Cytoreductive radical prostatectomy versus no local treatment in patients with metastatic prostate cancer.

We identified 12 systematic reviews, including seven studies in total, none of which was a trial. Only six of those seven primary studies were used in the results summary. Despite the lack of high-quality evidence, the results summary shows the benefits of performing surgery on the primary tumor in terms of all-cause mortality, cancer-specific mortality, and disease progression. There was also a potential benefit in local complications related to the progression of the primary tumor, supporting the implementation of this intervention in patients with metastatic disease. The absence of formal recommendations highlights the need to evaluate the benefits of surgery on a case-by-case basis, presenting the available evidence to patients for a shared decision-making process and considering future local complications that could be difficult to manage.
