Abstract
PURPOSE/OBJECTIVE(S) The combination of immunotherapy and single-fraction stereotactic radiosurgery (SRS) for treatment of metastatic brain disease has yielded symptomatic radiation necrosis rates as high as 20% (PMID: 29327059). Consequently, the Radiosurgery Dose Reduction for Brain Metastases on Immunotherapy (RADREMI) multicenter phase I trial (registered at clinicaltrials.gov, NCT04047602) was created to address whether reduced-dose SRS can improve morbidity without compromising efficacy. In this report we present our one-year findings. MATERIALS/METHODS Eligibility for RADREMI enrollment required brain metastases patients with: a) Histologically-confirmed primary malignancy, b) Receipt of immunotherapy within 30 days of SRS, c) 1-10 MRI-visible brain metastases, d) Estimated median survival of at least 6 months (via disease-specific graded prognostic assessment), and e) No history of whole brain radiation therapy. Reduced-dose SRS utilized 18 Gy for lesions 0-2 cm, 14 Gy for lesions 2.1-3 cm, and 12 Gy for lesions 3.1-4 cm. Symptomatic radiation necrosis was defined as imaging findings consistent with radiation necrosis combined with clinical symptoms requiring steroid administration and/or operative intervention. Local control was defined by Response Assessment in Neuro-Oncology (RANO) criteria. RESULTS From December 18, 2019 to June 30, 2022, 54 lesions in 17 patients were treated on RADREMI with at least one-year of follow-up. One-year local control occurred in 52 of 54 lesions and in 15 of 17 patients, yielding control rates of 96% per lesion and 88% per patient. Radiographic radiation necrosis occurred in 2 of 54 lesions (4%). No symptomatic radiation necrosis occurred. CONCLUSION Our findings of concurrent immunotherapy + reduced-dose SRS at one-year post-treatment revealed excellent local control (96%) with no symptomatic radiation necrosis, and minimal radiographic radiation necrosis. These results attest to the durability of the safety and efficacy of reduced-dose SRS with immunotherapy for metastatic brain disease.

Abstract
Background Cardiovascular disease (CVD) incidence is higher in men with prostate cancer (PC) than without. Objectives We describe the rate and correlates of poor cardiovascular risk factor control among men with PC. Methods We prospectively characterized 2,811 consecutive men (mean age 68 ± 8 years) with PC from 24 sites in Canada, Israel, Brazil, and Australia. We defined poor overall risk factor control as ≥3 of the following: suboptimal low-density lipoprotein cholesterol (>2 mmol/L if Framingham Risk Score [FRS] ≥15 and ≥3.5 mmol/L if FRS <15), current smoker, physical inactivity (<600 MET min/wk), suboptimal blood pressure (BP) (≥140/90 mm Hg if no other risk factors, systolic BP ≥120 mm Hg if known CVD or FRS ≥15, and ≥130/80 mm Hg if diabetic), and waist:hip ratio >0.9. Results Among participants (9% with metastatic PC and 23% with pre-existing CVD), 99% had ≥1 uncontrolled cardiovascular risk factor, and 51% had poor overall risk factor control. Not taking a statin (odds ratio [OR]: 2.55; 95% CI: 2.00-3.26), physical frailty (OR: 2.37; 95% CI: 1.51-3.71), need for BP drugs (OR: 2.36; 95% CI: 1.84-3.03), and age (OR per 10-year increase: 1.34; 95% CI: 1.14-1.59) were associated with poor overall risk factor control after adjustment for education, PC characteristics, androgen deprivation therapy, depression, and Eastern Cooperative Oncology Group functional status. Conclusions Poor control of modifiable cardiovascular risk factors is common in men with PC, highlighting the large gap in care and the need for improved interventions to optimize cardiovascular risk management in this population.

Abstract
BACKGROUND The first interim analysis of the KEYNOTE-564 study showed improved disease-free survival with adjuvant pembrolizumab compared with placebo after surgery in patients with clear cell renal cell carcinoma at an increased risk of recurrence. The analysis reported here, with an additional 6 months of follow-up, was designed to assess longer-term efficacy and safety of pembrolizumab versus placebo, as well as additional secondary and exploratory endpoints. METHODS In the multicentre, randomised, double-blind, placebo-controlled, phase 3 KEYNOTE-564 trial, adults aged 18 years or older with clear cell renal cell carcinoma with an increased risk of recurrence were enrolled at 213 hospitals and cancer centres in North America, South America, Europe, Asia, and Australia. Eligible participants had an Eastern Cooperative Oncology Group performance status of 0 or 1, had undergone nephrectomy 12 weeks or less before randomisation, and had not received previous systemic therapy for advanced renal cell carcinoma. Participants were randomly assigned (1:1) via central permuted block randomisation (block size of four) to receive pembrolizumab 200 mg or placebo intravenously every 3 weeks for up to 17 cycles. Randomisation was stratified by metastatic disease status (M0 vs M1), and the M0 group was further stratified by ECOG performance status and geographical region. All participants and investigators involved in study treatment administration were masked to the treatment group assignment. The primary endpoint was disease-free survival by investigator assessment in the intention-to-treat population (all participants randomly assigned to a treatment). Safety was assessed in the safety population, comprising all participants who received at least one dose of pembrolizumab or placebo. As the primary endpoint was met at the first interim analysis, updated data are reported without p values. This study is ongoing, but no longer recruiting, and is registered with ClinicalTrials.gov, NCT03142334. FINDINGS Between June 30, 2017, and Sept 20, 2019, 994 participants were assigned to receive pembrolizumab (n=496) or placebo (n=498). Median follow-up, defined as the time from randomisation to data cutoff (June 14, 2021), was 30·1 months (IQR 25·7-36·7). Disease-free survival was better with pembrolizumab compared with placebo (HR 0·63 [95% CI 0·50-0·80]). Median disease-free survival was not reached in either group. The most common all-cause grade 3-4 adverse events were hypertension (in 14 [3%] of 496 participants) and increased alanine aminotransferase (in 11 [2%]) in the pembrolizumab group, and hypertension (in 13 [3%] of 498 participants) in the placebo group. Serious adverse events attributed to study treatment occurred in 59 (12%) participants in the pembrolizumab group and one (<1%) participant in the placebo group. No deaths were attributed to pembrolizumab. INTERPRETATION Updated results from KEYNOTE-564 support the use of adjuvant pembrolizumab monotherapy as a standard of care for participants with renal cell carcinoma with an increased risk of recurrence after nephrectomy.

Abstract
BACKGROUND Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications. METHODS We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC). FINDINGS In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]). INTERPRETATION In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required. FUNDING British Journal of Surgery Society.

Abstract
Darier's disease (also known as keratosis follicularis or dyskeratosis follicularis) is an autosomal dominant inherited disorder which manifests as hyperkeratotic greasy papules in the first or second decade of life. Aside from symptom management and behavioral modifications to avoid triggers, there are currently no validated treatments for Darier's disease (DD). However, a variety of treatments have been proposed in the literature including retinoids, steroids, vitamin D analogs, photodynamic therapy, and surgical excision. The purpose of this review article is to identify therapeutic options for treating DD and to outline the evidence underlying these interventions. A search was conducted in Medline for English language articles from inception to July 4, 2020. Our search identified a total of 474 nonduplicate studies, which were screened by title and abstract. Of these, 155 full text articles were screened against inclusion/exclusion criteria, and 113 studies were included in our review. We identified Grade B evidence for the following treatments of DD: oral acitretin, oral isotretinoin, systemic Vitamin A, topical tretinoin, topical isotretinoin, topical adapalene gel, topical 5-flououracil, topical calciptriol and tacalcitol (with sunscreen), grenz ray radiation, and x-ray radiation. All other evidence for treatments of DD consisted of case reports or case series, which is considered grade C evidence. Considering the quality and quantity of evidence, clinicians may consider initiating a trial of select topical or oral retinoids first in patients with localized or generalized DD, respectively.

Abstract
Abstract
Background
A history family of aortic dissection was considered as a risk factor for aortic dissection in patients with Marfan syndrome with a FBN1 mutation.
Objectives
Evaluate whether a family history of aortic dissection is a risk marker for dissection in this population
Methods
Retrospective study of patients coming to the reference centre between 1996 and 2018, carrying a FBN1 gene mutation. Pedigrees were obtained for each patient, and familial screening actively pursued. Patients with a family history of aortic dissection were compared with patients without family history of aortic dissection.
Results
1700 patients (age 33.2 (±17) years, 51% women) with a FBN1 gene mutation were included. 145 (8,5%) patients underwent aortic dissection at a mean age of 37.9 (±11.4) years and 323 (19%) patients had been operated at 33.8 (±13.9) years.
481 patients had a family history of aortic dissection, including 38 who dissected themselves, and 88 who underwent surgery. 1219 had no family history of aortic dissection, including 107 who dissected themselves, and 235 who underwent surgery.
Therefore, the personal risk for aortic dissection was similar in patients with and without a family history of aortic dissection (38/481, i.e. 7.9% vs 107/1219, i.e. 8.8%), as was the personal risk for prophylactic aortic surgery (88/481, i.e. 18.3% vs. 253/1219, i.e. 17.2%), and the risk for either aortic dissection or prophylactic aortic surgery (118/481, i.e. 24.5% vs. 328/1219, i.e. 26.9%).
Conclusions
In Marfan syndrome with a FBN1 gene mutation, a family history of aortic dissection is not a marker of aortic disease severity.

Abstract
Abstract
Background
Marfan syndrome (MFS) is a connective tissue disorder in which several systems are affected with great phenotypic variability. Although known to be associated with pathogenic variants in the FBN1 gene, few genotype-phenotype correlations have been found in probands' studies only.
Purpose
The aim of this study is to provide survival curves and genotype-phenotype correlations in all patients with FBN1 mutations, probands and relatives.
Methods
We established survival curves and sought genotype–phenotype correlations in a population of 1575 consecutive MFS patients with pathogenic class 4 or 5 variants in the FBN1 gene. This population represents the most comprehensive clinical database worldwide on MFS.
Results
Global survival was 90% at 60 years. However, lifelong aortic event rate (either dissection or surgery) and survival were impacted by the genotype. Premature termination codons (PTC), resulting in haploinsufficiency, were associated with a shorter life expectancy and a high lifelong risk of an aortic event (83%). Interestingly, these variants were also associated with the highest risk of severe scoliosis (52%) and with a lower risk for ectopia lentis (EL) surgery (13%). Dominant negative in-frame pathogenic variants could be subdivided according to their impact on the cysteine content of fibrillin-1: cysteine loss (–Cys) was associated with high aortic risk (73%) and a higher frequency of EL surgery (43%); cysteine addition was associated with moderate aortic risk (29%) and the highest frequency of EL surgery (48%); unchanged cysteine content was associated with high aortic risk (61%) and lower frequency of EL surgery (23%). No gene-region effect was observed, except for a more severe phenotype for in-frame variants with cysteine loss within the “neonatal region”. Aortic risk was greater for males in all subgroups, and probands were more severely affected.
Conclusions
MFS genotype-phenotype correlations related to pathogenic FBN1 variants exist for aortic and extra-aortic features. This leads us to propose new tools to refine the prognosis in this population. Preventive therapy with β-blockers and restricted exercise should be proposed regardless of the aortic diameter in the high aortic risk groups (PTC and –Cys variants). These results have major consequences on genetic counseling and personalized medicine for patients carrying a FBN1 mutation. This study also improves the overall understanding of the role of FBN1 in various organs.

Abstract
Abstract
Objectives
Routine postoperative blood tests (POBT) following robot assisted radical prostatectomy (RARP) are used to evaluate the impact of surgery on pre-existing co-morbidities and to detect early complications. This practice dates back to an era of open surgery, when blood loss and complication rates were higher. We propose new guidelines to improve the specificity of POBT.
Method
The cases of 1040 consecutive patients who underwent a primary or salvage RARP at two large tertiary urology centres in the United Kingdom were retrospectively reviewed to form new guidelines. The new guidelines were prospectively validated in a sample of 300 patients.
Results
Derivation Dataset: 3% and 5% had intra- and post-operative Clavien-Dindo complications, respectively. 15% had clinical concerns postoperatively. 0.9% required perioperative transfusion. 78% had routine blood tests without clinical concerns, none of whom developed a complication. 98% of complications were suspected by clinical judgement. 6% of patients had a discharge delay of ≥ 1 day due to delayed or incomplete blood tests. Validation Dataset: No significant difference existed in complication, clinical concern or transfusion rates between the derivation and validation datasets. Number of POBT requested reduced by 73% (p < 0.001). The new guidelines improved POBT sensitivity for complications from 98% to 100% and specificity from 0% to 74%. Discharge delays reduced from 6% to 0% (p = 0.008). Cost savings were £178 per patient.
Conclusions
Postoperative complications and transfusion following RARP are rare. Routine POBT without clinical indication are unnecessary and inefficient. A guideline-based approach to POBT can reduce costs and optimise discharge without compromising patient safety or care.

Abstract
Abstract
Introduction
High costs and inaccessibility are significant barriers to face-to-face basic surgical skills (BSS) training. Virtual classrooms enable the combination of computer-based learning with interactive expert instruction. They may optimise resources and increase accessibility, facilitating larger-scale training with a similar educational benefit. We aim to evaluate the efficacy of virtual BSS classroom training compared to both non-interactive video and face-to-face teaching.
Method
72 medical students will be randomly assigned to three equal intervention groups based on year group and surgical skill confidence. Interventions will be implemented following an instructional video. Group A will practice independently, Group B will receive face-to-face training, and Group C will attend a virtual classroom. Participants will be recorded placing three interrupted sutures with hand tied knots pre- and post-intervention, and Objective Structured Assessment of Technical Skills (OSATS) will be blind marked by two experts. Change in confidence, time to completion and a granular performance score will also be measured. Each intervention’s feasibility and accessibility will be assessed.
Results
Data collection will be completed in January 2021. Significant improvement in OSATS within groups will be indicative of intervention quality. Difference in improvement between groups will determine the relative performance of the interventions.
Conclusions
To our knowledge, this will be the largest randomised control trial investigating virtual BSS classroom training. It will serve as a comprehensive appraisal of the virtual classroom’s suitability as an alternative to face-to-face training. The findings will assist the development and implementation of further resource-efficient training programs during the COVID-19 pandemic and in the future.

Abstract
PURPOSE Gleason grade (GG) on prostate biopsy is important for risk stratification and clinical decision making. Multiparametric MRI (mpMRI) improved detection of clinically significant disease and some studies suggest that MRI-fusion biopsy combined with systematic biopsy results in fewer upgrades on final surgical pathology. However, the downgrade rate is unclear and there is controversy in the literature. The objectives of this study are to assess the concordance of combination biopsy with final surgical pathology, and furthermore, to specifically determine downgrade rates. MATERIALS AND METHODS In our institutional mpMRI-ultrasound fusion biopsy database, 173 underwent targeted and systematic biopsy followed by radical prostatectomy (RP). GG on targeted, systematic and combination (targeted and systematic) biopsy were compared with GG on RP. Concordance rates between biopsy types were compared with the McNemar test. Proportion of GG upgrade or downgrade at the time of RP was also evaluated. RESULTS Surgical pathology was concordant with 44.5% of systematic biopsies, 46.8% of targeted biopsies, and 56.7% of combination biopsies. Combination biopsy significantly overestimated the final GG on RP compared to systematic biopsy (16.8% vs. 8.7% RR 1.93, 95% CI 1.36-2.75, P < 0.001). Downgrade rate from unfavorable to favorable intermediate-risk disease was 46.2%, and from high-risk to intermediate-risk disease was 45.1%. CONCLUSIONS Combination (targeted and systematic) biopsy is associated with the highest concordance rate between biopsy and RP pathology when compared with systematic or targeted biopsy alone. However, targeting MRI lesions and therefore the higher risk components, may at times overestimate the final surgical pathology which can result in overtreatment of what may truly be less aggressive disease.

Abstract
Abstract
Introduction
Patients undergoing RARP commonly require routine post-operative blood tests. This practice dates from an era of open surgery, with increased blood loss and complications. We aim to improve specificity of blood test requests with novel guidelines.
Method
1039 consecutive RARP patients at two tertiary urology centres in the UK were audited. Novel guidelines constructed based on risk stratified evidence from the initial audit were used to prospectively audit 133 patients.
Results
16% had clinical concerns post-operatively. 1% and 4% had an intra- and post-operative complication. Intra- or post-operative clinical judgement flagged post-operative complications in 99.9%. 80% had routine blood tests with no clinical concerns. 6% had delayed discharge due to delayed processing of blood tests. 0.9% received a peri-operative transfusion.
Re-Audit Novel guidelines reduced the number of blood tests requested from 100% to 36%. Specificity in diagnosing a complication improved from 0% to 67%. Discharge delays reduced from 6% to 0% and no post-operative complications were missed (sensitivity 100%).
Conclusions
Routine blood tests, without an indication, did not flag any additional post-operative complications. Blood transfusion is rare for RARP. Novel guidelines to request post-operative blood tests will reduce costs and discharge delays whilst maintaining appropriate patient safety and care.

Abstract
Abstract
Introduction
Marfan syndrome (MFS) is responsible for cardiovascular disorders such as aortic aneurism and mitral valve prolapse (MVP).
A malignant MVP phenotype combining clinical, electrical and morphological features has been described in symptomatic patients who have experienced sudden cardiac death or complex ventricular arrhythmias.
We have taken advantage of the high prevalence of MVP in MFS patient to study the clinical, electrical and echocardiographic abnormalities associated with MVP.
Purpose
The aim of this study is to describe the clinical, electrical and morphological cardiac abnormalities associated with MVP in a cohort of MFS patients with FBN1 mutations with a high prevalence of MVP and who did not suffer from severe ventricular arrhythmias.
Methods
All consecutive patients coming to the National Reference Center for Marfan syndrome were evaluated prospectively i.e. clinical examination, 12-lead electrocardiogram, standard transthoracic echocardiography study and molecular genetic screening.
Results
352 consecutive patients were included from April 2015 to October 2016 [250 FBN1 mutation carriers (MFS) and 102 healthy relatives (HR)]. None of the patients had a history of sudden cardiac death or complex ventricular arrhythmia.
MFS vs HR: MFS patients were younger (33 vs 41yo p<0.001) and 2/3 were women in both groups. In the MFS group, abnormal T waves repolarization in lateral leads were more common [172 MFS (70.2%) vs. 87 HR (86.14%) p<0,0012], as was MVP [38.37% vs 1.96%; p<0,0001], and diastolic hypertrophy of the basal segment of the inferolateral wall (thickness >11mm) [22.31% vs. 9.18%; p<0.0001].
In MFS, MVP affected either one valve (21.22%), or both (17.14%), and was not associated with electric abnormalities. However, diastolic basal inferolateral wall hypertrophy was associated with mitral valve prolapse (p<0,0001), QTc interval prolongation (p<0.0229), abnormal T waves repolarization in the inferior leads (p=0.004), and higher aortic Z-Score (p=0.274).
Conclusion
In MFS patients, the prevalence of MVP is high and no significant association between MVP and electrical abnormalities was found. In contrast, basal inferolateral wall hypertrophy is associated with MVP and repolarization disorders in inferior leads and QTc interval prolongation, i.e, electrocardiographic abnormalities described in malignant MVP.

Abstract
Abstract
Background
Mutations in TGFB3 cause Loeys-Dietz syndrome-5 (LDS5), an autosomal dominantly inherited connective tissue disorder. LDS5 is characterized by aortic aneurysms and dissections associated with systemic features mainly involving the ocular and skeletal systems. Precise delineation of LDS5 phenotype is difficult because of the small number of identified cases.
Purpose
The purpose of this study was to further define LDS5 with an emphasis on cardiologic features by describing the genotype and phenotype in an international cohort of patients.
Methods
We performed a retrospective cross-sectional multicentre study. Genetic testing was performed as a part of standard medical care. Clinical data were collected by means of an anonymized questionnaire, which was sent to the referent physicians.
Results
Ten (7 novel) TGFB3 mutations were identified in 31 patients (16 index patients). The mean age at last evaluation was 32 years (range 4–60 years). Aortic root dilatation, varices, and mitral valve insufficiency were the most common cardiovascular findings, reported in 28%, 22%, and 21% of patients, respectively. Higher incidences (40%, 29%, and 25%) of these findings were observed in the index patients. Four patients (8%) underwent aortic surgery, all after age 40. Abdominal aortic aneurysms were reported in 2/26 (8%) patients. Extra aortic artery disease included iliac artery aneurysm (one index patient) and tortuosity of the internal carotid and vertebral arteries (one index patient and one relative). The most frequently reported systemic features were high-arched palate, arachnodactyly, pes planus, pectus deformity, and joint hypermobility. Interestingly, we identified an homozygous TGFB3 mutation in a patient who presented with aortic dilatation at age 17, splenic torsion, severe myopia, cleft palate, and other skeletal features. Her heterozygous parents, brother, and sister displayed signs of the disease, but to a milder degree. To the best of our knowledge, this is the first identification of homozygous TGFB3 mutation.
Conclusions
Our data are in line with previous research, showing that aortic root dilatation is the main cardiovascular feature of LDS5. No deaths related to cardiovascular events were reported in any of the presented families. The cardiovascular phenotype of LDS5 appears to be milder compared to other vascular connective tissue disorder, such as Marfan syndrome, although our findings suggest that homozygosity is associated with a more severe and early-onset phenotype.

Abstract
93 Background: Multiparametric MRI is increasingly used in prostate cancer detection. Previous studies have shown that detection rate of clinically significant cancer is higher in MRI targeted biopsy than systematic biopsy. However, the concordance between the Gleason score on fusion biopsy and radical prostatectomy is less well known. The objective of this study is to look for predictors of histopathologic concordance between biopsy (fusion and systematic) and radical prostatectomy. Methods: We used an institutional database of men who underwent mpMRI-ultrasound fusion targeted and systematic biopsy followed by radical prostatectomy. Gleason score on targeted, systematic and combination (targeted + systematic) biopsy were compared with Gleason score on radical prostatectomy, and concordance was recorded. The McNemar test was used to compare concordance and upgrade rates. Predictors of concordance and upgrade such as age, prostate volume, PSA, PSA density, Gleason score on biopsy, number of targets reported on mpMRI, and PI-RADS score were evaluated with Fisher’s exact test and logistic regression. Results: Surgical pathology was concordant with 47.4% of systematic biopsies, 52.0% of targeted biopsies and 58.4% of combination biopsies. There was no significant difference in concordance rates between systematic and targeted biopsy (P = 0.37). However, combination biopsy was superior to both systematic (RR 1.23, 95% CI 1.08-1.40, P = 0.03) and targeted biopsy (RR 1.12, 95% CI 1.02 – 1.24, P = 0.03) in predicting concordance with surgical pathology. Risk of upgrade to a higher Gleason score on surgical pathology was significantly lower with combination biopsy compared to systematic (RR 0.57, 95% CI 0.46-0.69, P < 0.001) or targeted biopsy alone (RR 0.72, 95% CI 0.61-0.84, P = 0.001). Upgrade rates were 43.9% for systematic biopsy, 34.7% for targeted, and 24.9% for combination. Lastly, we found no significant predictors of concordance or upgrade. Conclusions: Combination biopsy is associated with the highest concordance rate between biopsy and radical prostatectomy when compared with systematic or targeted biopsy alone. Performing targeted biopsy alone will underestimate tumour aggressiveness on surgical pathology.

Abstract
BACKGROUND Fluid administration to increase stroke volume index (SVi) is a cornerstone of haemodynamic resuscitation. We assessed the accuracy of SVi variation during a calibrated abdominal compression manoeuvre (ΔSVi-CAC) to predict fluid responsiveness in children. METHODS Patients younger than 8 yr with acute circulatory failure, regardless of their ventilation status, were selected. SVi, calculated as the average of five velocity-time integrals multiplied by the left ventricular outflow tract surface area, was recorded at four different steps: baseline, after an abdominal compression with a calibrated pressure of 25 mm Hg, after return to baseline, and then after a volume expansion (VE) of 10 ml kg-1 lactated Ringer solution over 10 min. Patients were classified as responders if SVi variation after volume expansion (ΔSVi-VE) increased by at least 15%. RESULTS The 39 children included had a median [inter-quartile range (IQR)] age of 9 [5-31] months. Twenty patients were fluid responders and 19 were non-responders. ΔSVi-CAC correlated with ΔSVi-VE (r=0.829; P<0.001). The area under the receiver operating characteristic curve (ROCAUC) was 0.94 [95% confidence interval (CI), 0.85-0.99]. The best threshold for ΔSVi-CAC was 11% with a specificity of 95% [95% CI, 84-100] and a sensitivity of 75% [95% CI, 55-95]. ROCAUC of respiratory variation of IVC diameter (ΔIVC) was 0.53 [95% CI, 0.32-0.72]. CONCLUSION ΔSVi-CAC during abdominal compression was a reliable method to predict fluid responsiveness in children with acute circulatory failure regardless of their ventilation status.

Abstract
INTRODUCTION We aimed to assess the contemporary knowledge of human papillomavirus (HPV) and its association with penile cancer in a nationwide cohort from the U.S. METHODS We used the Health Information National Trends Survey (HINTS), a cross-sectional telephone survey performed in the U.S. initiated by the National Cancer Institute. The most recent iteration, HINTS 4 Cycle 4, was conducted in mail format between August 19 and November 17, 2014. Primary endpoints included knowledge of HPV and its causal relationship to penile cancer. Baseline characteristics included sex, age, education, race and ethnicity, income, residency, personal or family history of cancer, health insurance status, and internet use. Multivariable logistic regression assessed predictors of HPV and penile cancer knowledge. RESULTS An unweighted sample of 3376 respondents was extracted from the HINTS 4, Cycle 4. Whereas 64.4% of respondents had heard of HPV, only 29.5% of these were aware that it could cause penile cancer. Men were significantly less likely to have heard of HPV than women (odds ratio [OR] 0.32; 95% confidence interval [CI] 0.24-0.43). Older age; African-American, Asian, and "other race"; being married; from a lower education bracket; having a personal cancer history; and those without internet access were significantly less likely to have heard of HPV. None of our examined variables were independent predictors for the knowledge of the association of penile cancer and HPV. CONCLUSIONS Our analysis of a large, nationally representative survey demonstrates that the majority of the American public is familiar with HPV, but lack a meaningful understanding between this virus and penile cancer. Primary care providers and specialists should be encouraged to intensify counselling about this significant association as a primary preventive measure of this potentially fatal disease.

Abstract
CONTEXT Testicular germ-cell tumors (GCT) are highly curable. A multidisciplinary approach, including cisplatin-based chemotherapy has resulted in cure in the majority of patients with GCT. Thus, the life expectancy of survivors will extend to many decades post-diagnosis. Late treatment toxicities associated with cisplatin-based chemotherapy may impact their future health. OBJECTIVE To systematically evaluate evidence regarding the long-term toxicity of cisplatin in GCT survivors. EVIDENCE ACQUISITION We carried out a critical review of PubMed/Medline in February 2017 according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement. Identified reports were reviewed according to the Consolidated Standards of Reporting Trials (CONSORT) criteria. Eighty-three publications were selected for inclusion in this analysis. EVIDENCE SYNTHESIS Included reports evaluated long-term toxicities of cisplatin-based chemotherapy in GCT survivors. Studies reporting neuro- and ototoxicity, secondary malignancies, cardiovascular, renal and pulmonary toxicities, hypogonadism and infertility were found. Seven studies (8%) reported genetic underpinnings of long-term toxicities and 3 (4%) and 14 (19%) studies correlated long-term toxicities with circulating platinum levels and cumulative dose of cisplatin, respectively. Significant risks for long-term toxicities associated with cisplatin and platinum-based regimens were reported. The cumulative dose of cisplatin and circulating platinum were reported as risk factors. Several single-nucleotide polymorphisms identified patients susceptible to cisplatin compared with wild-type individuals. CONCLUSIONS GCT survivors cured with cisplatin-based chemotherapy are at risk for long-term side-effects. Detection of single-nucleotide polymorphisms could be a valuable tool for predicting long-term toxicities. PATIENT SUMMARY Herein, this article summarizes the available evidence of long-term toxicity of cisplatin-based chemotherapy in GCT survivors and provide insights from Indiana University.

Abstract
e16506 Background: Use of androgen deprivation therapy (ADT) may confer a higher risk of cognitive impairment. Published results are variable and lack consensus. Our objective was to perform meta-analysis of the risk of overall cognitive impairment in men receiving ADT for prostate cancer. Methods: Relevant studies were identified through the search of English language articles indexed in PubMed Medline, PsycINFO, Cochrane Library and Web of Knowledge/Science until December 21st2016. Articles were included if they were published in English, reported on original research with adult male subjects undergoing treatment for prostate cancer, incorporated longitudinal comparisons, and included a control group. Controlled intervention studies were required to assess an established cognitive-related endpoint that was measured by a validated instrument, and measure cognitive impairment based on the International Cognition and Cancer Task Force (ICCTF) criteria. The effect of ADT on cognitive impairment was pooled using a random-effects model for controlled intervention and case-control studies separately. Results: Of 221 abstracts, 25 were selected for full-text review, and 8 studies, with 2 controlled studies and 6 case-control studies were identified. Overall cognitive impairment was not significantly different when the results of the 2 prospective studies were pooled (OR: 1.57, 95% CI: 0.50–4.92, P= 0.44), with significant heterogeneity between estimates ( I2: 83%). In retrospective data, the odds of developing any cognitive impairment were significantly higher in men treated with ADT (HR: 1.37, 95% CI: 1.06–1.77, P= 0.02), with considerable heterogeneity ( I2: 84%). Conclusions: The relationship between overall cognitive impairment and use of ADT defined according to the ICCTF criteria in a pooled-analysis of two prospective studies was inconclusive. Although retrospective studies suggest a higher risk of overall cognitive impairment after ADT, we caution readers not to over-interpret this finding given the limitations of retrospective data. Better well-designed prospective studies are needed to assess the effect of ADT on cognitive impairment with long-term follow-up.

Abstract
Purpose There is limited evidence to support the use of adjuvant chemotherapy (AC) after radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC). Against this backdrop, we hypothesized that such treatment is associated with overall survival (OS) benefit in patients with locally advanced and/or positive regional lymph node disease. Patients and Methods Within the National Cancer Database (2004 to 2012), we identified 3,253 individuals who received AC or observation after RNU for pT3/T4 and/or pN+ UTUC. Inverse probability of treatment weighting (IPTW) –adjusted Kaplan-Meier curves and Cox proportional hazards regression analyses were used to compare OS of patients in the two treatment groups. In addition, we performed exploratory analyses of treatment effect according to age, gender, Charlson comorbidity index, pathologic stage (pT3/T4N0, pT3/T4Nx and pTanyN+), and surgical margin status. Results Overall, 762 (23.42%) and 2,491 (76.58%) patients with pT3/T4 and/or pN+ UTUC received AC and observation, respectively, after RNU. IPTW-adjusted Kaplan-Meier curves showed that median OS was significantly longer for AC versus observation (47.41 [interquartile range,19.88 to 112.39] v 35.78 [interquartile range, 14.09 to 99.22] months; P < .001). The 5-year IPTW-adjusted rates of OS for AC versus observation were 43.90% and 35.85%, respectively. In IPTW-adjusted Cox proportional hazards regression analysis, AC was associated with a significant OS benefit (hazard ratio, 0.77 [95% CI, 0.68 to 0.88]; P < .001). This benefit was consistent across all subgroups examined (all P < .05), and no significant heterogeneity of treatment effect was observed (all Pinteraction > .05). Conclusion We report an OS benefit in patients who received AC versus observation after RNU for pT3/T4 and/or pN+ UTUC. Although our results are limited by the usual biases related to the observational study design, we believe that the present findings should be considered when advising post-RNU management of advanced UTUC, pending level I evidence.

Abstract
305 Background: There is limited evidence supporting the use of adjuvant chemotherapy (AC) after radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC). Against this backdrop, we hypothesized that such treatment is associated with an overall survival (OS) benefit in patients with locally advanced and/or positive regional lymph node disease. Methods: Within the National Cancer Data Base (2004-2012), we identified 3,253 individuals who received AC or observation after RNU for pT3/T4 and/or pN+ UTUC. Inverse probability of treatment weighting (IPTW)-adjusted Kaplan-Meier curves and Cox regression analyses were used to compare OS of patients in the two treatment groups. Additionally, we performed exploratory analyses of treatment effect according to age, gender, Charlson comorbidity index, pathological stage (pT3/T4N0, pT3/T4Nx and pTanyN+) and surgical margin status. Results: Overall, 762 (23.42%) and 2,491 (76.58%) patients with pT3/T4 and/or pN+ UTUC received AC and observation after RNU, respectively. IPTW-adjusted Kaplan-Meier curves showed that median OS was significantly longer for AC vs. observation (47.41 [IQR, 19.88-112.39] vs. 35.78 [IQR, 14.09-99.22] months; P< 0.001). The 5-year IPTW-adjusted rates of OS for AC vs. observation were 43.90% vs. 35.85%, respectively. In IPTW-adjusted Cox regression analysis, AC was associated with a significant OS benefit (HR = 0.77; 95% CI = [0.68-0.88]; P< 0.001). This benefit was consistent across all subgroups examined (all P< 0.05) and no significant heterogeneity of treatment effect was observed (all Pinteraction> 0.05). The 3-month conditional landmark IPTW-adjusted analysis demonstrated little impact of immortal time bias (HR = 0.79; 95% CI = [0.70-0.91]; P = 0.001). Conclusions: We report an OS benefit in patients who received AC vs. observation after RNU for pT3/T4 and/or pN+ UTUC. Although our results are limited by the usual biases related to the observational study design, we believe that the present findings should be considered when advising post-RNU management of advanced UTUC, pending level I evidence.
