RESUMEN

Purpose: Severe asthma affects 5 to 10% of asthmatics and accounts for a large part of asthma-related morbidity and costs. The determinants of asthma severity are poorly understood. We tested the hypothesis that asthma severity was associated with 1) atopy and allergy and 2) markers associated with environmental exposure. Patients and Methods: Data from the FASE-CPHG study, a cross-sectional, observational, multicenter investigation, were analyzed to identify markers associated with asthma severity. Asthma severity was gauged using the ASSESS score, encompassing symptom control, exacerbations, FEV1 and therapeutic load. Bivariate and multivariate analyses were used to identify patient characteristics associated with the ASSESS score. Results: The analysis involved 948 patients, with 592 women, of which 447 patients (47%) had severe asthma. Among these, 491 patients (52%) had at least one positive aeroallergen skin prick test and 525 (55%) had at least one allergic disease among atopic dermatitis, chronic rhinitis and food allergy. The mean±SD ASSESS score was 11.2±3.4. Characteristics associated with a higher ASSESS score were female sex, secondary or lower education, unemployed occupational status, smoking, work-aggravated asthma and urban housing. There was no association between the ASSESS score and allergic diseases, aeroallergen-specific skin prick tests and IgEs, or blood eosinophil counts. Conclusion: While atopy and allergy were frequent among asthmatics, neither was associated with asthma severity. Modifiable environmental factors such as smoking, urban housing and work-aggravated asthma were independently associated with asthma severity.

RESUMEN

BACKGROUND: Although ALK-translocated (ALK+) advanced non-small cell lung cancers (aNSCLCs) are currently treated with second- or third-generation ALK inhibitors (ALK-TKIs), some patients respond durably to the first-generation ALK-TKI crizotinib. OBJECTIVE: This study aimed to describe the clinical characteristics of these long-term responders. PATIENTS AND METHODS: This national, multicenter, retrospective, non-interventional study included patients with ALK+ aNSCLCs and long-term responses to first (L1)- or subsequent (≥ L2)-line crizotinib, defined, respectively, as treatments lasting > 18 and > 10 months. Median treatment duration (mDOT) was the primary endpoint. RESULTS: A total of 85 patients (32 L1 and 53 ≥ L2 responders) from 23 centers were included (receiving crizotinib between 10/24/2011-10/02/2018): median age of 59 years, 83.6% non-smokers or ex-smokers, 85.9% performance status (PS) 0/1, 94.1% with adenocarcinomas, median of one metastatic site, and 22.4% with brain metastases (BMs). After median follow-up of 73.4 [95% confidence interval, 67.5-79.9] months, respective L1 and ≥ L2 mDOTs were 43.3 [26.7-56.8] and 29.6 [22.6-35.8] months, with overall survival (OS) not reached (NR) and 116.2 [83.4-NR] months. BM presence or absence did not affect mDOT (31.4 versus 32.9 months) but significantly impacted median OS (70.6 versus 158.6 months; p = 0.0008). Progression on crizotinib was paucisymptomatic (74.1%) and oligometastatic (34.8%), especially BMs (42.4%). After crizotinib discontinuation, 65 (76.5%) patients received subsequent systemic therapy: 57 (67.1%) with second-generation ALK-TKIs. Respective mDOTs of first- and second-line post-crizotinib ALK-TKIs lasted 19.4 [14.9-25.6] and 11.1 [4.8-17.9] months, respectively. CONCLUSIONS: Most ALK+ aNSCLC patients with prolonged crizotinib efficacy had paucisymptomatic and oligometastatic disease without BMs. They subsequently benefited from a sequential strategy with other ALK-TKIs.

RESUMEN

Background: Long-term changes in lung cancer (LC) patients are difficult to evaluate. We report results from the French KBP-2020 real-life cohort. Methods: KBP-2020 was a prospective cohort that included all patients diagnosed with LC in 2020, in nonacademic public hospital in France. Patient and tumour characteristics were described and compared with similarly designed cohorts in 2000 and 2010. Findings: In 2020, 82 centers included 8,999 patients diagnosed with LC. The proportion of women increased: 34·6% (3114/8999) compared to, 24·3% (1711/7051) and 16·0% (904/5667) in 2010 and 2000 (p<0·0001). The proportion of non-smokers was higher in 2020 (12·6%, 1129/8983) than in previous cohorts (10·9% (762/7008) in 2010; 7·2% (402/5586) in 2000, p<0·0001). In 2020, at diagnosis, 57·6% (4405/7648) of patients had a metastatic/disseminated stage non-small-cell lung cancer (NSCLC) (58·3% (3522/6046) in 2010; 42·6% (1879/4411) in 2000, p<0·0001). Compared with 2000 and 2010 data, early survival improved slightly. In 2020, 3-month mortality of NSCLC varied from 3·0% [2·2 - 3·8] for localized to 9·6% [8·1 - 11·0] for locally advanced to 29·2% [27·8 - 30·6] for metastatic and was 24·8% [22·3 - 27·3] for SCLC. Interpretation: To our knowledge KBP cohorts have been the largest, prospective, real-world cohort studies involving LC patients conducted in worldwide. The trend found in our study shows an increase in LC in women and still a large proportion of patients diagnosed at metastatic or disseminated stage. Funding: The study was promoted by the French College of General Hospital Pulmonologists with financial support of industrials laboratories.

RESUMEN

BACKGROUND: Even though COVID-19 clinical features, pathogenesis, complications, and therapeutic options have been largely described in the literature, long-term consequences in patients remain poorly known. METHODS: The French, multicentre, non-interventional SISCOVID study evaluated lung impairment three (M3) and six months (M6) after hospital discharge in patients recovered from COVID-19. Evaluation was based on clinical examination, pulmonary function tests, and chest computed tomography (CT-scan). RESULTS: Of the 320 included patients (mean age: 61 years; men: 64.1%), 205 had had a severe form of COVID-19, being hospitalised in an intensive care unit (ICU), and requiring high flow nasal cannula, non-invasive ventilation, or invasive mechanical ventilation. At M6, 54.1% of included patients had persistent dyspnoea (mMRC score ≥1), 20.1% severe impairment in gas diffusing capacity (DLCO <60% pred.), 21.6% restrictive ventilatory pattern (total lung capacity <80% pred.), and 40% a fibrotic-like pattern at CT-scan. Fibrotic-like pattern and restrictive ventilatory pattern were significantly more frequent in patients recovered from severe than non-severe COVID-19. Improved functional and radiological outcomes were observed between M3 and M6. At M6, age was an independent risk factor for severe DLco impairment and fibrotic-like pattern and severe COVID-19 form was independent risk factor for restrictive ventilatory profile and fibrotic-like pattern. CONCLUSION: Six months after discharge, patients hospitalised for COVID-19, especially those recovered from a severe form of COVID-19, frequently presented persistent dyspnoea, lung function impairment, and persistent fibrotic-like pattern, confirming the need for long-term post-discharge follow-up in these patients and for further studies to better understand long-term COVID-19 lung impairment.

RESUMEN

PURPOSE: Targeted therapies (TT) and immune checkpoint blockers (ICB) have revolutionized the approach to non-small cell lung cancer (NSCLC) treatment in the era of precision medicine. Their impact as switch maintenance therapy based on molecular characterization is unknown. PATIENTS AND METHODS: SAFIR02-Lung/IFCT 1301 was an open-label, randomized, phase II trial, involving 33 centers in France. We investigated eight TT (substudy-1) and one ICB (substudy-2), compared with standard-of-care as a maintenance strategy in patients with advanced EGFR, ALK wild-type (wt) NSCLC without progression after first-line chemotherapy, based on high-throughput genome analysis. The primary outcome was progression-free survival (PFS). RESULTS: Among the 175 patients randomized in substudy-1, 116 received TT (selumetinib, vistusertib, capivasertib, AZD4547, AZD8931, vandetanib, olaparib, savolitinib) and 59 standard-of-care. Median PFS was 2.7 months [95% confidence interval (CI), 1.6-2.9] with TT versus 2.7 months (1.6-4.1) with standard-of-care (HR, 0.97; 95% CI, 0.7-1.36; P = 0.87). There were no significant differences in PFS within any molecular subgroup. In substudy-2, 183 patients were randomized, 121 received durvalumab and 62 standard-of-care. Median PFS was 3.0 months (2.3-4.4) with durvalumab versus 3.0 months (2.0-5.1) with standard-of-care (HR, 0.86; 95% CI, 0.62-1.20; P = 0.38). Preplanned subgroup analysis showed an enhanced benefit with durvalumab in patients with PD-L1 tumor proportion score (TPS) ≥1%, (n = 29; HR, 0.29; 95% CI, 0.11-0.75) as compared with PD-L1 <1% (n = 31; HR, 0.71; 95% CI, 0.31-1.60; Pinteraction = 0.036). CONCLUSIONS: Molecular profiling can feasibly be implemented to guide treatment choice for the maintenance strategy in EGFR/ALK wt NSCLC; in this study it did not lead to substantial treatment benefits beyond durvalumab for PD-L1 ≥ 1 patients.

RESUMEN

PURPOSE: Double inhibition of epidermal growth factor receptor (EGFR) using a tyrosine kinase inhibitor plus a monoclonal antibody may be a novel treatment strategy for non-small cell lung cancer (NSCLC). We assessed the efficacy and toxicity of afatinib + cetuximab versus afatinib alone in the first-line treatment of advanced EGFR-mutant NSCLC. PATIENTS AND METHODS: In this phase II, randomized, open-label study, patients with stage III/IV EGFR-positive NSCLC were randomly assigned (1:1) to receive afatinib (group A) or afatinib + cetuximab (group A + C). Oral afatinib 40 mg was given once daily; cetuximab 250 mg/m² was administered intravenously on day 15 of cycle 1, then every 2 weeks at 500 mg/m² for 6 months. The primary endpoint was time to treatment failure (TTF) rate at 9 months. Exploratory analysis of EGFR circulating tumor DNA in plasma was performed. RESULTS: Between June 2016 and November 2018, 59 patients were included in group A and 58 in group A + C. The study was ended early after a futility analysis was performed. The percentage of patients without treatment failure at 9 months was similar for both groups (59.3% for group A vs. 64.9% for group A + C), and median TTF was 11.1 (95% CI, 8.5-14.1) and 12.9 (9.2-14.5) months, respectively. Other endpoints, including progression-free survival and overall survival, also showed no improvement with the combination versus afatinib alone. There was a slight numerical increase in grade ≥3 adverse events in group A + C. Allele frequency of the EGFR gene mutation in circulating tumor DNA at baseline was associated with shorter PFS, regardless of the treatment received. CONCLUSIONS: These results suggest that addition of cetuximab to afatinib does not warrant further investigation in treatment-naïve advanced EGFR-mutant NSCLC.

RESUMEN

INTRODUCTION: Idiopathic pulmonary fibrosis (IPF) is the most common and severe interstitial lung disease (ILD). It is a progressive disease that requires a regular follow-up: clinical examination, pulmonary function testing (PFT) and CT scan, which is performed yearly in France. These exams have two major disadvantages: patients with severe dyspnoea have difficulties to perform PFT and repeated CT scans expose to high dose of radiations. Considering these limits, it would be relevant to develop new tools to monitor the progression of IPF lesions. Three main signs have been described in ILD with lung ultrasound (LUS): the number of B lines, the irregularity and the thickening of the pleural line. Cross-sectional studies already correlated the intensity of these signs with the severity of fibrosis lesions on CT scan in patients with IPF, but no prospective study described the evolution of the three main LUS signs, nor the correlation between clinical evaluation, PFT and CT scan. Our hypothesis is that LUS is a relevant tool to highlight the evolution of pulmonary lesions in IPF. The main objective of our study is to show an increase in one or more of the three main LUS signs (total number of B lines, pleural line irregularity score and pleural line thickness) during the follow-up. METHODS: ThOracic Ultrasound in Idiopathic Pulmonary Fibrosis Evolution is a French prospective, multicentric and non-interventional study. Every 3 months, patients with IPF will have a clinical examination, PFT and LUS. CT data will be collected if the CT scan is performed within 3 months before the inclusion; the second CT scan will be performed from 9 to 12 months after the inclusion. The presence, location and severity of LUS signs will be recorded for each patient, and their correlation with clinical, functional and CT scan evolution will be evaluated. 30 patients will be enrolled. ETHICS AND DISSEMINATION: The protocol was approved by the French Research Ethics Committee (Comité de Protection des Personnes SUD OUEST ET OUTRE MER II, reference RIPH3-RNI19-TOUPIE) on 11 April 2019. Results will be disseminated via peer-reviewed publication and presentation at international conferences. TRIAL REGISTRATION NUMBER: NCT03944928;Pre-results.

RESUMEN

The usefulness and feasibility of a global allergens avoidance method with counselors visiting patients' home for allergens measures and adapted advices were prospectively evaluated through asthma control and environment evaluation. Twenty seven patients were prospectively included and compared to a cohort of 30 control patients. The level of control of asthma at inclusion and after 1 year was evaluated by the clinical signs, the evolution of the FEV1, and the healthcare use. Environmental measurements included the fungal load of 5 surfaces of the dwellings and the evaluation of moisture. A significant clinical improvement in the population that benefited from the home counselors visit was observed compared to the baseline (p < 0.0001), as well as a decreased number of hospitalizations for asthma and of the consumption of anti-asthma drugs (p < 0.01). Dampness markers slightly improved with an improvement of the fungal loads in two-third of the dwellings.

RESUMEN

BACKGROUND: Immune checkpoint inhibitors (ICIs) have been approved as second-line therapy for advanced non-small cell lung cancers (NSCLCs) progressing after platinum-based chemotherapy. However, some patients' disease progressed rapidly and sometimes exhibited explosive tumor progression. This descriptive, prospective study aimed to assess the characteristics of nonresponders with rapid progression (RP), defined as progression-free survival (PFS) ≤2 or 2-4 months under ICIs. METHODS: This analysis included all consecutive ICI-treated (second-or-more line) patients with RP ≤4 months from 1 September 2016 to 31 August 2017 and compared the clinical characteristics, treatments, and outcomes (overall survival [OS]; responses; PFS, according to treatment line) of NSCLCs that progressed after ≤2 vs 2-4 months on ICIs. RESULTS: Comparisons of the 224 (70.2%) patients with ≤2-month and 95 (29.8%) with 2- to 4-month RP revealed the former had less frequent nonsmokers and ECOG PS = 0, more frequent stage IV disease and higher neutrophil/lymphocyte ratio. Their respective ICI PFS rates were: 1.6 [95% CI: 0.1-2] and 2.7 [2.0-4.2] months, with 16.5% and 11.6% having partial responses to first- and second-line therapies post-ICI chemotherapy. Their respective median OS rates were 6.0 and 9.0 months (P ≤ .009). Multivariate analysis retained only PFS of the first-line therapy pre-ICI and neutrophil/lymphocyte ratio at ICI onset as being significantly associated with ≤2-month RP. CONCLUSION: In the real-life setting, NSCLC RP on ICI remains a challenge. New descriptive and analytic studies are needed to identify factors predictive of RP.

RESUMEN

Objectives: To assess how physicians and surgeons carried out malnutrition screening and follow-up for patients with lung cancer. Materials and methods: We carried out an expert opinion survey in France using an anonymous self-administered online questionnaire. Results: In 2017, 206 practitioners responded, of which 60.7% were pulmonologists, 17.4% thoracic surgeons, 11.2% oncologists, and 10.7% radiotherapists. At initial diagnosis, 79.3% of practitioners recorded patients' percentage of weight loss. During follow-up examinations, 67.5% recorded this data for patients at risk of malnutrition and 70.4 % for malnourished patients. Food intake was evaluated by 21.7% of practitioners at initial diagnosis. Surgeons assessed percentage of weight loss and food intake significantly less often than pulmonologists did, they were less likely to request serum albumin tests and waited for a greater percentage of weight loss before referring patients to a nutrition professional. All practitioners were well aware of the prevalence of malnutrition among lung cancer patients and its consequences. The main factors preventing optimal nutritional assessment reported by practitioners were a lack of time and limited specialized knowledge. Conclusion: Nutritional assessment remained suboptimal, especially for surgical patients. The importance granted to malnutrition needs to be increased for patients with lung cancer, especially in surgical departments. Highlights Physicians and thoracic surgeons are well aware of the prevalence and consequences in lung cancer patients. Thoracic surgeons seemed to be less sensitized to malnutrition screening than pulmonologists. Lack of time and limited specialized knowledge were reported as the main factors preventing optimal nutritional assessment.

RESUMEN

BACKGROUND: An international consensus proposed in 2011 a definition and classification system for cachexia (CAX), mainly based on weight loss, sarcopenia [skeletal muscle mass (SMM) loss], inflammation, and anorexia. The aim of this study was to stage CAX in non-small-cell lung cancer (NSCLC) patients by using a classification based on the Fearon criteria and supported by quantifiable parameters. METHODS: This was a cross-sectional and non-interventional multicentre study. SMM was assessed by analysing L3 computed tomography-scan images. Patients completed the anorexia/CAX subscale of the Functional Assessment of Anorexia/Cachexia Therapy, EORTC QLQ-C30 quality of life (QoL) and International Physical Activity Questionnaire (IPAQ). RESULTS: Patients were recruited in 56 sites. The analysis population comprised 531 patients, and SMM was assessed in 312 patients. Male patients were 66.5%, with a mean (SD) age of 65.2 (10.0) years, 79.9% were PS 0-1, and the tumour stage was mainly IIIB-IV (87.3%). Overall, 38.7% of patients had CAX, 33.8% pre-CAX, and 0.9% refractory CAX. Molecular tumour profiles were significantly associated with the presence of CAX: 23.9% in EGFR, ALK, ROS1, BRAF, or HER2+ patients, 41.4% in K-RAS+, and 43.2% in patients with no molecular abnormality (P = 0.003). The more advanced the CAX stage, the poorer the scores of functional items of the QoL (P < 0.001) and International Physical Activity Questionnaire (P < 0.001). Sarcopenia was present in 66.7% of CAX and 68.5% of pre-CAX patients. Overall, 43.8% of pre-CAX patients had only sarcopenia with limited weight loss (≤2%) and no anorexia. CONCLUSIONS: This is the first study to show the distribution of CAX in a population of NSCLC patients and an association between molecular abnormality in NSCLC and CAX. The original Fearon classification for CAX stages was supported by the associated functional QoL scores and physical activity levels, resulting in a clinically relevant system for detection of early stages of CAX.

RESUMEN

The increasingly female face of chronic obstructive pulmonary disease (COPD) prevalence among women has equalled that of men since 2008, due in part to increased tobacco use among women worldwide and exposure to biomass fuels. This finding is supported by a number of characteristics. There is evidence of susceptibility to smoking and other airborne contaminants, along with epidemiological and phenotypic manifestations. COPD has thus become the leading cause of death in women in the USA. The clinical presentation is characterised by increasingly pronounced dyspnoea with a marked tendency towards anxiety and depression, undernutrition, nonsmall cell lung cancer (especially adenocarcinoma) and osteoporosis. Quality of life is also more significantly impacted. The theories advanced to explain these differences involve the role played by oestrogens, impaired gas exchange in the lungs and smoking habits. While these differences require appropriate therapeutic responses (smoking cessation, pulmonary rehabilitation, long-term oxygen therapy), barriers to the treatment of women with COPD include greater under-diagnosis than in men, fewer spirometry tests and medical consultations. Faced with this serious public health problem, we need to update and adapt our knowledge to the epidemiological changes.

RESUMEN

OBJECTIVES: Recent studies have demonstrated that elevated BMI is associated with improved survival in patients with lung cancer. According to the authors, this "obesity paradox" could be a true benefit or a spurious relationship. In this context, data from the French KBP-2010-CPHG cohort (7,051 patients followed up for primary lung cancer diagnosed in 2010 in the respiratory medicine departments of 104 nonacademic hospitals) were analyzed. METHODS: Patients were stratified according to BMI at diagnosis using the definition of the French-Speaking Society of Clinical Nutrition and Metabolism (Société Francophone de Nutrition Clinique et Métabolisme). Survival was analyzed using log-rank and a univariate Cox model. Prognostic factors were identified using a multivariate Cox model with backward elimination procedure, and with or without inclusion of prediagnosis weight loss in the model. RESULTS: Patients were followed for a median 20.2 months. At diagnosis, respectively 12%, 28%, 45%, and 15% of the 6,595 patients with BMI data were obese, overweight, normal-weight, and underweight; 35%, 43%, 57%, and 75% reported prediagnosis weight loss (i.e., weight loss within the 3 months prior to diagnosis). One-year survival (% [95% CI]) was 53% [50%-57%], 50%, [48%-52%], 43%, [42%-45%], and 32% [29%-35%] in obese, overweight, normal-weight, and underweight patients, respectively (p < 0.001). It was particularly low in underweight patients with prediagnosis weight loss: 27% [24-30%]. BMI did not remain an independent prognostic factor associated with survival when prediagnosis weight loss was introduced in the Cox model. Risk of death was increased by 17%, 23%, and 46% in patients with <5 kg, 5-10 kg, or ≥10 kg prediagnosis weight loss, respectively (p < 0.001). CONCLUSION: BMI is an easy but crude assessment tool. Other variables should be used to improve management of patients, and understanding of how prediagnosis body size and nutritional status are associated with cancer survival.

RESUMEN

By 2020, chronic obstructive pulmonary disease (COPD) will be the third cause of mortality. Extrapulmonary comorbidities influence the prognosis of patients with COPD. Tobacco smoking is a common risk factor for many comorbidities, including coronary heart disease, heart failure and lung cancer. Comorbidities such as pulmonary artery disease and malnutrition are directly caused by COPD, whereas others, such as systemic venous thromboembolism, anxiety, depression, osteoporosis, obesity, metabolic syndrome, diabetes, sleep disturbance and anaemia, have no evident physiopathological relationship with COPD. The common ground between most of these extrapulmonary manifestations is chronic systemic inflammation. All of these diseases potentiate the morbidity of COPD, leading to increased hospitalisations and healthcare costs. They can frequently cause death, independently of respiratory failure. Comorbidities make the management of COPD difficult and need to be evaluated and treated adequately.

RESUMEN

The regulation of the volume and composition of airway surface liquid is achieved through epithelial ion transport processes. In humans, these processes have been characterized in proximal but not distal airways. Segments of human bronchioles were dissected from surgically removed lung pieces. The transmural potential difference of microperfused bronchioles was inhibited by luminal exposure to amiloride and increased when exposed to the Cl secretagogues forskolin and ATP in the presence of amiloride. Human bronchiolar epithelial cells were cultured on permeable supports and studied in Ussing chambers. They generated a short circuit current (Isc) that decreased in response to amiloride and increased in response to forskolin and to ATP in the presence of amiloride. In low-Cl Kreb's Ringer bicarbonate, the baseline Isc and amiloride-induced decrease in Isc were not different, whereas the forskolin- and ATP-induced increases in Isc were smaller. Fluid transport measurement in excised bronchioles revealed a basal absorptive flow that was reduced by amiloride, whereas forskolin and ATP combined induced a secretory flow in the presence of amiloride. We conclude that human bronchioles actively absorb Na and fluid in unstimulated conditions and are capable of active Cl and fluid secretion when exposed to forskolin and to ATP.
