AB  - Background: The role of circulating TGF-beta(1) in prognosis of breast cancer (BC) was investigated with an intention to define TGF-beta(1)-dependent high risk and low risk subsets of patients. Methods: Fifty three BC patients of all clinical stages and 37 healthy donors (HD) were analyzed for plasma TGF-beta(1) by the T beta RII receptor-based Quantikine TGF-beta(1) ELISA kit. Results: The plasma TGF-beta(1) level of Stage I/II disease (median: 0.94 ng/ml; n=10)) remained close to HD (median: 1.30 ng/ml; n = 37; p GT 0.1). In contrast, Stage III/IV disease (median: 2.34 ng/ml; n=43) exhibited highly significant TGF-beta(1) elevation (p LT 0.001) relative to HD. Further analysis revealed that TGF-beta(1) increase was predominantly attributed to Stage IV, metastatic disease patients (Q3=4.23 ng/ml) rather than to the group Stage III/IV (Q3=3.58 ng/ml). Using the plasma TGF-beta(1) concentration of 3.00 ng/ml as the cut-off value, two subgroups of patients were formed. Overall 2-year survival of the first subgroup, having elevated plasma TGF-beta(1) ( GT 3.00 ng/ml; n=10), was 10%. This was significantly decreased (p LT 0.05) compared to 52% survival observed for the second subgroup of patients with plasma TGF beta(1) values close to HD ( LT 3.00 ng/ml, n=19). Conclusion: We have performed a pilot study to determine the relationship between overall survival and TGF-beta(1) concentration in the blood of metastatic breast cancer patients. The survival was significantly reduced in the patients with elevated plasma TGF-beta(1) levels compared to that of the patients with plasma TGF-beta(1) levels close to normal. We propose that plasma TGF-beta(1) concentration may be a new tumour marker attributed to the presence of metastatic BC cells that may be used in selection of metastatic BC patients with poor prognosis.
