I actually had quad therapy since they added the Carboplatin. I am now a few months past that. My post scans still showed the spots but they were smaller. He was unsure whether it was still active cancer or just the so called scar tissue of dead cancer cells. We could have just stopped and waited for another scan in a few months to see or hit it with a 5th. medication. He recommended the latter and gave me the choice and I chose to continue with the Pluvicto. I have completed 2 of the 6 doses. They will do a scan immediately prior to the 4th.dose then based on that scan we’ll decide whether to proceed with 5 and 6. If the scans show the cancer is gone or if it shows the Pluvicto is not working then I’ll probably not receive the 5th and 6th doses.
