PURPOSE To determine if serum levels of the immunomodulatory protein, the progesterone induced blocking factor (PIBF), which is present in high levels during normal pregnancy, is present in higher levels in women with breast cancer positive for progesterone receptors. The study would also determine whether the presence or absence of the estrogen receptor in any way modifies PIBF expression. MATERIALS AND METHODS PIBF using a research ELISA was evaluated in the follicular phase in 21 women… Expand
