Reproductive Urology Consultation Is an Opportunity to Evaluate for Medical Comorbidity: The Prevalence of Elevated Blood Pressure and Obesity at Fertility Evaluation.

Purpose To evaluate the prevalence of elevated blood pressure (EBP), hypertension (HTN), and obesity among men presenting for fertility evaluation. Methods We retrospectively evaluated all men presenting for male infertility consultation at a single institution from 2000 to 2018. Blood pressure (BP) measurements were abstracted from the electronic health record, and EBP/HTN was defined according to American Heart Association/American College of Cardiology guidelines (systolic blood pressure (SBP) ≥ 120 mmHg or diastolic blood pressure (DBP) ≥ 80 mmHg). Descriptive statistics were used to compare demographic and clinical characteristics of men with and without EBP/HTN or obesity (BMI ≥ 30 kg/m2), and logistic regression was utilized to determine associations with EBP/HTN. Results Among 4,127 men, 1,370 (33.2%) had a recorded SBP and DBP within one year of their initial visit. EBP/HTN was noted in 857 (62.6%) men. A total of 249 (18.2%) men were obese, 863 (63.0%) were non-obese, and 258 (18.8%) did not have BMI recorded. HTN and obesity were jointly present in 195 (17.5%) men. There was no significant difference in age, ethnicity, or total motile sperm count between men with and without EBP/HTN. On multivariable analysis, BMI was significantly associated with EBP/HTN (OR: 1.13, 95% CI: 1.08-1.18, p < 0.001). Conclusion More than half of men presenting for initial fertility consultation have either EBP, obesity, or both. Reproductive urologists should consider routinely screening for these conditions and encourage men to seek further evaluation and treatment, when appropriate.

Hypogonadism, frailty, and postoperative outcomes among men undergoing radical nephrectomy.

BACKGROUND AND OBJECTIVE: Hypogonadism and frailty may impact postoperative outcomes for men undergoing radical nephrectomy (RN). We aimed to determine the prevalence of hypogonadism in men undergoing RN and whether hypogonadism and frailty are associated with adverse postoperative outcomes. METHODS: We identified men undergoing RN between 2012 and 2021 using the IBM Marketscan database. Frailty was determined using the Hospital Frailty Risk Score (HFRS). Patients were considered to have hypogonadism if diagnosed <5 years before RN. Length of stay (LOS), complications, emergency department (ED) visits, and readmissions were evaluated between men with and without hypogonadism at the time of surgery. Subgroup analysis of men with hypogonadism was performed to determine the effect of testosterone replacement therapy (TRT) on clinical outcomes. RESULTS: Among 13 598 men who underwent RN, 972 (7.1%) had hypogonadism. Men with hypogonadism were more frail compared to men without hypogonadism (HFRS: median: 8.2, interquartile range [IQR]: 5.2-11.7 vs. median: 7.0, IQR: 4.3-10.7, p < 0.001) and had increased incidence of postoperative ileus (13.0% vs. 10.8%, p = 0.045), acute kidney injury (25.5% vs. 21.6% p = 0.005), and cardiac arrest (1.2% vs. 0.6%, p = 0.034). Hypogonadism was not associated with LOS, 90-day ED visit or readmission. However, high-risk frailty was associated with increased risk of 90-day ED visit (hazard ratio [HR]: 2.1, 95% confidence interval [95% CI]: 1.9-2.4, p < 0.001) and 90-day inpatient readmission (HR: 2.6, 95% CI: 2.2-3.1, p < 0.001), compared to low-risk frailty patients. Among men with hypogonadism, TRT was not associated with any postoperative outcomes. CONCLUSIONS: Hypogonadism and frailty should be considered in the preoperative evaluation for men undergoing RN as risk factors for adverse postoperative outcomes.

Novel reference range values for serum testosterone: a cross-sectional study of 200,000 males.

PURPOSE: To better understand the effects of aging, metabolic syndrome, diurnal variation, and seasonal variation on serum testosterone levels in the context of current guideline statements on testosterone deficiency. METHODS: This cross-sectional study utilized the United Kingdom Biobank. Physical examination, anthropomorphic measurements, and laboratory evaluation were performed at the time of enrollment from 2006 to 2010. The primary outcomes were the effect of age, the presence of metabolic syndrome, the time of day, and the month of the year on serum testosterone levels. RESULTS: Among 197,883 included men, the 5th, 25th, 50th, 75th and 95th percentile testosterone levels in men without metabolic syndrome were significantly higher than those in men with metabolic syndrome at every decade of life (p < 0.001). The average testosterone level within each group (men without metabolic syndrome vs. men with) was clinically similar across decade of life (12.43 in 40's 12.29 in 50's 12.24 in 60's vs. 10.69 in 40's 10.56 in 50's 10.63 in 60's respectively). Average testosterone levels decreased with blood draws later in the day ranging from 10.91 to 12.74 nmol/L (p < 0.01). Similarly, there was seasonal variation in serum testosterone ranging from 11.86 to 12.18 nmol/L (p < 0.01). CONCLUSIONS: We found significant variation in serum testosterone according to the presence of metabolic syndrome and time of laboratory draw, but not according to age. These data challenge the prior dogma of age-related hypogonadism and favor an individualized approach towards serum testosterone measurement and interpretation. However, further studies are needed to correlate these population-based data with individuals' hypogonadal symptoms.

The association between frailty, hypogonadism, and postoperative outcomes among men undergoing radical cystectomy.

INTRODUCTION: Hypogonadism is associated with frailty, lower health-related quality of life, decreased muscle mass, and premature mortality, which may predispose patients to poor postoperative outcomes. We aimed to determine the prevalence of hypogonadism in men undergoing radical cystectomy (RC) and whether hypogonadism and frailty are associated with adverse postoperative outcomes. MATERIALS AND METHODS: The IBM MarketScan database was used to identify men who underwent RC between 2012 and 2021. Frailty was determined using published Hospital Frailty Risk Score ranges. Patients were considered to have hypogonadism if diagnosed within 5 years prior to RC. Length of stay (LOS), complications, emergency department (ED) visits and inpatient readmissions were compared. Sub-group analysis of men with hypogonadism was performed to determine the effect of testosterone replacement therapy (TRT) on clinical outcomes. RESULTS: Among 3,727 men who underwent RC, 226 (6.1%) had a diagnosis of hypogonadism. Overall, 565 (15.2%) men were low-risk frailty, 2,214 (59.4%) intermediate-risk frailty, and 948 (25.4%) were high-risk frailty, and men with hypogonadism were significantly more frail compared to men without hypogonadism (P = 0.027). There was no significant difference in LOS, complications, or rate of ED visits and inpatient readmissions between cohorts (P > 0.05). However, high-risk frailty was associated with an increased risk of 90-day ED visit (HR 1.19, 95%CI 1.00-1.41, P = 0.049) and 90-day readmission (HR 1.60, 95%CI 1.29-1.97, P < 0.001) after RC. Among men with hypogonadism, 58 (25.7%) were on TRT. There was no significant difference in frailty, LOS, complications, or 90-day ED visits or 90-day inpatient readmissions between patient with hypogonadism prescribed TRT and those without TRT. CONCLUSIONS: These findings suggest that hypogonadism and preoperative frailty may be important to evaluate prior to undergoing RC.

Prevalence of sexual dysfunction and pursuit of sexual medicine evaluation among male physicians-a survey.

We sought to characterize the prevalence of sexual dysfunction and barriers to treatment among male physicians. Between June and December 2022, male physicians were invited to complete a questionnaire regarding sexual function. Surveys were disseminated electronically via social media and professional medical societies using Qualtrics (Provo, UT). In totla, 235 responses were included in the final analysis. The mean age of respondents was 36.3 ± 7.4 years (range 23-72). 27 (11.5%) reported having seen a doctor for sexual health. Of these 27, 40.7% saw a physician for erectile dysfunction, 29.6% for low libido, 22.2% for premature ejaculation, 7.4% for delayed ejaculation, and 33.3% for other concerns. An additional 29 (12.3%) considered establishing care for sexual issues but didn't, mostly due to being too busy. 46 (19.6%) respondents reported having taken medication to improve erectile function. Therefore, in a cohort of young male physicians, 23.8% had seen or considered seeing a doctor for sexual health concerns, and nearly 1 in 5 had taken medication for erectile dysfunction. Male physicians appear to be at higher risk for sexual dysfunction than the general population and face significant and unique barriers in access to care for sexual dysfunction.

Predictors of Semen Parameters Decline Following the Microsurgical Varicocelectomy.

Objective Varicocele is considered the most common reversible cause of male infertility. However, some men do not clinically improve after surgical repair. We aimed to identify preoperative factors associated with decreased semen parameters and clinical "downgrading" of total motile sperm count (TMSC) following varicocelectomy. Methods We examined men with preoperative laboratory testing and pre- and postoperative semen analyses (SA) who underwent varicocelectomy between 2010 and 2020. Ejaculate volume, sperm motility, sperm concentration, TMSC, and clinical grade of TMSC (in vitro fertilization: <5M sperm, intrauterine insemination: 5-9M sperm, natural pregnancy: >9M sperm) were used to determine postoperative outcomes. Demographic and clinical factors were compared between cohorts. Results Among 101 men who underwent varicocelectomy, 35 (34.7%) had decreased postoperative TMSC with a median follow-up of 6.6 months (interquartile range 3.9-13.6 months). Eleven (10.9%) men experienced TMSC clinical "downgrading" following surgery. Clinical grade III varicocele was significantly associated with decreased sperm motility on postoperative SA (OR 4.1, 95% CI 1.7-10.0, p=0.002), and larger left testicle volume (OR 1.4, 95% CI 1.1-1.8, p=0.02) was associated with clinical "downgrading" after varicocelectomy. Conclusion A small but significant proportion of men experienced a "downgrading" of semen parameters after varicocelectomy. Larger left testis size was associated with clinical downgrading, whereas clinical grade III varicoceles were associated with lower post-treatment sperm motility. These data are critical for preoperative patient counseling.

Factors associated with undergoing microdissection testicular sperm extraction among men with non-obstructive azoospermia following evaluation by a reproductive urologist.

Background: Microdissection testicular sperm extraction (mTESE) is the gold standard treatment for men with non-obstructive azoospermia (NOA). However, many men do not elect to pursue this surgical intervention. We aimed to identify factors associated with NOA patients undergoing mTESE after initial evaluation by a reproductive urologist (RU) through a retrospective cohort study. Methods: We retrospectively reviewed NOA patient who underwent evaluation by a RU between 2002-2018. Demographic and clinical data were collected. Our primary outcome was electing to undergo mTESE. Results: 44.4% (75/169) of NOA men underwent mTESE. These patients earned significantly higher median neighborhood income ($133,000 vs. $97,000, P<0.001), spent fewer years trying to conceive before seeking care {1.3 [interquartile range (IQR): 1-3] vs. 2.3 (IQR: 1-5), P=0.012}, and were more likely to be married (79.7% vs. 53.9%, P=0.001). On univariate analysis, married men [odds ratio (OR) 3.37, 95% confidence interval (CI): 1.67-6.79, P=0.001] and men with higher neighborhood income (OR 1.14, 95% CI: 1.06-1.21, P<0.001) were more likely to undergo mTESE, while couples attempting to conceive for a longer period of time prior to initial evaluation were less likely to undergo mTESE (OR 0.79, 95% CI: 0.68-0.92, P=0.003). On multivariable regression analysis, marital status and years attempting to conceive remained significantly associated with NOA patients undergoing mTESE (OR 4.61, 95% CI: 1.16-18.25, P=0.03; OR 0.67, 95% CI: 0.52-0.88, P=0.003, respectively). Conclusions: Higher neighborhood income and marital status were positively associated with patients undergoing mTESE, while couples who attempted to conceive for a longer period of time before seeking infertility care were less likely to undergo mTESE.

Assessing the Prevalence of Low Testosterone and Elevated Follicle Stimulating Hormone Among Men Presenting for Fertility Evaluation Without Oligospermia.

OBJECTIVE: To compare the prevalence of abnormal hormone parameters among men with and without oligospermia to determine the value of universal hormonal screening during initial fertility evaluation. MATERIALS AND METHODS: We retrospectively evaluated men who underwent semen analysis and hormonal evaluation (morning testosterone [T] and follicle-stimulating hormone [FSH]) between January 2002 and May 2021. Sperm concentration was dichotomized at 15 million/mL according to World Health Organization (WHO) criteria. We compared median and interquartile range (IQR) T and FSH levels according to sperm concentration using Kruskal-Wallis test. Differences in prevalence of low testosterone (<300 ng/dL) and abnormal FSH (>7.6mIU/mL) were determined using chi-square test. RESULTS: 1164 men had a morning serum T. There was no difference in median T among men with normal vs abnormal sperm concentration (316 ng/dL, IQR 250-399 vs 316 ng/dL, IQR 253-419; P = .52). FSH was measured in 1261 men. Median FSH was higher among men with sperm concentration <15 million/mL (6.0IU/mL, IQR 3.9-10.7 vs 3.8IU/mL, IQR 2.7-5.7; P < .001). Among men with ≥15 million/mL concentration, 44.1% were found to have low T (P = .874) and 10.8% had an FSH ≥7.6 mIU/mL (P < .001). Among men with ≥15 million/mL sperm concentration who underwent both T and FSH evaluation, 43.6% had at least 1 hormonal abnormality. CONCLUSION: Almost half of men with normal sperm concentration had low T. As low T may have long-term implications for both fertility and overall health, providers should consider universal T screening in men presenting for fertility evaluation.

The Association between Monthly, Yearly, and Lifetime Cannabis Use, and Semen Parameters in Asian-American Men.

PURPOSE: Medicinal and recreational cannabis use has grown exponentially, however, its effect on testicular function and spermatogenesis remains uncertain. The aim of this study was to evaluate the association between cannabis use and semen parameters in a cohort of Asian-American men with unknown fertility. MATERIALS AND METHODS: Asian men were recruited to complete an online survey and submit a semen sample. Semen analysis, demographic data, lifestyle factors, and cannabis use habits were collected. Linear and logistic regression analyses were used to determine. RESULTS: Among the 112 men included in this study, 51 used cannabis at least once in their lifetime, 30 men used cannabis at least once in the last 12 months, and 26 men used cannabis at least once in the last 30 days. Adjusted linear regression analyses identified an association between cannabis use in the previous 30 days and worse sperm morphology (ß: -0.45, p=0.025) and sperm motility (ß: -1.64, p=0.016). However, when stratifying by subfertile semen quality (i.e., WHO criteria), no association was identified between semen quality and cannabis use. Lower sperm morphology and motility are partially associated with recent cannabis use, while all other semen parameters are not. CONCLUSIONS: We did not observe any consistent associations between cannabis use on any semen parameters in Asian-American men. Further studies within the field are needed to explore racial and ethnic differences in semen quality and lifestyle factors.

The broad reach and inaccuracy of men's health information on social media: analysis of TikTok and Instagram.

Social media (SoMe) offers great potential to expand access to health information, but a significant proportion of users consume its content instead of consulting a physician. We sought to quantify the volume and characterize the accuracy of men's health-related content on TikTok and Instagram. We searched TikTok and Instagram for the terms: testosterone, erectile dysfunction, male infertility, semen retention, Peyronie's disease, and vasectomy. The top 10 hashtags for each term were used to estimate the total impressions for each term on each platform, and posts were then characterized by creator type, content type, and accuracy (1 to 5 scale). TikTok had 2,312,407,100 impressions and Instagram had 3,107,300 posts across all topics. Semen retention had the most impressions on TikTok (1,216,074,000) and posts on Instagram (1,077,000). Physicians created only a small portion of total TikTok and Instagram posts (10.3% and 12.9%, respectively). Across all topics, the accuracy of content was poor (2.6 ± 1.7), however, physician posts were more accurate than non-physician posts (mean 4.2 ± 1.2 vs 2.3 ± 1.6, p < 0.001, respectively). Men's health content is popular on TikTok and Instagram but is not accurate. We recommend that physicians actively engage in SoMe to address misinformation.

ALDH2 Expression, Alcohol Intake and Semen Parameters among East Asian Men.

PURPOSE: Inactivating mutations in mitochondrial aldehyde dehydrogenase 2 (ALDH2) are highly prevalent. The most common variant allele, ALDH2*2, is present in 40%-50% of East Asians, and causes acetaldehyde accumulation, flushing and tachycardia after alcohol intake. The relationship between alcohol intake and ALDH2 genotype on semen parameters remains unknown. MATERIALS AND METHODS: We conducted a cross-sectional study to determine the association between ALDH2 genotype, alcohol consumption and semen parameters among East Asian men. Volunteers completed a survey and submitted a semen sample for analysis. Participants were genotyped to determine ALDH2 status (ALDH2*1/*1, ALDH2*1/*2, ALDH2*2/*2), and immunohistochemical staining was used to determine protein expression of ALDH2 in spermatozoa. RESULTS: Of 112 men 45 (40.2%) were ALDH2*2 carriers. Among ALDH2*2 carriers, alcohol consumption was associated with significantly lower total sperm motility (median 20% [interquartile range 11%-42%] vs 43% [IQR 31%-57%], p=0.005) and progressive sperm motility (19% [IQR 11%-37%] vs 36% [IQR 25%-53%], p=0.008). Among alcohol consumers, ALDH2*2 carriers had significantly lower total sperm motility (20% [IQR 11%--42%] vs 41% [IQR 19%-57%], p=0.02), progressive sperm motility (19% [IQR 11%-37%] vs 37% [IQR 17%-50%], p=0.02) and total motile sperm count (28 million [M; IQR 9-79M] vs 71M [IQR 23-150M], p=0.05) compared to ALDH2*1/*1 individuals. Secondly, ALDH2 expression in human spermatozoa was significantly lower in ALDH2*2 carriers (ALDH2*1/*1 vs ALDH2*1/*2, p=0.01; ALDH2*1/*1 vs ALDH2*2/*2, p <0.001). CONCLUSIONS: Our findings suggest genotyping ALDH2, coupled with alcohol cessation counseling, may improve semen parameters among men.

Primary malignancies of the epididymis: clinical characteristics and prognostic factors.

INTRODUCTION We sought to describe clinical characteristics and identify prognostic factors among patients with primary malignancies of the epididymis (PMEs). MATERIALS AND METHODS: The Surveillance, Epidemiology, and End Results (SEER) database (1975-2015) was queried to identify patients with PME. Descriptive statistics and multivariable Cox proportional hazards models were used. RESULTS: Eighty-nine patients with PME were identified. Median age was 57 years (5-85), and median overall survival (OS) was 16.8 years. The most commonly represented histologies were rhabdomyosarcoma (19.1%), B-cell lymphoma (16.9%), leiomyosarcoma (16.9%), and liposarcoma (12.4%). In multivariable analysis, tumor size ≥ 4 cm was associated with worse OS (HR = 4.46, p = 0.01) compared to tumors < 4 cm. Patients with nonsarcomatoid histology had OS similar to patients with sarcomatoid histology (HR = 0.95, p = 0.92). Disease with regional invasion (HR = 5.19, p = 0.007) and distant metastasis (HR = 29.80, p = 0.0002) had worse OS compared to localized disease. Receipt of radiotherapy was associated with enhanced OS (HR = 0.10, p = 0.006), whereas receipt of chemotherapy was not associated with OS. CONCLUSIONS: We describe the largest cohort of PMEs to date. Larger lesions and tumor stage were independently associated with poor overall survival, while receipt of radiotherapy was associated with enhanced overall survival.

Racial and socioeconomic disparities in retroperitoneal lymph node dissection and survival in nonseminomatous germ cell tumor: A population-based study.

BACKGROUND: Though testicular cancer is the most common cancer in young men, there is a paucity of epidemiologic studies examining sociodemographic disparities in adjuvant therapy and outcomes. We examined the associations of sociodemographic factors with retroperitoneal lymph node dissection (RPLND) and survival among patients with nonseminomatous germ cell tumors (NSGCTs). METHODS: Within the Surveillance Epidemiology and End Results database (2005-2015), we identified 8,573 patients with nonseminomatous germ cell tumors. Multivariable logistic regression and Fine-Gray competing-risks regression models were constructed to examine the association of sociodemographic factors (neighborhood SES (nSES), race, and insurance) with, respectively, adjuvant RPLND within 1 year of diagnosis and cancer-specific mortality. RESULTS: Patients in the lowest nSES quintile (OR 0.59, 95% CI = 0.40-0.88, P = 0.01) and Black patients (OR 0.41, 95% CI = 0.15-1.00, P= 0.058) with stage II disease were less likely to receive RPLND compared to those in the highest quintile and White patients, respectively. Stage III patients with Medicaid (OR 0.64, 95% CI = 0.46-0.89, P= 0.009) or without insurance (OR 0.46, 95% CI = 0.27-0.76, P= 0.003) were less likely to receive RPLND compared to patients with private insurance. Lowest quintile nSES patients of all disease stages and Black patients with stage I disease (HR = 2.64, 95% CI = 1.12-6.20, P = 0.026) or stage II disease (HR=4.93, 95% CI = 1.48-16.44, P = 0.009) had higher risks of cancer-specific mortality compared to highest quintile nSES and White patients, respectively. CONCLUSIONS: This national study found multilevel, stage-specific sociodemographic disparities in receipt of RPLND and survival.

The quality of systematic reviews and meta-analyses assessing the treatment and management of male infertility.

BACKGROUND: Male factor infertility (MFI) is a common medical condition which requires high-quality research to guide clinical practice; however, systematic reviews (SRs) and meta-analyses (MAs) often vary in quality, raising concerns regarding the validity of their results. We sought to perform an objective analysis of SRs and MAs in MFI treatment and management and to report on the quality of published literature. METHODS: A comprehensive search in PubMed/MEDLINE and Embase was used to identify relevant publications. Primary search terms were male infertility, male sterility, and male subfertility. Two authors independently performed searches, screened citations for eligibility, extracted data for analysis, and graded methodological quality using the validated AMSTAR (A Measurement Tool to Assess Systematic Reviews) instrument, a validated tool used in the critical appraisal of SRs/MAs. RESULTS: Of 27 publications met inclusion criteria and were included in the analysis. Mean AMSTAR score (± SD) among all publications was 7.4 (1.9) out of 11, reflecting "fair to good" quality. Non-pharmacological medical treatment for MFI was the most commonly assessed intervention (n = 13, 48.1%). No publications met all AMSTAR criteria. While the number of SRs/MAs has increased over time (P = 0.037), the quality of publications has not significantly changed (P = 0.72). SRs/MAs of the Cochrane Library had higher AMSTAR score than non-Cochrane SRs/MAs (8.5 vs 6.3, P = 0.002). CONCLUSIONS: The methodological quality of SRs/MAs should be assessed to ensure high-quality evidence for clinical practice guidelines in MFI treatment and management. This review highlights a need for increased effort to publish high-quality studies in MFI treatment and management.

Development of robust artificial neural networks for prediction of 5-year survival in bladder cancer.

PURPOSE: When exploring survival outcomes for patients with bladder cancer, most studies rely on conventional statistical methods such as proportional hazards models. Given the successful application of machine learning to handle big data in many disciplines outside of medicine, we sought to determine if machine learning could be used to improve our ability to predict survival in bladder cancer patients. We compare the performance of artificial neural networks (ANN), a type of machine learning algorithm, with that of multivariable Cox proportional hazards (CPH) models in the prediction of 5-year disease-specific survival (DSS) and overall survival (OS) in patients with bladder cancer. SUBJECTS AND METHODS: The National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) 18 program database was queried to identify adult patients with bladder cancer diagnosed between 1995 and 2010, yielding 161,227 patients who met our inclusion criteria. ANNs were trained and tested on an 80/20 split of the dataset. Multivariable CPH models were developed in parallel. Variables used for prediction included age, sex, race, grade, SEER stage, tumor size, lymph node involvement, degree of extension, and surgery received. The primary outcomes were 5-year DSS and 5-year OS. Receiver operating characteristic curve analysis was conducted, and ANN models were tested for calibration. RESULTS: The area under the curve for the ANN models was 0.81 for the OS model and 0.80 for the DSS model. Area under the curve for the CPH models was 0.70 for OS and 0.81 for DSS. The ANN OS model achieved a calibration slope of 1.03 and a calibration intercept of -0.04, while the ANN DSS model achieved a calibration slope of 0.99 and a calibration intercept of -0.04. CONCLUSIONS: Machine learning algorithms can improve our ability to predict bladder cancer prognosis. Compared to CPH models, ANNs predicted OS more accurately and DSS with similar accuracy. Given the inherent limitations of administrative datasets, machine learning may allow for optimal interpretation of the complex data they contain.

Clinicopathologic features, outcomes, and prognostic factors of testicular sarcoma: a population-based study.

PURPOSE: To describe clinical characteristics and identify prognostic factors among men with testicular sarcoma, and to compare survival with other testicular cancers. METHODS: The surveillance, epidemiology, and end results (SEER) database (1975-2016) was queried to identify adults with testicular sarcoma. Multivariable Cox proportional hazards, Fine and Gray competing-risks regression, propensity score matching, and Kaplan-Meier analyses were used. RESULTS: 230 men were included in this study. Median age at diagnosis was 58 years (range 18-94), and median OS was 10.3 years. Patients with tumors larger than 8 cm in size had worse OS (HR 1.88, p = 0.016) compared to patients with tumors < 8 cm. Disease with distant metastasis was associated with worse OS (HR 4.70, p < 0.0001) and worse CSS (HR 11.41, p < 0.0001) as compared to disease localized to the testis. Men with rhabdomyosarcoma had worse CSS (HR 3.25, p = 0.03) as compared to men with liposarcoma. Testicular sarcoma patients had worse OS than matched patients with either seminomatous germ cell tumors (GCTs, p < 0.0001) or nonseminomatous GCTs (p = 0.0019), and similar survival to matched patients with sex cord stromal tumors, testicular lymphoma, or sarcomas of the lower limb-the most common anatomic site of origin of soft tissue sarcomas. CONCLUSIONS: In the largest cohort of men with testicular sarcoma to date, we identified tumor size, disease extent, and rhabdomyosarcoma histology as independent predictors of worse survival. Stage-adjusted survival was worse as compared to men with GCTs, and similar to men with sex cord stromal tumors, testicular lymphoma, and sarcomas of other primary sites.

A population-level analysis of nonsquamous penile cancer: The importance of histology.

BACKGROUND: Nonsquamous penile cancers comprise 5% of penile malignancies, though their clinicopathologic features and prognostic significance remain unknown. We used a national cancer registry to detail clinical characteristics and compare cancer-specific mortality (CSM) of nonsquamous cancers with squamous cell carcinoma (SCC). METHODS: The Surveillance, Epidemiology, and End Results (SEER) database (1975-2016) was queried to identify adults with nonsquamous penile cancer and penile SCC. Multivariable Fine and Gray competing-risks regression, propensity score matching, and cumulative incidence plots were used. RESULTS: 666 men with nonsquamous penile cancer and 5,894 men with penile SCC were identified. The most commonly represented nonsquamous histological subtypes were Kaposi sarcoma (n = 183, 27.5%), melanoma (n = 74, 11.1%), basal cell carcinoma (n = 65, 9.8%), and extramammary Paget disease (n = 42, 6.3%). Cumulative incidence plots revealed a 10-year CSM rate of 32.6% in the nonsquamous penile cancer group and 25.6% in the matched penile SCC group (P < 0.0001). Among Kaposi sarcoma patients and matched SCC patients, we found a 10-year CSM rate of 29.6% in the Kaposi sarcoma group and 15.3% in the penile SCC group (P = 0.002). Similarly, a comparison of penile melanoma patients with matched SCC patients revealed a 10-year CSM rate of 38.4% in the melanoma group and 16.6% in the SCC group (P = 0.002). There was no difference in CSM between patients with basal cell carcinoma and SCC. In a sensitivity analysis limiting year of diagnosis to 2000 and onward, we found no difference in CSM between the general nonsquamous cohort or the Kaposi sarcoma cohort and matched SCC patients, but contemporary melanoma patients maintained worse CSM with a 10-year rate of 38.4% vs. 15.8% in matched SCC patients (P = 0.045). CONCLUSIONS: The most common nonsquamous penile cancers are Kaposi sarcoma, melanoma, and basal cell carcinoma. Overall, CSM is higher in nonsquamous penile cancers as compared to stage-matched SCC. Outcomes are similar in modern patients, likely due to improved control of systemic HIV in patients with Kaposi sarcoma. However, men with penile melanoma continue to experience a higher rate of CSM.

Bupivacaine local anesthetic to decrease opioid requirements after radical cystectomy: Does formulation matter?

INTRODUCTION: Reduction of opioids is an important goal in the care of patients undergoing radical cystectomy (RC). Liposomal bupivacaine (LB) has been shown to be a safe and effective pain reliever in the immediate postoperative period and has been reported to reduce postoperative opioid requirements. Since the liposomal formulation is predicated on slow systemic absorption, the amount of bupivacaine administered is notably higher than that typically used with standard bupivacaine (SB) formulations. In addition, LB is costly, not universally available, and studies comparing this formulation to SB are lacking. We sought to determine if there is a difference in postoperative opioid requirements in patients who receive LB vs. high dose SB at the time of RC. METHODS: In May 2019 we transitioned to administration of high-volume SB injected intraoperatively at the time of RC. This prospective cohort was compared to a historical cohort of patients who received injection of LB at the time of surgery. Primary endpoints included postsurgical opioid use measured in morphine equivalent dose (MED) and patient-reported Numeric Rating Scale (NRS) pain scores and length of stay. All patients were managed using principles of enhanced recovery after surgery (ERAS). RESULTS: From May 2019 through August 2019, 28 patients underwent RC and met eligibility criteria to receive SB at the time of surgery. They were compared to a historical cohort of 34 patients who received LB between November 2017 and July 2018. There was no difference in MED exposure either in the postanesthesia care unit (SB 9.0 ± 8.9 MED vs. LB 6.5 ± 9.4 MED, P= 0.29) or during the remainder of the hospital stay (SB 36.8 ± 56.9 MED vs. LB 42.1 ± 102.5 MED, P= 0.81), no difference in NRS pain scores on postoperative day 1 (SB 2.6 ± 1.6 vs. LB 2.1 ± 1.7, P= 0.23), day 2 (SB 2.4 ± 1.8 vs. LB 1.9 ± 1.6, P= 0.19), or day 3 (SB 1.9 ± 1.8 vs. LB 1.7 ± 1.7, P= 0.69) and no difference in length of stay (SB 5.0 ± 1.7 days, LB 4.9 ± 3.3 days, P= 0.93). Subgroup analysis of open RC and robotic-assisted RC showed no significant difference in MED or pain scores between LB and SB patients. CONCLUSIONS: Among patients undergoing RC under ERAS protocol there was no significant difference in postoperative opioid consumption, NRS pain scores, or length of stay among patients receiving SB compared to LB.
