Hypofractionated Radiation Therapy for Treating Prostate Cancer High-Risk Features Following Radical Prostatectomy

A Phase II Trial of Hypofractionated Radiation Therapy for Prostate Cancer With High Risk Features After Radical Prostatectomy

Source: ClinicalTrials.gov · Last updated 26 May 2026

Brief summary (registry, in English)

This phase II trial studies how well hypofractionated radiation therapy works in treating participants with prostate cancer high-risk features following radical prostatectomy. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects.

Who cannot take part

Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.

Prior treatment

  • Previous pelvic radiation
  • Prior androgen suppression therapy for prostate cancer for more than 6 months
  • Prior systemic chemotherapy for prostate cancer
  • Evidence of any other cancer within the past 5 years and \< 50% probability of a 5 year survival. (Prior or concurrent diagnosis of basal cell or non-invasive squamous cell cancer of the skin is allowed)

Other illness

  • Active rectal diverticulitis, Crohn's disease affecting the rectum or ulcerative colitis (non-active diverticulitis and Crohn's disease not affecting the rectum are allowed)
  • History of proximal urethral stricture requiring dilatation
  • Major medical, addictive or psychiatric illness which in the investigator's opinion, will prevent the consent process, completion of the treatment and/or interfere with follow-up. (Consent by legal authorized representative is not permitted for this study)
  • History of myocardial infarction or decompensated congestive heart failure (CHF) within the last 6 months

Lab values

  • Current and continuing anticoagulation with warfarin sodium (coumadin), heparin, low- molecular weight heparin, Clopidogrel bisulfate (plavix), or equivalent (unless it can be stopped to manage treatment related toxicity, to have a biopsy if needed, or place markers)

Who the study is looking for

  • Histologically confirmed prostate adenocarcinoma at the time of surgery
  • Pathologic stages T2-T3b, N0-Nx-N1, M0-1 as staged by the pathology report (American Joint Committee on Cancer \[AJCC\] criteria 8th edition \[Ed.\])
  • One or more high risk features including: seminal vesicle invasion, extracapsular extension, positive margins, or a PSA post surgery between 0.2 and \< 2.0
  • PSA values \< 2 ng/ml within 90 days prior to enrollment. Obtained at least 6 weeks after surgery
  • Eastern Cooperative Oncology Group (ECOG) performance status 0-2 assessed within 90 days of enrollment
  • Patients must sign Institutional Review Board (IRB) approved study specific informed consent
  • Patients must complete all required pre-entry tests within the specified time frames
  • Patients must be able to start treatment (androgen suppression \[AS\] or radiation) within 120 days of study registration
  • Members of all races and ethnic groups are eligible for this trial
  • Patients from outside of the United States may participate in the study
