Trends in Emergency Department Admissions Due to Renal Colic in the Pediatric Population: A Multicenter Study.

BACKGROUND: Pediatric urolithiasis is relatively uncommon and is generally associated with predisposing anatomic or metabolic abnormalities. In the adult population, emergency department (ED) admissions have been associated with an increase in ambient temperature. The same association has not been evaluated in the pediatric population. OBJECTIVES: To analyze trends in ED admissions due to renal colic in a pediatric population (≤ 18 years old) and to assess the possible effect of climate on ED admissions. METHODS: We conducted a retrospective, multicenter cohort study, based on a computerized database of all ED visits due to renal colic in pediatric patients. The study cohort presented with urolithiasis on imaging during their ED admission. Exact climate data was acquired through the Israeli Meteorological Service (IMS). RESULTS: Between January 2010 and December 2020, 609 patients, ≤ 18 years, were admitted to EDs in five medical centers with renal colic: 318 males (52%), 291 females (48%). The median age was 17 years (IQR 9-16). ED visits oscillated through the years, peaking in 2012 and 2018. A 6% downward trend in ED admissions was noted between 2010 and 2020. The number of ED admissions in the different seasons was 179 in autumn (30%), 134 in winter (22%), 152 in spring (25%), and 144 in summer (23%) (P = 0.8). Logistic regression multivariable analysis associated with ED visits did not find any correlation between climate parameters and ED admissions due to renal colic in the pediatric population. CONCLUSIONS: ED admissions oscillated during the period investigated and had a downward trend. Unlike in the adult population, rates of renal colic ED admissions in the pediatric population were not affected by seasonal changes or rise in maximum ambient temperature.

Does a prior cancer diagnosis impact PSA testing? Results from the National Health Interview Survey.

INTRODUCTION: Prostate-specific antigen (PSA) testing remains a controversial issue. However, most urological guidelines recommend PSA testing in men aged 55-69 through a shared decision-making process with the patient. The impact of prior cancer diagnosis on PSA testing is not well-known. To compare PSA testing in men aged 55-69 years with and without a history of cancer (excluding prostate cancer patients). MATERIALS AND METHODS: Utilizing the National Health Interview Survey (NHIS), a retrospective cross-sectional study during the year 2018 was carried out. Multivariable logistic regression analysis was implemented to demonstrate potential associations with PSA testing and assess the association of cancer history. RESULTS: A total of 2,892 men aged 55-69 years from the NHIS survey who met the inclusion criteria were analyzed. A total of 308 (10.7%) men had a history of cancer (non-prostate). Men with a cancer history had a higher number of PSA tests and more recent testing than men with no previous cancer history. On multivariable analysis, men who were previously diagnosed with cancer had a higher likelihood of undergoing PSA testing compared to men with no history of cancer (OR: 1.87, 95% CI 1.39-2.52, p < 0.0001). CONCLUSIONS: Our data suggest that men aged 55-69 with a history of cancer are more likely to undergo PSA testing than men with no cancer history.

The association of sexual orientation with prostate, breast, and cervical cancer screening and diagnosis.

PURPOSE: Data on heterogeneity in cancer screening and diagnosis rates among lesbians/gays and bisexuals (LGBs) is lacking. Recent studies showed that LGBs have decreased healthcare utilization compared to heterosexual counterparts. Few studies have examined how sexual orientation impacts cancer screening and prevalence. We, therefore, investigated the association between sexual orientation and prevalent sex-specific cancer including prostate (PCa), breast (BC), and cervical (CC) cancer. METHODS: This was a cross-sectional survey-based US study, including men and women aged 18 + from the Health Information National Trends Survey (HINTS) database between 2017 and 2019. The primary endpoint was individual-reported prostate, breast, and cervical cancer screening and prevalence rates among heterosexual and LGB men and women. Multivariable logistic regression analyses assessed association of various covariates with undergoing screening and diagnosis of these cancers. RESULTS: Overall, 4,441 and 6,333 heterosexual men and women, respectively, were compared to 225 and 213 LGB men and women, respectively. LGBs were younger and less likely to be screened for PCa, BC, and CC than heterosexuals. A higher proportion of heterosexual women than lesbian and bisexual women were screened for CC with pap smears (95.36% vs. 90.48% and 86.11%, p ≤ 0.001) and BC with mammograms (80.74% vs. 63.81% and 45.37%, p ≤ 0.001). Similarly, a higher proportion of heterosexual men than gay and bisexual men were screened for PCa with PSA blood tests (41.27% vs. 30.53% and 27.58%, p ≤ 0.001). CONCLUSION: There were more heterosexuals than LGBs screened for CC, BC, and PCa. However, no association between sexual orientation and cancer diagnosis was found. Healthcare professionals should be encouraged to improve cancer screening among LGBs.

Financial Toxicity and Its Association With Prostate and Colon Cancer Screening.

BACKGROUND: The term "financial toxicity" or "hardship" is a patient-reported outcome that results from the material costs of cancer care, the psychological impacts of these costs, and the coping strategies that patients use to deal with the strain that includes delaying or forgoing care. However, little is known about the impact of financial toxicity on cancer screening. We examined the effects of financial toxicity on the use of screening tests for prostate and colon cancer. We hypothesized that greater financial hardship would show an association with decreased prevalence of cancer screening. METHODS: This cross-sectional survey-based US study included men and women aged ≥50 years from the National Health Interview Survey database from January through December 2018. A financial hardship score (FHS) between 0 and 10 was formulated by summarizing the responses from 10 financial toxicity dichotomic questions (yes or no), with a higher score associated with greater financial hardship. Primary outcomes were self-reported occurrence of prostate-specific antigen (PSA) blood testing and colonoscopy for prostate and colon cancer screening, respectively. RESULTS: Overall, 13,439 individual responses were collected. A total of 9,277 (69.03%) people had undergone colonoscopies, and 3,455 (70.94%) men had a PSA test. White, married, working men were more likely to undergo PSA testing and colonoscopy. Individuals who had not had a PSA test or colonoscopy had higher mean FHSs than those who underwent these tests (0.70 and 0.79 vs 0.47 and 0.61, respectively; P≤.001 for both). Multivariable logistic regression models demonstrated that a higher FHS was associated with a decreased odds ratio for having a PSA test (0.916; 95% CI, 0.867-0.967; P=.002) and colonoscopy (0.969; 95% CI, 0.941-0.998; P=.039). CONCLUSIONS: Greater financial hardship is suggested to be associated with a decreased probability of having prostate and colon cancer screening. Healthcare professionals should be aware that financial toxicity can impact not only cancer treatment but also cancer screening.

Does antithrombotic use enable earlier diagnosis of bladder cancer? A brief institutional assessment.

INTRODUCTION: Wallis et al (JAMA 2017) demonstrated use of antithrombotic medications (ATMs) is associated with increased prevalence of hematuria-related complications and subsequent bladder cancer diagnosis within 6 months. Stage of diagnosis was lacking in this highly publicized study. This study examined the association of ATM use on bladder cancer stage at the time of diagnosis. MATERIALS AND METHODS: We completed a retrospective chart review of patients with a bladder cancer diagnosis at our institution. Patient demographics and bladder cancer work up information were assessed. Patients were stratified based on use of ATMs at time diagnosis. Descriptive statistics were completed to identify association between ATM use and stage of bladder cancer diagnosis, as stratified by non-muscle invasive bladder cancer (NMIBC) versus muscle invasive bladder cancer (MIBC). RESULTS: A total of 1052 patient charts were reviewed. Eight hundred and forty-four were included and 208 excluded due to unavailability of diagnosis history. At diagnosis, 357 (42.3%) patients were taking ATMs. Patients on ATMs presented with NMIBC at similar rates as patients not taking ATMs (81.2% vs. 77.8%, p = 0.23). Subgroup analysis by ATM class similarly demonstrated no statistically significant differences in staging. CONCLUSION: While Wallis et al established that patients on blood thinners who present with hematuria are more likely to be diagnosed with genitourinary pathology, this factor does not appear to enable an earlier diagnosis of bladder cancer. Future study may assess hematuria at presentation (gross, microscopic), type of blood thinners, and low versus high risk NMIBC presentation.

Is there an association between a history of military service and cancer diagnosis? Results from a US national-level study of self-reported outcomes.

PURPOSE: To examine cancer prevalence in men with and without military service history, using national-level self-reported outcomes. METHODS: A cross-sectional survey-based US study, including men aged 18 and above from the Health Information National Trends Survey database between 2011 and 2014. The primary endpoint was self-reported cancer prevalence. Multivariable logistic regression analyses assessed the association of various covariates with the prevalence of cancer. RESULTS: A total of 4,527 men were analyzed, with 1,352 (29.9%) reporting a history of military service. Compared to men with no military service history, men with a military service history were older (median of 65 [IQR 56, 74] vs. 53 [IQR 41, 62] years, p < 0.0001), more commonly Caucasian (71.4% vs. 61.4%, p < 0.0001), born in the US (95.6% vs. 79.5%, p < 0.0001), attained higher education level and annual household income (p < 0.0001), and consisted of more smokers(58.3% vs. 44.5%, p < 0.0001). The age-adjusted comparison demonstrated a higher cancer prevalence in men with military service history (20.5% vs. 7.6%, p < 0.0001). Specifically, genitourinary, dermatological, gastrointestinal, and hematological cancers were generally more prevalent. Adjusting for all available confounders, multivariable models showed that military service history was associated with 1.56 (95% CI 1.20-2.03), and 1.57 (95% CI 1.07-2.31) increased odds of having any cancer, and specifically genitourinary cancer, respectively. CONCLUSIONS: Further research is needed to ascertain whether the association between military service and increased cancer diagnosis results from better screening programs or increased exposure to risk factors during military service.

Can post-treatment free PSA ratio be used to predict adverse outcomes in recurrent prostate cancer?

OBJECTIVES: To assess whether free PSA ratio (FPSAR) at biochemical recurrence (BCR) can predict metastasis, castrate-resistant prostate cancer (CRPC), and cancer-specific survival (CSS), following therapy for localised disease. PATIENTS AND METHODS: A single-centre retrospective cohort study (NCT03927287) including a discovery cohort composed of patients with an FPSAR after radical prostatectomy (RP) or radiotherapy (RT) between 2000 and 2017. For validation, an independent Biobank cohort of patients with BCR after RP was tested. Using a defined FPSAR cut-off, the metastasis-free-survival (MFS), CRPC-free survival, and CSS were compared. Multivariable Cox models determined the association between post-treatment FPSAR, metastases, and CRPC. RESULTS: Overall, 822 patients (305 RP- and 363 RT-treated patients and 154 Biobank patients) were analysed. In the RP cohort, a total of 272/305 (89.1%) and 33/305 (10.9%) had a FPSAR test incidentally and reflexively, respectively. In the RT cohort, 155/363 (42.7%) and 208/263 (57.3%) had a FPSAR test incidentally and reflexively, respectively. However, in the prospective Biobank RP cohort, FPSAR testing was done on all samples of patients diagnosed with BCR. A FPSAR cut-off of 0.10 was determined using receiver operating characteristic analyses in both the RP and RT cohorts. A FPSAR of <0.10 resulted in longer median MFS (14.8 vs 9.3 years and 14.8 vs 13 years, respectively), and longer median CRPC-free survival (median not reached vs 9.9 years and 20.7 vs 13.8 years, respectively). Multivariable analyses showed that a FPSAR of ≥0.10 was associated with increased metastasis in the RP cohort (hazard ratio [HR] 1.915, 95% confidence interval [CI] 1.241-2.955) and RT cohort (HR 1.754, 95% CI 1.112-2.769), and increased CRPC in the RP cohort (HR 2.470, 95% CI 1.493-4.088). Findings were validated in the Biobank cohort. CONCLUSIONS: A post-treatment FPSAR of ≥0.10 is associated with more aggressive disease, suggesting a potentially novel role for this biomarker.

A High Percent Free Prostate Specific Antigen in the Setting of Biochemical Recurrence after Radical Prostatectomy is Associated with Poorer Outcomes: A Validation Study Using Prospectively Collected Biobank Specimens.

PURPOSE: The role of percent free prostate specific antigen (%fPSA) in patients who have undergone radical prostatectomy and subsequently experienced disease relapse is unclear. We previously conducted 2 retrospective studies and found %fPSA 15 or greater in the setting of biochemical recurrence confers more aggressive disease. To validate that finding we used biobank specimens collected prospectively when patients were first diagnosed with biochemical recurrence. MATERIALS AND METHODS: Biobank specimens of patients with undetectable prostate specific antigen after radical prostatectomy and subsequent biochemical recurrence (prostate specific antigen 0.1 ng/ml or greater) were analyzed for %fPSA. Patients were stratified according to the %fPSA cutoff of 15. Univariable and multivariable logistic regression analysis was performed to predict covariates associated with a higher %fPSA. Cox proportional hazard models were performed to evaluate the prognostic effect of %fPSA on androgen deprivation therapy-free survival, metastasis-free survival, castration resistant-free survival and cancer specific survival. RESULTS: A total of 154 men were included in the study, of whom 126 (82%) had %fPSA less than 15 and 28 (18%) had %fPSA 15 or greater. Median followup for %fPSA less than 15 and %fPSA 15 or greater was 75 and 69 months, respectively. Patients with %fPSA 15 or greater had increased hazard of receiving androgen deprivation therapy (43% vs 25%, adjusted HR 2.40, 95% CI 1.12-5.11), metastatic disease (21% vs 7.9%, adjusted HR 4.10, 95% CI 1.11-15.2) and castration resistant prostate cancer (14% vs 4.0%, unadjusted HR 4.14, 95% CI 1.11-15.5) vs %fPSA less than 15, respectively. CONCLUSIONS: Patients with %fPSA 15 or greater were started on androgen deprivation therapy earlier, and they had progression to castration resistant prostate cancer and metastatic stage earlier. %fPSA 15 or greater in the setting of biochemical recurrence after radical prostatectomy is an indicator of a more aggressive disease. Unlike in the diagnostic setting, a higher %fPSA portends a worse clinical outcome.

Does Time Spent on Active Surveillance Adversely Affect the Pathological and Oncologic Outcomes in Patients Undergoing Delayed Radical Prostatectomy?

PURPOSE: Pathological and oncologic outcomes of delayed radical prostatectomy following prostate cancer active surveillance are not well established. We determined the pathological and oncologic outcomes of favorable risk, Grade Group 1, prostate cancer managed with active surveillance and progressing to radical prostatectomy for clinically significant prostate cancer (Grade Group 2 or greater). MATERIALS AND METHODS: Between 1992 and 2015, 170 men with favorable risk prostate cancer underwent delayed radical prostatectomy for clinically significant prostate cancer (ASRP) at the Princess Margaret Cancer Centre. Pathological and oncologic outcomes of the ASRP cohort were compared with a matched cohort treated with up-front radical prostatectomy (405) immediately before surgery. Biochemical recurrence-free survival, overall survival and cancer specific survival were compared. We examined the association between delayed radical prostatectomy and adverse pathology at radical prostatectomy and biochemical recurrence using logistic and Cox regression analyses, respectively. RESULTS: Median time spent on active surveillance before radical prostatectomy was 31.0 months. At radical prostatectomy pT3 (extraprostatic extension, seminal vesicle invasion), positive surgical margin and pN1 rates were comparable between the 2 cohorts. Median followup after radical prostatectomy was 5.6 years. The 5-year biochemical recurrence-free survival rate in the ASRP cohort and up-front radical prostatectomy cohort were 85.8% and 82.4%, respectively (p=0.38). Overall survival and cancer specific survival were comparable between the 2 groups. Delayed radical prostatectomy was not associated with adverse pathological outcomes and biochemical recurrence on regression analyses. CONCLUSIONS: Curative intent radical prostatectomy after a period of active surveillance results in excellent pathological and oncologic outcomes at 5 years. A period of active surveillance does not result in inferior outcomes compared to patients with similar risk characteristics undergoing up-front radical prostatectomy.

Comparison of Magnetic Resonance Imaging and Transrectal Ultrasound Informed Prostate Biopsy for Prostate Cancer Diagnosis in Biopsy Naïve Men: A Systematic Review and Meta-Analysis.

PURPOSE: Multiparametric magnetic resonance imaging with informed targeted biopsies has changed the paradigm of prostate cancer diagnosis. Randomized studies have demonstrated a diagnostic benefit of clinical significance for targeted biopsy compared to standard systematic biopsies. We evaluated whether multiparametric magnetic resonance imaging informed targeted biopsy has superior diagnosis rates of any, clinically significant, high grade and clinically insignificant prostate cancer compared to systematic biopsy in biopsy naïve men. MATERIALS AND METHODS: Data were searched in Medline®, Embase®, Web of Science and Evidence-Based Medicine Reviews-Cochrane Database of Systematic Reviews from database inception until 2019. Studies were selected by 2 authors independently, with disagreements resolved by consensus with a third author. Overall 1,951 unique references were identified and 100 manuscripts underwent full-text review. Data were pooled using random effects models. The meta-analysis is reported according to the PRISMA statement and the study protocol is registered with PROSPERO (CRD42019128468). RESULTS: Overall 29 studies (13,845 patients) were analyzed. Compared to systematic biopsy, use of multiparametric magnetic resonance imaging informed targeted biopsy was associated with a 15% higher rate of any prostate cancer diagnosis (95% CI 10-20, p <0.00001). This relationship was not affected by the study methodology (p=0.11). Diagnoses of clinically significant and high grade prostate cancer were more common in the multiparametric magnetic resonance imaging informed targeted biopsy group (risk difference 11%, 95% CI 0-20, p=0.05 and 2%, 95% CI 1-4, p=0.005, respectively) while there was no difference in diagnosis of clinically insignificant prostate cancer (risk difference 0, 95% CI -3 to 3, p=0.96). Notably, the exclusion of systematic biopsy in the multiparametric magnetic resonance imaging informed targeted biopsy arm significantly modified the association between a multiparametric magnetic resonance imaging strategy and lower rates of clinically insignificant prostate cancer diagnosis (p=0.01) without affecting the diagnosis rates of clinically significant or high grade prostate cancer. CONCLUSIONS: Compared to systematic biopsy a multiparametric magnetic resonance imaging informed targeted biopsy strategy results in a significantly higher diagnosis rate of any, clinically significant and high grade prostate cancer. Excluding systematic biopsy from multiparametric magnetic resonance imaging informed targeted biopsy was associated with decreased rates of clinically insignificant prostate cancer diagnosis without affecting diagnosis of clinically significant or high grade prostate cancer.

Tubeless supra-costal percutaneous nephrolithotomy is associated with significantly less hydrothorax: a prospective randomized clinical study.

OBJECTIVES: To evaluate prospectively whether a tubeless (JJ stent-only) percutaneous nephrolithotomy (PCNL) might reduce the risk of hydrothorax, compared to an approach where a nephrostomy tube is left. MATERIALS AND METHODS: We conducted a two-arm open-label prospective randomized study (NCT02036398) comparing tubeless supra-costal PCNL (with a JJ stent only) to standard PCNL (with nephrostomy tube and JJ stent) using intention-to-treat (ITT) and per-protocol (PP) analyses. All patients underwent a standard single-stage prone supra-costal procedure with single-tract access. Complication data were collected according to the Clavien-Dindo grading system. The primary endpoint was the rate of hydrothorax, and secondary endpoints included stone-free rate (SFR) and complication rate. Multivariable logistic regression analysis identified factors associated with hydrothorax formation. RESULTS: Out of 101 patients approached, 75 were finally analysed. No differences were observed between the two arms with regard to baseline demographic and stone characteristics. The mean largest stone size ranged between 23 and 24.2 mm. No significant difference was seen in the mean operating time and length of hospital stay. The incidence of hydrothorax was significantly higher in the nephrostomy group in comparison to the tubeless group (37.8% vs 15.8%, P = 0.031, and 38.4% vs 13.8%, P = 0.016, in the ITT and PP analyses, respectively). The SFR and complication rate were similar in both groups using the ITT and PP analyses. Multivariable logistic regression analysis showed that nephrostomy tube placement was the only covariate associated in a statistically significant manner to hydrothorax (odds ratio 3.628, 95% confidence interval 1.073-12.265; P = 0.038). CONCLUSION: The rate of hydrothorax in supra-costal PCNL is associated with the type of postoperative drainage left. When possible, a tubeless approach should be applied as it may confer a lower risk of hydrothorax.

Twitter and academic Urology in the United States and Canada: a comprehensive assessment of the Twitterverse in 2019.

OBJECTIVE: To provide the first comprehensive analysis of the Twitterverse amongst academic urologists and programmes in North America. METHODS: Using national accreditation and individual programme websites, all active urology residency programmes (USA and Canada) and academic Urology faculty at these programmes were identified. Demographic data for each programme American Urological Association [AUA] section, resident class size) and physician (title, fellowship training, Scopus Hirsch index [H-index] and citations) were documented. Twitter metrics (Twitter handle, date joined, # tweets, # followers, # following, likes) for programmes and physicians were catalogued (data capture: March-April 2019). Descriptive analyses and temporal trends in Twitter utilisation amongst programmes and physicians were assessed. Multivariable logistic regression was used to identify predictors of Twitter use. RESULTS: In all, 156 academic programmes (143 USA, 13 Canada) and 2214 academic faculty (2015 USA, 199 Canada) were identified. Twitter utilisation is currently 49.3% and 34.1% amongst programmes and physicians, respectively, and continues to increase. On multivariable analysis, programmes with 3-5 residents/year and programmes with a higher percentage of faculty Twitter engagement were more likely to have Twitter accounts. From a physician perspective, those with fellowship training, lower academic rank (Clinical Instructor, Assistant Professor, Associate Professor vs Professor) and higher H-indices were more likely to have individual Twitter accounts. CONCLUSION: There is a steady increase in Twitter engagement amongst Urology programmes and academic physicians. Faculty Twitter utilisation is an important driver of programme Twitter engagement. Twitter social media activity is strongly associated with academic productivity, and may in fact drive academic metrics. Within Urology, social media presence appears to be proportional to academic activity.

Salvage radical prostatectomy following focal therapy: functional and oncological outcomes.

OBJECTIVES: To report the oncological and functional outcomes of salvage radical prostatectomy (sRP) after focal therapy (FT). PATIENTS AND METHODS: A retrospective review of all patients who underwent sRP after FT was performed. Clinical and pathological outcomes focussed on surgical complications, oncological, and functional outcomes. RESULTS: In all, 34 patients were identified. The median (interquartile range [IQR]) age was 61 (8.25) years. FT modalities included high-intensity focussed ultrasound (19 patients), laser ablation (13), focal brachytherapy (one) and cryotherapy (one). The median (IQR) time from FT to recurrence was 10.9 (17.6) months. There were no rectal or ureteric injuries. Two (5.9%) patients had iatrogenic cystotomies and four (11.8%) developed bladder neck contractures. The mean (sd) hospital stay was 2.5 (2.1) days. The T-stage was pT2 in 14 (41.2%) patients, pT3a in 16 (47.1%), and pT3b in four (11.8%). In all, 13 (38%) patients had positive surgical margins (PSMs). Six (17.6%) patients received adjuvant radiotherapy (RT). At a mean follow-up of 4.3 years, seven (20.6%) patients developed biochemical recurrence (BCR), and of these, six (17.6%) patients required salvage RT. PSMs were associated with worse BCR-free survival (hazard ratio 6.624, 95% confidence interval 2.243-19.563; P < 0.001). The median (IQR) preoperative International Prostate Symptom Score and International Index of Erectile Function score was 7 (4.5-9.5) and 23.5 (15.75-25) respectively, while in the final follow-up the median (IQR) values were 7 (3.5-11) and 6 (5-12.25), respectively (P = 0.088 and P < 0.001). At last follow-up, 31 (91.2%) patients were continent, two (5.9%) had moderate (>1 pad/day) incontinence, and one (2.9%) required an artificial urinary sphincter. CONCLUSIONS: sRP should be considered as an option for patients who have persistent clinically significant prostate cancer or recurrence after FT. PSMs should be recognised as a risk for recurrent disease after sRP.

Gender-based psychological and physical distress differences in patients diagnosed with non-metastatic renal cell carcinoma.

OBJECTIVES: To analyze gender-based differences in distress symptoms in patients with non-metastatic renal cell carcinoma (RCC) at different stages of disease. METHODS: The Edmonton Symptom Assessment System-revised (ESAS-r) questionnaire includes a physical (PHSDSS) and a psychological distress sub-score (PDSS). The ESAS-r was used to measure psychological and physical distress symptoms in localized RCC patients in a major cancer referral center between 2014 and 2017 at four predefined time points: (a) diagnosis, (b) biopsy, (c) surgery, and (d) last follow-up. Results were gender stratified, and multivariable linear regression models were used to determine associations with increased sub-scores. RESULTS: Overall, 495 patients were included with 37.2% females. No significant gender differences were seen in mean age, relevant clinical parameters, and treatment. PDSS was significantly higher in females after diagnosis (8.5 vs. 5.1, p = 0.018), biopsy (8.9 vs. 4.1, p = 0.003), and surgery (6.5 vs. 4.4, p = 0.007), while being similar at the last follow-up. The multivariable model demonstrated a statistically significant association of female gender with higher PDSS after diagnosis (B = 3.755, 95% CI 0.761-6.750), biopsy (B = 6.076, 95% CI 2.701-9.451), and surgery (B = 1.974, 95% CI 0.406-3.542). PHSDSS was significantly higher in females after biopsy (10.0 vs. 5.7, p = 0.028) and surgery (8.6 vs. 6.1, p = 0.022). In the multivariable model, female gender conferred a higher PHSDSS only after surgery (B = 2.384, 95% CI 0.208-4.560). CONCLUSIONS: Gender-associated psychological distress differences exist in non-metastatic RCC patients throughout treatment, while dissipating at last follow-up. Emphasis should be placed on screening for distress symptoms and providing psychological support continuously, particularly for female patients.

Predictors of prostate-specific antigen testing in men aged ≥55 years: A cross-sectional study based on patient-reported outcomes.

OBJECTIVES: To examine the predictors of prostate-specific antigen discussion with a physician and prostate-specific antigen testing in men aged ≥55 years. METHODS: Utilizing the USA Health Information National Trends Survey, 4th Ed., a cross-sectional study from 2011 to 2014 was carried out to analyze the factors predicting prostate-specific antigen testing and discussion in men ≥55 years. Associations between each covariate and prostate-specific antigen discussion/testing were determined. Multivariable logistic regression models were used to determine clinically relevant predictors of prostate-specific antigen discussion/testing. Due to multiple comparisons, the Bonferroni correction was used. RESULTS: A total of 2731 men included in the Health Information National Trends Survey were analyzed. Several socioeconomic parameters were found to increase the likelihood of men aged ≥55 years to undergo prostate-specific antigen testing: living with a spouse, a higher level of education (college graduate or above), a higher income (>$50 000 annually) and previous history of any cancer. In contrast, current smokers were less likely to undergo prostate-specific antigen testing. Having a prostate-specific antigen discussion with a physician was more likely for men surveyed in 2014, for men who were living with a spouse, who had a higher annual income (>$50 000 annually) and those with a history of any cancer. CONCLUSIONS: Significant inequalities in prostate-specific antigen testing and discussion exist among men in the USA, mainly driven by socioeconomic factors. Ideally, prostate-specific antigen testing and discussion should be based on relevant clinical factors with a shared decision-making approach for every man. Therefore, a better understanding of the socioeconomic factors influencing prostate-specific antigen testing/discussions can inform strategies to reduce existing gaps in care.

The who, when, and why of primary adrenal malignancies: Insights into the epidemiology of a rare clinical entity.

BACKGROUND: Primary malignancies of the adrenal glands are rare. Epidemiologic assessment of primary adrenal malignancies is lacking and has been limited to case reports and series. Population-level data can provide a better understanding of the incidence, distribution, and prognostic factors associated with these rare malignancies. METHODS: The Surveillance, Epidemiology, and End Results database (1973-2013) was queried for all patients who were diagnosed with primary adrenal malignancies, categorized in 5 histologic groups: adrenocortical carcinoma (ACC), pheochromocytoma and paraganglioma (PH), neuroblastoma (NE), non-Hodgkin lymphoma (NHL), and sarcoma (SA). Age-adjusted incidence, distribution trends, and cancer-specific survival (CSS) for each group were analyzed. RESULTS: In total, 4695 patients with primary adrenal malignancies were identified, including 2057 with ACC, 512 with PH, 1863 with NE, 202 with NHL, and 61 with SA. The age-adjusted incidence of all 5 histologic subtypes was rising. Age at presentation differed substantially by histologic group: NE was the most prevalent during the first decade of life, whereas ACC predominated after age 30 years, and NHL outnumbered PH after age 70 years. Patient-specific factors were not associated with advanced disease at the time of presentation. The 5-year CSS rate for each histologic subtype was 38% for ACC, 69% for PH, 64% for NE, 38% for NHL, and 42% for SA. Survival outcomes for patients with ACC, NHL, PH and SA remained unchanged over the 40-year study period. Multimodal therapy was associated with higher CSS in patients with NE. CONCLUSIONS: This first population-level analysis of all primary adrenal malignancies provides important initial data regarding presentation and clinical outcomes. Notably, except for patients with NE, the survival of patients with these rare cancers has not improved over the past 40 years.

Cancer diagnosis and risk of suicide after accounting for prediagnosis psychiatric care: A matched-cohort study of patients with incident solid-organ malignancies.

BACKGROUND: Previous studies have demonstrated an association between a diagnosis of cancer and the risk of suicide; however, they failed to account for psychiatric care before a cancer diagnosis, which may confound this relationship. The objective of this study was to assess the effect of a cancer diagnosis on the risk of suicide, accounting for prediagnosis psychiatric care utilization. METHODS: All adult residents of Ontario, Canada who were diagnosed with cancer (1 of prostate, breast, colorectal, melanoma, lung, bladder, endometrial, thyroid, kidney, or oral cancer) between 1997 and 2014 were identified. Noncancer controls were matched 4:1 based on sociodemographics, including a psychiatric utilization gradient (PUG) score (with 0 indicating none; 1, outpatient; 2, emergency department; and 3, hospital admission). A marginal, cause-specific hazard model was used to assess the effect of cancer on the risk of suicidal death. RESULTS: Among 676,470 patients with cancer and 2,152,682 matched noncancer controls, there were 8.2 and 11.4 suicides per 1000 person-years of follow-up, respectively. Patients with cancer had an overall higher risk of suicidal death compared with matched patients without cancer (hazard ratio, 1.34; 95% CI, 1.22-1.48). This effect was pronounced in the first 50 months after cancer diagnosis (hazard ratio, 1.60; 95% CI, 1.42-1.81); patients with cancer did not demonstrate an increased risk thereafter. Among individuals with a PUG score 0 or 1, those with cancer were significantly more likely to die of suicide compared with controls. There was no difference in suicide risk between patients with cancer and controls for those who had a PUG score of 2 or 3. CONCLUSIONS: A cancer diagnosis is associated with increased risk of death from suicide compared with the general population even after accounting for precancer diagnosis psychiatric care utilization. The specific factors underlying the observed associations remain to be elucidated.

The impact of psychiatric utilisation prior to cancer diagnosis on survival of solid organ malignancies.

BACKGROUND: Among patients with cancer, prior research suggests that patients with mental illness may have reduced survival. The objective was to assess the impact of psychiatric utilisation (PU) prior to cancer diagnosis on survival outcomes. METHODS: All residents of Ontario diagnosed with one of the top 10 malignancies (1997-2014) were included. The primary exposure was psychiatric utilisation gradient (PUG) score in 5 years prior to cancer: 0: none, 1: outpatient, 2: emergency department, 3: hospital admission. A multivariable, cause-specific hazard model was used to assess the effect of PUG score on cancer-specific mortality (CSM), and a Cox proportional hazard model for effect on all-cause mortality (ACM). RESULTS: A toal of 676,125 patients were included: 359,465 (53.2%) with PUG 0, 304,559 (45.0%) PUG 1, 7901 (1.2%) PUG 2, and 4200 (0.6%) PUG 3. Increasing PUG score was independently associated with worse CSM, with an effect gradient across the intensity of pre-diagnosis PU (vs PUG 0): PUG 1 h 1.05 (95% CI 1.04-1.06), PUG 2 h 1.36 (95% CI 1.30-1.42), and PUG 3 h 1.73 (95% CI 1.63-1.84). Increasing PUG score was also associated with worse ACM. CONCLUSIONS: Pre-cancer diagnosis PU is independently associated with worse CSM and ACM following diagnosis among patients with solid organ malignancies.

Long-term oncological outcomes of patients with paratesticular sarcoma.

OBJECTIVES: To present long-term oncological outcomes of patients with paratesticular sarcoma treated by a multidisciplinary team. PATIENTS AND METHODS: Patients managed at the Princess Margaret Cancer Centre, between 1990 and 2012, were analysed. A sarcoma expert performed central pathology review. Kaplan-Meier graphs compared local recurrence (LR), metastasis, and overall survival (OS) of patients treated with hemiscrotectomy vs those who did not. Univariable Cox proportional hazards analysis was performed to delineate predictors of LR, metastasis, and OS. RESULTS: Overall, 51 patients with a median (interquartile range) follow-up of 132 (51.6-226.8) months were analysed. At presentation, 92.2% (47 patients) had localised disease. Only five patients (9.8%) had undergone initially planned hemiscrotectomy. Completion and salvage hemiscrotectomy was performed in 25 (54.3%) and seven (15.2%) patients, respectively. Recurrence and metastasis occurred in 12 (25.5%) and 10 patients (19.6%), respectively. At the last follow-up, 21.6% (11 patients) had died, with eight dying from their disease. Kaplan-Meyer graphs demonstrated that hemiscrotectomy improved LR (median not reached vs 62.4 months, log-rank P = 0.008) and OS (median not reached vs 168 months, log-rank P = 0.081). Univariable analysis found hemiscrotectomy to be associated with a lower LR rate (hazard ratio [HR] 0.21, P = 0.02), whilst positive margins at initial surgery were associated with increased LR (HR 4.81, P = 0.047). No metastasis predictors were found, but age (HR 1.04, 95% confidence interval [CI] 1.0-1.08; P = 0.02) and non-localised disease at presentation (HR5.17, 95% CI 1.33-20.06; P = 0.017) were associated with worse OS. CONCLUSION: Paratesticular sarcoma is a rare tumour, predominantly manifesting as localised disease. Most patients receive an initial suboptimal oncological surgery. Improved long-term outcomes are demonstrated following early hemiscrotectomy.

Predictors of surgical site infection after radical cystectomy: should we enhance surgical antibiotic prophylaxis?

PURPOSE: To compare surgical site infections (SSI) rate after radical cystectomy (RC) over time and ascertain whether antibiotic prophylaxis should be enhanced. METHODS: All medical records of RC patients in a single tertiary uro-oncology center between 2007 and 2017 were analyzed. SSI was defined using the criteria of the US Centers for Disease Control and Prevention. All bacterial culture results and antimicrobial resistance rates were recorded. Lastly, multivariable logistic regression analysis was performed to ascertain SSI predictors. RESULTS: RC was performed in 405 patients, of which 96 (23.7%) developed SSI. No differences were demonstrated in the mean age, gender, NIDDM prevalence, neoadjuvant chemotherapy, positive preoperative urine culture, bowel preparation, and surgery time between both groups. However, statistically significant higher median BMI, age-adjusted Charlson Comorbidity score, usage of ceftriaxone preoperatively, and intensive care unit (ICU) hospitalization were noted in SSI patients. Overall, 62/96 (63.5%) SSI patients had a positive wound culture, with only 16.7% of the pathogens being sensitive to their perioperative antibiotics. Lastly, on multivariable analysis rising BMI, preoperative ceftriaxone and ICU hospitalization were associated with a higher SSI rate. CONCLUSIONS: Preoperative BMI reduction, and maximal preoperative medical optimization in an attempt to lower ICU admittance rates, should be part of the ideal strategy for lowering SSI rates. Additionally, preoperative antibiotics should be enhanced to harbor-wide spectrum coverage, based on local resistance rates.
