摘要

背景:肿瘤诱导凝血在癌症患者中广泛存在。此外,肿瘤诱导凝血与肿瘤发生、肿瘤进展和转移有关,因为它创造了一个增殖和促血管生成的微环境。因此,纤维蛋白降解产物 D-二聚体与多种癌症类型的肿瘤预后相关:本研究旨在探讨 D-二聚体水平是否可作为转移性乳腺癌(MBC)患者化疗反应的预测和监测指标:设计:这是一项前瞻性研究:本研究包括两组患者,分别是76名确诊为转移性乳腺癌的患者和25名原发性乳腺癌患者。在开始化疗前和第四个治疗周期后,对 MBC 患者的血浆 D-二聚体水平进行前瞻性测量。使用接收者操作特征曲线(ROC)分析化疗前(D0)的D-二聚体水平,以确定D0的最佳临界基线值,并评估其预测化疗反应的判别能力:在初步反应评估中,部分反应模式患者的 D-二聚体平均水平明显下降了 0.65 μg/ml,病情稳定患者的 D-二聚体平均水平下降了 0.5 μg/ml。在疾病进展组中,D-二聚体水平明显增加了 1.2 μg/ml。ROC曲线分析表明,D0时的D-二聚体水平可判别对化疗的反应,而疾病进展率与较高的D-二聚体水平相关:结论:血浆中的D-二聚体水平是预测和监测转移性乳腺癌化疗反应的有效指标。

D-dimer as a Predictive Biomarker of Response to Chemotherapy in Patients With Metastatic Breast Cancer.

Background: Tumor-induced coagulation is widely observed in cancer patients. Moreover, it is associated with tumorigenesis, tumor progression and metastasis, by creating a proliferative and proangiogenic microenvironment. Therefore, D-dimer, a fibrin degradation product, correlates with tumor prognosis in several cancer types.

Objectives: This study aims to investigate whether D-dimer levels can be a predictive and monitoring indicator for chemotherapy response in metastatic breast cancer (MBC) patients.

Design: This was a prospective study.

Methods: This study included two groups, 76 patients diagnosed with metastatic breast carcinoma and 25 patients with primary breast carcinoma. Plasma D-dimer levels were measured prospectively before chemotherapy initiation, and after the fourth treatment cycle in MBC patients. D-dimer levels before chemotherapy (D0) were analyzed using Receiver Operating Characteristic (ROC) curves to determine the optimal cut-off baseline values of D0, and to evaluate their discriminatory abilities in predicting response to chemotherapy.

Results: In the preliminary response evaluation, the mean level of D-dimer significantly decreased by 0.65 μg/ml in patients with partial response patterns, and by 0.5 μg/ml in patients with stable disease. In the disease progression group, a marked increase was seen in D-dimer levels by 1.2 μg/ml. Analysis of ROC curves showed that D-dimer levels at D0 could discriminate the response to chemotherapy, whereas progressive disease rate correlated with higher levels of D-dimer.

Conclusion: D-dimer level in plasma is a useful predictive and monitoring marker of response to chemotherapy in metastatic breast cancer.
