About this trial

This is an interventional treatment trial for Prostate Cancer focused on measuring prostate cancer, high risk prostate cancer, high-risk prostate cancer, node positive prostate cancer, nod-positive prostate cancer, hypofractionation

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)MaleDoes not accept healthy volunteers

Inclusion Criteria:

  • Age > 18 years.
  • Able to provide informed consent.
  • Histologic diagnosis of prostate adenocarcinoma.
  • ECOG performance status 0-1.
  • High-risk localized disease by NCCN criteria (>cT3, Grade group >4, or PSA >20 ng/mL) or clinical N1 disease.
  • Clinical M0 by conventional imaging (computed tomography (CT) and bone scan (BS)) and/or molecular imaging (prostate specific membrane antigen (PSMA)- positron emission tomography (PET))

Exclusion Criteria:

  • Prior pelvic radiotherapy.
  • Contraindications to radiotherapy

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Moderate Hypofracitonated Boost to the Prostate with Pelvic Radiation Therapy

Arm Description

External beam radiotherapy- 60 Gy in 20 fractions to the prostate, 48 Gy in 20 fractions to the pelvis, 68 Gy in 20 fraction optional boost to prostatic dominant intraprostatic lesion, 55 Gy in 20 fraction optional boost to involved pelvic lymph nodes

Outcomes

Primary Outcome Measures

Acute Grade >2 Gastrointestinal Toxicity
Acute (less than or equal to 90 days) toxicity will be evaluated by using prospective follow-up and grading according to the latest version of the Common Terminology Criteria for Adverse Events (CTCAE) v5.0.

Secondary Outcome Measures

Patient-reported quality-of-life assessed by EPIC-26
Patient-Reported Quality of Life will be assessed at baseline and at each follow-up visit (3-weeks post intervention then every 6 months until 5 years, or more frequently if clinically necessary) using the following assessment questionnaires: 26-Item Expanded Prostate Cancer Index Composite (EPIC-26)
Measure the severity of lower urinary tract symptoms during the study
Patient-Reported symptoms will be assessed at baseline and at each follow-up visit (3-weeks post intervention then every 6 months until 5 years, or more frequently if clinically necessary) using the following assessment questionnaires: International Prostate Symptom Score (IPSS)
Graded criteria based on CTCAE version 5.0 for acute genitourinary toxicity and late genitourinary and gastrointestinal toxicity
Acute (less than or equal to 90 days) and long-term (greater than 90 days) toxicity will be evaluated by using prospective follow-up and grading according to the latest version of the Common Terminology Criteria for Adverse Events (CTCAE) v5.0.
Measure of oncologic outcomes
Time to development of castrate-resistant prostate cancer (biochemmical or ardiographic progression while having castrate levels of testosterone)
Measure of oncologic outcomes
Biochemical control rate will be assessed at baseline and at each follow-up visit (3 weeks after treatment then every 6 months until 5 years or more frequently if clinically necessary) by the blood level of prostate-specific antigen (PSA) levels
Measure of onocologic outcomes
Radiographic control rate will be assess at baseline and weekly during the radiotherapy intervention using cone beam CT or bone scan.
Prostate cancer specific survival based on death from prostate cancer
Safety will be evaluated by recording prostate cancer mortality at follow-up visits (3-weeks post intervention then every 6 months until 5 years, or more frequently if clinically necessary)
Overall survival
Safety will be evaluated by recording overall mortality at follow-up visits (3-weeks post intervention then every 6 months until 5 years, or more frequently if clinically necessary).

5. Study Description

Brief Summary
This is a single-arm phase II prospective trials that is recruiting 100 participants. The study population that is being investigated are patients with localized high-risk or node-positive prostate cancer. Participants will receive external beam radiotherapy as a moderately hypofractionated boost to the prostate with pelvic radiation therapy. Androgen deprivation therapy will be prescribed at the discretion of the treating physician as per standard of care.
