At day 0 before start with bicalutamide, a FDHT-PET/CT will be performed, and one after 6 weeks (i.e. 2 weeks after steady-state). The second FDHT-PET will be performed to determine if this scan can be used as a biomarker for early response. Patients will be treated with bicalutamide until progression or unacceptable toxicity is encountered.
Other Name: casodex
Procedure: FDHT PET
Other Name: 18F-FDHT PET
- quantify residual AR binding sites in metastatic breast cancer [ Time Frame: 6 weeks ]To quantify residual AR binding sites in metastatic breast cancer after 6 weeks of treatment with bicalutamide.
- determine whether changes in 18F-FDHT uptake [ Time Frame: 6 weeks ]To determine whether changes in 18F-FDHT uptake after 6 weeks associates with response to bicalutamide.
- Influence amount of AR tumor expression [ Time Frame: 6 weeks ]To determine whether 18F-FDHT tracer uptake is influenced by the amount of AR tumor expression.
- Difference in changes in AR availability [ Time Frame: 6 weeks ]To determine whether changes in AR availability are different for breast cancer subgroups during treatment with bicalutamide
