The real prevalence and clinical courses of non-metastatic castration-resistant prostate cancer: a retrospective single-institutional study.

Non-metastatic castration-resistant prostate cancer (PCa) has become clinically important in PCa management, with treatments aiming to delay metastasis. However, limited data exist on its prevalence and patient characteristics in real-world settings. We retrospectively investigated the clinical records of 1929 patients who were treated for localized PCa between 2005 and 2018. From this population, we counted patients who progressed to non-metastatic castration-resistant PCa, and summarized the characteristics of the patients. Among patients who underwent radical prostatectomy (796 patients), radiation therapy (1021 patients), or primary androgen deprivation therapy (ADT) (112 patients), 0.9%, 0.9%, and 5.4%, respectively, were diagnosed with non-metastatic castration-resistant PCa over a median follow-up of 5.5years. Including referred cases, a total of 45 non-metastatic castration-resistant PCa patients were analyzed. The median age at non-metastatic castration-resistant PCa diagnosis was 76years, with a median time of 4.8years from the initiation of ADT to non-metastatic castration-resistant PCa development. From the initial PCa diagnosis, the median time to non-metastatic castration-resistant PCa was 5.9years. Median metastasis-free survival was 5.2years, while overall survival was 6.3years. This study reports the prevalence of non-metastatic castration-resistant PCa at our institution and provides clinical findings of non-metastatic castration-resistant PCa patients by analyzing consecutive localized PCa cases through comprehensive medical chart reviews for every patient.

DNA Repair Capacity and Clinicopathological Characteristics in Puerto Rican Hispanic/Latino Patients with Metastatic Castration-Resistant Prostate Cancer

Background: Prostate cancer (PCa) accounts for 22% of the new cases diagnosed in Hispanic/Latino (H/L) men in the US. PCa has the highest incidence (38.3%) and mortality (16.4%) among all types of cancer diagnosed in Puerto Rico. We previously showed that PCa patients (n = 41) have a significant reduction of 59% in their levels of DNA repair capacity (DRC) when compared to controls (n = 14). This study aimed to evaluate DRC levels through the nucleotide excision repair (NER) pathway for the first time in 16 Puerto Rican H/L men with metastatic castration-resistant PCa (mCRPCa) while establishing comparisons with controls and PCa patients with indolent and aggressive disease. Methods: Blood samples and clinicopathological data from PCa cases (n = 71) and controls (n = 25) were evaluated. PCa cases were stratified into mCRPCa (n = 16), aggressive (n = 31), and indolent (n = 24). DRC levels through NER were measured in lymphocytes with the CometChip assay. The stratification by Gleason score (GS) was GS6 (n = 7), GS7 (n = 23), GS ≥ 8 (n = 20), and mCRPCa patients (n = 16). Results: Significant statistical differences were found when comparing the DRC values of the controls with any other of the four PCa patient groups. mCRPCa patients had the lowest mean DRC level of all four patient groups studied. The mean DRC level of mCRPCa patients was 6.65%, and compared to the controls, this represented a statistically significant reduction of 62% (p < 0.0001). Further analysis was performed to evaluate the contributions of age, anthropometric measurements, and prostate-specific antigen (PSA) levels to the DRC. Kaplan–Meier curves of mCRPCa revealed that survival probability decreased by approximately 50% by 30 months. This pilot study uses a blood-based phenotypic assay to present the first report of mCRPCa in Puerto Rican men and at a global level of DRC levels of mCRPCa patients. Conclusions: This study evaluated DRC levels through the NER pathway for the first time in 16 Puerto Rican H/L men with mCRPCa. Significant differences in DRC values were found between the controls and the three PCa patient groups. Kaplan–Meier curves revealed that survival probability decreased by approximately 50% by 30 months, and only 20% of the cohort was alive at 50 months, confirming the lethality of mCRPCa in this H/L population. This pilot study represents the first report of metastatic PCa in Puerto Rican men at a global level of DRC levels of mCRPCa patients using a blood-based phenotypic assay.

Vitamin D-related genetic variants and prostate cancer risk in Black men.

The relationship between vitamin D and prostate cancer has primarily been characterized among White men. Black men, however, have higher prostate cancer incidence and mortality rates, chronically low circulating vitamin D levels, and ancestry-specific genetic variants in vitamin D-related genes. Here, we examine critical genes in the vitamin D pathway and prostate cancer risk in Black men. We assessed a total of 73 candidate variants in genes (namely GC, CYP27A1, CYP27B1, CYP24A1, VDR, and RXRA) including functional variants previously associated with prostate cancer and circulating 25(OHD) in White men. Associations with prostate cancer risk were examined using genome-wide association study data for approximately 10,000 prostate cancer cases and 10,000 controls among Black men and over 85,000 cases and 91,000 controls among White men for comparison. A statistical significance threshold of 0.000685 was used to account for the 73 variants tested. None of the variants examined were significantly associated with prostate cancer risk among Black men after multiple comparison adjustment. Suggestive associations (P < 0.05) for four variants were found in Black men, including two in RXRA (rs41400444 OR=1.09, 95 % CI: 1.01-1.17, P = 0.024 and rs10881574 OR = 0.93, 0.87-1.00, P = 0.046) and two in VDR (rs2853563 OR = 1.07, 1.01-1.13, P = 0.017 and rs1156882 OR = 1.06, 1.00-1.12, P = 0.045). Two variants in VDR were also positively associated with risk in White men (rs11568820 OR = 1.04, 1.02-1.06, P = 0.00024 and rs4516035 OR = 1.03, 1.01-1.04, P = 0.00055). We observed suggestive associations between genetic variants in RXRA and VDR and prostate cancer risk in Black men. Future research exploring the relationship of vitamin D with cancer risk in Black men will need larger sample sizes to identify ancestry-specific variants relevant to risk in this population.

Intermediate risk prostate tumors contain lethal subtypes

In 2024, prostate cancer (PCa) remains the most common non-skin cancer in males within the United States, with an estimated 299,010 new cases, the highest increase incident trend rate (3.8%) of all cancers, and one of the eight deadliest. PCa cases are projected to double from 1.8 million to 2.9 million per year between 2020 and 2040. According to the National Comprehensive Cancer Network (NCCN) treatment guidelines, most cases (65%) are intermediate risk (Gleason sum score &amp;lt;7 [3 + 4, 4 + 3], prostate organ-confined, and PSA &amp;lt; 20) with treatment options limited to active surveillance, external beam radiation, and/or surgery to prevent metastasis in the long term (&amp;gt;10 years). It is increasingly recognized that the two most common subtypes of intermediate risk PCa are cribriform architecture (CA) and intraductal carcinoma of the prostate (IDC-P), which can occur together, and both are associated with increased metastatic risk, biochemical recurrence, and disease-specific mortality. Both subtypes display hypoxia, genomic instability, and are identified as Gleason 4 in pathology reports. However, since false negatives are common (up to 50%) in these subtypes on biopsy, more research is needed to reliably detect these subtypes that have an increased risk for invasive disease. We note that even with mpMRI-guided biopsies, the sensitivity is 54% for cribriform architecture and only 37% for IDC-P. The presence of these PCa subtypes in biopsy or radical prostatectomy (RP) tissue can exclude patients from active surveillance and from designation as intermediate risk disease, further underscoring the need for increased molecular understanding of these subtypes for diagnostic purposes. Understanding the heterogeneity of intermediate risk primary PCa phenotypes, using computational pathology approaches to evaluate the fixed biopsy specimen, or video microscopy of the surgical specimen with AI-driven analysis is now achievable. New research associating the resulting phenotypes with the different therapeutic choices and vulnerabilities will likely prevent extracapsular extension, the definition of high-risk disease, and upstaging of the final pathologic stage.

Gut microbiota, metabolites, and cytokines in relation to the risk of prostate cancer in the Asian population

PurposeStudies have shown that gut microbiota is involved in the tumorigenesis and development of prostate cancer. We aimed to perform a comprehensive analysis of causal associations of gut microbiota, metabolites, and cytokines with prostate cancer in the Asian population.Patients and methodsGenome-wide association study (GWAS) summary datasets were collected from the public databases. There were 418 bacterial traits, 452 metabolites, 91 cytokines, 5408 cases of prostate cancer from East Asia, and 109,347 controls included. Mendelian randomization (MR) analyses were performed to investigate their causal relationships. Sensitivity analyses were conducted to test the reliability of MR results. Furthermore, the FinnGen database was used to assess the generalizability of our findings based on Asians.ResultsThere were a total of 17 bacterial traits, 28 metabolites (including 2 microbiota-associated metabolites), and 9 cytokines to be significantly associated with prostate cancer in Asians (P &amp;lt; 0.05). Further MR analyses of these positive results indicated that G_Ruminococcaceae UCG014/TNFSF10 axis, G_Anaerofilum/TNFRSF14 axis, G_Erysipelotrichaceae UCG003/TNFSF10 axis, and P_Proteobacteria/cholesterol axis were key signaling pathways involved in the progression of prostate cancer. Notably, G_Ruminococcaceae UCG014/TNFSF10 axis and G_Anaerofilum/TNFRSF14 axis were found to act as protective factors, while the other two signaling axes played a crucial role in promoting the progression of prostate cancer. Sensitivity analyses further confirmed the reliability of our findings. Using the European population as outcome, we further assessed the generalizability of our conclusions and found limited applicability to Europeans.ConclusionsWe found that there were causal associations of gut microbiota, metabolites, and cytokines with prostate cancer in Asians. The causal effects of gut microbiota on prostate cancer were partially mediated by metabolites and cytokines. These findings might contribute to the development of new therapeutic strategies for prostate cancer.

Incidence, trends and patterns of female breast, cervical, colorectal and prostate cancers in Antigua and Barbuda, 2017–2021: a retrospective study

BackgroundGlobally, estimates of cancer cases and deaths have increased since 2018, particularly in Latin America and Caribbean countries. In Antigua and Barbuda, understanding the burden of common cancers such as female breast, cervical, colorectal and prostate cancers is critical. This study aimed to assess the incidence, trends, and patterns of these four cancers from 2017 to 2021.MethodsUsing a retrospective observational study design, information on these cancers was abstracted from medical records at four key study sites in Antigua and Barbuda. Estimates of age-specific and age-standardized incidence were determined using direct standardization. The KeyFitz method was used to derive standard errors and confidence intervals. Derived estimates were employed to analyze trends and Joinpoint regression modeling was used to determine annual percentage change.ResultsBetween 2017 and 2021, 391 cases of female breast (41.7%), cervical (10.2%), colorectal (20.2%) and prostate (27.9%) cancers were diagnosed. Overall mean age at presentation was 61.5 (± 12.9) years, ranging from 24 to 94 years, age-standardized incidence rate 65.2 (95% CI: 58.7–71.6) per 100,000 population. Age-standardized incidence rate for female breast cancer was 49.9 (95% CI: 42.2–57.8), annual percentage change in incidence a low of -0.2%. Prostate cancer had the second highest age-standardized incidence rate at 41.6 (95% CI: 33.8–49.4), annual percentage change showed a gradual but steady increase at 21.7%. Per cancer types, variations in age-standardized incidence rates were noted across age-groups, year-of-presentation, and parishes. Collectively, there was an 8.1% (95% CI: -14.9–37.6) annual percentage change increase in age-standardized incidence rates between 2017 and 2021. Incident cases, age-standardized incidence rates, and trends per cancer type are expected to gradually increase during 2022–2030 (average annual percentage increase is 3.4%).ConclusionsThis study is a first step in providing reasonable evidence on the incidence, trends, and patterns of four common cancers in Antigua and Barbuda. Female breast and prostate cancers were the dominant cancer types in terms of incidence, age-standardized incidence and predicted increasing incidence trends. Variableness in cancer-specific age-standardized rates across parishes and years of presentation were observed. Besides research, this study has importance for instituting cancer prevention and control measures, including surveillance and healthy lifestyles initiatives.

Fusion MRI/Ultrasound-Guided Transperineal Biopsy: A Game Changer in Prostate Cancer Diagnosis

Background/Objectives: Multiparametric-Magnetic Resonance Imaging(mp-MRI) presents the ability to detect clinically significant cancer, aiming to avoid biopsy if the results are negative or target an abnormal lesion if a suspected lesion of the prostate is found. Recent guidelines recommend the performance of 12 standard biopsies along with 3 to 5 targeted biopsies in suspected prostate lesions, depending on the size of the prostate lesion. In addition, prostate biopsy can be performed by either the transperineal or the transrectal approach. The aim of this comprehensive review is to highlight the role of both standard and targeted MRI/Ultrasound (US) fusion transperineal biopsy (TPB) in the diagnostic approach of prostate cancer cases, to report its diagnostic efficacy and complication rates and to suggest the promising usage of MRI/US fusion TPB in the future. Methods: A comprehensive review of the existing literature, including systematic reviews, meta-analyses, and clinical guidelines, was conducted to compare the efficacy and safety of transperineal and transrectal approaches in prostate cancer detection. Special emphasis was placed on mp-MRI-guided targeted biopsy and its combination with systematic sampling. Results: Prostate biopsy via the transperineal approach is related to increased detection rates, especially for anterior lesions, and decreased infection risk compared to the transrectal approach, while complication rates (hematuria, hemospermia, etc.) remain similar. Due to lower infection rates via the transperineal route, the performance of prostate biopsy using the transperineal approach is strongly recommended. Finally, transperineal fusion MRI/US biopsy can be valuable for repeat biopsies in patients who had an initial negative biopsy or for the follow-up of patients that undergo active surveillance. Conclusions: MRI/US fusion-guided TPB represents a significant advancement in prostate cancer diagnostics, combining improved precision with reduced infection risks. Although TPB presents higher detection rates for anterior prostatic lesions and lower post-biopsy infection rates, there is no significant difference in cancer detection rates compared to TRB. Targeted training and investment may reduce long-term expenses of TPB by lowering hospitalizations, antibiotic usage, and related costs. Future research should further refine this approach and explore its integration with emerging technologies like artificial intelligence for enhanced lesion targeting and diagnostic accuracy.

Exploring the link between sex hormone-binding globulin levels and prostate cancer risk: a comprehensive systematic review and meta-analysis.

Sex hormone-binding globulin (SHBG) plays a critical role in regulating androgen bioavailability and has been hypothesized to influence prostate cancer risk, though existing evidence is inconsistent. This systematic review and meta-analysis aimed to evaluate the association between SHBG levels and prostate cancer risk. A comprehensive search was conducted across PubMed, Embase, and Web of Science for studies published up to December 1, 2024. Observational studies assessing SHBG levels and prostate cancer risk were included. Effect sizes were pooled using random-effects meta-analysis. Heterogeneity was evaluated using the I2 statistic, and quality assessment was performed using the Newcastle-Ottawa Scale. Statistical analysis was performed using R software version 4.4. Sixteen studies, including 720,298 participants and 90,799 prostate cancer cases, were analyzed. The pooled odds ratio (OR) for prostate cancer risk per unit increase in SHBG was 0.907 (95% CI 0.799-1.030), indicating no statistically significant association. Substantial heterogeneity was observed among the included studies (I2 = 79%; P < 0.0001). Subgroup analyses showed no significant variation in effect sizes by study design. However, a Mendelian randomization analysis conducted in 140,254 European-descent males, including 79,148 prostate cancer cases, suggested a modest protective effect of higher SHBG levels, with an OR of 0.944 (95% CI 0.897-0.993). Sensitivity analyses confirmed the robustness of the pooled findings. This meta-analysis showed a complex relationship between SHBG levels and prostate cancer risk. While overall findings do not support a statistically significant association, higher SHBG levels may confer a protective role in specific contexts. Further research is needed to elucidate mechanisms, reduce heterogeneity, and validate SHBG as a biomarker for risk stratification.

PI-RADS 3 MRI lesions: Are biopsies still necessary?

A significant proportion of newly diagnosed prostate cancer (PCa) cases are slow growing with a low risk of metastatic progression. There is a lack of data concerning the optimal biopsy regimen for improving diagnosis yield in PI-RADS3 lesions. This study aimed to assess the diagnostic value of current biopsy regimens in PI-RADS 3 lesions and identify clinical predictors to improve clinically significant PCa (csPCa) detection. This retrospective study included patients from two academic centers between 2017 and 2024 who benefitted from prostate biopsies for a PI-RADS 3 lesion. Prostate biopsies were performed via either a transrectal or a transperineal route according to local resources. All patients underwent systematic and targeted cores. Targeted biopsies were performed using MRI-ultrasound fusion software or cognitive fusion. Patients were categorized based on biopsy results: benign, clinically insignificant (insignPCa, i.e. ISUP 1), or csPCa (ISUP≥2). The primary endpoint was to assess the detection rate of csPCa in MRI-targeted biopsies alone and in MRI-targeted+ipsilateral systematic cores in comparison to the gold standard MRI-targeted+systematic biopsies. Then, the percentage of csPCa missed and insignPCa diagnoses avoided were calculated referring to the gold standard MRI-targeted+systematic template. A total of 163 men with at least one PI-RADS 3 index lesion were identified. Ninety-one (55.8%) lesions were benign, 52 (32%) were insignPCa and 20 (12.3%) were csPCa. Of the 20 patients with csPCa, the diagnosis was made with targeted cores in 12 patients and with systematic cores in 8 patients. If no biopsies were performed, 12.3% of csPCa would have gone undiagnosed. Targeted biopsies alone would have missed 4.9% of csPCa but avoided 24.5% of insignPCa. Targeted biopsies with systematic cores solely performed on the same side as the index lesion would have missed 3.8% of csPCa and avoided 12.9% of insignPCa. We reported no significant differences in detection rate of csPCa between MRI-targeted cores alone vs. the gold standard template (7.4% vs. 12.3%; P=0.9) and between MRI-targeted cores+ipsilateral systematic cores vs. the gold standard template (8.5% vs. 12.3%; P=1.2). At multivariable analysis age, clinical T stage, and mpMRI lesion size were predictors of csPCa. As a small proportion of PI-RADS 3 lesions are associated with csPCa, the value of biopsies is questionable. Targeted biopsies with systematic cores on the same side as the index lesion may improve detection of csPCa and reduce overdiagnosis of indolent CaP. Clinical T stage and lesion size on MRI can potentially predict the presence of clinically significant CaP.

Kidney and gallbladder stones and the risk of prostate cancer: Results from the EPICAP study.

Prostate cancer remains the most frequent cancer among men, representing a significant health burden. Despite its high morbidity and mortality rates, the etiology of prostate cancer remains relatively unknown, with only non-modifiable established risk factors. Chronic inflammation has emerged as a potential factor in prostate carcinogenesis. We investigated the role of kidney and gallbladder stones and the risk of prostate cancer. We used data from EPICAP, a population-based case-control study. A total of 819 diagnosed prostate cancer cases and 879 controls were face-to-face interviewed using a standardized questionnaire that collected information on personal medical history, including history of kidney and gallbladder stones. Odds Ratios (OR) and their 95% confidence interval (CI) were estimated using multivariate unconditional logistic regression. Our study revealed intriguing patterns regarding kidney and gallbladder stones in relation to prostate cancer risk. The analysis indicated significant potential associations between kidney stones and the risk of prostate cancer (OR: 1.46 95% CI: 1.13-1.90), particularly in men with a history of kidney infection. Additionally, our data suggested a possible relationship between gallbladder stones and prostate cancer when considering triglyceride (OR: 2.27, 95% CI: 0.99-5.28), although further research is needed for a conclusive understanding. Our results suggest an association between calculi and the risk of prostate cancer. Findings from this study underscore the need for a more comprehensive investigation to understand the role of chronic inflammation or metabolism and delineate the mechanisms underlying these potential associations in order to guide the development of targeted preventive strategies for aggressive prostate cancer.

Application of Original Prostate Cancer Progression Model Interacting with Fibroblasts in Preclinical Research.

Prostate cancer (PCa) is a heterogeneous disease that exhibits androgen sensitivity and responsiveness to androgen deprivation therapy (ADT). However, ADT induces only temporary remission, and the majority of PCa cases eventually progress to castration-resistant PCa (CRPC). During the development and progression of CRPC, androgen sensitivity and androgen receptor (AR) dependency in PCa cells are often deceased or lost due to ADT or spontaneously arising AR variants even before starting ADT. To prevent CRPC, a clinical PCa model derived from an AR-positive cancer cell line with weak or no androgen sensitivity is required. The human prostate LNCaP cell line is a good model for PCa because of its androgen sensitivity and AR dependency in terms of cell growth and gene expression. Notably, LNCaP cells are heterogeneous cells comprising different clones with natural variations in androgen sensitivity and AR dependency resulting from spontaneously occurring changes. In our group, to obtain androgen-insensitive or weakly sensitive clones spontaneously derived from parental LNCaP cells, we performed a limiting dilution of parental LNCaP cells and obtained several sublines with varying levels of androgen sensitivity and AR dependency. In addition, we established an androgen-insensitive subline from parental LNCaP cells by continuous passage under hormone-depleted conditions. This article provides a unique perspective on our original PCa progression model interacting with fibroblasts and its application in preclinical research.

Exploring the role of pomalidomide in androgen-dependent prostate cancer: a computational analysis.

Prostate cancer (PC) is among the most prevalent cancers in males. It is the leading cause of death in men, in around 48 out of 185 countries. Increased androgen receptor (AR) activity is the key factor contributing to the development or progression of newly diagnosed cases of prostate cancer. Over time, numerous compounds targeting AR have been identified, presenting encouraging avenues for suppressing its hyperactivity. In our investigation, we used the GEPIA tool to study the importance of AR in the context of prostate cancer. This tool integrates the data from TCGA and GTEx in the gene expression pattern analysis and their clinical relevance. This analysis evaluates overall survival, disease-free survival, and transcripts per million (TPM) analysis of AR in PC. We performed docking and simulation for FDA-approved anticancer drugs to assess their potential interactions with the AR. We also conducted a comprehensive analysis of drugs using a quantum calculation (DFT) which provides electronic properties, chemical reactivity, and stability using the HOMO-LUMO energy gap. This study suggests that repurposed synthetic anticancer drugs could be better options for treating prostate cancer by inhibiting AR. In this work, we have shown the potential of pomalidomide, a synthetic anticancer drug, as a potential candidate for androgen-dependent PC treatment.

Machine learning algorithms that predict the risk of prostate cancer based on metabolic syndrome and sociodemographic characteristics: a prospective cohort study

BackgroundGiven the rapid increase in the prevalence of prostate cancer (PCa), identifying its risk factors and developing suitable risk prediction models has important implications for public health. We used machine learning (ML) approach to screen participants with high risk of PCa and, specifically, investigated whether participants with metabolic syndrome (MetS) exhibited an elevated PCa risk.MethodsA prospective cohort study was performed with 41,837 participants in South Korea. We predicted PCa based on MetS, its components, and sociodemographic factors using Cox proportional hazards and five ML models. Integrated Brier score (IBS) and C-index were used to assess model performance.ResultsA total of 210 incident PCa cases were identified. We found good calibration and discrimination for all models (C-index ≥ 0.800 and IBS = 0.01). Importantly, performance increased after excluding MetS and its components from the models; the highest C-index was 0.862 for survival support vector machine. In contrast, first-degree family history of PCa, alcohol consumption, age, and income were valuable for PCa prediction.ConclusionML models are an effective approach to develop prediction models for survival analysis. Furthermore, MetS and its components do not seem to influence PCa susceptibility, in contrast to first-degree family history of PCa, age, alcohol consumption, and income.

Radical prostatectomy outcomes of prostate cancer cases: Insights from a leading surgeon's experience in Azerbaijan.

Prostate cancer is a significant health concern worldwide and ranks as the 4th most frequent cancer among men in Azerbaijan. While robot-assisted laparoscopic radical prostatectomy is the preferred surgical technique in many countries, open retropubic radical prostatectomy (ORP) remains the primary treatment option in Azerbaijan due to limited access to robotic surgical systems. This study aims to analyze the outcomes of ORP in patients with local and locally advanced prostate cancer. We retrospectively evaluated 95 men who underwent extraperitoneal retropubic ORP for prostate cancer at our center between May 2020 and December 2023. Comprehensive data on patient demographics, preoperative parameters, surgical details, and postoperative outcomes were collected. Statistical analyses were conducted using IBM SPSS 27.0 software. The mean age of the patients was 65.9 years. The median preoperative PSA level was 14.8 ng/mL, and lymph node enlargement was identified in 29.5% of patients. A rectal injury occurred in one patient (1.1%) as the only intraoperative complication. The mean intraoperative blood loss was 330 mL, and the median hospital stay was 6 days. A positive surgical margin was observed in 38.9% of cases. Diabetes mellitus and higher intraoperative blood loss were associated with prolonged hospital stays (≥ 7 days). Erectile dysfunction was reported in 52.6% of patients 6 months postoperatively, while urinary incontinence was observed in 2.2%. ORP outcomes in Azerbaijan are comparable to those reported for laparoscopic and robot-assisted techniques in terms of perioperative and oncological results. Despite the absence of advanced surgical technology, ORP remains an effective treatment option for prostate cancer when performed by experienced surgeons.

Theorising masculinity, ageing, and the lived body: the case of prostate cancer

This article conceptualises how masculinity and masculine ideals are played out in relation to prostate cancer treatment and its side-effects, offering a heuristic and theoretical perspective with which to make sense of the complex interrelationship between lived gendered bodies and social structures. With the support of three case studies of older men treated for prostate cancer, the article explores how the concept of hegemonic masculinity can be used to analyse the ill and ageing body. A phenomenologically informed approach to the body, which illustrates how masculinity is lived and experienced through certain body schemas, is used. The three case studies show variation in how masculinity is enacted and embodied, illustrating actions to (1) restore and maintain masculinity through phallic experience; (2) reconstruct masculinity by connecting bodily experience to notions of the ageing and a less potent body; and (3) to counter narrowly defined notions of masculinity by dissociating or decoupling masculinity from ideals of potency and performance. With the help of the case studies, the strategies identified, and the fluidity and dynamism of the concept of hegemonic masculinity, findings reveal how inequalities between men and women are produced and maintained, in and through bodily experience, and diverse body schemas.

Occupational exposures of firefighting and prostate cancer risk in the Norwegian Fire Departments Cohort.

Excess incidence of prostate cancer (PC) is frequently observed among firefighters; however, the association with specific occupational exposures of firefighting, as well as the influence of a medical surveillance bias, remains unclear. Our aim was to study PC risk within a firefighter cohort, applying indicators of exposures. We used indicators of various firefighting exposures to examine PC risk among men in the Norwegian Fire Departments Cohort (N=4251). Incident PC cases, including clinical characteristics, were obtained from the Cancer Registry of Norway (1960-2021). Cox regression was used to estimate hazard ratios (HR) by cumulative exposure in tertiles (reference: lowest) for all, aggressive, and indolent PC, with adjustment for age and birth cohort. The cumulative incidence of PC across birth cohorts and diagnostic periods was examined. No clear associations emerged for any of the exposure indicators, although we observed an HR of 1.31 [95% confidence interval (CI) 0.63-2.72] for aggressive PC in the highest tertile of fire exposure score and 1.31 (95% CI 0.60-2.89) for indolent PC in the highest tertile of inhalation score. Assessment of cumulative incidence demonstrated a greater number of diagnoses at younger ages after 1990, particularly for indolent and unclassifiable PC. We found little support for an association between firefighting exposures and PC risk. However, our study had few cases in analyses by clinical stage. Challenges in studies of firefighters' PC risk remain, including difficulties in exposure characterization and the unclear magnitude of a medical surveillance bias.

NSQIP surgical risk calculator: a useful adjunct for the urology multidisciplinary meeting.

Surgical risk calculators are not often routinely used in Urology Multidisciplinary Meetings (MDM), and little is known about their impact on clinical decision-making. The aim of this study is to assess the utility of the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) risk calculator for decision-making in the Urology MDM setting, with particular consideration given to decisions about surgical candidacy. We analysed all adult patients discussed in our Urology MDM with urological conditions whose management plan could potentially include major surgery. During a MDM, a consensus management decision was made prior to the NSQIP score being revealed to blinded team members. Any change in decision after revealing the score was documented, including rationale. Sixty-three out of 64 eligible cancer cases being discussed at MDM warranted NSQIP scores being revealed to the MDM post initial consensus. 95.2% (n = 60) did not have a change in the MDM management plan after reveal of NSQIP score. The NSQIP score led to a change in the MDM management decision in three cases: two renal cancer cases where management changed to biopsy with view to microwave ablation if positive, and one prostate cancer case, where management changed to recommend against radical prostatectomy. The NSQIP risk calculator was a useful tool and adjunct in the MDM setting. It served as a safety net where surgical risk was not initially properly estimated by team members, and reinforced decisions where there was concordance between NSQIP score and clinical judgement.

The Value of Digital Rectal Examination (DRE) in Prostate Cancer Diagnostics.

Background and objective Prostate cancer (PCA) is the most prevalent cancer among males.The National Institute for Health and Care Excellence (NICE) recommends referral to PCA diagnostic pathway based on two criteria: (1) abnormal digital rectal examination (DRE)and (2) elevated prostate-specific antigen (PSA).This study evaluates the diagnostic value of routine DRE in patients undergoing PCA assessment with pre-biopsy MRI. Methods We conducted a retrospective analysis of 436 patients on the PCA diagnostic pathway between September 2019 and June 2020, focusing on those with normal MRI [Prostate Imaging Reporting and Data System (PI-RADS) 1-2, n=147] and documented DRE results.Patients were categorised by their DRE status: normal vs. abnormal. The detection of prostate cancer and clinically significant prostate cancer (CSPC, i.e.,Gleason score ≥7) was then compared between the two groups. Results The overall PCA detection rate was 10.2%, while it was 4.67% for CSPC.PCA and CSPC detection were higher with abnormal DRE (19.35% and 6.45% respectively) compared to normal DRE (7.76% and 4.31%). Among 23 patients biopsied, 65% (n=15) had PCA, with CSPC found in 30% (n=7). Of note, 61% (n=14) of biopsied patients had normal DRE, with nine PCA cases, five being CSPC, whereas 39% (n=9) with abnormal DRE had six PCA cases, two being CSPC. Statistical analysis using McNemar's test showed no significant association between DRE and PCA diagnosis (p=0.146) or CSPC (p=0.774). Even thoughabnormal DRE was associated with higher PCA and CSPC detection rates, this finding was not statistically significant. Conclusions Based on our findings, PCA diagnostics can beeffectively performed without DRE. This finding is pertinent when performing remote PCA diagnostic consultations, and it reevaluatesDRE'svalue within the diagnostic pathway while emphasising a PSA- and MRI-based approach.
