Abstract

The role of preoperative D-dimer in the prediction of postoperative venous thromboembolism (VTE) with gynecological tumor remains unclear. This meta-analysis sought to assess the association between preoperative D-dimer and the risk of VTE after gynecological tumor surgeries and to identify prognostic significance of D-dimer in the prediction of postoperative VTE. This study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 statement. Eight electronic databases were searched for cohort studies from the date of inception to April 2024. The Newcastle-Ottawa Scale scoring tool and the Risk of Bias in Non-Randomized Studies–Intervention tool were used to assess the quality of the literature and the risk of bias in cohort studies, respectively. The relative risk and 95% CIs of the highest vs the lowest category and per milligram per liter of D-dimer were pooled relative to the VTE risk after gynecological tumor surgeries. Fifteen studies that met the criteria were included. Among these studies, D-dimer was considered as a continuous variable in 8 studies. The random-effect model results showed that the VTE risk was increased by 42% (15%-69%) per milligram per liter increase in D-dimer. Furthermore, based on the cutoff thresholds of D-dimer, 7 studies that reported the effect estimates of postoperative VTE in women with gynecological tumor by D-dimer were categorized as binary variables. Compared with the reference levels, the pooled relative risk of VTE after gynecological tumor surgeries for the higher level was 2.58 (95% CI, 1.49-4.47). Elevated preoperative D-dimer was associated with higher VTE risks after gynecological tumor surgeries.
