PET scans 'confirm superiority of oestrogen-blocking breast cancer drugs'

Using PET scans, scientists have confirmed the effectiveness of using oestrogen-blocking drugs on breast cancer patients, some of whom will be using home care during their illness.

Research published online in Clinical Cancer Research used PET scans taken before, during and after hormonal therapy to confirm the superior effectiveness of oestrogen-receptor-blocking drugs such as tamoxifen and fulvestrant over oesterogen-depleting therapies.

The study also found that tamoxifen is superior to fulvestrant when it comes to blocking oestrogen.

Authors concluded: "This technology could be used early in drug development to measure effectiveness at the intended therapeutic targets, and to help refine selection and dosing for agents to move forward in drug development."

In other news, a new breast cancer drug known as GDC-0941, may successfully treat breast cancer, according to a paper presented at the 47th annual meeting of the American Society of Clinical Oncology.
