Abstract

BACKGROUND

Trousseau's syndrome is a prothrombotic state associated with malignancy that is poorly understood pathophysiologically.

METHODS AND RESULTS

Here we report studies on the blood of a 55-year-old man with giant-cell lung carcinoma who developed a severe form of Trousseau's syndrome. His clinical course was dominated by an extremely hypercoagulable state. Despite receiving potent antithrombotic therapy, he suffered eleven major arterial and venous thrombotic events over a 5 month period. We examined the patient's blood for tissue factor (TF), the major initiator of coagulation, and found its concentration in his plasma to be forty-one-fold higher than the mean concentration derived from testing of 16 normal individuals.

CONCLUSION

Almost all of the TF in the patient's plasma was associated with cell-derived microvesicles, likely shed by the cancer cells.

摘要

背景

特鲁索综合征是一种与恶性肿瘤相关的血栓前状态,其病理生理学机制尚不清楚。

方法与结果

在此我们报告对一名55岁巨细胞肺癌男性患者血液的研究,该患者发生了严重形式的特鲁索综合征。他的临床病程以极度高凝状态为主。尽管接受了强效抗血栓治疗,但在5个月内他仍发生了11次主要的动脉和静脉血栓事件。我们检测了患者血液中的组织因子(TF),它是凝血的主要启动因子,发现其血浆浓度比16名正常个体检测所得的平均浓度高41倍。

结论

患者血浆中几乎所有的TF都与细胞衍生的微泡相关,这些微泡可能是由癌细胞脱落产生的。
