%X Background: Survivin is an inhibitor of apoptosis that may be a novel diagnostic and prognostic marker
of cancer. Our study is to investigate the diagnostic and prognostic value of
survivin for pleural effusions. Methods: Sixty-five pleural effusion
patients were enrolled prospectively. Pleural effusion samples were examined for survivin level by ELISA. Pleural
effusions were divided into three groups:
Group I, malignant pleural effusion (MPE) (n = 36); Group II, tuberculous pleurisy
(TPE) (n = 18); and Group III, transudative pleural effusion (n = 11). The
accuracy of diagnosis and the correlation between survivin level and survival
in malignant pleural effusions (MPE) were analyzed. Results: Survivin level was 320.50 ¡À 228.24 pg/ml in MPE, 328.35 ¡À 146.79 pg/ml in TPE and 318.87 ¡À 208.39 pg/ml in
transudative pleural effusion respectively. ROC curves for MPE versus TPE were
analyzed, area under the ROC curve was 0.419, and for the cutoff value
of 254.85 pg/ml sensitivity was 44.4% and specificity 55.6%.
Survivin had no discriminative power in differentiating
exudative effusions of MPE from non-MPE (p = 0.648). There was no correlation
between survivin level and age, sex. However, statistically significant
difference was found between primary lung carcinoma (238.66 ¡À 48.19 pg/ml) and
extra-pulmonary metastatic carcinomas (435.09 ¡À 320.62 pg/ml) according to
survivin level (p = 0.033). Survivin levels can distinguish patients who had poor prognosis (median survival 96 days)
and those who had good prognosis (median survival 206 days) in MPE. Conclusio
