目的：探讨肺癌患者高粘血征的影响因素。方法：检测４３例肺癌患者血液流变学、凝血酶时间（ＴＴ），凝血酶原时间（ＰＴ），白陶土部份凝血活酶时间（ＫＰＴＴ），血小板最大聚集率（ＰＡｇＴ）及Ｄ－二聚体（Ｄ－Ｄ）。结果：４３例肺癌患者中３３例全血粘度增高，Ｄ－Ｄ增高者３３例，ＴＴ、ＰＴ、ＫＰＴＴ异常者分别是１８例、１５例、２２例。结论：引起肺癌高粘血征的主要因素是红细胞聚集指数（ＲＡＩ）以及硬度指数（ＴＫ）明显增高。血浆Ｄ－Ｄ水平与疗效及预后有关。
Objective: To explore the influencing factors of hyperviscosity in patients with lung cancer. METHODS: Hemorheology, thrombin time (TT), prothrombin time (PT), kaolin partial thromboplastin time (KPTT), platelet maximum aggregation rate (PAgT) and D-II were detected in 43 patients with lung cancer. Polymer (D-D). Results: Of the 43 patients with lung cancer, 33 had increased whole blood viscosity, and 33 had elevated D-D. The abnormalities of TT, PT and KPTT were 18, 15 and 22, respectively. Conclusion: The main factors causing the hyperviscosity of lung cancer are the marked increase of RAI and TK. Plasma D-D levels are associated with efficacy and prognosis.
