Poster Session 36

  • Location:
    Room Stockholm, North Hall (Level 1)
  • Chairs:
     I.T.R. Cavarretta, Milan (IT)
     C. Jeronimo, Porto (PT)
     H.G. Lilja, New York (US)
  • Aims and objectives of this session

    Use of validated prostate cancer biomarkers is important for selection of patients who risk developing aggressive disease and also for monitoring castration therapy resistance. Novel approaches to analyze markers in multifocal prostate cancer will be presented.

  • Poster viewing of 20 minutes. Presentations will take place on stage. Standard presentations are 2 minutes in length, followed by 2 minutes for discussion. Extended presentations (*) are 3 minutes in length, followed by 3 minutes for discussion.
