Evaluation of tumor and trophoblastic marker concentration in breast cyst fluid.
In our study we have examined 314 samples of cyst fluid taken from women suffering from fibrocystic breast disease (gross cystic disease). We have subdivided the cyst fluid with respect to epithelial coating and we have related trophoblastic protein content of the cyst fluid with age, seriousness of illness, and cytology of epithelial lining. We have performed RIA analysis of the trophoblastic proteins betahCG, beta1-SP-1, and alphahCG and in a smaller (n=84) group of specimens we have also tested for CEA, TPA, and ferritin. Trophoblastic proteins were positive in cystic fluids but the biological meaning of this is not known and the values are not related to clinical manifestations, except in a group of patients with apocrine metaplasia in which we tried to find a relationship between fertile age and increased betahCG. This finding presumably has a prognostic meaning that can be further understood by epidemiologic studies (of dietary intake and evaluation of lipid metabolites) and by information about inflammatory state of cystic fluid.
