High expressions of CD105 and VEGF in early oral cancer predict potential cervical metastasis

Background and Objectives Although elective neck dissection has become a popular treatment modality for early oral cancer among most head and neck surgeons, a large portion of patients revealed pathological N0 postoperatively. Our study is aimed to evaluate the expressions of the angiogenic factors, vascular endothelial growth factor (VEGF), and CD105 (endoglin) on the prediction of neck metastasis for clinical N0 patients in early oral cancer. Patients and Methods Between July 1996 and July 2005, the preoperative biopsy specimens among 176 patients who underwent surgical treatment for early oral cancer were retrieved for the immunohistochemical study for VEGF and CD105. Results High expressions of CD105 and VEGF significantly correlated with positive nodal metastasis, respectively (P
