2. Pathologic behavior :
Non neoplastic
Neoplastic
(benign,malign, borderline).
Morphology(cystic,solid).
Histogenesis.
3. Ovarian tumours Neoplastic
Epithelial T
Germ cell T.
Sex cord T
others( Metastatic.)
4. SEX CORD-STROMAL TUMORS( SCTS)
5. SEX CORD-STROMAL TUMORS SCTS are 15% of all malignant ovarian neoplasm
The vast majority of these tumors are of low malignant potential or benign.
Long term prognosis is good.
Excessive estrogen production influences end organ responses.
Endometrial and breast cancer must be remembered.
6. SEX CORD-STROMAL TUMORSCLASSIFICATION Granulosa cell tumor
Adult
Juvenile
Thecoma-fibroma
Thecoma
Fibroma,sarcoma
Sclerosing stromal tumor
7. Granulosa Cell Tumor:
8. Gonadal Stromal tumours
9. Metastatic Tumors of Ovary
12. Krukenberg Tumor:
13. Endometrioid Ca:
14. complications of benign ov Tumours torsion
hemorrhage
rupture
infection
incarceration
malignant change
complications during pregnancy
15. Diagnostic tools History
Exam (including rectal)
Investigations:-
TVS masses and mass characteristics
Tumor markers CA-125, LPA (plasma lysophosphatidic acid)
CT assess spread to LN, pelvic and abdominal structures
MRI best for distinguishing malignant from benign tumors
16. Clinical picture of benign ov tumors Symptoms:
functioning tumors
nonfunctioning tumors
swelling
pressure symptoms
pain
menstrual disturbances
ovarian cachexia
Signs
small ov tumors
large ov tumors
DD:
from other pelvic swellings
from other abdominal swellings
17. Clinical picture cancer ovary Benign ovarian Tumours + The following suggest malignancy
age:mostly postmenopausal
pain: chronic and persistent
rapid course
bilaterality
Solidity ( variegated consistency )
fixity
metastases :nodules in DP, lymph nodes
ascitis
edema LL
cachexia
18. Treatment Depends on
Staging
Tumor type
Age
Desire for future fertility
Include surgery, chemotherapy and/or radiation therapy
19. Surgery for ov. cancer Conservative surgery: unilateral adnexectomy indicated:
stage Ia: intact capsule, negative peritoneal washing, free omentum,
well differentiated T,
young patient with low parity
Complete surgery:TAH/BSO +omentectomy+lymphadenectomy
other cases of stage Ia
Stage Ib,c
20. Surgery for ov. Cancer cont Cytoreductive surgery: for all other stages
optimum cytoreduction leaving no macroscopic lesion or one less than 1.5 cm.
consist of TAH/BSO +omentectomy+lymphadenectomy+may be bowel resection & anastmosis.
Second look surgery after chemotherapy
21. Surgical treatment Primary debulking and cytoreduction; may include:
Bilateral salpingo-oopherectomy
Hysterectomy
Lymphadenectomy (Para-aortic, inguinal)
Omentectomy
brushing of diaphragm
Examination of liver
22. Chemotherapy & radiotherapy for ov cancer Chemotherapy:
adjuvant to surgery to improve prognosis in early stages
induce remission in advanced cases
agents: alkylating agents,platinum: single drug and multible drug regimens
23. Chemotherapy & radiotherapy for ov cancer cont Radiotherapy:
has less place in modern practice, replaced by chemotherapy
was given for cases with small residual lesions (< 2 cm)
forms are:
radioactive isotope: intraperitoneal 32P ,
external-beam radiotherapy
24. Chemotherapy and Radiation Usually 6 cycles of chemotherapy
Cisplatin (or Carboplatin) plus Paclitaxel most commonly used combination therapy
XRT
