Prostate cancer isotope treatment with 177Lu-PSMA or RLT

One of the most common treatments for cancer is external beam radiation therapy. It is possible to deliver radiation directly to the tumour using radioactive isotopes that are administered either orally or by injection.

177Lu-PSMA therapy allows the simultaneous treatment of the tumour and its metastases, regardless of location. Radioisotope therapy is repeated 4 or more times at 6-8-week intervals. Before 177Lu-PSMA therapy, several blood tests and examinations must be performed, which will be prescribed by your doctor. Before coming to the hospital on the day of your treatment, eat a normal breakfast and drink plenty of water (about one litre in addition to your usual volume).

You will be admitted to the hospital for at least one night. During this time, several images are taken of your body with a gamma camera to assess the distribution of 177Lu-PSMA in your body.

After the end of the therapy, you can leave the hospital and continue as normal. Over the next 2-3 days, it is important to drink plenty of fluids (2-3 litres per day) to protect the kidneys and allow the remaining radioactive substance to be cleared faster from the body. When you leave the hospital, the staff will give you written instructions on how to safely interact with others after radiation therapy.
