Abstract: Objective

To explore the application values of simplified Wells score, revised Geneva score,and D-dimer(DD) level in the diagnosis of malignant tumor complicated with pulmonary thromboembolism (PTE),and to provide the reference for PTE diagnosis in clinic.

Methods

The clinical data of 142 cases of malignant tumor patients suspected of PTE and underwent CT pulmonary angiography (CTPA) examination were analyzed retrospectively. The diagnosis of PTE was based on the results of CTPA, and 72 patients with malignant tumor complicated with PTE were regarded as PTE group and 70 patients with malignant tumor without PTE were regarded as non-PTE group.The risk factors of all the enrolled patients were investigated through the statistical analysis,the receiver operating characteristic curves(ROC curves) were generated and the Z test was applied to compare the area under the ROC curve (AUC) of the above scores, and their values in the dignosis of malignant tumor complicated with PTE were evaluated.

Results

Adenocarcinoma,tumor metastasis,deep venous thrombosis (DVT) and positive DD were the independent risk factors for PTE in the patients with malignant tumor (P<0.05).The sensitivities of simplified Wells score,revised Geneva score, and DD level were 87.5%,87.5%, and 97.2%,respectively;the negative predictive values were 74.3%, 70.0%, and 83.3%,respectively. The sensitivities of the two clinical score scales combined with DD level reached 100%,the misdiagnostic rate was lower,and the negative predictive value reached 100% which was of great value for exclusion. The AUC of simplified Wells score,revised Geneva score,DD level, revised Geneva score combined with DD level,and simplified Wells score combined with DD level were 0.762,0.687,0.649,0.741,and 0.786,respectively.The AUC of simplified Wells score combined with DD level was the greatest, which was larger than those of the other scales (P<0.05).

Conclusion

Simplified Wells score combined with DD level shows a higher value in the diagnosis of malignant tumor complicated with PTE.

Key words: malignant tumor, pulmonary thromboembolism, simplified Wells score, revised Geneva score, D-dimer
