BACKGROUND: Basic fibroblast growth factor (bFGF) is a potent angiogenetic factor which may influence breast cancer evolution. MATERIALS AND METHODS: Serum bFGF, (cut-off 10 pg/ml), was assayed in 166 breast cancer patients at all stages and compared with CA 15.3. RESULTS: In 99 pre-treatment (PT) sera, 39/99 (39.4%) were bFGF positive, 9/99 (9.1%) CA 15.3 positive (> 30 U/ml), and not correlated. No correlations were found between bFGF and age, menopausal status, TNM or pTNM, histology, SBR grading or steroid receptors. A postoperative decline in bFGF positivity, from 30.8 to 7.7% (n = 39), was observed. An abnormal CA 15.3 after primary treatment (n = 2/39) was of bad prognosis (P < 0.0001), whereas positive bFGF (n = 3/39) had no univariate prognostic value (median follow-up 5.5 years). During follow-up, positive bFGF was recorded in 6/92 (6.5%) disease-free patients (DFS), 13/15 (86.7%) regressions, 8/16 (50.0%) stable disease, and 46/67 (68.7%) progressive disease (significant differences between PT or DFS and post recurrence levels (P < 0.001), and between relapse before and after treatment (P = 0.002)). CONCLUSION: Serum bFGF is more often elevated before treatment or after relapse than in DFS, and rises under systemic treatments. Its pattern of variations does not add to CA 15.3 for breast cancer monitoring.
