Aims:
Angiogenesis is essential for malignancies growth. CD105 is a proliferation-associated protein abundantly expressed in angiogenic endothelial cells. The aim of this study has been to determine the expression of CD105 in laryngeal squamous cell carcinoma (SCC) and to investigate the role of CD105-assessed mean vascular density (MVD) in predicting patients' prognosis.
Methods:
The sections of 43 consecutive cases of laryngeal SCC were stained with mouse monoclonal antibody CD105. All the measures were performed by a computer-based image analysis system. The percentage of the fields occupied by CD105-assessed micro-vessels was determined.
Results:
The mean CD105-assessed MVD were 11% and 6% in laryngeal SCC with and without malignancy recurrence, respectively. Multivariate logistic regression stated that CD105-assessed MVD was significantly related to disease recurrence (p=0.030).
Conclusions:
Our preliminary results suggest that CD105-assessed MVD may be a valuable parameter for predicting patients having an increased risk of developing laryngeal carcinoma loco-regional recurrence.
