Background: This study aimed to investigate the incidence and risk factors for a prethrombotic state in patients with malignant tumors. Materials and Methods: Plasma d-dimer (D-D) in patients with malignant tumors was measured. Abnormal rates of D-D and possible risk factors like gender, age, type of tumor, and staging of tumor were analyzed. Results: Of 1,453 patients, 629 demonstrated plasma D-D abnormality (43.3%). The D-D abnormal rate of male patients (n=851, 43.5%) was not statistically significantly different from that for female patients (n=602, 43.0%) (p>0.05). D-D abnormal rate increased with age and was statistically significant among different age groups (p<0.05). Regarding staging of tumor, D-D abnormal rate in patients with phase I was 2.0%, 6.2% in phase II, 47.6% in phase III and 83.1% in phase IV, with statistically significant differences between phase III and II, as well as phase III and IV (p<0.01). Conclusions: A prethrombotic state was closely related to malignancy of tumors. The risk factors for a prethrombotic state include age and tumor stage.

Objective: To analyze the relationship between a prethrombotic state and the occurrence of thrombosis, as well as survival time for patients with cervical cancer. Methods: Patients with first diagnosis of cervical cancer were subgrouped according to FIGO staging, and two D-dimer levels were assessed. According to the results, patients are divided into an observation group (abnormal) and control group (normal). Results: For 106 patients with cervical cancer, 38 with abnormal D-dimer, the abnormal rate is 35.9%, of which stage I accounted for 6.5%, stage II 38.5%, stage III 50%, and stage IV 61.1% (p=0.013); The level of D-dimers in stageI wass $0.87{\pm}0.68ug/ml$, while in stage II it was $1.50{\pm}1.35ug/ml$, stage III $2.60{\pm}1.86ug/ml$ and stage IV $18.6{\pm}53.4ug/ml$ (P=0.031); after follow-up of patients for 2-30 months, the mortality of observation group is 21.1%, while for control group it was 2.94% (p <0.01). In the observation group, survival time was $15.1{\pm}5.8$ months, while for control group it was $21.0{\pm}5.4$ months, the difference between two groups being highly significant (p=0.000). Conclusion: There is a direct correlation between prethrombotic state and the grade malignancy of cervical cancer. The level is positively correlated with clinical stage, and is inversely related to survival time, so that a prethrombotic state could be used to predict the prognosis for patients with cervical cancer.
