ASO Author Reflections: It Does Not Matter Whether Radical Prostatectomy is Performed in High-Risk Localized Disease or at the Oligometastatic Stage.

Radical prostatectomy (RP) alone has traditionally been considered insufficient for patients with high-risk localized prostate cancer (HRPC) owing to the frequent need for adjuvant salvage radiotherapy or androgen deprivation therapy (ADT) following surgery. Previously, systemic therapy, such as ADT, was the standard treatment for metastatic prostate cancer (PC) patients; RP was not considered viable for these patients. However, since 2015, there has been a recognition that metastatic PC patients can be categorized based on the extent of their metastases, leading to the consideration of RP for some metastatic cases. In recent years, the concept of cytoreductive RP has gained traction; studies suggest that it may improve survival rates in metastatic PC patients through mechanisms, such as tumor debulking and enhancement of the immune response. A meta-analysis of retrospective studies has shown that cytoreductive RP is associated with higher cancer-specific survival rates at 1-year, 3-year, and 5-year intervals compared with systemic therapy alone. In our study, which followed HRPC and oligometastatic PC patients for an average of 46 months, we observed biochemical recurrence in 17.8% of HRPC and 13% of oligometastatic patients, with overall survival rates of 96.4% and 87%, respectively. Although prospective or randomized studies are still lacking, current retrospective studies, including our own, suggest promising outcomes for RP in HRPC and oligometastatic patients. With the increasing prevalence of robotic surgery, improved pelvic anatomy observation, and growing surgical confidence, the realization of prospective randomized study results may not be far off.
