The purpose of this study is the identification and classification of human tissues and cytology specimens and elements therein.

Computer aided technology to assist the pathologists to identify, quantify, characterize and report their findings with regards to one or more diagnoses they should perform. In particular and for example: the scoring of the number of elements and their protein (antibody) expression level within a paraffin embedded tissue section.

Biospecimen Retention:   Samples Without DNA

Paraffin embedded tissue sections of the breast

Enrollment: 150
Study Start Date: May 2006

Ages Eligible for Study:   20 Years and older
Genders Eligible for Study:   Female
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population

The breast samples were taken from female patients after tru cut biopsies, lumpectomies or mastectomies. Paraffin embedded blocks were prepared from the specimens out of which sections were stained immunohistochemically with the Vision Bio Systems mouse monoclonal antibodies for Estrogen Receptor (NCL-ER-6F11) and Progesterone Receptor (NCL-PGR-312). All stages were performed under the routine procedure of the hospital laboratory.


Inclusion Criteria:

  • Well stained paraffin embedded tissue specimens

Exclusion Criteria:

  • Fade away slides
