Background: The clinical significance of thecirculating levels of activin A and matrix metalloproteinase-2(MMP-2) and -9 (MMP-9) was investigated in patients withbreast cancer (BC) or prostate cancer (PC) with (M1) orwithout (M0) bone metastasis. Patients and Methods: MMP-2,MMP-9 and activin A blood concentrations were measured byenzyme immunoassays in 79 cancer patients and in 57 healthyblood donors (HS) who served as a control group. Thediagnostic accuracy of these molecules to discriminate betweenM0 and M1 patients was evaluated by the receiver operatingcharacteristic curve (ROC) and compared to that of tumormarkers CA15.3 or prostate-specific antigen (PSA). Results:Activin A and MMP-2 were significantly increased in BC andPC patients as compared to sex-matched HS while MMP-9levels were more elevated only in the PC patients. Interestingly,in the PC patients, activin A levels were significantly higher thanthose measured in the BC patients. In this latter group, activin Aand CA15.3 but not MMP-2 or MMP-9 were increased in theM1 patients as compared to M0 patients. Furthermore, asignificant relationship was also highlighted between activin Aconcentration and the number of bone metastases and tumorgrade, between MMP-9 and tumor grade, and between MMP-2and CA15.3. ROC curve analysis showed a good diagnosticaccuracy for activin A and CA15.3 but a poor accuracy forMMP-2 and MMP-9 in discriminating between M0 and M1patients. However, CA15.3 retained the best diagnostic accuracyin this respect. In the PC group, only activin A and PSA levelswere significantly increased in the M1 patients as compared tothe M0 patients. A similar although not statistically significanttrend was noted for MMP-9. Interestingly, a significant correlationwas observed between PSA and activin A and MMP-9, andbetween Activin A and Gleason score and the number ofskeletal metastases. ROC curve analysis showed a gooddiagnostic accuracy for activin A, MMP-9 and PSA and a poordiagnostic accuracy for MMP-2 in detecting M1 patients.However, PSA showed the highest diagnostic accuracy.Conclusion: Activin A, MMP-2 and MMP-9 may be regarded aspossible therapeutic targets in the treatment of metastatic bonedisease. However, their usefulness as additional markers of bonemetastasis remains to be better defined
