Session

The changing landscape in the management of prostate cancer recurrence

Thematic Session 03

  • Location:
    Room Stockholm (Hall B2, level 0)
  • Chair:
     A. De La Taille, Créteil (FR)
  • Aims and objectives of this session

    The approach to recurrent prostate cancer (PCa) after curative treatment has dramatically changed over the recent years due to significant advances in imaging technologies and a better understanding of disease biology. This has opened new horizons in the context of administration of individualised treatments which include systemic and metastasis-directed therapies. The aim of this session is to update the biology knowledge of PCa recurrence and to assess the optimal use of individualised imaging and therapeutic approaches for recurrent disease.

State-of-the-art lecture The genomic picture of recurrent prostate cancer
 G.S. Bova, Tampere (FI)
Aims and objectives of this presentation

• Review current knowledge and recent advances in the genomics of metastatic prostate cancer

Early experience of robotic salvage pelvic lymph node dissection in the Ga-68 PSMA PET scanning era

By: Murphy D.1, Zargar H.1, Van Den Bergh R.1, Van Bruwaene S.1, Goad J.1, Coughlin G.2, Harewood L.3, Dundee P.3

Institutes: 1Peter Mac Callum Cancer Institute, Dept. of Cancer Surgery, Melbourne, Australia, 2Wesley Hospital, Dept. of Urology, Brisbane, Australia, 3Epworth Hospital, Dept. of Urology, Melbourne, Australia

Aims and objectives of this presentation

68Ga-PSMA PET/CT has recently been introduced and shows much promise for the assessment of recurrence following radical prostatectomy. Our aim was to assess the utility of salvage pelvic lymph node dissection in men with biochemical recurrence after radical prostatectomy selected by 68Ga-PSMA PET/CT.

Aims and objectives of this presentation

Although prostate cancer is often multifocal, the clonal origin of multifocal disease is controversial. In addition, it is currently unknown what characterizes the biologically dominant nodule. The objective of this presentation to showcase our data which demonstrate i) that different foci of prostate cancer exhibit molecular heterogeneity suggesting independent clonal origin; and ii) that a biologically dominant nodule possesses the capability to metastasize to lymph node (s).

Aims and objectives of this presentation

To determine the therapeutic impact of postoperative radiation in the adjuvant and salvage settings after controlling for both genomic and clinico-pathologic risk

Aims and objectives of this presentation

Intermittent androgen deprivation mono therapy is evaluated in 918 patients with M1 and local advance prostate cancer with a median follow up 5.5 years. Metastatic status PSA and age are all prognostic factores for survival. + 75 years and PSA that falls to 2-4 at randomization have an increase hazard of dying 1.63 ,1.95 , 2.01.
The inicial results shoed no survival diference,but now there is a poor survival in continuos therapy than intermittent principally associated with an excess CDV deaths 119 int 137 cont and the same prostate deaths 96.
