Abstract
The most common primary tumors were cancer of the breast and stomach. Fifty percent of gastric cancers and 41.2% of breast cancers caused metastases in the ovaries. Forty-one and seven tenths percent of ovaries removed from women with metastatic breast cancer revealed secondary tumors. The absolute number of tumor cases and of ovarian secondaries is larger after the age of 50 than before that age. Secondaries in ovaries are, however, more common in percentage, before the menopause. The deposit of ovarian secondaries in 64.8% took place by transperitoneal implantation. Bilateral implantation metastases are more common than unilateral ones. The haematogenic transmission occurred in 26.5%, before the age of 50 in 40%. The lymphogenic transmission of the mesovarium and the ovary is 8.7%. Haematogenic and lymphatic ovarian secondaries are more frequent unilateral than bilateral. A special group of ovarian secondaries characterized by sealring cells are known under the name of Krukenberg-tumors. The primary tumors are mostly, but not exclusively, found in the gastrointestinal tract. In these cases this was so in 13.5% of the ovarian secondaries.
