Abstract
BACKGROUND: To investigate the value of Ubiquitin specific peptidase 8 (USP8), Chitinase 3-like 1 (YKL40), Heat shock protein 90a (HSP90α), glutathione S-transferase P1 (GSTP1), carcinoembryonic antigen (CEA), neuron specific enolase (NSE) and cytokeratin fragment antiogen 21-1 (CYFRA21-1) in bronchoalveolar lavage fluid (BALF) and serum for diagnosis in patients with peripheral lung cancer. METHODS: The concentration of these markers were measured in 50 patients with peripheral lung cancer and 50 patients with benign lung diseases by using enzyme-linked immuno sorbent assay methods. RESULTS: There were significant differences between the peripheral lung cancer group and the benign lung disease group (P < 0.05) in the BALF of USP8, YKL40, HSP90α, CEA, NSE and CYFRA21-1. There were significant differences between the peripheral lung cancer group and the benign lung disease group (P < 0.05) in the serum of HSP90α and CEA. There were no differences in others. There were no correlation between the concentration of all markers and age, histological type, TNM stage (I-IV). There was a weak correlation between the primary foci diameters and the concentration of YKL40 in BALF. (Pearson's correlation: 0.203, P = 0.048) The diagnostic efficiencies of USP8, YKL40, HSP90α were superior to CYFRA21-1 and NSE, being lower CEA. CONCLUSION: Detection of tumor markers in BALF was superior to serum specimens. The measurement of USP8, HSP90α and YKL40 in BALF had more clinical value for the diagnosis of peripheral pulmonary carcinoma.
