Abstract
OBJECTIVE
Guanylate-binding protein 1 (GBP1) is reported to promote tumor progression and treatment resistance in lung cancer, and presents as a prognostic biomarker in several solid tumors. However, the related research of GBP1 in clinical management of lung adenocarcinoma is still lacking. Therefore, the present study aimed to detect the clinical role of GBP1 in lung adenocarcinoma.
METHODS
The clinical data of 221 lung adenocarcinoma patients were retrospectively analyzed, and then, their tumor tissue specimens and paired adjacent tissue specimens were retrieved for GBP1 detection via immunohistochemistry (IHC) assay.
RESULTS
GBP1 expression was upregulated in tumor tissues compared with adjacent tissues (P < .001). Moreover, high tumor GBP1 expression was associated with larger tumor size (P = .030), positive lymph node (LYN) metastasis (P = .001), advanced TNM stage (P = .001), and abnormal preoperative carcinoembryonic antigen (CEA) level (P = .026). Furthermore, tumor GBP1 high expression was correlated with reduced disease-free survival (DFS) and overall survival (OS), and was of independent value in predicting worse DFS and OS. Additionally, data analysis of 1144 lung cancer patients derived from KMplot database (www.kmplot.com) further verified that GBP1 expression was negatively correlated with OS (P = .009).
CONCLUSION
GBP1 correlates with advanced tumor features and worse survival profiles, suggesting its value to be a prognostic biomarker in management of lung adenocarcinoma.
