How is ovarian cancer classified?

How is ovarian cancer classified?

Ovarian tumors are classified as benign (non-cancerous), borderline or malignant (cancerous). Most epithelial ovarian tumors are benign and do not spread or cause cancer. There are many types of benign ovarian tumor, such as serous cystadenomas, mucinous cystadenomas, and Brenner tumors.

WHO classification ovarian cysts?

An ovarian cyst is a sac filled with liquid or semiliquid material that arises in an ovary. Such cysts can be broadly classified as either functional or neoplastic. Neoplastic ovarian cysts can be either benign or malignant.

What is Meigs?

In medicine, Meigs’s syndrome, also Meigs syndrome or Demons–Meigs syndrome, is the triad of ascites, pleural effusion, and benign ovarian tumor (ovarian fibroma, fibrothecoma, Brenner tumour, and occasionally granulosa cell tumour). Meigs syndrome resolves after the resection of the tumor.

Is Dysgerminoma malignant?

Dysgerminoma: This is the most common type of malignant ovarian germ cell tumor.

What are the 3 types of ovarian cancer?

There are three types of ovarian cancers: epithelial ovarian carcinomas, germ cell tumors, and stromal cell tumors. Each has different characteristics and traits: About 85% to 90% of these cancers start in the cells that cover the outer surface of the ovary.

Is ovarian cancer usually bilateral?

Cancer of the ovary is bilateral in 25%. Cytogenetic analysis could determine whether the disease in bilateral cases is metastatic or two separately occurring primary tumors, but karyotypic information comparing the two cancerous ovaries is limited to a single report with 11 informative cases.

What are the characteristics of a malignant ovarian cyst?

Malignant ovarian tumors tend to have papillary excrescences, irregular walls, and/or thick septations. The tumor can contain echogenic material arising from mucin or protein debris. The more solid the areas are, the greater the likelihood that a tumor is present.

What is a pathological cyst?

Pathological cysts are cysts caused by abnormal cell growth and aren’t related to the menstrual cycle. They can develop before and after the menopause. Pathological cysts develop from either the cells used to create eggs or the cells that cover the outer part of the ovary.

Is Meigs syndrome transudate or exudate?

The British Thoracic Society (BTS) statement on unilateral pleural effusion classifies pleural effusion in patients with Meigs’ syndrome as a transudate. The same opinion can be found in other review papers. Conversely, according to other authors, Meigs’ syndrome is associated with exudative pleural effusion.

Is Struma Ovarii a teratoma?

Struma ovarii is a specialized or monodermal teratoma predominantly composed of mature thyroid tissue [1].

Is dysgerminoma aggressive?

Dysgerminomas make up two thirds of all malignant ovarian neoplasms in women younger than 20 years. All dysgerminomas are considered malignant, but only one third of dysgerminomas behave aggressively. Their exact etiology has not been determined.

Is dysgerminoma curable?

This treatment produces less morbidity than chemotherapy and will cure approximately two-thirds of patients. Chemotherapy should be used for salvage of subsequent relapse. Both radiation and chemotherapy are highly effective treatment modalities for dysgerminoma.
