SBRT Versus Hypofractionated Radiotherapy for Biochemically Recurrent or Oligometastatic Prostate Adenocarcinoma

Description

This phase III trial tests the side effects of stereotactic body radiation therapy (SBRT) compared to hypofractionated radiotherapy for treating patients with prostate adenocarcinoma that has come back after a period of improvement (recurrent) or that has spread from where it first started (primary site) to a limited number of sites (oligometastatic). SBRT is a type of external radiation therapy that uses special equipment to position a patient and precisely deliver radiation to tumors in the body (except the brain). The total dose of radiation is divided into smaller doses given over several days. This type of radiation therapy helps spare normal tissue. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumors cells and have fewer side effects. SBRT may work just as well as hypofractionated radiation therapy at treating patients with biochemically recurrent or oligometastatic prostate cancer, but with a shorter treatment time and possibly fewer side effects.

Conditions

Biochemically Recurrent Prostate Carcinoma, Oligometastatic Prostate Carcinoma, Recurrent Prostate Adenocarcinoma, Stage IIB Prostate Cancer AJCC v8, Stage IIC Prostate Cancer AJCC v8, Stage III Prostate Cancer AJCC v8, Stage IV Prostate Cancer AJCC v8

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • * Histologically confirmed prostate adenocarcinoma at the time of surgery
  • * Pathologic stages T2-T3b, Nx or N0-1, M0-1 as staged by the pathology report (American Joint Committee on Cancer \[AJCC\] Criteria 8th edition \[Ed.\])
  • * PSA post radical prostatectomy ≥ 0.1 and \< 2.0 ng/mL ≤ 90 days prior to enrollment, obtained ≥ 6 weeks after surgery
  • * Eastern Cooperative Oncology Group (ECOG) performance status 0, 1, or 2 assessed ≤ 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 (ADT or radiation) ≤ 120 days of study registration
  • * Patients must be ≥ 18 years old
  • * Prostate cancer up to oligometastatic disease, up to 5 sites
  • * Previous pelvic radiation
  • * Prior androgen deprivation therapy for prostate cancer and PSA ≥ 0.1 ng/mL
  • * 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)
  • * Prior systemic chemotherapy for prostate cancer
  • * 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
  • * On a transplant list
  • * More than oligometastatic disease \> 5 metastatic sites
