Who can take part

AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for men with high-risk prostate cancer whose PSMA-PET scan shows no spread, and who are planned for surgery to remove the prostate.

Age
18 years or older, with a life expectancy of more than 15 years.
Sex
Men only.
Disease stage
High-risk prostate cancer: biopsy-proven WHO/ISUP grade group III-V, or grade group II with PSA above 20 ng/ml. The PSMA-PET scan must show no spread to nearby or distant sites.
Earlier treatment
No earlier treatment for prostate cancer, no earlier pelvic lymph node removal and no earlier pelvic radiotherapy.
Biomarker or test result
PSMA-PET scan negative for regional and distant spread.

Main reasons for not taking part

  • Grade group I cancer with cT1 or cT2 on MRI
  • cT4 cancer on MRI
  • Positive PSMA-PET for local or distant spread
  • Any earlier treatment for prostate cancer
  • Earlier pelvic lymph node removal or pelvic radiotherapy

Who can take part

  • Age ≥ 18 years and life expectancy >15 years
  • Any biopsy-proven WHO/ISUP grade groups III-V PCa
  • High-risk prostate cancer defined as:; Any biopsy-proven WHO/ISUP grade group III-V PCa or; ISUP grade group II and PSA > 20 ng/ml
  • PSMA-PET: negative staging for regional and distant metastasis
  • multidisciplinary tumorboard recommendation for radical prostatectomy
  • WHO performance status 0-1
  • Adequate condition (ASA ≤ III) for general anesthesia and RP

Who cannot take part

  • Any prior neoadjuvant, local or systemic treatment for PCa
  • Previous PLND or pelvic radiotherapy
  • Patients with a prior malignancy and treated with curative intention are eligible if all treatment of that malignancy was completed at least 2 years before registration and the patient has no evidence of disease at registration. Less than 2 years is acceptable for malignancies with low risk of recurrence and/or no late recurrence
  • Any other serious underlying medical, psychiatric, psychological, familial, or geographical
  • condition, which in the judgment of the investigator may interfere with the planned
  • ISUP grade group I PCa and cT1 or cT2 (MRI)
  • cT4 (MRI) PCa
  • PSMA-PET: positive staging for local and distant metastasis
  • staging, treatment and follow-up, which affect patient compliance or place the patient at
  • high risk from treatment-related complications
  • Vulnerable men (participants incapable of judgment or participants under tutelage) will not be included in the study

About the trial

What the trial wants to find out

The aim of the DISSECTION 2.0 study is to determine whether extended pelvic lymph node dissection (ePLND) provides a therapeutic benefit for high-risk prostate cancer patients by improving cancer staging and potentially removing micrometastatic disease, ultimately improving their outcomes.

The 2 groups in the trial

  • Radical prostatectomy with extended pelvic lymph node dissectionTreatment being tested

    Treatment: Extended Pelvic Lymph Node Dissection

  • Radical prostatectomy without extended pelvic lymph node dissectionNo study treatment, for comparison

Questions to ask the study team

  1. How often do I need to come in, and for how long each time?
  2. Are travel costs paid?
  3. Can I keep my own doctor?
  4. What happens if I want to stop?
