Objectives To assess the utility of genomic testing in risk-stratifying Black patients with low and intermediate risk prostate cancer. Methods We retrospectively identified 63 Black men deemed eligible for active surveillance based on National Comprehensive Cancer Network® (NCCN) guidelines, who underwent OncotypeDx® Genomic Prostate Score™ testing between April 2016 and July 2020. Nonparametric statistical testing was used to compare relevant features between patients reclassified to a higher NCCN risk after genomic testing and those who were not reclassified. Results The median age was 66 years and median pre-biopsy PSA was 7.3. Initial risk classifications were: very low risk: seven(11.1%), low risk: 24(38.1%), favorable intermediate risk: 31(49.2%), and unfavorable intermediate risk: one(1.6%). Overall, NCCN risk classifications after Genomic Prostate Score testing were significantly higher than initial classifications (p=0.003, Wilcoxon signed-rank). Among patients with discordant risk designations, 28(28/40, 70%) were reclassified to a higher NCCN risk after genomic testing. A pre-biopsy prostate specific antigen of greater than 10 did not have significantly higher odds of HBR (OR:2.16 [95% CI: 0.64,7.59, p=0.2). Of favorable intermediate risk patients, 20(64.5%) were reclassified to a higher NCCN risk. Ultimately, 18 patients underwent definitive treatment. Conclusions Incorporation of genomic testing in risk stratifying Black men with low and intermediate-risk prostate cancer resulted in overall higher NCCN risk classifications. Our findings suggest a role for increased utilization of genomic testing in refining risk-stratification within this patient population. These tests may better inform treatment decisions on an individualized basis.

There are limited data regarding the effect of treatment delays on important long-term outcomes among men with intermediate/high-risk prostate cancer (PC).We identified 3,962 men with intermediate/high-risk disease from the SEARCH cohort treated with radical prostatectomy (RP) from 1988 to 2018. Cox proportional hazard models assessed the association between time from biopsy to RP (up to 1 year) and time to castration-resistant PC (CRPC), metastasis and all-cause mortality. Interaction terms were used to test for effect modification by risk group.Of the 3,962 men, 167 developed CRPC, 248 developed metastases and 884 died after a median followup of 85 months. Longer delays between biopsy and RP were associated with a decreased risk of CRPC (adjusted HR=0.88, 95% CI: 0.80-0.98, p=0.02), independent of D'Amico risk group (interaction p0.05). In men with intermediate and high-risk disease, we found no statistically significant association between length of time to RP and risk of developing metastases (p=0.5 and 0.9, respectively) or all-cause mortality (p=0.1 and 0.1, respectively).Among men with intermediate and high-risk PC, we found no statistically significant increased risk of adverse long-term outcomes, including CRPC, metastasis and death, for men who had treatment delays up to 1 year following PC diagnosis.

To evaluate our institutional outcomes utilizing Cs-131 prostate brachytherapy (PB) for the intermediate-risk (IR) group of prostate cancer patients.We reviewed a prospectively collected database of men treated with Cs-131 PB between 2006 and 2019. Patients with less than 24-months follow-up were excluded. Patients were classified as IR if they had one of the following factors: Gleason Score 7, prostate specific antigen10 but20 ng/mL, or T2b-c on clinical exam. We defined unfavorable-IR (UIR) as having either Grade Group 3,1 IR factors, or ≥50% positive core biopsies. The Kaplan-Meier method was used to estimate actuarial event-time probabilities for biochemical freedom from disease (BFD).A total of 335 patients with a median follow-up of 70.1 months (IQR 48.3-106.3 months) were identified. Androgen deprivation therapy (ADT) was used in 7.2% of patients. Favorable-IR (FIR) patients were commonly treated with PB alone (91.8%). FIR patients who underwent PB alone had a 5-year BFD of 98.1%. UIR patients were commonly treated with external beam radiotherapy plus PB (61.2%). These patients had 5-year BFD of 91.1%. The 5-year BFD for UIR patients treated without ADT was 90.9%, whereas it was 95.0% among UIR patients treated with ADT (log-rank p = 0.83).FIR patients have excellent outcomes when treated with PB alone. External beam radiotherapy plus PB is a reasonable treatment approach for UIR patients. Future studies may elucidate which IR patients would benefit from treatment intensification.

Pooled cohort equations (PCEs) estimate 10-year risk for atherosclerotic cardiovascular disease (ASCVD) in US adults. One use is to guide statin eligibility. However, PCEs risk estimate is inaccurate in some US subpopulations.Recent cholesterol guidelines proposed addition of risk enhancing factors to improve risk assessment for selection of statin therapy. This study examines frequencies of several risk enhancing biomarkers in NHANES subjects at intermediate risk (7.5 -20% 10-year risk for ASCVD) and considers how they may be used to better assess risk for individuals.Prevalence of the following biomarkers were determined; elevations in apolipoprotein B-containing lipoproteins, i.e., LDL cholesterol (LDL-C) (160-189 mg/dL), non-HDL-cholesterol (non-HDL-C) (190-219 mg/dL), or total apolipoprotein B (apoB) (≥ 130 mg/dL), serum triglyceride (≥175 mg/dL), hemoglobin A1c (5.7-6.4%), high sensitivity C-reactive protein (2-10 mg/L), and waist circumference ≥ 102 cm, and abnormal estimated glomerular filtration rate (15 - ≤ 60 mg/min/1.73 m25% of NHANES population had intermediate risk. In this subpopulation, 85% had ≥ 1 biomarkers-similarly in women and men-with a third having ≥3 abnormal markers. Frequencies were not age-related, except in those 40-49 years, in whom40% had ≥3 abnormal biomarkers. It made little difference whether LDL-C, non-HDL-C or apoB was used as the atherogenic lipoprotein.Three or more enhancing risk factors in intermediate risk subjects can complement PCE-estimated 10-year risk and guide the patient-provider discussion toward use of lipid-lowering medication. Future research is needed to integrate risk estimates by PCE and multiple risk enhancers.

Among the recently described subtypes in childhood B-lymphoblastic leukemia (B-ALL) were DUX4- and PAX5-altered (PAX5alt). By using whole transcriptome RNA sequencing in 377 children with B-ALL from the Malaysia-Singapore ALL 2003 (MS2003) and Malaysia-Singapore ALL 2010 (MS2010) studies, we found that, after hyperdiploid and ETV6-RUNX1, the third and fourth most common subtypes were DUX4 (n = 51; 14%) and PAX5alt (n = 36; 10%). DUX4 also formed the largest genetic subtype among patients with poor day-33 minimal residual disease (MRD; n = 12 of 44). But despite the poor MRD, outcome of DUX4 B-ALL was excellent (5-year cumulative risk of relapse [CIR], 8.9%; 95% confidence interval [CI], 2.8%-19.5% and 5-year overall survival, 97.8%; 95% CI, 85.3%-99.7%). In MS2003, 21% of patients with DUX4 B-ALL had poor peripheral blood response to prednisolone at day 8, higher than other subtypes (8%; P = .03). In MS2010, with vincristine at day 1, no day-8 poor peripheral blood response was observed in the DUX4 subtype (P = .03). The PAX5alt group had an intermediate risk of relapse (5-year CIR, 18.1%) but when IKZF1 was not deleted, outcome was excellent with no relapse among 23 patients. Compared with MS2003, outcome of PAX5alt B-ALL with IKZF1 codeletion was improved by treatment intensification in MS2010 (5-year CIR, 80.0% vs 0%; P = .05). In conclusion, despite its poor initial response, DUX4 B-ALL had a favorable overall outcome, and the prognosis of PAX5alt was strongly dependent on IKZF1 codeletion.

PURPOSE A group of international urology and medical oncology experts developed and completed a survey on prostate cancer (PCa) in developing countries. The results are reviewed and summarized, and recommendations on consensus statements for very low-, low-, and intermediate-risk PCa focused on developing countries were developed. METHODS A panel of experts developed more than 300 survey questions of which 66 questions concern the principal areas of interest of this paper: very low, low, and intermediate risk of PCa in developing countries. A larger panel of 99 international multidisciplinary cancer experts voted on these questions to create the recommendations for treatment and follow-up for very low-, low-, and intermediate-risk PCa in areas of limited resources discussed in this manuscript. RESULTS The panel voted publicly but anonymously on the predefined questions. Each question was deemed consensus if 75% or more of the full panel had selected a particular answer. These answers are based on panelist opinion not a literature review or meta-analysis. For questions that refer to an area of limited resources, the recommendations consider cost-effectiveness and the possible therapies with easier and greater access. Each question had five to seven relevant answers including two nonanswers. The results were tabulated in real time. CONCLUSION The voting results and recommendations presented in this document can be used by physicians to support management for very low, low, and intermediate risk of PCa in areas of limited resources. Individual clinical decision making should be supported by available data; however, as guidelines for treatment for very low, low, and intermediate risk of PCa in developing countries have not been developed, this document will serve as a point of reference when confronted with this disease.

Background Active surveillance is an alternative to radical treatment for patients with low-risk prostate cancer, which could also benefit some patients with intermediate risk. We have investigated the use of miRNA in urinary extracellular vesicles to stratify these patients. Methods NGS was performed to profile the miRNAs from small urinary extracellular vesicles in a cohort of 70 patients with prostate cancer ISUP Grade 1, 2 or 3. The most promising candidates were then analysed by RT-qPCR in a new cohort of 60 patients. Results NGS analysis identified nine miRNAs differentially expressed in at least one of the comparisons. The largest differences were found with miR-1290 (Grade 3 vs. 1), miR-320a-3p (Grade 3 vs. 2) and miR-155-5p (Grade 2 vs. 1). Combinations of 2–3 miRNAs were able to differentiate between two ISUP grades with an AUC 0.79–0.88. RT-qPCR analysis showed a similar trend for miR-186-5p and miR-30e-5p to separate Grade 3 from 2, and miR-320a-3p to separate Grade 2 from 1. Conclusions Using NGS, we have identified several miRNAs that discriminate between prostate cancer patients with ISUP Grades 1, 2 and 3. Moreover, miR-186-5p, miR-320a-3p and miR-30e-5p showed a similar behaviour in an independent cohort using an alternative analytical method. Our results show that miRNAs from urinary vesicles can be potentially useful as liquid biopsies for active surveillance.

Race/ethnicity may predispose to less favorable prostate cancer characteristics in intermediate risk prostate cancer (IR PCa) patients. We tested this hypothesis in a subgroup of IR PCa patients treated with radical prostatectomy (RP). We relied on the Surveillance, Epidemiology and End Results 2004–2016. The effect of race/ethnicity was tested in univariable and multivariable logistic regression analyses predicting upstaging (pT3+/pN1) and/or upgrading (Gleason Grade Group [GGG] 4–5) at RP. Of 20,391 IR PCa patients, 15,050 (73.8%) were Caucasian, 2857 (14.0%) African-American, 1632 (8.0%) Hispanic/Latino and 852 (4.2%) Asian. Asian patients exhibited highest age (64 year), highest PSA (6.8 ng/ml) and highest rate of GGG3 (31.9%). African-Americans exhibited the highest percentage of positive cores at biopsy (41.7%) and the highest proportion of NCCN unfavorable risk group membership (54.6%). Conversely, Caucasians exhibited the highest proportion of cT2 stage (35.6%). In univariable analyses, Hispanic/Latinos exhibited the highest rates of upstaging/upgrading among all race/ethnicities, in both favorable and unfavorable groups, followed by Asians, Caucasians and African-Americans in that order. In multivariable analyses, Hispanic/Latino race/ethnicity represented an independent predictor of higher upstaging and/or upgrading in favorable IR PCa (odds ratio [OR] 1.27, p

Data from 1661 consecutive subjects with chronic-phase chronic myeloid leukemia (CML) receiving initial imatinib (n = 1379) or a 2nd-generation tyrosine-kinase inhibitor (2G-TKI; n = 282) were interrogated to determine whether the Sokal or European Treatment and Outcome Study for CML (EUTOS) long-term survival (ELTS) scores were more accurate responses and outcome predictors. Both scores predicted probabilities of achieving complete cytogenetic response (CCyR), major molecular response (MMR), failure- and progression-free survivals (FFS, PFS), and survival in all subjects and those receiving imatinib therapy. However, the ELTS score was a better predictor of MR4, MR4.5, and CML-related survival than the Sokal score. In subjects receiving 2G-TKI therapy, only the ELTS score accurately predicted probabilities of CCyR, MMR, MR4, FFS, and PFS. In the propensity score matching, subjects classified as intermediate risk by the ELTS score receiving a 2G-TKI had better responses (p p = 0.002), and PFS (p = 0.03) but not survival. Our data suggest better overall prediction accuracy for the ELTS score compared with the Sokal score in CML patients, especially those receiving 2G-TKIs. People identified as intermediate risk by the ELTS score may benefit more from initial 2G-TKI therapy in achieving surrogate endpoints but not survival, especially when a briefer interval to stopping TKI therapy is the therapy objective.

Purpose This study’s objective was the comparison of external beam radiotherapy (EBRT) and I‑125 seed brachytherapy regarding clinical outcome and development of side effects. Patients and methods In all, 462 localized intermediate-risk prostate cancer patients treated between 2000 and 2019 at our department using either I‑125 seed brachytherapy or EBRT with a dose of 74 or 78 Gy were included: 297 patients were treated with EBRT and 165 with seeds. Biochemical no evidence of disease (bNED) rates according to Phoenix definition as well as late gastrointestinal and urogenital side effects (EORTC/RTOG) were assessed. Results Patients were followed up yearly with a median follow-up of 54 (3–192) months. Observed bNED rates for 74 Gy, 78 Gy and seeds were 87, 92, and 88% after 5 years and 71, 85, and 76% after 9 years, respectively. No significant differences were found comparing seeds with 74 Gy (p = 0.81) and 78 Gy (p = 0.19), as well as between 74 and 78 Gy (p = 0.32). Concerning gastrointestinal side effects, EBRT showed significantly higher rates of RTOG grade ≥ 2 toxicity compared to seeds, but at no point of the follow-up more than 10% of all patients. However, genitourinary side effects were significantly more prevalent in patients treated with seeds, with 33% RTOG grade ≥ 2 toxicity 12 months after treatment. Nevertheless, both types of side effects decreased over time. Conclusion Favorable intermediate-risk prostate cancer patients can be treated either by external beam radiotherapy (74/78 Gy) or permanent interstitial seed brachytherapy.

PURPOSE: Temporary COVID-19 guideline recommendations have recently been issued to expand the use of colony-stimulating factors in patients with cancer with intermediate to high risk for febrile neutropenia (FN). We evaluated the cost-effectiveness of primary prophylaxis (PP) with biosimilar filgrastim-sndz in patients with intermediate risk of FN compared with secondary prophylaxis (SP) over three different cancer types. METHODS: A Markov decision analytic model was constructed from the US payer perspective over a lifetime horizon to evaluate PP versus SP in patients with breast cancer, non–small-cell lung cancer (NSCLC), and non-Hodgkin lymphoma (NHL). Cost-effectiveness was evaluated over a range of willingness-to-pay thresholds for incremental cost per FN avoided, life year gained, and quality-adjusted life year (QALY) gained. Sensitivity analyses evaluated uncertainty. RESULTS: Compared with SP, PP provided an additional 0.102-0.144 LYs and 0.065-0.130 QALYs. The incremental cost-effectiveness ranged from $5,660 in US dollars (USD) to $20,806 USD per FN event avoided, $5,123 to $31,077 USD per life year gained, and $7,213 to $35,563 USD per QALY gained. Over 1,000 iterations, there were 73.6%, 99.4%, and 91.8% probabilities that PP was cost-effective at a willingness to pay of $50,000 USD per QALY gained for breast cancer, NSCLC, and NHL, respectively. CONCLUSION: PP with a biosimilar filgrastim (specifically filgrastim-sndz) is cost-effective in patients with intermediate risk for FN receiving curative chemotherapy regimens for breast cancer, NSCLC, and NHL. Expanding the use of colony-stimulating factors for patients may be valuable in reducing unnecessary health care visits for patients with cancer at risk of complications because of COVID-19 and should be considered for the indefinite future.

Transcatheter aortic valve replacement (TAVR) has revolutionized the treatment of patients with severe aortic stenosis and is now standard of care for high surgical risk patients and a valid alternative strategy in intermediate risk patients. Recently, TAVR has shown excellent results in low-risk patients, indicating an imminent extension toward this population. Improvements in procedural outcomes are the result of increasing operator experience, sophisticated imaging for procedural planning but also due to the continuous evolution of transcatheter heart valves developed to minimize procedural complications. ‘Next-generation’ valves are currently available, among them the self-expanding ACURATE neo. Here, the technical details and clinical outcomes of the ACURATE neo are reviewed, comparative data with other ‘next-generation’ valves and potential advantages and disadvantages are discussed.

Multiparametric assays for risk stratification are widely used in the management of both node negative and node positive hormone receptor positive invasive breast cancer. Recent data from multiple sources suggests that different tests may provide different risk estimates at the individual patient level. The TEAM pathology study consists of 3284 postmenopausal ER+ve breast cancers treated with endocrine therapy Using genes comprising the following multi-parametric tests OncotypeDx®, Prosigna™ and MammaPrint® signatures were trained to recapitulate true assay results. Patients were then classified into risk groups and survival assessed. Whilst likelihood χ2 ratios suggested limited value for combining tests, Kaplan–Meier and LogRank tests within risk groups suggested combinations of tests provided statistically significant stratification of potential clinical value. Paradoxically whilst Prosigna-trained results stratified Oncotype-trained subgroups across low and intermediate risk categories, only intermediate risk Prosigna-trained cases were further stratified by Oncotype-trained results. Both Oncotype-trained and Prosigna-trained results further stratified MammaPrint-trained low risk cases, and MammaPrint-trained results also stratified Oncotype-trained low and intermediate risk groups but not Prosigna-trained results. Comparisons between existing multiparametric tests are challenging, and evidence on discordance between tests in risk stratification presents further dilemmas. Detailed analysis of the TEAM pathology study suggests a complex inter-relationship between test results in the same patient cohorts which requires careful evaluation regarding test utility. Further prognostic improvement appears both desirable and achievable.

Purpose We performed a systematic review and a meta-analysis to investigate the successful ablation rate after radioiodine (RAI) administration in patients with differentiated thyroid cancer (DTC) at intermediate-high risk of recurrence. Methods A comprehensive literature search of the PubMed, Scopus, and Web of Science databases was conducted according to the PRISMA statement. Results The final analysis included 9 studies accounting for 3103 patients at intermediate-high risk of recurrence. In these patients, the successful ablation rates ranged from 51 to 94% with a 71% pooled successful ablation and were higher in intermediate (72%) than in high (52%)-risk patients. Despite the rigorous inclusion standards, a significant heterogeneity among the evaluated studies was observed. Higher administered RAI activities are associated with a lower successful ablation rate in the whole population and in the subgroup of high-risk patients. Furthermore, pooled recurrence rate in intermediate-risk patients achieving successful ablation was only 2% during the subsequent 6.4-year follow-up while the pooled recurrence rate was 14% in patients who did not achieve a successful ablation. Conclusion In a large sample of 3103 patients at intermediate-high risk of persistent/recurrent disease, 71% of patients achieved a successful ablation. In these intermediate-risk patients, the probability of subsequent recurrence is low and most recurrence occurred in those with already abnormal findings at the first control.

The comparative mid and long-term durability, including the rates of bioprosthetic valve failure (BVF) of the Sapien XTConsecutive intermediate-risk patients with severe aortic stenosis from the Mexican registry of transcatheter aortic valve replacement (TAVR) with SapienDuring 2014-2019, 115 (60 Sapien XTThe BVF rate at 25 months of follow-up was similar with the XT and S3 systems. During this follow-up period, the major composite events of death from any cause and neurological events were significantly lower with the S3 system.

BackgroundRisk stratification plays an essential role in the management of patients with pulmonary arterial hypertension (PAH). The current European guidelines propose a three-stratum model to categorise risk as low, intermediate or high, based on the expected 1-year mortality. However, with this model, most patients are categorised as intermediate risk. We investigated a modified approach based on four risk categories, with intermediate risk subdivided into intermediate-low and intermediate-high risk.MethodsWe analysed data from the Comparative, Prospective Registry of Newly Initiated Therapies for Pulmonary Hypertension (COMPERA), a European pulmonary hypertension registry, and calculated risk at diagnosis and first follow-up based on World Health Organization functional class, 6-min walk distance (6MWD) and serum levels of brain natriuretic peptide (BNP) or N-terminal pro-BNP (NT-proBNP), using refined cut-off values. Survival was assessed using Kaplan–Meier analyses, log-rank testing and Cox proportional hazards models.ResultsData from 1655 patients with PAH were analysed. Using the three-stratum model, most patients were classified as intermediate risk (76.0% at baseline and 63.9% at first follow-up). The refined four-stratum risk model yielded a more nuanced separation and predicted long-term survival, especially at follow-up assessment. Changes in risk from baseline to follow-up were observed in 31.1% of the patients with the three-stratum model and in 49.2% with the four-stratum model. These changes, including those between the intermediate-low and intermediate-high strata, were associated with changes in long-term mortality risk.ConclusionsModified risk stratification using a four-stratum model based on refined cut-off levels for functional class, 6MWD and BNP/NT-proBNP was more sensitive to prognostically relevant changes in risk than the original three-stratum model.

Cardiovascular diseases (CVD) represent a major cause of mortality and morbidity worldwide. To date, many physicians still requesting traditional lipid profile tests (TG, TC, HDL-C, and LDL-C) to confirm the clinical diagnosis related to CVD. However, using these tests may be inadequate for the prediction of CVD risk, especially in intermediate risk. For better clinical practice, laboratory diagnostic alternatives should constantly be evaluated and developed by physicians and laboratory scientists. In this review, we sought to focus on the benefits of lipid ratios (CRI-, CRI-II, AIP, AC, and CHOLindex) in supporting clinical diagnosis and how they can be calculated. To attain this aim, a literature search in reputed databases (PubMed and Scopus) was performed and peer-reviewed research articles were included to conduct this review. Short theoretical and practical notes about each index were accordingly included along with calculation formulas. Thus, the current article can assist new researchers and young physicians to review what supports their knowledge in managing early CVDs.

Objective:This study aims to explore the association between alpha methylacyl A coenzyme racemase (AMACR)/P504S staining intensity of prostate biopsy cores and five-year biochemical recurrence after radical prostatectomy in patients diagnosed with localised prostate cancer.Materials and Methods:Patients who underwent radical prostatectomy for organ-limited prostate cancer were retrospectively examined. Twenty-five patients without recurrence after definitive treatment and 25 patients with prostate-specific antigen (PSA) recurrence at postoperative follow-up were classified as group 1 and group 2. Positive prostate biopsy cores of patients were stained with AMACR/P504S, prospectively. Staining intensities were scored as negative (score=0), weak (score=1), moderate (score=2) and strong (score=3). Groups were compared regarding AMACR/P504S staining intensities of biopsy cores.Results:The mean AMACR/P504S staining scores of positive biopsy cores were 1.88±0.85 and 1.27±1.22 for group 1 and group 2. There was a statistically significant relationship between mean AMACR/P504S staining scores and PSA recurrence (p=0.002). AMACR score groups were not separated concerning biochemical recurrence endpoints in the Kaplan-Meier analysis (p=0.43).Conclusion:There is a significant relationship between increased AMACR/P504S expression in cancerous prostate tissue and PSA recurrence after radical prostatectomy.

Introduction There are several prognostic scores for the assessment of risk of atrial fibrillation (AF) recurrence post ablation procedure. However, the use of these complex scores is difficult and the validation on different populations brought divergent results. Our goal was to compare the performance of these risk scores as the basis for the development of a new, simplified score based only on few universally predictive variables. Methods All cryoballoon‐based AF ablations performed in a single‐center over a 10‐year period were prospectively analyzed with regard to AF recurrence. This served to analyze the performance of APPLE, CAAP‐AF, SCALE‐CryoAF, MB‐LATER, CHADS2, and CHA2DS2‐VASc risk scores. Results A total of 597 patients, mostly (78.1%) with paroxysmal AF were studied. Analyzed risk scores performed poorer than in the original publications because some risk factors were not predictive of AF recurrence. A simplified score named 0‐1‐2 PL, composed of just two universally predictive variables, AF type (1 point for P ersistent AF) and LA dimension (1 point for L A size >45 mm) was developed. The 0‐1‐2 PL score stratified patients into low risk (0 points), intermediate risk (1 point), and high risk categories (2 points) which were related to a 2‐year risk of AF recurrence of 21%, 37%, and 55%, respectively. This score had C‐statistics (0.620) higher/comparable to other investigated much more complex scores. Conclusion The assessment of risk of AF recurrence at the pre‐ablation stage can be simplified without compromising accuracy. This could help to popularize risk assessment and standardization of AF management., This study suggests that despite the significant differences between risk scores in terms of the choice of risk factors and the relative weights assigned to them, their performance for pre‐ablation risk assessment is quite similar, and weaker than originally reported. It seems that the assessment of the risk of AF recurrence at the pre‐ablation stage can be simplified by using the novel 0‐1‐2 PL score instead of more complex scores.

Background The widespread clinical application of coronary cardiovascular magnetic resonance (CMR) angiography (CMRA) for the assessment of coronary artery disease (CAD) remains limited due to low scan efficiency leading to prolonged and unpredictable acquisition times; low spatial-resolution; and residual respiratory motion artefacts resulting in limited image quality. To overcome these limitations, we have integrated highly undersampled acquisitions with image-based navigators and non-rigid motion correction to enable high resolution (sub-1 mm3) free-breathing, contrast-free 3D whole-heart coronary CMRA with 100% respiratory scan efficiency in a clinically feasible and predictable acquisition time. Objectives To evaluate the diagnostic performance of this coronary CMRA framework against coronary computed tomography angiography (CTA) in patients with suspected CAD. Methods Consecutive patients (n = 50) with suspected CAD were examined on a 1.5T CMR scanner. We compared the diagnostic accuracy of coronary CMRA against coronary CTA for detecting a ≥ 50% reduction in luminal diameter. Results The 50 recruited patients (55 ± 9 years, 33 male) completed coronary CMRA in 10.7 ± 1.4 min. Twelve (24%) had significant CAD on coronary CTA. Coronary CMRA obtained diagnostic image quality in 95% of all, 97% of proximal, 97% of middle and 90% of distal coronary segments. The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy were: per patient (100%, 74%, 55%, 100% and 80%), per vessel (81%, 88%, 46%, 97% and 88%) and per segment (76%, 95%, 44%, 99% and 94%) respectively. Conclusions The high diagnostic image quality and diagnostic performance of coronary CMRA compared against coronary CTA demonstrates the potential of coronary CMRA as a robust and safe non-invasive alternative for excluding significant disease in patients at low-intermediate risk of CAD.

PURPOSE: Active surveillance for patients with low and intermediate risk prostate cancers is becoming a more utilized option in recent years. However, the use of magnetic resonance imaging and imaging-targeted biopsy for monitoring grade progression has been poorly studied in this population. We aim to define the utility of magnetic resonance imaging-targeted biopsy and systematic biopsy in an active surveillance population. MATERIALS AND METHODS: Between July 2007 and January 2020, patients with diagnosed prostate cancer who elected active surveillance were monitored with prostate magnetic resonance imaging, imaging-targeted biopsy and standard systematic biopsy. Patients were eligible for surveillance if diagnosed with any volume Gleason grade 1 disease and select Gleason grade 2 disease. Grade progression (Gleason grade 1 to ≥2 disease and Gleason grade 2 to ≥3 disease) for each biopsy modality was measured at 2 years, 4 years and 6+ years. RESULTS: In total, 369 patients had both magnetic resonance imaging-targeted and systematic biopsy and were surveilled for at least 1 year. At 2 years, systematic biopsy, magnetic resonance imaging-targeted biopsy and combined biopsy (systematic+imaging-targeted) detected grade progression in 44 patients (15.9%), 73 patients (26.4%) and 90 patients (32.5%), respectively. Magnetic resonance imaging-targeted biopsy detected more cancer grade progression compared to systematic biopsy in both the low and intermediate risk populations (p

Ambulatory blood pressure monitoring (ABPM) is now considered the gold standard to evaluate BP, and predicts related cardiovascular risk. However, no study has reported the association of long-term changes in ABPM with the incidence of cardiovascular events, therefore the objective of this work. We included patients from the Bordeaux cohort of hypertensive patients, who had undergone at least two ABPM; the first was performed before or after antihypertensive treatment was started, and the second was the last recording available before any cardiovascular event. We included 591 patients (mean age, 54 years) with a 7-year average interval between the first and last ABPM, a 10-year average follow-up, and a total of 111 cardiovascular events. The patients were divided into four groups: G0, first and last 24 h systolic blood pressure (SBP)

The aim of this work was to evaluate the results of the use of cladribine in the treatment according to the AML-MM-2006 protocol as post-remission therapy in children. This study is supported by the Independent Ethics Committee and approved by the Academic Council of the Dmitry Rogachev National Medical Research Center of Pediatric Hematology, Oncology and Immunology. The article presents the experience of treating children with AML at the Russian Children's Clinical Hospital, and later at the Dmitry Rogachev National Research Center within the framework of the AML-MM-2006 protocol. For the period from 2006 to 2018, 25 children were included in the study. As a comparison, to assess the effectiveness of therapy, the remaining cohort of patients from the intermediate risk group, which consisted of 83 children, was selected. Ultimately, the addition of cladribine in consolidation therapy did not show a significant therapeutic effect (event-free survival 0.47 ± 0.1 for the cladribine group, 0.52 ± 0.06 for the control group), including the development of relapse (56% patients in the cladribine group had a relapse, in the control group – in 34.5%). Thus, the study proved that further inclusion of cladribine in consolidation therapy for primary AML is inappropriate.

Presentamos el caso de un paciente de 68 años, sin antecedentes de importancia, que por su cuadro clínico y resultados paraclínicos fue clasificado con riesgo intermedio para coledocolitiasis. En efecto, por medio de colangiorresonancia se realizó el diagnóstico confirmatorio. Fue llevado a colangiopancreatografía retrograda endoscópica en dos ocasiones –la primera fallida por papila intradiverticular–; en el segundo intento (exitoso con extracción del lito), el paciente presentó evolución posprocedimiento tórpida, con marcado dolor abdominal y anemización. Fue llevado a tomografía de abdomen con contraste, la cual confirmó el diagnóstico de hematoma subcapsular. Se decidió implementar el manejo conservador y se logró un control adecuado del sangrado.

Statins effectively reduce risk for atherosclerotic cardiovascular disease (ASCVD) when 10-year risk is ≥ 7.5%. In many patients at intermediate risk (7.5-20% risk), there is uncertainty about reliability of risk assessment by current pooled cohort equations (PCE). A decision to initiate statin therapy is favored by several risk enhancing factors not employed in PCEs.This study examines the scope of the metabolic syndrome, a risk enhancing factor, and its principal sequala, diabetes, in 26,796 US adults age 40-75 years from the NHANES survey data, 1999-2016.The prevalence of metabolic syndrome without diabetes (MetS+) and of diabetes (DM+) were determined for 10-year risk categories estimated to be low (7.5%), intermediate (7.5% -20%) and high (≥20%). Data were weighted to account for complex study design.90.4% of the population was free of ASCVD. In subjects projected to be at low risk by PCEs, MetS+ was present in 15.0% and 17.6% of women and men, respectively. MetS + increased to 30.6% of women and 29.6% of men at intermediate risk, and to 21.5% of women and 32.2% of men at high risk. In addition, DM+ was present in 6.1%/5.3% (F/M) of low risk individuals, 20.1%/14.8% (F/M) of intermediate risk subjects, and 44.3%/39.4% (F/M) of high-risk persons. Prevalence of both MetS+ and DM + rose progressively with age in women and men.MetS+ and DM + are common multiplex risk factors that predispose to higher lifetime risk and support statin therapy in patients at intermediate and high risk.

Objective We aimed to evaluate the impact of the sentinel lymph node (SLN) biopsy on adjuvant therapy, recurrence and survival in early endometrial cancer (EC). Study design We retrospectively included all patients who underwent SLN biopsy for EC between February 2007 and March 2018. Results Of the 249 EC patients included, the overall SLN detection rate was 91 %. SLNs were positive in 36 (14.4 %) cases. Nine of the 13 preoperative low-risk patients with positive SLNs were re-operated and 22 % presented positive non-SLNs. No second surgery was required for the 10 patients upstaged to intermediate risk after negative SLN biopsy. Nine of the 11 preoperative intermediate-risk patients with positive SLNs were re-operated and 33 % presented positive non-SLNs. Eleven of the 24 preoperative high-risk patients with negative SLNs were re-operated and 27 % presented positive non-SLNs. For the whole population, 3-year overall survival was 99 % (CI 95 % (97−1)) and 3-year recurrence-free survival (RFS) was 92 % (CI 95 % (0.87−0.95)). Conclusion Our study supports the feasibility of the SLN procedure for assessing risk recurrence in patients with early-stage EC. SLN biopsy should lead to major reductions in secondary staging and better adaptation of adjuvant therapy.

Aims: The aim of the present study was to compare the rate of actionable arrhythmic events between patients with hypertrophic cardiomyopathy (HCM) who are monitored with an insertable cardiac monitor (ICM) or Holter monitoring. Methods: We studied 50 patients (mean age 52 years, 72% men) with HCM at low or intermediate risk for sudden cardiac death (SCD), of whom 25 patients received an ICM between November 2014 and February 2019. We retrospectively identified a control group of 25 patients who were matched on age, sex, and HCM Risk-SCD score category. The mean HCM Risk-SCD score was 3.41 ± 1.31 and 3.31 ± 1.43 for the ICM and Holter groups, respectively. The primary endpoint was an actionable event which was defined as an arrhythmic event resulting in a change in patient management. The secondary endpoint was the occurrence of ventricular tachycardia (VT). Results: The cumulative actionable event rate at 30 months was higher in the ICM group (51 vs. 27%, log-rank p value n = 3). Overall, 4 implantable cardioverter-defibrillators were implanted for primary prevention (n = 2 in each group). The cumulative rate of VT episodes at 30 months was similar between groups (23% [ICM group] vs. 42% [Holter group], log-rank p value = 0.71). Furthermore, the characteristics of VT were similar between groups with regard to the number of beats and rate. Conclusions: In adults with HCM, an ICM will detect more arrhythmic events requiring an intervention than a conventional Holter strategy. In contrast, the diagnostic yield of detecting VT seems similar for both groups.

The effectiveness of postoperative radiotherapy (PORT) in improving outcomes remains debatable for oral squamous cell carcinoma (OSCC) patients with pathological intermediate-risk factors (IRFs) after surgery. A retrospective analysis was conducted on 432 intermediate-risk OSCC patients defined by histological reporting of close margin (

In differentiated thyroid cancer, radioiodine therapy (RIT) is usually carried out after thyroidectomy. Although the potent beneficial effects of radioiodine are undisputed in high-risk patients, much controversy remains surrounding many aspects of RIT in low- and intermediate-risk patients. Other than the indication for postoperative RIT, controversies also include, among others, the intent of RIT and the choice of activity for RIT or the mode of thyroid stimulating hormone stimulation. Furthermore, there is even controversy on the definition of what constitutes low- or intermediate-risk patients. Here the various issues will be discussed and an overview of the different points of view in a number of more prominent national and international guidelines and current literature is presented.

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is an effective and curative treatment for acute myeloid leukemia (AML). We explored the outcome of haploidentical donor (HID) transplantation for intermediate-risk AML and compared to that of matched sibling donor (MSD) transplants. One hundred twenty-seven consecutive patients with intermediate-risk AML in the first complete remission (CR1) who underwent allo-HSCT between January 1, 2015, and August 1, 2016, were enrolled. Thirty-seven patients received MSD grafts, and 90 received HID grafts. The 2-year leukemia-free survival (LFS) of the HID group was comparable to that of the MSD group: 82.0% ± 4.1% versus 82.7% ± 6.4%, P = 0.457. The 2-year cumulative incidences of relapse and transplantation-related mortality (TRM) were comparable between the HID and MSD groups (relapse, 4.5% ± 0.1%, versus 11.5% ± 0.3%, P = 0.550; TRM, 13.4% ± 0.1% vs. 5.8% ± 0.2%, P = 0.154). The HID recipients had a trend of a lower 2-year cumulative incidence of positive posttransplant flow cytometry (FCM+) and relapse than the MSD recipients (5.6% ± 0.1% vs. 19.9% ± 0.5%, P = 0.092). These results suggest that the outcomes of allo-HSCT with HIDs are comparable to those with MSDs in terms of LFS, TRM, and relapse for intermediate-risk AML in CR1. HIDs could be an alternative to MSDs for intermediate-risk AML.

Optimal treatment of intermediate risk prostate cancer remains unclear. National Comprehensive Cancer Network® guidelines recommend active surveillance, prostatectomy or radiotherapy. Recent trials demonstrated no difference in prostate cancer specific mortality for men undergoing active surveillance for low risk prostate cancer compared to prostatectomy or radiotherapy. The use of active surveillance for intermediate risk prostate cancer is less clear. In this study we characterize U.S. national trends for demographic, clinical and socioeconomic factors associated with active surveillance for men with intermediate risk prostate cancer.This retrospective cohort study examined 176,122 men diagnosed with intermediate risk prostate cancer from 2010 to 2016 in the National Cancer Database. Temporal trends in demographic, clinical and socioeconomic factors among men with intermediate risk prostate cancer and association with the use of active surveillance were characterized. The analysis was performed in April 2020.In total, 176,122 men were identified with intermediate risk prostate cancer from 2010 to 2016. Of these men 57.3% underwent prostatectomy, 36.4% underwent radiotherapy and 3.2% underwent active surveillance. Active surveillance nearly tripled from 1.6% in 2010 to 4.6% in 2016 (p0.001). On multivariate analysis use of active surveillance was associated with older age, diagnosis in recent years, lower Gleason score and tumor stage, type of insurance, treatment at an academic center and proximity to facility, and attaining higher education (p0.05). Race and comorbidities were not associated with active surveillance.Our findings highlight increasing active surveillance use for men with intermediate risk prostate cancer demonstrating clinical and socioeconomic disparities. Prospective data and improved risk stratification are needed to guide optimal treatment for men with intermediate risk prostate cancer.

The aim of this study was to assess the potential impact of the kinetics of serum levels of seven cytokines during induction in acute myeloid leukemia (AML) patients. Indeed, the role of cytokines, in the pathophysiology and response to therapy of AML patients, remains under investigation. Here, we report on the impact of peripheral levels of two cytokines, the Fms‐like tyrosine kinase 3 ligand (FL) and interleukin‐6 (IL‐6), evaluated during first‐line intensive induction. A new risk stratification can be proposed, which supersedes the ELN 2017 classification to predict survivals in AML patients by examining the kinetic profile of these cytokines during the induction phase. It segregates three groups of, respectively, high‐risk, characterized by a stagnation of low FL levels, intermediate risk, with dynamic increasing FL levels and high IL‐6 at day 22, and favorable risk with increasing FL levels but low IL‐6 at day 22., Here we report on the impact of the peripheral levels of two cytokines, the Fms‐like tyrosine kinase 3 ligand (FL), and interleukin‐6 (IL‐6), evaluated during first‐line intensive induction. Indeed, a new risk stratification can be proposed, which supersedes the ELN 2017 classification to predict survivals in AML patients by examining their profile during the induction phase.

We aimed to investigate the efficacy and tolerability of ultra-hypofractionated radiotherapy (UHRT) in the treatment of low and intermediate-risk prostate cancer patients.This retrospective study was conducted using data derived from 44 patients who underwent UHRT, and toxicity assessment and clinical response were investigated. Treatment consisted of 35-36.25 Gy in 5 fractions using stereotactic ablative radiotherapy (SABR) with the Linac-based delivery system.The median duration of follow-up was 52 months (8-68 months) and the median age was 71.5 years (54-85 years). Twenty-seven patients were assigned as intermediate-risk, whereas 17 patients had low-risk. The 5-year overall survival rate was 87.8%, while the 5-year biochemical recurrence-free survival (bRFS) rate was 97.4%. Acute grade 3 genitourinary (GU) side effect was not observed in any patient, whereas acute gastrointestinal (GI) system grade 3 side effect was seen in 6.8% of the patients. Late grade 3 GU and GI side effects were seen in 4.6% and 6.8% of the patients, respectively. In patients with planning target volume (PTV) ≥85 ml, acute grade ≥2 GU side effects were more common (Our data demonstrated that UHRT administered with volumetric arc therapy (VMAT) can be recommended for selected patients with low-intermediate risk prostate cancer. Further prospective, multicentric, controlled trials on larger series are warranted to reach more accurate conclusions.

BACKGROUND Intra-Operative Cholangiogram (IOC) is a procedure carried out during cholecystectomy with the primary objective of clearly delineating the biliary anatomy. Over decades, routine IOC became selective IOC and now it is being overtaken by less invasive investigations like MRCP and EUS. Role of IOC remains only to intraoperatively confirm or rule out bile duct injury in difficult cases. Laparoscopic IOC is a skilful procedure which requires training and extra added time during laparoscopic cholecystectomy. Once mastered it can be used in many situations for either anatomical reasons or to detect CBD pathology. METHODS All patients getting admitted for laparoscopic cholecystectomy with intermediate risk for choledocholithiasis were enrolled in the study from 2016 to 2019. Procedure was carried out with all necessary consents and precautions. All cases were performed by an experienced GI surgeon and followed up with proper protocol. RESULTS Fifty patients with known intermediate risk for choledocholithiasis underwent laparoscopic cholecystectomy with laparoscopic IOC. Procedure was successfully done in all patients except two, where cystic duct was very thin and cannulation was not possible. Forty-one (82%) patients had deranged liver function test and 9 patients (18%) had history of acute pancreatitis in the past as indications for the procedure. Two patients had dilated CBD (>6 mm) on ultrasound along with deranged liver function tests. An average of 12 minutes was taken to perform the procedure (range: 8 - 15 min). In cases where IOC took longer time was mainly due to technical issues (operability of C-arm). No IOC related complications occurred in any of the patients. Hospital stay was not prolonged in any of the patients due to IOC. None of the patients had any filling defect in CBD. All cases followed till date are asymptomatic. CONCLUSIONS It is a technically feasible procedure that can be performed with limited addition to OT time, minimal failure rate, and complications. All patients with limited criteria for intermediate risk of choledocholithiasis had a normal IOC with no evidence of biliary obstruction in follow up.

Background/Aim: Background/Aim: For intermediate risk acute myeloid leukemia patients, allogeneic hematopoietic stem cell transplantation (alloSCT) and chemotherapy are equally recommended as consolidation after first complete remission (CR1). In real-world, alloSCT might not be readily available, but there is paucity of data on the optimal timing of alloSCT for these patients. Patients and Methods: In this pilot study, we compared the outcomes of 13 patients undergoing alloSCT in CR1 with 13 patients undergoing alloSCT after relapse (non-CR1) to examine whether upfront alloSCT yields a better prognosis. Results: There were no differences between the two groups with regards to relapse-free survival (p=0.507) and overall survival (p=0.798). There were more chronic graft-versus-host-disease (GVHD) in the CR1 group compared to the non-CR group (p=0.001), but no difference in acute GVHD. Conclusion: The outcome of alloSCT after relapse is not inferior to that of alloSCT in CR1, supporting the role of alloSCT after relapse in the setting of limited donors and resources

The role of androgen deprivation therapy (ADT) in combination with radiotherapy (RT) in intermediate-risk prostate cancer (IRPC) remains controversial, particularly in patients receiving dose-escalated RT (DERT). We compared outcomes between patients with IRPC treated with ADT and two different doses of RT vs. RT alone.From December 2000 to September 2010, 600 patients with IRPC were randomised to a three-arm trial consisting of 6 months of ADT plus RT 70 Gy (ADT + RT70) vs. ADT plus a DERT of 76 Gy (ADT + DERT76) vs. DERT of 76 Gy alone (DERT76). Primary end-point was biochemical failure (BF), and secondary end-points were overall survival (OS) and toxicity. RT toxicity was assessed by Radiation Therapy Oncology Group/European Organisation for Research and Treatment of Cancer criteria.With a median follow-up of 11.3 years (interquartile range: 10.9-11.7), patients receiving DERT76 alone, compared with patients receiving ADT + RT70 and ADT + DERT76, had higher rates of BF (32%, 18% and 14%, respectively, p 0.001), higher rates of prostate cancer progression (12%, 4.5% and 3.3%, respectively, p = 0.001) and more deaths due to prostate cancer (6.5%, 3.0% and 1.5%, respectively, p = 0.03) with no significant difference seen between ADT + RT70 and ADT + DERT76. There was no significant difference in OS between the 3 arms. A higher dose of RT (76 Gy) increased late gastrointestinal (GI) toxicity grade ≥ II compared with lower dose (70 Gy) (16% vs 5.3%, p 0.001) with no statistical difference for late genitourinary toxicity.In IRPC, the addition of 6 months of ADT to RT70 or DERT76 significantly improves BF and appears to decrease the risk of death from prostate cancer compared with DERT76 alone with no difference in OS. In the setting of IRPC, ADT plus RT 70 Gy yields effective disease control with a better GI toxicity profile. Clinicaltrials.gov#NCT00223145.

BACKGROUND AND OBJECTIVES: The selection of escalation of care strategies for the treatment of intermediate-risk pulmonary embolism (PE) is a matter of debate. Here, we aimed to assess the features of our population treated either with anticoagulation (AC) alone or catheter-directed thrombolysis (CDT). We also sought to identify a relationship between high residual systolic pulmonary artery pressure (sPAP) and demographic and clinical variables. PATIENTS AND METHODS: The retrospective data of 30 intermediate-high-risk PE patients were analyzed. CDT was used in 14 (46.7%) cases. Enoxaparin (b. i. d) injections were administered in the AC group. In the CDT group, patients received 5 mg bolus dose of alteplase followed by 1 mg/h infusion for 24 h. Estimated sPAP at presentation and discharge was recorded. A value equal to or greater than 40 mmHg in the latter was accepted as a significant rise. RESULTS: The patients in the CDT group had a lower HAS-BLED score (2 [0-3] vs. 1 [0-3], P = 0.03). Although initial sPAP values were comparable among treatment arms, sPAP at discharge was significantly lower in the CDT group (mmHg, 42 +/- 11.2 vs. 33.6 +/- 9.7, P = 0.04). The reduction in sPAP at discharge was also significantly higher in this group. The degree of reduction in sPAP was considerably correlated with baseline sPAP (r: 63.2, P < 0.001). Finally, the baseline sPAP measurement and HAS-BLED score of the patients with high residual sPAP were significantly higher (56.6 +/- 13.1 vs. 67.3 +/- 11.3, P = 0.02, and 1 [0-3] vs. 2 [0-3], P = 0.02, respectively). CONCLUSION: CDT was preferred over AC when lower bleeding risk was anticipated for intermediate-high-risk PE patients in our sample population. Eventually, CDT provided lower discharge sPAP levels and a greater reduction in sPAP. However, the factors associated with high sPAP at discharge were only high baseline sPAP measurement and HAS-BLED score.

Objective There is an increasing amount of evidence supporting use of transcatheter aortic valve replacement (TAVR) for treatment of aortic stenosis in patients at low or intermediate risk for surgical aortic valve replacement (SAVR). TAVR is now approved for use in all patient cohorts. Despite this, there remains debate about the relative efficacy of TAVR compared with SAVR in lower-risk cohorts and various subgroups of patients. We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) and propensity-matched trials to guide a consensus among expert cardiologists and surgeons. Methods Studies comparing TAVR and SAVR in low- and intermediate-risk patients were identified by a thorough search of the major databases. Mortality, stroke, and other perioperative outcomes were assessed at 30 days and 1 year. Results Early mortality was lower in TAVR compared to SAVR in RCTs, but not propensity-matched studies in low-risk cohorts (0.66% vs 1.5%; odds ratio [OR] = 0.44, 95% confidence interval [CI] 0.20 to 0.98, I2 = 0%). No difference in mortality between TAVR and SAVR was identified in intermediate-risk patients at early or later time points. Incidence of perioperative stroke in 3 low-risk RCTs was significantly lower in TAVR (0.4%) than SAVR (1.4%; OR = 0.33, 95% CI 0.13 to 0.81, I2 = 0%). There was no difference in stroke for intermediate-risk patients between TAVR and SAVR. The expert panel of cardiologists and cardiac surgeons provided recommendations for TAVR and SAVR in various clinical scenarios. Conclusions In RCTs comparing TAVR and SAVR in low-risk patients, early mortality and stroke were lower in TAVR, but did not differ at 1 year. There was no difference in mortality and stroke in intermediate-risk patients. The Multidisciplinary Heart Team must consider individual patient characteristics and preferences when recommending TAVR or SAVR. The decision must consider the long-term management of each patient’s aortic valve disease.

Introduction: Surgical treatment of thyroid cancer has become less aggressive but for many patients, the threshold for performing total thyroidectomy (TT), as opposed to thyroid lobectomy (TL), has remained unclear. Current American Thyroid Association (ATA) guidelines encourage more individualization of treatment options, which necessitates explicit review of the pros and cons of the different options with patients.Areas covered: This review focuses on the extent of surgery for treatment of intermediate-risk differentiated thyroid cancer, restricted to relevant literature available after publication of the 2015 ATA guidelines.Expert opinion: Dynamic risk-stratification facilitates a tailored approach when deciding on the extent of surgery for thyroid cancer. Treatment with TT allows for a lower recurrence risk, a simpler follow-up regimen, and treatment with adjuvant post-operative radioactive iodine. Treatment with TL has a lower associated risk of complications and avoidance of lifelong thyroid hormone replacement but has a significant risk of requiring a completion thyroid lobectomy (CT). Overall, treatment with TL and TT have comparable survival outcomes, but TL is the more cost-effective option. Larger cancer size is correlated with worse clinical outcomes, and numerous subgroup analyses have shown poorer outcomes for cancers with a diameter that is 2-4 cm compared to 1-2 cm.

Summary Purpose The intermediate-risk (IR) prostate cancer (PCa) group is heterogeneous in terms of prognosis. For unfavorable or favorable IR PCa treated by radiotherapy, the optimal strategy remains to be defined. In routine practice, the physician's decision to propose hormonal therapy (HT) is controversial. The PROACT survey aimed to evaluate pattern and preferences of daily practice in France in this IR population. Materials and methods A web questionnaire was distributed to French radiotherapy members of 91 centers of the Groupe d’Etude des Tumeurs Uro-Genitales (GETUG). The questionnaire included four sections concerning: (i) the specialists who prescribe treatments and multidisciplinary decisions (MTD) validation; (ii) the definition of IR subsets of patients; (iii) radiotherapy parameters; (iv) the pattern of practice regarding cardiovascular (CV) and (iv) metabolic evaluation. A descriptive presentation of the results was used. Results Among the 82 responses (90% of the centers), HT schedules and irradiation techniques were validated by specific board meetings in 54% and 45% of the centers, respectively. Three-fourths (76%) of the centers identified a subset of IR patients for a dedicated strategy. The majority of centers consider PSA > 15 (77%) and/or Gleason 7 (4 + 3) (87%) for an unfavorable IR definition. Overall, 41% of the centers performed systematically a CV evaluation before HT prescription while 61% consider only CV history/status in defining the type of HT. LHRH agonists are more frequently prescribed in both favorable (70%) and unfavorable (98%) IR patients. Finally, weight (80%), metabolic profile (70%) and CV status (77%) of patients are considered for follow-up under HT. Conclusion To the best of our knowledge, this is the first survey on HT practice in IR PCa. The PROACT survey indicates that three-quarters of the respondents identify subsets of IR-patients in tailoring therapy. The CV status of the patient is considered in guiding the HT decision, its duration and type of drug.

Introduction The accurate diagnosis of heparin-induced thrombocytopenia (HIT) is essential to ensure adequate treatment and prevent complications. First step diagnosis test are immunoassays including enzyme-linked immunosorbent assays (ELISAs) and rapid immunoassays. Methods Using a Bayesian approach, we prospectively evaluated the performance of the IgG PF4/polyvinylsulfonate ELISA and a chemiluminescent immunoassay (CLIA), which are specific for IgG and use the same antigenic target to detect HIT antibodies. Results One hundred and eighty-four 184 consecutive patients with an intermediate (n = 159) or high (n = 25) clinical pretest probability of HIT based on the 4Ts score or platelet pattern were included. Both immunoassays (IAs) were performed on all 184 samples, and definite HIT was confirmed with a positive serotonin release assay in 29 patients (12.7%). The sensitivity (Ss) and negative predictive value (NPV) of ELISA were excellent (100%) allowing HIT to be excluded with good confidence when the test was negative. In addition, the Ss and NPV of the CLIA equalled 93.1% and 98.6%, respectively, as it was negative in two definite HIT. When the CLIA was negative, the post-test probability of HIT was 0.7% in case of intermediate risk. Although there was excellent agreement between CLIA and ELISA results, the quantitative values provided by the two IAs were not correlated. Conclusion AcuStar HIT® detects more than 90% of HIT, as do all rapid IAs, and appears to be a good tool for excluding HIT when the pretest probability is intermediate. A chemiluminescent signal higher than 10 IU/mL is highly predictive of definite HIT with a PPV of 100%.

Objectives To evaluate the impact of implementing a modified Pediatric Emergency Care Applied Research Network (PECARN) rule including the S100B protein assay for managing mild traumatic brain injury (mTBI) in children. Methods A before-and-after study was conducted in a paediatric emergency department of a French University Hospital from 2013 to 2015. We retrospectively included all consecutive children aged 4 months to 15 years who presented mTBI and were at intermediate risk for clinically important traumatic brain injury (ciTBI). We compared the proportions of CT scans performed and of in-hospital observations before (2013–2014) and after (2014–2015) implementation of a modified PECARN rule including the S100B protein assay. Results We included 1,062 children with mTBI (median age 4.5 years, sex ratio [F/M] 0.73) who were at intermediate risk for ciTBI: 494 (46.5%) during 2013–2014 and 568 (53.5%) during 2014–2015. During 2014–2015, S100B protein was measured in 451 (79.4%) children within 6 h after mTBI. The proportion of CT scans and in-hospital observations significantly decreased between the two periods, from 14.4 to 9.5% (p=0.02) and 73.9–40.5% (p Conclusions The implementation of a modified PECARN rule including the S100B protein assay significantly decreased the proportion of CT scans and in-hospital observations for children with mTBI who were at intermediate risk for ciTBI.

Background: Misclassification rates defined as upgrading, upstaging, and upgrading and/or upstaging have not been tested in contemporary Black patients relative to White patients who fulfilled criteria for very-low-risk, low-risk, or favorable intermediate-risk prostate cancer. This study aimed to address this void. Methods: Within the SEER database (2010–2015), we focused on patients with very low, low, and favorable intermediate risk for prostate cancer who underwent radical prostatectomy and had available stage and grade information. Descriptive analyses, temporal trend analyses, and multivariate logistic regression analyses were used. Results: Overall, 4,704 patients with very low risk (701 Black vs 4,003 White), 17,785 with low risk (2,696 Black vs 15,089 White), and 11,040 with favorable intermediate risk (1,693 Black vs 9,347 White) were identified. Rates of upgrading and/or upstaging in Black versus White patients were respectively 42.1% versus 37.7% (absolute Δ = +4.4%; PPP=.05) in those with favorable intermediate risk. Conclusions: Rates of misclassification were particularly elevated in patients with very low risk and low risk, regardless of race, and ranged from 33.8% to 48.6%. Recalibration of very-low-, low-, and, to a lesser extent, favorable intermediate-risk active surveillance criteria may be required. Finally, our data indicate that Black patients may be given the same consideration as White patients when active surveillance is an option. However, further validations should ideally follow.

The presence of minimal residual disease (MRD) is a risk factor for relapse among children with acute myeloid leukemia (AML), and eliminating MRD can usually improve survival rates. To investigate the effect of expanded activated autologous lymphocytes (EAALs) combined with chemotherapy on eliminating MRD and improving survival rates of children with AML, we retrospectively analyzed the results of 115 children with low- or intermediate-risk AML with MRD treated at the Pediatric Hematological Center, Peking University People's Hospital, between January 2010 and January 2016. The patients were assigned to the chemotherapy plus EAAL (combined therapy) group (n = 61) and chemotherapy group (n = 54). The MRD-negativity rates were 95.1% (58/61) in the combined therapy group and 63.0% (34/54) in the chemotherapy group (P 0.0001) during consolidation treatment. The 5-year event-free survival rate was higher in the combined therapy group than in the chemotherapy group (86.3 ± 4.6% vs. 72.1 ± 6.1%, P = 0.025). No severe adverse event was observed after EAAL infusion. The present study showed that EAAL combined with chemotherapy could improve the MRD-negativity rate and event-free survival rate among children with AML with low level MRD-positive status.
