Abstract
Metastatic hormone-naïve prostate cancer (mHNPC) is often the initial form of presentation for metastatic prostate cancer and encompasses a heterogeneous patient population with high inter-patient heterogeneity in prognosis and response to therapy. A more precise treatment of mHNPC, guided by evidence-based biomarkers, remains an unmet medical need. In addition, the limited number of representative laboratory models of mHNPC hampers the translation of basic research into clinical applications. We provide a comprehensive overview of the clinical and biological features that characterize mHNPC, highlight molecular data that could explain the unique prognostic characteristics of mHNPC, and identify key open questions.

Abstract
PURPOSE OF REVIEW The implementation of PET with prostate-specific membrane antigen (PSMA) tracer as primary staging tool occurred recently. Since its introduction, a novel category of patients emerged, with negative staging at conventional imaging, and positive molecular imaging. Local treatment in these patients might be associated with improved oncological outcomes when combined with systemic therapy. However, its impact on oligometastatic prostate cancer (omPCa) remains unknown. In this review, we aimed at investigating the role of cytoreductive radical prostatectomy (cRP) in oligometastatic disease at molecular imaging. RECENT FINDINGS After comprehensive review of literature, two retrospective studies highlighted the feasibility, safety, and potential benefits of surgery in omPCA patients at molecular imaging. They showed that 72% of patients achieved PSA less than 0.01 ng/ml following cRP as part of a multimodal approach, 17% experienced radiographic progression, and 7% died at 27-month median follow-up. Moreover, complications postcRP after PSMA PET were modest, with a 40% rate of any adverse event, and 5% of grade more than 3. The 1-year urinary continence after cRP rate was 82%. The oncological, functional outcomes and the complication rate aligned with those observed in series of cRP after conventional imaging. SUMMARY cRP is feasible, well tolerated, and effective in selected patients with omPCa at PSMA PET.

Men with metastatic prostate cancer carrying a pathogenic germline variant in breast cancer genes: disclosure of genetic test results to relatives. Fam Cancer 2024; 23:165-175.

Abstract
Some patients with metastatic prostate cancer carry a pathogenic germline variant (PV) in a gene, that is mainly associated with an increased risk of breast cancer in women. If they test positive for such a PV, prostate cancer patients are encouraged to disclose the genetic test result to relatives who are at risk in case the carrier status changes the relatives' medical care. Our study aimed to investigate how men who learned they carry a PV in BRCA1, BRCA2, PALB2, CHEK2 or ATM disclosed their carrier status to at-risk relatives and to assess the possible psychological burden for the carrier and their perception of the burden for relatives. In total, 23 men with metastatic prostate cancer carrying a PV completed the IRI questionnaire about family communication; 14 also participated in a semi-structured interview. Patients felt highly confident in discussing the genetic test result with relatives. The diagnosis of prostate cancer was experienced as a burden, whereas being informed about genetic testing results did in most cases not add to this burden. Two patients encountered negative experiences with family communication, as they considered the genetic test result to be more urgent than their relatives. This mixed-methods study shows that metastatic prostate cancer patients with a PV in genes mainly associated with increased risk of breast cancer feel well-equipped to communicate about this predisposition in their families. Carriers felt motivated to disclose their genetic test result to relatives. Most of them indicated that the disclosure was not experienced as a psychological burden.

Screening history and risk of death from prostate cancer: a nested case-control study within the screening arm of the Finnish Randomized Study of Screening for Prostate Cancer (FinRSPC).

Abstract
PURPOSE We assessed the risk of death from prostate cancer (PCa) in relation to men's screening histories, i.e., screening attendance among men who were offered screening. METHODS Men in the Finnish Randomized Study of Screening for Prostate Cancer (FinRSPC) screening arm were invited to up to three screening rounds with the serum prostate-specific antigen (PSA) test at 4-year intervals during 1996-2007. Case subjects (n = 330) were men who died from PCa. Each case was matched to five controls (n = 1544) among the men who were free of PCa. Screening history was defined as (1) never/ever attended screening prior to the case diagnosis; (2) attended at the first screening round; and (3) recency of screening, calculated as the time from last screening attendance to the date of case diagnosis. The association between screening history and the risk of death from PCa was estimated by odds ratios (OR) with 95% confidence intervals (CI) using conditional logistic regression. RESULTS Having ever attended screening versus never attended was associated with a reduced risk of PCa death (OR 0.60, 95% CI 0.45-0.81) and a similar association was found for those attended (versus not attended) the first screening round (OR 0.67, 95% CI 0.51-0.87). The effect by time since last screen for the risk of PCa death was significantly lower 2-7 years since last screen. CONCLUSION Among men invited to screening, subjects who attended any PSA screening during the previous 19 years had a 40% reduction in PCa mortality compared to non-screened men.

A Pilot Study on Patient-specific Computational Forecasting of Prostate Cancer Growth during Active Surveillance Using an Imaging-informed Biomechanistic Model. CANCER RESEARCH COMMUNICATIONS 2024; 4:617-633. [PMID: 38426815 PMCID: PMC10906139 DOI: 10.1158/2767-9764.crc-23-0449] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Revised: 12/15/2023] [Accepted: 02/09/2024] [Indexed: 03/02/2024]
Abstract
Active surveillance (AS) is a suitable management option for newly diagnosed prostate cancer, which usually presents low to intermediate clinical risk. Patients enrolled in AS have their tumor monitored via longitudinal multiparametric MRI (mpMRI), PSA tests, and biopsies. Hence, treatment is prescribed when these tests identify progression to higher-risk prostate cancer. However, current AS protocols rely on detecting tumor progression through direct observation according to population-based monitoring strategies. This approach limits the design of patient-specific AS plans and may delay the detection of tumor progression. Here, we present a pilot study to address these issues by leveraging personalized computational predictions of prostate cancer growth. Our forecasts are obtained with a spatiotemporal biomechanistic model informed by patient-specific longitudinal mpMRI data (T2-weighted MRI and apparent diffusion coefficient maps from diffusion-weighted MRI). Our results show that our technology can represent and forecast the global tumor burden for individual patients, achieving concordance correlation coefficients from 0.93 to 0.99 across our cohort (n = 7). In addition, we identify a model-based biomarker of higher-risk prostate cancer: the mean proliferation activity of the tumor (P = 0.041). Using logistic regression, we construct a prostate cancer risk classifier based on this biomarker that achieves an area under the ROC curve of 0.83. We further show that coupling our tumor forecasts with this prostate cancer risk classifier enables the early identification of prostate cancer progression to higher-risk disease by more than 1 year. Thus, we posit that our predictive technology constitutes a promising clinical decision-making tool to design personalized AS plans for patients with prostate cancer. SIGNIFICANCE Personalization of a biomechanistic model of prostate cancer with mpMRI data enables the prediction of tumor progression, thereby showing promise to guide clinical decision-making during AS for each individual patient.

Abstract
In recent years, several systemic therapies have been introduced for metastatic hormone-sensitive prostate cancer, including androgen deprivation therapy (ADT) combined with docetaxel (Doc) and/or new-generation androgen receptor signaling inhibitors (ARSI). Trials evaluating ADT + ARSI have consistently demonstrated an overall survival (OS) benefit for doublet therapy over ADT alone. Similarly, the STOPCaP meta-analysis showed an OS benefit in favor of ADT + Doc versus ADT alone. ARSI, Doc, and ADT have different antitumor mechanisms, thus potentiating the effect of combination therapy. Two randomized trials showed that the addition of ARSI to ADT + Doc improves OS, especially for synchronous high-volume disease. However, the real question about triplet therapy remains unanswered: whether combining Doc with ARSI improves outcomes compared to ADT + ARSI. As there are no head-to-head comparisons, this narrative review aims to summarize the current evidence regarding triplet therapy versus doublet therapy including ADT+ ARSI.

Abstract
Currently, prostate cancer (PCa) poses a global risk to the well-being of males. Over the past few years, the utilization of prostate-specific antigen (PSA) screening has become prevalent in the identification and management of PCa, which has promoted a large number of patients with advanced PCa to receive timely treatment and reduce the mortality. Nevertheless, the utilization of PSA in PCa screening has sparked debate, and certain research has validated the potential for overdiagnosis and overtreatment associated with PSA screening. Hence, in order to decrease the mortality rate of PCa patients and prevent unnecessary diagnosis and treatment, it is crucial to carefully choose the suitable population and strategy for PSA screening in PCa. In this systematic review, the clinical studies on PSA screening for the diagnosis and treatment of PCa were thoroughly examined. The review also delved into the effects and mechanisms of PSA screening on the prognosis of PCa patients, examined the factors contributing to overdiagnosis and overtreatment, and put forth strategies for optimization. The objective of this research is to offer valuable recommendations regarding the utilization of PSA screening for the detection and management of PCa.

Abstract
De novo metastatic hormone-sensitive PC (mHSPC) accounts for 5-10% of all prostate cancer (PC) diagnoses but it is responsible for nearly 50% of PC-related deaths. Since 2015, the prognosis of mHSPC has slightly improved thanks to the introduction of new hormonal agents and chemotherapy combined with androgen deprivation therapy from the first-line setting. This review describes the current therapeutic opportunities for de novo mHSPC, focusing on potential molecular biomarkers identified in the main clinical trials that have modified the standard of care, the genomic features of de novo mHSPC, and the principal ongoing trials that are investigating new therapeutic approaches and the efficacy of a biomarker-guided treatment in this setting. The road toward personalized treatment for de novo mHSPC is still long, considering that the randomized clinical trials, which have furnished the basis of the current therapeutic options, stratified patients according to clinical criteria that did not necessarily reflect the biological rationale of the chosen therapy. The role of transcriptomic profiling of mHSPC as a predictive biomarker requires further validation, and it remains to be ascertained how the genomic variants detected in mHSPC, which are regarded as predictive in the castration-resistant disease, can be exploited in the mHSPC setting.

Abstract
BACKGROUND Considering the long natural history of prostate cancer (PCa), long-term results of the European Randomised Study of Screening for PCa (ERSPC) are crucial. OBJECTIVE To provide an update on the effect of prostate-specific antigen (PSA)-based screening on PCa-specific mortality (PCSM), metastatic disease, and overdiagnosis in the Dutch arm of the ERSPC. DESIGN, SETTING, AND PARTICIPANTS Between 1993 and 2000, a total of 42376 men, aged 55-74 yr, were randomised to a screening or a control arm. The main analysis was performed with men aged 55-69 yr (n = 34831). Men in the screening arm were offered PSA-based screening with an interval of 4 yr. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Intention-to-screen analyses with Poisson regression were used to calculate rate ratios (RRs) of PCSM and metastatic PCa. RESULTS AND LIMITATIONS After a median follow-up of 21 yr, the RR of PCSM was 0.73 (95% confidence interval [CI]: 0.61-0.88) favouring screening. The numbers of men needed to invite (NNI) and needed to diagnose (NND) to prevent one PCa death were 246 and 14, respectively. For metastatic PCa, the RR was 0.67 (95% CI: 0.58-0.78) favouring screening. The NNI and NND to prevent one metastasis were 121 and 7, respectively. No statistical difference in PCSM (RR of 1.18 [95% CI: 0.87-1.62]) was observed in men aged ≥70 yr at the time of randomisation. In the screening arm, higher rates of PCSM and metastatic disease were observed in men who were screened only once and in a selected group of men above the screening age cut-off of 74 yr. CONCLUSIONS The current analysis illustrates that with a follow-up of 21 yr, both absolute metastasis and mortality reduction continue to increase, resulting in a more favourable harm-benefit ratio than demonstrated previously. These data do not support starting screening at the age of 70-74 yr and show that repeated screening is essential. PATIENT SUMMARY Prostate-specific antigen-based prostate cancer screening reduces metastasis and mortality. Longer follow-up shows fewer invitations and diagnoses needed to prevent one death, a positive note towards the issue of overdiagnosis.

Abstract
INTRODUCTION The healthcare level has been greatly affected by the COVID-19 pandemic compared with before the outbreak. This study aimed to review the impact of COVID-19 on the screening and diagnosis of prostate cancer (PCa). METHOD The current study was designed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020. The keywords used to perform the search strategy were COVID-19 and prostate neoplasms. The four primary electronic databases comprising PubMed/MEDLINE, Web of Science, Scopus and Embase were searched until 1 September 2022. After screening and selecting studies through the EndNote software, data were extracted from each included study by two independent authors. All studies were evaluated according to Newcastle-Ottawa Scale quality assessment tool. RESULTS As a result, 40 studies were included, categorised into two subjects. The majority of studies indicated a significant decrease in screening prostate-specific antibody tests during the COVID-19 pandemic compared with the pre-pandemic period, leading to delays in cancer diagnosis. The decrease in the number of diagnosed cases with low/intermediate stages to some extent was more than those with advanced stages. The PCa screening and diagnosis reduction ranged from nearly 0% to 78% and from 4.1% to 71.7%, respectively. CONCLUSION Our findings showed that during the COVID-19 lockdown, delays in PCa screening tests and diagnoses led to the negative health effects on patients with PCa. Thus, it is highly recommended performing regular cancer screening to reduce the impact of the COVID-19 lockdown. PROSPERO REGISTRATION NUMBER CRD42021291656.

Abstract
Background The ERSPC study has demonstrated that prostate-specific antigen (PSA)-based screening results in a relative increase in diagnosis of (low-risk) prostate cancer (PCa) and a reduction in metastatic disease and PCa mortality. Objective To evaluate the burden of PCa among men randomized to active screening compared to those in the control arm in ERSPC Rotterdam. Design setting and participants We analyzed data for participants in the Dutch section of the ERSPC, including 21 169 men randomized to the screening arm and 21 136 randomized to the control arm. Men in the screening arm were invited for PSA-based screening every 4 yr, and transrectal ultrasound-guided prostate biopsy was recommended for those with PSA ≥3.0 ng/ml. Outcome measurements and statistical analysis We analyzed detailed follow-up and mortality data up to January 1, 2019, to a maximum of 21 yr, using multistate models. Results and limitations At 21 yr, 3046 men (14%) had been diagnosed with nonmetastatic PCa and 161 (0.76%) with metastatic PCa in the screening arm. In the control arm, 1698 men (8.0%) had been diagnosed with nonmetastatic PCa and 346 (1.6%) with metastatic PCa. In comparison to the control arm, men in the screening arm were diagnosed with PCa almost 1 yr earlier and if diagnosed with nonmetastatic PCa lived on average for almost 1 yr longer without disease progression. Among those who experienced biochemical recurrence (18-19% after nonmetastatic PCa), progression to metastatic disease or death was quicker in the control arm: men in the screening arm lived for 7.17 yr without progression, while the progression-free interval was only 1.59 yr for men in the control arm over a 10-yr time period. Among those who experienced metastatic disease, men in both study arms lived for 5 yr over a 10-yr time period. Conclusions PCa diagnosis was earlier after study entry for men in the PSA-based screening arm. However, disease progression was not as fast in the screening arm as in the control arm: once men in the control arm experienced biochemical recurrence, progression to metastatic disease or death was 5.6 yr faster than in the screening arm. Our results confirm the ability of early disease detection to reduce suffering and death from PCa at the cost of earlier (and more frequent) treatment-induced reductions in quality of life. Patient summary Our study shows that early detection of prostate cancer can reduce suffering and death from this disease. However, screening based on measurement of prostate-specific antigen (PSA) can also result in an earlier treatment-induced reduction in quality of life.

Abstract
Visceral metastasis (VM) and a higher number of bone metastasis generally define high volume/risk in patients with metastatic castration-sensitive prostate cancer (mCSPC). Subgroup analysis of pivotal trials did not show a clear benefit of second-generation non-steroidal anti-androgens (NSAAs) in patients with VM. However, subgroup analysis of the trial assessing abiraterone acetate, a CYP 17 inhibitor, plus prednisone (AAP) showed an improved overall survival (OS) in patients with mCSPC with VM. We searched MEDLINE, Web of Science, and congress abstracts for the phase III randomized controlled trials of second-generation NSAAs and AAP in patients with mCSPC. In this pooled analysis, we included 6485 patients from the 6 phase III trials. The rate of patients with VM was 15.2%. Interestingly, in contrast to NSAAs, AAP seems to be effective in improving OS among patients with VM (hazard ratio, HR: 0.89, 95% CI, 0.72-1.11, P = .30 for second-generation NSAAs; HR: 0.58, 95% CI, 0.40-0.84, P = .004 for AAP). In contrast, both second-generation NSAAs (HR: 0.63, 95% CI, 0.57-0.70, P < .001) and AAP (HR: 0.68, 95% CI, 0.57-0.81, P < .001) improved OS in patients without VM. In this pooled analysis, we demonstrate that while AAP provided an OS improvement in patients with VM, second-generation NSAAs did not demonstrate a similar OS benefit in this population.

Abstract
BACKGROUND In international guidelines, germline genetic testing is recommended for patients with metastatic prostate cancer. Before undergoing germline genetic testing, these patients should receive pre-test counseling. In the standard genetic care pathway, pre-test counseling is provided by a healthcare professional of a genetics department. Because the number of patients with metastatic prostate cancer is large, the capacity in the genetics departments might be insufficient. Therefore, we aim to implement so-called mainstream genetic testing in the Netherlands for patients with metastatic prostate cancer. In a mainstream genetic testing pathway, non-genetic healthcare professionals discuss and order germline genetic testing. In our DISCOVER study, we will assess the experiences among patients and non-genetic healthcare professionals with this new pathway. METHODS A multicenter prospective observational cohort study will be conducted in 15 hospitals, in different regions of the Netherlands. We developed an online training module on genetics in prostate cancer and the counseling of patients. After completion of this module, non-genetic healthcare professionals will provide pre-test counseling and order germline genetic testing in metastatic prostate cancer patients. Both non-genetic healthcare professionals and patients receive three questionnaires. We will determine the experience with mainstream genetic testing, based on satisfaction and acceptability. Patients with a pathogenic germline variant will also be interviewed. We will determine the efficacy of the mainstreaming pathway, based on time investment for non-genetic healthcare professionals and the prevalence of pathogenic germline variants. DISCUSSION This study is intended to be one of the largest studies on mainstream genetic testing in prostate cancer. The results of this study can improve the mainstream genetic testing pathway in patients with prostate cancer. TRIAL REGISTRATION The study is registered in the WHO's International Clinical Trials Registry Platform (ICTRP) under number NL9617.

Abstract
Background Attempts to reduce prostate cancer (PC) mortality require an understanding of temporal changes in the characteristics of men with lethal PC. Objective To describe the diagnostic characteristics of and time trends for a nationwide population-based cohort of Swedish men who died from PC between 1992 and 2016. Design, setting, and participants Men with PC as the underlying cause of death from 1992 to 2016 according to the Swedish Cause of Death Register were included in the study. Characteristics at diagnosis were collected via links to other nationwide registries using personal identity numbers. Outcome measurements and statistical analysis Data on disease duration, age at death, and risk category were analyzed. Missing data for risk categories for men with an early date of PC diagnosis were imputed according to the method of chained equations. Results and limitations Between 1992 and 2016, age-standardized PC mortality decreased by 25%. Median PC disease duration increased from 3.3 yr (interquartile range [IQR] 1.6–6.3) to 5.9 yr (IQR 2.5–10.3) and the median age at death from PC increased from 78.9 yr (IQR 73.3–84.2) to 82.2 yr (IQR 75.2–87.5). The proportion of men with localized disease at diagnosis who died from PC increased from 34% to 48%, while the rate of distant metastases at diagnosis decreased from 56% to 42%. The rate of distant metastases at diagnosis was highest among the youngest men. Treatment trajectories could not be described owing to the large proportion of missing data before the start of registration in the National Prostate Cancer Registry. Conclusion Age-standardized PC mortality has decreased substantially since 1992. However, there is still a high proportion of men who die from PC who had localized disease at diagnosis, which indicates that more attention is needed to identify the underlying causes to prevent disease progression. Since the proportion of men with distant metastases at diagnosis remains high, early detection of lethal tumors is essential to further reduce PC mortality. Patient summary We investigated the characteristics of men who died from prostate cancer in Sweden between 1992 and 2016. We found that men with lethal prostate cancer live longer and are older when they die today in comparison to men who died at the beginning of the study period. However, the proportion of men with distant metastases at diagnosis remains high, which is why early detection of lethal tumors is essential to reduce mortality.

Abstract
BACKGROUND AND AIMS PSA testing practice results in a large number of unnecessary prostate biopsies and the overdiagnosis of clinically insignificant prostate cancer (PCa). The aim of our study was to evaluate the value of PHI and PHID for the detection of PCa. MATERIALS AND METHODS We measured tPSA, fPSA and p2PSA in 455 patients scheduled for biopsy, including 243 patients with PCa. D'Amico criteria were used to classify these patients in three groups related to risk of progression. Intermediate- and high-risk PCa were considered as aggressive PCa. RESULTS The best area under the curve (AUC) value obtained in the detection of aggressive PCa was achieved for PHI and PHID (0.766 and 0.760, respectively). We found a relationship of the performance of by these tests with the calculated prostate volume or the estimated prostate size by digital rectal exam, obtaining the higher AUC in patients with a small prostate. Thus, the AUC for PHI was 0,843 for patients with small calculated prostate volume and 0,817 for patients with small estimated prostate size. CONCLUSIONS Our results underline that PHI and PHID outperforms the efficacy obtained with tPSA and %fPSA. Substantial differences in their value in relation to prostate volume were found.

Abstract
IMPORTANCE The US Preventive Services Task Force (USPSTF) has recommended against routine prostate-specific antigen (PSA)-based prostate cancer (PCa) screening, initially for men older than 75 years in 2008, and then for all men in 2012. Concern has been raised that, by recommending against screening, and thus early detection, the USPSTF recommendations may be associated with an increase in the incidence of metastatic PCa (mPCa). OBJECTIVE To explore the incidence of mPCa before and after the USPSTF recommendations against routine PCa screening. DESIGN, SETTING, AND PARTICIPANTS This population-based cohort study used the recently released Surveillance, Epidemiology, and End Results (SEER) 18 registry incidence data to identify men aged 45 years and older with a diagnosis of invasive PCa from 2004 through 2018. Data were analyzed from January 1, 2004 to December 31, 2018. EXPOSURE Outcomes were assessed before vs after the USPSTF recommendations against routine screening. MAIN OUTCOMES AND MEASURES Annual age-adjusted incidence rates per 100 000 population of mPCa (defined using SEER Summary Stage and American Joint Committee on Cancer [AJCC] staging systems), with adjustments for age structure and reporting delay from 2004 to 2011, according to race and age were examined. Annual percentage changes (APCs) were calculated to quantify changes in the annual incidence rates. RESULTS From 2004 to 2018, a total of 836 282 patients with PCa were recorded in the SEER database; 26 642 (56.5%) distant mPCa cases were reported in men aged 45 to 74 years, and 20 507 (43.5%) cases were reported in men aged 75 years or older. Among men aged 45 to 74 years, the incidence rate of distant mPCa (SEER Summary staging) remained stable during 2004 to 2010 (APC, -0.4%; 95% CI, -1.7% to 1.1%; P = .60), then increased significantly during 2010 to 2018 (APC, 5.3%; 95% CI, 4.5% to 6.0%; P < .001). In men aged 75 years or older, the incidence rate of distant mPCa decreased from 2004 to 2011 (APC, -1.5%; 95% CI, -3.0% to 0%; P = .046), and then increased from 2011 to 2018 (APC, 6.5%; 95% CI, 5.1% to 7.8%; P < .001). Similar trends were also seen for M1 mPCa defined per the AJCC staging system. These increased trends in mPCa incidence were particularly significant in non-Hispanic White men (2010-2018 APC, 6.9%; 95% CI, 5.4% to 8.4%; P < .001). CONCLUSIONS AND RELEVANCE Analysis of the emerging trends from the most recently released SEER data set (2004-2018) suggests that the incidence rates of mPCa have increased significantly and coincide temporally with the USPSTF recommendations against PCa screening across races and age groups. These mPCa trends are associated with reported changes in screening practices following the USPSTF recommendations.

Abstract
BACKGROUND The 2008 and 2012 United States Preventive Services Task Force (USPSTF) recommendations against prostate-specific antigen (PSA) screening have led to changes in the incidence pattern of prostate cancer. We sought to examine rates and trends in stage-specific prostate cancer incidence by age and race/ethnicity using the most recent data obtained from Surveillance, Epidemiology, and End Results (SEER) program. METHODS SEER*Stat version 8.3.6 was used to analyze annual prostate cancer incidence rates between 2000 and 2017 according to the SEER summary stage, age group, and race/ethnicity group. Incidence rates per 100,000 men were calculated and age-adjusted to 2000 US standard population. Annual percentage change (APC) was performed to identify the trend in prostate cancer incidence. RESULTS Between 2008 and 2012, trends in incidence of overall and localized prostate cancer significantly declined in comparison with between 2000 and 2007 (APC, -5.4 and -6.0, respectively). However, there was an increase in the incidence rate of both overall and localized prostate cancer from 2014 to 2017 (43.3-46 and 34-34.9 per 100,000 men, respectively). The incidence of regional prostate cancer significantly increased between 2013 and 2017 (5.9-6.8 per 100,000 men; APC, 4.3). Distant disease incidence increased continually between 2008 and 2012 (2.9-3.3 per 100,000 men; APC, 2.3) and between 2013 and 2017 (3.4-4.3 per 100,000 men; APC, 6.0). In addition, these increases in incidence occurred in men of all stratified age and race/ethnicity groups, except for men aged <50 years and American Indian/Alaska Native men. CONCLUSION This study demonstrates that the longer-term effects of USPSTF recommendations against PSA screening may have resulted in a reversal of downtrend in prostate cancer incidence, as incidence rates of overall and localized prostate cancer gradually increased from 2014 to 2017. Meanwhile, the trend in stage migration toward advanced disease increased incrementally.

Abstract
BACKGROUND About 5% of prostate cancer cases are metastatic at diagnoses. Radiotherapy of both primary tumor and secondary lesions can be, in addition to systemic treatments, a radical alternative for selected patients. MATERIALS AND METHODS Patients with de novo prostate carcinoma with bone or lymph node metastases were retrospectively reviewed. All patients received moderate hypofractionated IMRT/VMAT up to 63 Gy in 21 daily fractions of 3 Gy to prostate and metastases with neoadjuvant and concurrent androgen deprivation therapy (ADT). According to known advances some patients also received abiraterone, enzalutamide, or docetaxel. RESULTS Between 2015-2020, we attended 26 prostate cancer patients (median age 69.5 years, range 52-84) with simultaneous oligometastases [mean 2.1 metastases, median 1.5 metastases (range 1-6)]. Eighteen patients (69%) presented lymph node metastases, 4 (15.5%) bone metastases and 4 (15.5%) both lymph node and bone metastases. With a median follow-up of 15.5 months (range 3-65 months), 16 patients (62%) are alive and tumor free while 10 (38%) are alive with tumor. Four patients (17%) developed tumor progression, out of irradiated area in all cases, with a median time to progression of 43.5 months (range 27-56 months). Actuarial progression-free survival (PFS) rates at 12 and 24 months were 94.1% and 84.7%, respectively. No grade > 2 acute or late complications were recorded. CONCLUSIONS Simultaneous directed radical hypofractionated radiation therapy for prostate and metastases is feasible, well tolerated and achieves an acceptable PFS rate. However, further studies with longer follow-up are necessary to definitively address these observations.

Abstract
PURPOSE A Gleason score ≥ 8, metastatic tumor burden, and visceral metastasis are known prognostic factors for patients with metastatic hormone-sensitive prostate cancer (mHSPC). Notably, however, these indicators have not been fully validated internationally. We aimed in this present study to further analyze the factors that influence the prognosis of mHSPC. METHODS In this retrospective study, we identified 201 patients with newly diagnosed mHSPC between 2008 and 2014 and collected their clinical information. Cox proportional hazard regression models were used to identify prognostic factors in mHSPC. RESULTS The mean age of the patients at presentation was 70 years (interquartile range (IQR), 64-76 years). The prostate-specific antigen level was 141 ng/mL (IQR, 58.8-464.5 ng/mL). Of the 201 study patients, 191 (94.5%) and 131 (65.2%) cases had a biopsy Gleason score ≥ 8 and grade 5, respectively. More than 4 metastases were detected in 134 patients. Castration-resistant prostate cancer (CRPC) was evident in 160 cases after a mean follow-up period of 46.6 months. By multivariable analysis, a Gleason grade of 5 and bone metastasis lesion count ≥ 4 were found to be significantly associated with CRPC-free survival (hazard ratio (HR), 1.45; 95% confidence interval (CI), 1.01-2.07) and (HR 2.02; 95% CI 1.39-2.92) and overall survival (HR 1.67 95%; CI 1.16-2.42) and (HR 1.67 95%; CI 1.16-2.41). CONCLUSIONS Bone metastases ≥ 4 and a Gleason grade 5 are independent prognostic factors for CRPC-free and overall survival in mHSPC. A Gleason grade 5 is therefore a new prognostic indicator in mHSPC.

Am J Mens Health 2021; 15:15579883211026515. [PMID: 34167355 PMCID: PMC8246524 DOI: 10.1177/15579883211026515] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2021] [Revised: 05/27/2021] [Accepted: 05/31/2021] [Indexed: 11/15/2022] Open
Abstract
OBJECTIVE To investigate the nonlinear relationship between age and the likelihood of undergoing prostate-specific antigen (PSA) testing, and the difference of factors influencing the test likelihood among subjects aged 40-54, 55-69, and ≥70 years. METHODS Data were extracted from the 2018 Behavioral Risk Factor Surveillance System, with the primary outcome defined as receipt of a PSA test within the previous 12 months. Restricted cubic splines were used to assess the relationship between age and the likelihood of undergoing PSA testing. Backward conditional logistic regression analyses were used to identify the predictors of undergoing PSA testing among subjects aged 40-54, 55-69, and ≥70 years. RESULTS Finally, 92,177 people were identified. The likelihood of PSA testing increased up to around 71 years old and then decreased rapidly for higher ages, showing a clear nonlinear inverted U-shaped relationship with age (p < .001). Insurance status, shared decision-making, whether a recommendation for PSA testing had been accepted, income level, smoking status, and age were the common predictors of testing in the three age groups. However, the predictors differed somewhat among the three groups: being overweight or obese was only positively associated with increased testing among people aged 40-54 and ≥70 years, being retired only greatly impacted the test likelihood among those aged 40-54 years, and the general health status, marital status, and race affected people aged ≥55 years. CONCLUSION The factors influencing PSA screening differ with age, which should be fully considered when screening different target age groups.

Abstract
This paper reports on a feasibility study of electrochemical in-vitro detection of prostate cancer biomarker PCA3 (prostate cancer antigen 3) in direct assay with specific RNA aptamer labelled with a redox group (ferrocene) and immobilized on a screen-printed gold electrode surface. The cyclic voltammograms and electrochemical impedance spectroscopy methods yield encouraging results on the detection of PCA3 in a range of concentrations from 1 μg/mL down to 0.1 ng/mL in buffer solutions. Both anodic and cathodic current values in cyclic voltammograms measurements and charge transfer resistance values in electrochemical impedance spectroscopy experiments correlate with the PCA3 concentration in the sample. Kinetics studies of the binding of the PCA3 to our aptamer demonstrated high specificity of the reaction with a characteristic affinity constant of approximately 4·10−10 molar. The results of this work provide a background for the future development of novel, highly sensitive and cost-effective diagnostic methodologies for prostate cancer detection.

Abstract
BACKGROUND Trials of cancer screening present results in terms of deaths prevented, but metastasis is also a key endpoint that screening seeks to prevent. We developed a framework for projecting overall (de novo and progressive) metastases prevented in a screening trial using prostate cancer screening as a case study. METHODS Mechanistic simulation model in which screening shifts a fraction of cases that would be metastatic at diagnosis to being non-metastatic. This shift increases the incidence of non-overdiagnosed, organ-confined cases. We use estimates of the risk of metastatic progression for these cases to project how many progress to metastasis after diagnosis and tally the projected de novo and progressive metastatic cases with and without screening. We use data on stage shift from the European Randomized Study of Screening for Prostate Cancer (ERSPC) and data on the risk of metastatic progression from the Scandinavian Prostate Cancer Group-4 trial. We estimate the relative risk and absolute risk reductions in metastatic disease at diagnosis and compare these with reductions in overall metastases. RESULTS Assuming no effect of screening beyond initial stage shift at diagnosis, the model projects a 43% reduction in metastasis at diagnosis but a 22% reduction in the cumulative probability of metastasis over 12 years in favor of screening. These results are consistent with the empirical findings from the ERSPC. CONCLUSION Any reduction in metastatic disease at diagnosis under screening is likely to be an overly optimistic predictor of the impact of screening on overall metastasis and disease-specific mortality.

Abstract
BACKGROUND Europa Uomo initiated the Europa Uomo Patient Reported Outcome Study (EUPROMS) to collect prostate cancer (PCa) patient-reported outcome (PRO) data as a primary endpoint. OBJECTIVE To inform future PCa patients about the impact of PCa treatment through self-reported PRO data of fellow patients collected outside a clinical trial setting. DESIGN, SETTING, AND PARTICIPANTS A cross-sectional survey was conducted among PCa patients currently receiving or having received treatment. The EUPROMS survey contained the EQ-5D-5 L (generic health), the EORTC-QLQ-C30 (cancer-specific quality of life (QoL), and the Expanded Prostate cancer Index Composite short form 26 (EPIC-26; prostate-specific health) questionnaires. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Descriptive statistics were used to assess the demographic and clinical characteristics, and to analyze the PROs of EQ-5D-5L, EORTC-QLQ-C30, and EPIC-26. RESULTS AND LIMITATIONS Between August 21 and November 19, 2019, 2943 men from 24 European countries completed the EUPROMS survey. The median age of the respondents was 71 yr (interquartile range 65-75 yr); 81.9% was living with a spouse. In total, 1937 (65.8%) men underwent a single treatment, and 636 (21.6%), 300 (10.2%), and 70 (2.4%) underwent two, three, and four treatments, respectively. Fatigue scores are highest for men who underwent radiotherapy or chemotherapy. Progression of disease leads to more insomnia. Surgery affects urinary incontinence the most. Self-reported sexual function amounts to 27/100, with the lowest scores being reported for men who underwent surgery and radiotherapy (15/100). Overall, patients who received two or more treatments reported lower scores for all indices. CONCLUSIONS The EUPROMS survey provided a cross-sectional picture of the current PCa patient population and their reported QoL. Initial treatment is often followed by subsequent treatments, affecting mainly sexual function, as well as fatigue and insomnia. QoL of men undergoing chemotherapy is worse for almost all domains. These data can inform physicians and patients on the true impact of PCa treatment. PATIENT SUMMARY Patient-reported quality of life in the Europa Uomo Patient Reported Outcome Study (EUPROMS) survey-a more informal setting as compared with clinical trials-reveals that prostate cancer treatment affects mainly sexual function, fatigue, and insomnia.

Abstract
Background Prostate-specific antigen (PSA) remains as the most used biomarker in the detection of early prostate cancer (PCa). Clinical practice guidelines (CPGs) are produced to facilitate incorporation of evidence into clinical practice. This is particularly useful when PCa screening remains controversial and guidelines diverge among different medical institutions, although opportunistic screening is not recommended. Methods We performed a systematic review of guidelines about PCa screening using PSA. Guidelines published since 2008 were included in this study. The most updated version of these CPGs was used for the evaluation. Results Twenty-two guidelines were selected for review. In 59% of these guidelines, recommendations were graded according to level of evidence (n = 13), but only 18% of the guidelines provided clear algorithms (n = 4). Each CPG was assessed using a checklist of laboratory issues, including pre-analytical, analytical, and post-analytical factors. We found that laboratory medicine specialists participate in 9% of the guidelines reviewed (n = 2) and laboratory issues were frequently omitted. We remarked that information concerning the consequences of World Health Organization (WHO) standard in PSA testing was considered by only two of 22 CPGs evaluated in this study. Conclusions We concluded that the quality of PCa early detection guidelines could be improved properly considering the laboratory issues in their development.

Abstract
The prognostic value of human leukocyte antigen (HLA) class I molecules in prostate cancer (PCa) remains unclear. Herein, we investigated the prognostic relevance of the most frequently expressed HLA-A alleles in Greece (A*02:01 and HLA-A*24:02) in de novo metastatic hormone-sensitive PCa (mPCa), which is a rare and aggressive disease characterized by a rapid progression to castration-resistance (CR) and poor overall survival (OS), contributing to almost 50% of PCa-related deaths. We identified 56 patients who had either progressed to CR (these patients were retrospectively analyzed for the time to the progression of CR and prospectively for OS) or had at least three months’ follow-up postdiagnosis without CR progression and, thus, were prospectively analyzed for both CR and OS. Patients expressing HLA-A*02:01 showed poor clinical outcomes vs. HLA-A*02:01−negative patients. HLA-A*24:02−positive patients progressed slower to CR and had increased OS. Homozygous HLA-A*02:01 patients progressed severely to CR, with very short OS. Multivariate analyses ascribed to both HLA alleles significant prognostic values for the time to progression (TTP) to CR and OS. The presence of HLA-A*02:01 and HLA-A*24:02 alleles in de novo mPCa patients are significantly and independently associated with unfavorable or favorable clinical outcomes, respectively, suggesting their possible prognostic relevance for treatment decision-making in the context of precision medicine.

Talala K, Heinävaara S, Taari K, Tammela TLJ, Kujala P, Stenman UH, Malila N, Auvinen A. Long-term health-related quality of life among men with prostate cancer in the Finnish randomized study of screening for prostate cancer. Cancer Med 2020; 9:5643-5654. [PMID: 32500650 PMCID: PMC7402814 DOI: 10.1002/cam4.3181] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2020] [Revised: 04/29/2020] [Accepted: 05/02/2020] [Indexed: 01/06/2023] Open
Abstract
Background The long‐term health‐related quality of life (HRQOL) impacts of PCa screening have not been adequately evaluated. We aimed to compare the generic and disease‐specific health‐related quality of life (HRQOL) among men with prostate cancer in the screening arm with the control arm of the PSA‐based prostate cancer screening trial in up to 15 years of follow‐up. Materials and methods This study was conducted within population‐based Finnish Randomized Study of Screening for Prostate Cancer (FinRSPC). During 1996‐1999 80,458 men were randomized to the serum prostate‐specific antigen (PSA) screening arm (SA, N = 32 000) and the control arm (CA, N = 48 458). Men in the screening arm were screened at 4‐year intervals until 2007. HRQOL questionnaires were delivered to newly diagnosed prostate cancer patients in the screening and control arm 1996‐2006 (N = 5128) at the time of diagnosis (baseline), at 3‐month, 12‐month and 5, 10, and 15‐year follow‐up. Validated UCLA Prostate Cancer Index (UCLA‐PCI) and RAND 36‐Item Health Survey were used for HRQOL assessment. The data were analyzed with a random effects model for repeated measures. Results At baseline, men with prostate cancer in the screening arm reported better Sexual Function, as well as less Sexual and Urinary Bother. Long‐term follow‐up revealed slightly higher HRQOL scores in the screening arm in prostate cancer specific measures at 10‐year post diagnosis, but the differences were statistically significant only in Urinary Bother (UCLA‐PCI score 77.9; 95% CI 75.2 to 80.5 vs. 70.9; 95% CI 66.8 to 74.9 P = .005). The generic HRQOL scores were comparable between the trial arms. The overall differences in disease‐specific or generic HRQOL scores by trial arm did not vary during the follow‐up. Conclusion No major differences were observed in HRQOL in men with prostate cancer between the prostate cancer screening and control arms during five to 15‐year follow‐up.

Abstract
For patients presenting with limited metastatic disease burden, known as the oligometastatic state of disease, a more aggressive treatment approach targeting the new or progressive metastatic lesions might improve patient outcome, with no or only limited toxicity to be expected from the treatment. This review provides an overview of the existing evidence and on-going trials on oligometastatic disease and metastasis-directed therapy in the field of renal, bladder and prostate cancer.

Cancer 2020; 126:3229-3236. [PMID: 32343403 DOI: 10.1002/cncr.32930] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2019] [Revised: 03/10/2020] [Accepted: 04/01/2020] [Indexed: 01/11/2023]
Abstract
BACKGROUND The objective of this study was to determine the effect of Medicaid expansion under the Patient Protection and Affordable Care Act (January 1, 2014) on the epidemiology of high-risk prostate-specific antigen (PSA) levels (≥20 ng/mL) at the time of prostate cancer (PCa) diagnosis. The authors hypothesized that better access to care would result in a reduction of high-risk features at diagnosis. METHODS A retrospective cohort study was performed of 122,324 men aged <65 years who were diagnosed with PCa within the National Cancer Database. Difference-in-difference (DID) analyses adjusting for sociodemographic variables using linear regression compared PSA levels at diagnosis before expansion (2012-2013) and after expansion (2015-2016) between men residing in states that did or did not expand Medicaid. RESULTS From 2012 to 2016, the proportion of men with PSA levels ≥20 ng/mL increased (from 18.9% to 19.8%) in nonexpansion states and decreased (from 19.9% to 18.2%) in expansion states. Compared with men in nonexpansion states, men in expansion states experienced a decline in PSA ≥20 ng/mL (DID, -2.33%; 95% CI, -3.21% to -1.44%; P < .001). Accordingly, the proportion of men presenting with high-risk disease decreased in expansion states relative to nonexpansion states (DID, -1.25%; 95% CI, -2.26% to 0.25%; P = .015). A similar statistically significant decrease in PSA levels ≥20 ng/mL was noted among black men (DID, -3.11%; 95% CI, -5.25% to 0.96%; P = .005). CONCLUSIONS In Medicaid expansion states, there was an associated decrease in the proportion of young men presenting with PSA ≥20 ng/mL at the time of PCa diagnosis. These results suggest that Medicaid expansion improved access to PCa screening. Longer term data should assess oncologic outcomes.

Oncologist 2020; 25:e1042-e1050. [PMID: 32190957 DOI: 10.1634/theoncologist.2019-0495] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2019] [Accepted: 02/18/2020] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND Germline DNA damage repair gene mutations (gDDRm) have been found in approximately 12% of patients with metastatic prostate cancer (mPCa). Previous studies of the clinical impact of gDDRm have mainly been in the setting of metastatic castration-resistant prostate cancer (mCRPC). This study aimed to determine the prognostic value of gDDRm in de novo metastatic and castration-sensitive prostate cancer (mCSPC). MATERIALS AND METHODS We retrospectively collected the records of 139 consecutive men with de novo mCSPC who initially received systemic therapies following guidelines. This included 128 patients who underwent genetic testing at our center and 11 patients referred to our center after being identified as gDDRm carriers. Time to mCRPC was collected. Kaplan-Meier and log-rank analysis were used to analyze the association between gDDRm and clinical outcomes. Survival outcomes were adjusted using multivariable Cox regression models. RESULTS Of the 139 patients with de novo mCSPC, 28 gDDRm carriers were identified. Median time progressing to mCRPC was significantly shorter in patients carrying gDDRm than in those without mutations (8.3 vs 13.2 months; hazard ratio [HR], 2.37; p < .001). Moreover, median progression time was almost halved in BRCA2 carriers (6.3 vs. 13.2 months; HR, 3.73; p < .001). Subgroup analysis revealed that the presence of gDDRm indicated poor therapy response regardless of disease volume and prostate-specific antigen nadir within the first 7 months. Presence of gDDRm remained independently associated with increased risk of progression to mCRPC in multivariate analysis (adjusted HR, 1.98; p = .006). CONCLUSION Our study suggested that positive gDDRm status predicted rapid progression to castration resistance in patients with de novo mCSPC. We propose identifying gDDRm status at the time of diagnosis for mCSPC patients, considering it is the first step of tailoring individualized treatment. In addition, DNA repair genes were a good therapeutic target for poly (ADP-ribose) polymerase inhibitors, and our results call for more frontline targeted therapy trials in gDDRm carriers to prolong the progression time. IMPLICATIONS FOR PRACTICE Results of this study suggested that positive germline DNA damage repair gene mutation (gDDRm) status predicted earlier progression to castration resistance in patients with de novo metastatic and castration-sensitive prostate cancer (mCSPC). These findings indicated the importance of intense therapy for some subgroups of mCSPC, especially for mCSPC harboring gDDRm with low-volume disease. Moreover, gDDRm was a good therapeutic target for poly (ADP-ribose) polymerase inhibitors, and these findings call for more molecular marker driven trials moving to the mTNPC setting.

Abstract
The value of the prostate-specific antigen (PSA) in prostate cancer (PCa) screening is controversial. Contradictory results have been reported in the literature as to whether PSA-based screening reduces mortality. Also, some of the studies published are methodologically flawed. However, evidence consistently demonstrates that screening programs results in the identification of patients with indolent prostatic tumors which rate has increased. Controversy is not only about the value of PSA-based screening, but also about the age range for screening, risk groups based on baseline PSA, PSA ranges, or the use of other biomarkers (PHI, 4Kscore). At present, PCa screening in the general population is not recommended by most scientific societies, although it can be used after discussing the risks and benefits with the patient. When discussing the need to perform a screening, the risks of using screening (lack of specificity of PSA, overdiagnosis) must be weighed against the risks of not performing it (increased rate of patients with initial diagnosis of metastasis). In the recent years, a number of authors have advocated the use of personalized screening, which could change the risk/benefit evaluation, thereby making screening necessary on the basis of a set of individual factors.

Abstract
The ALSYMPCA study established a 3.6 month Overall Survival (OS) benefit in metastatic Castration Resistant Prostate Cancer (mCRPC) patients treated with Radium-223 dichloride (Ra-223) over placebo. Here we report clinical outcomes of Ra-223 treatment in a nonstudy population. In this prospective registry, patients from 20 Dutch hospitals were included prior to Ra-223 treatment. Clinical parameters collected included previous treatments and Adverse Events. Primary outcome was 6 months Symptomatic Skeletal Event (SSE)-free survival, while secondary outcomes included Progression-Free Survival (PFS) and Overall Survival (OS). Of the 305 patients included, 300 were evaluable. The mean age was 73.6 years, 90% had ≥6 bone metastases and 74.1% were pretreated with Docetaxel, 19.5% with Cabazitaxel and 80.5% with Abiraterone and/or Enzalutamide. Of all patients, 96.7% were treated with Ra-223 and received a median of 5 cycles. After a median follow-up of 13.2 months, 6 months SSE-free survival rate was 83%, median PFS was 5.1 months and median OS was 15.2 months. Six months SSE-free survival rate and OS were comparable with those reported in ALSYMPCA. "Previous Cabazitaxel treatment" and "bone-only metastases" were independent predictors of a shorter and longer PFS, respectively, while above-median LDH and "bone-only metastases" were independent predictors of shorter and longer OS, respectively. Toxicity was similar as reported in the ALSYMPCA trial. These results suggest that in a nonstudy population, Ra-223 treatment is well-tolerated, equally effective as in the ALSYMPCA population and that patients not previously treated with Cabazitaxel benefit most from Ra-223.

Abstract
Androgen deprivation therapy as single modality therapy was the standard management for oligometastatic prostate cancer (PCa). Current paradigm shifts toward a multimodality therapy approach, targeting all sites of disease, including treatment of the primary in the form of radical prostatectomy or radiation therapy. The objective of this article was to reveiw the literature regarding the role of surgery in oligometastatic PCa. PubMed and MEDLINE electronic databases were queried for English language articles from January 1, 1980 to March 31, 2019. Keywords use included oligometastatic PCa, metastatic prostate cancer (mPCa), radical prostatectomy, and cytoreductive prostatectomy. Preclinical, prospective, and retrospective studies were included. There is no published randomized controlled trials, evaluating the role of surgery in mPCa. Preclinical and retrospective data suggest benefit of primary tumor treatment in mPCa. Current literature supports the concept of cytoreductive surgery as it can prevent late symptomatic local progression, has acceptable complications, and may prolong survival in patients with mPCa. Surgery is a feasible procedure in mPCa which may improve outcome in mPCa. However, there is no Level 1 evidence, yet that support the role of surgery in mPCa. The results from well-organized prospective, randomized controlled trials are awaited before performing radical prostatectomy for mPCa in clinical practice.

Abstract
BACKGROUND The CHAARTED and LATITUDE trials demonstrated improved outcomes with docetaxel or abiraterone plus androgen deprivation therapy in metastatic hormone sensitive prostate cancer (mHSPC) using two different prognostic scores. OBJECTIVE The aim of our study was to assess the concordance between the two scores and if these retained their prognostic value exclusively in de novo mHSPC. PATIENTS AND METHODS De novo mHSPC patients referring to our institution were retrospectively stratified according to the CHAARTED and LATITUDE classifications: high volume/high risk (HV/HR), low-volume/low-risk (LV/LR), and HVorHR (HV/LR and LV/HR). The Kaplan-Meier method and Cox proportional-hazard models were used to estimate hazard ratios for overall survival. RESULTS The study population included 106 patients. Concordance between the CHAARTED and LATITUDE classifications was observed in 86.8% of cases (65.1% HV/HR, 21.7% LV/LR), while 13.2% of patients fulfill the criteria of only one of the two classifications (HVorHR). When analyzed independently, the CHAARTED and LATITUDE classifications maintained their prognostic value (mOS 28.2 months in HV versus 60.9 months in LV, p = 0.006; 28.2 months in HR versus 40.6 months in LR, p = 0.017). The LR/LV population showed significantly longer mOS compared to the HR/HV group (72.6 months versus 26.3 months; p = 0.005), and to HVorHR patients (35.1 months; p = 0.003). No difference in OS was observed between HV/HR and HVorHR patients. ECOG PS ≥ 1 and patient age improved the prognostic value of the two classifications with multivariate analysis. CONCLUSIONS Our study showed a lack of complete concordance between the CHAARTED and LATITUDE classifications. The analysis confirmed the role of these prognostic scores to stratify de novo mHSPC patients in clinical practice.

Abstract
BACKGROUND The purpose of this study was to identify predictive factors associated with conditional net survival in patients with metastatic hormone-naive prostate cancer (mHNPC) initially treated with androgen deprivation therapy (ADT). METHODS At nine hospitals in Tohoku, Japan, the medical records of 605 consecutive patients with mHNPC who initially received ADT were retrospectively reviewed. The Pohar Perme estimator was used to calculate conditional net cancer-specific survival (CSS) and overall survival (OS) for up to 5 years subsequent to the diagnosis. Using multiple imputation, proportional hazard ratios for conditional CSS and OS were calculated with adjusted Cox regression models. RESULTS During a median follow up of 2.95 years, 208 patients died, of which 169 died due to progressive prostate cancer. At baseline, the 5-year CSS and OS rates were 65.5% and 58.2%, respectively. Conditional 5-year net CSS and OS survival gradually increased for all the patients. In patients given a 5-year survivorship, the conditional 5-year net CSS and OS rates improved to 0.906 and 0.811, respectively. Only the extent of disease score (EOD) ≥2 remained a prognostic factor for CSS and OS up to 5 years; as survival time increased, other variables were no longer independent prognostic factors. CONCLUSIONS The conditional 5-year net CSS and OS in patients with mHNPC gradually increased; thus, the risk of mortality decreased with increasing survival. The patient's risk profile changed over time. EOD remained an independent prognostic factor for CSS and OS after 5-year follow-up. Conditional net survival can play a role in clinical decision-making, providing intriguing information for cancer survivors.

Abstract
PURPOSE OF REVIEW To explore the current state of using prostate-specific membrane antigen (PSMA)-targeted PET imaging to aid in the diagnosis of clinically significant prostate cancer. RECENT FINDINGS Prostate-specific antigen screening remains controversial, as it is associated with the underdetection of clinically significant prostate cancer as well as the overdetection and subsequent overtreatment of clinically insignificant disease. A diagnostic test that can accurately assess the presence of clinically significant prostate cancer and avoid detection of low-risk tumors is needed. Multiparametric magnetic resonance imaging (mpMRI) can aid in the detection of clinically significant prostate cancer and can be used with fusion-based biopsy platforms to target biopsies to specific lesions. However, there are several limitations of mpMRI including a modest negative predictive value for high-grade cancer. PSMA-targeted PET imaging has shown promise as a noninvasive test to aid in the detection of clinically significant prostate cancer while providing anatomical information to guide targeted biopsies. PSMA-targeted PET in combination with mpMRI offers a higher degree of diagnostic accuracy for imaging localized prostate cancer than either modality alone. SUMMARY PSMA-targeted PET imaging can aid in the identification of men with clinically significant prostate cancer. Further research is needed to determine the full potential of PSMA-targeted imaging in both the detection and treatment of localized prostate cancer.

Abstract
Therapy resistance is a significant challenge for prostate cancer treatment in clinic. Although targeted therapies such as androgen deprivation and androgen receptor (AR) inhibition are effective initially, tumor cells eventually evade these strategies through multiple mechanisms. Lineage reprogramming in response to hormone therapy represents a key mechanism that is increasingly observed. The studies in this area have revealed specific combinations of alterations present in adenocarcinomas that provide cells with the ability to transdifferentiate and perpetuate AR-independent tumor growth after androgen-based therapies. Interestingly, several master regulators have been identified that drive plasticity, some of which also play key roles during development and differentiation of the cell lineages in the normal prostate. Thus, further study of each AR-independent tumor type and understanding underlying mechanisms are warranted to develop combinational therapies that combat lineage plasticity in prostate cancer.

Abstract
Purpose: To investigate the implications of the introduction of two hormonal therapies, abiraterone acetate + prednisone (AA+P) and enzalutamide (ENZA), for the treatment of naïve patients with metastatic castration-resistant prostate cancer (mCRPC) in the Italian setting. Methods: In 2017–2018, a Health Technology Assessment was conducted in Italy, considering the National Healthcare Service (NHS) perspective. Data were retrieved from literature evidence, economic evaluations, and qualitative questionnaires, considering the 9 EUnetHTA dimensions, and a final multi-criteria approach. Results: On the basis of mCRPC prevalence and incidence rates in Italy, the analysis considered 11,212 males eligible to either AA+P or ENZA treatments. Both drugs led to an improvement of the patients' overall survival, with respect to the standard of care, composed of docetaxel chemotherapy. However, AA+P showed a higher rate of drug-related moderate adverse events and a monitoring activities incidence superior to ENZA (+70%, p-value=0.00), which led to a major resources absorption (€ 1,056.02 vs € 316.25, p-value=0.00), whereas ENZA showed a better cost-effectiveness average value (CEV: 54,586.12 vs 57,624.15). Economic savings ranging from 1.46% to 1.61% emerged for the NHS, as well as organizational advantages, with fewer minutes required for the mCRPC management (AA+P: 815 mins vs ENZA: 500 mins). According to experts’ perceptions, based on a 7-item Likert scale (ranging from −3 to +3), similar results emerged on ethical and social impact (ENZA: 1.35 vs AA+P: 1.48, p-value>0.05), and on legal dimension (ENZA: 0.67 vs AA+P: 0.67, p-value>0.05), since both drugs improved the patients’ quality of life and received approval for use. High-level perceptions related to ENZA adoption emerged with regard to equity (ENZA: 0.69 vs AA+P: 0.25, p-value<0.05), since it is cortisone-free. Multi-criteria approach analysis highlighted a higher score of ENZA than comparator (0.79 vs 0.60, p-value=0.00). Conclusion: The evidence-based information underlined the advantages of ENZA and AA+P treatments as therapeutic options for mCRPC patients. In the appraisal phase, the higher score than the comparator suggested ENZA as the preferred treatment for mCRPC.

Decision models for distinguishing between clinically insignificant and significant tumors in prostate cancer biopsies: an application of Bayes' Theorem to reduce costs and improve outcomes. Health Care Manag Sci 2019; 23:102-116.

Abstract
Prostate cancer is the second leading cause of death from cancer, behind lung cancer, for men in the U. S, with nearly 30,000 deaths per year. A key problem is the difficulty in distinguishing, after biopsy, between significant cancers that should be treated immediately and clinically insignificant tumors that should be monitored by active surveillance. Prostate cancer has been over-treated; a recent European randomized screening trial shows overtreatment rates of 40%. Overtreatment of insignificant tumors reduces quality of life, while delayed treatment of significant cancers increases the incidence of metastatic disease and death. We develop a decision analysis approach based on simulation and probability modeling. For a given prostate volume and number of biopsy needles, our rule is to treat if total length of cancer in needle cores exceeds c, the cutoff value, with active surveillance otherwise, provided pathology is favorable. We determine the optimal cutoff value, c*. There are two misclassification costs: treating a minimal tumor and not treating a small or medium tumor (large tumors were never misclassified in our simulations). Bayes' Theorem is used to predict the probabilities of minimal, small, medium, and large cancers given the total length of cancer found in biopsy cores. A 20 needle biopsy in conjunction with our new decision analysis approach significantly reduces the expected loss associated with a patient in our target population about to undergo a biopsy. Longer needles reduce expected loss. Increasing the number of biopsy cores from the current norm of 10-12 to about 20, in conjunction with our new decision model, should substantially improve the ability to distinguish minimal from significant prostate cancer by minimizing the expected loss from over-treating minimal tumors and delaying treatment of significant cancers.

Abstract
BACKGROUND Prognostic stratification is the cornerstone of management in nonmetastatic prostate cancer (PCa). However, existing prognostic models are inadequate-often using treatment outcomes rather than survival, stratifying by broad heterogeneous groups and using heavily treated cohorts. To address this unmet need, we developed an individualised prognostic model that contextualises PCa-specific mortality (PCSM) against other cause mortality, and estimates the impact of treatment on survival. METHODS AND FINDINGS Using records from the United Kingdom National Cancer Registration and Analysis Service (NCRAS), data were collated for 10,089 men diagnosed with nonmetastatic PCa between 2000 and 2010 in Eastern England. Median follow-up was 9.8 years with 3,829 deaths (1,202 PCa specific). Totals of 19.8%, 14.1%, 34.6%, and 31.5% of men underwent conservative management, prostatectomy, radiotherapy (RT), and androgen deprivation monotherapy, respectively. A total of 2,546 men diagnosed in Singapore over a similar time period represented an external validation cohort. Data were randomly split 70:30 into model development and validation cohorts. Fifteen-year PCSM and non-PCa mortality (NPCM) were explored using separate multivariable Cox models within a competing risks framework. Fractional polynomials (FPs) were utilised to fit continuous variables and baseline hazards. Model accuracy was assessed by discrimination and calibration using the Harrell C-index and chi-squared goodness of fit, respectively, within both validation cohorts. A multivariable model estimating individualised 10- and 15-year survival outcomes was constructed combining age, prostate-specific antigen (PSA), histological grade, biopsy core involvement, stage, and primary treatment, which were each independent prognostic factors for PCSM, and age and comorbidity, which were prognostic for NPCM. The model demonstrated good discrimination, with a C-index of 0.84 (95% CI: 0.82-0.86) and 0.84 (95% CI: 0.80-0.87) for 15-year PCSM in the UK and Singapore validation cohorts, respectively, comparing favourably to international risk-stratification criteria. Discrimination was maintained for overall mortality, with C-index 0.77 (95% CI: 0.75-0.78) and 0.76 (95% CI: 0.73-0.78). The model was well calibrated with no significant difference between predicted and observed PCa-specific (p = 0.19) or overall deaths (p = 0.43) in the UK cohort. Key study limitations were a relatively small external validation cohort, an inability to account for delayed changes to treatment beyond 12 months, and an absence of tumour-stage subclassifications. CONCLUSIONS 'PREDICT Prostate' is an individualised multivariable PCa prognostic model built from baseline diagnostic information and the first to our knowledge that models potential treatment benefits on overall survival. Prognostic power is high despite using only routinely collected clinicopathological information.

Creating a potential diagnostic for prostate cancer risk stratification (InformMDx™) by translating novel scientific discoveries concerning cAMP degrading phosphodiesterase-4D7 (PDE4D7). Clin Sci (Lond) 2019; 133:269-286.

Abstract
Abstract
Increased PSA-based screening for prostate cancer has resulted in a growing number of diagnosed cases. However, around half of these are ‘indolent’, neither metastasizing nor leading to disease specific death. Treating non-progressing tumours with invasive therapies is currently regarded as unnecessary over-treatment with patients being considered for conservative regimens, such as active surveillance (AS). However, this raises both compliance and protocol issues. Great clinical benefit could accrue from a biomarker able to predict long-term patient outcome accurately at the time of biopsy and initial diagnosis. Here we delineate the translation of a laboratory discovery through to the precision development of a clinically validated, novel prognostic biomarker assay (InformMDx™). This centres on determining transcript levels for phosphodiesterase-4D7 (PDE4D7), an enzyme that breaks down cyclic AMP, a signalling molecule intimately connected with proliferation and androgen receptor function. Quantifiable detection of PDE4D7 mRNA transcripts informs on the longitudinal outcome of post-surgical disease progression. The risk of post-surgical progression increases steeply for patients with very low ‘PDE4D7 scores’, while risk decreases markedly for those patients with very high ‘PDE4D7 scores’. Combining clinical risk variables, such as the Gleason or CAPRA (Cancer of the Prostate Risk Assessment) score, with the ‘PDE4D7 score’ further enhances the prognostic power of this personalized, precision assessment. Thus the ‘PDE4D7 score’ has the potential to define, more effectively, appropriate medical intervention/AS strategies for individual prostate cancer patients.

Abstract
BACKGROUND Several systemic therapeutic options exist for metastatic castrate-sensitive prostate cancer (mCSPC). Circulating tumor DNA (ctDNA) can molecularly profile metastatic castration-resistant prostate cancer and can influence decision-making, but remains untested in mCSPC. OBJECTIVE To determine ctDNA abundance at de novo mCSPC diagnosis and whether ctDNA provides complementary clinically relevant information to a prostate biopsy. DESIGN, SETTING, AND PARTICIPANTS We collected plasma cell-free DNA (cfDNA) from 53 patients newly diagnosed with mCSPC and, where possible, during treatment. Targeted sequencing was performed on cfDNA and DNA from diagnostic prostate tissue. RESULTS AND LIMITATIONS The median ctDNA fraction was 11% (range 0-84%) among untreated patients but was lower (1.0%, range 0-51%) among patients after short-term (median 22d) androgen deprivation therapy (ADT). TP53 mutations and DNA repair defects were identified in 47% and 21% of the cohort, respectively. The concordance for mutation detection in matched samples was 80%. Combined ctDNA and tissue analysis identified potential driver alterations in 94% of patients, whereas ctDNA or prostate biopsy alone was insufficient in 19 cases (36%). Limitations include the use of a narrow gene panel and undersampling of primary disease by prostate biopsy. CONCLUSIONS ctDNA provides additional information to a prostate biopsy in men with de novo mCSPC, but ADT rapidly reduces ctDNA availability. Primary tissue and ctDNA share relevant somatic alterations, suggesting that either is suitable for molecular subtyping in de novo mCSPC. The optimal approach for biomarker development should utilize both a tissue and liquid biopsy at diagnosis, as neither captures clinically relevant somatic alterations in all patients. PATIENT SUMMARY In men with advanced prostate cancer, tumor DNA shed into the bloodstream can be measured via a blood test. The information from this test provides complementary information to a prostate needle biopsy and could be used to guide management strategies. Sequencing data were deposited in the European Genome-phenome Archive (EGA) under study identifier EGAS00001003351.

Abstract
Although prostate cancer is one of the most common cancers in the male population, its basic biological function at a cellular level remains to be fully understood. This lack of in depth understanding of its physiology significantly hinders the development of new, targeted and more effective treatment strategies. Whilst electrophysiological studies can provide in depth analysis, the possibility of recording electrical activity in large populations of non-neuronal cells remains a significant challenge, even harder to address in the picoAmpere-range, which is typical of cellular level electrical activities. In this paper, we present the measurement and characterization of electrical activity of populations of prostate cancer cells PC-3, demonstrating for the first time a meaningful electrical pattern. The low noise system used comprises a multi-electrode array (MEA) with circular gold electrodes on silicon oxide substrates. The extracellular capacitive currents present two standard patterns: an asynchronous sporadic pattern and a synchronous quasi-periodic biphasic spike pattern. An amplitude of ±150 pA, a width between 50⁻300 ms and an inter-spike interval around 0.5 Hz characterize the quasi-periodic spikes. Our experiments using treatment of cells with Gd³⁺, known as an inhibitor for the Ca²⁺ exchanges, suggest that the quasi-periodic signals originate from Ca²⁺ channels. After adding the Gd³⁺ to a population of living PC-3 cells, their electrical activity considerably decreased; once the culture was washed, thus eliminating the Gd³⁺ containing medium and addition of fresh cellular growth medium, the PC-3 cells recovered their normal electrical activity. Cellular viability plots have been carried out, demonstrating that the PC-3 cells remain viable after the use of Gd³⁺, on the timescale of this experiment. Hence, this experimental work suggests that Ca²⁺ is significantly affecting the electrophysiological communication pattern among PC-3 cell populations. Our measuring platform opens up new avenues for real time and highly sensitive investigations of prostate cancer signalling pathways.

Abstract
Reasons for and against screening of prostate cancer have been discussed widely over the last decade. In 2014, the European Randomized Trial for Screening of Prostate Cancer (ERSPC) has reported a relative reduction of the cancer-specific survival of 27% in participants who definitely followed the screening protocol. This relative advantage has proven to be stable from year 7 to year 13 after the beginning of screening. Still, the disadvantages of overdiagnosis and overtreatment are the downsides of a population-based screening approach. But given the overall advantage of screening, a risk-adapted prostate-specific antigen (PSA) screening using a baseline PSA value at ages 45-50 may significantly reduce the number needed to diagnose maintaining the benefits of screening. PROBASE is a randomized risk-adapted screening trial currently ongoing in Germany to answer this important question.
