Ovarian cancer is the most common cancer of the female reproductive system. Risk factors include family history of ovarian or breast cancer, genetic factors, older age, and increased number of menstrual cycles. Symptoms are often vague in early stages but may include abdominal bloating, pressure, and pelvic pain. Diagnosis involves pelvic exam, ultrasound, CT scan, and CA125 blood test. Treatment consists of surgery to stage the cancer and remove tumors, followed by chemotherapy.

- 1. Ovarian Cancer Dr.Saleh Bakar Taishan Medical University, Taian, Shandong, China
- 2. 2 Ovarian Cancer 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
- 3. 3 Ovarian Cancer Risk Factors Family history Ovarian cancer Breast cancer Colon cancer Genetic factors Older age Caucasian More menstrual circles during lifetime (Ovulation induction)
- 4. 4 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.
- 5. 5 Ovarian Cancer by dr Saleh Bakar 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’.

- 10. 10 Ovarian Cancer CLINICAL FEATURES OF OVARIAN TUMOURS
- 11. 11 Ovarian Cancer 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. DIFFERENTIAL DIAGNOSIS
- 13. 13 Ovarian Cancer 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. DIFFERENTIAL DIAGNOSIS
- 14. 14 Ovarian Cancer 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. DIFFERENTIAL DIAGNOSIS
- 18. 18 Ovarian Cancer Histological Classification Most tumors arise from the ovarian stroma 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.
- 19. 19 Ovarian Cancer Primary Epithelial TumorMucinous cystadenoma or cystadencarcinoma (of. Cervical epithelium). Serous cystadenoma or cystadenocarcinoma (of . tubal epithelium). Endometrioma or Endometrioid carcinoma (of. Endometrium). Clear cell carcinoma. Brenner tumour. Squamous cell tumor

- 22. 22 Ovarian Cancer Krukenberg Tumor There is one well- known secondary tumour of the ovary, the krukenberg tumour, a secondary of a stomach carcinoma.
- 23. 23 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.
- 26. 26 Ovarian Cancer VARIAN TUMOURS --MUCINOUS CYSTADENOMA
- 27. 27 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.
- 30. 30 Ovarian Cancer VARIAN TUMORS --SEROUS CYSTADENOMA
- 31. 31 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.
- 32. 32 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.
- 33. 33 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.
- 34. 34 Ovarian Cancer Fibroma This is composed of fibrous 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.
- 35. 35 Ovarian Cancer 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.
- 36. 36 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.
- 37. 37 Ovarian Cancer Andorogen-producing Tumours Three distinct types of masculinising ovarian tumor are recognised: a) Sertoli- Leydig cell tumor (Androblastoma), b) Hilar cell tumor, c) Lipoid cell tumor. All three cause amenorrhoea.
- 38. 38 Ovarian Cancer Dysgerminoma This is the only solid ovarian 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.

- 51. 51 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.

- 64. 64 Ovarian Cancer TORSION of the PEDICLE The commonest complication Occur with any tumor Except those with adhesions
- 65. 65 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
- 66. 66 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. ORSION of the PEDICLE
- 67. 67 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. TORSION of the PEDICLE
- 68. 68 Ovarian Cancer Suggestive of Malignancy Age. 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.
- 69. 69 Ovarian Cancer Suggestive of Malignancy Solid tumours, especially when bilateral. Multilocular cysts with solid areas. (At least 10% 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.

- 72. 72 Ovarian Cancer Surgical Procedures Benign ovarian over 10 cm in diameter must 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.

- 76. 76 Ovarian Cancer Follow-up Follow-up with intensive chemotherapy, using various combinations of antineoplastic drugs. Taxanes, probably combined with platinum compounds, are an appropriate first choice.
- 77. 77 Ovarian Cancer 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.
- 78. 78 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.
- 79. 79 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.
