Estrogen and progesterone receptors in breast cancer: Comparison between enzyme immunoassay and computer-assisted image analysis of immunocytochemical assay

Untitled

“…With regard to primary tumors and local recurrences, concordance rates were in keeping with those of previous EIA-based studies (23)(24)(25). With regard to primary tumors and local recurrences, concordance rates were in keeping with those of previous EIA-based studies (23)(24)(25).…”

“…With regard to primary tumors and local recurrences, concordance rates were in keeping with those of previous EIA-based studies (23)(24)(25). Enzyme immunoassays rarely have been compared with IHC (23)(24)(25), and, to the authors' knowledge, only one study has compared EIA with IHC on paraffin sections for both ER and PR (25). The oldest IHC studies used frozen sections with ER-ICA and PgR-ICA, and concordance rates ranged from 77% to 91% for ER and from 72% to 74% for PR.…”

Hormone receptor status in breast cancer – a comparison between surgical specimens and fine needle aspiration biopsies

“…In this study, we found a concordance in defining receptor positivity between EIA in tumour homogenates and ICA in FNA biopsies of about 80%. This figure is in the same range as previously reported in comparative methodological studies based on small clinical materials 8,9,17,18 …”

The prognostic value of hormone receptor detection by enzyme immunoassay and immunohistochemistry: a prospective study in patients with early breast cancer

“…It has been suggested that ICA is a more specific and more sensitive test for the measurement of receptor content in breast cancer. 12 It is, however, impossible to draw conclusions concerning specificity and sensitivity and the discordant results in the present study. as they appeared to be constant over time and independent upon time-point of analysis.…”
