Stereotactic radiotherapy for patients with bone metastases: a selected group with low rate of radiation treatment during the last month of life?

BackgroundComplex high-precision radiotherapy, such as stereotactic body radiotherapy (SBRT), should only be offered to patients with sufficiently long survival. In the context of bone metastases radiotherapy, low rates of treatment close to the end of life, e.g. last 30 days (RT30), may serve as a quality of care indicator. While traditional, pain-relieving short-course regimens have been studied comprehensively, real-world SBRT results are still limited.MethodsRetrospective analysis (2010–2023, n = 1117 episodes) of patients with bone metastases treated with traditional single-fraction (8 Gy × 1) or multi-fraction regimens (often 4 Gy × 5 or 3 Gy × 10) compared to stereotactic single-fraction (12–16 Gy × 1) or multi-fraction regimens.ResultsExcept for gender, almost all baseline variables were uneven distributed. Failure to complete fractionated radiotherapy was uncommon in the stereotactic (4%) and non-stereotactic group (3%), p = 1.0. With regard to RT30, relevant differences emerged (19% for 8-Gy single-fraction versus 0% for stereotactic single-fraction, p = 0.01). The corresponding figures were 11% for multi-fraction non-stereotactic and 2% for multi-fraction stereotactic, p = 0.08. Median overall survival was shortest after 8-Gy single-fraction irradiation (4.2 months) and longest after stereotactic multi-fraction treatment (13.9 months). Neither stereotactic radiotherapy nor multi-fraction treatment improved survival in multivariate Cox regression analysis. Factors significantly associated with longer survival included better performance status, lower LabBM score (5 standard blood test results), stable disease outside of irradiated area(s), metachronous distant metastases, longer time interval from metastatic disease to bone irradiation, and outpatient status.ConclusionThe implementation of SBRT for selected patients has resulted in low rates of non-completion and RT30. Optimal selection criteria remain to be determined, but in current clinical practice we exclude patients with poor performance status, unfavorable blood test results (high LabBM score) and progressive disease sites not amenable to SBRT. Established, guideline-endorsed short-course regimens, especially 8-Gy single-fraction treatment, continue to represent an important palliative approach.

Case Series: EGFR and ROS-1 Co-Occurrence in Advanced Non–Small Cell Lung Cancer

ABSTRACT Non–small cell lung cancer (NSCLC) is a heterogeneous disease with diverse molecular alterations. Two of the most common genetic abnormalities found in advanced NSCLC are mutations in the epidermal growth factor receptor (EGFR) and rearrangements in the ROS proto-oncogene 1 (ROS-1). Although these two alterations are typically mutually exclusive, there have been reports of their co-occurrence in a small subset of NSCLC patients. The discovery of this comutation has recently become apparent due to the increased use of more sensitive whole genome sequencing. We share our experience with two cases of coexisting EGFR and ROS-1 alterations. The first case is a 60-year-old man diagnosed with advanced adenocarcinoma of the lung with metastasis to bone and left adrenal gland. The second case is a 49-year-old woman diagnosed with stage IV lung adenocarcinoma with metastasis to the contralateral lung and diffuse abdominal lymphadenopathy. The first case was treated with osimertinib, and currently has had a stable disease on this medication for more than 3 years. The second case had a short interval of stable disease on osimertinib; then she developed progressive disease with poor response to anti–ROS-1 therapy. We believe patients with advanced NSCLC may have a higher incidence of coalterations, especially in the areas of the world with higher EGFR mutations and in the era of higher usage of whole genome sequencing. The presence of comutations will allow for a good long-term response to anti-EGFR therapy. This highlights the importance of the use of next-generation sequencing whenever possible and considers variant allele frequency as a factor in directing the therapy. There are many other unanswered questions, such as the best treatment sequencing or even the combined targeted therapy approach. This case series may add some information to the current literature.

Prospective study of the real impact of fusion centered genomic assays in patient management in a national collaborative group: the GETHI-XX-16 study.

Precision medicine represents a paradigm shift in oncology. Access to genetic testing and targeted therapies is frequently limited. Assays based on DNA sequencing can miss druggable alterations. We aimed to determine the impact of a free access program to RNA tests in patient management. We designed a multicenter prospective observational study within the Spanish National Group for Translational Oncology and Rare and Orphan Tumors (GETTHI). Eligible patients were adults with solid cancers that had progressed on standard therapies. Tumor samples were analyzed using two RNA sequencing assays (Trailblaze PharosTM and Archer FusionPlex Solid TumorTM). A central committee evaluated the actionability of genetic alterations and reported the findings to attending physicians, who made the final clinical management decisions. Between November 2016 and April 2019, 395 patients with 41 different tumors across 30 hospitals were included. Molecular analysis revealed actionable genetic alterations in 57 individuals (14.4%). Targeted therapies were advised for 23 and seven received a matched targeted therapy: two lung cancers (EML4-ALK and CD74-ROS1 fusion), three glioblastomas (EGFR point mutations), one oligodendroglioma (FGFR3-TACC3 fusion) and a prostate cancer (SND1-BRAF fusion). The outcomes included two tumor responses, one disease stabilization, one early withdrawal due to toxicity, one progression, and one unknown. Despite the growing knowledge of cancer biology and its translation to drug development, the overall impact of personalized treatments remains low. Access to comprehensive molecular tests covering properly all known actionable alterations and programs for a wide access to targeted therapies seem to be critical steps.

Aerobic exercise alleviates statin-induced PCSK9 upregulation by increasing epoxyeicosatrienoic acid levels through the FoxO3a-Sirt6 axis

BackgroundStatins are the cornerstone of low-density lipoprotein cholesterol (LDL-C)-lowering therapy; however, the therapeutic efficacy of statins in countering atherosclerotic cardiovascular disease (ASCVD) is compromised by the concurrent elevation of proprotein convertase subtilisin/kexin type 9 (PCSK9), a pivotal molecule that increases LDL-C levels. Aerobic exercise lowers PCSK9 levels, but the underlying mechanism remains unclear. Therefore, we investigated how aerobic exercise can ameliorate statin-induced increases in PCSK9 levels. MethodsThree-week-old male American Institute of Cancer Research (ICR) mice were fed a high-fat-cholesterol diet (HFD) for 12 weeks and then administered atorvastatin alone or atorvastatin combined with aerobic exercise (Statin+Ex). Moreover, a total of 165 participants with stable coronary heart disease (CHD) enrolled at the inpatient and outpatient departments of the Second Xiangya Hospital of Central South University from January 2018 to July 2020 were randomized into the Statin group (male/female = 51/33) and Statin+Ex group (male/female = 52/29). Patients in the Statin+Ex group underwent treadmill exercise of 45–60 min/day for 7 days. ResultsAerobic exercise effectively alleviated statin-induced PCSK9 upregulation in human patients with CHD and hypercholesterolemic ICR mice (all p< 0.05). Mechanistically, our findings revealed that aerobic exercise induced elevated epoxyeicosatrienoic acids (EETs) plasma levels while concurrently reducing the activity of soluble epoxide hydrolase (sEH) (all p < 0.05), an enzyme responsible for EETs degradation. Further, EETs significantly suppressed PCSK9 expression, subsequently reducing the LDL-C levels (all p < 0.05); this effect was mediated via the activation of the Forkhead box O3a-Silent mating type information regulation 2 homolog 6 (FoxO3a-Sirt6) axis, with no impact on the Sterol Regulatory Element Binding Protein 2 and 3-hydroxy-3-methylglutaryl-CoA reductase(SREBP2-HMGCR) pathway. ConclusionOur study sheds light on the paradigm of "Exercise is Medicine", providing evidence to support the use of statins combined with exercise in reducing LDL-C levels, and unveils potential avenues for clinical applications of sEH inhibitors, presenting novel prospects for therapeutic interventions in ASCVD.

A protocol for a Japanese prospective cohort evaluating the features of patients with uncontrolled asthma achieving clinical remission: J-CIRCLE

BackgroundIncreasing expectations that biologics can be used as disease-modifying agents have introduced the concept of clinical remission (CR) in managements of severe asthma. Given the clinical relevance of computed tomography (CT) and blood biomarkers, we hypothesized that further refinement of CR criteria as well as incorporation of CT and blood biomarkers as indicators for structural and biological remission (SR, BR) would enable predicting long-term disease stability in patients with severe asthma treated with biologics. MethodsThis Japanese multicenter prospective observational cohort will enroll patients with severe asthma who will start a new biologic (including a change from another biologic). The enrolled patients will be longitudinally followed up for 3 years. At enrollment, patients will undergo postbronchodilator spirometry, blood tests, fractional exhaled nitric oxide, chest and sinus CT, and patient-reported outcome questionnaires. Follow-up examinations will be performed at 1, 3, 6, 12, 24, and 36 months. The rates of CR resulting from different criteria after 1 year of treatment with biologics will be compared, and factors associated with long-term disease stability after 3 years of biologic treatments will be identified. DiscussionThis multicenter study in Japan will provide data that will help establish more appropriate criteria for CR, structural remission, and biological remission to predict long-term disease stability in patients with severe asthma who receive biologic therapy. Ethics and disseminationThe study was approved by the Ethics Committee of Kyoto University (No. R4419, approval date June 11th, 2024).

Abdominal B-Cell Lymphoma Mimicking Ovarian Cancer

A 54-year-old patient presented in our clinic with pressure in the upper abdomen, dyspnea and abdominal distension. The clinical examination showed pleural effusion, ascites and an enlarged axillary lymph node on the right side. In gynecological sonography ascites, an ovarian cyst and peritoneal carcinosis in the pouch of Douglas were detected, which were potentially indicative of ovarian cancer. A staging laparoscopy was performed to confirm the diagnosis of ovarian cancer and to evaluate operability. Intraoperatively white milky ascites, white-yellow marbling of the liver and white stipple bedding on the diaphragm and liver were detected. The ovaries and the fallopian tubes were tumorously enlarged. Biopsies were taken from the right fimbrial funnel, the liver around the falciform ligament and the diaphragm. Histology of all abdominal biopsies and the axillary lymph node revealed high lymphatic infiltration matching a stage III B-cell-lymphoma. The patient was transferred to the hemato-oncological department for further therapy. Six cycles of cytostatic therapy with R-CHOP (rituximab, cyclophosphamide, hydroxydaunorubicin, vincristine sulfate, prednisone) were initiated. The patient is doing well and in stable disease 6 months after completion of cytotoxic therapy. This case report presents a rare case of manifestation of an extra nodal B-cell-lymphoma with abdominal presentation that mimicked ovarian cancer.

Real-World Clinical Outcomes of Neoadjuvant Platinum-Based Chemotherapy with Nivolumab in Non-Small Cell Lung Cancer

Background: Lung cancer is among the most prevalent and serious forms of cancer, characterized by an allogenic phenotype that presents significant therapeutic challenges. Materials and Methods: We analyzed medical records from January 2022 to August 2023, focusing on individuals aged 18 and older diagnosed with resectable NSCLC who received neoadjuvant chemo-immunotherapy prior to surgical intervention. Results: The cohort comprised 56 patients, predominantly smokers (95%) and male (74%), with 80% presenting the disease at stage III. Of the participants, 44 underwent surgery, with 95% receiving lobar resection. Clinical assessments via PET-CT imaging revealed an 86% rate of response or disease stabilization, while pathological evaluations showed complete and major pathological responses in 61% of cases. Conclusions: This real-world data supports the safety and efficacy of incorporating immune checkpoint inhibitors in the neoadjuvant treatment of NSCLC, followed by surgical resection.

Liver Transplantation for Intrahepatic Cholangiocarcinoma After Chemotherapy and Radioembolization: An Intention-To-Treat Study

Liver transplantation (LT) is a potentially curative experimental treatment for unresectable intrahepatic cholangiocarcinoma (iCC). Pre-transplant downstaging may help defining tumor aggressiveness and drive patient selection. We report the preliminary results of LT for liver-limited unresectable iCC after sequential downstaging with systemic chemotherapy and radioembolization (SYS-TARE). In case of sustained disease stability after SYS-TARE, patients underwent surgical nodal sampling and, if negative, were listed for LT. In this study, 13 patients with unresectable iCC underwent downstaging with SYS-TARE. The median age was 70 years and 77% were female. All had single bulky lesions at diagnosis. After SYS-TARE, 9 (69%) dropped out: 3 due to progressive disease after TARE with no response to second-line, 4 due to extrahepatic disease development and 2 due to positive nodal disease at pre-listing abdominal exploration. The median OS after dropout was 11.5 months. Four (31%) were successfully listed and transplanted. At pathology, viable tumor ranged from 30% to less than 5%. All four patients are alive and disease-free at 73, 40, 12, and 8 months from LT. LT for unresectable iCC after downstaging with SYS-TARE appears to select suitable patients for LT, achieving optimal oncological outcomes in case of response to therapy and no lymphnodal spread.

Feasibility, Tolerability, and Preliminary Clinical Response of Fractionated Radiopharmaceutical Therapy with 213Bi-FAPI-46: Pilot Experience in Patients with End-Stage, Progressive Metastatic Tumors.

Radiopharmaceutical therapies (RPTs) based on fibroblast activation protein (FAP) and FAP inhibitors (FAPIs) are a new option for progressive metastatic cancer in patients pretreated multiple times. To date, published in-human data refer to initial experiences with β-emitting 90Y- and 177Lu-based RPT. However, the short tumor retention time of FAPI ligands is considered a major limitation of FAPI RPT. Therefore, fractionated FAPI RPT with 213Bi, an α-emitter with a half-life of 46 min, appears to be a promising FAPI RPT regimen. Here, we report on our initial experiences with regard to the feasibility, tolerability, and response of fractionated 213Bi-FAPI-46 RPT. Methods: Six patients (4 women and 2 men) with progressive metastatic solid tumors (3 colon cancer, 1 anal cancer, 1 breast cancer, and 1 prostate cancer) aged 16-77 y were treated with a mean of 1,609 MBq of 213Bi-FAPI-46, fractionated into 53 single applications (range, 5-12 RPT applications per patient; mean, 8.8 applications) over a period of up to 107 h per patient. Of the 6 patients, 4 patients received adjuvant treatment with pembrolizumab. 18F-FDG (4 patients) and 68Ga-FAPI-46 (5 patients) PET/CT scans were performed before and after RPT. PET images were assessed visually and by calculating total lesion glycolysis and total lesion FAPI. Results: RPT with 213Bi-FAPI-46 was well tolerated without adverse side effects. In terms of visual response assessment, there was 1 partial response (16.7%), 1 patient with stable disease (16.7%), and 4 patients with progressive disease (66.7%). Concordantly, total lesion glycolysis and total lesion FAPI were decreased in the responding patient (not applicable and -24.3%, respectively), slightly decreased in the patient with stable disease (-10.6% and -5.9%, respectively), and increased in the 4 patients with progression (mean, +104.4% and +321.3%, respectively). Conclusion: Fractionated FAPI RPT with the short-half-life α-emitter 213Bi-FAPI-46 is a promising approach that matches the pharmacokinetics of FAPI-46 better than the 177Lu- or 90Y-labeled compounds. In this pilot project, fractionated RPT with 213Bi-FAPI-46 showed good clinical tolerability and even led to regressive or stable disease in the short term in 2 of 6 patients. Further studies with larger patient cohorts are required to evaluate the actual efficacy and long-term effects of this variant of FAPI RPT.

Patient-initiated follow-up supported by asynchronous telemedicine versus usual care in spondyloarthritis (TeleSpA-study): a randomised controlled trial of clinical and cost-effectiveness.

With rising health-care expenditures and workforce shortages, sustainable alternatives to traditional outpatient follow-up strategies are required to optimise care efficiency. We aimed to investigate the cost-effectiveness and clinical effectiveness of patient-initiated follow-up (PIFU) supported by asynchronous telemedicine for patients with spondyloarthritis compared with usual care in daily practice. TeleSpA was a multicentre, pragmatic, open-label, randomised controlled trial. Patients with spondyloarthritis and stable disease were randomly assigned (1:1) to either the PIFU and asynchronous telemedicine group or usual care group. All patients received a scheduled outpatient visit at baseline and after 1 year. Patients were monitored remotely at 6 months (PIFU and asynchronous telemedicine) or at the discretion of the treating rheumatologist (usual care). The primary outcome was the number of rheumatology visits within a 1-year period. A trial-based 1-year health-economic evaluation from a Dutch health-care perspective (only including health-care costs) and societal perspective (also including travel costs and work productivity losses), per the Dutch guidelines was used to estimate cost-effectiveness. The safety analysis was done in the intention-to-treat population and was based on spontaneous reports of adverse events and serious adverse events or as observed by the research team. The primary analysis was in the intention-to-treat population. Individuals with relevant lived experience were involved in the study design. This trial was registered with the Dutch National Trial Register (NL71041.068.19) and ClinicalTrials.gov (NCT04673825) and is completed. Between Dec 2, 2020, and June 20, 2022, 200 patients were randomly assigned to PIFU and asynchronous telemedicine (n=100) or usual care (n=100). 79 (40%) of 200 participants were women, 121 (60%) were men, and the mean age was 55·0 years (SD 11·9). After 1 year, the mean number of rheumatology visits was 1·9 (SD 1·5) for the PIFU and asynchronous telemedicine group and 2·6 (1·3) in the usual care group (mean difference -0·7 [95% CI -1·0 to -0·3]; 25·4% reduction; p<0·0001). PIFU and asynchronous telemedicine was cost-effective from a health-care perspective, saving health-care costs (-€180 [95% CI -921 to 560]) without a loss in quality-adjusted life-years (0·004 [95 % CI -0·022 to 0·030]). Seven non-trial-related adverse events occurred in the PIFU and asynchronous telemedicine group and eight in usual care group (including one death). PIFU and asynchronous telemedicine resulted in significant and clinically meaningful reductions in rheumatology visits. This was not at the expense of health outcomes and saved health-care costs.

Postradiotherapy Response Assessment Using 18F-FDG PET/CT in Salivary Gland Carcinoma-A Multicenter Study.

This multicenter study investigates the efficacy of 18F-FDG PET/CT in postradiotherapy (post-RT) response evaluation in salivary gland carcinoma (SGC). We retrospectively reviewed 115 SGC patients who underwent definitive or adjuvant RT followed by 18F-FDG PET/CT between 2004 and 2021. Most tumors were parotid gland malignancies (50%). The most common histological subtypes were adenoid cystic (29%) and mucoepidermoid carcinomas (18%). The median follow-up was 65 months. Post-RT anatomic images (CT/MRI) revealed complete response (CR) in 51 patients (44%). Among 53 patients with partial response or stable disease, only 17 (32%) patients experienced locoregional recurrence, with a 5-year locoregional control rate of 69%. Post-RT 18F-FDG PET/CT documented metabolic CR in 81 patients (70%). Metabolic complete responders had significantly higher 5-year locoregional control (90% vs 43%), distant metastasis-free survival (80% vs 48%), progression-free survival (76% vs 24%), and overall survival rates (89% vs 42%) compared with non-complete responders (all P < 0.001), as confirmed in both univariate and multivariate analyses. It identified additional viable tumors in 18 cases (16%) and facilitated salvage local therapies in 7 patients (6%). The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of post-RT 18F-FDG PET/CT were 63%, 91%, 70%, 88%, and 84%, respectively, in predicting locoregional recurrence. 18F-FDG PET/CT showed significantly higher sensitivity (88% vs 36%, P = 0.011) in tumors with pre-RT SUVmax ≥7.39 compared with those with SUVmax <7.39. Post-RT 18F-FDG PET/CT demonstrates high negative predictive value and specificity, with metabolic CR predicting excellent outcomes. Additionally, it exhibits higher sensitivity for high-SUVmax SGC, facilitating early detection of viable tumors.

Efficacy and safety of lenvatinib and pembrolizumab as first-line treatment for advanced renal cell carcinoma patients: real-world experience in Japan.

Combined treatment with lenvatinib and pembrolizumab is currently regarded as one of the standard first-line therapies for advanced renal cell carcinoma (aRCC) patients. The objective of this study was to assess the efficacy and safety of this combined regimen in treatment-naïve Japanese aRCC patients. This study included a total of 50 consecutive aRCC patients receiving combined lenvatinib plus pembrolizumab in routine clinical practice in Japan, and comprehensively analyzed clinical outcomes of this treatment. Of these 50, 7 (14.0%), 23 (46.0%) and 20 (40.0%) were classified into favorable, intermediate and poor risk groups, respectively, according to the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) system. Responses to this combined therapy in the 50 patients were as follows: complete response, 7 (14.0%); partial response, 26 (52.0%); stable disease, 15 (30%) and progressive disease, 2 (4%); thus, the objective response rate (ORR) was 66%. ORRs in favorable, intermediate and poor risk groups were 57.1, 69.6 and 65.0%, respectively. During the observation period, disease progression and death occurred in 14 (28.0%) and 6 (12.0%) patients, respectively, and neither the median PFS nor OS was reached. Adverse events and those corresponding to grade ≥ 3 were observed in all (100%) and 33 (66.0%) patients, respectively. To our knowledge, this is the first study focusing on real-world outcomes of lenvatinib and pembrolizumab for treatment-naïve aRCC patients, showing that the efficacy and safety of this combined regimen are similar to those noted in randomized clinical trial.

Diagnostic performance of fast brain MRI compared to routine clinical MRI in patients with glioma grade 3 and 4 -a pilot study.

EPIMix is a fast brain MRI technique not previously investigated in patients with glioma grades 3 and 4. This pilot study aimed to investigate the diagnostic performance of EPIMix in the radiological treatment evaluation of adult patients with glioma grades 3 and 4 compared to routine clinical MRI (rcMRI). Patients with glioma grades 3 and 4 investigated with rcMRI and EPIMix were retrospectively included in the study. Three readers (R1-3) participated in the radiological assessment applying Response Assessment for Neuro-oncology Criteria (RANO 2.0), of which two (R1-2) independently evaluated EPIMix and later rcMRI by measuring contrast-enhancing and non-contrastenhancing tumor regions at each follow-up. For cases with discrepant evaluations, an unblinded side-by-side (EPIMix and rcMRI) reading was performed together with a third reader (R3). Comparisons between methods (EPIMix vs. rcMRI) were performed using Weighted Cohen's kappa. The sensitivity and specificity to detect tumor progression (PD) on a follow-up scan were calculated for EPIMix compared to rcMRI with receiver operating characteristic (ROC) curves to assess the area under the curve (AUC). In 35 patients (mean age 53, 31% females), a total of 93 MRIs encompassing 58 follow-up investigations showed PD at blinded reading in 33% of EPIMix (19/58, R1-2), while in 31% (18/58 exams, R1), and 34% (20/58 exams, R2) of rcMRI. An almost perfect agreement for tumor category assessment was found between EPIMix and rcMRI (EPIMixR1 vs. rcMRIR1 ϰ= 0.96; EPIMixR2 vs. rcMRIR2 ϰ= 0.89). The sensitivity for EPIMix to detect PD was 1.00 (0.81-1.00) for R1 and 0.90 (0.68-0.99) for R2, while the specificity was 0.97 (0.86-1.00) for R1-2. The AUC for PD was 0.99 for R1 (EPIMixR1 vs. rcMRIR1) and 0.94 for R2 (EPIMixR2 vs. rcMRIR2), DeLong's test AUCR1 vs. AUCR2 p=0.20 (R1-2). In this pilot study, EPIMix was used as a fast MRI alternative for treatment evaluation of patients with glioma grades 3 and 4, with high, but slightly lower diagnostic performance than rcMRI. CR = complete response; EPIMix = multi-contrast echo-planar imaging-based technique; PD = progressive disease; PR = partial response; RANO = response assessment in neuro-oncology; R1 = reader 1; R2 = reader 2; R3 = reader 3; rcMRI = routine clinical MRI; SD = stable disease.

Cross-Sectional Descriptive Study of the Utility of Dermoscopy in Assessing the Activity and Stability of Vitiligo

Introduction: Dermoscopy is an important noninvasive tool that helps to determine the stability and activity of vitiligo. Various dermoscopic findings help classify the disease as stable or unstable. This is important for the management of the disease, as surgical management requires disease stability. Objectives: We aimed to describe the dermoscopic findings in vitiligo and to assess the frequency of various dermoscopic findings in stable and unstable vitiligo. Methods: This was a hospital-based, cross-sectional, descriptive study of 100 vitiligo patients and various dermoscopic findings. Results are expressed as percentages. Results: The most common dermoscopic findings in stable vitiligo patches were sharp border, marginal and perifollicular pigmentation, and reticulate pigment network. Findings such as polka dot appearance, starburst appearance, comet tail, and satellite lesions were seen in unstable vitiligo patches. Conclusions: Dermoscopy is extremely helpful in determining the stability of vitiligo patches.

Characterizing Nonculprit Lesions and Perivascular Adipose Tissue of Patients Following Acute Myocardial Infarction Using Coronary Computed Tomography Angiography: A Comparative Study.

The comparison of coronary computed tomography angiography plaques and perivascular adipose tissue (PVAT) between patients with acute myocardial infarction (AMI) posttreatment and patients with stable coronary artery disease is poorly understood. Our objective was to evaluate the differences in coronary computed tomography angiography-quantified plaque and PVAT characteristics in patients post-AMI and identify signs of residual inflammation. We analyzed 205 patients (age, 59.77±9.24 years; 92.20% men) with AMI ≤1 month and matched them with 205 patients with stable coronary artery disease (age, 60.52±10.04 years; 90.24% men) based on age, sex, and cardiovascular risk factors. Coronary computed tomography angiography scans were assessed for nonculprit plaque and vessel characteristics, plaque volumes by composition, high-risk plaques, and PVAT mean attenuation. Both patient groups exhibited similar noncalcified plaque volumes (383.35±313.23 versus 378.63±426.25 mm3, P=0.899). However, multivariable analysis revealed that patients post-AMI had a greater patient-wise noncalcified plaque volume ratio (estimate, 0.089 [95% CI, 0.053-0.125], P<0.001), largely attributed to a higher fibrofatty and necrotic core volume ratio, along with higher peri-lesion PVAT mean attenuation (estimate, 3.968 [95% CI, 2.556-5.379], P<0.001). When adjusted for vessel length, patients post-AMI had more high-risk plaques (estimate, 0.417 [95% CI, 0.298-0.536], P<0.001) per patient. Patients post-AMI displayed heightened noncalcified plaque components, largely due to fibrofatty and necrotic core content, more high-risk plaques, and increased PVAT mean attenuation on a per-patient level, highlighting the necessity for refined risk assessment in patients with AMI after treatment.

The efficacy and safety of anlotinib combined with chemotherapy in treatment of advanced soft tissue sarcoma

BackgroundTo evaluate the efficacy and safety of anlotinib combined with chemotherapy in the treatment of advanced soft tissue sarcoma (STS).MethodsA total of 14 patients with advanced STS consisting of 4 liposarcoma, 3 undifferentiated polymorphous sarcoma, 2 synovial sarcoma, 1 Extraosseous ewing sarcoma, 1 spindle cell sarcoma, 1 Sarcomatoid malignant mesothelioma, 1 hemangiosarcoma, and 1 fibrosarcoma, were treated with anlotinib plus chemotherapy. The anlotinib was combined with chemotherapy as the first-line treatment in 13 patients, and as second-line treatment in 1 patient. Chemotherapy regimens were based on anthracyclines and ifosfamide, and other drugs included paclitaxel, and so on. Efficacy and safety were evaluated every 2 treatment cycles.ResultsAccording to the stage of AJCC, 9 patients were stage III and 5 patients were stage IV. The average cycle of treatment is 3.86. Among the 14 patients, 2 cases had received surgical treatment after neoadjuvant chemothrapy, 5 cases had partial response (PR), 7 cases had stable disease (SD), and 2 cases had progressive disease (PD). The overall response rate (ORR) was 35.7% (5/14). Patients who had not underwent surgical treatment were with a disease control rate (DCR) of 83.3% (10/12). The median progression free survival (PFS) was 8.25 months. The common treatment-related adverse effects included bone marrow suppression, nausea, vomiting and hypertension. Three patients had severe adverse effect, which was febrile neutropenia. No treatment-related death was found.ConclusionsAnlotinib combined with chemotherapy in the treatment of STS is effective and tolerable, which is a promising strategy. It is worthy of further clinical research.

The role of beta blockers in the treatment of cardiovascular diseases

Beta-blockers are used to treat various cardiovascular diseases, including hypertension and chronic heart failure. They act by suppressing the effects of catecholamines through various pathways and affect heart rate, strength, and renin release, providing antihypertensive and anti-ischemic effects. The individual effects of various drugs on clinical outcomes in this group were determined according to characteristics of the patient, underlying disease, and type of beta-blocker used. In recent years, beta-blockers have faced a serious obstacle when new guidelines on hypertension suggest their use as second-line therapy after angiotensin converting enzyme inhibitors, angiotensin receptor blockers and slow calcium channel blockers in the absence of clear indications. In fact, these recommendations were based on meta-analyses that showed that beta-blockers have fewer beneficial effects on overall mortality, cardiovascular events, and brain stroke. In addition, according to currently available data, the appointment of beta-blockers for diseases such as heart failure with preserved ejection fraction and stable coronary heart disease can cause more harm than good outcomes. Bisoprolol is a beta-blocker with the highest selectivity for beta1-adrenergic receptors, which determines the rare frequency of side effects that develop because of its use. This review presents current data on the use of beta-blockers for treating cardiovascular diseases, with an emphasis on the use of bisoprolol.

The diagnostic role of myocardial work indices in stable coronary disease - global wasted work as a novel important non-invasive parameter?

Abstract Introduction Although the non-invasive diagnostic tools for stable coronary artery disease (CAD) have developed significantly over the past years, there is no resting parameter available to recognize functionally significant CAD. The role of the novel myocardial work index (myocardial work index - MWI) calculated by the pressure-strain loop created with the help of speckle-tracking analysis and blood pressure measurement in the diagnosis of ischemic heart disease is not yet fully clarified. In our research, we examined the parameters of myocardial work analysis in stable coronary disease patients. Purpose Clarification of the diagnostic role of the myocardial work analysis, in patients with stable coronary artery disease. Methods In our prospective, single-center study, we examined 13 patients who had at least moderate stenosis (≥50%) in one main coronary branch detected on coronary CTA. A fractional flow reserve (FFR) test was performed for functional coronary assessment. Based on this measurement, we divided our patients into FFRneg (FFR value&amp;gt;0.8) and FFRpos groups. Echocardiography was performed before coronary angiography in all patients. In addition to the standard echocardiographic parameters, global myocardial work index (GWI), global constructive work (GCW) and global wasted work (GWW) were calculated. In the case of the FFRpos group, we performed the above examination both before and after revascularization (2 months). Results Our results show that neither the standard parameters (GLS, EF), nor the GWI and GCW showed any difference between the FFRpos and FFRneg groups. However, there was a significant difference regarding GWW (172.3±21.8 FFRneg vs. 258.2±38.4 FFRpos, p=0.048) at baseline. In the case of the FFRpos group, the analysis of our data showed that there was no significant difference in EF, GLS, GWI and GWE parameters before and after revascularization. However, global wasted work (GWW) showed a significant improvement after revascularization (preGWW 258.2±38.4 vs. postGWW 139.5±14.5, p=0.041). NT-proBNP levels were normal in our patient population and we could not detect. Conclusion Based on our results, the GWW may be suitable for non-invasive assessment of the functional significance of stable coronary disease, as it showed a significant difference in the case of functionally significant and non-significant stenosis and improved after revascularization in patients with single-vessel CAD.

Body mass index and clinical outcomes in patients with diabetes and stable coronary artery disease in THEMIS

Abstract Background Physiologic changes due to extremes of body weight may affect the efficacy and tolerability of antiplatelet treatment. However, it remains unclear whether the risks and benefits of intensified antiplatelet therapy among patients with diabetes and stable coronary artery disease (CAD) are affected by body mass index (BMI). Purpose To assess the relationship between baseline BMI and major adverse cardiovascular (CV) events, and to determine if the effects of ticagrelor vs. placebo varied across the BMI spectrum, in patients with diabetes and stable CAD. Methods THEMIS was a randomized, controlled trial of 19,220 individuals aged ≥50 years with type 2 diabetes and stable CAD, randomly allocated to ticagrelor or placebo on top of aspirin. Patients with a prior myocardial infarction (MI) or stroke, or already on dual antiplatelet therapy, were excluded. The primary efficacy outcome was a composite of CV death, MI, or stroke. The primary safety outcome was TIMI major bleeding. We examined prognostic implications of BMI using 1) restricted cubic splines for the overall trends with outcomes; 2) Cox regression models with predefined BMI intervals (&amp;lt;25 kg/m2, 25-29.9 kg/m2, and ≥30 kg/m2) adjusted for demographic, clinical, and laboratory variables; and 3) Cox regression models for the effects of ticagrelor vs. placebo on outcomes across the spectrum of BMI values (test for interaction). A two-sided P-value &amp;lt;0.01 was considered statistically significant to control the overall chance of type I errors. Results BMI was available in 19,202 (99.9%) participants, with a median of 29 kg/m2 (interquartile range: 26-33). A total of 3352 (17.5%) individuals had a BMI &amp;lt;25 kg/m2, 7644 (39.8%) had a BMI 25-29.9 kg/m2, and 8206 (42.7%) had a BMI ≥30 kg/m2. Median follow-up was 39.9 months (range 0-57), with 1554 primary efficacy events and 306 primary safety events occurring over the course of the study. BMI was not associated with the primary efficacy or safety outcome, or with their individual components. However, BMI was significantly associated with hospitalization for heart failure (HHF) (BMI &amp;lt;25 kg/m2: reference; hazard ratio [HR] for BMI 25-29.9 kg/m2: 1.07, 95% confidence interval [CI], 0.82 to 1.40; HR for BMI ≥30 kg/m2: 1.41, 95% CI, 1.07 to 1.84) and with the composite of HHF or CV death (comparable estimates) after multivariable adjustment (Figure). BMI was also significantly, positively associated with serious adverse events (BMI &amp;lt;25 kg/m2: reference; HR for BMI 25-29.9 kg/m2: 0.99, 95% CI, 0.93 to 1.06; HR for BMI ≥30 kg/m2: 1.20, 95% CI, 1.12 to 1.29). BMI did not modify the risks and benefits of ticagrelor vs. placebo. Conclusions BMI was independently associated with the risk of HHF and the composite of HHF or CV death, but not with other efficacy or safety outcomes, in patients with stable CAD and type 2 diabetes. Ticagrelor was of similar benefit on the primary efficacy outcome vs. placebo across the full range of BMI.

The coronary angiography-derived index of microcirculatory resistance predicts perioperative myocardial injury in stable coronary artery disease patients undergoing PCI

Abstract Background Coronary microvascular dysfunction (CMD) assessed by the index of microcirculatory resistance (IMR) is associated with perioperative myocardial injury(PMI).The angiography-derived index of microcirculatory resistance (caIMR) is a novel and accurate alternative of IMR. Objective This study aims to evaluate the predictive value of caIMR on PMI in stable coronary artery disease (CAD) patients undergoing percutaneous coronary intervention (PCI). Methods Consecutive stable CAD patients undergoing elective PCI of a single lesion were recruited. caIMR were measured before and after revascularization.Total creatine kinase-MB (CK-MB) and high sensitivity Troponin T (hsTnT) levels were measured before and within 24 hours after PCI. Results A total of 65 patients were enrolled, twenty-six patients fulfilled the diagnostic criteria of PMI. Post-PCI caIMR values in the PMI group were significantly higher than those in the control group (27.02±3.70 vs. 15.91±3.43U, P&amp;lt;0.001). Pearson correlation analysis demonstrated that increased post-PCI caIMR values have a significant positive correlation with peak hsTnT (r = 0.803, P&amp;lt;0.001) and peak CK-MB (r = 0.512, P= 0.001). Multivariate logistic regression analysis showed the post-PCI caIMR was independent predictors of PMI(OR,1.731;95% CI:1.348-2.023; P&amp;lt;0.001).The ROC analysis suggested that the best cutoff value of post-PCI caIMR was 25.17U to diagnose PMI(AUC=0.951, sensitivity 88.5%, specificity 97.1%%). Conclusions The post-PCI caIMR can accurately predict PMI in stable CAD patients receiving elective PCI, supporting its use in clinical practice.
