OBJECTIVE: To study the distribution and prognostic significance of microvessel density (MVD) in supraglottic laryngeal squamous cell carcinomas (SGLSCC).
METHOD: The patients of 59 primary SGLSCC received surgical treatment and 19 vocal cord polyps (VCP) were studied with CD31 immunohistochemical staining using Two Steps System Kits.
RESULT: There were many microvessels in the stroma of SGLSCC compared with the connective-tissue under epithelium of VCP. Kendall's ranked correlation analysis indicated that only MVD and nodal status had significant correlation (P<0.01) in all clinicopathological parameters. Both between N0 and N+ and between SGLSCC and VCP MVD were significantly different (P<0.01) by independent-samples t test. Kaplan-Meier survival analysis showed significant relationship existed in MVD and cumulative survival rate of SGLSCC patients (P<0.01).
CONCLUSION: This study further proves that angiogenesis plays important roles in tumorigenesis, invasiveness and metastasis. MVD could predict the lymph node metastasis and are significantly associated with the prognosis of SGLSCC patients.
