  • Detection and localization of early- and late-stage cancers using platelet RNA
  • 2022
  • Ingår i: Cancer Cell. - : Elsevier. - 1535-6108 .- 1878-3686. ; 40:9, s. 999-1009.e6

    • Cancer patients benefit from early tumor detection since treatment outcomes are more favorable for less advanced cancers. Platelets are involved in cancer progression and are considered a promising biosource for cancer detection, as they alter their RNA content upon local and systemic cues. We show that tumor-educated platelet (TEP) RNA-based blood tests enable the detection of 18 cancer types. With 99% specificity in asymptomatic controls, thromboSeq correctly detected the presence of cancer in two-thirds of 1,096 blood samples from stage I–IV cancer patients and in half of 352 stage I–III tumors. Symptomatic controls, including inflammatory and cardiovascular diseases, and benign tumors had increased false-positive test results with an average specificity of 78%. Moreover, thromboSeq determined the tumor site of origin in five different tumor types correctly in over 80% of the cancer patients. These results highlight the potential properties of TEP-derived RNA panels to supplement current approaches for blood-based cancer screening.

  • Apertif: Phased array feeds for the Westerbork Synthesis Radio Telescope: System overview and performance characteristics
  • 2022
  • Ingår i: Astronomy and Astrophysics. - : EDP Sciences. - 0004-6361 .- 1432-0746. ; 658
  • Tidskriftsartikel (refereegranskat)abstract
    • We describe the APERture Tile In Focus (Apertif) system, a phased array feed (PAF) upgrade of the Westerbork Synthesis Radio Telescope that transforms this telescope into a high-sensitivity, wide-field-of-view L-band imaging and transient survey instrument. Using novel PAF technology, up to 40 partially overlapping beams are formed on the sky simultaneously, significantly increasing the survey speed of the telescope. With this upgraded instrument, an imaging survey covering an area of 2300 deg2 is being performed that will deliver both continuum and spectral line datasets, of which the first data have been publicly released. In addition, a time domain transient and pulsar survey covering 15 000 deg2 is in progress. An overview of the Apertif science drivers, hardware, and software of the upgraded telescope is presented, along with its key performance characteristics.

  • EAU-ESMO Consensus Statements on the Management of Advanced and Variant Bladder Cancer – An International Collaborative Multistakeholder Effort : Under the Auspices of the EAU-ESMO Guidelines Committees
  • 2020
  • Ingår i: European Urology. - : Elsevier. - 0302-2838 .- 1873-7560. ; 77:2, s. 223-250
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Although guidelines exist for advanced and variant bladder cancer management, evidence is limited/conflicting in some areas and the optimal approach remains controversial.OBJECTIVE: To bring together a large multidisciplinary group of experts to develop consensus statements on controversial topics in bladder cancer management.DESIGN: A steering committee compiled proposed statements regarding advanced and variant bladder cancer management which were assessed by 113 experts in a Delphi survey. Statements not reaching consensus were reviewed; those prioritised were revised by a panel of 45 experts prior to voting during a consensus conference.SETTING: Online Delphi survey and consensus conference.PARTICIPANTS: The European Association of Urology (EAU), the European Society for Medical Oncology (ESMO), experts in bladder cancer management.OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Statements were ranked by experts according to their level of agreement: 1-3 (disagree), 4-6 (equivocal), and 7-9 (agree). A priori (level 1) consensus was defined as ≥70% agreement and ≤15% disagreement, or vice versa. In the Delphi survey, a second analysis was restricted to stakeholder group(s) considered to have adequate expertise relating to each statement (to achieve level 2 consensus).RESULTS AND LIMITATIONS: Overall, 116 statements were included in the Delphi survey. Of these statements, 33 (28%) achieved level 1 consensus and 49 (42%) achieved level 1 or 2 consensus. At the consensus conference, 22 of 27 (81%) statements achieved consensus. These consensus statements provide further guidance across a broad range of topics, including the management of variant histologies, the role/limitations of prognostic biomarkers in clinical decision making, bladder preservation strategies, modern radiotherapy techniques, the management of oligometastatic disease, and the evolving role of checkpoint inhibitor therapy in metastatic disease.CONCLUSIONS: These consensus statements provide further guidance on controversial topics in advanced and variant bladder cancer management until a time when further evidence is available to guide our approach.PATIENT SUMMARY: This report summarises findings from an international, multistakeholder project organised by the EAU and ESMO. In this project, a steering committee identified areas of bladder cancer management where there is currently no good-quality evidence to guide treatment decisions. From this, they developed a series of proposed statements, 71 of which achieved consensus by a large group of experts in the field of bladder cancer. It is anticipated that these statements will provide further guidance to health care professionals and could help improve patient outcomes until a time when good-quality evidence is available.

  • Complete vs Culprit-Lesion-Only Revascularization for ST-Segment Elevation Myocardial Infarction A Systematic Review and Meta-analysis
  • 2020
  • Ingår i: JAMA cardiology. - : AMER MEDICAL ASSOC. - 2380-6583 .- 2380-6591. ; 5:8, s. 881-888
  • Forskningsöversikt (refereegranskat)abstract
    • IMPORTANCE Recently, the Complete vs Culprit-Only Revascularization to Treat Multi vessel Disease After Early PCI (percutaneous coronary intervention) for STEMI (ST-segment elevation myocardial infarction [MI]) (COMPLETE) trial showed that angiography-guided PCI of the nonculprit lesion with the goal of complete revascularization reduced cardiovascular (CV) death or new MI compared with PCI of the culprit lesion only in STEMI. Whether complete revascularization also reduces CV mortality is uncertain. Moreover, whether the association of complete revascularization with hard clinical outcomes is consistent when fractional flow reserve (FFR)- and angiography-guided strategies are used is unknown. OBJECTIVE To determine through a systematic review and meta-analysis (1) whether complete revascularization is associated with decreased CV mortality and (2) whether heterogeneity in the association occurs when FFR- and angiography-guided PCI strategies for nonculprit lesions are performed. DATA SOURCES A systematic search of MEDLINE, Embase, ISI Web of Science, and CENTRAL (Cochrane Central Register of Controlled Trials) from database inception to September 30, 2019, was performed. Conference proceedings were also reviewed from January 1, 2002, to September 30, 2019. STUDY SELECTION English-language randomized clinical trials comparing complete revascularization vs culprit-lesion-only PCI in patients with STEMI and multivessel disease were included. DATA EXTRACTION AND SYNTHESIS The combined odds ratio (OR) was calculated with the random-effects model using the Mantel-Haenszel method (sensitivity with fixed-effects model). Heterogeneity was measured using the I-2 statistic. Publication bias was evaluated using the inverted funnel plot approach. Data were analyzed from October 2019 to January 2020. MAIN OUTCOMES AND MEASURES Cardiovascular death and the composite of CV death or new MI. RESULTS Ten randomized clinical trials involving 7030 unique patients were included. The weighted mean follow-up time was 29.5 months. Complete revascularization was associated with reduced CV death compared with culprit-lesion-only PCI (80 of 3191 [2.5%] vs 106 of 3406 [3]%1 OR, 0.69 [95% CI, 0.48-0.99]; P =.05; fixed-effects model OR, 0.74 [95% CI, 0.55-0.99]; P =.04). All-cause mortality occurred in 153 of 3426 patients (4.5%) in the complete revascularization group vs 177 of 3604 (4.9%) in the culprit-lesion-only group (OR, 0.84 [95% [I, 0.67-1.05]; P =.13; I-2 = 0%). Complete revascularization was associated with a reduced composite of CV death or new MI (192 of 2616 [7.3%] vs 266 of 2586 [10.3%]; OR, 0.69 [95% [I, 0.55-0.87]; P =.001; fixed-effects model OR, 0.69 [95% [I, 0.57-0.84]; P <.001), with no heterogeneity in this outcome when complete revascularization was performed using an FFR-guided strategy (OR, 0.78 [95% CI, 0.43-1.44]) or an angiography-guided strategy (OR, 0.61 [95% CI, 0.38-0.97]; P =.52 for interaction). CONCLUSIONS AND RELEVANCE In patients with STEMI and multivessel disease, complete revascularization was associated with a reduction in CV mortality compared with culprit-lesion-only PCI. There was no differential association with treatment between FFR- and angiography-guided strategies on major CV outcomes.

  • Percutaneous Coronary Intervention vs Medical Therapy for Coronary Lesions With Positive Fractional Flow Reserve (FFR) but Preserved Pressure-Bounded Coronary Flow Reserve (CFR): A Substudy of the Randomized Compare-Acute Trial
  • 2021
  • Ingår i: JOURNAL OF INVASIVE CARDIOLOGY. - 1042-3931 .- 1557-2501. ; 33:7
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives. Performing percutaneous coronary intervention (PCI) for fractional flow reserve (FFR) positive coronary lesions improves clinical outcomes and is recommended by international guidelines. It has been hypothesized that lesions with a positive FFR but a preserved coronary flow reserve (CFR) are less likely to be flow limiting and might best be treated medically. We investigated the association of CFR in FFR-positive lesions with clinical outcomes when treated medically, as well as the treatment effect of PCI vs medical therapy in FFR-positive lesions and a preserved CFR. Methods. We performed a substudy of the randomized, multicenter Compare-Acute trial, in which stabilized ST-segment elevation myocardial infarction (STEMI) patients with non-culprit lesions were randomized to either FFR-guided PCI or medical therapy. Based on baseline and hyperemic pressure gradients, we computed physiologic limits of CFR, the so-called pressure-bounded CFR (pb-CFR), and classified lesions as low (<2) or preserved (>= 2). The primary endpoint was 12-month major adverse cardiac and cerebrovascular event (MACCE) rate, defined as a composite of death from any cause, non-fatal myocardial infarction, revascularization, or cerebrovascular events. Results. A total of 980 lesions from 885 patients were included in this substudy. In lesions with FFR <= 0.80, a total of 249 patients had a pb-CFR<2 and 29 patients had a preserved CFR (pb-CFR >= 2). The rate of MACCE at 1 year was not significantly different between patients with FFR <= 0.80 and pb-CFR <2 vs patients with FFR <= 0.80 and pb-CFR >= 2 (25% vs 17%, respectively; P=.39). Because of randomization, baseline characteristics were well balanced between patients with FFR <= 0.80 and pb-CFR >= 2 treated by either by PCI or medical therapy. Importantly, in patients with FFR <= 0.80 and pb-CFR >= 2, MACCE occurred more frequently in patients treated medically vs patients treated by PCI (44% vs 0%, respectively; P=.01). Conclusions. Preserved or low pb-CFR did not alter clinical outcomes in patients with a positive FFR. Patients with FFR-positive coronary lesions but a preserved CFR had more clinical events when treated medically vs those treated with PCI.

  • Utility of the ACC/AHA Lesion Classification to Predict Outcomes After Contemporary DES Treatment: Individual Patient Data Pooled Analysis From 7 Randomized Trials.
  • 2022
  • Ingår i: Journal of the American Heart Association. - 2047-9980.
  • Tidskriftsartikel (refereegranskat)abstract
    • Background Use of the modified American College of Cardiology (ACC)/American Heart Association (AHA) lesion classification as a prognostic tool to predict short- and long-term clinical outcomes after percutaneous coronary intervention in the modern drug-eluting stent era is uncertain. Methods and Results Patient-level data from 7 prospective, randomized trials were pooled. Clinical outcomes of patients undergoing single lesion percutaneous coronary intervention with second-generation drug-eluting stent were analyzed according to modified ACC/AHA lesion class. The primary end point was target lesion failure (TLF: composite of cardiac death, target vessel myocardial infarction, or ischemia-driven target lesion revascularization). Clinical outcomes to 5 years were compared between patients treated for noncomplex (class A/B1) versus complex (class B2/C) lesions. Eight thousand five hundred sixteen patients (age 63.1±10.8 years, 70.5% male) were analyzed. Lesions were classified as A, B1, B2, and C in 7.9%, 28.5%, 33.7%, and 30.0% of cases, respectively. Target lesion failure was higher in patients undergoing percutaneous coronary intervention of complex versus noncomplex lesions at 30 days (2.0% versus 1.1%, P=0.004), at 1 year (4.6% versus 3.0%, P=0.0005), and at 5 years (12.4% versus 9.2%, P=0.0001). By multivariable analysis, treatment of ACC/AHA class B2/C lesions was significantly associated with higher rate of 5-year target lesion failure (adjusted hazard ratio, 1.39 [95% CI, 1.17-1.64], P=0.0001) driven by significantly higher rates of target vessel myocardial infarction and ischemia-driven target lesion revascularization. Conclusions In this pooled large-scale analysis, treating complex compared with noncomplex lesions according to the modified ACC/AHA classification with second-generation drug-eluting stent was associated with worse 5-year clinical outcomes. This historical classification system may be useful in the contemporary era for predicting early and late outcomes following percutaneous coronary intervention.

  • Geographical variations in the effectiveness and safety of abbreviated or standard antiplatelet therapy after PCI in patients at high bleeding risk
  • 2024
  • Ingår i: Canadian Journal of Cardiology. - : Elsevier. - 0828-282X .- 1916-7075.
  • Tidskriftsartikel (refereegranskat)abstract
    • In high-bleeding risk (HBR) patients, non-inferiority of 1-month dual antiplatelet therapy (APT) to treatment continuation for ≥2 additional months for the occurrence of net and major adverse clinical events after drug-eluting stent implantation was showed in the MASTER DAPT trial.1 A significant reduction in bleeding was also noted. However, whether these treatment effects of APT are consistent across geographical regions remains uncertain. In the present analyses, the effects of abbreviated or standard APT on the 1-year occurrence of net and major adverse clinical events and bleeding were consistent across geographical regions (Europe, East Asia, and others) [NCT03023020].

    • Background In patients with ST-segment elevation myocardial infarction (STEMI), the use of percutaneous coronary intervention (PCI) to restore blood flow in an infarct-related coronary artery improves outcomes. The use of PCI in non-infarct-related coronary arteries remains controversial. Methods We randomly assigned 885 patients with STEMI and multivessel disease who had undergone primary PCI of an infarct-related coronary artery in a 1:2 ratio to undergo complete revascularization of non-infarct-related coronary arteries guided by fractional flow reserve (FFR) (295 patients) or to undergo no revascularization of non-infarct-related coronary arteries (590 patients). The FFR procedure was performed in both groups, but in the latter group, both the patients and their cardiologist were unaware of the findings on FFR. The primary end point was a composite of death from any cause, nonfatal myocardial infarction, revascularization, and cerebrovascular events at 12 months. Clinically indicated elective revascularizations performed within 45 days after primary PCI were not counted as events in the group receiving PCI for an infarct-related coronary artery only. Results The primary outcome occurred in 23 patients in the complete-revascularization group and in 121 patients in the infarct-artery-only group that did not receive complete revascularization, a finding that translates to 8 and 21 events per 100 patients, respectively (hazard ratio, 0.35; 95% confidence interval [CI], 0.22 to 0.55; P<0.001). Death occurred in 4 patients in the complete-revascularization group and in 10 patients in the infarct-artery-only group (1.4% vs. 1.7%) (hazard ratio, 0.80; 95% CI, 0.25 to 2.56), myocardial infarction in 7 and 28 patients, respectively (2.4% vs. 4.7%) (hazard ratio, 0.50; 95% CI, 0.22 to 1.13), revascularization in 18 and 103 patients (6.1% vs. 17.5%) (hazard ratio, 0.32; 95% CI, 0.20 to 0.54), and cerebrovascular events in 0 and 4 patients (0 vs. 0.7%). An FFR-related serious adverse event occurred in 2 patients (both in the group receiving infarct-related treatment only). Conclusions In patients with STEMI and multivessel disease who underwent primary PCI of an infarct-related artery, the addition of FFR-guided complete revascularization of non-infarct-related arteries in the acute setting resulted in a risk of a composite cardiovascular outcome that was lower than the risk among those who were treated for the infarct-related artery only. This finding was mainly supported by a reduction in subsequent revascularizations. (Funded by Maasstad Cardiovascular Research and others; Compare-Acute ClinicalTrials.gov number, NCT01399736 .).

  • Evaluation and Management of Nonculprit Lesions in STEMI
  • 2020
  • Ingår i: JACC: Cardiovascular Interventions. - : Elsevier BV. - 1936-8798. ; 13:10, s. 1145-1154

    • Nonculprit lesions are frequently observed in patients with ST-segment elevation myocardial infarction. Results from recent randomized clinical trials suggest that complete revascularization after ST-segment elevation myocardial infarction improves outcomes. In this state-of-the-art paper, the authors review these trials and consider how best to determine which nonculprit lesions require revascularization and when this should be performed.

  • Fractional flow reserve-guided percutaneous coronary intervention vs. medical therapy for patients with stable coronary lesions : meta-analysis of individual patient data
  • 2019
  • Ingår i: European Heart Journal. - : Oxford University Press (OUP). - 1522-9645 .- 0195-668X. ; 40:2, s. 180-186
  • Tidskriftsartikel (refereegranskat)abstract
    • Aims: To assess the effect of fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) with contemporary drug-eluting stents on the composite of cardiac death or myocardial infarction (MI) vs. medical therapy in patients with stable coronary lesions. Methods and results: We performed a systematic review and meta-analysis of individual patient data (IPD) of the three available randomized trials of contemporary FFR-guided PCI vs. medical therapy for patients with stable coronary lesions: FAME 2 (NCT01132495), DANAMI-3-PRIMULTI (NCT01960933), and Compare-Acute (NCT01399736). FAME 2 enrolled patients with stable coronary artery disease (CAD), while the other two focused on non-culprit lesions in stabilized patients after acute coronary syndrome. A total of 2400 subjects were recruited from 54 sites world-wide with 1056 randomly assigned to FFR-guided PCI and 1344 to medical therapy. The pre-specified primary outcome was a composite of cardiac death or MI. We included data from extended follow-ups for FAME 2 (up to 5.5 years follow-up) and DANAMI-3-PRIMULTI (up to 4.7 years follow-up). After a median follow-up of 35 months (interquartile range 12-60 months), a reduction in the composite of cardiac death or MI was observed with FFR-guided PCI as compared with medical therapy (hazard ratio 0.72, 95% confidence interval 0.54-0.96; P = 0.02). The difference between groups was driven by MI. Conclusion: In this IPD meta-analysis of the three available randomized controlled trials to date, FFR-guided PCI resulted in a reduction of the composite of cardiac death or MI compared with medical therapy, which was driven by a decreased risk of MI.
