3 targeted therpies for prostate cx
1-samarium 153 (quadramet)
2-strontium-89 (metastron)
3-radium-223 (xofigo)
which therpay is used for palliative care for bnoe pain due to prtosate metsq
sm 153 and sr 89
which therpay treats castrate resistant prsoate cx that has mets bone
ra 223
when is sm 153 not okay
danger of spinal cord compression or pathlogic fx in extremities expected (instead surgery or local XRT)
energy and half life of sm 153
beta=0.81 Mev gamma= 103 keV and 1.9 d

does a pure beta emitter need assaying prior to admin
nocan
can sm 153 edtmp be imaged
yes bc gamma
xofigo dose is
