Diagnosis, Management, and Follow-Up of the Incidentally Discovered Adrenal Mass: CUA Guideline Endorsed by the AUA.

PURPOSE: Incidental adrenal masses are common and require a multidisciplinary approach to evaluation and management that includes family physicians, urologists, endocrinologists, and radiologists. The purpose of this guideline is to provide an updated approach to the diagnosis, management, and follow-up of adrenal incidentalomas, with a special focus on the areas of discrepancy/controversy existing among the published guidelines from other associations. MATERIALS AND METHODS: This guideline was developed by the Canadian Urological Association (CUA) through a working group comprised of urologists, endocrinologists, and radiologists and subsequently endorsed by the American Urological Association (AUA). A systematic review utilizing the GRADE approach served as the basis for evidence-based recommendations with consensus statements provided in the absence of evidence. For each guideline statement, the strength of recommendation was reported as weak or strong, and the quality of evidence was evaluated as low, medium, or high. RESULTS: The CUA working group provided evidence- and consensus-based recommendations based on an updated systematic review and subject matter expertise. Important updates on evidence-based radiological evaluation and hormonal testing are included in the recommendations. This guideline clarifies which patients may benefit from surgery and highlights where short term surveillance is appropriate. CONCLUSION: Incidentally detected adrenal masses require a comprehensive assessment of hormonal function and oncologic risk. This guideline provides a contemporary approach to the appropriate clinical, radiographic, and endocrine assessments required for the evaluation, management, and follow-up of patients with such lesions.

Temporal trends in management and outcomes of testicular cancer: A population-based study.

BACKGROUND: Treatment guidelines for early-stage testicular cancer have increasingly recommended de-escalation of therapy with surveillance strategies. This study was designed to describe temporal trends in routine clinical practice and to determine whether de-escalation of therapy is associated with inferior survival in the general population. METHODS: The Ontario Cancer Registry was linked to electronic records of treatment to identify all patients diagnosed with testicular cancer treated with orchiectomy in Ontario during 2000-2010. Treatment after orchiectomy was classified as radiotherapy (RT), retroperitoneal lymph node dissection (RPLND), chemotherapy, or none. Surveillance was defined as no identified treatment within 90 days of orchiectomy. Overall survival (OS) and cancer-specific survival (CSS) were measured from the date of orchiectomy. RESULTS: The study population included 1564 and 1086 cases of seminomas and nonseminoma germ cell tumors (NSGCTs), respectively. Among patients with seminomas, there was a significant increase in the proportion of patients with no treatment within 90 days of orchiectomy (from 56% to 84%; P < .001); the use of RT decreased over time (from 38% to 8%; P < .001); and the use of chemotherapy remained stable (from 6% to 9%; P = .289). Practice patterns 90 days after orchiectomy remained stable over time among patients with NSGCTs: from 51% to 57% for no treatment (P = .435), from 43% to 43% for chemotherapy (P = .336), and from 9% to 3% for RPLND (P = .476). The OS rates for the entire cohort at 5 and 10 years were 97% and 96%, respectively; the CSS rates were 98% and 98%, respectively. There was no significant change in OS or CSS for patients with seminomas or NSGCTs during the study period. CONCLUSIONS: There has been substantial de-escalation in the treatment of testicular cancer in routine practice since 2000. Long-term survival in routine practice is excellent and has not decreased with the uptake of surveillance strategies. Cancer 2018;124:2724-2732. © 2018 American Cancer Society.

Patient-reported outcome measures in urology.

PURPOSE OF REVIEW: Many urologic treatments have similar clinical outcomes, necessitating alternative methods to discriminate between options. Patient-reported outcome measures (PROMs) have become the new standard for evaluating the patient experience, and their use has drastically increased over the past decade. The purpose of this review is to discuss the status of PROMs in urology, highlight commonly used tools and address their future direction. RECENT FINDINGS: An increasing number of urology-specific PROMs tools have been developed and validated. An increased focus on patient-centered care has provided an impetus for their rise in use. Implementation of PROMs has transitioned from being primarily descriptive in nature to producing actionable findings. Many PROMs are now implemented in daily clinical practice. The future of PROMs will involve new instrument development, integration into clinical practice and the use of PROMs as performance measures. SUMMARY: PROMs are effective tools for characterizing symptom burden and health-related quality of life. With increasing clinical implementation, PROMs are playing an increasing role in patients' clinical decision-making.

Root Causes and Modifiability of 30-Day Hospital Readmissions after Radical Cystectomy for Bladder Cancer.

PURPOSE: Radical cystectomy is associated with high complication and rehospitalization rates. An understanding of the root causes of hospital readmissions and the modifiability of factors contributing to readmissions may decrease the morbidity associated with radical cystectomy. We characterize the indications for rehospitalization following radical cystectomy, and determine whether these indications represent immutable patient disease and procedure factors or whether they are modifiable. MATERIALS AND METHODS: From MarketScan® databases we identified patients younger than 65 years with a diagnosis of bladder cancer who underwent radical cystectomy between 2008 and 2011 and were readmitted to the hospital within 30 days of radical cystectomy. All associated ICD-9 codes in the index admission, subsequent outpatient claims and readmission claims were independently reviewed by 3 surgeons to determine a root cause of rehospitalization. Causes were broadly categorized as medical, surgical or infectious, and reviewers determined whether the readmission was modifiable. Multivariate logistical regression models were used to identify factors associated with rehospitalization. RESULTS: A total of 1,163 patients were included in the study and 242 (21%) were readmitted to the hospital within 30 days. Of these readmissions 26% were considered modifiable (kappa=0.71). Of the nonmodifiable readmissions an infectious cause accounted for 52% and a medical cause accounted for 48%, whereas of the modifiable readmissions 62% were due to surgical causes, 30% to medical and 8% to infectious causes. On multivariate analysis only discharge to a skilled nursing facility was associated with modifiable (OR 6.12, 95% CI 2.32-16.14) or nonmodifiable (OR 3.27, 95% CI 1.63-6.53) hospital readmissions. CONCLUSIONS: The majority of rehospitalizations after radical cystectomy are attributable its inherent morbidity. However, optimization of aspects of peri-cystectomy care could minimize the morbidity of radical cystectomy.

Identification of underserved areas for urologic cancer care.

BACKGROUND: The delivery of urologic oncology care is susceptible to regional variation. In the current study, the authors sought to define patterns of care for patients undergoing genitourinary cancer surgery to identify underserved areas for urologic cancer care in Washington State. METHODS: The authors accessed the Washington State Comprehensive Hospital Abstract Reporting System from 2003 through 2007. They identified patients undergoing radical prostatectomy, radical cystectomy (RC), partial nephrectomy (PN), radical nephrectomy, and transurethral resection of the prostate (TURP). TURP was included for comparison as a reference procedure indicative of access to urologic care. Hospital service areas (HSAs) are where the majority of local patients are hospitalized; hospital referral regions (HRR) are where most patients receive tertiary care. The authors created multivariate hierarchical logistic regression models to examine patient and HSA characteristics associated with the receipt of urologic oncology care out of the HRR for each procedure. RESULTS: Greater than one-half of patients went out of their HRR in 7 HSAs (11%) for radical prostatectomy, 3 HSAs (5%) for radical nephrectomy, 10 HSAs (15%) for PN, and 14 HSAs (22%) for RC. No HSAs had high export rates for TURP. Few patient factors were found to be associated with surgical care out of the HRR. High-export HSAs for PN and RC exhibited lower socioeconomic characteristics than low-export HSAs, adjusting for HSA population, race, and HSA procedure rates for PN and RC. CONCLUSIONS: Patients living in areas with lower socioeconomic status have a greater need to travel for complex urologic surgery. Consideration of geographic delineation in the delivery of urologic oncology care may aid in regional quality improvement initiatives.

Addressing controversial areas in the management of advanced prostate cancer in Canada Areas of consensus and controversy from the third Canadian consensus forum.

INTRODUCTION: The management of prostate cancer (PCa) is rapidly evolving. Treatment and diagnostic options grow annually, however, high-level evidence for the use of new therapeutics and diagnostics is lacking. In November 2022, the Genitourinary Research Consortium held its 3rd Canadian Consensus Forum (CCF3) to provide guidance on key controversial areas for management of PCa. METHODS: A steering committee of eight multidisciplinary physicians identified topics for discussion and adapted questions from the Advanced Prostate Cancer Consensus Conference 2022 for CCF3. Questions focused on management of metastatic castration-sensitive prostate cancer (mCSPC); use of novel imaging, germline testing, and genomic profiling; and areas of non-consensus from CCF2. Fifty-eight questions were voted on during a live forum, with threshold for "consensus agreement" set at 75%. RESULTS: The voting panel consisted of 26 physicians: 13 urologists/uro-oncologists, nine medical oncologists, and four radiation oncologists. Consensus was reached for 32 of 58 questions (one ad-hoc). Consensus was seen in the use of local treatment, to not use metastasis-directed therapy for low-volume mCSPC, and to use triplet therapy for synchronous high-volume mCSPC (low prostate-specific antigen). Consensus was also reached on sufficiency of conventional imaging to manage disease, use of germline testing and genomic profiling for metastatic disease, and poly (ADP-ribose) polymerase (PARP) inhibitors for BRCA-positive prostate cancer. CONCLUSIONS: CCF3 identified consensus agreement and provides guidance on >30 practice scenarios related to management of PCa and nine areas of controversy, which represent opportunities for research and education to improve patient care. Consensus initiatives provide valuable guidance on areas of controversy as clinicians await high-level evidence.

Impact of medical therapy on transurethral resection of the prostate: two decades of change.

OBJECTIVE: • To examine how the introduction of medical therapy for symptomatic benign prostatic hyperplasia (BPH) might have changed the indications, patient characteristics and outcomes in men undergoing transurethral resection of the prostate (TURP) over two decades (1988-2008). PATIENTS AND METHODS: • All patients who underwent TURP for symptomatic BPH in a geographically defined area at our institution in 1988 (before the introduction of medical therapy for BPH), 1998 (when medical therapy was becoming an important therapy for BPH), and 2008 (when medical therapy was the primary first line therapy for BPH) were reviewed. • We assessed the total number of TURPs, indications for surgery, patient age, health status, weight of resected tissue, and pre- and postoperative events/complications. RESULTS: • There was a 60% decrease in TURPs from 1988 to 1998 with a moderate increase in number in 2008. • Failure of medical therapy was not an indication for TURP in 1988, but was at least one of the indications in 36% and 87% of patients in 1998 and 2008, respectively. • There was a substantial rise in the percentage of patients (but not total number or percentage of men at risk for BPH) presenting with acute or chronic urinary retention (AUR or CUR) at the time of their TURP (from 22.9% in 1988 to 42.9% in 2008, and from 14.6% in 1988 to 39.3% in 2008 for AUR and CUR, respectively). There was also a rise in the percentage of patients presenting with preoperative hydronephrosis (1.3% in 1988, 12.5% in 1998, 7.1% in 2008). • Inpatient stays decreased (from 4.1 day in 1988 to 2.7 days in 1998, and to 2.1 day in 2008), but the number of patients discharged with a catheter increased over the two decades (from 3.2% in 1988 to 12.5% in 1998, and to 28.6% in 2008). CONCLUSIONS: • The increasing use of medical therapy as a first line treatment for BPH has resulted in a dramatic decrease in TURPs which, in turn, has been associated with an apparent increase in risk of poor pre- and postoperative outcomes. However, the actual number (either the total number or as a percentage of men at risk for BPH) who have experienced these progression events has not changed and the postoperative outcomes are probably related to earlier catheter removal and hospital discharge. • It appears that we are performing TURP on the right patients.

Treatment and Patient Selection for Patients with Metastatic Castration-resistant Prostate After Progression on Docetaxel and Abiraterone/Enzalutamide: When to Play Your CARD and When to Do Your PARP.

For patients with metastatic castration-resistant prostate cancer (mCRPC) progressing after an androgen receptor axis-targeted therapy and docetaxel, poly (ADP-ribose) polymerase (PARP) inhibitors and chemotherapy with cabazitaxel have shown promise. We address the trials for the two approaches and consider possible sequencing of these drugs. We suggest that only patients with a BRCA2 mutation should receive a PARP inhibitor, and docetaxel or cabazitaxel should be favored in the absence of BRCA2 alterations, provided the patient is naïve to these drugs.

Psychological morbidity associated with prostate cancer: Rates and predictors of depression in the RADICAL PC study.

INTRODUCTION: Across all cancer sites and stages, prostate cancer has one of the greatest median five-year survival rates, highlighting the important focus on survivorship issues following diagnosis and treatment. In the current study, we sought to evaluate the prevalence and predictors of depression in a large, multicenter, contemporary, prospectively collected sample of men with prostate cancer. METHODS: Data from the current study were drawn from the baseline visit of men enrolled in the RADICAL PC study. Men with a new diagnosis of prostate cancer or patients initiating androgen deprivation therapy for prostate cancer for the first time were recruited. Depressive symptoms were evaluated using the nine-item version of the Patient Health Questionnaire (PHQ-9). To evaluate factors associated with depression, a multivariable logistic regression model was constructed, including biological, psychological, and social predictor variables. RESULTS: Data from 2445 patients were analyzed. Of these, 201 (8.2%) endorsed clinically significant depression. Younger age (odds ratio [OR] 1.38, 95% confidence interval [CI] 1.16-1.60 per 10-year decrease), being a current smoker (OR 2.77, 95% CI 1.66-4.58), former alcohol use (OR 2.63, 95% CI 1.33-5.20), poorer performance status (OR 5.01, 95% CI 3.49-7.20), having a pre-existing clinical diagnosis of depression or anxiety (OR 3.64, 95% CI 2.42-5.48), and having high-risk prostate cancer (OR 1.49, 95% CI 1.05-2.12) all conferred independent risk for depression. CONCLUSIONS: Clinically significant depression is common in men with prostate cancer. Depression risk is associated with a host of biopsychosocial variables. Clinicians should be vigilant to screen for depression in those patients with poor social determinants of health, concomitant disability, and advanced disease.

Results from a Canadian consensus forum of key controversial areas in the management of advanced prostate cancer: Recommendations for Canadian healthcare providers.

INTRODUCTION: Rapid progress in diagnostics and therapeutics for the management of prostate cancer (PCa) has created areas where high-level evidence to guide practice is lacking. The Genitourinary Research Consortium (GURC) conducted its second Canadian consensus forum to address areas of controversy in the management of PCa and provide recommendations to guide treatment. METHODS: A panel of PCa specialists discussed topics related to the management of PCa. The core scientific committee finalized the design, questions, and analysis of the consensus results. Attendees then voted to indicate their management choice regarding each statement/topic. Questions for voting were adapted from the 2019 Advanced Prostate Cancer Consensus Conference. The thresholds for agreement were set at ≥75% for "consensus agreement," >50% for "near-consensus," and ≤50% for "no consensus." RESULTS: The panel was comprised of 29 PCa experts, including urologists (n=12), medical oncologists (n=12), and radiation oncologists (n=5). Voting took place for 65 predetermined questions and three ad hoc questions. Consensus was reached for 34 questions, spanning a variety of areas, including biochemical recurrence, treatment of metastatic castration-sensitive PCa, management of non-metastatic and metastatic castration-resistant PCa, bone health, and molecular profiling. CONCLUSIONS: The consensus forum identified areas of consensus or near-consensus in more than half of the questions discussed. Areas of consensus typically aligned with available evidence, and areas of variability may indicate a lack of high-quality evidence and point to future opportunities for further research and education.

Androgen Deprivation Therapy and Mental Health: Impact on Depression and Cognition.

Androgen deprivation therapy (ADT) is a common treatment for many men with prostate cancer. Use of ADT can have significant impacts on the mental health of patients with both localized and advanced disease. Prostate cancer patients receiving ADT have a 41% higher risk of depression and a 47% higher risk of dementia. Risk factors for the development of depression in this group of men include older age, marital status, greater comorbidity, and a previous history of depression, while being retired may offer a protective effect. Optimal treatment strategies for depression for these men are not well established in the literature. PATIENT SUMMARY: We reviewed the association between androgen deprivation therapy (ADT) use by men with prostate cancer and the risk of mental health issues. There appears to be a higher risk of both depression and cognitive impairment for men receiving ADT. Optimal treatments for depression for men on ADT are still not well studied.

Quality of life, depression, and psychosocial mechanisms of suicide risk in prostate cancer.

INTRODUCTION: Prostate cancer (PCa) is the most common non-cutaneous cancer in men and is usually identified at a stage at which prolonged survival is expected. Therefore, strategies to address survivorship and promote well-being are crucial. This study's aim was to better understand suicidal behavior in PCa patients by examining psychosocial mediators (i.e., depression, psychache, perceived burdensomeness [PB], thwarted belongingness [TB]) in the relationship between quality of life (PCa-QoL) and suicide risk. METHODS: Four hundred and six men with PCa (Median age 69.35 years, standard deviation 7.79) completed an online survey on various psychosocial variables associated with suicide risk. A combined serial/parallel mediation model tested whether depression, in serial with both psychache and PB/TB, mediated the relationship between PCa-QoL and suicide risk. RESULTS: Over 14% of participants' self-reports indicated clinically significant suicide risk. Poorer PCa-QoL was related to greater depression, which was related to both greater psychache and PB/TB, which was associated with greater suicide risk. The serial mediation effect of depression and psychache was significantly stronger than that of depression and PB/TB. PCa-QoL did not predict suicide risk through depression alone, showing that depressive symptoms affect suicide risk through psychache and PB/TB. CONCLUSIONS: Given the alarming estimate of individuals at risk for suicide in this study, clinicians should consider patients with poorer PCa-QoL and elevated depression for psychosocial referral or management. Psychache (i.e., psychological pain) and PB/TB (i.e., poor social fit) may be important targets for reducing suicide risk intervention beyond the impact of depression alone.

Controversial issues in the management of patients with advanced prostate cancer: Results from a Canadian consensus forum.

INTRODUCTION: The management of advanced prostate cancer (PCa) continues to evolve with the emergence of new diagnostic and therapeutic strategies. As a result, there are multiple areas in this landscape with a lack of high-level evidence to guide practice. Consensus initiatives are an approach to establishing practice guidance in areas where evidence is unclear. We conducted a Canadian-based consensus forum to address key controversial areas in the management of advanced PCa. METHODS: As part of a modified Delphi process, a core scientific group of PCa physicians (n=8) identified controversial areas for discussion and developed an initial set of questions, which were then reviewed and finalized with a larger group of 29 multidisciplinary PCa specialists. The main areas of focus were non-metastatic castration-resistant prostate cancer (nmCRPC), metastatic castration-sensitive prostate cancer (mCSPC), metastatic castration-resistant prostate cancer (mCRPC), oligometastatic prostate cancer, genetic testing in prostate cancer, and imaging in advanced prostate cancer. The predetermined threshold for consensus was set at 74% (agreement from 20 of 27 participating physicians). RESULTS: Consensus participants included uro-oncologists (n=13), medical oncologists (n=10), and radiation oncologists (n=4). Of the 64 questions, consensus was reached in 30 questions (n=5 unanimously). Consensus was more common for questions related to biochemical recurrence, sequencing of therapies, and mCRPC. CONCLUSIONS: A Canadian consensus forum in PCa identified areas of agreement in nearly 50% of questions discussed. Areas of variability may represent opportunities for further research, education, and sharing of best practices. These findings reinforce the value of multidisciplinary consensus initiatives to optimize patient care.

Canadian Update on Surgical Procedures (CUSP) Urology Group consensus for intraoperative hemostasis during minimally invasive partial nephrectomy.

INTRODUCTION: Partial nephrectomy remains the gold standard in the management of small renal masses. However, minimally invasive partial nephrectomy (MIPN) is associated with a steep learning curve, and optimal, standardized techniques for time-efficient hemostasis are poorly described. Given the relative lack of evidence, the goal was to describe a set of actionable guiding principles, through an expert working panel, for urologists to approach hemostasis without compromising warm ischemia or oncological outcomes. METHODS: A three-step modified Delphi method was used to achieve expert agreement on the best practices for hemostasis in MIPN. Panelists were recruited from the Canadian Update on Surgical Procedures (CUSP) Urology Group, which represent all provinces, academic and community practices, and fellowship-and non-fellowship-trained surgeons. Thirty-two (round 1) and 46 (round 2) panellists participated in survey questionnaires, and 22 attended the in-person consensus meeting. RESULTS: An initial literature search of 945 articles (230 abstracts) underwent screening and yielded 24 preliminary techniques. Through sequential survey assessment and in-person discussion, a total of 11 strategies were approved. These are temporally distributed prior to tumor resection (five principles), during tumor resection (two principles), and during renorrhaphy (four principles). CONCLUSIONS: Given the variability in tumor size, depth, location, and vascularity, coupled with limitations of laparoscopic equipment, achieving consistent hemostasis in MIPN may be challenging. Despite over two decades of MIPN experience, limited evidence exists to guide clinicians. Through a three-step Delphi method and rigorous iterative review with a panel of experts, we ascertained a guiding checklist of principles for newly beginning and practicing urologists to reference.

Depression and prostate cancer: A focused review for the clinician.

Prostate cancer is the most common malignancy among men. Given its prevalence and relatively low mortality rates, several biopsychosocial survivorship issues have garnered recent attention. This article reviews the literature on the association between depression and prostate cancer, emphasizing key practice points relevant for clinicians. Depression is prevalent among men with prostate cancer, with approximately 1 in 6 patients experiencing clinical depression. Suicidal ideation is also not uncommon in this population and does not always present in those with other depressive symptoms. While choice of definitive cancer treatment (radiation or surgery) does not seem to affect depressive symptoms, receipt of androgen deprivation therapy appears to have a negative effect. Not only are patients at increased risk for depression following a prostate cancer diagnosis, but depression itself seems to adversely affect oncologic outcomes. We were not able to identify any clinical trials examining the efficacy of antidepressant medications for depressive symptoms in these patients, however population-based studies suggest antidepressant prescriptions are commonly utilized. Taken together, the literature on the intersection between urologic oncology and psychology/psychiatry affirms the importance of depression among men with prostate cancer. Clinicians should consider assessment of this symptom domain and treat or refer judiciously. Clinical trials represent a priority for future research.

Clinical practice experience with testosterone treatment in men with testosterone deficiency syndrome.

OBJECTIVE: To report on a clinical practice series of testosterone-replacement therapy (TRT) in men with testosterone deficiency syndrome (TDS), examining clinical efficacy, biochemical parameters and effects on prostate health over a 2-year period. PATIENTS AND METHODS: A retrospective review of 85 patients with symptoms of TDS and at least a 3-month trial of TRT was performed in this single-centre, clinical practice setting. Three domains of symptomatology were evaluated: libido, erectile function and energy levels. Symptoms were assessed by a combination of patient reporting, physician's assessment and validated symptom assessment scores. Total testosterone (TT), calculated bio-available testosterone (BT) and prostate-specific antigen (PSA) levels were continuously measured and effects on prostate health were examined. RESULTS: Only 38 (45%) patients in this cohort remained on TRT for >2 years. The most common reason for discontinuing treatment was lack of clinical response but those remaining on TRT had continued improvement in libido, erectile function and energy levels. During treatment, the average TT and calculated BT values significantly increased compared with the baseline values at most of the evaluated time points, with no significant change in average PSA values. In all, 15% of this cohort had some degree of progression of lower urinary tract symptoms. Seven patients had eight 'for-cause' prostate biopsies either during supplementation or at any date after completion, with an only three positive for cancer. CONCLUSIONS: Only 45% of men on TRT remained on treatment for >2 years in this clinical practice experience of men with TDS. Those remaining showed persistent improvement in their symptoms. The average TT and BT values increased significantly with no significant change in PSA levels.

Biopsychosocial impact of prostate cancer and androgen-deprivation therapy.

INTRODUCTION: Prostate cancer is the most non-cutaneous malignancy in men, and androgen-deprivation therapy (ADT) is a cornerstone of management in advanced disease. The aim of this study was to evaluate the association of ADT with changes in depression and mental and physical quality of life (QoL) within a prospective patient cohort design. METHODS: Patients were prospectively recruited and consented at a single academic health sciences centre in Ontario, Canada. Inclusion criteria included those men with adenocarcinoma of the prostate and either on watchful waiting or initiating ADT as palliation or as an adjuvant therapy for high-risk localized disease. All three cohorts were followed in routine care and completed psychosocial evaluations, including depression, social support, anxiety, and QoL measures. RESULTS: In comparison to the control cohort of patients with prostate cancer on watchful waiting, initiation of ADT over a two-year period of time was not associated with any changes in depression or mental QoL. Instead, all patients, regardless of treatment cohort, showed increased depression scores and reduced mental QoL scores over time; however, for patients receiving ADT, a significant reduction in physical QoL compared to patients who did not receive ADT was demonstrated. CONCLUSIONS: ADT does not appear to significantly impact depressive symptoms and mental QoL over a two-year period; however, the depressive symptoms in this limited sample of men with prostate cancer was higher than expected and monitoring for these may be advisable for those who care for such patients.
