Paul Edwards Posted March 24, 2015 Share Posted March 24, 2015 Xofigo (radium 223) has changed the treatment of prostate cancer metastatic to bone. Xofigo is chemically similar to calcium, so tissues that uptake calcium uptake radium as well. That means principally bone, especially in highly metabolically active sites like bone metastases. Lutetium-177 (Lu-177) is a radioactive substance which scientists have attached to an antibody found on the surface of at least 95 percent of prostate cancer cells and called prostate surface membrane antigen (PSMA). Unlike Xofigo, which only attaches to bone metastases, Lu-177-anti-PSMA attaches to any metastasis — bone, lymph node or visceral. It can potentially treat systemic micrometastases as well.
