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.

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