My husband has been on Zytiga, Lynparza as well as Keytruda all which have failed. He is now on Docetaxel he had his fourth round today. Psa does not seem to be responding. He will have bone scans and ct scan.Is there something he can take in conjunction with the chemo? If this treatment fails I don’t know where to go from here. Could any of you maybe share a similar story and what would be next as a possible treatment. Feel so defeated and petrified. Thank you so much
