The aim of the present study was to determine whether expression of the CD44 variant v7-v8 (CD44v7-v8) or vascular endothelial growth factor-C (VEGF-C) is associated with long-term prognosis in breast cancer patients. A 10-year follow-up of 91 patients with primary breast cancer who were previously assessed for CD44 expression was undertaken. Immunohistochemical evaluation of VEGF-C expression was performed in 87 of these patients and their long-term prognosis was assessed. The disease-free and overall survival rates were significantly poorer for the CD44v7-v8-positive patients than for the patients negative for this marker. VEGF-C expression was detected in 38 out of the 87 patients (43.7%) with primary human breast cancer. There were no significant differences in tumor size, histological type, axillary lymph node status, presence of lymphatic or venous invasion, or presence of estrogen receptors and progesterone receptors between the VEGF-C-positive and -negative patients. There were also no significant differences in the disease-free or overall survival rates in these patient groups. In conclusion after the 10-year follow-up, expression of CD44v7-v8 was associated with poor prognosis for breast cancer patients. However, there was no association between VEGF-C expression and the clinicopathological factors or prognosis of breast cancer patients.
