Hemostatic and fibrinolytic status in patients with ovarian cancer and benign ovarian cysts: Could D-dimer and antithrombin III levels be included as prognostic markers for survival outcome?

Abstract

We determined the hemostatic and fibrinolytic status in 60 patients with ovarian cancer and benign ovarian cysts. Hypercoagulation, increased platelets, and enhanced fibrinolysis were seen in patients with preoperative ovarian cancer compared to patients with benign ovarian cysts. Enhanced thrombin generation, evidenced by increased F1+2 and decreased antithrombin III (ATIII) levels with further enhanced fibrinolysis by elevated D-dimer, was seen in advanced cancer. Ten ovarian cancer patients died within 13 months after diagnosis and another died at 24 months, all from advanced stage of cancer, except one from stage IC cancer who died at 11 months. The survival rates from the disease at 13 months and 24 months were 66.7% and 45%, respectively. Most of the patients had gone through the complete course of chemotherapy, and those patients still alive have been disease free between 13 and 42 months. No statistical relationships for the hemostatic parameters studied in ovarian cancer patients could be found between those who died and those still living 13 and 24 months after diagnosis, except for ATIII and D-dimer levels. Elevated D-dimer levels were associated with those who died within 13 and 24 months from the disease, and the decreased ATIII levels only reached statistical significance by 24 months. It could be suggested that these two parameters might be useful as systemic prognostic markers in survival outcome from the disease for the first 24 months in advanced ovarian cancer, in addition to the known correlation with the International Federation of Gynecology and Obstetrics stage.
