is Lu177
- PSMA
treatment
and where it is used?
Lutetium-177
PSMA (Prostate-Specific
Membrane Antigen Therapy)
therapy uses a molecule (tracer) that attaches to the PSMA receptors on
cancer cell surface. Before it is administered, the tracer is bound
with Lutetium-177, which emits beta radiation - a destructive type of
radiation that kills cancer cells when when it binds to cell surface.
In many patients, the treatment has proven to be a successful way to reduce the size of the tumours. Men who have undergone radical prostatectomy or primary radiotherapy but show symptoms of metastatic recurrence may find Lutetium-177 PSMA Therapy a viable treatment option with minimal side effects.
Lu177- PSMA therapy is used to treat prostate cancer only.
