Background and Aims: We aimed to investigate the prognostic importance of the microvessel density (MVD) value, the vascular endothelial growth factor (VEGF) expression, and the presence of perineural invasion (PNI) in laryngeal cancer (LSCC) patients. Methods: Pathological specimens of 62 LSCC patients were assessed for the evaluation of the MVD value, the VEGF expression level, and the presence of PNI of the tumors. The tumor characteristics and prognostic effects of these parameters on local control (LC) and overall survival (OS) were analyzed. Statistical Analysis: Descriptive analyses were done using frequencies for the demographic variables. The survival estimates were calculated by the Kaplan–Meier survival curves. The effects of the parameters on LC and OS were investigated by using the log-rank test comparing the survival rates. Cox regression analysis was used for multivariable analysis. Results: The 5-year LC and OS rates of the 62 LSCC patients were 64.5 and 53.9%, respectively. Twenty-two patients (35.5%) had PNI and the frequency of PNI was higher in the patients with a high-grade disease (P = 0.01). The MVD value was higher in the tumors of older patients (P = 0.035) and was correlated with the VEGF expression (P = 0.009). A higher tumor grade was related to a higher VEGF expression (P = 0.01) and the increase in the VEGF expression was associated with a significant decrease in the OS (P = 0.03). Conclusion: The VEGF expression, the MVD value, and the presence of PNI had no prognostic significance on the LC in the LSCC patients while only the VEGF expression was associated with the OS.
