AB  - We examined the association between an elevated plasma TGF-beta(1) level and the disease progression of advanced breast cancer (BC) patients (n = 44). TGF-beta(1) levels were detected by an enzyme-linked immunosorbent assay (ELISA). Platelet carryover and in vitro platelet activation in our plasma samples was assessed and found to be insignificant. Plasma TGF-beta(1) values were significantly elevated (P LT 0.05) in stage IIIB/IV patients (median value: 2.40 ng/ml, range: 0.13-8.48 ng/ml, n=44) compared with healthy donors (median value: 1.30 ng/ml, range: 0.41-4.93 ng/ml, n=36). Although pronounced in metastatic patients, especially those who had been newly diagnosed, TGF- and beta;(1) elevation was independent of tumour mass, site of distant metastases, histopathological type, steroid receptor (SR) content and age of the BC patients. Follow-up of 6 patients indicated a relationship between the plasma TGF- and beta;(1) and the patients response. This suggests that TGF- and beta;(1), may be a promising prognostic marker for breast cancer patients with advanced disease. Confirmatory large-scale studies are needed, particularly given the overlap of values between our different subgroups analysed.

AB  - There has been much controversy concerning the detection of plasma TGF-beta (1) levels in breast cancer patients. The present study provides preliminary evidence on underestimated plasma TGF-beta (1) levels due to ex vivo proteolysis and previous therapeutic treatment of breast cancer patients, as detected by a commercial ELISA immunoassay. Our results revealed that the addition of protease inhibitors: phenylmethylsulfonyl fluoride and aprotinin, to the plasma preparation of healthy volunteers, has increased TGF-beta (1) median Value from 3.1 ng/mL to 33.9 ng/mL. Relative to that, in protease-inhibited plasma of locally advanced/metastatic breast cancer patients, significantly elevated TGF-beta (1) was observed (median value: 65.5 ng/mL), which included untreated and previously treated patients with median values of: 74.2 ng/mL and 58.1 ng/mL, respectively. These findings indicate to the potential usefulness of this plasma marker in breast cancer prognosis, thus deserving future clinical attention.
