Gliederung

Text

Introduction: Laryngeal neoplasm represent 30–40% of the whole head and neck carcinomas. Mast cells are normal connective tissue residents, constantly well represented in respiratory tract. Experimental evidence suggests that the growth of a tumor beyond a certain size requires angiogenesis, which may also permit metastasis. The aim of this study was to evaluate the correlation between mast cell density, microvascular density, histopathological type and histological grade.

Methods: Our study included 38 laryngeal carcinomas. Histopathological diagnosis indicated the presence of the following types: adenoid cystic carcinoma (2 cases), malignant papilloma (4 cases) and squamous cell carcinoma (34 cases). The combined technique CD 34 – Alcian Blue Safranin (AAS) was used for identifying microvessels and mast cells density. Microvessel and mast cell density were calculated using the hot spot method.

Results: A significant correlation was found between mast cell density and G1, G2 histological grade (p=0.002). Partial correlation between microvascular density and G1, G2 histological grade (p=0.004) was noticed. The squamous cell carcinoma histopathological type was significant correlated with mast cell density (p=0.003), but not with the microvascular density (p=0.454).

Conclusions: The correlation between mast cell, microvascular density in the G1, G2 phase indicated a possible promotion of tumor progression by upregulation of angiogenesis.
