The development of distant metastasis in breast cancer patients is the key step towards worse prognosis. The angiogenic basic fibroblast growth factor (bFGF) has been associated with tumorigenesis and metastasis in several human cancers. Therefore, bFGF expression was studied by immunohistochemistry in 111 patients with primary breast cancer. The results were correlated with prognostically relevant clinico-pathological features. such as tumor stage, grading. nodal stage and survival. bFGF was expressed in approximately 70% of the breast cancer tissues; 30% of the tumors showed strongly positive staining. With the exception of histological grading (p < 0.05), no correlation was found between the extent of bFGF expression and prognostic parameters. Analysis of survival showed a significantly (p < 0.05) prolonged survival for patients with a concomitant absence of axillary lymph node metastasis and bFGF immunoreactivity. Our data suggest that increased bFGF expression is a novel parameter for worse prognosis in nodal-negative breast cancer patients.
