Background• Gynaecologic sarcomas are very uncommon tumours.
– Uterine sarcoma 3 – 6% of uterine malignancies.– Ovarian sarcoma Less than 1% of ovarian tumours.
• Most of them are carcinosarcoma.• Less than 400 cases reported in the literature.• Ovarian carcinosarcoma usually present with advanced
disease.• Survival seems to be worse than epithelial ovarian cancer.• Monoclonal theory:
– The epithelial component begins tumorigenesis.– Sarcomatous component is a metaplastic event during the
evolution.• Objective: To analyse their clinical features and outcome.

Methods
• We analysed retrospectively patients with ginaecologycal sarcomas treated at our institution between 1978 and 2007.
• Minimun follow-up 1 y.• Retrospective data
collection using medical charts.
• All the cases were reviewed by a single expert pathologist.

Clinical features
• Median age: 63 years (45 – 77)
• Hormonal substitutive therapy in only 1 patient. (4 not known)

Treatment• All patients underwent total abdominal
hysterectomy and bilateral salpingoophorectomy.• Type of resection:
– 4 patients optimal cytoreduction – 8 patients suboptimal cytoreduction (including 1 stage IV
tumor)• Adjuvant chemotherapy:
– CDDP + Doxorubicine = 5– CYVADIC = 4– CBDCA – paclitaxel = 1– Ifosfamide = 1– Doxorubicine + Ifosfamide = 1
Platinum CT vs not: 6/6
Doxorubicine CT vs not: 10 vs 2

Results• Median Follow-up: 46 months• Nr of cycles: 6 (4-16)
• Relapsed patients: 7/11 ( 63 %)• Type Of Relapse:
– Local: 6/7– Distant + local 1/7
• Time To relapse: 48 (6-129) months• Treatment of relapsed disease
– Radical surgery + chemotherapy: 3/7 cases– Palliative chemoterapy: 4/7

Conclusions
• Due to the rarity of ovarian carcinosarcomas there are not prospective studies reported in the medical literature.
• The majority of retrospective analysis show that optimal surgery improves survival.
• The optimal chemotherapeutic regimen to treat this aggressive disease is yet to be determined. Most of the reviews recommend platinum based CTs.

Conclusions
• When feasible, aggressive approach for peritoneal recurrent disease should be considered.
• Prognosis of this infrequent disease seems to be worse than ovarian epithelial carcinoma, but in our series, probably due to the small number of cases, we have not found this result.
