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.

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.
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.
IntroductionIdiopathic 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.MethodsThOracic 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 disseminationThe 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 numberNCT03944928;Pre-results.
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.
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.
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 before 2 or 4 months—without any response—and sometimes exhibited explosive tumoral progression. This descriptive prospective study aimed to assess the management and clinical outcomes of nonresponders with rapid progression, defined as progression‐free survival ≤2 or 2‐4 months under ICI.
•12% of patients with newly diagnosed cancer were obese and 15% underweight.•35% of obese and 75% of underweight patients had prediagnosis weight loss.•BMI was a confounding variable, not an ...independent prognostic factor associated with survival.•Prediagnosis weight loss is a stronger prognostic factor than BMI.
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.
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.
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).
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.
•After TKI-EGFR, SOC is not well codified.•Chemoimmunotherapy +/- bevacizumab is an option with contradictory results.•The safety of this association is reassuring and manageable.•QOL is a decisive ...factor in choosing between different strategies with equivalent efficacy.•PROs appear to be comparable regardless atezolizumab addition to chemotherapy+/-bevacizumab.
In an open-label multicenter non-randomized non-comparative phase II study in patients with stage IIIB/IV non-squamous non-small cell lung cancer (NSCLC), oncogenic addiction (EGFR mutation or ALK/ROS1 fusion), with disease progression after tyrosine-kinase inhibitor and no prior chemotherapy (NCT04042558), atezolizumab, carboplatin, pemetrexed with or without bevacizumab showed some promising result. Beyond the clinical evaluation, we assessed safety and patient-reported outcomes (PROs) to provide additional information on the relative impact of adding atezolizumab to chemotherapy with and without bevacizumab in this population.
Patients received platinum-pemetrexed-atezolizumab-bevacizumab (PPAB cohort) or, if not eligible, platinum-pemetrexed-atezolizumab (PPA cohort). The incidence, nature, and severity of adverse events (AEs) were assessed. PROs were evaluated using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-Core 30 and EORTC QLQ-Lung Cancer 13).
Overall, 68 (PPAB) and 72 (PPA) patients were evaluable for safety. Grade 3–4 AEs occurred in 83.8% (PPAB) and 63.9% (PPA). Grade 3–4 atezolizumab-related AEs occurred in 29.4% and 19.4%, respectively. Grade 3–4 bevacizumab-related AEs occurred in 36.8% (PPAB). Most frequent grade 3–4 AEs were neutropenia (19.1% in PPAB; 23.6% in PPA) and asthenia (16.2% in PPAB; 9.7% in PPA). In PPAB, we observed a global stability in global health security (GHS) score, fatigue and dyspnea with a constant tendency of improvement, and a significant improvement in cough. In PPA, we observed a significant improvement in GHS score with a significant improvement in fatigue, dyspnea and cough. At week 54, we observed an improvement from baseline in GHS score for 49.2% of patients. In both cohorts, patients reported on average no clinically significant worsening in their overall health or physical functioning scores.
PPAB and PPA combinations seem tolerable and manageable in patients with stage IIIB/IV non-squamous NSCLC with oncogenic addiction (EGFR mutation or ALK/ROS1 fusion) after targeted therapies.
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.
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).
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).
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.
•Stage-III-N2 non-small-cell lung cancer (NSCLC) management remains challenging.•The consistency of Tumor Board meeting (TBM) decisions was assessed.•None of the decisions of 27 TBMs for 6 ...stage-III-N2 NSCLCs cases were unanimous.•Decisions not seem associated with local conditions.
Management of stage-III-N2 non-small-cell lung cancer (NSCLC) based on a multimodal strategy (surgery or radiotherapycombined with systemic drugs) remains controversial. Patients are treated with a curative intent, and available data suggestprolonged survival after complete resection. However, no consensual definition of “tumor resectability” exists. This study aimed to analyze the concordanceamong French tumor board meeting (TBM)-emittedtherapeutic decisions forstage-III-N2 NSCLC.
Six patients with stage-III-N2 NSCLC discussed at Saint-Etienne University Hospital’sthoracic TBMs were selected, anonymouslyreported, and submitted to the participating TBMs. The primary goal of this multicenter, prospective, observational study was to assess the consistency of TBMpanel decisions for each case. The secondary endpointwas identifying the demographic or technical factors that potentiallyaffected decision-making.
Twenty-seven TBMs from university hospitals, a cancer center, general hospitals, and a private hospitalparticipated in this study. None of their decisions for the six cases were unanimous.The decisions were homogenous for three cases (78%, 85%, and 88% TBMs opted for medical treatment, respectively),andmore ambivalent for the other three (medical versus surgical strategies were favored by 44%/56%, 46%/54%, and 58%/42% TBMs, respectively). Interestingly, decisions regarding chemoradiationand perioperative chemotherapyinthe medical and surgical strategies, respectively, were also discordant. Hospital type, specialist participation in TBMs, and activity volumes were not significantly associated with therapeutic decisions.
The results of this study highlight substantial disparities amongFrench TBMs regarding therapeutic management of stage-III-N2 NSCLC. The decisions were not associated with local conditions.
