New Scan-Guided radiation aims to cut side effects in recurrent prostate cancer
NCT ID NCT07234981
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether using a special PET scan (PSMA-PET) to guide radiation can reduce short-term side effects in men whose prostate cancer returns after surgery. About 54 men will receive targeted radiation to the pelvis plus a boost to spots seen on the scan, along with standard hormone therapy. The goal is to see if this approach causes fewer moderate-to-severe side effects than standard radiation while still controlling the cancer.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Prior biopsy proven prostate cancer for which they underwent a radical prostatectomy with curative intent. 2. Evidence of biochemical recurrence as defined by NCCN: Persistent positive PSA post-radical prostatectomy (RP) or an undetectable PSA after RP with a subsequent detectable PSA that increases on ≥2 determinations (PSA recurrence) or increases to PSA \>0.1 ng/mL. 3. Targetable PSMA-avid lesion within the prostate bed, pelvic lymph nodes, or both and/or targetable lesion in prostate bed defined on MRI suspicious for local recurrence. 4. If lesions are amenable for biopsy this may be attempted, but biopsy proven recurrence/persistence is not required for trial enrollment. 5. Life expectancy greater than 5 years. 6. Karnofsky performance status ≥ 80 or Eastern Cooperative Oncology Group performance status ≤ 2 within 14 days prior to registration. 7. Age ≥ 30 years. 8. Patient must be able to provide study-specific informed consent prior to study entry. Exclusion Criteria: 1. Evidence of distant metastatic disease outside the pelvic lymph nodes (including osseous pelvic disease). 2. Presence of any psychological, familial, sociological, or geographical condition potentially hampering compliance with the study protocol and follow-up schedule, including alcohol dependence or drug abuse. 3. Relative or absolute contraindications to radiation therapy as determined by the treating physician. These include but are not limited to inflammatory bowel disease, connective tissue disorders (systemic lupus erythematosus, scleroderma, etc.), and genetic disorders that risk increased sensitivity to radiation therapy.
