RESUMO
Background: Oncogenic FGFR-TACC fusions are present in 3-5% of high-grade gliomas (HGGs). Fexagratinib (AZD4547) is an oral FGFR1-3 inhibitor with preclinical activity in FGFR-TACC+ gliomas. We tested its safety and efficacy in patients with recurrent FGFR-TACCâ +â HGGs. Patients and Methods: TARGET (NCT02824133) is a phase I/II open-label multicenter study that included adult patients with FGFR-TACCâ +â HGGs relapsing after ≥1 line of standard chemoradiation. Patients received fexagratinib 80 mg bd on a continuous schedule until disease progression or unacceptable toxicity. The primary endpoint was the 6-month progression-free survival rate (PFS6). Results: Twelve patients with recurrent IDH wildtype FGFR-TACCâ +â HGGs (all FGFR3-TACC3+) were included in the efficacy cohort (male/female ratioâ =â 1.4, median ageâ =â 61.5 years). Most patients (67%) were included at the first relapse. The PFS6 was 25% (95% confidence interval 5-57%), with a median PFS of 1.4 months. All patients without progression at 6 months (nâ =â 3) were treated at first recurrence (versus 56% of those in progression) and remained progression-free for 14-23 months. The best response was RANO partial response in 1 patient (8%), stable disease in 5 (42%), and progressive disease in 6 (50%). Median survival was 17.5 months from inclusion. Grade 3 toxicities included lymphopenia, hyperglycaemia, stomatitis, nail changes, and alanine aminotransferase increase (nâ =â 1 each). No grade 4-5 toxicities were seen. A 32-gene signature was associated with the benefit of FGFR inhibition in FGFR3-TACC3â +â HGGs. Conclusions: Fexagratinib exhibited acceptable toxicity but limited efficacy in recurrent FGFR3-TACC3â +â HGGs. Patients treated at first recurrence appeared more likely to benefit, yet additional evidence is required.
RESUMO
PURPOSE: The effect of chronic use of low-dose aspirin (LDA) on overall cancer is still unclear owing to many controversial results and methodological limitations of studies. This study aimed to assess the effect of LDA use on overall cancer incidence among the French population. METHODS: We conducted a 10-year historical cohort study using the permanent sample of the French national health care databases: the Système National des Données de Santé (SNDS). We used data for 111 025 individuals aged 50 to 80 years at study entry (January 1, 2006) without prevalent cancer or LDA use. Individuals were followed until the earliest of cancer incidence, death from any cause, exit from the database, or end of the study on December 31, 2015. We estimated the effect of LDA on cancer incidence by using a dynamic model to account for the competing risk of death in the presence of time-dependent exposure and risk factors. RESULTS: LDA use was associated with reduced 10-year risk of cancer (subdistribution hazard ratio [SHR] 0.81 [95% CI 0.77-0.86]). The SHRs were 0.88 [0.82-0.94] for men and 0.93 [0.85-1.02] for women. Moreover, each additional year of LDA use was associated with reduced 10-year risk of cancer (SHR 0.93 [0.92-0.95]). LDA use was also associated with reduced 10-year risk of death (SHR 0.86 [0.82-0.91]). CONCLUSIONS: This is the first population-based study to demonstrate a protective effect of LDA on overall cancer incidence and to account for the main methodological issues of previous observational studies.

OBJECTIVE: To compare computed high b-value diffusion-weighted images (c-DWI) derived from low b-value DWI images and acquired high b-value DWI (a-DWI), in overall image quality and prostate cancer detection rate. MATERIALS AND METHODS: A total of 124 consecutive men with suspected prostate cancer (PCa) underwent diagnosis prostate MRI on a 3.0 T MR system using a 32-channel phased-array torso coil. Among them, 63 underwent prostate biopsy. MRI protocol included 3DT2w images, high resolution Fov Optimized and Constrained Undistorted Single-Shot (FOCUS™) DWI images with b-values of 100, 400, 800, and 2000 s/mm2 and dynamic contrast enhanced images. C-DWI images (2000 and 2500 s/mm2) were derived from the three lower acquired b-value DWI images using a mono-exponential diffusion decay. C-DWI and acquired high b-value DWI (a-DWI) (2000 s/mm2) were compared for image quality (background signal suppression, anatomic clarity, ghosting, distortion) and tumor conspicuity by four radiologists. RESULTS: C-DWIs demonstrated higher rating than a-DWIs for overall image quality despite worsened ghosting. In patients with a biopsy, similar detection rate was observed while conspicuity was better with c-DWI (p < 0.001). Non-acquisition of high b-value a-DWI reduced total acquisition time by 220 s per patient. CONCLUSION: C-DWI provides a substantial reduction in acquisition time while maintaining comparable prostate cancer detection rate and improving global image quality. KEY POINTS: ⢠Computed DWI improves global quality of prostate MRI. ⢠Computed DWI improves analysis of DWI images with decrease acquisition time. ⢠Computed DWI provides greater background suppression of parenchyma and improves conspicuity of suspicious lesion.

BACKGROUND: Determinants of the progression of aortic stenosis (AS) remained unclear. Metabolic syndrome (MetS) and diabetes are suspected to play an active role but literature is scarce and results conflicting. We sought to assess their impact in an ongoing prospective cohort of asymptomatic patients with at least mild AS. METHODS: We enrolled 203 patients (73±9years, 75% men) with at least 2years of follow-up. Risk-factors assessment was performed at baseline. Annual progression was calculated as [(final-baseline measurements)/follow-up duration] for both mean pressure gradient (MPG) and degree of aortic valve calcification (AVC) measurements. RESULTS: Ninety-nine patients (49%) had MetS and 50 (25%) had diabetes (including 39 with MetS). After a mean follow-up of 3.2±1.2years, AS progression was not different between patients with and without MetS either using MPG (+3±3 vs. +4±4mmHg/year, p=0.25) or AVC (+211±231 vs. +225±222AU/year, p=0.75). Same results were obtained for patients with diabetes (3±3 vs. 4±4mmHg/year p=0.53, 187±140 vs. 229±248AU/year p=0.99). MetS had no impact on AS progression in all tested subgroups based on age, statin prescription, valve anatomy and AS severity (all p≥0.10). CONCLUSION: In our prospective cohort of AS patients, we found no impact of MetS or diabetes on AS progression. Although MetS and diabetes should be actively treated, no impact on AS progression should be expected. Our results support the theory that if cardiovascular risk-factors may play a role at the early phase of AS disease they have no or limited influence on AS progression.

PURPOSE: Administrative databases are increasingly being used in cancer observational studies. Identifying incident cancer in these databases is crucial. This study aimed to develop algorithms to estimate cancer incidence by using health administrative databases and to examine the accuracy of the algorithms in terms of national cancer incidence rates estimated from registries. METHODS: We identified a cohort of 463 033 participants on 1 January 2012 in the Echantillon Généraliste des Bénéficiaires (EGB; a representative sample of the French healthcare insurance system). The EGB contains data on long-term chronic disease (LTD) status, reimbursed outpatient treatments and procedures, and hospitalizations (including discharge diagnoses, and costly medical procedures and drugs). After excluding cases of prevalent cancer, we applied 15 algorithms to estimate the cancer incidence rates separately for men and women in 2012 and compared them to the national cancer incidence rates estimated from French registries by indirect age and sex standardization. RESULTS: The most accurate algorithm for men combined information from LTD status, outpatient anticancer drugs, radiotherapy sessions and primary or related discharge diagnosis of cancer, although it underestimated the cancer incidence (standardized incidence ratio (SIR) 0.85 [0.80-0.90]). For women, the best algorithm used the same definition of the algorithm for men but restricted hospital discharge to only primary or related diagnosis with an additional inpatient procedure or drug reimbursement related to cancer and gave comparable estimates to those from registries (SIR 1.00 [0.94-1.06]). CONCLUSION: The algorithms proposed could be used for cancer incidence monitoring and for future etiological cancer studies involving French healthcare databases.

The role of autoimmunity targeting epithelial antigens in asthma has been suggested, in particular in non-atopic and severe asthma. Periplakin, a desmosomal component, is involved in epithelial cohesion and intracellular signaling. We detected anti-periplakin IgG antibodies in 47/260 (18 %) patients with asthma, with no association with severity or atopy. In addition, anti-periplakin IgE antibodies were detected in 12 of 138 tested patients (8.7 %) and were more frequently observed in patients with than without nasal polyposis. This study identifies a new autoimmune epithelial target in asthma. Whether periplakin autoimmunity (both IgG and IgE auto-antibodies) is involved in asthma pathogenesis remains to be studied during the disease course of these patients.

OBJECTIVE: To assess the impact of a computer-assisted Screening, Brief Intervention, and Referral to Treatment (SBIRT) on daily consumption of alcohol by patients with hazardous drinking disorder detected after systematic screening during their admission to an emergency department (ED). DESIGN: Two-arm, parallel group, multicentre, randomized controlled trial with a centralised computer-generated randomization procedure. SETTING: Four EDs in university hospitals located in the Paris area in France. PARTICIPANTS: Patients admitted in the ED for any reason, with hazardous drinking disorder detected after systematic screening (i.e., Alcohol Use Disorder Identification Test score ≥5 for women and 8 for men OR self-reported alcohol consumption by week ≥7 drinks for women and 14 for men). INTERVENTIONS: The experimental intervention was computer-assisted SBIRT and the comparator was a placebo-controlled intervention (i.e., a computer-assisted education program on nutrition). Interventions were administered in the ED and followed by phone reinforcements at 1 and 3 months. MAIN OUTCOME MEASURE: The primary outcome was the mean number of alcohol drinks per day in the previous week, at 12 months. Results From May 2005 to February 2011, 286 patients were randomized to the computer-assisted SBIRT and 286 to the comparator intervention. The two groups did not differ in the primary outcome, with an adjusted mean difference of 0.12 (95% confidence interval, -0.88 to 1.11). CONCLUSIONS: There was no additional benefit of the computer-assisted alcohol SBIRT as compared with the computer-assisted education program on nutrition among patients with hazardous drinking disorder detected by systematic screening during their admission to an ED.

OBJECTIVE: Myocardial fibrosis has been proposed as an outcome predictor in asymptomatic patients with severe aortic stenosis (AS) that may lead to consider prophylactic surgery. It can be detected using MRI but its widespread use is limited and development of substitute biomarkers is highly desirable. We analysed the determinants and prognostic value of galectin-3, one promising biomarker linked to myocardial fibrosis. METHODS: Patients with at least mild degenerative AS enrolled between 2006 and 2013 in two ongoing studies, COFRASA/GENERAC (COhorte Française de Rétrécissement Aortique du Sujet Agé/GENEtique du Rétrécissement Aortique), aiming at assessing the determinants of AS occurrence and progression, constituted our population. RESULTS: We prospectively enrolled 583 patients. The mean galectin-3 value was 14.3±5.6â ng/mL. There was no association between galectin-3 and functional status (p=0.55) or AS severity (p=0.58). Independent determinants of galectin-3 were age (p=0.0008), female gender (p=0.04), hypertension (p=0.002), diabetes (p=0.02), reduced left ventricular ejection fraction (p=0.01), diastolic dysfunction (E/e', p=0.02) and creatinine clearance (p<0.0001). Among 330 asymptomatic patients at baseline, galectin-3 was neither predictive of outcome in univariate analysis (p=0.73), nor after adjustment for age, gender, rhythm, creatinine clearance and AS severity (p=0.66). CONCLUSIONS: In a prospective cohort of patients with a wide range of AS severity, galectin-3 was not associated with AS severity or functional status. Main determinants of galectin-3 were age, hypertension and renal function. Galectin-3 did not provide prognostic information on the occurrence of AS-related events. Our results do not support the use of galectin-3 in the decision-making process of asymptomatic patients with AS. TRIAL REGISTRATION NUMBER: COFRASA NCT00338676 and GENERAC CT00647088.

Bronchiectasis, bronchiolectasis, and bronchiolisation of alveolar regions are salient features of idiopathic pulmonary fibrosis (IPF). We asked whether IPF was associated with physiological changes consistent with increases in the volume of conducting airways, and whether airway volume was related to the severity of lung fibrosis. Patients with IPF (N = 57, vital capacity-VC: 73 ± 20%), patients with non-IPF interstitial lung disease (non-IPF ILD, N = 24, VC = 78 ± 18%) and controls without lung disease (N = 51, VC = 112 ± 21%) underwent volumetric capnography for the determination of conducting airway volume using Fletcher's equal area method, reported to predicted total lung capacity to control for the effect of lung size (VDaw/TLCp, mL/L). VDaw/TLCp was higher in patients with IPF (45.3 ± 12.8 ml L(-1)) in comparison with controls (34.2 ± 11.0 ml L(-1), p < 0.0001) and patients with non-IPF ILD (39.5 ± 9.2 ml L(-1), p = 0.0496). The same differences were observed when analysis was restricted to subjects with moderate IPF (VC ⩾ 80% predicted). Among IPF patients, VDaw/TLCp was correlated with neither the mMRC dyspnea scale, nor VC, nor carbon monoxide transfer factor, nor computed tomography fibrosis scores. Volumetric capnography showed higher conducting airway volume in IPF patients in comparison with controls and non-IPF ILDs, independent of disease severity. This result is consistent with either anatomical predisposition or dilation/longitudinal growth of conducting airways in IPF.

BACKGROUND: Aortic valve stenosis (AS) is a progressive disease, but the impact of baseline AS haemodynamic or anatomic severity on AS progression remains unclear. METHODS: In 149 patients (104 mild AS, 36 moderate AS and 9 severe AS) enrolled in 2 ongoing prospective cohorts (COFRASA/GENERAC), we evaluated AS haemodynamic severity at baseline and yearly, thereafter, using echocardiography (mean pressure gradient (MPG)) and AS anatomic severity using CT (degree of aortic valve calcification (AVC)). RESULTS: After a mean follow-up of 2.9±1.0 years, mean MGP increased from 22±11 to 30±16 mm Hg (+3±3 mm Hg/year), and mean AVC from 1108±891 to 1640±1251 AU (arbitrary units) (+188±176 AU/year). Progression of AS was strongly related to baseline haemodynamic severity (+2±3 mm Hg/year in mild AS, +4±3 mm Hg/year in moderate AS and +5±5 mm Hg/year in severe AS (p=0.01)), and baseline haemodynamic severity was an independent predictor of haemodynamic progression (p=0.0003). Annualised haemodynamic and anatomic progression rates were significantly correlated (r=0.55, p<0.0001), but AVC progression rate was also significantly associated with baseline haemodynamic severity (+141±133 AU/year in mild AS, +279±189 AU/year in moderate AS and +361±293â AU/year in severe AS, p<0.0001), and both baseline MPG and baseline AVC were independent determinants of AVC progression (p<0.0001). CONCLUSIONS: AS progressed faster with increasing haemodynamic or anatomic severity. Our results suggest that a medical strategy aimed at preventing AVC progression may be useful in all subsets of patients with AS including those with severe AS and support the recommended closer follow-up of patients with AS as AS severity increases.

PURPOSE: To describe the initial and follow-up CT features of interstitial lung disease associated with anti-synthetase syndrome (AS-ILD). MATERIALS AND METHODS: Two independent thoracic radiologists retrospectively analysed thin-section CT images obtained at diagnosis of AS-ILD in 33 patients (17 positive for anti-Jo1, 13 for anti-PL12, and three for anti-PL7 antibodies). They evaluated the pattern, distribution and extent of the CT abnormalities. They also evaluated the change in findings during follow-up (median 27 months; range 13-167 months) in 26 patients. RESULTS: At diagnosis, ground-glass opacities (100%), reticulations (87%) and traction bronchiectasis (76%) were the most common CT findings. Consolidations were present in 45% of patients. A non-specific interstitial pneumonia (NSIP), organizing pneumonia (OP) or mixed NSIP-OP CT pattern were observed in 15 out of 33 (45%), seven out of 33 (21%) and eight out of 33 (24%) patients, respectively, whereas the CT pattern was indeterminate in three patients. During follow-up, consolidations decreased or disappeared in 11 out of 12 patients (92%), among which seven within the first 6 months, but honeycombing progressed or appeared in ten out of 26 patients (38%) and overall disease extent increased in nine out of 26 patients (35%). CONCLUSION: CT features at diagnosis of AS-ILD mainly suggest NSIP and OP, isolated or in combination. Consolidations decrease or disappear in most cases but the disease may progress to fibrosis in more than one third of patients.
