A 53-year-old waitress inquiries about the implications of positive estrogen receptors (ER+) in an invasive carcinoma that is excised from her left breast.She should be informed of what?
ER and PR status should be determined in all cases of breast carcinoma. Positive ER and PR are indicative of an improved outlook and likelihood of response with antiestrogen medication. PR+ do not predict negative ER status.
