Relative frequency of primary ovarian neoplasms: a 10-year review

Article Abstract:

The relative frequency of various types of ovarian neoplasms (tumors) in a population of 861 primarily Hispanic women is reviewed. The patients were treated at one medical facility over a 10-year period; their average age was 36. Twenty-two percent had neoplasms on both ovaries, while the remainder had neoplasms on one side only. The sizes of these neoplasms varied; average dimensions were 9 by 10 centimeters. Three-quarters of the patients had benign neoplasms. Thirty-one patients had neoplasms with low potential to become malignant, and the remainder (180 patients) had malignancies. One-fourth of the patients were postmenopausal, of whom 95 (45 percent) developed malignancies. Thirteen percent of the 649 premenopausal patients had malignancies. The risk of a malignant ovarian neoplasm was increased by a factor of 3.4 for postmenopausal, as compared with premenopausal, women. This risk also increased with age; while 94 percent of all neoplasms among women aged 20 to 29 were benign, this was true of only 47 percent of the neoplasms in women aged 60 to 69. Women in this older category had a 12.1-fold increased risk of having a malignant neoplasm, as compared with the youngest women. The cell types most commonly encountered are enumerated. Benign cystic teratoma was the most common benign condition overall (58 percent), and serous cystadenocarcinoma was the most common malignant condition (43 percent). These results represent all cases seen at a large women's hospital and provide statistics regarding ovarian neoplasms in an extensive patient population.

Relative frequency of malignant parovarian tumors: should parovarian tumors be aspirated?

Article Abstract:

Parovarian tumors, tumors arising in the tissue near the fallopian tubes and the ovaries, can be cancerous or noncancerous. Some surgeons have advocated pulling fluid from parovarian tumors (aspiration) during laparoscopy, a procedure in which a small tube with a magnifying lens is inserted into the abdomen to visualize and manipulate internal structures. However, if the tumor is cancerous, there is a danger of spilling cancer cells into the abdominal cavity during aspiration. The frequency of parovarian cancerous tumors was studied among 168 women diagnosed with parovarian tumors within a ten-year period. Most of the women (98 percent) had benign tumors and three women (two percent) were diagnosed as having cancer. In addition, most of the women (91 percent) were premenopausal, or of child-bearing age. The women with cancer were characteristically premenopausal, with tumors larger than five centimeters (two inches) which contained papillary projections inside the tumor. In two of the three cases of cancer, the fluid obtained from the cysts did not contain cancerous cells. The value of aspiration of parovarian tumors to analyze the cyst fluid and detect malignancy is questionable. (Consumer Summary produced by Reliance Medical Information, Inc.)

Ovarian neoplasms and the risk of adnexal torsion

Article Abstract:

Adnexal torsion is a condition in which the tissues supporting the ovaries and fallopian tubes twist. It is possible that benign ovarian tumors (neoplasms) more commonly precede adnexal torsion than malignant tumors, but this has not been studied systematically. To learn more about this possibility, the medical records were reviewed from 861 women diagnosed with ovarian neoplasms during a 10-year period at one medical institution. The rate of torsion, defined as a rotation of the adnexa of at least 360 degrees, was evaluated. This was identified in 98 of the patients, of whom 93 (95 percent) had benign ovarian neoplasms, and 5 (3 percent) had neoplasms that were malignant or of low malignant potential. Thus, it appears that benign ovarian neoplasms are far more likely than malignant ones to become involved in adnexal torsion. This may be a result of the low incidence of malignant tumors, or of the adherence of such tumors to surrounding tissues, preventing torsion. These findings should be considered when decisions are made regarding patient treatment. (Consumer Summary produced by Reliance Medical Information, Inc.)
