['Tumour angiogenesis is the result of an inbalance between anti- and pro-angiogenic factors. CD105 (endoglin) is a component of the receptor complex of transforming growth factor (TGF-beta1). Vascular endothelial growth factor receptor 2 (VEGFR2 or Flk-1/KDR) belongs to the high-affinity VEGF receptors. The aim of the study was to investigate the expression, cellular localization and role of CD105 and VEGFR2 in laryngeal carcinoma.', 'Sections of 62 laryngeal carcinomas were stained with CD105 and VEGFR2/Flk-1/KDR antibodies.', 'A significant association between CD105 expression and locoregional recurrence was found (p = 0.009). Interestingly, in N0 patients CD105 expression was significantly associated with locoregional recurrence of the carcinoma (p = 0.03). The log-rank test showed a significant difference in the disease-free interval in patients stratified according to CD105 expression (p = 0.02). Statistical analysis showed no significant associations between vessel endothelial cell or laryngeal carcinoma cell VEGFR2 expressions and recurrence of disease or disease-free intervals.'] Are laryngeal carcinoma recurrence rate and disease-free interval related to CD105 expression but not to vascular endothelial growth factor 2 ( Flk-1/Kdr ) expression?
