fibrinopeptide-b and Breast-Neoplasms

The predictive value for cancer recurrence of five measurements of haemostatic activity was studied in 89 patients with operable breast cancer. Neither preoperative nor sequential measurements up to 9 months postoperatively of fibrinopeptide A, fibrin fragment B beta 15-42, fibrinogen and serum fibrin(ogen) degradation products nor the fibrin plate lysis assay correlated with early recurrent disease. B beta 15-42 values were higher preoperatively in patients with oestrogen receptor positive tumours (P = 0.017). Mean B beta 15-42 values rose postoperatively (P = 0.003), largely because of an increase in patients with oestrogen receptor negative tumours.

Fibrin formation and fibrinolysis were estimated in 89 breast cancer patients by measurement in plasma of Fibrin Fragment B beta 15-42 and Fibrinopeptide A (FPA), serum Fibrin(ogen) Degradation Products (FDPs) and plasminogen activator by Fibrin Plate Lysis Assay. Results were compared with (a) 26 patients with benign breast diseases; and (b) 45 healthy factory workers. FPA, FDP and B beta 15-42 levels were elevated in both breast cancer patients and benign disease patients, but there were no significant differences between these two groups. Cancer stage, patient age and smoking habits did not affect these results, but Oestrogen Receptor (ER) positive patients had higher B beta 15-42 values than ER negative patients (p = 0.017). These results show that fibrin formation is enhanced preoperatively in patients with either benign or malignant breast disease. The fibrinolytic response to activated coagulation may be relatively deficient in breast cancer. The roles of malignancy, stress and other factors in the causation of these abnormalities require further assessment.
