OBJECTIVE: The aim of this study was to investigate the diagnostic potential of Krebs von den Lungen-6 (KL-6) in differentiating between malignant pleural effusion (MPE) induced by non-small cell lung cancer (NSCLC) and benign pleural effusion (BPE).
METHODS: We collected 143 pleural effusion samples from August 2018 to March 2021. The samples included 91 cases of MPE and 52 cases of BPE. The KL-6 and other indicators in pleural effusion were detected.
RESULTS: The level of pleural effusion KL-6 (pKL-6) in the MPE group was significantly higher than in the BPE group (Mann-Whitney U = 442.500, P = .000). The area under the curve (AUC) of pKL-6/pleural effusion adenosine deaminase (pADA) + pleural effusion carcinoembryonic antigen (pCEA)/pADA (AUC = 0.992) in diagnosing MPE was higher than that of pKL-6 alone (AUC = 0.903), with a sensitivity of 93.26% and specificity of 100%.
CONCLUSION: The measurement of pKL-6 can differentiate NSCLC-induced MPE from BPE. Furthermore, the combined detection of pKL-6/pADA and pCEA/pADA can significantly improve the diagnostic efficiency for distinguishing NSCLC-induced MPE.
