European Lung Cancer Working Party Clinical Practice Guidelines Non-small Cell Lung Cancer: II. Unresectable Non-metastatic Stages

The present guidelines on the management of unresectable non-metastatic non-small cell lung cancer (NSCLC) were formulated by the ELCWP in October 2005. They are designed to answer the following eight questions: 1) Is chest irradiation curative for NSCLC? 2) What are the contra-indications (anatomical or functional) to chest irradiation? 3) Does the addition of chemotherapy add an advantage to radiotherapy? 4) Does the addition of radiotherapy add an advantage to chemotherapy? 5) Is irradiation as effective as surgery for marginally resectable stage III? 6) How to best combine chemotherapy with radiotherapy: sequentially, concomitantly, as consolidation, as induction, as radiosensitiser? 7) In case of too advanced locoregional disease, is there a role for consolidation (salvage) local treatment (surgery or radiotherapy) after induction chemotherapy? 8) In 2005, what are the technical characteristics of an adequate radiotherapy

Management of acute COPD exacerbations in France: A qualitative survey in a private practice setting.

BackgroundThe current prevalence of chronic obstructive pulmonary disease (COPD) in France is estimated to be 2.6 million and is predicted to increase to 2.8 million by 2025. Presently, there is a lack of data on COPD management within the private healthcare setting. The aim of this study was to investigate the management of COPD exacerbations by pulmonologists within private practices in France.MethodsA prospective, online, qualitative survey was distributed to private practice pulmonologists in France. The survey covered all aspects of COPD management from diagnosis and therapeutic management, to secondary prevention and organization of care. Survey responses were collected between 27 January 2018 and 18 June 2018 and all data were summarized descriptively.ResultsThe survey had a response rate of 20.6%, with 116 out of 563 pulmonologists providing responses. Overall, 87.4% of respondents stated that the management of COPD represented over 15% of their total clinical activity. Most respondents indicated that they work closely with general practitioners and a large multidisciplinary team to manage patients with numerous comorbidities. Following a COPD exacerbation, the majority of respondents (78.4%) were in favor of using respiratory-connected devices (class 2a-connected medical device according to the French HAS classification and available on medical prescription) to assist with patient follow-up at home.ConclusionsCOPD management forms part of the core clinical activity for pulmonologists within the private practice setting in France. Patients with COPD generally have multiple comorbidities and are managed by a multidisciplinary team in line with French guidelines. The use of respiratory-connected devices was highlighted as an important new strategy for improving patient care following a COPD exacerbation

Symptomatic response to CPAP in obstructive sleep apnea versus COPD- obstructive sleep apnea overlap syndrome: Insights from a large national registry

Background: The symptomatic response to continuous positive airway pressure (CPAP) therapy in COPD-obstructive sleep apnea overlap syndrome (OVS) compared to OSA syndrome (OSA) alone has not been well studied so far. The aim of this study is to explore main differences in the clinical response to CPAP treatment in OVS compared to OSA alone. Study design and methods: Using prospective data from the French National Sleep Apnea Registry, we conducted an observational study among 6320 patients with moderate-to-severe OSA, available spirometry, and at least one follow-up visit under CPAP therapy. Results: CPAP efficacy measured on the residual apnea-hypopnea index and median adherence were similar between OVS and OSA patients. In both groups, the overall burden of symptoms related to sleep apnea improved with CPAP treatment. In a multivariable model adjusted for age, gender, body mass index, adherence to treatment and residual apnea-hypopnea index, OVS was associated with higher odds for persistent morning headaches (OR: 1.37 [95% CI; 1.04; 1.79]; P = 0.02), morning tiredness (OR: 1.33 [95% CI: 1.12; 1.59]; P&lt;0.01), daytime sleepiness (OR; 1.24 [95% CI: 1.4; 1.46]: P&lt;0.01) and exertional dyspnea (OR: 1.26 [95% CI: 1.00;1.58]; P = 0.04) when compared with OSA alone. Interpretation: CPAP therapy was effective in normalizing the apnea-hypopnea index and significantly improved OSA-related symptoms, regardless of COPD status. CPAP should be offered to patients with OVS on a trial basis as a significant improvement in OSA-related symptoms can be expected, although the range of response may be less dramatic than in OSA alone.</p

Clinical presentation and comorbidities of obstructive sleep apnea-COPD overlap syndrome

International audienceBackground: More advanced knowledge is needed on how COPD alters the clinical presentation of obstructive sleep apnea (OSA) and how the association of both diseases, known as 'overlap syndrome' (OVS), impacts on cardiovascular health.Objective: To investigate differences between patients with OVS and those with moderate-to-severe OSA alone.Methods: A cross-sectional study conducted in the French National Sleep Apnea Registry between January 1997 and January 2017. Univariable and multivariable logistic regression models were used to compare OVS versus OSA alone on symptoms and cardiovascular health.Results: 46,786 patients had moderate-to-severe OSA. Valid spirometry was available for 16,466 patients: 14,368 (87%) had moderate-to-severe OSA alone and 2098 (13%) had OVS. A lower proportion of OVS patients complained of snoring, morning headaches and excessive daytime sleepiness compared to OSA alone (median Epworth Sleepiness Scale score: 9 [interquartile range (IQR) 6-13] versus 10 (IQR 6-13), respectively; P <0.02). Similarly, a lower proportion of OVS patients (35.6% versus 39.4%, respectively; P <0.01) experienced sleepiness while driving. In contrast, 63.5% of the OVS population experienced nocturia compared to 58.0% of the OSA population (P<0.01). Apnea hypopnea index (36 [25; 52] vs 33.1 [23.3; 50]), oxygen desaturation index (28 [15; 48] vs 25.2 [14; 45]) and mean nocturnal SaO2 (92 [90; 93.8] vs 93 [91.3; 94]) were significantly more altered in the OVS group. Associated COPD had no effect on the prevalence of hypertension and stroke. After controlling for main confounders, COPD severity was associated in a dose-response relationship with a higher prevalence of coronary heart disease, heart failure and peripheral arteriopathy.Conclusions: In adults with moderate-to-severe OSA, OVS was minimally symptomatic, but exhibited higher odds for prevalent coronary heart disease, heart failure and peripheral arteriopathy

Obstructive Sleep Apnea: A Cluster Analysis at Time of Diagnosis

<div><p>Background</p><p>The classification of obstructive sleep apnea is on the basis of sleep study criteria that may not adequately capture disease heterogeneity. Improved phenotyping may improve prognosis prediction and help select therapeutic strategies. <i>Objectives</i>: This study used cluster analysis to investigate the clinical clusters of obstructive sleep apnea.</p><p>Methods</p><p>An ascending hierarchical cluster analysis was performed on baseline symptoms, physical examination, risk factor exposure and co-morbidities from 18,263 participants in the OSFP (French national registry of sleep apnea). The probability for criteria to be associated with a given cluster was assessed using odds ratios, determined by univariate logistic regression. <i>Results</i>: Six clusters were identified, in which patients varied considerably in age, sex, symptoms, obesity, co-morbidities and environmental risk factors. The main significant differences between clusters were minimally symptomatic versus sleepy obstructive sleep apnea patients, lean versus obese, and among obese patients different combinations of co-morbidities and environmental risk factors.</p><p>Conclusions</p><p>Our cluster analysis identified six distinct clusters of obstructive sleep apnea. Our findings underscore the high degree of heterogeneity that exists within obstructive sleep apnea patients regarding clinical presentation, risk factors and consequences. This may help in both research and clinical practice for validating new prevention programs, in diagnosis and in decisions regarding therapeutic strategies.</p></div
