The role of multiparametric ultrasound in the detection of clinically significant prostate cancer.

PURPOSE: Transrectal ultrasound (US) imaging is paramount to the successful completion of prostate biopsies. Certain US features have been associated with prostate cancer (PCa), but their utility remains controversial. We explored the role of multiparametric US (mpUS) in the detection of clinically significant PCa. METHODS: We performed a retrospective cohort study to contrast the findings of prostate MRI and mpUS. Patients who underwent MRI, US and biopsy between 2015 and 2021 were included. Biopsies were performed using a systematic approach (12 cores), as well as with MRI (4 cores/lesion) and US (1 core/lesion) targeting. The US features analyzed consisted of: calcifications, hypoechoic lesions and power or color Doppler positivity. Gleason 3 + 4 or higher was used as to define true positives. Measures of diagnostic accuracy were calculated for the different imaging modalities. RESULTS: The final cohort included 74 patients, of which 24 (32.4%) had clinically significant PCa. The concordance between MRI and US was 63.5%. Seven individuals with discordant results had clinically significant PCa. MRI alone was more sensitive (87.5% vs 75%) but less specific (28% vs 32%) than US alone. An all-inclusive approach considering any suspicious US or MRI finding had a sensitivity of 95.8%. A more restrictive approach, targeting lesions noted in both US and MRI, yielded the highest specificity (50.0%) and accuracy (55.4%). CONCLUSION: Biopsy targeting based on US findings can provide additional diagnostic information that may increase sensitivity or specificity. Additional research into this topic could open the door to a more personalized approach to prostate biopsy.

Prospective quality of life in men choosing open vs. robotic radical prostatectomy: long-term results from a racially diverse multi-institutional database.

PURPOSE: To compare 5-year health-related quality of life (HRQoL) outcomes between prostate cancer (CaP) patients who underwent robotic-assisted laparoscopic radical prostatectomy (RALP) versus open radical retropubic prostatectomy (RRP) and assess for racial disparities between Caucasian American (CA) and African American (AA) men undergoing surgery. METHODS: A prospective cohort study of HRQoL data was conducted on patients diagnosed with CaP from 2007 to 2017 and enrolled in the Center for Prostate Disease Research (CPDR) Multicenter National Database. Using the EPIC and SF-36 instruments, changes in urinary, sexual, bowel, and hormonal domains, as well as physical and mental component summary scores were compared across surgery type (RALP versus RRP) at pre-treatment ("baseline"), and annually for 5 years. We further compared HRQoL outcomes in CA and AA men undergoing surgery. Longitudinal HRQoL patterns were modeled using generalized estimating equations (GEE), adjusting for baseline HRQoL and other characteristics. RESULTS: 448 CaP patients (22% AA) met study inclusion criteria, 66% underwent RALP and 34% underwent RRP. At baseline, HRQoL domains were comparable across treatment group (RALP vs. RRP). In the adjusted low-risk cohort, there were only three time points that met a statistically significant HRQoL difference in EPIC scores between RALP and RRP. Urinary function score during year 4 of follow-up showed a 7.5 (95% CI 3.1-11.9, P = 0.01) points difference in favor of RRP. Bowel bother scores favored RRP in year 1 with a difference of 3.1 (95% CI 0.7-5.4, P = 0.04) points, and in year 5 with a difference of 3.8 (95% CI 1.1-6.4, P = 0.03) points. In the intermediate/high-risk cohort, there were no statistically significant differences in any of the domain scores between RALP and RRP during follow-up. CONCLUSIONS: The robotic and open approach to radical prostatectomy led to comparable HRQoL outcomes at a follow-up length of 60 months. No HRQoL racial disparities were found between AA and CA men during long-term follow-up.

National Comprehensive Cancer Network® Favorable Intermediate Risk Prostate Cancer-Is Active Surveillance Appropriate?

PURPOSE: We compared pathological and biochemical outcomes after radical prostatectomy in patients at favorable intermediate risk who fulfilled current NCCN® (National Comprehensive Cancer Network®) Guidelines® for active surveillance criteria to outcomes in patients who met more traditional criteria for active surveillance. MATERIALS AND METHODS: We queried our institutional review board approved prostate cancer database for patients who met NCCN criteria for very low risk (T1c, Grade Group 1, 3 or fewer of 12 cores, 50% or less core volume and prostate specific antigen density less than 0.15 ng/ml), low risk (T1-T2a, Grade Group 1 and prostate specific antigen less than 10 ng/ml) or favorable intermediate risk (major pattern grade 3 and less than 50% positive biopsy cores) and who had 1 intermediate risk factor, including T2b/c, Grade Group 2 or prostate specific antigen 10 to 20 ng/ml. Men at intermediate risk who did not meet favorable criteria were labeled as being at unfavorable intermediate risk. Patients at favorable intermediate risk were compared to those at very low and low risk, and those at unfavorable intermediate risk to identify differences in rates of adverse pathological findings at radical prostatectomy, including Gleason score Grade Group 3-5, nonorgan confined disease or nodal involvement. Time to biochemical recurrence was compared among the groups using Cox regression. RESULTS: A total of 3,686 patients underwent radical prostatectomy between January 1, 2014 and December 31, 2015. Of these men 1,454, 250 and 1,362 fulfilled the criteria for low, favorable intermediate and unfavorable intermediate risk, respectively. The rate of adverse pathological findings in favorable intermediate risk cases was significantly higher than in low risk cases and significantly lower than in unfavorable intermediate risk cases (27.4% vs 14.8% and 48.5%, respectively, each p <0.001). Time to biochemical recurrence differed significantly among the risk groups (p <0.001). CONCLUSIONS: Relative to men at low risk those at favorable intermediate risk represent a distinct group. Care should be taken when selecting these patients for active surveillance and monitoring them once they are in an active surveillance program.

Is Tamsulosin Linked to Dementia in the Elderly?

PURPOSE OF REVIEW: Lower urinary tract symptoms (LUTS) result from age-related changes in detrusor function and prostatic growth that are driven by alterations in the ratio of circulating androgens and estrogens. Alpha-adrenergic receptor blockers are commonly used to treat LUTS because they influence urethral tone and intra-urethral pressure. Molecular cloning studies have identified three α1-adrenergic receptor subtypes (α1A, α1B, and α1D). The α1A subtype is predominant in the human prostate but is also present in many parts of the brain that direct cognitive function. Tamsulosin is the most widely used α1-adrenergic receptor antagonist with 12.6 million prescriptions filled in 2010 alone. When compared to the other common types of α1-adrenergic receptor antagonists (i.e., terazosin, doxazosin, and alfuzosin), tamsulosin is 10- to 38-fold more selective for the α1A versus the α1B subtype. RECENT FINDINGS: Duan et al. have recently shown that men taking tamsulosin have a higher risk of developing dementia when compared to men taking other α-adrenergic antagonists or no α-adrenergic antagonists at all (HR 1.17; 95% CI 1.14-1.21). Based upon this retrospective analysis, we believe that tamsulosin, because of its unique affinity for α1A-adrenergic receptors, may increase the risk of developing dementia when used for an extended period of time. If these findings are confirmed, they carry significant public health implications for an aging society.

Multiple intra-renal artery aneurysms causing renal obstruction managed with radical nephrectomy.

A 46-year-old male with a history of hypertension presented with symptoms of persistent abdominal fullness and a non-pulsatile abdominal mass. Subsequent computed tomographic angiography studies revealed the presence multiple large renal aneurysms from the segmental branches of the renal artery and an enlarged hydronephrotic kidney with minimal parenchyma. The renal deterioration appeared to be as a result of an obstruction caused by the large intra-renal aneurysms at the level of the renal calyces. Since the right kidney had no function, an open radical nephrectomy was subsequently performed without complications at 3 months follow up.

Coadministration of anastrozole sustains therapeutic testosterone levels in hypogonadal men undergoing testosterone pellet insertion.

INTRODUCTION: Current U.S. Food and Drug Administration-approved therapies for hypogonadism involve testosterone (T) replacement. Testosterone pellets (TP) require a minor office procedure every 3 to 4 months. The need for repeated insertions increases the likelihood of a complication. Anastrozole (AZ) is an aromatase inhibitor that has been used off-label for the treatment of male hypogonadism. AZ increases T levels by lowering serum estradiol (E2) levels and increasing gonadotropin (GTP) levels. AIM: We hypothesized that the concomitant use of AZ with TP insertions would sustain therapeutic T levels and increase the interval between TP insertions. METHODS: Men treated with TP for hypogonadism at an academic center were offered AZ (1 mg/day) at the time of TP reinsertion as a way of potentially decreasing the frequency of TP insertions. Total T (TT), free T (FT), sex hormone binding globulin, E2, luteinizing hormone (LH), and follicle-stimulating hormone FSH levels were obtained prior to T replacement and at 6 and 15 weeks from TP insertion. Men were re-implanted at 16 weeks if their TT levels were less than 350 ng/dL and their symptoms recurred. We retrospectively reviewed our records of men who underwent TP, TP, and AZ from 2011 to 2012. Demographics, TT, FT, LH, FSH, and E2 levels were recorded. Data were analyzed with anova and a Tukey's test. MAIN OUTCOME MEASURE: TT level at 6, 15, or >15 weeks from TP insertion. RESULTS: Thirty-eight men with 65 insertions were analyzed. The TP AZ group had significantly higher TT and FT levels than the TP group at >120 days (P < 0.05). The TP group had significantly higher E2 levels at all time points (P < 0.01). GTP levels remained stable in the TP AZ group. Average time to reinsertion in TP AZ was 198 days vs. 128 days in the TP group. CONCLUSION: Men on TP AZ maintain therapeutic T levels longer than men on TP alone and have significantly less GTP suppression.

Are high-risk prostate cancer patients being treated equally? The impact of PSA.

BACKGROUND: Patients with high-risk (HR) prostate cancer (PCa) represent a heterogeneous group, however, current treatment guidelines do not consider their specific features. The objective of this study was to evaluate treatment trends and outcomes in HR patients defined by PSA alone and otherwise low-risk features. METHODS: Using the National Cancer Database, we identified patients diagnosed with HR PCa between 2010 and 2016. A study group of patients defined by PSA >20 ng/ml alone and otherwise low-risk features, was compared to a group of HR patients defined by Gleason score or stage. We compared treatment rates over time, the use of concomitant androgen deprivation therapy (ADT), and overall survival (OS). Examination of treatment trends was done using a Z-test analysis. A Kaplan-Meier survival analysis was used to determine 5-year OS with the Log-rank test for comparison. Statistical analyses were completed using R Version 3.5.2. RESULTS: We identified 5,652 patients in the study group and 71,922 in the comparison group. Only 6.8% of the study group had disease ≥cT2, compared to 43.7% in the comparison group. In the study group, 12.5% (709), underwent active surveillance (AS), 36.4% (2,055) radiation therapy (EBRT) and 51.1% (2,888) radical prostatectomy (RP), while the rate of AS, EBRT, and RP in the comparison group were 0.3% (191), 43.0% (30,928), and 56.7% (40,803), respectively. Over the study period, adoption of AS increased from 6.2% in 2010 to 25.0% in 2016 in the study group (P< 0.001), but not in the comparison group. In patients undergoing EBRT, ADT treatment increased from 2010 to 2016 in both groups, though by 2016 only 45.3% of patients in the study group and 86.3% in the comparison group received ADT. The 5-year OS was 93.7% (95% CI 92.8-94.6) in the study group and 89.7% (95% CI 89.2-90.1) in the comparison group (P< 0.001). CONCLUSIONS: Men with HR PCa defined by PSA with otherwise low risk features present at an earlier stage and receive less aggressive therapy than other HR patients. Despite increased rates of AS and decreased use of ADT, these patients appear to have improved survival when compared to other HR patients. These findings suggest that not all HR patients will benefit from aggressive definitive treatment.

Impact of Age and Race on Health-Related Quality of Life Outcomes in Patients Undergoing Radical Prostatectomy for Localized Prostate Cancer.

OBJECTIVES: To investigate impact of age and race on health-related quality of life (HRQoL) in men undergoing radical prostatectomy (RP) using a prospectively maintained, racially diverse cohort. METHODS: The Center for Prostate Disease Research Multicenter National Database was used to identify patients receiving RP from 2007-2017. The Expanded PCa Index Composite and 36 Item Short-Form Health Survey were completed at baseline and regular intervals. Groups were stratified based on age: <60, 60-70, >70. Longitudinal patterns in HRQoL were assessed using linear regression models, adjusting for baseline HRQoL, demographics, and clinical characteristics. RESULTS: In 626 patients undergoing RP, 278 (44.4%) were <60, 291 (46.5%) were 60-70, 57 (9.1%) were >70. Older men had worse baseline urinary bother (P<.01) and sexual HRQoL (P<.01). Baseline urinary function was similar for older and younger men. Post-RP urinary and sexual HRQoL was significantly lower in men >70. However, when adjusting for baseline HRQoL, race, NCCN risk, and comorbidities, no difference was found between age groups in urinary function or bother, or sexual function. Sexual bother was worse in older men until 48 months post-operatively but subsequently improved to levels similar to younger patients. Race independently affected HRQoL outcomes with older African American men reporting worse urinary function and sexual bother. CONCLUSIONS: When accounting for baseline HRQoL, age does not independently predict worse HRQoL outcomes. Older and younger men experience similar declines in urinary and sexual domain scores after RP. Our findings may be used to better inform patients regarding their expected post RP HRQoL and guide treatment decision-making.

Type and Screen Prior to Radical Prostatectomy for Prostate Cancer- Time for a Change?

PURPOSE: Despite low rates of transfusion associated with robotic prostatectomy, surgeons routinely obtain preoperative blood typing. Here we aim to understand the cost savings associated with eliminating blood typing prior to prostatectomy. MATERIALS AND METHODS: A retrospective review of our single surgeon radical prostatectomy database was performed. Patients receiving blood transfusions within 3 days of prostatectomy were identified and clinical characteristics were recorded. Cost information was obtained, and descriptive statistical analysis performed. RESULTS: 1,581 patients underwent prostatectomy from 2000 to 2019. Thirty-two patients (2.02%) received a transfusion within 3 days of surgery. The transfusion rate for open prostatectomy was 3.21% vs 1.37% for robotic prostatectomy. The cost of preoperative blood typing for all radical prostatectomies was $113,832, or about $5,812.70 per year. CONCLUSIONS: Transfusion rates for prostatectomy are low and decline with experience. Significant cost savings is possible by avoiding routine preoperative blood typing in most patients undergoing radical prostatectomy.

Anti-Tobacco Advertising-Is Bladder Cancer Adequately Addressed?

INTRODUCTION: In order to assess whether bladder cancer is appropriately referenced in online anti-tobacco advertisements, we evaluated 200 videos and assessed diseases mentioned in these videos. This was then compared to relative incidence of tobacco-associated malignancy. METHODS: Smoking cessation campaign videos were identified using the Google Video search page. The first 50 video results of 4 colloquial search terms were assessed for diseases mentioned. Videos were categorized as malignancy-related anti-tobacco advertisement or all anti-tobacco advertisement. Relative weight for each tobacco-associated malignancy was defined as the rate of reference within malignancy-related anti-tobacco advertisements divided by the incidence of that cancer among all smoking-related malignancies. RESULTS: In all, 200 total videos were reviewed. The most common conditions highlighted were addiction (56, 27.0%) and death (26, 13.0%). The most common malignancies addressed were lung cancer (22, 11.0%), throat cancer (20, 10.0%) and oral cancer (9, 4.5%). Only 1 (0.5%) video mentioned bladder cancer. The relative weights of each malignancy were: lung cancer 1.09, oral cancer 18.26, throat cancer 1.94, bladder cancer 0.14. CONCLUSIONS: This study demonstrates the significant opportunity that exists for public education regarding the relationship between tobacco use and bladder cancer. Despite a relatively high incidence amongst tobacco-associated malignancies, bladder cancer is very poorly represented in anti-tobacco advertising with a relative weight of 0.14. It is possible that a more representative presentation of the adverse effects of tobacco use would be more efficacious in promoting tobacco cessation.

Contemporary trends in management of stage 1 seminoma.

PURPOSE: Surveillance is now the preferred treatment strategy for patients with stage 1A/1B seminoma as reflected by the National Comprehensive Cancer Network guidelines. In this study, we aimed to describe trends in adjuvant management strategy for stage 1A/B seminoma from 2004 to 2016 using the National Cancer Database. MATERIALS AND METHODS: The database was queried for patients diagnosed with stage 1A/1B seminoma between 2004 and 2016. Staging was determined using the American Joint Committee on Cancer guidelines. Surveillance was defined as no treatment with chemotherapy or radiation within 60 days of diagnosis. Proportions of cancer patients utilizing surveillance, radiation, and single-agent chemotherapy were summarized annually. Kaplan-Meier survival analysis was used to compare overall survival between groups. RESULTS: 8,686 patients with stage 1A/1B seminoma met inclusion criteria over the course of the study period. Overall, 3,004 (34.6%) patients began adjuvant chemotherapy or radiation within 60 days. Utilization of surveillance increased from 39.8% in 2004 to 86.8% in 2016 while utilization of radiation decreased from 59.7% to 4.6%. High-volume centers adopted surveillance earlier than low-volume centers. CONCLUSION: This study describes trends in utilization of surveillance, chemotherapy, and radiotherapy for stage 1A/1B seminoma over 12 years. A major shift from utilization of adjuvant treatment to surveillance in patients with stage 1A/B seminoma is observed in this large national cancer database; a minority of patients now receive adjuvant treatment and risk-related toxicities. Survival analysis reveals similar survival at a median 5-year follow-up. The results provide insight into the time needed for clinical practice to adopt the preferred approach of surveillance over the time period studied.

Combined chemotherapy and radiotherapy improves survival in 1897 testicular Lymphoma patients from a contemporary cohort.

INTRODUCTION: The standard of care (SOC) for primary testicular lymphoma (PTL) is orchiectomy, chemotherapy (CHT), and radiotherapy (RT). We hypothesized that men may not receive SOC and may have worse outcomes. To assess this, we queried the National Cancer Database (NCDB) to analyze treatment patterns and survival in PTL patients. METHODS: The NCDB was queried (2006-2016) for men diagnosed with extranodal lymphoma with primary site testis. Patients were placed in 2 treatment groups (1) orchiectomy with chemotherapy plus radiotherapy (CHT + RT), named the SOC group; and 2) CHT + orchiectomy, or RT + orchiectomy, or orchiectomy alone, grouped as non-SOC. Propensity score matching and Kaplan-Meier analysis were used to investigate 5-year overall survival (OS). RESULTS: Two thousand two hundred thirty-two men with PTL underwent orchiectomy. After exclusions, 891 men were included in the SOC group and 1,006 men were included in the non-SOC group. KM analysis showed 5-year OS was significantly higher in the SOC group vs. non-SOC for all stages (hazard ratio = 0.54, with 95% confidence interval 0.45 to 0.65, P < 0.0001). CONCLUSIONS: This study represents one of the largest PTL cohort reported to date reflecting current treatments and shows men receiving standard of care treatment have significantly improved survival. Additionally, analysis reveals that most men included in the NCDB do not receive the standard of care.

Caprini score and surgical times linked to the risk for venous thromboembolism after robotic-assisted radical prostatectomy.

OBJECTIVE: To evaluate the Caprini score as an independent predictor of venous thromboembolism (VTE) in patients undergoing robotic-assisted radical prostatectomy (RARP) and to identify appropriate cut-points for clinical use. MATERIAL AND METHODS: We performed a retrospective review of patients who underwent RARP for prostate cancer between December 2003 and February 2016. VTE cases developed the condition within 90 days of discharge. The control group was comprised of patients whose RARP most closely preceded and followed each VTE case in time and who were matched on lymph node dissection and surgeon. The Caprini score was calculated for each patient, and the groups were compared on a number of clinical variables. Multiple logistic regression was used to evaluate whether the Caprini score was an independent predictor of VTE. Receiver operating characteristics (ROC) curves were used to establish appropriate clinical cutpoints. RESULTS: A total of 3719 patients underwent RARP during the study period. A total of 52 (1.4%) of patients met the criteria for cases. Data were available for 97 patients who met the criteria for controls. Multiple logistic regression indicated that the Caprini score and operative time were independently both significant predictors of VTE (p=0.005 and p=0.044, respectively). ROC indicated that the Caprini score showed a significant but moderate relationship to VTE (area under curve [AOC]=0.64; p=0.004). A Caprini score >6 was the best arithmetic balance for sensitivity (61.5; 95% confidence interval [CI]: 47.0-74.7) and specificity (59.8; 95% CI: 49.3-69.6). CONCLUSION: The Caprini score predicts postoperative VTE in patients undergoing RARP.

Incidence of Skin and Respiratory Immune-Related Adverse Events Correlates With Specific Tumor Types in Patients Treated With Checkpoint Inhibitors.

Checkpoint inhibitors (CPIs) increase antitumor activity by unblocking regulators of the immune response. This action can provoke a wide range of immunologic and inflammatory side effects, some of which can be fatal. Recent studies suggest that CPI-induced immune-related adverse events (irAEs) may predict survival and response. However, little is known about the mechanisms of this association. This study was undertaken to evaluate the influence of tumor diagnosis and preexisting clinical factors on the types of irAEs experienced by cancer patients treated with CPIs. The correlation between irAEs and overall survival (OS) was also assessed. All cancer patients treated with atezolizumab (ATEZO), ipilimumab (IPI), nivolumab (NIVO), or pembrolizumab (PEMBRO) at Virginia Mason Medical Center between 2011 and 2019 were evaluated. irAEs were graded according to the Common Terminology Criteria for Adverse Events (Version 5) and verified independently. Statistical analyses were performed to assess associations between irAEs, pre-treatment factors, and OS. Of the 288 patients evaluated, 59% developed irAEs of any grade, and 19% developed irAEs of grade 3 or 4. A time-dependent survival analysis demonstrated a clear association between the occurrence of irAEs and OS (P < 0.001). A 6-week landmark analysis adjusted for body mass index confirmed an association between irAEs and OS in non-Small Cell Lung Cancer (NSCLC) (P < 0.03). An association between melanoma and skin irAEs (P < 0.01) and between NSCLC and respiratory irAEs (P = 0.03) was observed, independent of CPI administered. Patients with preexisting autoimmune disease experienced a higher incidence of severe irAEs (P = 0.01), but not a higher overall incidence of irAEs (P = 0.6). A significant association between irAEs and OS was observed in this diverse patient population. No correlation was observed between preexisting comorbid conditions and the type of irAE observed. However, a correlation between skin-related irAEs and melanoma and between respiratory irAEs and NSCLC was observed, suggesting that many irAEs are driven by a specific response to the primary tumor. In patients with NSCLC, the respiratory irAEs were associated with a survival benefit.

Weekend Admission to Inpatient Rehabilitation Facilities Is Associated With Transfer to Acute Care in a Nationwide Sample of Patients With Stroke.

OBJECTIVE: The aim of the study was to determine the impact of weekend versus weekday admission to an inpatient rehabilitation facility on the risk of acute care transfer in patients with stroke. DESIGN: This was a retrospective analysis using the Uniform Data System for Medical Rehabilitation, a national database comprising data from 70% of US inpatient rehabilitation facilities. A total of 1,051,436 adult (age ≥18 yrs) stroke cases were identified between 2002 and 2014 that met inclusion criteria. Logistic regression models were developed to test for associations between weekend (Friday-Sunday) versus weekday (Monday-Thursday) inpatient rehabilitation facility admission and transfer to acute care (primary outcome) and inpatient rehabilitation facility length of stay (secondary outcome), adjusting for relevant patient, medical, and facility variables. A secondary analysis examined acute care transfer from 2002 to 2009 before passage of the Affordable Care Act (ACA), 2010 to 2012 post-Affordable Care Act, and 2013 to 2014 after implementation of the Hospital Readmissions Reduction Program. RESULTS: Weekend inpatient rehabilitation facility admission was associated with increased odds of acute care transfer (odds ratio = 1.06, 95% confidence interval = 1.04-1.08) and slightly shorter inpatient rehabilitation facility length of stay (P < 0.001). Overall, the risk of acute care transfer decreased after the ACA and Hospital Readmissions Reduction Program. CONCLUSIONS: Weekend admission to inpatient rehabilitation facility may pose a modest increase in the risk of transfer to acute care in patients with stroke.

A prospective analysis of health-related quality of life in intermediate and high-risk prostate cancer patients managed with intensity modulated radiation therapy, with vs. without hormonal therapy.

INTRODUCTION: Combined radiotherapy and hormonal treatment are recommended for intermediate- and high-risk prostate cancer (CaP). This study compared the long-term effects on health-related quality of life (HRQoL) of intermediate- and high-risk CaP patients managed with radiation therapy (RT) with vs. without hormone therapy (HT). METHODS: Patients with intermediate- and high-risk CaP enrolled in the Center for Prostate Disease Research diagnosed from 2007 to 2017 were included. EPIC and SF-36 questionnaires were completed and HRQoL scores were compared for patients receiving RT vs. RT + HT at baseline (pretreatment), 6, 12, 24, 36, 48, and 60 months after CaP diagnosis. Longitudinal patterns of change in HRQoL were modeled using linear regression models, adjusting for baseline HRQoL, age at CaP diagnosis, race, comorbidities, National Comprehensive Cancer Network (NCCN) risk stratum, time to treatment, and follow-up time. RESULTS: Of 164 patients, 93 (56.7%) received RT alone and 71 (43.3%) received RT + HT. Both groups reported comparable baseline HRQoL. Patients receiving RT+HT were more likely to be NCCN high risk as compared to those receiving only RT. The RT + HT patients experienced worse sexual function, hormonal function, and hormonal bother than those who only received RT; however, HRQoL recovered over time for the RT + HT group. No significant differences were observed between groups in urinary and bowel domains or SF-36 mental and physical scores. CONCLUSION: Combined RT + HT treatment was associated with temporary lower scores in sexual and hormonal HRQoL compared with RT only. Intermediate- and high-risk CaP patients should be counseled about the possible declines in HRQoL associated with HT.

International volunteerism and urethral stricture disease: a review.

Global health is an ever-expanding area of interest for many healthcare workers around the world. In recent years, it has become apparent that much of the global disease burden is surgical. Urologic disease is no exception-many international organizations send volunteers around the world to support Urologic services in countries that lack capacity and resources. Urethral stricture represents a unique opportunity for specialized surgical management that vastly improves long term morbidity. Here we review the prevalence, etiology, and management of urethral stricture from a global perspective while highlighting impact of international urologic volunteer efforts.

Long term mortality in critically ill burn survivors.

INTRODUCTION: Little is known about long term survival risk factors in critically ill burn patients who survive hospitalization. We hypothesized that patients with major burns who survive hospitalization would have favorable long term outcomes. METHODS: We performed a two center observational cohort study in 365 critically ill adult burn patients who survived to hospital discharge. The exposure of interest was major burn defined a priori as >20% total body surface area burned [TBSA]. The modified Baux score was determined by age + %TBSA+ 17(inhalational injury). The primary outcome was all-cause 5year mortality based on the US Social Security Administration Death Master File. Adjusted associations were estimated through fitting of multivariable logistic regression models. Our final model included adjustment for inhalational injury, presence of 3rd degree burn, gender and the acute organ failure score, a validated ICU risk-prediction score derived from age, ethnicity, surgery vs. medical patient type, comorbidity, sepsis and acute organ failure covariates. Time-to-event analysis was performed using Cox proportional hazard regression. RESULTS: Of the cohort patients studied, 76% were male, 29% were non white, 14% were over 65, 32% had TBSA >20%, and 45% had inhalational injury. The mean age was 45, 92% had 2nd degree burns, 60% had 3rd degree burns, 21% received vasopressors, and 26% had sepsis. The mean TBSA was 20.1%. The mean modified Baux score was 72.8. Post hospital discharge 5year mortality rate was 9.0%. The 30day hospital readmission rate was 4%. Patients with major burns were significantly younger (41 vs. 47 years) had a significantly higher modified Baux score (89 vs. 62), and had significantly higher comorbidity, acute organ failure, inhalational injury and sepsis (all P<0.05). There were no differences in gender and the acute organ failure score between major and non-major burns. In the multivariable logistic regression model, major burn was associated with a 3 fold decreased odds of 5year post-discharge mortality compared to patients with TBSA<20% [OR=0.29 (95%CI 0.11-0.78; P=0.014)]. The adjusted model showed good discrimination [AUC 0.81 (95%CI 0.74-0.89)] and calibration (Hosmer-Lemeshow χ2 P=0.67). Cox proportional hazard multivariable regression modeling, adjusting for inhalational injury, presence of 3rd degree burn, gender and the acute organ failure score, showed that major burn was predictive of lower mortality following hospital admission [HR=0.34 (95% CI 0.15-0.76; P=0.009)]. The modified Baux score was not predictive for mortality following hospital discharge [OR 5year post-discharge mortality=1.00 (95%CI 0.99-1.02; P=0.74); HR for post-discharge mortality=1.00 (95% CI 0.99-1.02; P=0.55)]. CONCLUSIONS: Critically ill patients with major burns who survive to hospital discharge have decreased 5year mortality compared to those with less severe burns. ICU Burn unit patients who survive to hospital discharge are younger with less comorbidities. The observed relationship is likely due to the relatively higher physiological reserve present in those who survive a Burn ICU course which may provide for a survival advantage during recovery after major burn.
