Decision to perform additional surgery after non-curative endoscopic submucosal dissection for gastric cancer based on the risk of lymph node metastasis: a long-term follow-up study.

Radical surgery after non-curative endoscopic submucosal dissection (ESD) for early gastric cancer (EGC) may be excessive, since only 5-10% of patients have lymph node metastasis (LNM). This study investigated the suitability of the eCura system for determining the need for radical surgery after non-curative ESD. We retrospectively investigated 343 patients who underwent non-curative ESD for EGC from 2006 to 2021 at a tertiary hospital in Korea. These patients were divided into surgery (n = 191) and observation (n = 152) groups based on whether they underwent additional surgery post-ESD. Each group was further classified into low-risk (eCura score 0-1), intermediate-risk (eCura score 2-4) and high-risk (eCura score 5-7). All patients were regularly followed-up at least annually after the initial treatment. The cumulative overall and recurrence-free survival rates were calculated for each category and compared between the surgery and observation groups. No significant differences in overall survival were found between the surgery and observation groups in low-risk (p = 0.168) and intermediate-risk patients (p = 0.306); however, high-risk patients had better 5-year overall survival rate in the surgery group than in the follow-up group (95.2% vs. 71.4%, p < 0.001). The 5-year recurrence-free survival rate was higher in the surgery group than in the observation group for low-risk (100% vs. 84.3%; p = 0.034), intermediate-risk (96.1% vs. 88.4%; p = 0.081) and high-risk patients (100% vs. 83.3%; p = 0.023). Follow-up without additional surgery after non-curative ESD can be a reasonable option for low-risk and even intermediate-risk patients according to the eCura system. However, surgery is warranted for eCura high-risk patients.

Rapid access chest pain clinics in Australia and New Zealand.

Chest pain is the second most common reason for adult emergency department presentations. Most patients have low or intermediate risk chest pain, which historically has led to inpatient admission for further evaluation. Rapid access chest pain clinics represent an innovative outpatient pathway for these low and intermediate risk patients, and have been shown to be safe and reduce hospital costs. Despite variations in rapid access chest pain clinic models, there are limited data to determine the most effective approach. Developing a national framework could be beneficial to provide sites with evidence, possible models, and business cases. Multicentre data analysis could enhance understanding and monitoring of the service.

TAVR in Intermediate-Risk Patients: 5-Year Outcomes From the SURTAVI Continued Access Study

TAVR in Intermediate-Risk Patients: 5-Year Outcomes From the SURTAVI Continued Access Study

Comparative Effectiveness of Coronary CT Angiography and Standard of Care for Evaluating Acute Chest Pain: A Living Systematic Review and Meta-Analysis.

To perform a living systematic review and meta-analysis of randomized controlled trials comparing the effectiveness of coronary CT angiography (CCTA) and standard of care (SOC) in the evaluation of acute chest pain (ACP). Multiple electronic databases were systematically searched, with the most recent search conducted on October 31, 2022. Studies were stratified into two groups according to the pretest probability for acute coronary syndrome (group 1 with predominantly low-to-intermediate risk vs group 2 with high risk). A meta-regression analysis was also conducted using participant risk, type of SOC used, and the use or nonuse of high-sensitivity troponins as independent variables. The final analysis included 22 randomized controlled trials (9379 total participants; 4956 assigned to CCTA arms and 4423 to SOC arms). There was a 14% reduction in the length of stay and a 17% reduction in immediate costs for the CCTA arm compared with the SOC arm. In group 1, the length of stay was 17% shorter and costs were 21% lower using CCTA. There was no evidence of differences in referrals to invasive coronary angiography, myocardial infarction, mortality, rate of hospitalization, further stress testing, or readmissions between CCTA and SOC arms. There were more revascularizations (relative risk, 1.45) and medication changes (relative risk, 1.33) in participants with low-to-intermediate acute coronary syndrome risk and increased radiation exposure in high-risk participants (mean difference, 7.24 mSv) in the CCTA arm compared with the SOC arm. The meta-regression analysis found significant differences between CCTA and SOC arms for rate of hospitalization, further stress testing, and medication changes depending on the type of SOC (P < .05). The results support the use of CCTA as a safe, rapid, and less expensive in the short term strategy to exclude acute coronary syndrome in low- to intermediate-risk patients presenting with acute chest pain.Keywords: Acute Coronary Syndrome, Chest Pain, Emergency Department, Coronary Computed Tomography, Usual Care Supplemental material is available for this article.

Use of Clinical and Echocardiographic Evaluation to Assess the Risk of Heart Failure

BackgroundClinical and echocardiographic features predict incident heart failure (HF), but the optimal strategy for combining them is unclear. ObjectivesThis study sought to define an effective means of using echocardiography in HF risk evaluation. MethodsThe same clinical and echocardiographic evaluation was obtained in 2 groups with HF risk factors: a training group (n = 926, followed to 7 years) and a validation group (n = 355, followed to 10 years). Clinical risk was categorized as low, intermediate, and high using 4-year ARIC (Atherosclerosis Risk In Communities) HF risk score cutpoints of 9% and 33%. A risk stratification algorithm based on clinical risk and echocardiographic markers of stage B HF (SBHF) (abnormal global longitudinal strain [GLS], diastolic dysfunction, or left ventricular hypertrophy) was developed using a classification and regression tree analysis and was validated. ResultsHF developed in 12% of the training group, including 9%, 18%, and 73% of low-, intermediate-, and high-risk patients. HF occurred in 8.6% of stage A HF and 19.4% of SBHF (P < 0.001), but stage A HF with clinical risk of ≥9% had similar outcome to SBHF. Abnormal GLS (HR: 2.92 [95% CI: 1.95-4.37]; P < 0.001) was the strongest independent predictor of HF. Normal GLS and diastolic function reclassified 61% of the intermediate-risk group into the low-risk group (HF incidence: 12%). In the validation group, 11% developed HF over 4.5 years; 4%, 17%, and 39% of low-, intermediate-, and high-risk groups. Similar results were obtained after exclusion of patients with known coronary artery disease. The echocardiographic parameters also provided significant incremental value to the ARIC score in predicting new HF admission (C-statistic: 0.78 [95% CI: 0.71-0.84] vs 0.83 [95% CI: 0.77-0.88]; P = 0.027). ConclusionsClinical risk assessment is adequate to classify low and high HF risk. Echocardiographic evaluation reclassifies 61% of intermediate-risk patients.

Real-world Outcome of Patients with Advanced Renal Cell Carcinoma and Intermediate- or Poor-risk International Metastatic Renal Cell Carcinoma Database Consortium Criteria Treated by Immune-oncology Combinations: Differential Effectiveness by Risk Group?

BackgroundRenal c carcinoma (RCC) is one of the most common urinary cancers worldwide, with a predicted increase in incidence in the coming years. Immunotherapy, as a single agent, in doublets, or in combination with anti–vascular endothelial growth factor receptor tyrosine kinase inhibitors (TKIs), has rapidly become a cornerstone of the RCC therapeutic scenario, but no head-to-head comparisons have been made. In this setting, real-world evidence emerges as a cornerstone to guide clinical decisions. ObjectiveThe objective of this retrospective study was to assess the outcome of patients treated with first-line immune combinations or immune oncology (IO)-TKIs for advanced RCC. Design, setting, and participantsData from 930 patients, 654 intermediate risk and 276 poor risk, were collected retrospectively from 58 centers in 20 countries. Special data such as sarcomatoid differentiation, body mass index, prior nephrectomy, and metastatic localization, in addition to biochemical data such as hemoglobin, platelets, calcium, lactate dehydrogenase, neutrophils, and radiological response by investigator's criteria, were collected. Outcome measurements and statistical analysisOverall survival (OS) and progression-free survival (PFS) were estimated using the Kaplan-Meier method. The median follow-up was calculated by the inverse Kaplan-Meier method. Results and limitationsThe median follow-up time was 18.7 mo. In the 654 intermediate-risk patients, the median OS and PFS were significantly longer in patients with the intermediate than in those with the poor International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) criteria (38.9 vs 17.3 mo, 95% confidence interval [CI] p < 0.001, and 17.3 vs 11.6 mo, 95% CI p < 0.001, respectively). In the intermediate-risk subgroup, the OS was 55.7 mo (95% CI 31.4–55.7) and 40.2 mo (95% CI 29.6–51.6) in patients treated with IO + TKI and IO + IO combinations, respectively (p = 0.047). PFS was 30.7 mo (95% CI 16.5–55.7) and 13.2 mo (95% CI 29.6–51.6) in intermediate-risk patients treated with IO + TKI and IO + IO combinations, respectively (p < 0.001). In the poor-risk subgroup, the median OS and PFS did not show a statistically significant difference between IO + IO and IO + TKI. Our study presents several limitations, mainly due to its retrospective nature. ConclusionsOur results showed differences between the IO + TKI and IO + IO combinations in intermediate-risk patients. A clear association with longer PFS and OS in favor of patients who received the IO + TKI combinations compared with the IO-IO combination was observed. Instead, in the poor-risk group, we observed no significant difference in PFS or OS between patients who received different combinations. Patient summaryRenal cancer is one of the most frequent genitourinary tumors. Treatment is currently based on immunotherapy combinations or immunotherapy with tyrosine kinase inhibitors, but there are no comparisons between these.In this study, we have analyzed the clinical course of 930 patients from 58 centers in 20 countries around the world. We aimed to analyze the differences between the two main treatment strategies, combination of two immunotherapies versus immunotherapy + antiangiogenic therapy, and found in real-life data that intermediate-risk patients (approximately 60% of patients with metastatic renal cancer) seem to benefit more from the combination of immunotherapy + antiangiogenic therapy than from double immunotherapy. No such differences were found in poor-risk patients. This may have important implications in daily practice decision-making for these patients.

Persistence of racial and ethnic disparities in risk and survival for patients with neuroblastoma over two decades

BackgroundRacial/ethnic survival disparities in neuroblastoma were first reported more than a decade ago. We sought to investigate if these disparities have persisted with current era therapy. MethodsTwo patient cohorts were identified in the International Neuroblastoma Risk Group Data Commons (INRGdc) (Cohort 1: diagnosed 2001–2009, n = 4359; Cohort 2: diagnosed 2010–2019, n = 4891). Chi-squared tests were used to assess the relationship between race/ethnicity and clinical and biologic features. Survival was estimated by the Kaplan-Meier method. Cox proportional hazards regression analyses were performed to investigate the association between racial/ethnic groups and prognostic markers. ResultsSignificantly higher 5-year event-free survival (EFS) and overall survival (OS) were observed for Cohort 2 compared to Cohort 1 (P < 0.001 and P < 0.001, respectively). Compared to White patients, Black patients in both cohorts had a higher proportion of high-risk disease (Cohort 1: P < 0.001; Cohort 2: P < 0.001) and worse EFS (Cohort 1: P < 0.001; Cohort 2 P < 0.001) and OS (Cohort 1: P < 0.001; Cohort 2: P < 0.001). In Cohort 1, Native Americans also had a higher proportion of high-risk disease (P = 0.03) and inferior EFS/OS. No significant survival disparities were observed for low- or intermediate-risk patients in either cohort or high-risk patients in Cohort 1. Hispanic patients with high-risk disease in Cohort 2 had significantly inferior OS (P = 0.047). Significantly worse OS, but not EFS, (P = 0.006 and P = 0.02, respectively) was also observed among Black and Hispanic patients assigned to receive post-Consolidation dinutuximab on clinical trials (n = 885). ConclusionRacial/ethnic survival disparities have persisted over time and were observed among high-risk patients assigned to receive post-Consolidation dinutuximab.

MRI lesion size is more important than the number of positive biopsy cores in predicting adverse features and recurrence after radical prostatectomy: implications for active surveillance criteria in intermediate-risk patients.

To determine associations between prostate cancer (PCa) tumor burden measured on biopsy or multiparametric magnetic resonance imaging (mpMRI) and outcomes in intermediate-risk (IR) International Society of Urological Pathology (ISUP) grade 2 men managed with primary radical prostatectomy (RP). This retrospective, multicenter study was conducted in eight referral centers. The cohort included IR PCa patients who had ISUP 2 at biopsy. We defined biopsy tumor burden as low/high based on the absence/presence of more than 25% positive cores. Tumor burden on imaging was defined as low/high based on maximum lesion diameter, <15 mm and ≥15 mm at mpMRI, respectively. The histological endpoint of the study was adverse features at RP, defined as ≥pT3a stage and/or lymph node invasion and/or ISUP ≥3 at final pathology. The clinical endpoint was biochemical recurrence (BCR) after RP. A total of 698 IR patients was included, of whom 335 (48%) had adverse features. In multivariate logistic regression analysis, there was no statistical association between tumor burden at biopsy and adverse features (p = 0.7). Tumor size ≥15 mm at mpMRI was significantly associated with adverse pathology (OR 1.65, 95%CI 1.14-2.39; p = 0.01). No significant association was observed between tumor burden at biopsy and BCR (p = 0.4). Tumor size ≥15 mm at mpMRI was significantly associated with BCR (HR 1.96, 95% CI 1.01-3.80; p = 0.04). Our data support extending the inclusion criteria to ISUP 2 men with >25% positive cores, provided they have a low tumor size at mpMRI (<15 mm). Prospective studies should be performed to validate these findings.

Risk stratification of pulmonary embolism.

Pulmonary embolism is the third most frequent type of cardiovascular disease behind coronary artery disease and stroke. Patients with acute pulmonary embolism have significant variability in short-term mortality from less than 0.6% in low-risk patients to 19% in high-risk patients. Risk stratification plays an important role in the management of acute pulmonary embolism as it can determine the need for urgent reperfusion therapies versus conservative strategies. The three fundamental steps of risk stratification include the immediate identification of patients that are at high risk for mortality, the identification of patients that are at an increased risk of complications from pulmonary embolism that requires hospital monitoring and potential escalation of therapies, and the identification of patients at a low risk that can be treated as an outpatient. It is vital to immediately identify high-risk patients for mortality so that they can be evaluated for urgent reperfusion therapies to improve outcomes. Risk stratification for intermediate-risk patients is based on right ventricular dysfunction in patients with hemodynamic stability. RV dysfunction can be assessed by clinical signs and symptoms along with ECHO and cardiac biomarkers. Identifying the low-risk population can help reduce the healthcare burden by allowing for early discharge and outpatient management.

Prognostic significance of positive peritoneal cytology in endometrial carcinoma based on ESGO/ESTRO/ESP risk classification: A multicenter retrospective study

ObjectiveThis study aimed to determine the prognostic significance of positive peritoneal cytology (PC) on endometrial carcinoma (EC) patients under the ESGO/ESTRO/ESP risk classification. MethodsThis study retrospectively analyzed EC patients from 27 medical centers in China from 2000 to 2019. Patients were divided into three ESGO risk groups: low-risk, intermediate-risk and high-intermediate risk, and high-risk groups. The covariates were balanced by using the propensity score-based inverse probability of treatment weighting (PS-IPTW). The prognostic significance of PC was assessed by Kaplan-Meier curves and multivariate Cox regression analysis. ResultsA total of 6313 EC patients with PC results were included and positive PC was reported in 384 women (6.1%). The multivariate Cox analysis in all patients showed the positive PC was significantly associated with decreased PFS (hazard ratio [HR] 2.20, 95% confidence interval [CI] 1.55–3.13, P < 0.001) and OS (HR 2.25, 95% CI 1.49–3.40, P < 0.001),and the Kaplan-Meier curves also showed a poor survival in the intermediate and high-intermediate risk group (5-year PFS: 75.5% vs. 93.0%, P < 0.001; 5-year OS: 78.3% vs. 96.4%, P < 0.001); While in the low-risk group, there were no significant differences in PFS and OS between different PC status (5-year PFS: 93.1% vs. 97.3%, P = 0.124; 5-year OS: 98.6% vs. 98.2%, P = 0.823); in the high-risk group, significant difference was only found in PFS (5-year PFS: 62.5% vs. 77.9%, P = 0.033). ConclusionPositive PC was an adverse prognostic factor for EC, especially in the intermediate and high-intermediate risk patients. Gynecologic oncologists should reconsider the effect of positive PC on different ESGO risk groups.

Combined Band and Plate Fixation as a New Individual Option for Patients at Risk of Sternal Complications after Cardiac Surgery: A Single-Center Experience.

Due to the advent of interventional therapies for low- and intermediate-risk patients, case complexity has increased in cardiac surgery over the last decades. Despite the surgical progress achieved to keep up with the increase in the number of high-risk patients, the prevention of sternal complications remains a challenge requiring new, individualized sternal closure techniques. The aim of this study was to evaluate the safety and feasibility, as well as the in-hospital and long-term outcomes, of enhanced sternal closure with combined band and plate fixation using the new SternaLock® 360 (SL360) system as an alternative to sternal wiring. From 2020 to 2022, 17 patients underwent enhanced sternal closure using the SL360 at our institution. We analyzed perioperative data, as well as clinical and radiologic follow-up data. The results were as follows: In total, 82% of the patients were treated with the SL360 based on perioperative risk factors, while in 18% of cases, the SL360 was used for secondary closure due to sternal instability. No perioperative complications were observed. We obtained the follow-up data of 82% of the patients (median follow-up time: 141 (47.8 to 511.5) days), showing no surgical revision, no sternal instability, no deep wound infections, and no sternal pain at the follow-up. In one case, a superficial wound infection was treated with antibiotics. In conclusion, enhanced sternal closure with the SL360 is easy to perform, effective, and safe. This system might be considered for both primary and secondary sternal closure in patients at risk of sternal complications.

HLA-mismatched micro-transplantation as post-remission treatment compared to autologous hematopoietic stem cell transplantation or consolidation with single agent cytarabine for favorable-or intermediate-risk acute myeloid leukemia

ABSTRACTObjectivesOptimal post-remission treatment for individual favorable and intermediate risk acute myeloid leukemia (AML) patients has not yet been established. Human leukocyte antigen (HLA)-mismatched stem cell microtransplantation (MST), may improve outcomes and avoid graft-versus-host disease in patients with first complete remission of AML.MethodsWe retrospectively analyzed the efficacy, safety, and survival of 63 patients with favorable- or intermediate-risk AML who received MST, autologous stem cell transplantation (ASCT), or cytarabine single agent (CSA) as post-remission treatment from January 2014 to August 2021.ResultsThe neutrophil recovery time was shorter in the MST group than in the CSA group. The 2-year cumulative incidences of relapse in the MST, ASCT, and CSA groups were 27.27%, 29.41%, and 41.67%, respectively. During follow-up, 21 patients (33.30%) died of relapse, including six (9.52%), five (7.94%), and 10 (15.84%) in the MST, ASCT, and CSA groups, respectively. The estimated 2-year overall survival (OS) and relapse-free survival (RFS) were 62.20% vs. 50.00% (P = 0.101) and 57.10% vs. 50.00% (P = 0.136), in the >60 years MST and CSA groups (P = 0.101). The estimated 2-year OS was 100%, 66.20%, and 69.10% in the MST, ASCT, and CSA groups (MST vs CSA, P = 0.044), meanwhile, the estimated 2-year RFS was 100%, 65.40%, and 59.80% in patients ≤60 years.ConclusionMST, ASCT, and CSA are acceptable post-remission treatments for patients with favorable- and intermediate-risk AML and may not only improve the prognosis of the elderly but also prolong the OS and RFS of favorable- or intermediate-risk patients ≤60 years.

Outcomes of SAPIEN 3 Transcatheter Aortic Valve Replacement Compared With Surgical Valve Replacement in Intermediate-Risk Patients

BackgroundPrevious studies demonstrated transcatheter aortic valve replacement (TAVR) with an earlier generation balloon-expandable valve to be noninferior to surgical aortic valve replacement (SAVR) for death and disabling stroke in intermediate-risk patients with symptomatic, severe aortic stenosis at 5 years. However, limited long-term data are available with the more contemporary SAPIEN 3 (S3) bioprosthesis. ObjectivesThe aim of this study was to compare 5-year risk-adjusted outcomes in intermediate-risk patients undergoing S3 TAVR vs SAVR. MethodsPropensity score matching was performed to account for baseline differences in intermediate-risk patients undergoing S3 TAVR in the PARTNER 2 (Placement of Aortic Transcatheter Valves) S3 single-arm study and SAVR in the PARTNER 2A randomized clinical trial. The primary composite endpoint consisted of 5-year all-cause death and disabling stroke. ResultsA total of 783 matched pairs of intermediate-risk patients with severe aortic stenosis were studied. There were no differences in the primary endpoint between S3 TAVR and SAVR at 5 years (40.2% vs 42.7%; HR: 0.87; 95% CI: 0.74-1.03; P = 0.10). The incidence of mild or greater paravalvular regurgitation was more common after S3 TAVR. There were no differences in structural valve deterioration–related stage 2 and 3 hemodynamic valve deterioration or bioprosthetic valve failure. ConclusionsIn this propensity-matched analysis of intermediate-risk patients, 5-year rates of death and disabling stroke were similar between S3 TAVR and SAVR. Rates of structural valve deterioration–related hemodynamic valve deterioration were similar, but paravalvular regurgitation was more common after S3 TAVR. Longer-term follow-up is needed to further evaluate differences in late adverse clinical events and bioprosthetic valve durability.

Predicting Coronary Artery Disease in Intermediate Risk Patients Presenting with Chest Pain

Predicting Coronary Artery Disease in Intermediate Risk Patients Presenting with Chest Pain

Management of Pulmonary Arterial Hypertension.

Pulmonary arterial hypertension (PAH) is a rare pulmonary vascular disease characterized by progressive pulmonary arterial remodeling, increased pulmonary vascular resistance, right ventricular dysfunction, and reduced survival. Effective therapies have been developed that target three pathobiologic pathways in PAH: nitric oxide, endothelin-1, and prostacyclin. Approved therapies for PAH include phosphodiesterase type-5 inhibitors, soluble guanylate cyclase stimulators, endothelin receptor antagonists, prostacyclin analogs, and prostacyclin receptor agonists. Management of PAH in the modern era incorporates multidimensional risk assessment to guide the use of these medications. For patients with PAH and without significant comorbidities, current guidelines recommend two oral medications (phosphodiesterase type-5 inhibitor and endothelin receptor antagonist) for low- and intermediate-risk patients, with triple therapy including a parenteral prostacyclin to be considered in those at high or intermediate-high risk. Combination therapy may be poorly tolerated and less effective in patients with PAH and cardiopulmonary comorbidities. Thus, a single-agent approach with individualized decisions to add-on other PAH therapies is recommended in older patients and those with significant comorbid conditions. Management of PAH is best performed in multidisciplinary teams located in experienced centers. Other core pillars of PAH management include supportive and adjunctive treatments including oxygen, diuretics, rehabilitation, and anticoagulation in certain patients. Patients with PAH who progress despite optimal treatment or who are refractory to best medical care should be referred for lung transplantation, if eligible. Despite considerable progress, PAH is often fatal and new therapies that reverse the disease and improve outcomes are desperately needed.

Survival After Cryotherapy Versus Radiotherapy in Low and Intermediate Risk Localized Prostate Cancer

BackgroundFocal therapy, including cryotherapy, reduces overtreatment in low- and intermediate-risk prostate cancer (PCa) patients with multiple comorbidities, which seems to increase in popularity compared with whole gland treatment. However, there is currently no consensus regarding the medium-term outcomes of cryosurgery as a prospective alternative to radiotherapy (RT) for such patients. Our study aims to find the available evidence that directly compares the medium-term overall survival (OS) and cancer-specific mortality (CSM) outcomes between cryotherapy and RT in patients with low- and intermediated-risk PCa. Materials and MethodUsing the Surveillance, Epidemiology, and End Results (SEER) database, we identified 47,787 patients with low- and intermediate-risk PCa diagnosed between 2004 and 2015, of which 46,853 (98%) received treatment with RT, while only 934 (2.0%) received treatment with cryotherapy. Kaplan–Meier methods were used to estimateOS and cancer-specific survival (CSS) between the 2 groups. We performed multivariable Cox regression analysis to assess overall mortality (OM), while the cumulative incidence function (CIF) was used to illustrate cancer-specific mortality (CSM) and noncancer-specific mortality (non-CSM) for all patients. Additionally, competing risks regression (Fine-Gray) was implemented to evaluate any differences. After propensity score matching (PSM), all the aforementioned analyses were repeated. After the inverse probability of treatment weighting (IPTW), we repeated Kaplan–Meier methods on OS and CSS, and performed multivariable Cox regression analysis to assess OM in cryotherapy versus RT. Sensitivity analyses were conducted by excluding patients who died of cardiovascular disease. ResultsAfter applying 1:4 PSM to the cryotherapy group with the RT group, the resulting RT cohort consisted of 3,736 patients who were matched with 934 patients in the cryotherapy cohort. The 5‐year OS and cumulative CSM rates for PS-matched groups (N = 4670) receiving cryotherapy (N = 934) or RT (N = 3736) were 89% versus 91.8%, 0.65% versus 0.57, respectively. Multivariable Cox regression analysis demonstrated that cryotherapy was associated with a poorer OS outcome compared to RT (hazard ratio [HR] 1.29, 95% confidence interval [CI]: 1.07-1.55, p < .01). Multivariate competing risk regression analysis revealed that both treatments were not associated with CSS, with HR = 1.07 (95% CI: 0.55-2.08, p = .85). IPTW-adjusted analyses showed that the 5-years OS rates were 89.6% versus 91.8% for cryotherapy versus RT, respectively. Multivariate regression analysis for OS demonstrated that cryotherapy was more likely to have inferior OS in comparison to RT (HR = 1.30; 95%CI: 1.09-1.54; p < .01). The outcome of sensitivity analyses indicates that there was no significant difference in OS and CSS between the 2 groups. ConclusionFor low- and intermediate-risk PCa patients treated by cryotherapy or RT, we could not demonstrate a survival difference. Cryotherapy may be a feasible option as a viable alternative to traditional radiation therapy.

Virtual reality-assisted distraction during transcatheter aortic valve implantation under local anaesthesia: A randomised study

BackgroundA minimal approach, using local anaesthesia alone, has been advocated to promote faster transcatheter aortic valve replacement (TAVR) procedures in intermediate-risk patients. Pre- and periprocedural anxiety and pain remain a concern. Virtual reality (VR) is a form of non-pharmacological distraction that can potentially modulate pain and anxiety. This randomised study explored whether VR reduces pain and anxiety during TAVR without sedation and compared the effects of VR with those of standard care. Methods and resultsBetween June 2022 and March 2023, 207 patients underwent transfemoral TAVR (TF-TAVR). Of these, 117 (56.5%) patients were willing to participate in the study and met the educational background and mental status criteria for assessment. Fifty-nine patients underwent TF-TAVR with VR glasses (VR group). Fifty-eight patients underwent standard TF-TAVR without VR (control group; CG). Post-interventional anxiety scores (STAI-S) (31.5 ± 13.4 vs. 38.5 ± 19.2, p = 0.02) and the perceived duration of the procedure (60.1 ± 32.3 vs. 73.0 ± 32.4, p = 0.04) were lower in the VR than in the CG. Procedure time, pain, and anxiety scores (visual analogue scale) were similar between the groups. The complication rate was low and not associated with VR. Post-interventional delirium occurred in nine patients, and was similar between the groups (VR: 4 [6.8%] vs. CG: 5 [8.6%], p = 0.71). No periprocedural strokes were observed. ConclusionVR for TAVR is feasible and safe and expands the non-drug spectrum of therapy for anxiety and pain in patients undergoing TAVR with a minimalistic approach.

Comparison of outcomes for patients with acute myeloid leukemia undergoing haploidentical stem cell transplantation in first and second complete remission.

There was no consensus on whether prognostic advantages existed when transplant conducted at first complete remission (CR1) stage than at second complete remission (CR2) stage for patients with AML who received haploidentical hematological stem cell transplantation (haplo-HSCT). In 768 consecutive AML patients who received haplo-HSCT from January 2014 to December 2017, a 1:2 ratio matched-pair analysis was performed, 69 patients who in CR2 group and 138 CR1 patients were enrolled. Hematopoietic recovery, graft versus host disease (GVHD), relapse, transplant related mortality (TRM), disease-free survival (DFS) and overall survival (OS) were compared in two groups, and further evaluated in low-, intermediate-, and high-risk subgroups. The cumulative incidences of 30-day myeloid recovery and 90-day platelet recovery were comparable in CR1 and CR2 groups. The cumulative incidences of grade II-IV and grade III-IV aGVHD were not significantly different. The cumulative incidences of relapse at 3-year and 5-year in these two groups were 12.4% versus 11.6% (P = 0.880) and 12.4% versus 17.5% (P = 0.322). The cumulative incidences of TRM at 3-year and 5-year were both 10.9% versus 23.2% (P = 0.019). The probability of DFS at 3-year and 5-year were 76.7% versus 65.2% (P = 0.029) and 76.7% versus 59.3% (P = 0.009). The probability of OS at 3-year and 5-year were 81.8% versus 68.1% (P = 0.026) and 76.7% versus 59.3% (P = 0.026). In the intermediate-risk group, TRM was lower in CR1 group, DFS and OS of CR1 group were superior to CR2 group. In conclusion, haplo-HSCT at CR1 stage was of better prognosis for intermediate-risk AML patients than at CR2 stage.

Current evidence for moderate and ultra-hypofractionated radiation therapy in prostate cancer: a summary of the results from phase 3 randomised trials.

A low α/β ratio for prostate cancer (PCa) compared to surrounding normal tissue theoretically implies therapeutical advantages with hypofractionated treatment. Data from large randomised control trials (RCTs) comparing moderate hypofractionated (MHRT, 2.4-3.4 Gray/fraction (Gy/fx)) and ultra-hypofractionated (UHRT, >5 Gy/fx) with conventionally fractionated radiation therapy (CFRT, 1.8-2 Gy/fx) and the possible clinical implications have been reviewed. We searched PubMed, Cochrane and Scopus for RCT comparing MHRT/UHRT with CFRT treatment of locally and/or locally advanced (N0M0) PCa. We found six RCTs, which compared different radiation therapy regimes. Tumour control and acute and late toxicities are reported. MHRT was non-inferior to CFRT for intermediate-risk PCa, non-inferior for low-risk PCa and not superior in terms of tumour control for high-risk PCa. Acute toxicity rates were increased compared to CFRT, especially an increase in acute gastrointestinal adverse effects was seen. Late toxicity related to MHRT seems to be comparable. UHRT was non-inferior in terms of tumour control in one RCT, with increased acute toxicity, but with comparable late toxicity. One trial, however, indicated increased late toxicity rates with UHRT. MHRT delivers similar therapeutic outcomes compared to CFRT in terms of tumour control and late toxicity for intermediate-risk PCa patients. Slightly more acute transient toxicity could be tolerated in favour of a shorter treatment course. UHRT should be regarded as an optional treatment for patients with low- and intermediate-risk disease applied at experienced centres in concordance with international and national guidelines.
