Uleri A, Cornu JN, Gobbo A, Herrmann TRW, De Nunzio C, Hashim H, Baboudjian M. Association of 5α-Reductase Inhibitors with Depression and Suicide: A Mini Systematic Review and Meta-analysis. Eur Urol Focus 2024:S2405-4569(24)00062-2. [PMID: 38692949 DOI: 10.1016/j.euf.2024.04.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2024] [Revised: 03/29/2024] [Accepted: 04/24/2024] [Indexed: 05/03/2024]
Abstract
5α-Reductase inhibitors (5-ARIs) are widely prescribed for treatment of benign prostatic obstruction and androgenic alopecia. Several studies with controversial findings regarding 5-ARI exposure have been published over a number of years, and concerns were recently raised about the potential risks of depression and suicide associated with 5-ARIs. To investigate this association, we conducted a systematic review of the literature and a meta-analysis. Five studies involving 2213600 patients met our inclusion criteria. We found no statistically significant association between 5-ARI exposure and the risk of depression (adjusted hazard ratio [aHR] 1.30, 95% confidence interval [CI] 0.85-2.00; p = 0.23) or suicide (aHR 1.30, 95% CI 0.65-2.61; p = 0.45). Subgroup analyses for finasteride and dutasteride revealed similar results. When restricting the analysis to patients without a prior diagnosis of depression, we observed similar findings (aHR for suicide 1.00, 95% CI 0.68-1.46; p = 0.98). PATIENT SUMMARY: We reviewed study data for more than two million patients taking drugs called 5α-reductase inhibitors (5-ARIs), which are widely prescribed for urinary problems caused by benign prostate enlargement and for male-pattern hair loss. In a pooled analysis we found no evidence of an association between 5-ARI use and the risk of depression or suicide.

Abstract
INTRODUCTION Treatment of lower urinary tract symptoms (LUTS) related to benign prostatic hyperplasia (BPH) has shifted over the last decades, with medical therapy becoming the primary treatment modality while surgery is being reserved mostly to patients who are not responding to medical treatment or presenting with complications from BPH. Here, we aim to to discuss the optimal timing of surgical management of LUTS/BPH. MATERIALS AND METHODS A literature search was conducted on Pub-Med/MEDLINE database to identify reports published from January 1990 until January 2022 by combining the following MeSH terms: "Lower Urinary Tract Symptoms"; "Prostatic Hyperplasia"; "Prostatic Hyperplasia/therapy"; "Prostatic Hyperplasia/complications"; "Treatment Outcome"; "Time-to-Treatment". Evidence supporting or not early surgical treatment of BPH was examined and reported in a pros and cons form. RESULTS The "pro early surgery" highlighted the superior efficacy and cost-effectiveness of surgery over medical treatment for BPH, as well as the possibility of worse postoperative outcomes for delayed surgical treatment. The "con early surgery" considered that medical therapy is efficient in well-selected patients and can avoid the serious risks inherent to surgical treatment of BPH including important sexual side effects. CONCLUSIONS Clinical trials comparing the outcomes for prolonged medical therapy versus early surgical treatment could determine which approach is more beneficial in the long-term in context of the aging population. Until then, both approaches have their advantages and patients should be involved in the treatment decision.

Abstract
Post-finasteride syndrome and post-SSRI sexual dysfunction, are two poorly explored clinical conditions in which men treated for androgenetic alopecia with finasteride or for depression with SSRI antidepressants show persistent side effects despite drug suspension (e.g., sexual dysfunction, psychological complaints, sleep disorders). Because of some similarities in the symptoms, common pathological mechanisms are proposed here. Indeed, as discussed, clinical studies and preclinical data obtained so far suggest an important role for brain modulators (i.e., neuroactive steroids), neurotransmitters (i.e., serotonin, and cathecolamines), and gut microbiota in the context of the gut-brain axis. In particular, the observed interconnections of these signals in these two clinical conditions may suggest similar etiopathogenetic mechanisms, such as the involvement of the enzyme converting norepinephrine into epinephrine (i.e., phenylethanolamine N-methyltransferase). However, despite the current efforts, more work is still needed to advance the understanding of these clinical conditions in terms of diagnostic markers and therapeutic strategies.

Abstract
Finasteride may cause low libido and erectile dysfunction and the product label of finasteride also includes post-marketing reactions of sexual dysfunction that continued after discontinuation of treatment, as well as male infertility and depression. The aim of this study was to evaluate the beliefs and counseling practices among dermatologists regarding adverse effects of finasteride. Anonymous paper surveys were personally distributed to 122 attendees at two annual major dermatology meetings. The participation rate was 82% with 47% women and 77% residents of the United States. 51% of respondents believed that finasteride could cause sexual side effects and 18% believed that it could cause persistent sexual side effects. Fewer than a quarter believed that finasteride could cause depression or lower sperm counts. When initiating finasteride, 69% of respondents counseled at least half of their patients about potential sexual side effects with 52% for persistent sexual side effects and 30% for depression. This study identifies the need for greater awareness of the potential adverse effects of finasteride and identifies opportunities for improvement in counseling practices that reflect finasteride's product labeling.

Sci Rep 2023; 13:5308. [PMID: 37002313 PMCID: PMC10066399 DOI: 10.1038/s41598-023-32356-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2022] [Accepted: 03/26/2023] [Indexed: 04/03/2023] Open
Abstract
Finasteride, a 5α-reductase inhibitor used in benign prostatic hyperplasia and androgenetic alopecia, has been associated with an increased suicidal risk, whereas it is unclear whether such risk is similar to that for another 5α-reductase inhibitor, dutasteride. We aimed to assess the risk of suicidal behaviours with finasteride relative to dutasteride. A nationwide cohort study was conducted using the French National Health Data System (SNDS). Men aged 50 years or older initiating finasteride 5 mg or dutasteride 0.5 mg in France between 01-01-2012 and 30-06-2016 were included and followed until outcome (suicide death identified from death certificate or self-harm hospitalisation), treatment discontinuation or switch, death, or 31-12-2016. Self-harm by violent means or resulting in admission to an intensive care unit were also examined. Cox proportional hazards models controlled for age and psychiatric and non-psychiatric conditions by inverse probability of treatment weighting (IPTW). Analyses were stratified according to psychiatric history. The study compared 69,786 finasteride new users to 217,577 dutasteride new users (median age: 72.0 years [Q1-Q3 = 64.5-80.2] vs. 71.1 [Q1-Q3 = 65.0-79.2]). During follow-up, 18 suicide deaths (0.57/1000 person-years) and 34 self-harm hospitalisations (1.08/1000) occurred among finasteride users versus 47 deaths (0.43/1000) and 87 hospitalisations (0.79/1000) among dutasteride users. Overall, finasteride was not associated with an increased risk of any suicidal outcome (IPTW-adjusted Hazard Ratio = 1.21 [95% Confidence Interval .87-1.67]), suicide death or self-harm hospitalisation. However, among individuals with a history of mood disorders, finasteride was associated with an increased risk of any suicidal outcome (25 versus 46 events; HR = 1.64 [95% CI 1.00-2.68]), suicide death (8 versus 10 events; HR = 2.71 [95% CI 1.07-6.91]), self-harm by violent means (6 versus 6 events; HR = 3.11 [95% CI 1.01-9.61]), and self-harm with admission to an intensive care unit (7 versus 5 events; HR = 3.97 [95% CI 1.26-12.5]). None of these risks was significantly increased among individuals without a psychiatric history. These findings do not support an increased risk of suicide with finasteride used in the treatment of benign prostatic hyperplasia. However, an increased risk cannot be excluded among men with a history of mood disorder, but this result based on a limited number of events should be interpreted with caution.

Abstract
Importance In recent decades, there has been increased interest in the possible adverse neurological effects of 5α-reductase inhibitors (5-ARIs), which have been used mainly for benign prostatic hyperplasia and androgenic alopecia. Numerous studies and reports have indicated associations of 5-ARIs with depression and suicide. However, most of these studies had methodological shortcomings, and very little is known about the potential association of 5-ARIs with dementia. Objective To investigate the association of 5-ARI use with all-cause dementia, Alzheimer disease, vascular dementia, depression, and suicide. Design, Setting, and Participants This Swedish register-based cohort study included 2 236 876 men aged 50 to 90 years between July 1, 2005, and December 31, 2018. Statistical analyses were performed from September 15, 2021, to May 25, 2022. Main Outcomes and Measures A diagnosis of all-cause dementia, Alzheimer disease, vascular dementia, depression, or completed suicide. Exposures A recorded prescription in the Swedish national prescription register of finasteride or dutasteride and duration of use. Results Of 2 236 876 men (median age at the start of follow-up, 55 years [IQR, 50-65 years] and at treatment initiation, 73 years [IQR, 66-80 years]), 70 645 (3.2%) started finasteride treatment, and 8774 (0.4%) started dutasteride treatment. Men taking finasteride or dutasteride were at increased risk of all-cause dementia (finasteride: hazard ratio [HR], 1.22 [95% CI, 1.17-1.28]; dutasteride: HR, 1.10 [95% CI, 1.01-1.20]), Alzheimer disease (finasteride: HR, 1.20 [95% CI, 1.10-1.31]; dutasteride: HR, 1.28 [95% CI, 1.09-1.50]), vascular dementia (finasteride: HR, 1.44 [95% CI, 1.30-1.58]; dutasteride: HR, 1.31 [95% CI, 1.08-1.59]), and depression (finasteride: HR, 1.61 [95% CI, 1.48-1.75]; dutasteride: HR, 1.68 [95% CI, 1.43-1.96]). However, the magnitude of the association decreased over time, and the findings became statistically nonsignificant with continuous exposures over 4 years, except for depression, which showed a constant risk over time, with no differences between finasteride and dutasteride. In contrast, 5-ARIs were not associated with suicide (finasteride: HR, 1.22 [95% CI, 0.99-1.49]; dutasteride: HR, 0.98 [95% CI, 0.62-1.54]). Conclusions and Relevance This cohort study found that, while men receiving 5-ARI treatment showed a higher risk for dementia in the initial periods after starting treatment, the decreasing magnitude of the association over time suggested that the risk may be, entirely or in part, due to increased dementia detection among patients with benign prostate enlargement. Both finasteride and dutasteride were similarly associated with depression with a constant risk over time, while neither drug was associated with suicide. Prescribing clinicians and potential users should be aware of the possible risks for depression associated with 5-ARI use.

Abstract
BACKGROUND How 5-alpha reductase inhibitor (5-ARI) use influences prostate cancer mortality is unclear. The objective of this study was to determine whether men taking 5-ARIs with regular health care access have increased prostate cancer mortality. METHODS We undertook two analyses in the Health Professionals Follow-up Study examining 5-ARI use, determined by biennial questionnaires, and prostate cancer. A cohort analysis followed 38,037 cancer-free men for prostate cancer incidence from 1996 through January 2017 and mortality through January 2019. A case-only analysis followed 4,383 men with localized/locally advanced prostate cancer for mortality over a similar period. HRs and 95% confidence intervals (CI) were calculated for prostate cancer incidence and mortality. RESULTS Men using 5-ARIs underwent more PSA testing, prostate exams and biopsies. Over 20 years of follow-up, 509 men developed lethal disease (metastases or prostate cancer death). Among men initially free from prostate cancer, 5-ARI use was not associated with developing lethal disease [HR, 1.02; 95% confidence interval (CI), 0.71-1.46], but was associated with reduced rates of overall and localized disease (HR, 0.71; 0.60-0.83). Among men diagnosed with prostate cancer, there was no association between 5-ARI use and cancer-specific (HR, 0.78; 95% CI, 0.48-1.27) or overall survival (HR, 0.88; 95% CI, 0.72-1.07). CONCLUSIONS Men using 5-ARIs were less likely to be diagnosed with low-risk prostate cancer, without increasing long-term risk of lethal prostate cancer or cancer-specific death after diagnosis. IMPACT Our results provide evidence that 5-ARI use is safe with respect to prostate cancer mortality in the context of regular health care access. See related commentary by Hamilton, p. 1259.

Abstract
Background Prostate cancer (PC) aetiology is unclear. PC risk was examined in relation to several factors in a large population-based prospective study. Methods Male participants were from Sax Institute’s 45 and Up Study (Australia) recruited between 2006 and 2009. Questionnaire and linked administrative health data from the Centre for Health Record Linkage and Services Australia were used to identify incident PC, healthcare utilisations, Prostate Specific Antigen (PSA) testing reimbursements and dispensing of metformin and benign prostatic hyperplasia (BPH) prescriptions. Multivariable Cox and Joint Cox regression analyses were used to examine associations by cancer spread, adjusting for various confounders. Results Of 107,706 eligible men, 4257 developed incident PC up to end 2013. Risk of PC diagnosis increased with: PC family history (versus no family history of cancer; HRadjusted = 1.36; 95% CI:1.21–1.52); father and brother(s) diagnosed with PC (versus cancer-free family history; HRadjusted = 2.20; 95% CI:1.61–2.99); severe lower-urinary-tract symptoms (versus mild; HRadjusted = 1.77; 95% CI:1.53–2.04) and vasectomy (versus none; HRadjusted = 1.08; 95% CI:1.00–1.16). PC risk decreased with dispensed prescriptions (versus none) for BPH (HRadjusted = 0.76; 95% CI:0.69–0.85) and metformin (HRadjusted = 0.57; 95% CI:0.48–0.68). Advanced PC risk increased with vasectomy (HRadjusted = 1.28; 95% CI:1.06–1.55) and being obese (versus normal weight; HRadjusted = 1.31; 95% CI:1.01–1.69). Conclusion Vasectomy and obesity are associated with an increased risk of advanced PC. The reduced risk of localised and advanced PC associated with BPH, and diabetes prescriptions warrants investigation.

[PMID: 34479019 DOI: 10.1016/j.biopha.2021.112100] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2021] [Revised: 08/20/2021] [Accepted: 08/23/2021] [Indexed: 11/16/2022] Open
Abstract
Recent literature connects 5-alpha reductase inhibitors (5-ARIs) with neuropsychiatric adverse effects. Several clinical studies have indicated that former 5-ARIs users had a higher incidence of depressive symptoms and neuropsychiatric side effects than non-users. However, the underlying mechanisms involved in the depression in former 5-ARIs patients, a condition known as "post finasteride syndrome (PFS)", are not thoroughly understood. This review aims to summarize and discuss the association between 5-ARIs and depression as well as possible mechanisms. We used PubMed search terms including "depression", "depressive symptoms", "MDD", "anxiety", or "suicidal idea", and "5-alpha reductase inhibitors", "finasteride", "dutasteride", "5-ARIs". All relevant articles from in vivo and clinical studies from 2002 to 2021 were carefully reviewed. Any contradictory findings were included and debated. The potential mechanisms that link 5-ARIs and depression include alteration in neuroactive steroids, dopaminergic dysfunction, reduced hippocampal neurogenesis, increased neuroinflammation, alteration of the HPA axis, and epigenetic modifications. From this review, we hope to provide information for future studies based on animal experiments, and potential therapeutic strategies for depressive patients with PFS.

Abstract
BACKGROUND Finasteride is one of several inhibitors of the 5α-reductase that converts testosterone to dihydrotestosterone used to treat hair loss and benign prostatic enlargement. Emerging clinical observations indicate that such treatment may be associated with depression, anxiety, and possibly increased suicidal risks, in addition to sexual dysfunction, even after its discontinuation. METHODS We carried out a systematic review of reports pertaining to association of finasteride treatment with clinical depression or other adverse psychiatric effects. We analyzed reported risks of depression by pooling of rates and by meta-analysis of comparisons of subjects treated with finasteride or not. FINDINGS Crude pooled rates of depressive symptoms with versus without finasteride were 3.33% (confidence interval, 3.22%-3.44%) versus 2.54% (2.44%-2.64%); random-effects meta-analysis yielded an odds ratio of 2.14 (1.40-3.27) (both P < 0.0001). In addition, risk of suicidal ideation or behavior was greater with versus without finasteride (21.2% [21.0%-21.5%] vs 14.0% [13.8%-14.2%], P < 0.0001), and risk of sustained sexual dysfunction was high (60.1% [37.3%-82.9%]). CONCLUSIONS The findings support a growing impression that finasteride is associated with adverse psychiatric effects that can persist in association with sexual dysfunction after discontinuing finasteride treatment.

Abstract
Background and objectives: Treatment of lower urinary tract symptoms (LUTS) related to benign prostatic hyperplasia (BPH) has shifted over the last decades, with medical therapy becoming the primary treatment modality while surgery is being reserved mostly to patients who are not responding to medical treatment or presenting with complications from BPH. Here, we aim to explore the evidence supporting or not early surgical treatment of BPH as opposed to prolonged medical therapy course. Materials and Methods: The debate was presented with a “pro and con” structure. The “pro” side supported the early surgical management of BPH. The “con” side successively refuted the “pro” side arguments. Results: The “pro” side highlighted the superior efficacy and cost-effectiveness of surgery over medical treatment for BPH, as well as the possibility of worse postoperative outcomes for delayed surgical treatment. The “con” side considered that medical therapy is efficient in well selected patients and can avoid the serious risks inherent to surgical treatment of BPH including important sexual side effects. Conclusions: Randomized clinical trials comparing the outcomes for prolonged medical therapy versus early surgical treatment could determine which approach is more beneficial in the long-term in context of the aging population. Until then, both approaches have their advantages and patients should be involve in the treatment decision.

Abstract
Introduction The recommended treatment for bothersome lower urinary tract symptoms (LUTS) secondary to benign prostatic obstruction (BPO) after the failure of behavioral therapy and fluid modification includes pharmacological, minimally invasive interventional, and surgical approaches. Each option has different risk and benefit profiles, and the urologist must be aware of the unique characteristics of each option in order to be able to accurately counsel the patients based on their individual values and preferences. We provide a comparative review of the commonest pharmacological and most widely performed interventional/surgical treatments for BPO, discussing the evidence for the treatment characteristics that are most useful for the practicing urologist. Methods A search of the PubMed database was performed for articles reporting on the following treatments for LUTS due to BPO: α‐blockers, 5α‐reductase inhibitors, phosphpdiesterase‐5 inhibitors, prostatic urethral lift (Urolift), convective radiofrequency water vapor thermal therapy (Rezum), Temporary implantable Nitinol Device (iTIND), prostate artery embolization (PAE), transurethral resection of the prostate (TURP), photoselective vaporization of the prostate (PVP), Aquablation, and anatomical endoscopic enucleation of the prostate (AEEP). We performed a narrative review focussing on the following outcomes: efficacy, safety, durability, duration of catheterization, length of stay, re‐treatment rate, efficacy in special situations (enlarged median lobe, prostate size, urinary retention, and anticoagulant use), and sexual adverse events. Results AEEP offers the greatest long‐term improvement in maximum flow rate, IPSS, and prostate volume reduction, with lowest re‐treatment rate, followed by PVP, TURP, and Aquablation. Urolift, Rezum, and PAE have similar efficacy for prostate volume up to 80cc, and all are more effective than the pharmacological treatment. Urolift offers the lowest rate of sexual dysfunction, followed by Rezum, and both can be performed as a day case under local anesthesia. Conclusion Several treatment options exist to treat voiding LUTS due to BPO. Newer minimally invasive treatments reduce the hospital stay and postoperative complications, whereas AEEP provides the greatest long‐term symptom improvement at the expense of higher morbidity and sexual dysfunction. Men should be counseled regarding all suitable treatment options as some may favor reduced efficacy in association with reduced side effects.

Abstract
Increasingly sophisticated therapies for chemical castration dominate first-line treatments for locally advanced prostate cancer. However, androgen deprivation therapy (ADT) offers little prospect of a cure, as resistant tumors emerge rather rapidly, normally within 30 months. Cells have multiple mechanisms of resistance to even the most sophisticated drug regimes, and both tumor cell heterogeneity in prostate cancer and the multiple salvage pathways result in castration-resistant disease related genetically to the original hormone-naive cancer. The timing and mechanisms of cell death after ADT for prostate cancer are not well understood, and off-target effects after long-term ADT due to functional extra-prostatic expression of the androgen receptor protein are now increasingly being recorded. Our knowledge of how these widely used treatments fail at a biological level in patients is deficient. In this review, I will discuss whether there are pre-existing drug-resistant cells in a tumor mass, or whether resistance is induced/selected by the ADT. Equally, what is the cell of origin of this resistance, and does it differ from the treatment-naïve tumor cells by differentiation or dedifferentiation? Conflicting evidence also emerges from studies in the range of biological systems and species employed to answer this key question. It is only by improving our understanding of this aspect of treatment and not simply devising another new means of androgen inhibition that we can improve patient outcomes.

Abstract
Session IV of the Second International Colloquium on Cardio-Oncology held in Kraków, focused on the cardiovascular risks of using hormone replacement therapy in breast cancer and androgen deprivation therapy in prostate cancer and continued the theme from Session 3 with a discussion of risk reduction strategies. The discussion then moved to an overview of modern radiation therapy and evolving mechanisms of cardioprotection. The risks and late cardiotoxic effects that must be considered in patients treated prior to the "modern era" were enumerated stressing the importance of long term follow-up of this population.

Abstract
Background Investigators have used administrative claims to better understand cancer outcomes when a research question cannot feasibly be examined within a study. The Prostate Cancer Prevention Trial (PCPT) showed that seven years of finasteride reduced prostate cancer (PC) risk by 25% in men age 55 years or older. However, it was unclear whether the observed reduction in PC for finasteride participants would be maintained after finasteride discontinuation. Methods We examined PC diagnoses identified by PCPT study records and Medicare claims (finasteride = 9423, placebo = 9457). A Medicare-defined PC diagnosis algorithm was defined using diagnosis and procedure codes. Multivariable Cox regression was used to examine time to PC within prespecified follow-up windows (<6.5, 6.5-7.5, and >7.5 years) using time-dependent covariates interacting with intervention assignment to account for the PCPT protocol-specified end-of-study biopsy at seven years. All statistical tests were two-sided. Results Median follow-up using the linked database was 16 years. Overall, finasteride arm participants had a 21.1% decrease in the hazard ratio of PC (hazard ratio [HR] = 0.79, 95% confidence interval [CI] = 0.74 to 0.84, P < .001). The beneficial effect of finasteride in reducing the hazard ratio of PC was most pronounced in the first 7.5 years (HR = 0.71, 95% CI = 0.66 to 0.77, P < .001), consistent with the original study findings; after 7.5 years, there was no increased risk of PC for finasteride arm participants (HR = 1.10, 95% CI = 0.96 to 1.26, P = .18). Conclusions Finasteride provides a substantial reduction in PC through 16 years of follow-up. There was no strong evidence that the benefit of finasteride diminished after the end-of-study follow-up. Utilizing Medicare claims to augment PCPT follow-up illustrates how the novel use of secondary data sources can enhance the ability to detect long-term outcomes from prospective studies.

Abstract
Introduction: Muscarinic receptor antagonists, 5α-reductase inhibitors and α1-adrenoceptor antagonists are frequently used drug classes for the treatment of lower urinary tract symptoms including those of overactive bladder syndrome and benign prostatic enlargement/benign prostatic obstruction. Areas covered: The authors review the evidence for adverse effects of these drug classes on cognitive function, mood and other functions of the central nervous system and discuss such effects against the evidence for mechanistic plausibility. Expert opinion: Muscarinic antagonists carry a risk for impaired cognition and other brain functions that differs quantitatively between compounds, being highest with oral formulations of oxybutynin. 5□-Reductase inhibitors can cause depressive symptoms even at low doses and starting several months after discontinuation of treatment. The evidence for α1-adrenoceptor antagonists and specifically tamsulosin to cause dementia is controversial and lacks mechanistic plausibility. We recommend that physicians treating patients with lower urinary tract symptoms carefully monitor mental status prior to prescribing and periodically thereafter.

Abstract
PURPOSE Although five-alpha reductase inhibitor (5-ARI) is one of standard treatment for benign prostatic hyperplasia (BPH) or alopecia, potential complications after 5-ARI have been issues recently. This study aimed to investigate the risk of depression after taking 5-ARI and to quantify the risk using meta-analysis. MATERIALS AND METHODS A total of 209,940 patients including 207,798 in 5-ARI treatment groups and 110,118 in control groups from five studies were included for final analysis. Inclusion criteria for finial analysis incudes clinical outcomes regarding depression risk in BPH or alopecia patients. Overall hazard ratio (HR) and odds ratio (OR) for depression were analyzed. Moderator analysis and sensitivity analysis were performed to determine whether HR or OR could be affected by any variables, including number of patients, age, study type, and control type. RESULTS The pooled overall HRs for the 5-ARI medication was 1.23 (95% confidence interval [CI], 0.99-1.54) in a random effects model. The pooled overall ORs for the 5-ARI medication was 1.19 (95% CI, 0.95-1.49) in random effects model. The sub-group analysis showed that non-cohort studies had higher values of HR and OR than cohort studies. Moderator analysis using meta-regression showed that there were no variables that affect the significant difference in HR and OR outcomes. However, in sensitivity analysis, HR was significantly increased by age (p=0.040). CONCLUSIONS Overall risk of depression after 5-ARI was significantly not high, however its clinical importance needs validation by further studies. These quantitative results could provide useful information for both clinicians and patients.

Abstract
Benign prostatic hyperplasia (BPH) is a common disease in men. Although transurethral resection of the prostate (TURP) is the gold standard therapy for treatment of BPH and associated lower urinary tract symptoms (LUTS), many patients choose to avoid surgery and instead choose medical therapy. Until recently, medical therapy for BPH has been thought to be both safe and effective. However, new studies have shown that some of these medications can have significant neurocognitive, psychiatric, and sexual side effects, including dementia and depression. As most patients taking these medications will continue them for the long term, it is vital for physicians to explain these potential risks to the patient prior to prescribing them for a quality-of-life condition.

Abstract
SIGNIFICANCE Cancer cells that are resistant to radiation and chemotherapy are a major problem limiting the success of cancer therapy. Aggressive cancer cells depend on elevated intracellular levels of reactive oxygen species (ROS) to proliferate, self-renew, and metastasize. As a result, these aggressive cancers maintain high basal levels of ROS compared with normal cells. The prominence of the redox state in cancer cells led us to consider whether increasing the redox state to the condition of oxidative stress could be used as a successful adjuvant therapy for aggressive cancers. Recent Advances: Past attempts using antioxidant compounds to inhibit ROS levels in cancers as redox-based therapy have met with very limited success. However, recent clinical trials using pro-oxidant compounds reveal noteworthy results, which could have a significant impact on the development of strategies for redox-based therapies. CRITICAL ISSUES The major objective of this review is to discuss the role of the redox state in aggressive cancers and how to utilize the shift in redox state to improve cancer therapy. We also discuss the paradox of redox state parameters; that is, hydrogen peroxide (H2O2) as the driver molecule for cancer progression as well as a target for cancer treatment. FUTURE DIRECTIONS Based on the biological significance of the redox state, we postulate that this system could potentially be used to create a new avenue for targeted therapy, including the potential to incorporate personalized redox therapy for cancer treatment.

Abstract
BACKGROUND The cancer research groups of the National Cancer Institute's National Clinical Trials Network have a history of successful conduct of large randomized phase III trials of chemoprevention for cancer. An important question for funding agencies is whether the conduct of large chemoprevention trials provides strong scientific return on investment. METHODS We evaluated the scientific impact of four large chemoprevention trials - two for breast cancer and two for prostate cancer - using citation analysis, a bibliometric technique. The results were compared to the scientific impact of a series of treatment trials conducted over the same 20-year time period (1991-2010, inclusive). Average annual citation counts were compared using t-tests. Scientific impact was also assessed relative to trial costs. RESULTS Twenty-seven treatment trials with 17,208 patients and four chemoprevention trials with 87,550 patients were examined. The mean annual citation rate for primary articles was higher for chemoprevention trials compared to treatment trials (188.1 vs. 40.4, p = .001). For both primary and secondary article publications, mean annual citations for articles associated with chemoprevention trials were also higher (483.9 vs. 69.0, p = .0003). Large chemoprevention trials were estimated to provide 50% more total citations from primary and secondary articles on a cost-adjusted basis. CONCLUSION Based on these criteria, the scientific impact of large phase III cancer chemoprevention trials was very high in absolute terms, and as good as or better than that of treatment trials after accounting for expenditure. For appropriate scientific questions, large chemoprevention trials provide a good scientific return on investment for federal funding agencies.

Leão RRN, Price AJ, James Hamilton R. Germline BRCA mutation in male carriers-ripe for precision oncology? Prostate Cancer Prostatic Dis 2017; 21:48-56. [PMID: 29242595 DOI: 10.1038/s41391-017-0018-5] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2017] [Accepted: 08/20/2017] [Indexed: 02/06/2023]
Abstract
BACKGROUND Prostate cancer (PC) is one of the known heritable cancers with individual variations attributed to genetic factors. BRCA1 and BRCA2 are tumour suppressor genes with crucial roles in repairing DNA and thereby maintaining genomic integrity. Germline BRCA mutations predispose to multiple familial tumour types including PC. METHODS We performed a Pubmed database search along with review of reference lists from prominent articles to capture papers exploring the association between BRCA mtuations and prostate cancer risk and prognosis. Articles were retrieved until May 2017 and filtered for relevance, and publication type. RESULTS We explored familial PC genetics; discussed the discovery and magnitude of the association between BRCA mutations and PC risk and outcome; examined implications of factoring BRCA mutations into PC screening; and discussed the rationale for chemoprevention in this high-risk population. We confirmed that BRCA1/2 mutations confer an up to 4.5-fold and 8.3-fold increased risk of PC, respectively. BRCA2 mutations are associated with an increased risk of high-grade disease, progression to metastatic castration-resistant disease, and 5-year cancer-specific survival rates of 50 to 60%. CONCLUSION Despite the growing body of research on DNA repair genes, deeper analysis is needed to understand the aetiological role of germline BRCA mutations in the natural history of PC. There is a need for awareness to screen for this marker of PC risk. There is similarly an opportunity for structured PC screening programs for BRCA mutation carriers. Finally, further research is required to identify potential chemopreventive strategies for this high-risk subgroup.

Pre-radiotherapy PSA progression is a negative prognostic factor in prostate cancer patients using 5‑alpha-reductase inhibitors. Strahlenther Onkol 2017; 194:17-22. [PMID: 28695317 DOI: 10.1007/s00066-017-1176-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2017] [Accepted: 06/22/2017] [Indexed: 10/19/2022]
Abstract
OBJECTIVE To investigate the impact of 5‑alpha-reductase inhibitor (5-ARI) use on radiotherapy outcomes for localized prostate cancer. PATIENTS AND METHODS We included 203 patients on a 5-ARI from our institutional database comprising over 2500 patients who had been treated with either external beam radiotherapy (EBRT) or brachytherapy for localized prostate cancer. Patients received a 5-ARI for urinary symptoms or active surveillance. Cancer progressions at the time of definitive treatment were analyzed according to the following criteria: (a) progression of Gleason score or increase in cancer volume on biopsy, (b) first biopsy positive for cancer after being treated for urinary symptoms with a 5-ARI, and (c) prostate-specific antigen (PSA) progression with or without a previous cancer diagnosis. Biochemical failure (BF) was defined by the Phoenix definition. Log-rank test was used for survival analysis. RESULTS At a median follow-up of 38.2 months (standard deviation 22.2 months), 10 (4.9%) patients experienced BF. Concerning prostate cancer progression criteria, 52% of men demonstrated none, 37% showed only one criterion, and 11% showed two. Using univariate analysis, PSA progression (p = 0.004) and appearance of a positive biopsy (p < 0.001) were significant predictive factors for BF, while Gleason progression (p = 0.3) was not. In multivariate analysis adjusted for cancer aggressiveness, rising PSA (hazard ratio, HR, 5.7; 95% confidence interval, CI, 1.1-28.8; p = 0.04) and the number of cancer progression factors (HR 2.9, 95% CI 1.2-7.0, p = 0.02) remained adverse risk factors. CONCLUSION PSA progression experienced during 5‑ARI treatment before radiotherapy is predictive of worse biochemical outcome. Such details should be considered when counseling men prior to radiation therapy.

Abstract
IMPORTANCE There have been concerns raised by patients and regulatory agencies regarding serious psychiatric adverse effects associated with 5α-reductase inhibitors. OBJECTIVE To determine if there is an increased risk of suicide, self-harm, or depression among older men starting a 5α-reductase inhibitor for prostatic enlargement. DESIGN, SETTING, AND PARTICIPANTS A population-based, retrospective, matched cohort study using linked administrative data for 93 197 men ages 66 years or older (median [IQR] age, 75 [70-80] years) in Ontario, Canada, who initiated a new prescription for a 5α-reductase inhibitor during the study period (2003 through 2013). Participants were matched (using a propensity score that included 44 of our 96 covariates that included medical comorbidities, medication usage, and health care system utilization) to an equal number of men not prescribed a 5α-reductase inhibitor. EXPOSURES Duration of finasteride or dutasteride usage. MAIN OUTCOMES AND MEASURES Suicide. Secondary outcomes were self-harm and depression. RESULTS Men who used 5α-reductase inhibitors were not at a significantly increased risk of suicide (HR, 0.88; 95% CI, 0.53-1.45). Risk of self-harm was significantly increased during the initial 18 months after 5α-reductase inhibitor initiation (HR, 1.88; 95% CI, 1.34-2.64), but not thereafter. Incident depression risk was elevated during the initial 18 months after 5α-reductase inhibitor initiation (HR, 1.94; 95% CI, 1.73-2.16), and continued to be elevated, but to a lesser degree, for the remainder of the follow-up period (HR, 1.22; 95% CI, 1.08-1.37). The absolute increases in the event rates for these 2 outcomes were 17 per 100 000 patient-years and 237 per 100 000 patient-years, respectively. The type of 5α-reductase inhibitor (finasteride or dutasteride) did not significantly modify the observed associations with suicide, self-harm, and depression. CONCLUSIONS AND RELEVANCE In a large cohort of men ages 66 years or older, we did not demonstrate an increased risk of suicide associated with 5α-reductase inhibitor use. However, the risk of self-harm and depression were increased compared with unexposed men. This is in keeping with postmarketing experience and patient concerns, and discontinuation of the medication in these circ umstances may be appropriate.
