Three ovarian-cancer-prone kindreds were studied, two of which contained identical twin sisters concordant for ovarian carcinoma. In one kindred, both identical twin sisters had daughters with ovarian carcinoma. In another kindred, one of the identical twin sisters had an ovarian-cancer-affected dau

โฆ Synopsis
Ovarian cancer is the leading cause of death from gynecologic cancer in the United States. Although the etiology of ovarian cancer is unknown, a number of factors including advancing age, nulliparity and environmental factors have traditionally been related to risk. More recently, genetic predisposition has been recognized as a strong risk factor for ovarian cancer. Three distinct hereditary syndromes have been identified: (1) breast-ovarian cancer syndrome, (2) hereditary nonpolyposis colon cancer, and (3) site-specific ovarian cancer. The mode of inheritance in these families is autosomal dominant with transmission occurring through either the maternal or paternal line. The breast-ovarian and site-specific ovarian cancer family syndrome have been linked to a gene on chromosome 17q that is called BRCAl .
However, no simple genetic test can identify women at high risk of the disease. For this reason, genetic counseling, education and surveillance with currently available screening techniques should be made available to women at high risk of ovarian cancer by virtue of their family history. In selected individuals, prophylactic oophorectomy may be warranted.

Ovarian cancer is the fourth leading cause of cancer deaths in American women. About 10% of cases are thought to have a hereditary basis, and family history is the strongest known risk factor. In the past, prophylactic oophorectomy has been advocated for women with two or more affected first-degree
There is increasing evidence that hereditary factors play a greater role in ovarian cancer than in any of the other common cancers of adulthood.
