ABSTRACT
OBJECTIVES: Laryngeal squamous cell carcinoma (LSCC) is a common squamous cell carcinoma of the head and neck with no reliable diagnostic biomarkers. However, recent studies have shown that inflammation plays an essential role in tumor development, and several inflammation-based biomarkers have been shown to have prognostic value. This study aimed to investigate t he auxiliary value of fibrinogen (FIB), fibrinogen degradation products (FDP), and lymphocyte/monocyte ratio (LMR) in LSCC diagnosis and prognosis.
METHODS: Clinical data from 218 patients recently diagnosed with LSCC and 207 diagnosed with benign laryngeal lesions (BLLs) were retrospectively reviewed. Potential diagnostic biomarkers were evaluated using univariate and multivariate analyses; receiver operating characteristic (ROC) curve analysis was used to identify cut-off values and diagnostic efficiency. Least absolute shrinkage and selection operator (LASSO) Logistic regression analysis was used to screen for independent risk factors to construct a diagnostic nomogram. The chi-squared test and Kaplan-Meier method were performed to investigate the correlation of clinicopathological characteristics and 3-year overall survival (OS) with FIB, FDP, and LMR in patients with LSCC.
RESULTS: FIB, FDP, and LMR levels were significantly different between the LSCC and BLL groups (P < .001), and all were independent risk factors for LSCC. The area under the ROC curve of the diagnostic nomogram was .894. Additionally, FIB, FDP, and LMR were correlated with some invasive clinicopathological features, and LMR ≥4.29 was associated with reduced OS (P = .038).
CONCLUSION: FIB, FDP, and LMR demonstrated potential as biomarkers for the diagnosis and prognosis of LSCC; however, further studies are needed to confirm their efficacy.
