RESUMO

INTRODUCTION: Spina bifida (SB) occurs in 3.5/10,000 live births and is associated with significant long-term neurologic and urologic morbidity. We explored the characteristics and outcomes of pediatric patients with SB and the facilities that treat them in Texas. METHODS: We retrospectively reviewed a statewide hospital inpatient discharge database (2013-2021) to identify patients aged <18 y with SB using International Classification of Diseases 9/10 codes. Patients transferred to outside hospitals were excluded to avoid double-counting. Descriptive statistics and chi-square test were performed. RESULTS: Seven thousand five hundred thirty one inpatient hospitalizations with SB were analyzed. Most SB care is provided by a few facilities. Two facilities (1%) averaged >100 SB admissions per year (33% of patients), while 15 facilities (8%) treat 10-100 patients per year (51% of patients). Most facilities (145/193, 75%) average less than one patient per year. Infants tended to be sicker (17% extreme illness severity, P < 0.001). Overall mortality is low (1%), primarily occurring in the neonatal period (8%, P < 0.001). Most admissions are associated with surgical intervention, with 63% of encounters having operating room charges with an average cost of $25,786 ± 24,884. Admissions for spinal procedures were more common among infants, whereas admissions for genitourinary procedures were more common among older patients (P < 0.001). The average length of stay was 8 ± 16 d with infants having the longest length of stay (19 ± 33, P < 0.001). CONCLUSIONS: Patients have significant long-term health needs with evolving pediatric surgical indications as they grow. Pediatric SB care is primarily provided by a small number of facilities in Texas. Longitudinal care coordination of their multidisciplinary surgical care is needed to optimize patient care.

RESUMO

Prune belly syndrome (PBS), also known as Eagle-Barret syndrome, is a rare, multi-system congenital myopathy primarily affecting males. Phenotypically, PBS cases manifest three cardinal pathological features: urinary tract dilation with poorly contractile smooth muscle, wrinkled flaccid ventral abdominal wall with skeletal muscle deficiency, and intra-abdominal undescended testes. Genetically, PBS is poorly understood. After performing whole exome sequencing in PBS patients, we identify one compound heterozygous variant in the PIEZO1 gene. PIEZO1 is a cation-selective channel activated by various mechanical forces and widely expressed throughout the lower urinary tract. Here we conduct an extensive functional analysis of the PIEZO1 PBS variants that reveal loss-of-function characteristics in the pressure-induced normalized open probability (NPo) of the channel, while no change is observed in single-channel currents. Furthermore, Yoda1, a PIEZO1 activator, can rescue the NPo defect of the PBS mutant channels. Thus, PIEZO1 mutations may be causal for PBS and the in vitro cellular pathophysiological phenotype could be rescued by the small molecule, Yoda1. Activation of PIEZO1 might provide a promising means of treating PBS and other related bladder dysfunctional states.

RESUMO

LUMBAR syndrome is rare with a multitude of features that requires a high index of suspicion for timely diagnosis and appropriate management. We present on a newborn female whose untreated segmental infantile hemangioma lead to poor healing of her bladder exstrophy closure. The objective of this report is to describe bladder exstrophy as a urogenital anomaly in patients with LUMBAR syndrome and the importance of balancing management of infantile hemangioma and time to surgery.

RESUMO

Anterior abdominal wall defects are rare anomalies that can affect multiple organ systems including gastrointestinal, genitourinary, musculoskeletal, and the neurospinal axis. The highly varied, complex anatomy in this patient population creates a challenging reconstruction scenario that merits careful surgical planning. We present an unusual female variant with an anorectal malformation as well as musculoskeletal and genital abnormalities consistent with classic bladder exstrophy in which the urinary bladder, sphincter, and urethra were largely uninvolved.

RESUMO

INTRODUCTION: Acute priapism is usually considered a medical emergency that warrants prompt urologic evaluation and treatment. Efforts have been made to determine the optimal management strategy for pediatric priapism. OBJECTIVE: The aim of this study is to assess differences in conservative, minimally-invasive, and operative management of acute priapism in the pediatric population. STUDY DESIGN: A retrospective study of pediatric patients with acute priapism from 2015 to 2021 at a single tertiary care children's hospital was conducted. Conservative, minimally-invasive, and operative approaches for the priapism episodes during these hospital encounters were analyzed. RESULTS: Thirty-nine patients were identified with a total of 61 cases of acute pediatric priapism were evaluated in the study period. Eight-three percent of patients were African-Americans, and 72% of patients had a history of sickle cell disease. Oxygen therapy (P = 0.001) and hydration with intravenous fluids (P = 0.00318) were more commonly utilized for hematologic-associated cases compared to other etiologies. For priapism episodes of hematologic etiology, 18 (40.0%) and 18 (40.0%) patients received phenylephrine injection and aspiration/irrigation (e.g., minimally-invasive therapy), respectively, while for the other causes of priapism, three (18.8%) and four (25.0%) received phenylephrine injection and aspiration/irrigation (e.g., minimally-invasive), respectively. Conservative and minimally-invasive treatment resulted in complete resolution of priapism in 27 (60%) and 16 (35.5%) patients with hematologic-associated priapism while 12 (75%) and 1 (6.3%) patients with other etiologies had resolution of priapism with conservative and minimally-invasive treatment, respectively. One patient received shunting in the hematologic group while two patients received shunting in the non-hematologic group (P = 0.1031). DISCUSSION: Hematologic disorders are the most common causes of priapism in children and adolescents. An overwhelming majority of priapism events in the pediatric population can be managed with conservative therapies including oxygenation and intravenous hydration as well as minimally-invasive procedures such as corporal aspiration, irrigation and/or injections. The utilization of corporal shunting, anesthesia, and hospital resources is infrequently necessary for pediatric priapism episodes. CONCLUSION: While urgent surgical management is often performed in the adult population, a minimally-invasive management strategy can be implemented in the pediatric population where an extended period of conservative management that avoids operative management and general anesthesia is effective.

RESUMO

Bladder masses are an infrequent occurrence rarely suspected in cases of pediatric hematuria. Inflammatory myofibroblastic tumors represent one differential diagnosis that is difficult to characterize as purely benign and should therefore be given special consideration. Although uncommon, this is an important entity to recognize for potential bladder sparing and minimally invasive surgical approaches.

RESUMO

BACKGROUND: Patients with transverse myelitis (TM) often present with urinary retention. While many recover their bladder function, some have persistent voiding dysfunction, and both intermediate and long-term outcomes are variable. OBJECTIVE: In patients who develop urinary retention requiring clean intermittent catheterization (CIC) at onset of TM, we sought to assess factors associated with improved voiding function and the risk of requiring persistent CIC over time. STUDY DESIGN: We reviewed children evaluated at our institution for TM from April 1998 to October 2018. Patients were included if they required CIC at initial presentation of TM. Demographics, initial and follow up neurologic exams were evaluated for their association with a return to baseline volitional voiding after requiring catheterization upon diagnosis of TM, with or without medical therapy. RESULTS: Among the 78 patients who presented with TM during the study period, 43 patients required CIC, with median follow up of 2.7 years. When evaluating for demographic or sensorimotor features associated with improvement to baseline voiding function in patients who initially required CIC, preserved lower extremity reflexes at presentation was the only significant prognostic factor (p < 0.05). Additionally, having complete lower motor neurologic recovery was associated with volitional voiding (p < 0.05). Among the 43 patients who were initially catheterizing, 27/43 (62%) were volitionally voiding at median follow up of 7 months from initial presentation, while the remaining 16/43 remained on CIC for a median follow up of 3.6 years. The cumulative risk of remaining on CIC was 60%, 47%, and 42% at 1, 5, and 10 year follow up, respectively, though there was not a significant difference in the rate of bladder recovery if patients had preserved reflexes. DISCUSSION: In children with TM who initially developed urinary retention, intact reflexes at presentation were associated with urologic recovery. Additionally, complete neurologic recovery was associated with volitional voiding. While 62% were volitionally voiding at most recent follow-up, the cumulative incidence of dependence on CIC within the first year of diagnosis was 60%, with a relatively few patients regaining volitional voiding by 10 years of follow-up. CONCLUSION: Among those initially evaluated for urinary retention in the setting of transverse myelitis, intact lower extremity reflexes on physical exam was associated with improved voiding function at most recent follow-up. However, more than half the patients on CIC at initial presentation required CIC at one year of follow-up. Careful, long-term monitoring of voiding status in patients with TM is recommended, even with improvement of neurological status.

RESUMO

A term infant with prenatally noted ambiguous genitalia and nonpalpable gonads presented with life-threatening hyponatremia, hypertension, acidosis, and anuric renal failure requiring peritoneal dialysis at age 3 months.Sequencing confirmed 46, XY Denys-Drash syndrome (DDS) due to heterozygous Wilms tumor-1 exon 8 mutation encoding p.His445Arg. Renal US identified bilateral multifocal renal masses at age 8 months. Bilateral retroperitoneal nephrectomies found bilateral nephroblastomatosis without Wilms' tumor avoiding chemotherapy, followed by bilateral laparoscopic orchiopexies. We suggest monthly screening of 46, XY DSD cases for DDS by evaluating for proteinuria and electrolyte disarray starting at diagnosis of DSD to prevent acute life-threatening renal failure presentation.

RESUMO

INTRODUCTION: With limited pediatric renal trauma management literature, treatment pathways for children have been extrapolated from the adult population. A shift to non-operative management has led to higher renal preservation rates; however, characterization of endovascular intervention in the pediatric trauma population is lacking. OBJECTIVE: This study uses the National Trauma Data Bank (NTDB), to evaluate renal outcomes after use of renal artery angiography. We hypothesized that patients undergoing renal artery angiography for renal trauma are unlikely to require additional surgical interventions. STUDY DESIGN: All children ≤18 years old treated for traumatic renal injuries from 2012 to 2015 were identified by the Abbreviated Injury Scaled Score (AISS) codes in the NTDB. AISS codes were converted to American Association for Surgery of Trauma (AAST) grades. ICD-9 codes were used to identify patients that had renal artery angiography, and additional renal interventions such as nephrectomy, partial nephrectomy, percutaneous nephrostomy tube or ureteral stent placement. RESULTS: 536,379 pediatric trauma cases were in the NTDB from 2012 to 2015, with 4506 renal injury cases identified. A total of 88 patients had renal artery angiography (ICD-9 88.45). Only 10% (n = 9) of patients who received renal artery angiography underwent an additional urological intervention. Of those nine, two patients were excluded due to renal angiography taking place after nephrectomy was performed. The remaining seven patients had high grade laceration (AAST grade 4-5). Overall, two patients underwent post angiography nephrectomies, two patients had partial nephrectomies, one percutaneous nephrostomy tube was placed (prior to partial nephrectomy), one aspiration of a kidney (prior to ureteral stent placement), and three had ureteral stent placements. DISCUSSION: The limitations of this study include: the NTDB is a national dataset that is not population based, inclusion is limited to the first hospitalization, inaccuracies exist in encounter coding, and the database is lacking laterality of the renal injury. Based on nonspecific nature of ICD-9 coding for angioembolization, we are unable to discern the number of cases that subsequently had angioembolization after or at the time of angiography. CONCLUSION: Renal artery angiography in children remains a rare procedure, 88/4,506, in children with renal trauma. In pediatric trauma cases that undergo renal artery angiography additional procedures are more common with higher grade injuries. Further studies are needed to create pediatric specific trauma management algorithms.

RESUMO

In the last decade, management of congenital UPJ obstruction has become progressively observational despite the lack of precise predictors of outcome. While it is clear that many children will have resolution of their hydronephrosis and healthy kidneys, it is equally clear that there are those in whom renal functional development is at risk. Surgical intervention for the young infant, under 6 months, has become relatively infrequent, yet can be necessary and poses unique challenges. This review will address the clinical evaluation of UPJO in the very young infant and approaches to determining in whom surgical intervention may be preferable, as well as surgical considerations for the small infant. There are some clinical scenarios where the need for intervention is readily apparent, such as the solitary kidney or in child with infection. In others, a careful evaluation and discussion with the family must be undertaken to identify the most appropriate course of care. Further, while minimally invasive pyeloplasty has become commonly performed, it is often withheld from those under 6 months. This review will discuss the key elements of that practice and offer a perspective of where minimally invasive pyeloplasty is of value in the small infant. The modern pediatric urologist must be aware of the various possible clinical situations that may be present with UPJO and feel comfortable in their decision-making and surgical care. Simply delaying an intervention until a child is bigger may not always be the best approach.

RESUMO

Minimally invasive techniques have gained popularity in pediatric surgery. Among these, is the robotic approach for ureteral reimplantation in children with vesico-ureteral reflux. We describe main indications of this surgery, our surgical technique as well as trouble shooting of anatomical variants and the post-operative management. We also provide a description of other techniques described in the literature and a brief review of outcomes of published series.

RESUMO

Robotic-assisted simple prostatectomy (RASP) has emerged as a safe and effective treatment option for symptomatic patients with lower urinary tract symptoms related to significant benign prostatic enlargement (BPE) above 80 g. The recent release of the da Vinci SP robotic system (Intuitive, Sunnyvale, CA, USA) continues to advance the minimally invasive nature of robotic surgical technology. We now report our institution's initial experience performing RASP using the da Vinci SP robotic system. An IRB-approved, retrospective chart review was performed of all patients undergoing robotic-assisted simple prostatectomy using the da Vinci SP surgical system in the treatment of benign prostatic enlargement by a single surgeon from March to June 2019. Pre-operative, intraoperative, and post-operative data were collected for descriptive analysis. A total of 10 men, mean age of 69 ± 4 years, with mean prostate volume of 104 ± 11 g underwent surgery. The robotic cannula and a single assistant port were utilized in all cases. No cases required conversion to a multi-port robotic platform or open approach, nor required the placement of additional assistant ports. No intraoperative or immediate post-operative complications were noted. Mean estimated blood loss was 141 ± 98 mL and operative time was 172 ± 19 min. Mean catheter time was 1.9 ± 1.8 days. One patient reported transient de novo stress urinary incontinence. Single-port RASP is a safe and effective intervention for BPE. The smaller surgical footprint from the device appears to make earlier catheter removal possible. Comparative evaluation with multi-port RASP and other modalities is warranted.

RESUMO

OBJECTIVE: To design a novel system of scoring prune belly syndrome (PBS) phenotypic severity at any presenting age and apply it to a large pilot cohort. PATIENTS AND METHODS: From 2000 to 2017, patients with PBS were recruited to our prospective PBS study and medical records were cross-sectionally analysed, generating individualised RUBACE scores. We designed the pragmatic RUBACE-scoring system based on six sub-scores (R: renal, U: ureter, B: bladder/outlet, A: abdominal wall, C: cryptorchidism, E: extra-genitourinary, generating the acronym RUBACE), yielding a potential summed score of 0-31. The 'E' score was used to segregate syndromic PBS and PBS-plus variants. The cohort was scored per classic Woodard criteria and RUBACE scores compared to Woodard category. RESULTS: In all, 48 males and two females had a mean (range) RUBACE score of 13.8 (8-25) at a mean age of 7.3 years. Segregated by phenotypic categories, there were 39 isolated PBS (76%), six syndromic PBS (12%) and five PBS-plus (10%) cases. The mean RUBACE scores for Woodard categories 1, 2, and 3 were 20.5 (eight patients), 13.8 (25), and 10.6 (17), respectively (P < 0.001). CONCLUSIONS: RUBACE is a practical, organ/system level, phenotyping tool designed to grade PBS severity and categorise patients into isolated PBS, syndromic PBS, and PBS-plus groups. This standardised system will facilitate genotype-phenotype correlations and future prospective multicentre studies assessing medical and surgical treatment outcomes.

RESUMO

OBJECTIVES: To determine the implications of different prostate sampling schemes on the diagnosis of clinically significant prostate cancer (csPCA, ISUP group 2-5) and clinically insignificant prostate cancer (ciPCA, ISUP group 1) in men with abnormal multiparametric magnetic resonance imaging (mpMRI) undergoing MRI-transrectal ulrasound fusion targeted biopsies. MATERIALS AND METHODS: This is a retrospective analysis of a cohort including all men who had a single lesion on mpMRI of the prostate performed between January 2016 and June 2017. All men underwent an MRI-transrectal ulrasound fusion biopsy and systematic (SBx) sampling of the prostate, which combined and were considered the standard of reference. The hypothetical 3 biopsy sampling schemes were defined as follows: Targeted biopsy only (TBx), TBx + ipsilateral SBx (ipsi-SBx) and TBx + contralateral SBx (contra-SBx) and were evaluated for the detection of csPCA and ciPCA. Sensitivity and 95% intervals were calculated, McNemar test was used to compare sensitivities between the various sampling schemes. RESULTS: TBx + SBx detected csPCa in 47% (55 of 116) of the 116 men who met eligibility criteria. Sensitivity and 95% confidence intervals for csPCa detection was 85.5% (73.3%-93.5%), 96.4% (87.5%-99.6%), and 92.7 (82.4%-98%) for TBx alone, TBx + ipsi-SBx and TBx + contra-SBx, respectively. csPCa detection rates were higher for both TBx + ipsi-SBx and TBx + contra-SBx compared to TBx alone. Clinically insignificant cancers alone were detected in 7.7% (9 of 116), 10.3% (12 of 116), and 14.6% (17 of 116) of the cohort by TBx only and TBx + ipsi-SBx, and TBx + contra-SBx, respectively. CONCLUSIONS: TBx + ipsi-SBx may increase the detection of csPCa while limiting overdiagnosis of indolent cancers.

RESUMO

OBJECTIVE: The purpose of this study was to assess the diagnostic performance of prospectively assigned mean apparent diffusion coefficient (ADC) values in multiparametric MRI (mpMRI) structured reports for discriminating clinically insignificant (International Society of Urological Pathology [ISUP] group 1) from clinically significant (ISUP groups 2-5) prostate cancer. MATERIALS AND METHODS: This single-center study included men with abnormal 3-T mpMRI findings (Prostate Imaging Reporting and Data System version 2 score, ≥ 3) who subsequently underwent radical prostatectomy or targeted biopsy with positive results. One of nine radiologists prospectively reported the mean ADC for each lesion during clinical interpretation. Lesions with ADC ≤ 0.700 mm2/s × 10-3 were flagged as concerning for clinically significant prostate cancer. The index lesion at MRI correlated with the site-concordant lesion at targeted biopsy or whole-mount histopathologic analysis. Logistic regression was used to evaluate the utility of mean ADC values for discriminating ISUP grade group 1 from groups 2-5. Diagnostic performance was assessed by ROC AUC. RESULTS: Among the 218 eligible men, those with ISUP group 2-5 lesions had lower mean ADC values than those with ISUP 1 lesions; overall, 0.598 vs 0.803 mm/s2 × 10-3 (p < 0.0001); peripheral zone (PZ), 0.597 vs 0.855 mm/s2 × 10-3 (p < 0.0001); transition zone (TZ), 0.600 vs 0.660 mm/s2 × 10-3 (p = 0.035). The AUC for the PZ was 0.91 and for the TZ was 0.70. The optimal ADC cutoff values were 0.682 mm/s2 × 10-3 for PZ lesions and 0.638 mm2/s × 10-3 for TZ lesions, resulting in sensitivity and specificity of 78% and 94% for the PZ and 72% and 67% for the TZ. CONCLUSION: ADC values estimated prospectively in a clinical setting can help differentiate clinically insignificant from clinically significant prostate cancer, facilitating prebiopsy and pretreatment risk stratification.

RESUMO

OBJECTIVE: The purpose of this study is to determine the reproducibility and diagnostic performance of a Likert scale in comparison with the European Society of Urogenital Radiology (ESUR) criteria and tumor-pseudocapsule contact length (TCL) for the detection of extraprostatic extension (EPE) at multiparametric MRI. MATERIALS AND METHODS: This was a retrospective review of all men who underwent multiparametric MRI followed by prostatectomy between November 2015 and July 2016. Multiparametric 3-T MRI studies with an endorectal coil were independently reviewed by five readers who assigned the likelihood of EPE using a 1-5 Likert score, ESUR criteria, and TCL (> 10 mm). EPE outcome (absent or present) for the index lesion at whole-mount histopathologic analysis was the standard of reference. Odds ratios (ORs) and areas under the ROC curve (Az) were used for diagnostic accuracy. The interreader agreement was determined using a weighted kappa coefficient. A p < 0.05 was considered significant. RESULTS: Eighty men met the eligibility criteria. At univariate analysis, the Likert score showed the strongest association (OR, 1.8) with EPE, followed by prostate-specific antigen level (OR, 1.7), ESUR score (OR, 1.6), and index lesion size (OR, 1.2). At multivariable analysis, higher Likert score (OR, 1.8) and prostate-specific antigen level (OR, 1.6-1.7) were independent predictors of EPE. The Az value for Likert scores was statistically significantly higher (0.79) than that for TCL (0.74; p < 0.01), but not statistically significantly higher than the value for ESUR scores (0.77; p = 0.17). Interreader agreement with Likert (κ = 0.52) and ESUR scores (κ = 0.55) was moderate and slightly superior to that for TCL (κ = 0.43). Except for TCL among inexperienced readers (κ = 0.34), reader experience did not affect interreader agreement. CONCLUSION: A Likert score conveying the degree of suspicion at multiparametric MRI is a stronger predictor of EPE than is either ESUR score or TCL and may facilitate informed decision making, patient counseling, and treatment planning.

RESUMO

OBJECTIVES: To evaluate the usage of surgical staging of inguinal lymph nodes (SSILNs) in the United States for intermediate to high-risk, clinically localized penile squamous cell cancer (SCC), to explore patient and hospital factors associated with omission of this staging, and to evaluate the effect on survival. PATIENTS AND METHODS: Retrospective, observational study using the National Cancer Database from 2004 to 2014 of 1,689 men diagnosed with pT1b-T3, cN0 penile SCC, who by current guidelines should receive SSILNs-either by inguinal lymph node (ILN) dissection or sentinel node biopsy. Binomial logistic regression analysis was performed to determine predictors of SSILNs. Multivariate Cox regression analysis was performed to determine the impact of SSILNs on survival in the overall and propensity-score matched patient populations. RESULTS: Only 25.3% of patients underwent SSILNs. Increasing patient age, higher comorbidity status, lower pathologic stage, Medicaid insurance, and treatment at a nonacademic facility were independent factors associated with the omission of SSILNs. Omission of SSILNs was an independent predictor of overall mortality, both in the overall patient population after multivariate adjustment, HR = 1.46 [(95% CI: 1.14-1.88), P = 0.003], and in the propensity-score matched adjusted population, HR = 1.59 [(95% CI: 1.20-2.13), P = 0.001]. Limitations include an inability to distinguish biopsy from ILN dissection and those inherent in observational study design. CONCLUSION: Utilization of SSILN for penile SCC is low and has not changed significantly since the publication of guidelines in the United States. In particular, nonacademic institutions were less likely to adhere to recommendations for performance of SSILNs. We found the omission of SSILNs is associated with a significant increase in mortality.

RESUMO

BACKGROUND: Optimal management of patients with lymph node metastasis (LNM) after radical prostatectomy (RP) remains undefined. OBJECTIVE: We evaluated the association between three different management strategies and survival in prostate cancer with LNM after RP. DESIGN, SETTING, AND PARTICIPANTS: We analyzed data of 1338 patients with LNM after RP from three tertiary care centers. Three hundred and eighty-seven patients (28%) were observed, 676 (49%) received lifelong adjuvant androgen deprivation therapy (ADT), and 325 (23%) received adjuvant external beam radiation therapy (EBRT) and ADT. Three hundred and sixty-eight men were followed for more than 10 yr. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Primary outcome measure was overall survival (OS). Secondary outcomes were cancer-specific survival (CSS) and other-cause mortality. Kaplan-Meier methods were used to visualize OS for the three treatment groups. Cox proportional hazards regression was utilized to compare OS and CSS among the three groups. RESULTS AND LIMITATIONS: ADT+EBRT was associated with better OS than ADT alone (hazard ratio [HR]: 0.46, 95% confidence interval [CI]: 0.32-0.66, p<0.0001) or observation (HR: 0.41, 95% CI: 0.27-0.64, p<0.0001). Higher-risk patients benefited more from ADT+EBRT than lower-risk patients. Ten-year mortality risk difference between ADT+EBRT, observation, or ADT alone ranged from 5% in low-risk patients to 40% in high-risk patients. Adjuvant ADT+EBRT was also associated with better CSS than observation or ADT alone (p<0.0001), ADT had better CSS compared to observation (HR: 0.64, 95% CI: 0.43-0.95, p=0.027). However, ADT was associated with an increased risk of other-cause mortality (HR: 3.05, 95% CI: 1.45-6.40, p=0.003) compared with observation, resulting in similar OS between ADT and observation (HR: 0.90, 95% CI: 0.65-1.25, p=0.5). While selection bias might remain, its effect would operate in the opposite direction to our findings. CONCLUSIONS: In men with LNM after RP, ADT+EBRT improved survival over either observation or adjuvant ADT alone. This survival benefit increases with higher-risk disease. PATIENT SUMMARY: Lymph node metastasis following radical prostatectomy is associated with poor survival outcomes. However, we found that adjuvant androgen deprivation therapy with external beam radiation therapy improved survival in these patients.

RESUMO

OBJECTIVE: To describe epidemiologic patterns, stage at presentation, histology, and treatment differences associated with Hispanic men diagnosed with testicular germ cell tumor (TGCT). Hispanics are the fastest growing demographic in the United States and reports suggest that the incidence of TGCT is rising most rapidly in this demographic, yet little is known about TGCTs in Hispanic patients. MATERIALS AND METHODS: We compared patient factors, tumor characteristics, treatment patterns, and outcomes of non-Hispanic white (NHW) vs Hispanic patients at our own institution in North Texas from 2010 to 2016. The findings were corroborated by analyzing the National Cancer Database testicular cancer registry from 2004 to 2014. RESULTS: We identified 154 patients with TGCT at our institution, of which 89 were NHW (56.0%) and 65 were Hispanic (40.9%). A review of the National Cancer Database identified 49,607 NHW patients (81.5%) and 6724 Hispanic patients (11.0%) diagnosed with TGCT. At presentation, Hispanic patients were approximately 5 years younger than NHW patients, delay seeking care for testicular cancer, were more likely to have nonseminomatous histology, had a larger tumor size, and had a higher disease burden at presentation. Additionally, we identified differences in treatment patterns at the national level. CONCLUSION: Differences in outcomes and treatment patterns of Hispanic and NHW patients with TGCT may represent underlying socioeconomic issues and access to care; however, discrepancies in age of onset and histology of TGCT between Hispanic and NHW patients may signify differences in tumor biology or risk factors. We suggest that this possibility be explored further as we embark upon the genomic classification of TGCT.
