Targeted Biopsy, Rapid Pathology, and Immediate Surgery in USTC High-Risk Prostate Cancer: A Prospective Multicenter Study
150 participantsStarted 2026-08-01
Plain-language summary
This multicenter, prospective, single-arm study evaluates a novel streamlined pathway for men at high risk of clinically significant prostate cancer (csPCa) identified by the USTC model (probability ≥0.60). Under general anesthesia, participants undergo MRI/ultrasound fusion targeted biopsy; the cores are immediately analyzed by frozen section hematoxylin-eosin staining and rapid immunohistochemistry. If csPCa is confirmed intraoperatively, laparoscopic radical prostatectomy is performed during the same anesthesia session. The primary aims are to determine the diagnostic concordance between intraoperative rapid pathology and definitive paraffin pathology, the positive surgical margin rate at 12 months, and perioperative safety. The study enrolls 150 participants across 12 Chinese hospitals and is expected to provide evidence supporting an efficient, PET-independent, one-stage diagnostic-therapeutic strategy for clinically significant prostate cancer.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
① Patients with clinically suspected prostate cancer based on examination (e.g., DRE or PSA testing); ② Patients who have undergone serum tPSA testing and mpMRI; ③ 4 ng/mL ≤ tPSA \< 100 ng/mL; ④ Patients with a csPCa risk probability of ≥0.60 as assessed by the clinical prediction model (https://ustcprostatecancerprediction.shinyapps.io/dynnomapp/); ⑤ The patient has no significant contraindications for prostate biopsy or radical prostatectomy.
Exclusion Criteria:
① No complete serum tPSA test or mpMRI scan; ② tPSA \< 4 ng/mL or ≥ 100 ng/mL; ③ Based on assessment by a clinical prediction model, the patient's probability of csPCa is \< 0.60; ④ Patients with a history of multiple biopsies showing no evidence of clinically significant prostate cancer; ⑤ Patients in poor general health who cannot tolerate a biopsy; ⑥ Patients with severe bleeding disorders or those currently undergoing anticoagulant therapy.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Positive Predictive Value (PPV) of intraoperative frozen section combined with rapid immunohistochemistry for clinically significant prostate cancer (csPCa)
Timeframe: At the time of final paraffin pathology report (usually within 7-14 days after surgery)
