Abstract
Prostate-specific membrane antigen PET is a promising diagnostic tool in prostate cancer. The gold standard for the detection of prostate tumor and lymph node metastases is histopathology. The aim of the present review was to investigate accuracy measures of 68Ga/18F-labeled prostate-specific membrane antigen PET tracers in primary and recurrent prostate cancer with systematic sector-based histopathology as the reference standard. A systematic literature search was performed and 34 studies were included. Overall, prostate-specific membrane antigen PET showed high specificity, but variable sensitivity to localize known prostate cancer and detect pelvic lymph node metastases.

Abstract
Lymph node recurrent prostate cancer is a common clinical scenario that is likely to increase significantly with the widespread adoption of novel positron emission tomography (PET) agents. Despite increasing evidence that localized therapy is disease modifying, most men with lymph node recurrent prostate cancer receive only systemic therapy with androgen deprivation therapy (ADT). For men who receive localized therapy the intent is often to delay receipt of systemic therapy. Little evidence exists on the optimal combination of local and systemic therapy in this patient population. In this hypothesis generating review, we will outline the rationale and propose a framework for combining involved field SBRT with risk adapted intermittent ADT for hormone sensitive nodal recurrent prostate cancer. In patients with a limited number of nodal metastases, involved field stereotactic body radiation therapy (SBRT) may have a role in eliminating castrate-resistant clones and possibly prolonging the response to intermittent ADT. We hypothesize that in a small percentage of patients, such a treatment approach may lead to long term remission or cure.

Abstract
Importance After radical prostatectomy, adverse pathologic features and postoperative prostate-specific antigen (PSA) levels can herald disease recurrence or progression. Postoperative radiotherapy (RT) remains beneficial in this setting. Objective To examine the evidence supporting the use of postoperative RT as well as recent advances that help determine timing, scope, and use in combination with androgen deprivation therapy (ADT) with or without lymphatic irradiation. Evidence Review A search was conducted of MEDLINE (Ovid), Embase (Elsevier), and the Cochrane Library (Wiley) databases, in addition to clinical trial registries. The reference list of included studies was reviewed for relevant articles. The search was limited to studies published between January 1, 2014, and December 31, 2019. Findings After 548 citations were screened, 27 articles were selected for inclusion. In addition to conventional imaging, positron-emission tomographic (PET)-based radiotracers can aid in disease localization. While PET imaging may influence management with RT, studies are underway examining this issue, and several limitations must be considered, such as limited detectability at lower PSA levels and regional sensitivity. Available genomic classifiers can risk stratify patients or assess potential added benefit of RT. Prospective validation is underway with cooperative group trials. Adjuvant RT, on the basis of adverse pathologic features (such as extraprostatic extension or positive margins) is beneficial in terms of disease control, but it is unclear whether this therapy translates into more meaningful clinical benefit (eg, improved overall survival and a reduction in metastasis), which has been demonstrated by only 1 older, prospective randomized study. Preliminary data suggest that for a relatively favorable-risk population (low Gleason score but with positive margins), PSA monitoring may be a reasonable alternative in some men. Use of androgen deprivation therapy and lymphatic irradiation should be considered in higher-risk cohorts (those with high PSA, high Gleason score, seminal vesicle invasion or node positivity) in conjunction with postoperative RT. Conclusions and Relevance The findings of this review suggest that postprostatectomy RT should be considered for men with prostate cancer in the setting of adverse pathologic features; in carefully selected patients with favorable characteristics, close PSA monitoring is an option. Androgen deprivation therapy and pelvic lymphatic irradiation should be considered for higher risk cohorts (eg, higher PSA values, higher Gleason score). PET imaging and molecular studies remain unproven as decision tools.

Considering the role of radical prostatectomy in 21st century prostate cancer care. Nat Rev Urol 2020; 17:177-188.

Abstract
The practice of radical prostatectomy for treating prostate cancer has evolved remarkably since its general introduction around 1900. Initially described using a perineal approach, the procedure was later popularized using a retropubic one, after it was first described as such in 1948. The open surgical method has now largely been abandoned in favour of the minimally invasive robot-assisted method, which was first described in 2000. Until 1980, the procedure was hazardous, often accompanied by massive blood loss and poor outcomes. For patients in whom surgery is indicated, prostatectomy is increasingly being used as the first step in a multitherapeutic approach in advanced local, and even early metastatic, disease. However, contemporary molecular insights have enabled many men to safely avoid surgical intervention when the disease is phenotypically indolent and use of active surveillance programmes continues to expand worldwide. In 2020, surgery is not recommended in those men with low-grade, low-volume Gleason 6 prostate cancer; previously these men - a large cohort of ~40% of men with newly diagnosed prostate cancer - were offered surgery in large numbers, with little clinical benefit and considerable adverse effects. Radical prostatectomy is appropriate for men with intermediate-risk and high-risk disease (Gleason score 7-9 or Grade Groups 2-5) in whom radical prostatectomy prevents further metastatic seeding of potentially lethal clones of prostate cancer cells. Small series have suggested that it might be appropriate to offer radical prostatectomy to men presenting with small metastatic burden (nodal and or bone) as part of a multimodal therapeutic approach. Furthermore, surgical treatment of prostate cancer has been reported in cohorts of octogenarian men in good health with minimal comorbidities, when 20 years ago such men were rarely treated surgically even when diagnosed with localized high-risk disease. As medical therapies for prostate cancer continue to increase, the use of surgery might seem to be less relevant; however, the changing demographics of prostate cancer means that radical prostatectomy remains an important and useful option in many men, with a changing indication.

Performance of [ 68Ga] Ga-PSMA 11 PET for detecting prostate cancer in the lymph nodes before salvage lymph node dissection: a systematic review and meta-analysis. Prostate Cancer Prostatic Dis 2019; 23:1-10. [PMID: 31147628 DOI: 10.1038/s41391-019-0156-z] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2019] [Revised: 03/29/2019] [Accepted: 04/03/2019] [Indexed: 02/05/2023]
Abstract
BACKGROUND Salvage lymph node dissection (sLND) for nodal recurrence in prostate cancer (PCa) patients with biochemical recurrence (BCR) is still not recommended in current guidelines, because of the diagnostic inaccuracy of current conventional imaging. To assess the performance of [68Ga] Ga-prostate-specific membrane antigen conjugate 11 positron emission tomography (PSMA-PET) in detecting PCa lymph node metastasis using pathologic confirmation through sLND. METHODS Literature search was conducted using the MEDLINE, SCOPUS, Web of Science, and Cochrane Library on November 11th, 2018 to identify the eligible studies. Studies were eligible if they investigated the diagnostic performance of PSMA-PET before sLND in PCa patients with BCR and reported the number of true positive, false positive, false negative, and true negative on a lesion-based and/or field-based analyses to compare with histopathologic findings in sLND specimens. RESULTS Fourteen studies published between 2015 and 2018 comprising 462 patients were selected in this systematic review and meta-analysis. The positive predictive value of PSMA-PET before sLND on a patient-based analysis ranged between 0.70 and 0.93. The pooled sensitivity using lesion-based and field-based analyses were 0.84 (95%CI: 0.61-0.95) and 0.82 (95%CI: 0.72-0.89), respectively. The pooled specificity using lesion-based and field-based analyses were 0.97 (95%CI: 0.95-0.99) and 0.95 (95%CI: 0.70-0.99), respectively. The diagnostic odds ratio using lesion-based and field-based analyses were 189 (95%CI: 39-920) and 82 (95%CI: 8-832), respectively. CONCLUSIONS PSMA-PET before sLND provided highly accurate performance with clinically relevant high positive and negative predictive values for detecting lymph node disease in patients with BCR after local treatment with curative intent for PCa. PSMA-PET can identify the patients who are likely to benefit from sLND and possibly direct to lesion or region-based dissection.

Abstract
BACKGROUND The Decipher genomic classifier (GC) is increasingly being used to determine metastasis risk in men with localized prostate cancer (PCa). Whether GCs predict for the presence of occult metastatic disease at presentation or subsequent metastatic progression is unknown. OBJECTIVE To determine if GC scores predict extraprostatic 68Ga prostate-specific membrane antigen (68Ga-PSMA-11) positron emission tomography (PET) positivity at presentation. DESIGN, SETTING, AND PARTICIPANTS Between December 2015 and September 2018, 91 PCa patients with both GC scores and pretreatment 68Ga-PSMA-11 PET scans were identified. Risk stratification was performed using the National Comprehensive Cancer Network (NCCN), Cancer of the Prostate Risk Assessment (CAPRA), and GC scores. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Logistic regression was used to identify factors correlated with PSMA-positive disease. RESULTS AND LIMITATIONS The NCCN criteria identified 23 (25.3%) and 68 patients (74.7%) as intermediate and high risk, while CAPRA scores revealed 28 (30.8%) and 63 (69.2%) as low/intermediate and high risk, respectively. By contrast, only 45 patients (49.4%) had high-risk GC scores. PSMA-avid pelvic nodal involvement was identified in 27 patients (29.7%). Higher GC score was significantly associated with pelvic nodal involvement (odds ratio [OR] 1.38 per 0.1 units; p=0.009) and any PSMA-avid nodal involvement (pelvic or distant; OR 1.40 per 0.1 units; p=0.007). However, higher GC score was not significantly associated with PSMA-avid osseous metastases (OR 1.11 per 0.1 units; p=0.50). Limitations include selection bias for patients able to receive both tests and the sample size. CONCLUSIONS Each 0.1-unit increase in GC score was associated with an approximate 40% increase in the odds of PSMA-avid lymph node involvement. These data suggest that patients with GC high risk might benefit from more nodal imaging and treatment intensification, potentially via pelvic nodal dissection, pelvic nodal irradiation, and/or the addition of chemohormonal agents. PATIENT SUMMARY Patients with higher genomic classifier scores were found to have more metastatic lymph node involvement on prostate-specific membrane antigen imaging.

Abstract
Recent advances in novel functional imaging techniques such as PSMA PET may now offer the ability to identify small volume metastases which may otherwise go undetected. The treatment of these lesions is controversial, particularly in the oligometastatic state. We report the case of an abdominal wall metastasis detected with PSMA imaging which we treated with surgical excision. This resulted in an undetectable PSA 6 weeks post excision.
