Abstract
PURPOSE OF REVIEW Metastatic prostate cancer (PCa) continues to be an invariably fatal condition. While historically, de-novo metastatic PCa was primarily treated with androgen deprivation therapy (ADT) and systemic therapy, there is a growing trend toward incorporating local treatments in the early management of the disease. This is particularly applicable to men with oligometastatic PCa (OMPC), which represents an 'intermediate phase' between localized and disseminated metastatic disease. Local treatment offers an opportunity for disease control before it progresses to a more advanced stage. This review discussed the current evidence for local treatment options for OMPC. RECENT FINDINGS Currently, it has been suggested that men with OMPC may have a more indolent course and, therefore, favorable outcomes may be observed with metastasis-directed therapy (MDT). This review will not address the role of MDT to patients with OMPC but will focus on local treatments of the primary disease. The three main forms of local therapy employed for OMPC are cryotherapy, radiation therapy, and cytoreductive prostatectomy (CRP). Whole gland cryotherapy, either with ADT or with ADT and systemic chemotherapy, has shown some limited promising results. Radiation therapy combined with ADT has also demonstrated improvements in progression-free survival in clinical trials (primarily STAMPEDE Arm G and HORRAD). CRP often combined with ADT has emerged as a potential strategy for managing OMPC, with promising findings primarily from retrospective studies. Currently, several randomized controlled trials are underway to further investigate the role of CRP in the oligometastatic setting. SUMMARY OMPC has become a unique category of disease with specific therapeutic implications. Lack of robust clinical data renders treatment selection controversial. Further studies with long follow up are necessary to identify men with oligometastatic disease who will benefit from local treatment.

A Novel Nomogram to Identify Candidates for Focal Therapy Among Patients with Localized Prostate Cancer Diagnosed via Magnetic Resonance Imaging-Targeted and Systematic Biopsies: A European Multicenter Study. Eur Urol Focus 2023; 9:992-999. [PMID: 37147167 DOI: 10.1016/j.euf.2023.04.008] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2023] [Revised: 03/12/2023] [Accepted: 04/21/2023] [Indexed: 05/07/2023]
Abstract
BACKGROUND Suitable selection criteria for focal therapy (FT) are crucial to achieve success in localized prostate cancer (PCa). OBJECTIVE To develop a multivariable model that better delineates eligibility for FT and reduces undertreatment by predicting unfavorable disease at radical prostatectomy (RP). DESIGN, SETTING, AND PARTICIPANTS Data were retrospectively collected from a prospective European multicenter cohort of 767 patients who underwent magnetic resonance imaging (MRI)-targeted and systematic biopsies followed by RP in eight referral centers between 2016 and 2021. The Imperial College of London eligibility criteria for FT were applied: (1) unifocal MRI lesion with Prostate Imaging-Reporting and Data System score of 3-5; (2) prostate-specific antigen (PSA) ≤20 ng/ml; (3) cT2-3a stage on MRI; and (4) International Society of Urological Pathology grade group (GG) 1 and ≥6 mm or GG 2-3. A total of 334 patients were included in the final analysis. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The primary outcome was unfavorable disease at RP, defined as GG ≥4, and/or lymph node invasion, and/or seminal vesicle invasion, and/or contralateral clinically significant PCa. Logistic regression was used to assess predictors of unfavorable disease. The performance of the models including clinical, MRI, and biopsy information was evaluated using the area under the receiver operating characteristic curve (AUC), calibration plots, and decision curve analysis. A coefficient-based nomogram was developed and internally validated. RESULTS AND LIMITATIONS Overall, 43 patients (13%) had unfavorable disease on RP pathology. The model including PSA, clinical stage on digital rectal examination, and maximum lesion diameter on MRI had an AUC of 73% on internal validation and formed the basis of the nomogram. Addition of other MRI or biopsy information did not significantly improve the model performance. Using a cutoff of 25%, the proportion of patients eligible for FT was 89% at the cost of missing 30 patients (10%) with unfavorable disease. External validation is required before the nomogram can be used in clinical practice. CONCLUSIONS We report the first nomogram that improves selection criteria for FT and limits the risk of undertreatment. PATIENT SUMMARY We conducted a study to develop a better way of selecting patients for focal therapy for localized prostate cancer. A novel predictive tool was developed using the prostate-specific antigen (PSA) level measured before biopsy, tumor stage assessed via digital rectal examination, and lesion size on magnetic resonance imaging (MRI) scans. This tool improves the prediction of unfavorable disease and may reduce the risk of undertreatment of localized prostate cancer when using focal therapy.
