Learning issue: Prostate cancer metastases-MH Metastatic prostate cancer: Prostate cancer typically spreads long the obturator, internal/external/common iliac and prescaral lymph node chain. Because the average size of positive lymph nodes at dissection is 7mm, standard size criteria are not sensitive for early lymph node involvement. Bone metastases likely occurs through hematogenous spread of cancer cells from the periprostatic veins lateral to the prostate, to the internal iliac veins, to the presacral venous plexus, to the veins of the spine. Prostate cancer causes predominantly osteoblastic metastases to the axial skeleton, which are

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
