title: Elevated preoperative plasma D-dimer levels and the incidence of venous thromboembolism in Japanese females with gynecological cancer.
abstract: The purpose of the present study was to determine the incidence of increased levels of D-dimer and associated factors in preoperative patients with gynecological cancer. Furthermore, we determined the incidence and risk factors associated with preoperative venous thromboembolism (VTE). Overall, 456 patients with invasive gynecological cancer scheduled to undergo surgery were recruited. Preoperative plasma D-dimer levels were measured and patients whose plasma D-dimer concentration exceeded the pre-set cut-off value underwent computed tomography scanning. The incidence of elevated D-dimer and VTE was identified as significantly higher in patients with ovarian cancer. Multivariate analysis revealed that advanced age, low hemoglobin levels and elevated C-reactive protein (CRP) levels were independent factors for preoperative elevations in plasma D-dimer levels. Advanced age was an independent risk factor for preoperative VTE. Massive ascites and the presence of co-morbidities were independent risk factors for preoperative VTE in ovarian cancer. Advanced age and stage were independent risk factors for preoperative VTE in endometrial cancer. Advanced age was an independent risk factor for preoperative VTE in cervical cancer. Plasma D-dimer levels and the incidence of preoperative VTE were higher in patients with ovarian cancer compared with those with other gynecological cancers. Advanced age, low hemoglobin levels and elevated CRP levels were significant factors associated with elevated plasma D-dimer levels and age was an independent risk factor for preoperative VTE in gynecological cancer.
