I would not suggest someone have a prostate seed implant if they already had systemic disease. Assuming the metastatic disease is prostate cancer the patient would need more attention to the symptomatic mets.
Reply:Not really no, brachytherapy is very localised becaused it's treating the tumour from the inside so if it's already spread the radioactive seeds will have no effect on the mets because they will be too distant to recieve enough dose i'm afraid.
