    It’s obvious why only three of the 10 men who participated in the clinical trial responded to treatment with Keytruda. The drug requires two conditions: Adequate expression of PD-L1, and an opportunity for the T-cells to be activated. Presuming the first condition was met, for the T-Cells to be activated, cancer cells must be present in either the lymphs or the spleen. If the cancer cells are missing from these locations (or are quickly eliminated through action of the Keytruda), then no T-cell activation will occur.

      Would like to know who Jim Davidson is and where the information Jim provides comes from. Does it make sense, Im a cancer patient with both multiple myeloma and advanced prostate cancer whis is in good health except for the cancer problems after 7 years of various active treatment. Also how is PD-L1 testing done and who does it? Thanks for you interest in my post. Mike

        Mike Branam would love to talk to you. My husband Also has multiple myeloma and advanced prostate cancer, he’s 47. There must be a link between these two diseases and perhaps the link could help lead to better treatment.

    My husband has stage four prostate cancer and is towards the end of the medicines. Where can I get further information regarding treatment with Keytruda.

      Please keep checking.

    Anyone doing clinical trials for keytruda where the patient is on Lupron and has already had taxatere with no positive response – actually has increased metastatic tumor growth? PSA remains (has always been)low.
