Impact of smoking status and chronic obstructive pulmonary disease on pulmonary complications post lung cancer surgery.

ABSTRACT:

Introduction

Smoking and chronic obstructive pulmonary disease (COPD) are associated with an increased risk of post-operative pulmonary complications (PPCs) following lung cancer resection. It remains unclear whether smoking cessation reduces this risk.

Methods

Retrospective review of a large, prospectively collected database of over 1000 consecutive resections for lung cancer in a quaternary lung cancer centre over a 23-year period.

Results

One thousand and thirteen patients underwent curative-intent lobectomy or pneumonectomy between 1995 and 2018. Three hundred and sixty-two patients (36%) were ex-smokers, 314 (31%) were current smokers and 111 (11%) were never smokers. A pre-operative diagnosis of COPD was present in 57% of current smokers, 57% of ex-smokers and 20% of never smokers. Just over 25% of patients experienced a PPC. PPCs were more frequent in current smokers compared to never smokers (27% vs 17%, p = 0.036), however, no difference was seen between current and ex-smokers (p = 0.412) or between never and ex-smokers (p = 0.113). Those with a diagnosis of COPD, independent of smoking status, had a higher frequency of both PPCs (65% vs 35%, p<0.01) and overall complications (60% vs 40%, p<0.01) as well as a longer length of hospital stay (10 vs 9 days, p<0.01).

Conclusion

Smoking and COPD are both associated with a higher rate of PPCs post lung cancer resection. COPD, independent of smoking status, is also associated with an increased overall post-operative complication rate and length of hospital stay. An emphasis on COPD treatment optimisation, rather than smoking cessation in isolation, may help improve post-operative outcomes.

Project description:ObjectivesInhaled corticosteroids (ICS) reduce exacerbation rates and the decline in lung function in people with chronic obstructive pulmonary disease (COPD). There is evidence that smoking causes 'steroid resistance' and thus reduces the effect of ICS. This systematic review aimed to investigate the effect of smoking on efficacy of ICS in COPD in terms of lung function and exacerbation rates.DesignSystematic review.Data sourcesAn electronic database search of PubMed, Ovid MEDLINE, Ovid Embase and Cochrane Library (January 2000 to January 2020).Eligibility criteriaFully published randomised controlled trials (RCTs), in the English language, evaluating the use of ICS in COPD adults that stratified the participants by smoking status. Trials that included participants with asthma, lung cancer and pneumonia were excluded. The primary outcome measures were changes in lung function and yearly exacerbation rates.Data extraction and synthesisTwo independent reviewers extracted data and assessed risk of bias using the Cochrane Collaboration's tool.ResultsSeven studies were identified. Four trials (17 892 participants) recorded change in forced expiratory volume in one second (FEV1) from baseline to up to 30 months after starting treatment. Heavier smokers (>36 pack years) using ICS had a greater decline in FEV1 that ranged from -22 mL to -75 mL in comparison to lighter smokers. Smokers using ICS had mixed results in FEV1 change: -8 mL to +77 mL in comparison to ex-smokers. Four trials (21 270 participants) recorded difference in COPD exacerbation rates at 52 weeks. The rate ratios favoured more exacerbations in ICS users who were current or heavier smokers than those who were ex-smokers or lighter smokers (0.81 to 0.99 vs 0.92 to 1.29).ConclusionsIn COPD, heavier or current smokers do not gain the same benefit from ICS use on lung function and exacerbation rates as lighter or ex-smokers do, however effects may not be clinically important.Prospero registration numberCRD42019121833.

Project description:INTRODUCTION:Chronic obstructive pulmonary disease (COPD) is a tobacco-related disease associated with several comorbid conditions, including elevated rates of depression and anxiety. Psychological factors that commonly underlie nicotine dependence, depression, and anxiety may represent novel treatment targets, but have not yet been examined among patientswith COPD. We assessed three psychological factors-anxiety sensitivity (AS; fear of anxiety-related sensations), distress intolerance (DI; inability to withstand distressing states), and anhedonia (Anh; diminished sense of pleasure or interest)-in relation to smoking status, COPD symptom impact, and negative response to COPD symptoms. METHODS:We conducted a single-session laboratory assessment with 37 patients with COPD (17 current daily smokers and 20 former smokers). All participants completed self-report measures of psychological factors, COPD symptom impact, response to COPD symptoms, and anxiety and depression symptoms. RESULTS:Current versus former smokers with COPD reported higher levels of AS, DI, and Anh. In univariate regression models, AS, DI, and Anh were each associated with greater COPD symptom impact and breathlessness catastrophizing. Only AS remained a significant predictor of COPD symptom impact and breathlessness catastrophizing after adjusting for general depression and anxiety symptoms. CONCLUSIONS:Our preliminary study is the first to assess AS, DI, and Anh among patients with COPD. These psychological factors were elevated among current smokers and associated with more negative disease impact, suggesting their potential utility as treatment targets within this clinical population. IMPLICATIONS:While elevated rates of anxiety and depression among patients with COPD have been wellcharacterized, few studies have specifically addressed the causal, modifiable psychological factors that may underlie these disorders. Our preliminary findings demonstrate associations of three psychological factors-AS, DI, and Anh-with smoking status, COPD symptom impact, and negative reaction to symptoms. Cognitive-behavioral interventions targeted to these psychological factors may improve smoking cessation outcomes and disease adjustment among patients with COPD.
