The purpose of this study is to see what effects, good and/or bad, proton based radiation combined with low dose chemotherapy and hormonal therapy, has on patients and their cancer.

Condition Intervention
Prostate Cancer
Radiation: < 15% risk of + LN
Radiation: > 15% risk of + LN

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: No masking
Primary Purpose: Treatment
Official Title: A Phase II Study of Proton-Based Radiation Therapy With Elective Pelvic Nodal Irradiation, Concomitant Docetaxel, and Adjuvant Androgen Deprivation for High-Risk Prostate Adenocarcinoma

Further study details as provided by University of Florida:

Primary Outcome Measures:
  • Acute Grade 3 or Higher Treatment-related Toxicity Rate. [ Time Frame: 6 months after the completion of radiation therapy ]
    Number of participants that experienced acute grade 3 or higher, treatment-related toxicity based on CTCAE version 3.0 criteria.

Secondary Outcome Measures:
  • Collect and Analyze Quality of Life, Treatment-related Late Morbidity, Disease Control, and Survival Outcome Parameters. [ Time Frame: After radiation: every 6 months for 3 years, then annually for 20 years ]
  • Collect and Analyze Treatment, Biologic and Diagnostic Information That May Impact Quality of Life, Disease Control, Morbidity and/or Survival Outcomes. [ Time Frame: After radiation: every 6 months for 3 years, then annually for 20 years ]

Enrollment: 77
Study Start Date: December 2009
Estimated Study Completion Date: January 2035
Primary Completion Date: January 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: High-risk arm A (HR-A)
< 15% risk of + lymph nodes (LN)
Radiation: < 15% risk of + LN
Total of 54 Cobalt gray equivalent (CGE) over 30 treatments to prostate + seminal vesicles (SV), then proton boost total of 23.4-27 CGE over 13-15 treatments to prostate +/- SV. Low dose docetaxel every week during radiation therapy (RT) followed by androgen deprivation therapy for 6 months.
Experimental: HR-B
> 15% risk of + LN
Radiation: > 15% risk of + LN
Total of 45 Gy over 25 treatments to prostate + SV + LN, then proton boost total of 32.4-36 CGE over 18-20 treatments to prostate + SV. Low dose docetaxel every week during RT followed by androgen deprivation therapy for 6 months.


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   No

Inclusion Criteria:

* Adenocarcinoma of the prostate.

Exclusion Criteria:

  • Previous prostate cancer treatment such as chemotherapy and/or pelvic radiation.
  • Active inflammatory bowel disease (diverticulitis, Crohn's disease or ulcerative colitis) affecting the rectum. (Non-active diverticulitis and Crohn's disease not affecting the rectum are allowed.)
  • History of hip replacement.
  • Prior intrapelvic surgery. This includes the following:
  • Transrectal or rectal surgery other than polypectomy or hemorrhoid removal or banding
  • Transabdominal pelvic surgery
  • Bladder surgery
  • Prior myocardial infarction (MI) or congestive heart failure (CHF).
  • Taking Saw Palmetto or methotrexate and unable or unwilling to discontinue its use during radiation.
