- Estrogen receptor, progesterone receptor and HER-2 status were derived from the gene array data. Cutpoints were 8.2 for the estrogen receptor, 10.2 for HER-2, and 4.5 for the progesterone receptor. Log2 transformed gene array data have been used.
-
1The hormone receptor status is positive when either the estrogen or progesterone receptor RNA expression is high.
