Comparison of outcomes of radical and partial nephrectomy for sarcomatoid renal cell carcinoma: analysis of the national cancer database.

PURPOSE: To compare outcomes of radical (RN) and partial nephrectomy (PN) in Sarcomatoid Renal Cell Carcinoma (sRCC) utilizing a large national cohort. As RN is the reference standard for localized RCC with clinically aggressive features, PN in sRCC has been seldom studied. METHODS: We performed a retrospective cohort analysis of the National Cancer Database from 2004 to 2019 for patients who underwent PN and RN for sRCC (T1-T3N0-N1M0). We performed multivariable analyses (MVA) to determine factors associated with PN and all-cause mortality (ACM), and Kaplan-Meier Analysis (KMA) for overall survival (OS) in Charlson 0 patients who underwent PN vs. RN according to clinical stage. RESULTS: The cohort consisted of 5,265 patients [RN 4,582 (87.0%)/PN 683 (13.0%)]. Increased odds of receiving PN was associated with papillary RCC (OR = 1.69, p = 0.015); inversely with increasing age (OR = 0.99, p = 0.004), cT2-cT3 (OR = 0.23, p < 0.001), and cN1 (OR = 0.2, p < 0.001). Worsened ACM was associated with positive margins (HR = 1.59, p < 0.001), male (HR = 1.1, p = 0.044), Charlson [Formula: see text]2 (HR = 1.47, p < 0.001), cT2-cT3 (HR 1.17-1.39, p < 0.001-0.035), and cN1 (HR = 1.59, p < 0.001). Improved ACM was noted with PN (HR = 0.64, p < 0.001), increasing household income (HR = 0.77-0.79, p < 0.001), and private insurance (HR = 0.80, p = 0.018). KMA showed PN had improved 5-year OS compared to RN in cT1 (86.5% vs. 63.2%, p < 0.001), and cT3 (61.0% vs. 44.0% p < 0.001), but not cT2 (p = 0.67). CONCLUSION: In select patients, PN with negative margins may not compromise outcomes and may provide benefit when indicated. Patients with private insurance and highest income experienced improved survival suggesting disparity in care.

Oncological and Survival Outcomes of Pelvic Lymph Node Dissection in Patients with Nonmuscle Invasive Bladder Cancer Undergoing Radical Cystectomy Using the National Cancer Database.

OBJECTIVE: To evaluate the role of pelvic lymph node dissection (PLND) in patients diagnosed with high-risk nonmuscle-invasive bladder cancer (NMIBC) undergoing radical cystectomy (RC) using a national cohort of NMIBC patients. METHODS: A cohort of patients diagnosed with NMIBC cancer with urothelial carcinoma from the National Cancer Database (NCDB) between 2004 and 2019 was utilized. The cohort consists of patients who have not received BCG and underwent upfront radical cystectomy or pelvic exenteration. Kaplan-Meier analysis was utilized to assess overall survival (OS) outcomes. Cox regression was also utilized to identify independent predictors of OS. RESULTS: The cohort of 9399 patients was stratified by clinical T stage and then subdivided by pathological outcome. For patients with cTa, a majority received a lymph node dissection 97.74% (941/1019), amongst the entire cohort, a minority had node positive disease 3.3% (34/1019). For cTis, most patients received a lymph node dissection 94.08% (482/507), and a minority had node positive disease 5.1% (26/507). For cT1, most patients had a lymph node dissection 95.62% (6,060/6,337), and a 13.1% (832/6337) of patients had a positive lymph node. Amongst patients with cT1 disease who underwent PLND, KMA demonstrated better OS compared to patients who did not undergo PLND (P < .001). CONCLUSION: The data suggests an OS benefit in patients with later stage (cT1) NMIBC. Thus, our findings support the existing clinical guidelines of pelvic lymph node dissection in patients with high-risk nonmuscle invasive bladder cancer.

Incidence of Erectile Dysfunction and Testosterone Deficiency in Testicular Cancer Survivors.

PURPOSE: This project aims to characterize the incidence of men's health disorders, specifically focusing on the incidence of erectile dysfunction (ED) and testosterone deficiency (TD) in a large, nationwide study of Testicular cancer (TC) survivors treated in a centralized healthcare system. PATIENTS AND METHODS: We conducted a retrospective cohort study of US Veterans diagnosed with TC from 1990 to 2021. These were compared to an age and race-matched control group of US Veterans without a diagnosis of TC. ED and TD were defined by the presence of diagnosis codes or at least a 6-months prescription for medications treating these conditions or both. Time was measured from date of TC diagnosis (for TC patients, and matched TC patient date for the corresponding non-cancer controls). Impact of chemotherapy among TC survivors on ED and TD was evaluated using multivariable Cox regression models. RESULTS: The cohort included 1754 patients with TC compared to 7117 non-cancer controls, with a mean age at diagnosis of 42 years. TC patients were significantly more likely than controls to experience ED (hazard ratio 2.97, 95% CI 2.68 to 3.28, P < .001) and TD (hazard ratio 6.71, 95% CI 5.78-7.81, P < .001). However, within the TC group, there was no significant difference in the incidence of ED and TD when stratified by receipt of chemotherapy (P = .9 and P = .066, respectively). CONCLUSIONS: Men's health disorders arise commonly in the lives of TC survivors. It is important for treating physicians to identify these and conduct sexual health assessments as part of survivorship care.

Classification and Risk Factors for Surgical Site Infections in Radical Cystectomy: A 16-Year Analysis.

Introduction: Surgical site infection (SSI) is a substantial cause of peri-operative morbidity among patients undergoing radical cystectomy (RC). The purpose of this study was to identify the risk factors of SSI after RC and to classify and characterize treatment of SSIs. Methods: We retrospectively analyzed peri-operative characteristics and SSI, for patients undergoing RC from 2007 to 2022. Patients were stratified by SSI versus no SSI and differences were assessed. Uni-variable/multi-variable logistic regression analyses were performed to identify factors associated with SSI. SSIs were categorized by the Centers for Disease Control and Prevention (CDC) type: Superficial incisional, deep incisional, and organ/space confined. Results: Three hundred and ninety-eight patients had RC, 279 open, and 119 robotic; 78 (19.6%) developed SSI. Cohorts were similar demographically. Length of stay (LOS) was longer in the SSI cohort (8.8 d versus 12.4 d, p < 0.001), and body mass index (BMI) was greater in patients with SSI (24.34 vs. 25.39, p = 0.0003). On uni-variable analysis, age, gender, Charlson Comorbidity Index, diabetes mellitus, diversion, odds ratio (OR) time, blood loss, and open versus robotic technique were not substantial SSI predictors. BMI was an independent risk factor for SSI on both uni-variable (OR: 1.07, 95% confidence interval [CI]: 1.018-1.115, p = 0.0061) and multi-variable analysis (OR: 1.06, 95% CI: 1.009-1.109, p = 0.02) for 10 (12.8%) and 24 (30.8%) superficial and deep-incisional SSIs, respectively. Superficial wound SSI was treated conservatively with 60% receiving antibiotic agents and no procedural intervention. Deep SSIs received antibiotic agents and 50% required surgical intervention. There were 44 (56.4%) organ/space SSIs, and the most common treatment was antibiotic agents (100%) and IR drain placement (30, 68.2%). Conclusion: In patients undergoing RC, BMI was an independent risk factor for SSI. Type of the surgical procedure, robotic versus open, was not predictive of SSI. LOS was longer for patients with SSI. SSI was managed differently depending on CDC classification.

Comparison of Capture Rates of the National Cancer Database Across Race and Ethnicity.

Importance: The National Cancer Database (NCDB) is an invaluable and widely used resource for cancer research, but the current state of representation of different racial and ethnic groups compared with the United States Cancer Statistics (USCS) database is unknown. Objective: To examine whether Hispanic and American Indian or Alaska Native individuals have lower representation in the NCDB compared with the USCS database. Design, Setting, and Participants: This multicenter, retrospective cohort study assessed individuals diagnosed with breast, colorectal, lung, and prostate cancer from January 1, 2004, to December 31, 2006, and January 1, 2017, to December 31, 2019, in the NCDB and USCS databases. Data analysis was performed from September 2022 to October 2023. Exposure: Time. Main Outcomes and Measures: The primary outcome was the absolute percentage change (APC) in capture rate across the study period. Results: The cohort included 5 175 007 individuals (0.50% American Indian or Alaska Native, 3.10% Asian or Pacific Islander, 12.01% Black, 6.58% Hispanic, and 77.81% White) who were diagnosed with breast, colorectal, lung, and prostate cancer. Capture rates were the lowest for individuals who were Hispanic (40.83% in 2004-2006 and 54.75% in 2017-2019; P < .001) or American Indian or Alaska Native (20.72% in 2004-2006 and 41.41% in 2017-2019; P < .001). The APCs were positive for both racial categories across all 4 cancers. However, overall APCs for Hispanic individuals (13.92%) remained lower than the overall APCs of White individuals (22.23%; P < .001). The APCs were greater for American Indian or Alaska Native individuals than for White individuals for prostate (14.68% vs 11.57%) and breast (21.61% vs 17.90%) cancer (P < .001), but the APCs for American Indian or Alaska Native individuals were lower than for White individuals for lung cancer (24.54% vs 33.03%; P < .001). Conclusions and Relevance: In this cohort study of individuals diagnosed with cancer in the NCDB, Hispanic and American Indian or Alaska Native individuals diagnosed with breast, colorectal, lung, and prostate cancer were undercaptured in the NCDB, but their representation improved over time. Increased study is needed to determine where these populations predominantly seek cancer care.

A case of unprovoked segmental proximal partial thrombosis of the corpus cavernosum.

Partial thrombosis of the corpus cavernosum is an extremely rare and likely underdiagnosed urologic condition. We discuss a case of a 25-year-old male who presented with severe perineal pain and was diagnosed with idiopathic proximal partial thrombosis of the corpus cavernosum via ultrasound and MRI. The patient experienced symptom resolution with evidence of disease regression on follow up MRI after treatment with direct oral anticoagulation. Further studies are needed to fully delineate the pathophysiology of this condition to facilitate development of standardized diagnostic and treatment algorithms.

Low-Value Prostate-Specific Antigen Screening in Older Males.

Importance: The US Preventive Services Task Force guidelines advise against prostate-specific antigen (PSA) screening for prostate cancer in males older than 69 years due to the risk of false-positive results and overdiagnosis of indolent disease. However, this low-value PSA screening in males aged 70 years or older remains common. Objective: To characterize the factors associated with low-value PSA screening in males 70 years or older. Design, Setting, and Participants: This survey study used data from the 2020 Behavioral Risk Factor Surveillance System (BRFSS), a nationwide annual survey conducted by the Centers for Disease Control and Prevention that collects information via telephone from more than 400 000 US adults on behavioral risk factors, chronic illnesses, and use of preventive services. The final cohort comprised male respondents to the 2020 BRFSS survey who were categorized into the following age groups: 70 to 74 years, 75 to 79 years, or 80 years or older. Males with a former or current prostate cancer diagnosis were excluded. Main Outcomes and Measures: The outcomes were recent PSA screening rates and factors associated with low-value PSA screening. Recent screening was defined as PSA testing within the past 2 years. Weighted multivariable logistic regressions and 2-sided significance tests were used to characterize factors associated with recent screening. Results: The cohort included 32 306 males. Most of these males (87.6%) were White individuals, whereas 1.1% were American Indian, 1.2% were Asian, 4.3% were Black, and 3.4% were Hispanic individuals. Within this cohort, 42.8% of respondents were aged 70 to 74 years, 28.4% were aged 75 to 79 years, and 28.9% were 80 years or older. The recent PSA screening rates were 55.3% for males in the 70-to-74-year age group, 52.1% in the 75-to-79-year age group, and 39.4% in the 80-year-or-older group. Among all racial groups, non-Hispanic White males had the highest screening rate (50.7%), and non-Hispanic American Indian males had the lowest screening rate (32.0%). Screening increased with higher educational level and annual income. Married respondents were screened more than unmarried males. In a multivariable regression model, discussing PSA testing advantages with a clinician (odds ratio [OR], 9.09; 95% CI, 7.60-11.40; P < .001) was associated with increased recent screening, whereas discussing PSA testing disadvantages had no association with screening (OR, 0.95; 95% CI, 0.77-1.17; P = .60). Other factors associated with a higher screening rate included having a primary care physician, a post-high school educational level, and income of more than $25 000 per year. Conclusions and Relevance: Results of this survey study suggest that older male respondents to the 2020 BRFSS survey were overscreened for prostate cancer despite the age cutoff for PSA screening recommended in national guidelines. Discussing the benefits of PSA testing with a clinician was associated with increased screening, underscoring the potential of clinician-level interventions to reduce overscreening in older males.

Prognostic Value of the Intermediate-risk Feature in Men with Favorable Intermediate-risk Prostate Cancer: Implications for Active Surveillance.

Background: Guidelines suggest that active surveillance (AS) may be considered for select patients with favorable intermediate-risk (fIR) prostate cancer. Objective: To compare the outcomes between fIR prostate cancer patients included by Gleason score (GS) or prostate-specific antigen (PSA). Most patients are classified with fIR disease due to either a 3 + 4 = 7 GS (fIR-GS) or a PSA level of 10-20 ng/ml (fIR-PSA). Previous research suggests that inclusion by GS 7 may be associated with worse outcomes. Design setting and participants: We conducted a retrospective cohort study of US veterans diagnosed with fIR prostate cancer from 2001 to 2015. Outcome measurements and statistical analysis: We compared the incidence of metastatic disease, prostate cancer-specific mortality (PCSM), all-cause mortality (ACM), and receipt of definitive treatment between fIR-PSA and fIR-GS patients managed with AS. Outcomes were compared with those of a previously published cohort of patients with unfavorable intermediate-risk disease using cumulative incidence function and Gray's test for statistical significance. Results and limitations: The cohort included 663 men; 404 had fIR-GS (61%) and 249 fIR-PSA (39%). There was no evidence of difference in the incidence of metastatic disease (8.6% vs 5.8%, p = 0.77), receipt of definitive treatment (77.6% vs 81.5%, p = 0.43), PCSM (5.7% vs 2.5%, p = 0.274), and ACM (16.8% vs 19.1%, p = 0.14) between the fIR-PSA and fIR-GS groups at 10 yr. On multivariate regression, unfavorable intermediate-risk disease was associated with higher rates of metastatic disease, PCSM, and ACM. Limitations included varying surveillance protocols. Conclusions: There is no evidence of difference in oncological and survival outcomes between men with fIR-PSA and fIR-GS prostate cancer undergoing AS. Thus, presence of GS 7 disease alone should not exclude patients from consideration of AS. Shared decision-making should be utilized to optimize management for each patient. Patient summary: In this report, we compared the outcomes of men with favorable intermediate-risk prostate cancer in the Veterans Health Administration. We found no significant difference between survival and oncological outcomes.

Patient perspectives of prostate cancer screening vary by race following 2018 guideline changes.

BACKGROUND: The 2018 US Preventive Services Task Force guidelines recommend individualizing prostate cancer screening in 55- to 69-year-old men. Given the higher incidence of prostate cancer in African American (AA) compared to non-Hispanic White (NHW) men, this study compared reported rates of prostate-specific antigen (PSA) screening hypothesizing that it would not be commensurate with the relative risk between these two groups. METHODS: Using the 2020 Behavioral Risk Factor Surveillance System, we identified 43,685 men (40,301 NHW and 3384 AA) interviewed about PSA screening. RESULTS: AA men had an odds ratio (OR) of 0.80 (95% confidence interval [CI], 0.69-0.93; p = .004) of reporting PSA screening; sequentially correcting for access to care, smoking, and age had minimal effect on this finding, but when correcting for income significantly attenuated this difference (OR, 0.95; 95% CI, 0.81-1.12). Further adding education level eliminated the effect size of AA race entirely with OR, 0.99 (95% CI, 0.84-1.17; p = .91). Further analysis found significant interaction between education and race, with college-educated AA men having 1.42 OR of receiving screening compared to college-educated NHW men. CONCLUSIONS: Despite prostate cancer being more common and having higher population-level mortality in AA than NHW men, PSA screening and education patterns do not reflect this increased risk even when adjusting for health access disparities. The authors' findings of significant effect from both income and education suggest that systemic racism is an important factor in the observed difference in PSA screening between AA men and NHW men. LAY SUMMARY: In the United States, prostate cancer is more common in African American men New guidelines from 2018 encourage physicians to consider risk factors in deciding whether or not to recommend screening, but overall African American men continue to be screened at a lower rate than non-Hispanic White men This effect disappears when correcting for income and education level, suggesting that several factors including systemic racism, medical mistrust, and self-advocacy may impact this observed difference.

Renal Functional Outcomes in Patients With Angiomyolipomas: Surveillance vs Embolization vs Nephrectomy.

OBJECTIVE: To investigate renal functional outcomes of surveillance, embolization, and surgery for angiomyolipomas (AML). METHODS: Longitudinal data regarding patients with AML were analyzed retrospectively in this 2-center study. Demographic, radiographic, and functional data were tabulated according to treatment type. Primary outcome was change in renal function from diagnosis to within 6 months postdiagnosis (interim) and to latest glomerular filtration rate (GFR) assessment. RESULTS: 318 patients were diagnosed with AMLs; mean follow-up was 6.2 years. 184 patients (57.9%) were managed with surveillance, 30 (9.4%) underwent embolization, and 103 (32.4%) underwent surgery (91 partial nephrectomy; 12 radical nephrectomy). Baseline characteristics, including tumor size, age, and race differed between the 3 groups (P<.05). Surveilled AMLs were smaller (P<.001) than the intervention groups: 1.9 cm vs 5.4 cm (embolization) and 4.9 cm (surgery). Greater interim decreases in GFR were observed following intervention with embolization (-14.0%) or surgery (-11.8%), when compared with surveillance (-4.1%); however, this was not statistically significant (P=.19). Latest GFR was also reduced more (P=.02) with embolization (-14.1%) and surgery (-14.7%) when compared to surveillance (-6.0%). At latest determination, chronic kidney disease progression by at least one stage occurred in 37.8% overall, including 33.7% of surveilled patients, and was not statistically different across the three cohorts (P=.074). CONCLUSION: Within the study limitations, surveillance appears to be appropriate for most AML patients; embolization and surgical intervention should be reserved for selected patients with large and/or symptomatic AML. Renal functional deterioration is common in patients with AML, whether managed with surveillance, embolization, or surgery. Long-term monitoring of renal function should be obligatory for all AML patients.

Oncologic outcomes of neoadjuvant chemotherapy in patients with micropapillary variant urothelial carcinoma of the bladder.

BACKGROUND: There is lack of consensus about the effectiveness of neoadjuvant platinum-based chemotherapy in patients with micropapillary variant urothelial carcinoma (MVUC) prior to radical cystectomy. We studied the association between neoadjuvant chemotherapy (NAC) and pathologic response (PR) among patients with micropapillary versus non-variant bladder urothelial carcinoma (UC). METHODS: We queried the National Cancer Database to identify patients with localized UC and MVUC from 2004 to 2017. We restricted our analysis to patients who underwent radical cystectomy with or without NAC. We compared clinical, demographic, and pathologic characteristics associated with NAC. We used multivariable logistic regression and propensity score matching to examine the association between NAC and the occurrence of a pathologic complete response (pT0) and pathologic lymph node positivity (pN+). Kaplan Meier analyses and Cox proportional hazards models were used to assess overall survival (OS). We performed analyses among subsets of patients with clinical stage II (cT2) disease, as well as the entire cohort (cT2-T4). RESULTS: We identified 18,761 patients, including 18,027 with non-variant UC and 734 patients with MVUC. Multivariable analysis revealed that NAC use was associated with greater odds of pT0 (9.64[7.62-12.82], P<0.001), and the association did not differ significantly between MVUC and non-variant UC. In a propensity matched analysis of patients with MVUC, NAC use was associated with higher odds of pT0 (OR 4.93 [2.43-13.18] P<0.001), lower odds of pN+ (OR 0.52 [0.26-0.92] P=0.047) and pathologic upstaging (OR 0.63 [0.34-0.97] P=0.042) in all stages. Similar findings were observed with cT2 disease. No significant association was seen between NAC and OS with MVUC (HR 0.89 [0.46-1.10] P=0.63), including the subset of patients with cT2 (HR 0.83 [0.49-1.06] P=0.58). CONCLUSIONS: NAC is associated with similar pathologic and nodal responses in patients with localized MVUC and non-variant UC. Improvements in pathologic findings did not translate into OS in this retrospective hospital-based registry study.

Impact of Metastasectomy on Cancer Specific and Overall Survival in Metastatic Renal Cell Carcinoma: Analysis of the REMARCC Registry.

BACKGROUND: Treatment paradigms for management of metastatic renal cell carcinoma (mRCC) are evolving. We examined impact of surgical metastasectomy on survival across in mRCC stratified by risk-group. METHODS: Multicenter retrospective analysis from the Registry of Metastatic RCC database. The cohort was subdivided utilizing Motzer criteria (favorable-, intermediate-, high-risk). Primary outcome was all-cause mortality (ACM)/overall survival (OS); secondary outcome was cancer-specific mortality (CSM)/cancer-specific survival (CSS). Impact of metastasectomy was analyzed via Cox-Regression analysis adjusting for potential prognostic variables and Kaplan-Meier analysis (KMA) within each risk-group. RESULTS: Four hundred thirty-one patients (59 favorable-risk, 274 intermediate-risk, 98 high-risk; median follow-up 27.2 months) were analyzed. Metastasectomy was performed in 22 (37%), 66 (24%), and 32 (16%) of favorable-, intermediate- and high-risk groups (P = .012). Median number of metastases at diagnosis differed significantly (favorable-risk 2, intermediate-risk 3.4, high-risk 5.1, P < .001). On Cox-regression, high-risk (HR = 1.72, P = .002) was associated with worsened ACM, while metastasectomy was associated with improved ACM (HR = 0.56, P = .005). On KMA, median OS (months) was longer with metastasectomy in favorable- (92.7 vs. 25.8, P = .003) and intermediate-risk (26.3 vs. 20.1, P = .038), but not high-risk (P = .911) groups. Metastasectomy was associated with longer CSS in favorable- (76.1 vs. 32.8, P = .004) but not intermediate- (P = .06) and high-risk (P = .595) groups. CONCLUSIONS: Metastasectomy was independently associated with improved ACM and CSM, as well as improved CSS and OS in favorable- and intermediate-risk mRCC patients. Metastasectomy may be considered as component of multimodal management strategy in favorable and intermediate-risk subgroups. In high-risk patients, metastasectomy should be deferred except in select circumstances.

An evaluation of trends in the representation of patients by age, sex, and diverse race/ethnic groups in bladder and kidney cancer clinical trials.

OBJECTIVES: To determine the representation of women, minorities, and the elderly groups in clinical trials and whether participation has changed over time. METHODS: Retrospective study in the National Cancer Institute (NCI) Clinical Data Update System and Center for Disease Control and Prevention United States Cancer Statistics 2000 to 2019. We compared cancer incidence proportion to proportion of patients enrolled in an NCI trial when stratified by race/ethnicity, sex, and age. We performed multivariable analysis to determine the odds of participating in a clinical trial in 2015 to 2019 when compared to 2000 to 2004. RESULTS: This study included 14,094 patients, 12,169 (86.3%) non-Hispanic White patients, 662 (4.7%) Black patients, and 660 (4.7%) Hispanic patients. There were 3,701 (26.3%) female patients and 10,393 (73.7%) male patients. For bladder cancer clinical trials, Black patients and Hispanic patients were underrepresented in clinical trials compared to Non-Hispanic White patients (odds ratio [OR] 0.71, 95% confidence interval [CI] 0.57-0.88, P = 0.002) and (OR 0.69, 95%CI 0.54-0.88, P = 0.003), respectively. For kidney cancer trials, Black and Hispanic patients were underrepresented in clinical trials compared to Non-Hispanic White patients (OR 0.42, OR 0.33-0.54, P < 0.001) and (OR 0.68, 95% CI 0.55-0.83, P < 0.001), respectively. Women were underrepresented in kidney cancer trials compared to men (OR 0.80, 95% CI 0.72-0.89) and similarly for bladder cancer trials (OR 0.72, 95% CI 0.64-0.81, P < 0.001). For bladder cancer trials, the participation of Black patients over time (OR 1.04, P = 0.814) and female patients over time (OR 1.03, P = 0.741) were unchanged. For kidney cancer trials, the participation of Black patients over time (OR 1.17, P = 0.293) and female patients over time (OR 1.03, P = 0.663) participation was also unchanged. CONCLUSION: In this study of clinical trials in bladder and kidney cancer, we identified that Blacks, Hispanics, and females were underrepresented. Additionally, Black and female participation was unchanged over the span of 20 years.

Germline alterations among Hispanic men with prostate cancer.

BACKGROUND: Little is known about the true rate of pathogenic (P)/likely pathogenic (LP) germline alterations in Hispanic men with prostate cancer as most studies analyzing the prevalence of P/LP germline alterations were performed in a largely non-Hispanic white population (NHW). METHODS: We performed a retrospective analysis of two separate cohorts of men with prostate cancer: (1) a multicenter cohort of 17,256 men who underwent germline testing in a CLIA-certified laboratory and (2) a single-center cohort of all men eligible for germline testing between 2018 and 2020. The proportions of P/LP alterations and variants of uncertain significance (VUS) were computed. Fisher's exact test was used to compare germline alteration rates for significance. A multivariate logistic regression was performed adjusting for demographic and clinical factors to examine factors associated with germline testing. RESULTS: In the multicenter cohort, the rate of P/LP germline alterations among self-reported Hispanic men was 7.1%, which was lower than self-reported NHW men (9.7% vs. 7.1%, p = 0.058), but was not statistically significant. The VUS rate was significantly higher among the Hispanic cohort (21.5% vs. 16.6%, p = 0.005). In the single-center cohort, 136 Hispanic patients were eligible for testing of which 34 underwent germline testing (26.1%, N = 34/136). Of all prostate cancer patients in the single-center cohort undergoing germline testing (n = 173), the rate of P/LP alterations in Hispanic patients was not significantly different compared to NHW patients (14.7% vs. 12.2%, p = 0.77). The rate of VUS in Hispanic patients was significantly higher than that of NHW patients (20.6% vs. 7.2%, p = 0.047). CONCLUSION: The P/LP germline alteration rate in our cohorts was similar between Hispanic and NHW men. The rate of VUS was significantly higher in Hispanic men, a consequence of undertesting in minority populations. These data support that Hispanic men with prostate cancer should be screened for germline testing similar to NHW men.
