Article Description

Background: Deep venous thrombosis (DVT) is associated with severe morbidity and mortality in cancer. Mean platelet volume (MPV) is an indicator of activated platelets. Objective: We aimed to investigate whether the combination of D-dimer and MPV could have a better performance in predicting deep venous thrombosis (DVT) in patients with breast cancer. MEHTODS: In 342 consecutive breast cancer patients without preoperative DVT, we measured the preoperative D-dimer and MPV levels. Compression ultrasonography was performed in all breast cancer patients before surgery, as well as one month, three months, six months, and twelve months. Results: During a median period of twelve months, 15 of the 234 patients (6.4%) developed DVT. MPV was reduced and D-dimer was increased in patients with DVT events compared to those without DVT. Multivariate Cox analysis revealed that both MPV and D-dimer were independent predictors for DVT events. The area under the ROC curve was 0.619 (95% CI: 0.553 to 0.681) when D-dimer was used alone, whereas it increased to 0.790 (95% CI 0.732 to 0.840, p < 0.001) with the addition of MPV. Conclusions: The combination of preoperative D-Dimer and MPV improves the predictive power of postoperative DVT risk in breast cancer patients.
