Brief Summary:
Following a radical prostatectomy and lymph node sampling, eligible patients will undergo post-operative radiation therapy, concurrent weekly docetaxel chemotherapy , and hormonal therapy (Casodex daily and Zoladex every 3 months for 2 times or Lupron 22.5 mg im every 3 months for 2 times).

Condition or disease Intervention/treatment Phase
Prostate Cancer Drug: Docetaxel Radiation: Radiation Therapy Drug: Casodex and Zoladex (or Lupron) Phase 1 Phase 2

Detailed Description:

After consent, laboratory and radiologic tests will be done and a baseline questionnaire will be completed. Participants will then be started on the protocol specific hormonal therapy for a total of 6 months. After 2 months of hormone therapy the participants will begin radiation therapy and concurrent docetaxel chemotherapy treatments.

The radiation therapy will be delivered to a total dose of 66.0 Gy at 2.0 Gy/fraction (fx) once daily over 7 weeks, using either a 3-D conformal technique and/or intensity modulated radiation therapy (IMRT).

Participants will receive docetaxel once a week for a total of 7 infusions with concurrent radiation therapy treatments. The weekly dose of docetaxel will be 20 mg/m2. Docetaxel will be given as an intravenous (IV) infusion over 30 minutes within ≤6 hours prior to the radiotherapy treatments.

Layout table for eligibility information
Ages Eligible for Study:   18 Years to 85 Years   (Adult, Older Adult)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Only those patients with adenocarcinoma of the prostate who have undergone a radical prostatectomy with pelvic lymph node sampling and found to have high risk non-metastatic disease with undetectable, persistent or decreasing post-operative Prostate Specific Antigen (PSA) levels, or who have subsequently experienced a rise in PSA, will be eligible for the trial as described below in the inclusion and exclusion criteria
  • Histologically documented adenocarcinoma of the prostate.
  • Status post radical prostatectomy with sampling of the pelvic lymph nodes with histologically confirmed adenocarcinoma of the prostate, with the patients falling into either the "adjuvant high risk group" or the "salvage high risk group" as follows:

    • a) "Adjuvant High Risk Group" (undetectable, persistent or decreasing PSA levels before starting therapy) who have NO evidence of metastatic disease (i.e. no clinical symptoms or radiologic evidence) who MUST be able to start RT treatments within 6 months of radical prostatectomy with at least one of the 3 disease features:

      1. Pathologic tumor 2-node 0 (T2N0) disease with positive margins and Gleason score ≥8, or
      2. Pathologic tumor 3a-node 0 T3aN0 disease with extracapsular extension and Gleason Score ≥ 8, or
      3. Pathologic tumor 3b-node 0 T3bN0 disease with any Gleason Score
    • b) "Salvage High Risk Group" are those patients with PSA biochemical failure defined by 2 consecutive increases over baseline PSA levels at least one month apart, who have NO other evidence of metastatic disease (i.e. no clinical symptoms or radiologic evidence), and WITH AT LEAST ONE of the high risk disease features as defined below:

      1. Pathologic T3bN0 disease with any Gleason score, or
      2. Pathologic T2-3aN0 disease with Gleason score ≥ 8,
      3. Pathologic T2-3aN0 disease with PSA doubling time ≤10 months, or
      4. Pathologic T2-3aN0 disease with Pre-radiation therapy PSA level ≥1.0 ng/ml
  • Neoadjuvant hormonal therapy prior to radical prostatectomy is allowed, and post-prostatectomy hormonal therapy is allowed as long as it is not within 6 months of protocol treatment
  • No prior chemotherapy, or pelvic irradiation
  • Karnofsky Performance Status ≥70
