General Introduction
Ovarian tumors are commonest between 30 and 60.
They are particularly liable to be or to become malignant.
In their early stages, they are asymptomatic and painless.
They may grow to a large size.
1.4% lifetime risk of ovarian cancer

Incidence
Nearly 25% of all ovarian neoplasm are malignant.
Approximately 80 % of them are primary growths of the ovary.
The remainder being secondary , usually carcinomata.

symptoms
Lack of any specific symptoms, ovarian tumors are often large by the time the doctor is consulted.
Menstrual function is seldom upset, and any irregularity is attributed to the patient’s ‘time of life’.

General Rule
An experienced examiner will recognize an ovarian tumor mainly because ovarian tumor is, in the circumstances, the most likely diagnosis. All abdominal swellings should be subjected to ultrasound and X-ray examination.

ASCITES
A fluid thrill may be elicited from an ovarian cyst, and ascites and tumor may coexist; but as a rule the distinction should be easily made.

Uterine Fibroids
A large midline intramural fibroid may be impossible to distinguish from a solid ovarian tumor until the abdomen is opened and an entirely different surgical problem encountered.

Histological Classification Most tumors arise from the ovarian str
oma and germinal epithelium. The embryonic coelom from which that epithelium develops also gives rise to the Mullerian duct from which develop the structures of the genital tract, and it is this common origin which explains the great variety of epithelial patterns which are met with.

Krukenberg Tumor
There is one well-known secondary tumour of the ovary, the
krukenberg tumour, a secondary of a stomach carcinoma.
232006-11-1 七年制 Ovarian Cancer
Mucinous cystadenoma
A unilocular or multilocular cyst of ovary lined by tall columnar epithelium resembling that of the cervix or large intestine. It is usually large and may reach immense proportions, occupying the whole peritoneal cavity and compressing other organs. It may occur at any age.

OVARIAN TUMOURS --MUCINOUS CYSTADENOMA
252006-11-1 七年制 Ovarian Cancer
SEROUS CYSTADENOMA
A unilocular or multilocular cyst lined by epithelium similar to the fallopian tube. They are the most common benign epithelial tumors and form 20% of all ovarian neoplasm. In 10% of cases they are bilateral. It is uncommon to find them large than a fetal head.
262006-11-1 七年制 Ovarian Cancer
OVARIAN TUMORS --SEROUS CYSTADENOMA
272006-11-1 七年制 Ovarian Cancer
Serous cystadenocarcinoma
This is by far the commonest primary carcinoma, accounting for 60% of all cases, and in over half the cases it is bilateral. The cysts are always of papillary type and the epithelium burrowing through the capsule produces papillary processes on the serous surface. Extension of the growth to the pelvis and adjacent organs fixes the tumor. Ascites is always present.
282006-11-1 七年制 Ovarian Cancer
Endometrioid Carcinoma of the Ovary
It is now recognized that carcinoma of the ovary may be of endometrial type, sometimes arising in endometrioma. Attacks of pain, unusual with ovarian cancer, are common. Sometimes there is uterine bleeding in post-menopausal cases.
292006-11-1 七年制 Ovarian Cancer
Endometrioid Carcinoma of the Ovary
Usually the lesion is cystic and chocolate brown in color. If such a cyst ruptures spontaneously, malignancy should be suspected. The histology varies as in uterine carcinoma. It may be a well-differentiated adenocarcinoma, an adeno-acanthoma, mucinous adenocarcinoma or clear-celled carcinoma.
302006-11-1 七年制 Ovarian Cancer
Fibroma This is composed of fibro
us tissue and resembles fibromata found elsewhere. It is most common in the elderly and accounts for 4-5% of all ovarian neoplasm.
The fibroma is believed by many to be a thecoma which has undergone fibrous transformation. It is sometimes associated with Meig’s syndrome.
312006-11-1 七年制 Ovarian Cancer
Dysgerminoma This is the only solid ova
rian tumor of characteristic appearance. Usually ovoid with a smooth capsule, it is of rubbery consistency and greyish colour. It is commonest in younger age groups, under 30 years as a rule, and is often bilateral. Sometimes it is found in cases of intersex.

Estrogen-producing Tumors
These belong to the granulosa-theca cell group and are found at all ages. They account for 3% of all solid tumors of the ovary.
352006-11-1 七年制 Ovarian Cancer
Estrogen-producing Tumors In childhood there is accelerated skeletal
growth and appearance of sex hair. 5% occur in children precocious puberty. 60% occur in child-bearing years irregular
menstruation. 30% occur in post-menopausal women post-
menopausal bleeding.

Andorogen-producing Tumours
Three distinct types of masculinising ovarian tumor are recognised: a) Sertoli-Leydig cell tumor (Arrhenoblastoma), b) Hilar cell tumor, c) Lipoid cell tumor. All three cause amenorrhoea.

Spread -Direct
The first spread is directly into neighbouring structures – peritoneum, uterus, bladder, bowel and omentum.
382006-11-1 七年制 Ovarian Cancer
Spread -Lymphatics
Ovarian drainage is to the para-aortic glands, but sometimes to the pelvic and even inguinal groups. Cells seeded on to the peritoneum are drained via the lymphatic channels on the underside of the diaphragm into the subpleural glands and thence to the pleura.
392006-11-1 七年制 Ovarian Cancer
Spread -Blood Stream
Blood spread is usually late, to the liver and lungs.

TORSION of the PEDICLE
The commonest complication
Occur with any tumor
Except those with adhesions
462006-11-1 七年制 Ovarian Cancer
Clinical Features-Subacute
The patient complains of recurrent abdominal pain which passes off as the pedicle untwists. There is a rise in pulse and temperature during the bleeding; And over a period anemia develops.
TORSION of the PEDICLE
472006-11-1 七年制 Ovarian Cancer
Clinical Features-acute
The signs and symptoms are those of an acute abdominal condition. The problem becomes one of differential diagnosis to exclude those conditions in which laparotomy is not needed and laparoscopy may be useful.
Pain tends to be intense and continuous.
TORSION of the PEDICLE
482006-11-1 七年制 Ovarian Cancer
Ruptured Cyst This may occur alone or in conjunction with
torsion. Rupture is not particularly upsetting to the patient unless the contents are irritant.

492006-11-1 七年制 Ovarian Cancer
Suggestive of MalignancyAge. If the patient is over 50 the chance of
malignancy is over 50% as opposed to less than 15% in premenopausal women. Tumors in childhood are usually malignant.
Rapid growth.
Ascites.
502006-11-1 七年制 Ovarian Cancer
Suggestive of MalignancySolid tumours, especially when bilateral.Multilocular cysts with solid areas. (At least 1
0% of cysts are malignant).Pain. Pressure pain can occur with any tumor;
But referred pain suggests malignant involvement of nerve roots.
Tumor markers, such as CA125, may be measured in the blood, but a normal level does not exclude malignancy.

522006-11-1 七年制 Ovarian Cancer
Surgical Procedures
To classify the growth according to its extent of spread (staging) as accurately as possible.
To remove as much cancerous tissue as possible (‘surgical debulking’;’cyto-reductive treatment’).
532006-11-1 七年制 Ovarian Cancer
Surgical Procedures Benign ovarian over 10 cm in diameter m
ust be removed, but clinical and ultrasonically diagnosed cysts under 10 cm (the size of a lemon) in women under 35 years may be reviewed in a few months if there is no suspicion of malignancy. A follicular or luteral cyst may resolve spontaneously.

Follow-up Follow-up with intensive che
motherapy, using various combinations of antineoplastic drugs. Taxanes, probably combined with platinum compounds, are an appropriate first choice.

Second Look
A ‘second look’ laparotomy or laparoscopy operation (SLO), to determine the actual effectiveness of the chemotherapy and to decide whether it should be stopped does not affect prognosis, so should only be performed with informed consent in clinical trials.
592006-11-1 七年制 Ovarian Cancer
Surgical Procedures -Incision
A vertical incision which can be extended is essential to allow a full inspection. Reduction of a cyst by tapping and extraction through a suprapubic incision is not acceptable practice.
602006-11-1 七年制 Ovarian Cancer
Surgical Procedures - Cytology
Before handling the tumour, take specimens of ascitic fluid or peritoneal saline washings for cytological examination, and a cytology smear from the underside of the diaphragm.
