Impact of treatment on prostate cancer with limited metastasis

OLIGOS: Impact of Treatment on Primary Tumour in Patients With Newly Diagnosed Oligometastatic Neoplasia of the Prostate

Observational Istituto Oncologico Veneto IRCCS · NCT06273345

This study is testing how well local treatments like surgery or radiation, combined with hormone therapy, can help men with early-stage prostate cancer that has spread a little, and how these treatments affect their quality of life.

What this trial studies

This multicentre prospective observational study aims to create a registry of patients with newly diagnosed oligometastatic prostate carcinoma, following CHAARTED criteria. It will evaluate the oncological outcomes and quality of life impacts of local treatment (surgery or radiotherapy) combined with systemic hormonal therapy. The study focuses on patients with low-volume metastatic disease, ensuring they do not have high metastatic volume characteristics. Data will be collected from major urological centers in the Triveneto region.

Who should consider this trial

Good fit: Ideal candidates are patients with newly diagnosed oligometastatic prostate carcinoma who meet specific low-volume metastatic criteria.

Not a fit: Patients with high-volume metastatic disease or those with poor performance status may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the effectiveness of local treatments combined with systemic therapy for patients with oligometastatic prostate cancer.

How similar studies have performed: Other studies have shown promising results with similar approaches in treating oligometastatic prostate cancer, suggesting potential for success.
