Well, next week, I'll be getting my 4th and final lutathera-prrt retreatment. I'm also combining Keytruda as well. I had my initial 4 treatments back in 2023 I think. Generally, I take some anti- nausea meds for about 10 days after to ensure no nausea. I also drink lots of coffee/water/fluids after prrt as well since I don't want to kill my kidneys. I believe the major risks of lutathera are mylosuppression and or leukemia. These usually present themselves about 2 years after treatment. I'm not sure what the increased risks for the retreatments are since the RETREAT study ain't done. Wait and see, I guess. It's criminal that this treatment costs $750k in us but only $55k euros in europe.
