title: [Tumour markers in human breast cyst fluid in gross cystic breast disease (GCBD)]
abstract: AIM: Parallel measurements of tumour markers in the serum and breast cyst fluid in a high risk group (GCBD) of breast cancer. The identification of individuals belonging to this group and their follow-up. MATERIALS AND METHODS: In the breast cyst fluid of 108 patients with GCBD (mean age 47 years) we measured the levels of CA 15-3, TPA, CEA and beta HCG completed by PCT determinations. Simultaneously, the serum CA 15-3 and TPA concentrations were also measured using the Luminescent Immunoassay techniques. RESULTS: Strikingly high TPA values were found in 98% of the patients. The CA 15-3 levels, however, were pathological only in 24%of them. The CEA and beta HCG levels showed hardly any rise and the PCT concentration remained normal. CONCLUSIONS: The lack of any rise in PCT concentration precludes the inflammatory origin of the cystic fluid and the normal serum arker levels exclude ultrafiltration. The increased TPA concentration in the breast cystic fluid and the occurrence of pathological CA 15-3 level in the above percentage of the cases suggest that GCBD represents not only a high risk group but possibly a precancerous state, too.
