RESUMO

BACKGROUND: Racial disparities in lung cancer screening (LCS) are well established. Black Veterans are among those at the highest risk for developing lung cancer but are less likely to complete LCS. We sought to identify barriers and facilitators to LCS uptake among Black Veterans. PATIENTS AND METHODS: A qualitative study using semistructured interviews was conducted with 32 Black Veterans to assess for barriers, facilitators, and contextual factors for LCS and strategies to improve screening. Veterans were purposively sampled by age, sex, and LCS participation status (ie, patients who received a low-dose CT [LDCT], patients who contacted the screening program but did not receive an LDCT, and patients who did not connect with the screening program nor receive an LDCT). Interview guides were developed using the Theoretical Domains Framework and Health Belief Model. Data were analyzed using rapid qualitative analysis. RESULTS: Barriers of LCS uptake among Black Veterans include self-reported low LCS knowledge and poor memory, attention, and decision processes associated with the centralized LCS process. Facilitators of LCS uptake among Black Veterans include social/professional role; identity and social influences; perceived susceptibility, threat, and consequences due to smoking status and military or occupational exposures; emotion, behavioral regulation, and intentions; and high trust in providers. Environmental context and resources (eg, transportation) and race and racism serve as contextual factors that did not emerge as having a major impact on LCS uptake. Strategies to improve LCS uptake included increased social messaging surrounding LCS, various forms of information dissemination, LCS reminders, balanced and repeated shared decision-making discussions, and streamlined referrals. CONCLUSIONS: We identified addressable barriers and facilitators for LCS uptake among Black Veterans that can help focus efforts to improve disparities in screening. Future studies should explore provider perspectives and test interventions to improve equity in LCS.

RESUMO

RATIONALE: Transbronchial lung cryobiopsy (TBLC) has emerged as a less invasive method to obtain a tissue diagnosis in patients with interstitial lung disease (ILD). The diagnostic yield of TBLC compared to surgical lung biopsy (SLB) remains uncertain. OBJECTIVES: The aim of this study was to determine the diagnostic accuracy of forceps transbronchial lung biopsy (TBLB) and TBLC compared to SLB when making the final diagnosis based on multidisciplinary discussion (MDD). METHODS: Patients enrolled in the study underwent sequential TBLB and TBLC followed immediately by SLB. De-identified cases, with blinding of the biopsy method, were reviewed by a blinded pathologist and then discussed at a multidisciplinary conference. MAIN RESULTS: Between August 2013 and October 2017, we enrolled 16 patients. The raw agreement between TBLC and SLB for the MDD final diagnosis was 68.75% with a Cohen's kappa of 0.6 (95% CI 0.39, 0.81). Raw agreement and Cohen's kappa of TBLB versus TBLC and TBLB versus SLB for the MDD final diagnosis were much lower (50%, 0.21 [95% CI 0, 0.42] and 18.75%, 0.08 [95% CI -0.03, 0.19], respectively). TBLC was associated with mild bleeding (grade 1 bleeding requiring suction to clear) in 56.2% of patients. CONCLUSIONS: In patients with ILD who have an uncertain type based on clinical and radiographic data and require tissue sampling to obtain a specific diagnosis, TBLC showed moderate correlation with SLB when making the diagnosis with MDD guidance. TBLB showed poor concordance with both TBLC and SLB MDD diagnoses.

RESUMO

BACKGROUND: Despite increased use of rigid bronchoscopy (RB) for therapeutic indications and recommendations from professional societies to use performance-based competency, an assessment tool has not been utilized to measure the competency of trainees to perform RB in clinical settings. OBJECTIVES: The aim of the study was to evaluate a previously developed assessment tool - Rigid Bronchoscopy Tool for Assessment of Skills and Competence (RIGID-TASC) - for determining the RB learning curve of interventional pulmonary (IP) trainees in the clinical setting and explore the variability of learning curve of trainees. METHODS: IP fellows at 4 institutions were enrolled. After preclinical simulation training, all RBs performed in patients were scored by faculty using RIGID-TASC until competency threshold was achieved. Competency threshold was defined as unassisted RB intubation and navigation through the central airways on 3 consecutive patients at the first attempt with a minimum score of 89. A regression-based model was devised to construct and compare the learning curves. RESULTS: Twelve IP fellows performed 178 RBs. Trainees reached the competency threshold between 5 and 24 RBs, with a median of 15 RBs (95% CI, 6-21). There were differences among trainees in learning curve parameters including starting point, slope, and inflection point, as demonstrated by the curve-fitting model. Subtasks that required the highest number of procedures (median = 10) to gain competency included ability to intubate at the first attempt and intubation time of <60 s. CONCLUSIONS: Trainees acquire RB skills at a variable pace, and RIGID-TASC can be used to assess learning curve of IP trainees in clinical settings.

RESUMO

Background: Accurate staging for small cell lung cancer (SCLC) is critical for determining appropriate therapy. The clinical impact of increasing PET adoption and stage migration is well described in non-small cell lung cancer but not in SCLC. The objective of this study was to evaluate temporal trends in PET staging and survival in the Veterans Affairs Central Cancer Registry and the impact of PET on outcomes. Patients and Methods: Patients diagnosed with SCLC from 2001 to 2010 were identified. PET staging, overall survival (OS), and lung cancer-specific survival (LCSS) were assessed over time. The impact of PET staging on OS and LCSS was assessed for limited-stage (LS) and extensive-stage (ES) SCLC. Results: From 2001 to 2010, PET use in a total of 10,135 patients with SCLC increased from 1.1% to 39.2%. Median OS improved for all patients (from 6.2 to 7.9 months), those with LS-SCLC (from 10.9 to 13.2 months), and those with ES-SCLC (from 5.0 to 7.0 months). Among staged patients, the proportion of ES-SCLC increased from 63.9% to 65.7%. Among 1,536 patients with LS-SCLC treated with concurrent chemoradiotherapy, 397 were staged by PET. In these patients, PET was associated with longer OS (median, 19.8 vs 14.3 months; hazard ratio [HR], 0.78; 95% CI, 0.68-0.90; P<.0001) and LCSS (median, 22.9 vs 16.7 months; HR, 0.74; 95% CI, 0.63-0.87; P<.0001) with multivariate adjustment and propensity-matching. In the 6,143 patients with ES-SCLC, PET was also associated with improved OS and LCSS. Conclusions: From 2001 to 2010, PET staging increased in this large cohort, with a corresponding relative increase in ES-SCLC. PET was associated with greater OS and LCSS for LS-SCLC and ES-SCLC, likely reflecting stage migration and stage-appropriate therapy. These findings emphasize the importance of PET in SCLC and support its routine use.

RESUMO

BACKGROUND: Malignant central airway obstruction (CAO) occurs in approximately 20-30% of patients with lung cancer and is associated with debilitating symptoms and poor prognosis. Multimodality therapeutic bronchoscopy can relieve malignant CAO, though carries risk. Evidence to guide clinicians regarding which patients may benefit from such interventions is sparse. We aimed to assess the clinical and radiographic predictors associated with therapeutic bronchoscopy success in relieving malignant CAO. METHODS: We reviewed all cases of therapeutic bronchoscopy performed for malignant CAO at our institution from January 2010-February 2017. Therapeutic bronchoscopy success was defined as establishing airway patency of > 50%. Patient demographics and baseline characteristics, oncology history, degree of airway obstruction, procedural interventions, and complications were compared between successful and unsuccessful groups. Univariate and multivariate logistic regression identified the significant clinical and radiographic predictors for therapeutic success. The corresponding simple and conditional odds ratio were calculated. A time-to-event analysis with Kaplan-Meier plots was performed to estimate overall survival. RESULTS: During the study period, 301 therapeutic bronchoscopies were performed; 44 (14.6%) were considered unsuccessful. Factors associated with success included never vs current smoking status (OR 5.36, 95% CI:1.45-19.74, p = 0.010), patent distal airway on CT imaging (OR 15.11, 95% CI:2.98-45.83, p < 0.0001) and patent distal airway visualized during bronchoscopy (OR 10.77, 95% CI:3.63-31.95, p < 0.001) in univariate analysis. Along with patent distal airway on CT imaging, increased time from radiographic finding to therapeutic bronchoscopy was associated with lower odds of success in multivariate analysis (OR 0.96, 95% CI:0.92-1.00, p = 0.048). Median survival was longer in the successful group (10.2 months, 95% CI:4.8-20.2) compared to the unsuccessful group (6.1 months, 95% CI:2.1-10.8, log rank p = 0.015). CONCLUSIONS: Predictors associated with successful therapeutic bronchoscopy for malignant CAO include distal patent airway visualized on CT scan and during bronchoscopy. Odds of success are higher in non-smokers, and with decreased time from radiographic finding of CAO to intervention.

RESUMO

RATIONALE: Patients with malignant pleural effusions have significant dyspnea and shortened life expectancy. Indwelling pleural catheters allow patients to drain pleural fluid at home and can lead to autopleurodesis. The optimal drainage frequency to achieve autopleurodesis and freedom from catheter has not been determined. OBJECTIVES: To determine whether an aggressive daily drainage strategy is superior to the current standard every other day drainage of pleural fluid in achieving autopleurodesis. METHODS: Patients were randomized to either an aggressive drainage (daily drainage; n = 73) or standard drainage (every other day drainage; n = 76) of pleural fluid via a tunneled pleural catheter. MEASUREMENTS AND MAIN RESULTS: The primary outcome was the incidence of autopleurodesis following the placement of the indwelling pleural catheters. The rate of autopleurodesis, defined as complete or partial response based on symptomatic and radiographic changes, was greater in the aggressive drainage arm than the standard drainage arm (47% vs. 24%, respectively; P = 0.003). Median time to autopleurodesis was shorter in the aggressive arm (54 d; 95% confidence interval, 34-83) as compared with the standard arm (90 d; 95% confidence interval, 70 to nonestimable). Rate of adverse events, quality of life, and patient satisfaction were not significantly different between the two arms. CONCLUSIONS: Among patients with malignant pleural effusion, daily drainage of pleural fluid via an indwelling pleural catheter led to a higher rate of autopleurodesis and faster time to liberty from catheter. Clinical trial registered with www.clinicaltrials.gov (NCT 00978939).

RESUMO

RATIONALE: Central airway stenosis (CAS) after lung transplantation has been attributed in part to chronic airway ischemia; however, little is known about the time course or significance of large airway hypoxia early after transplantation. OBJECTIVES: To evaluate large airway oxygenation and hypoxic gene expression during the first month after lung transplantation and their relation to airway complications. METHODS: Subjects who underwent lung transplantation underwent endobronchial tissue oximetry of native and donor bronchi at 0, 3, and 30 days after transplantation (n = 11) and/or endobronchial biopsies (n = 14) at 30 days for real-time polymerase chain reaction of hypoxia-inducible genes. Patients were monitored for 6 months for the development of transplant-related complications. MEASUREMENTS AND MAIN RESULTS: Compared with native endobronchial tissues, donor tissue oxygen saturations (Sto2) were reduced in the upper lobes (74.1 ± 1.8% vs. 68.8 ± 1.7%; P < 0.05) and lower lobes (75.6 ± 1.6% vs. 71.5 ± 1.8%; P = 0.065) at 30 days post-transplantation. Donor upper lobe and subcarina Sto2 levels were also lower than the main carina (difference of -3.9 ± 1.5 and -4.8 ± 2.1, respectively; P < 0.05) at 30 days. Up-regulation of hypoxia-inducible genes VEGFA, FLT1, VEGFC, HMOX1, and TIE2 was significant in donor airways relative to native airways (all P < 0.05). VEGFA, KDR, and HMOX1 were associated with prolonged respiratory failure, prolonged hospitalization, extensive airway necrosis, and CAS (P < 0.05). CONCLUSIONS: These findings implicate donor bronchial hypoxia as a driving factor for post-transplantation airway complications. Strategies to improve airway oxygenation, such as bronchial artery re-anastomosis and hyperbaric oxygen therapy merit clinical investigation.

RESUMO

BACKGROUND: Central airway stenosis (CAS) is common after lung transplantation and causes significant post-transplant morbidity. It is often preceded by extensive airway necrosis, related to airway ischemia. Hyperbaric oxygen therapy (HBOT) is useful for ischemic grafts and may reduce the development of CAS. METHODS: The purpose of this study was to determine whether HBOT could be safely administered to lung transplant patients with extensive necrotic airway plaques. Secondarily, we assessed any effects of HBOT on the incidence and severity of CAS. Patients with extensive necrotic airway plaques within 1-2 months after lung transplantation were treated with HBOT along with standard care. These patients were compared with a contemporaneous reference group with similar plaques who did not receive HBOT. RESULTS: Ten patients received HBOT for 18.5 (interquartile range, IQR 11-20) sessions, starting at 40.5 (IQR 34-54) days after transplantation. HBOT was well tolerated. Incidence of CAS was similar between HBOT-treated patients and reference patients (70% vs 87%, respectively; P=.34), but fewer stents were required in HBOT patients (10% vs 56%, respectively; P=.03). CONCLUSIONS: This pilot study is the first to demonstrate HBOT safety in patients who develop necrotic airway plaques after lung transplantation. HBOT may reduce the need for airway stent placement in patients with CAS.

RESUMO

BACKGROUND: Central airway obstruction (CAO) occurs in patients with primary or metastatic lung malignancy and nonmalignant pulmonary disorders and results in significant adverse effects on respiratory function and quality of life. OBJECTIVES: The objective of this study was to assess the effect of therapeutic bronchoscopic interventions on spirometry, dyspnea, quality of life, and survival in patients with CAO. METHODS: We prospectively studied patients who underwent therapeutic rigid bronchoscopy for CAO. Spirometry, San Diego Shortness of Breath questionnaire (SOBQ), and SF-36 questionnaire responses were obtained before the procedure and at follow-up 6-8 weeks after the procedure. RESULTS: Fifty-three patients (24 malignant and 29 nonmalignant CAO), who underwent successful rigid bronchoscopic intervention, were enrolled. Airway stent placement and various debulking techniques including mechanical debridement and heat therapy were used. After bronchoscopy, there was a significant increase in forced vital capacity (2.2 ± 0.91 l before, 2.7 ± 0.80 l after, p = 0.009) and forced expiratory volume at 1 s (1.4 ± 0.60 l before, 1.8 ± 0.67 l after, p = 0.002). The SOBQ score improved from 55.8 ± 30.1 before the procedure to 37.9 ± 27.25 after the procedure (p = 0.002). In the SF-36, there was an improvement in almost all domains, with statistically significant improvement seen in several domains. Benefits were seen independent of the etiology of CAO, site of intervention or stent placement. The patients with malignant CAO, in whom airway patency could not be achieved, had a poor survival. CONCLUSIONS: Alleviation of CAO with therapeutic rigid bronchoscopy results in improvement in spirometry, shortness of breath, quality of life, and survival.

RESUMO

The biopsy collection data from two lung cancer trials that required fresh tumor samples be obtained for microarray analysis were reviewed. In the trial for advanced disease, microarray data were obtained on 50 patient samples, giving an overall success rate of 60.2%. The majority of the specimens were obtained through CT-guided lung biopsies (N = 30). In the trial for early-stage patients, 28 tissue specimens were collected from excess tumor after surgical resection with a success rate of 85.7%. This tissue procurement program documents the feasibility in obtaining fresh tumor specimens prospectively that could be used for molecular testing.

RESUMO

BACKGROUND: Direct comparison of tumor microenvironment of matched lung cancer biopsies and pleural effusions (PE) from the same patients is critical in understanding tumor biology but has not been performed. This is the first study to compare the lung cancer and PE microenvironment by single-cell RNA sequencing (scRNA-seq). METHODS: Matched lung cancer biopsies and PE were obtained prospectively from ten patients. We isolated CD45+ cells and performed scRNA-seq to compare the biopsies and PE. RESULTS: PE had a higher proportion of CD4+ T cells but lower proportion of CD8+ T cells (False detection rate, FDR = 0.0003) compared to biopsies. There was a higher proportion of naïve CD4+ T cells (FDR = 0.04) and naïve CD8+ T cells (FDR = 0.0008) in PE vs. biopsies. On the other hand, there was a higher proportion of Tregs (FDR = 0.04), effector CD8+ (FDR = 0.006), and exhausted CD8+ T cells (FDR = 0.01) in biopsies. The expression of inflammatory genes in T cells was increased in biopsies vs. PE, including TNF, IFN-É£, IL-1R1, IL-1R2, IL-2, IL-12RB2, IL-18R1, and IL-18RAP (FDR = 0.009, 0.013, 0.029, 0.043, 0.009, 0.013, 0.004, and 0.003, respectively). The gene expression of exhaustion markers in T cells was also increased in tumor biopsies including PDCD1, CTLA4, LAG 3, HAVCR2, TIGIT, and CD160 (FDR = 0.008, 0.003, 0.002, 0.011, 0.006, and 0.049, respectively). CONCLUSIONS: There is a higher proportion of naïve T cells and lower proportion of exhausted T cells and Tregs in PE compared to lung cancer biopsies, which can be leveraged for prognostic and therapeutic applications.

RESUMO

Lung cancer screening (LCS) decreases lung cancer related mortality among high-risk people who smoke cigarettes and has been endorsed by the US Preventive Services Task Force (USPSTF) since 2013. However, adoption of LCS has been limited, and disparities in LCS among racially and ethnically minoritized groups have become apparent. While recommendations to improve disparities in LCS have been made, there is a lack of information on how these recommendations have been implemented and their relative effectiveness in improving screening disparities. This scoping review addresses this knowledge gap by examining interventions that have been implemented to improve LCS among racially and ethnically minoritized groups in the United States. A comprehensive search of MEDLINE (via PubMed), EMBASE (via Elsevier), CINAHL Complete (via EBSCO), and Scopus (via Elsevier), for articles from the period 1 January 2010 through 22 October 2021 was completed. Out of 17,045 references screened, only 11 studies describing an intervention to improve disparities in LCS were identified, underscoring the dearth of data on established interventions. The interventions discussed could be categorized into three groups -- patient level (n = 3), clinic/institution level (n = 3), and community level (n = 5) interventions. Of those studies reporting effectiveness data (n = 8), there was substantial heterogeneity in the outcomes measured and their relative effectiveness. We found that interventions which streamlined the LCS process at the level of a single clinic or institution were the most effective in improving LCS. Community-level interventions that focused on engagement and education had the greatest potential to target racially and ethnically minoritized groups. Our study underscores the need for more robust research on addressing barriers to LCS by identifying effective patient, clinic, and community-level interventions to improve LCS disparities and the need for potential standardization of intervention effectiveness outcomes.

RESUMO

Importance: Racial disparities in lung cancer screening (LCS) are often ascribed to barriers such as cost, insurance status, access to care, and transportation. Because these barriers are minimized within the Veterans Affairs system, there is a question of whether similar racial disparities exist within a Veterans Affairs health care system in North Carolina. Objectives: To examine whether racial disparities in completing LCS after referral exist at the Durham Veterans Affairs Health Care System (DVAHCS) and, if so, what factors are associated with screening completion. Design, Setting, and Participants: This cross-sectional study assessed veterans referred to LCS between July 1, 2013, and August 31, 2021, at the DVAHCS. All included veterans self-identified as White or Black and met the US Preventive Services Task Force eligibility criteria as of January 1, 2021. Participants who died within 15 months of consultation or who were screened before consultation were excluded. Exposures: Self-reported race. Main Outcomes and Measures: Screening completion was defined as completing computed tomography for LCS. The associations among screening completion, race, and demographic and socioeconomic risk factors were assessed using logistic regression models. Results: A total of 4562 veterans (mean [SD] age, 65.4 [5.7] years; 4296 [94.2%] male; 1766 [38.7%] Black and 2796 [61.3%] White) were referred for LCS. Of all veterans referred, 1692 (37.1%) ultimately completed screening; 2707 (59.3%) never connected with the LCS program after referral and an informational mailer or telephone call, indicating a critical point in the LCS process. Screening rates were substantially lower among Black compared with White veterans (538 [30.5%] vs 1154 [41.3%]), with Black veterans having 0.66 times lower odds (95% CI, 0.54-0.80) of screening completion after adjusting for demographic and socioeconomic factors. Conclusions and Relevance: This cross-sectional study found that after referral for initial LCS via a centralized program, Black veterans had 34% lower odds of LCS screening completion compared with White veterans, a disparity that persisted even after accounting for numerous demographic and socioeconomic factors. A critical point in the screening process was when veterans must connect with the screening program after referral. These findings may be used to design, implement, and evaluate interventions to improve LCS rates among Black veterans.

RESUMO

BACKGROUND: Pleural cytology is currently used to assess targetable mutations in patients with advanced lung adenocarcinoma. However, it is fraught with low diagnostic yield. RESEARCH QUESTION: Can pleural cell-free DNA (cfDNA) be used to assess targetable mutations in lung adenocarcinoma patients with malignant pleural effusions (MPE)? STUDY DESIGN AND METHODS: Patients with lung adenocarcinoma MPE were recruited prospectively between January 2017 and September 2021. Oncogenic mutations were assessed by treating providers using pleural fluid cytology or lung cancer biopsies. Pleural and plasma cfDNA were used to assess the mutations using next-generation sequencing (NGS). RESULTS: Fifty-four pleural fluid samples were collected from 42 patients. The diagnostic yield to detect oncogenic mutations for pleural cfDNA, pleural cytology, biopsy, and plasma cfDNA was 49/54 (90.7%), 16/33 (48.5%), 22/25 (88%), and 24/32 (75%), respectively, P < .001. The agreement of mutations in positive samples between pleural cfDNA and pleural cytology was 100%, whereas the agreement of pleural cfDNA with biopsies was 89.4%. The median concentration (interquartile range) of pleural cfDNA was higher than plasma: 28,444 (4,957-67,051) vs 2,966.5 (2,167-5,025) copies of amplifiable DNA per mL, P < .01. Median of 5 mL (interquartile range, 4.5-5) of pleural fluid supernatant was adequate for cfDNA testing. INTERPRETATION: The diagnostic yield of pleural cfDNA NGS for oncogenic mutations in lung adenocarcinoma patients is comparable to tumor biopsies and higher than pleural cytology and plasma cfDNA. The pleural cfDNA can be longitudinally collected, can be readily incorporated in clinical workflow, and may decrease the need for additional biopsies.

RESUMO

PURPOSE: Few programs exist to address persistent impairment in functional status, quality of life, and mental health in lung cancer survivors. We aimed to determine whether a 12-wk multimodal survivorship program imparts clinical benefit. METHODS: Any patient at the Durham Veterans Affairs Medical Center with lung cancer and a Karnofsky score of ≥60 could participate. Chronic obstructive pulmonary disease medications were optimized at the enrollment visit. Participants with a Hospital Anxiety and Depression Scale (HADS) score of >8 were offered pharmacotherapy and mental health referral. Participants did home-based exercise with a goal of 1 hr/d, 5 d/wk. They were called weekly to assess exercise progress and review depression/anxiety symptoms. Participants were offered pharmacotherapy for smoking cessation. RESULTS: Twenty-three (50%) of the first 46 enrollees completed the full 12-wk program. Paired changes from enrollment to completion (mean ± SD) were observed in 6-min walk test (73.6 ± 96.9 m, P = .002), BODE (Body mass index, airflow Obstruction, Dyspnea, and Exercise) index (-1.45 ± 1.64 points, P < .001), Duke Activity Status Index (3.84 ± 7.12 points, P = .02), Fried Frailty Index (-0.588 ± 0.939 points, P = .02), modified Medical Research Council dyspnea scale (-0.619 ± 1.284 points, P = .04), Functional Assessment of Cancer Therapy-Lung Emotional subscale score (1.52 ± 2.96 points, P = .03), HADS total score (-2.63 ± 4.34 points, P = .02), and HADS Anxiety subscale score (-1.47 ± 2.29 points, P = .01). CONCLUSIONS: A comprehensive Lung Cancer Survivorship Program provides clinically meaningful improvements in functional status, quality of life, and mental health.
