Venous thromboembolisms and rheology in ovarian cancer patients after postoperative adjuvant paclitaxel and carboplatin therapy.

ABSTRACT

In ovarian cancer patients, chemotherapy can be an independent risk factor for the development of thromboembolic complications, such as venous thromboembolism (VTE). The factors and their values that lead to the development of VTE are remaining unknown in patients undergoing chemotherapy with paclitaxel and carboplatin. This study investigated serial rheological parameters (D-dimer, red blood cell count, hematocrit, and plasma viscosity) for VTE that developed following chemotherapy for ovarian cancer. Forty-eight ovarian cancer patients undergoing chemotherapy were enrolled in this study. A significant difference in the mean values of plasma viscosity and hematocrit was observed between the VTE group (n = 5) and the non-VTE group (n = 43) (P < 0.10). Univariate and multiple regression analyses by stepwise selection identified plasma viscosity as the independent variable associated with VTE development. The VTE incidence was the same as in previous reports. The results support the contention that plasma viscosity could be an index for development of VTE in ovarian cancer after chemotherapy.
