Evolution in the Surgical Care of Patients With Non-Small Cell Lung Cancer in the Mid-South Quality of Surgical Resection Cohort.

ABSTRACT: Surgery is the most important curative treatment modality for patients with early-stage non-small cell lung cancer (NSCLC). We examined the pattern of surgical resection for NSCLC in a high incidence and mortality region of the United States over a 10-year period (2004-2013) in the context of a regional surgical quality improvement initiative. We abstracted patient-level data on all resections at 11 hospitals in 4 contiguous Dartmouth Hospital Referral Regions in North Mississippi, East Arkansas, and West Tennessee. Surgical quality measures focused on intraoperative practice, with emphasis on pathologic nodal staging. We used descriptive statistics and trend analyses to assess changes in practice over time. To measure the effect of an ongoing regional quality improvement intervention with a lymph node specimen collection kit, we used period effect analysis to compare trends between the preintervention and postintervention periods. Of 2566 patients, 18% had no preoperative biopsy, only 15% had a preoperative invasive staging test, and 11% underwent mediastinoscopy. The rate of resections with no mediastinal lymph nodes examined decreased from 48%-32% (P < 0.0001), whereas the rate of resections examining 3 or more mediastinal stations increased from 5%-49% (P < 0.0001). There was a significant period effect in the increase in the number of N1, mediastinal, and total lymph nodes examined (all P < 0.0001). A quality improvement intervention including a lymph node specimen collection kit shows early signs of having a significant positive effect on pathologic nodal examination in this population-based cohort. However, gaps in surgical quality remain.

Project description:BackgroundDyspnoea is common following surgical resection for non-small cell lung cancer (NSCLC). The effects range from reduced quality of life to impact on adjuvant therapy outcomes. Currently, dyspnoea beyond the immediate postoperative phase and risk factors are not well characterised. We hope to assess the evolution of patient-reported dyspnoea after anatomic lung resection and associated factors.MethodsSingle-centre cohort study with analysis on data collected longitudinally of 131 patients undergoing anatomic lung resections for NSCLC between September 2014 and December 2018. The European Organization for Research and Treatment Lung Cancer-specific Quality of Life Questionnaire Dyspnoea Scale was used to measure dyspnoea before and after surgery. Multivariable regression analysis was used to identify factors associated with clinically meaningful perioperative changes in dyspnoea at 6-12 months.ResultsMean Dyspnoea Scale scores preoperatively and 6-12 months after resection were 12.6 (standard deviation 17.4) and 17.9 (standard deviation 20.5), respectively. Of all patients 31% experienced a clinically meaningful increase in dyspnoea, defined as >10 points between Dyspnoea Scale scores preoperatively and at 6-12 months. Comparatively, 71% of patients without preoperative symptoms of dyspnoea developed a clinically meaningful increase of dyspnoea postoperatively. After adjusting the analysis for baseline factors and preoperative Dyspnoea Scale score, female sex remained the only patient factor associated with increased postoperative dyspnoea at 6-12 months after surgery (P=0.046). A total of 34% of patients reported increased dyspnoea after lobectomies and 9% after segmentectomies (P=0.014). Segmentectomy (as opposed to larger resections) was the only surgical factor associated with lower risk of increased dyspnoea (P=0.057).ConclusionsA clinically meaningful increase in dyspnoea is frequent after lung resection. Postoperative evolution of dyspnoea is non-predictable using objective baseline factors highlighting the importance of patient reported symptoms and involvement in clinical consultation.

Project description:BackgroundCigarette smoking is a risk factor for interstitial lung abnormalities (ILAs) and interstitial lung diseases (ILDs). Investigation defining the relationships between ILAs/ILDs and clinical, radiographic, and pathologic findings in smokers have been incomplete. Employing a cohort undergoing surgical resection for lung nodules/masses, we (1) define the prevalence of ILAs/ILDs, (2) delineate their clinical, radiographic and pathologic predictors, and (3) determine their associations with mortality.MethodsPatients undergoing resection of lung nodules/masses between 2017 and 2020 at a rural Appalachian, tertiary medical center were retrospectively investigated. Predictors for ILAs/ILDs and mortality were assessed using multivariate logistic regression analysis.ResultsIn the total study cohort of 352 patients, radiographic ILAs and ILDs were observed in 35.2% and 17.6%, respectively. Among ILA patterns, subpleural reticular changes (14.8%), non-emphysematous cysts, centrilobular (CL) ground glass opacities (GGOs) (8% each), and mixed CL-GGO and subpleural reticular changes (7.4%) were common. ILD patterns included combined pulmonary fibrosis emphysema (CPFE) (3.1%), respiratory bronchiolitis (RB)-ILD (3.1%), organizing pneumonitis (2.8%) and unclassifiable (4.8%). The group with radiographic ILAs/ILDs had a significantly higher proportion of ever smokers (49% vs. 39.9%), pack years of smoking (44.57 ± 36.21 vs. 34.96 ± 26.22), clinical comorbidities of COPD (35% vs. 26.5%) and mildly reduced diffusion capacity (% predicated 66.29 ± 20.55 vs. 71.84 ± 23). Radiographic centrilobular and paraseptal emphysema (40% vs. 22.2% and 17.6% vs. 9.6%, respectively) and isolated traction bronchiectasis (10.2% vs. 4.2%) were associated with ILAs/ILDs. Pathological variables of emphysema (34.9% vs. 18.5%), any fibrosis (15.9% vs. 4.6%), peribronchiolar metaplasia (PBM, 8% vs. 1.1%), RB (10.3% vs. 2.5%), and anthracosis (21.6% vs. 14.5%) were associated with ILAs/ILDs. Histologic emphysema showed positive correlations with any fibrosis, RB, anthracosis and ≥ 30 pack year of smoking. The group with ILAs/ILDs had significantly higher mortality (9.1% vs. 2.2%, OR 4.13, [95% CI of 1.84-9.25]).ConclusionsIn a rural cohort undergoing surgical resection, radiographic subclinical ILAs/ILDs patterns were highly prevalent and associated with ever smoking and intensity of smoking. The presence of radiographic ILA/ILD patterns and isolated honeycomb changes were associated with increased mortality. Subclinical ILAs/ILDs and histologic fibrosis correlated with clinical COPD as well as radiographic and pathologic emphysema emphasizing the co-existence of these pulmonary injuries in a heavily smoking population.

Project description:The objective of the current study was to analyze various patient-related factors related to patient-reported quality of overall and surgical care following surgical resection of lung or colorectal cancer.Between 2003 and 2005, 3,954 patients who underwent cancer-directed surgery for newly diagnosed lung (30.3%) or colorectal (69.7%) cancer were identified from a population- and health system-based survey of participants from multiple US regions. Factors associated with patient-perceived quality of overall and surgical care were analyzed with multivariable logistic regression models.Overall, 56.7% of patients reported excellent quality of overall care and 67.9% of patients reported excellent quality of surgical care; there was no difference by cancer type (P?>?0.05). Factors associated with lower likelihood to report excellent quality of overall and surgical care included female sex, minority race, and the presence of multiple comorbidities (all odds ratio [OR] <1, all P?<?0.05). Patients who had higher levels of education (overall quality: OR 1.62; surgical quality: OR 1.26), higher annual income (overall quality: OR 1.29; surgical quality: OR 1.23), and good physical function (overall quality: OR 1.35; surgical quality: OR 1.24) were all more likely to report excellent quality of overall and surgical care (all P?<?0.05). Furthermore, patients who reported their physician as having excellent communication skills (overall quality: OR 6.49; surgical quality: OR 3.74) as well as patients who perceived their cancer as likely curable (overall quality: OR 1.17; surgical quality: OR 1.11) were more likely to report excellent quality of overall and surgical care (all P?<?0.05).Patient-reported quality of care is associated with several factors including race, income, and educational status, as well as physician communication and patient perception of likelihood of cure. Future studies are needed to more closely examine patient-physician relationships and communication barriers, particularly among minority patients and those with lower income and educational status.
