Tumor Response Can be Identified by Imaging Progesterone Receptor

Study posted in the July issue of The Journal of Nuclear Medicine indicates imaging progesterone receptor (PR) condition also are able to determine responders and non-responders to endocrine therapy at an earlier stage. Estrogen receptor-α (ERα) status is a vital factor in identifying the foremost appropriate treatment for breast cancer affected individuals, especially for individuals who are ERα+ and likely to answer well to hormone-based, or endocrine, therapy.

The research, "Small-Animal PET of Steroid Hormone Receptors Expects Tumor Reaction to Endocrine Session Utilizing a Preclinical Version of Breast Cancer" appeared to be an example of his exclusive method of study.

"Positron release tomography, or PET, has generally been used to know about the target for endocrine session in breast cancer by showing that ER exists in tumors using F-18-fluoroestradiol (FES)-PET, or by checking for hormone-induced changes in tumor metabolism-'metabolic flare'- along with F-18-fluorodeoxyglucose (FDG)-PET once therapy has begun.

What exactly is novel about our study may be that we selected to image progesterone receptor stages to discover how the estrogen signaling trail is operating for an endocrine therapy," said Amy Fowler, MD, PhD, lead writer of the study.
