. Underwent a hysterectomy
after completing gestation

 Diagnosis
Pre-operative?
Intra-operative frozen section?
Histopathological evaluation of

Fertility Sparing Surgery in Epithelial
Ovarian Cancer and Borderline Tumors
Optimal Staging:
 USO or cystectomy (in BOT)
 Peritoneal washing and cytology
 Inspection of the contralateral ovarian
surface, biopsies of any suspicious lesions
Wedge resection of the opposite ovary?
 Staging biopsies of the peritoneal cavity
 Sampling of retroperitoneal lymph nodes or
radical lymphadenectomy since 1990
 Omentectomy, appendectomy.

Borderline Tumors
 Recurrence rate in the patients
underwent conservative surgery
for border-line tumors is %7

 82 patients
 39 patients underwent conservative

would usually undergo radical operations.

CONCLUSIONS
 For more advanced stages, additional
investigation is needed.
 After completion of fertility, residual
ovary should be taken out.
 Incidence of ovarian cancer gets
higher with age.
 Screening method are unreliable.
Germ Cell Tumors of the Ovary
 Incidence: less than %5 of all
ovarian neoplasm.
 Age: the first and second decade
 Usually unilateral
FSS in Germ Cell Tumors of the Ovary
 1978 Forney first reported a case of
successful pregnancy in a 18 year-old with
EST of ovary.
Obstet Gynecol 52, 360-62 (1978)
 1985 Gershenson at the MD Anderson
Hospital.
48 patients with malignant germ cell
tumors
Full-term pregnancies in 6 cases
Cancer 56, 2756-2761 (1985)
FSS in Germ Cell Tumors of the Ovary
Rationales
 Unilaterality of tumor
 Improvement of prognosis by
modern combination chemotherapy
1970s the VAC regimen
1980s the PVB regimen
POMP/ACE.
Treatment of Malignant Ovarian Germ
Cell Tumors With Preservation of Fertility
A Report of 28 Cases / Cancer 42, 1152-1160 (1978)
 Tumor was confined to one ovary in all
cases.
 All patients were taken chemotherapy
except two with stage I immature
teratoma.
 More than 5 years survival in 13 cases
(59.1%)
 7 of 12 married patients, became pregnant,
all had term delivery.

Regardless of the stage is a safe
and practicable procedure in the
absence of involvement of

learn what should done
