Estrogen receptor studies in breast cancer based on histological material. Correlation with results from needle biopsy aspirates and pS2 protein determination

摘要: Oestrogen receptor analyzed in archive, histologic specimens from 57 breast cancers showed a concordance with determination fresh material of 50 to 60%. This means that about half the oestrogen positive tumours are "lost" when using specimens. pS2 protein is an indirect marker functioning and was demonstrated 84% carcinomas, including 15 were cytologic material, but negative In cases where only available for analysis, additional may be useful.
