Untapping the Prognostic Value of Patient-Generated Health Data in Locally Advanced Non-small Cell Lung Cancer.

BACKGROUND: Patient-generated health data (PGHD), which includes patient-reported outcomes (PROs) and wearable device data, may have prognostic value for cancer patients. We tested that hypothesis using data from several prospective trials where patients with locally advanced non-small cell lung cancer (LA-NSCLC) were treated with definitive chemoradiotherapy. METHODS: Cox proportional hazards models were utilized to identify the baseline patient-reported symptom that best predicted progression-free survival (PFS) duration in a trial that involved PRO-CTCAE collection (Cohort 1). Using data from trials that included EORTC QLQ-C30 questionnaires and wearable devices (Cohort 2), the same symptom was tested as a predictor of PFS. Baseline physical inactivity was also tested as a predictor of PFS. A simple risk stratification tool utilizing PROs and physical activity was proposed. RESULTS: In Cohort 1 (n = 50), anorexia was the only pretreatment PRO that was significantly associated with PFS after Bonferroni correction (HR = 3.94, P = .002). In Cohort 2 (n = 58), baseline anorexia was also significantly associated with PFS (HR = 2.48, P = .018), as was physical inactivity (HR = 3.11, P < .001). Median PFS duration for patients in Cohort 2 with anorexia or physical inactivity was 6 months, compared to 18 months for other patients (HR = 3.08, P < .001). Median overall survival duration for patients with anorexia or physical inactivity was 19 months, compared to 65 months for other patients (HR = 2.44, P = .021). CONCLUSION: PGHD, including PROs and wearable device data, can provide valuable prognostic information for LA-NSCLC patients treated with definitive chemoradiotherapy. These findings should be validated using larger datasets.

Proceedings of the 1st biannual bridging the gaps in lung cancer conference.

Lung cancer is the leading cause of cancer death in the US and globally. The mortality from lung cancer has been declining, due to a reduction in incidence and advances in treatment. Although recent success in developing targeted and immunotherapies for lung cancer has benefitted patients, it has also expanded the complexity of potential treatment options for health care providers. To aid in reducing such complexity, experts in oncology convened a conference (Bridging the Gaps in Lung Cancer) to identify current knowledge gaps and controversies in the diagnosis, treatment, and outcomes of various lung cancer scenarios, as described here. Such scenarios relate to biomarkers and testing in lung cancer, small cell lung cancer, EGFR mutations and targeted therapy in non-small cell lung cancer (NSCLC), early-stage NSCLC, KRAS/BRAF/MET and other genomic alterations in NSCLC, and immunotherapy in advanced NSCLC.

Role of anticoagulation therapy in modifying stroke risk associated with new-onset atrial fibrillation after non-cardiac surgery.

The role of antithrombotic therapy in the prevention of ischemic stroke after non-cardiac surgery is unclear. In this study, we tested the hypothesis that the association of new-onset postoperative atrial fibrillation (POAF) on ischemic stroke can be mitigated by postoperative oral anticoagulation therapy. Of 251,837 adult patients (155,111 female (61.6%) and 96,726 male (38.4%)) who underwent non-cardiac surgical procedures at two sites, POAF was detected in 4,538 (1.8%) patients. The occurrence of POAF was associated with increased 1-year ischemic stroke risk (3.6% versus 2.3%; adjusted risk ratio (RRadj) = 1.60 (95% confidence interval (CI): 1.37-1.87), P < 0.001). In patients with POAF, the risk of developing stroke attributable to POAF was 1.81 (95% CI: 1.44-2.28; P < 0.001) without oral anticoagulation, whereas, in patients treated with anticoagulation, no significant association was observed between POAF and stroke (RRadj = 1.04 (95% CI: 0.71-1.51), P = 0.847, P for interaction = 0.013). Furthermore, we derived and validated a computational model for the prediction of POAF after non-cardiac surgery based on demographics, comorbidities and procedural risk. These findings suggest that POAF is predictable and associated with an increased risk of postoperative ischemic stroke in patients who do not receive postoperative anticoagulation.

Advancing neoadjuvant therapies in resectable non-small cell lung cancer: implications for novel treatment strategies and biomarker discovery.

The delivery of neoadjuvant and perioperative therapies for non-small cell lung cancer has been radically altered by significant advances and by the incorporation of targeted therapies as well as immune checkpoint inhibitors alone or alongside conventional chemotherapy. This evolution has been particularly notable in the incorporation of immunotherapy and targeted therapy into the treatment of resectable NSCLC, where recent FDA approvals of drugs such as nivolumab and pembrolizumab, in combination with platinum doublet chemotherapy, have led to considerable improvements in pathological complete response rates and the potential for enhanced long-term survival outcomes. This review emphasizes the growing importance of biomarkers in optimizing treatment selection and explores the impact of emerging studies that challenge existing treatment paradigms and investigate novel therapeutic combinations poised to redefine standard of care practices. Furthermore, the discussion extends to the unmet needs within perioperative treatment assessment and prognostication, highlighting the prospective value of biomarkers in evaluating treatment responses and prognosis.

Trends and Disparities in Robotic Surgery Utilization for Non-Small Cell Lung Cancer.

INTRODUCTION: Robotic surgery has become an increasingly utilized approach for resectable lung cancer. However, availability may be limited for certain patient populations, underscoring inequity in access to innovative surgical techniques. We hypothesize that there is an association between social determinants of health and robotic surgery utilization for resectable non-small cell lung cancer (NSCLC). METHODS: We queried the National Cancer Database (2010-2019) for patients with clinical stage I-III NSCLC who underwent resection, stratifying the cohort based on surgical technique. Multivariable logistic regression analysis was performed to identify associations between sociodemographic and clinicopathologic factors and the robotic approach. RESULTS: Among the 226,455 clinical stage I-III NSCLC patients identified, 34,059 (15%) received robotic resections, 78,039 (34.5%) underwent thoracoscopic resections, and 114,357 (50.5%) had open resections. Robotic surgery utilization increased from 3.1% in 2010 to 34% in 2019 (P < 0.001). Despite this, after adjusting by clinical stage, extent of resection, site of tumor, and receipt of neoadjuvant therapy, multivariable analysis revealed various sociodemographic and treatment facility factors that were associated with underutilization of this approach: lack of insurance (adjusted odds ratio [aOR] 0.83, 95% confidence interval [CI] 0.73-0.93), lower income brackets (aOR 0.93, 95% CI 0.91-0.96), provincial settings (urban aOR 0.79, 95% CI 0.76-0.82; rural aOR 0.57, 95% CI 0.51-0.64), and treatment at community centers (comprehensive community cancer programs aOR 0.73, 95% CI 0.70-0.75; community cancer programs aOR 0.51, 95% CI 0.47-0.55). CONCLUSIONS: This study suggests that disparities in determinants of health influence accessibility to robotic surgery for resectable NSCLC. Identification of these gaps is crucial to target vulnerable sectors of the population in promoting equality and uniformity in surgical treatment.

Pneumonectomy for non-small cell lung cancer. A National Cancer Database analysis of geographic and temporal trends, outcomes, and associated factors.

BACKGROUND: The circumstances under which pneumonectomy should be performed are controversial. This study aims to investigate national trends in pneumonectomy use to determine which patients, in what geographic areas, and under what clinical circumstances pneumonectomy is performed in the United States. METHODS: We queried the National Cancer Database and included all patients undergoing anatomic surgical resection for non-small cell lung cancer (2015-2020). The association between demographic and clinical factors and the use of pneumonectomy were investigated. RESULTS: Who: A total of 128,421 patients were identified, of whom 738 (0.6%) underwent pneumonectomy. Those patients were younger (median 65 vs 68 years, P < .001), more often male (59.9% vs 44.9%, P < .001), more likely to be below median income level (44.2% vs 38.6%, P = .002), and more likely to have lower education indicators (53% vs 48.6%, P = .02) than those who underwent other anatomic resections. Notably, there was a decreasing trend in pneumonectomy use during the study period (0.9% down to 0.4%, P < .001). Where: Patients undergoing pneumonectomy were less likely to live in metropolitan areas (77.9% vs 81.7%, P = .008) and to live closer (<12 miles) to their treating facility (45% vs 49%, P = .02). Regional geographic differences also were identified (P < .001). Why: Patients who underwent pneumonectomy were more likely to have received neoadjuvant therapy (20.6% vs 5.3%, P < .001), to be clinically N (+) (39.3% vs 12.3%, P < .001), and to have more advanced tumors (cT3-4: 46.3% vs 11.3%, P < .001). CONCLUSION: Although primarily driven by advanced oncologic features, socioeconomic and geographic factors also were associated independently with the use of pneumonectomy. Standardizing pneumonectomy indications nationwide is crucial to prevent widening outcome gaps for patients with lung cancer.

The Representation of Women Moderators at The Society of Thoracic Surgeons Annual Meeting.

BACKGROUND: Recently, there has been an increase in the representation of women within the cardiothoracic surgery workforce, with discussions about gender equity garnering interest. We sought to identify whether this increase is accompanied by commensurate selection for representation at national meetings. METHODS: Online archives of The Society of Thoracic Surgeons (STS) Annual Meetings were reviewed from 2015 to 2024. Data regarding the moderator's gender were abstracted. The gender distribution of moderators across the various session categories was surveyed, and subgroup analyses were performed. RESULTS: During the years of study, the STS Annual Meeting Taskforce selected 983 moderators to participate in the conference, including 218 women. The representation of women moderators demonstrated a favorable, upward trend. In 2015, 12.1% of moderators were women, with a consistent rate from 2015 to 2018. There was a noticeable rise in invited women moderators in 2019, with 25.4% of moderators being women. This proportion increased to 36.9% women in 2024. General Thoracic sessions have consistently included a greater percentage of women moderators compared with other sessions. Other topic areas, such as Education and Quality Improvement and Critical Care, transitioned to greater representation of women in recent years. CONCLUSIONS: There has been an increase over time in women moderators selected for participation in the STS Annual Meeting, with progress in gender diversity seen in most session types. Although the overall proportion of women within cardiothoracic surgery remains low, the STS has increasingly worked toward encouraging inclusivity. Efforts to further support well-rounded representation are of important benefit.

Perioperative Immunotherapy for Non-Small Cell Lung Cancer: Practical Application of Emerging Data and New Challenges.

Immune checkpoint inhibition, with or without chemotherapy, is an established standard of care for metastatic non-small cell lung cancer (NSCLC). For locally advanced NSCLC treated with chemoradiotherapy, consolidation immunotherapy has dramatically improved outcomes. Recently, immunotherapy has also been established as a valuable component of treatment for resectable NSCLC with pembrolizumab, atezolizumab, and nivolumab all approved for use in this setting. As more results read out from ongoing perioperative clinical trials, navigating treatment options will likely become increasingly complex for the practicing oncologist. In this paper, we distill key outcomes from major perioperative trials and highlight current knowledge gaps. In addition, we provide practical considerations for incorporating perioperative immunotherapy into the clinical management of operable NSCLC.

Resection of the Primary Tumor and Survival in Patients with Single-Site Synchronous Oligometastatic Non-Small Cell Lung Cancer: Propensity-Matched Analysis of the National Cancer Database.

BACKGROUND: Local therapy for the primary tumor is postulated to remove resistant cancer cells as well as immunosuppressive cells from the tumor microenvironment, potentially improving response to systemic therapy (ST). We sought to determine whether resection of the primary tumor was associated with overall survival (OS) in a multicentric cohort of patients with single-site synchronous oligometastatic non-small cell lung cancer. STUDY DESIGN: Using the National Cancer Database (2018 to 2020), we evaluated patients with clinical stage IVA disease who received ST and stratified the cohort based on receipt of surgery for the primary tumor (S). We used multivariable and propensity score-matched analysis to study factors associated with S (logistic regression) and OS (Cox regression and Kaplan-Meier), respectively. RESULTS: Among 12,215 patients identified, 2.9% (N = 349) underwent S and 97.1% (N = 11,886) ST (chemotherapy or immunotherapy) without surgery. Patients who underwent S were younger, more often White, had higher income levels, were more likely to have private insurance, and were more often treated at an academic facility. Among those who received S, 22.9% (N = 80) also underwent resection of the distant metastatic site. On multivariable analysis, metastasis to bone, N+ disease, and higher T-stages were independently associated with less S. On Cox regression, S and resection of the metastatic site were associated with improved survival (hazard ratio 0.67, 95% CI 0.56 to 0.80 and hazard ratio 0.80, 95% CI 0.72 to 0.88, respectively). After propensity matching, OS was improved in patients undergoing S (median 36.8 vs 20.8 months, log-rank p < 0.001). CONCLUSIONS: Advances in ST for non-small cell lung cancer may change the paradigm of eligibility for surgery. This study demonstrates that surgical resection of the primary tumor is associated with improved OS in selected patients with single-site oligometastatic disease.

ACR Lung-RADS v2022: Assessment Categories and Management Recommendations.

The American College of Radiology created the Lung CT Screening Reporting and Data System (Lung-RADS) in 2014 to standardize the reporting and management of screen-detected pulmonary nodules. Lung-RADS was updated to version 1.1 in 2019 and revised size thresholds for nonsolid nodules, added classification criteria for perifissural nodules, and allowed for short-interval follow-up of rapidly enlarging nodules that may be infectious in etiology. Lung-RADS v2022, released in November 2022, provides several updates including guidance on the classification and management of atypical pulmonary cysts, juxtapleural nodules, airway-centered nodules, and potentially infectious findings. This new release also provides clarification for determining nodule growth and introduces stepped management for nodules that are stable or decreasing in size. This article summarizes the current evidence and expert consensus supporting Lung-RADS v2022.

Minimally invasive surgery for clinical T4 non-small-cell lung cancer: national trends and outcomes.

OBJECTIVES: Recent randomized data support the perioperative benefits of minimally invasive surgery (MIS) for non-small-cell lung cancer (NSCLC). Its utility for cT4 tumours remains understudied. We, therefore, sought to analyse national trends and outcomes of minimally invasive resections for cT4 cancers. METHODS: Using the 2010-2019 National Cancer Database, we identified patients with cT4N0-1 NSCLC. Patients were stratified by surgical approach. Multivariable logistic analysis was used to identify factors associated with use of a minimally invasive approach. Groups were matched using propensity score analysis to evaluate perioperative and survival end points. RESULTS: The study identified 3715 patients, among whom 64.1% (n = 2381) underwent open resection and 35.9% (n = 1334) minimally invasive resection [robotic-assisted in 31.5% (n = 420); and video-assisted in 68.5% (n = 914)]. Increased MIS use was noted among patients with higher income [≥$40 227, odds ratio (OR) 1.24; 95% confidence interval (CI) 1.01-1.51] and those treated at academic hospitals (OR 1.25; 95% CI 1.07-1.45). Clinically node-positive patients (OR 0.68; 95% CI 0.55-0.83) and those who underwent neoadjuvant therapy (OR 0.78; 95% CI 0.65-0.93) were less likely to have minimally invasive resection. In matched groups, patients undergoing MIS had a shorter median length of stay (5 vs 6 days, P < 0.001) and no significant differences between 30-day readmissions or 30/90-day mortality. MIS did not compromise overall survival (log-rank P = 0.487). CONCLUSIONS: Nationally, the use of minimally invasive approaches for patients with cT4N0-1M0 NSCLC has increased substantially. In these patients, MIS is safe and does not compromise perioperative outcomes or survival.

Association of socioeconomic factors with the receipt of neoadjuvant therapy for patients with non-small cell lung cancer.

BACKGROUND: Neoadjuvant therapy (NT) will be increasingly used for patients with non-small cell lung cancer (NSCLC), particularly given the recent approval of neoadjuvant chemoimmunotherapy. Several barriers may prevent the uptake of NT and should be identified and addressed. We queried the National Cancer Database (NCDB) to determine predictors of the use of NT. METHODS: Using the NCDB (2006-2019), we identified 80,707 patients who underwent surgery for clinical stage II and III NSCLC. Sociodemographic and clinical factors were reviewed, and univariable and multivariable analyses were performed to identify associations with the uptake of NT. In propensity score-matched groups, survival was determined using the Kaplan-Meier method. RESULTS: Among 80,707 eligible patients, 17,262 (21.4%) received NT. Clinical stage and node positivity were associated with receipt of NT. On multivariable analysis, factors associated with lower rates of NT included black race (odds ratio [OR], 0.78; 95% confidence interval [CI], 0.67-0.90), Charlson Comorbidity Index ≥2 (OR, 0.75; 95% CI, 0.67-0.85), Medicaid/Medicare insurance (OR, 0.82; 95% CI, 0.75-0.90), lower income level (OR, 0.79; 95% CI, 0.71-0.87), and treatment at a community center (OR, 0.81; 95% CI, 0.67-0.96). In an exploratory analysis, those patients who received NT had longer 5-year overall survival compared with those who did not (48.3% vs 46.0%; P < .001). CONCLUSIONS: Rates of NT are relatively low for patients with clinical stage II/III NSCLC treated prior to recent chemoimmunotherapy trials. Socioeconomic barriers to the uptake of NT include race, insurance status, income, and area of residence. As NT becomes more widely offered, accessibility for vulnerable populations must be assured.

The Effect of Neoadjuvant Therapy on Esophagectomy for cT2N0M0 Esophageal Adenocarcinoma.

BACKGROUND: For cT2N0M0 esophageal adenocarcinomas, the effects of neoadjuvant chemoradiotherapy (NT) on surgical outcomes and the oncological benefits to the patients are debatable. In this study, we investigated the optimal management for cT2N0M0 adenocarcinoma (1) assessing the perioperative impact of NT on esophagectomy and (2) evaluating the oncologic effect of NT in a homogeneous group of patients with clinical stage IIA. We hypothesized that NT does not negatively affect perioperative outcomes and provides an oncologic benefit to selected patients with cT2N0M0 disease. METHODS: The National Cancer Database was queried (2010-2019) for patients with cT2N0M0 esophageal adenocarcinoma undergoing esophagectomy. After propensity-matching to adjust for differences in patient and tumor characteristics, we compared postoperative outcomes (logistic regression) and survival (Kaplan-Meier and Cox regression) among those who underwent NT vs upfront surgery (S). RESULTS: This study included 3413 patients, of whom 2359 (69%) received NT, and 1054 (31%) S. In contrast to those who underwent S, in the matched cohort, patients treated with NT had comparable conversion rates (8% vs11.1%, p = 0.06), length of stay (9 vs 10 days, p = 0.078), unplanned readmission (5.4% vs 8.8%, p = 0.109), and 30- (3.9% vs 3.7%, p = 0.90) and 90-day mortality (5.7% vs 4.7%, p = 0.599). In addition, NT associated with improved survival in patients with cT2N0M0 tumors > 5 cm (HR 0.30, 95% CI 0.17-0.36). CONCLUSIONS: NT does not appear to increase technical complexity or to adversely affect postoperative outcomes after esophagectomy. Furthermore, minimally invasive esophagectomy is feasible following NT, with comparable conversion rates to those who had upfront surgery. Lastly, NT was selectively associated with improved survival in patients with cT2N0M0 esophageal cancer.

Sublobar resection is associated with less lymph nodes examined and lower delivery of adjuvant therapy in patients with 1.5- to 2.0-cm clinical IA2 non-small-cell lung cancer: a retrospective cohort study.

OBJECTIVES: CALGB140503, in which nodal sampling was mandated, reported non-inferior disease-free survival for patients undergoing sublobar resection (SLR) compared to lobectomy (L). Outside of trial settings, the adequacy of lymphadenectomy during SLR has been questioned. We sought to evaluate whether SLR is associated with suboptimal lymphadenectomy, differences in pathologic upstaging and survival in patients with 1.5- to 2.0-cm tumours using real-world data. MATERIALS AND METHODS: Using the National Cancer Database(2018-2019), we evaluated patients with 1.5- to 2.0-cm non-small-cell lung cancer who underwent resection (sublobar versus lobectomy). We studied factors associated with nodal upstaging (logistic regression) and survival (Cox regression and Kaplan-Meier method) after propensity matching to adjust for differences among groups. RESULTS: Among 3196 patients included, SLR was performed in 839 (26.3%) (of which 588 were wedge resections) and L was performed in 2357 (73.7%) patients. More patients undergoing SLR (21.7%) compared to L (2.1%) had no lymph nodes sampled (P < 0.001). Those undergoing SLR had fewer total lymph nodes examined (4 vs 11, P < 0.001) and were less likely to have pathologic nodal metastases (4.7% vs 9%, P < 0.001) compared to L. Multivariable analysis identified L [adjusted odds ratio (aOR) 2.21, 95% confidence interval, 1.47-3.35] to be independently associated with pathologic N+ disease. Overall survival was not associated with the type of procedure but was significantly decreased in those with N+ disease. CONCLUSIONS: Despite comparable overall survival to L, SLR is associated with suboptimal lymphadenectomy in patients with 1.5-2.0 cm non-small-cell lung cancer. Surgeons should be careful to perform adequate lymphadenectomy when performing SLR to mitigate nodal under-staging and to identify appropriate patients for systemic therapy.
