Using radioligand therapy before surgery for prostate cancer with limited metastases

Neoadjuvant [177Lu]Lu-PSMAI&T Radioligand Therapy (PSMA-RLT) for Patients With Oligometastatic Prostate Cancer Diagnosed Using [68Ga]Ga-PSMA-11 PET Imaging Followed by Radical Prostatectomy: A Prospective Phase II Pilot Study

Phase 2 Interventional Medical University of Vienna · NCT06259123

This study is testing if a special type of radiation treatment before surgery can help men with prostate cancer that has spread a little, to see if it improves their health outcomes.

What this trial studies

This phase II clinical trial evaluates the effectiveness of systemic radioligand therapy using [177Lu]Lu-PSMAI&T in patients with oligometastatic prostate cancer who are scheduled for radical prostatectomy. The study aims to assess the response in terms of prostate-specific antigen (PSA) levels, imaging results, and pathological outcomes. A total of ten patients diagnosed with oligometastatic prostate cancer via [68Ga]Ga-PSMA-11 PET imaging will be included to determine the therapy's impact on oncological outcomes.

Who should consider this trial

Good fit: Ideal candidates are patients with oligometastatic prostate cancer diagnosed with limited metastases and who are eligible for radical prostatectomy.

Not a fit: Patients with nonmetastatic prostate cancer or those with extensive metastases beyond the study's criteria may not benefit from this treatment.

Why it matters

Potential benefit: If successful, this approach could improve treatment outcomes for patients with oligometastatic prostate cancer by enhancing the effectiveness of surgery.

How similar studies have performed: While this approach is innovative, similar studies using radioligand therapy in prostate cancer have shown promising results, indicating potential for success.
