    Abstract:
    A total of 93 breast cyst fluids (BCF) obtained by needle aspiration of women suffering from gross cystic mastopathy was hormonally investigated. The mean age of the patients was 45 years (range 27-65). Estradiol (E2), progesterone (PROG), testosterone (TE), prolactin (PROL), estriol (E3), dehydroisoandrosterone and its sulfate (DHA, DHA-S) levels were investigated in the BCF and in the respective sera. Tumour marker beta-HCG and CA 15-3 as well as cations (K+, Na+) were determined, too. E2, E3, PROG, TE, PROL, DHA, DHA-S and K+ showed significant accumulation in the BCF compared to the serum values. The K+/Na+ ratio proved to be a useful tool to divide cysts into type I (> or = 1), type II (< 1 but > or = 0.1) and type III (< 0.1) subgroups. In case of type I BCF, higher E2, DHA, DHA-S and PROL levels could be detected, while PROG and TE contents proved to be the highest in type II cysts. These findings indicate that the type I BCF is a marker for "active" GCD of the breast and suggest that it may be associated with increased breast cancer risk. It is suggested therefore when macrocysts are aspirated, sex steroids, steroid hormone precursors and cations in the BCF should be examined routinely, and women with type I cysts should be controlled carefully.
