Cytoplasmic and nuclear estrogen and progesterone receptors in male breast cancer. 1982

R J Pegoraro, and D Nirmul, and S M Joubert

Cytoplasmic estrogen receptors were detected in 12 of 13 male breast cancer tumors. There was no significant correlation of receptor levels with the age of the patient, size and histological grading of the tumor, and stage and nodal involvement of the disease. Nuclear estrogen receptors were found in eight of 10 tumors and six of nine patients had tumors positive for cytoplasmic progesterone receptors, two of which were also found to contain nuclear progesterone receptors. The presence of cytoplasmic progesterone receptors, in addition to cytoplasmic and nuclear estrogen receptors, may be indicative of truly hormone-dependent tumors in male breast cancer. Treatment offered to patients included surgery, X-ray therapy, chemotherapy, and orchiectomy, but as yet, no general conclusions of the efficacy of the therapeutic regime can be drawn.

D011960	Receptors, Estrogen	Cytoplasmic proteins that bind estrogens and migrate to the nucleus where they regulate DNA transcription. Evaluation of the state of estrogen receptors in breast cancer patients has become clinically important.

D011980	Receptors, Progesterone	Specific proteins found in or on cells of progesterone target tissues that specifically combine with progesterone. The cytosol progesterone-receptor complex then associates with the nucleic acids to initiate protein synthesis. There are two kinds of progesterone receptors, A and B. Both are induced by estrogen and have short half-lives.

D002369	Castration	Surgical removal or artificial destruction of gonads.	Gonadectomy,Castrations,Gonadectomies
D002467	Cell Nucleus	Within a eukaryotic cell, a membrane-limited body which contains chromosomes and one or more nucleoli (CELL NUCLEOLUS). The nuclear membrane consists of a double unit-type membrane which is perforated by a number of pores; the outermost membrane is continuous with the ENDOPLASMIC RETICULUM. A cell may contain more than one nucleus. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed)	Cell Nuclei,Nuclei, Cell,Nucleus, Cell
