Steve55777's posts here ~~~ detailing his treatment S-U-C-C-E-S-S with Lutetium-177 ~~~ have been tremendous.
Even better, his doctors have stated that additional treatments are certainly possible, down the road, if needed.
I found this brief descript
ion in a recent newsletter sent to me by the Prostate Cancer Foundation.
I especially focused on the detailed descript
ion of how prostate cancer cells are TARGETED and literally KILLED. Yes, targeted & killed!
I felt it helped me better understand these new treatments:
"TITLE: Breaking NEWS --- First-In-Class Therapy Approved For Advanced Prostate Cancer:
Lutetium- PSMA - 617 (LU- PSMA) is now FDA-approved for metastatic castrate-resistant prostate cancer patients who have received certain other treatments (androgen receptor pathway targeting agents & taxane-based chemotherapy).
Patients must also have a positive PSMA PET scan.
This represents a PARADIGM SHIFT in the treatment of advanced prostate cancer, and is HOPEFUL news for patients who have seen their disease progress, on other therapies.
LU-PSMA works to deliver a small amount of RADIATION to prostate cancer cells, anywhere in the body.
One part of the LU-PSMA molecule RECOGNIZES & BINDS to its target, called PSMA (prostate-cancer specific antigen).
PSMA is a protein that is present on nearly all prostate cancer cells, but NOT on most normal tissue.
This PSMA-seeking 'arrow' is chemically linked to a radioactive 'PAYLOAD' called LUTETIUM-177.
When LU-PSMA binds to the prostate cancer cells, the cell takes up the radioactive drug and is KILLED.
The radiation from LUTETIUM-177 travels only a short distance outside the target cell, so the surrounding normal tissue is largely spared."
My best to each & all ~~~
