Comparative effectiveness of perioperative physical activity in older adults with lung cancer and their family caregivers: design of a multicenter pragmatic randomized trial.

BACKGROUND: With a median age at diagnosis of 70, lung cancer remains a significant public health challenge for older Americans. Surgery is a key component in treating most patients with non-metastatic lung cancer. These patients experience postoperative pain, fatigue, loss of respiratory capacity, and decreased physical function. Data on quality of life (QOL) in older adults undergoing lung cancer surgery is limited, and few interventions are designed to target the needs of older adults and their family caregivers (FCGs). The primary aim of this comparative effectiveness trial is to determine whether telephone-based physical activity coaching before and after surgery will be more beneficial than physical activity self-monitoring alone for older adults and their FCGs. METHODS: In this multicenter comparative effectiveness trial, 382 older adults (≥ 65 years) with lung cancer and their FCGs will be recruited before surgery and randomized to either telephone-based physical activity coaching or physical activity self-monitoring alone. Participants allocated to the telephone-based coaching comparator will receive five telephone sessions with coaches (1 pre and 4 post surgery), an intervention resource manual, and a wristband pedometer. Participants in the self-monitoring only arm will receive American Society of Clinical Oncology (ASCO) physical activity information and wristband pedometers. All participants will be assessed at before surgery (baseline), at discharge, and at days 30, 60, and 180 post-discharge. The primary endpoint is the 6-minute walk test (6MWT) at 30 days post-discharge. Geriatric assessment, lower extremity function, self-reported physical function, self-efficacy, and QOL will also be assessed. DISCUSSION: The trial will determine whether this telephone-based physical activity coaching approach can enhance postoperative functional capacity and QOL outcomes for older adults with lung cancer and their FCGs. Trial results will provide critical findings to inform models of postoperative care for older adults with cancer and their FCGs. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT06196008.

ACR Appropriateness Criteria® Incidentally Detected Indeterminate Pulmonary Nodule.

Incidental pulmonary nodules are common. Although the majority are benign, most are indeterminate for malignancy when first encountered making their management challenging. CT remains the primary imaging modality to first characterize and follow-up incidental lung nodules. This document reviews available literature on various imaging modalities and summarizes management of indeterminate pulmonary nodules detected incidentally. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

Lung Cancer Screening in Clinical Practice: A 5-Year Review of Frequency and Predictors of Lung Cancer in the Screened Population.

PURPOSE: The aims of this study were to evaluate (1) frequency, type, and lung cancer stage in a clinical lung cancer screening (LCS) population and (2) the association between patient characteristics and Lung CT Screening Reporting & Data System (Lung-RADS®) with lung cancer diagnosis. METHODS: This retrospective study enrolled individuals undergoing LCS between January 1, 2015, and June 30, 2020. Individuals' sociodemographic characteristics, Lung-RADS scores, pathology-proven lung cancers, and tumor characteristics were determined via electronic health record and the health system's tumor registry. Associations between the outcome of lung cancer diagnosis within 1 year after LCS and covariates of sociodemographic characteristics and Lung-RADS score were determined using logistic regression. RESULTS: Of 3,326 individuals undergoing 5,150 LCS examinations, 102 (3.1%) were diagnosed with lung cancer within 1 year of LCS; most of these cancers were screen detected (97 of 102 [95.1%]). Over the study period, there were 118 total LCS-detected cancers in 113 individuals (3.4%). Most LCS-detected cancers were adenocarcinomas (62 of 118 [52%]), 55.9% (65 of 118) were stage I, and 16.1% (19 of 118) were stage IV. The sensitivity, specificity, positive predictive value, and negative predictive value of Lung-RADS in diagnosing lung cancer within 1 year of LCS were 93.1%, 83.8%, 10.6%, and 99.8%, respectively. On multivariable analysis controlling for sociodemographic characteristics, only Lung-RADS score was associated with lung cancer (odds ratio for a one-unit increase in Lung-RADS score, 4.68; 95% confidence interval, 3.87-5.78). CONCLUSIONS: The frequency of LCS-detected lung cancer and stage IV cancers was higher than reported in the National Lung Screening Trial. Although Lung-RADS was a significant predictor of lung cancer, the positive predictive value of Lung-RADS is relatively low, implying opportunity for improved nodule classification.

Development of a multi-feature-combined model: proof-of-concept with application to local failure prediction of post-SBRT or surgery early-stage NSCLC patients.

Objective: To develop a Multi-Feature-Combined (MFC) model for proof-of-concept in predicting local failure (LR) in NSCLC patients after surgery or SBRT using pre-treatment CT images. This MFC model combines handcrafted radiomic features, deep radiomic features, and patient demographic information in an integrated machine learning workflow. Methods: The MFC model comprised three key steps. (1) Extraction of 92 handcrafted radiomic features from the GTV segmented on pre-treatment CT images. (2) Extraction of 512 deep radiomic features from pre-trained U-Net encoder. (3) The extracted handcrafted radiomic features, deep radiomic features, along with 4 patient demographic information (i.e., gender, age, tumor volume, and Charlson comorbidity index), were concatenated as a multi-dimensional input to the classifiers for LR prediction. Two NSCLC patient cohorts from our institution were investigated: (1) the surgery cohort includes 83 patients with segmentectomy or wedge resection (7 LR), and (2) the SBRT cohort includes 84 patients with lung SBRT (9 LR). The MFC model was developed and evaluated independently for both cohorts, and was subsequently compared against the prediction models based on only handcrafted radiomic features (R models), patient demographic information (PI models), and deep learning modeling (DL models). ROC with AUC was adopted to evaluate model performance with leave-one-out cross-validation (LOOCV) and 100-fold Monte Carlo random validation (MCRV). The t-test was performed to identify the statistically significant differences. Results: In LOOCV, the AUC range (surgery/SBRT) of the MFC model was 0.858-0.895/0.868-0.913, which was higher than the three other models: 0.356-0.480/0.322-0.650 for PI models, 0.559-0.618/0.639-0.682 for R models, and 0.809/0.843 for DL models. In 100-fold MCRV, the MFC model again showed the highest AUC results (surgery/SBRT): 0.742-0.825/0.888-0.920, which were significantly higher than PI models: 0.464-0.564/0.538-0.628, R models: 0.557-0.652/0.551-0.732, and DL models: 0.702/0.791. Conclusion: We successfully developed an MFC model that combines feature information from multiple sources for proof-of-concept prediction of LR in patients with surgical and SBRT early-stage NSCLC. Initial results suggested that incorporating pre-treatment patient information from multiple sources improves the ability to predict the risk of local failure.

Historical Perspective on Lung Cancer Screening.

Lung cancer represents a large burden on society with a staggering incidence and mortality rate that has steadily increased until recently. The impetus to design an effective screening program for the deadliest cancer in the United States and worldwide began in 1950. It has taken more than 50 years of numerous clinical trials and continued persistence to arrive at the development of modern-day screening program. As the program continues to grow, it is important for clinicians to understand its evolution, track outcomes, and continually assess the impact and bias of screening on the medical, social, and economic systems.

ACR Appropriateness Criteria® Lung Cancer Screening: 2022 Update.

Lung cancer remains the leading cause of cancer-related mortality for men and women in the United States. Screening for lung cancer with annual low-dose CT is saving lives, and the continued implementation of lung screening can save many more. In 2015, the CMS began covering annual lung screening for those who qualified based on the original United States Preventive Services Task Force (USPSTF) lung screening criteria, which included patients 55 to 77 year of age with a 30 pack-year history of smoking, who were either currently using tobacco or who had smoked within the previous 15 years. In 2021, the USPSTF issued new screening guidelines, decreasing the age of eligibility to 80 years of age and pack-years to 20. Lung screening remains controversial for those who do not meet the updated USPSTF criteria, but who have additional risk factors for the development of lung cancer. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

The Thoracic Surgery Medical Student Association: Understanding the needs of medical students pursuing cardiothoracic surgery in the United States.

OBJECTIVE: Founded in 2020, the Thoracic Surgery Medical Student Association is the first national organization dedicated to supporting medical students interested in pursuing cardiothoracic surgery. Our inaugural survey aimed to describe their basic characteristics and needs. METHODS: An Institutional Review Board-approved, nonincentivized, anonymous electronic survey was distributed to any medical students enrolled in Liaison Committee on Medical Education-accredited medical schools through social media such as Twitter, national organizations (Association of Women Surgeons, Thoracic Surgery Resident Association), and medical school cardiothoracic surgery interest groups. Their basic characteristics, attitudes, and preferences regarding cardiothoracic surgery were recorded. RESULTS: Of the 167 students from 117 unique schools who completed the survey, 53% identified as White and 57% identified as female. Stages of training were well distributed: 16% first-year medical students, 33% second-year medical students, 16% third-year medical students, 21% fourth-year medical students, and 14% dual degree/research students. Most participants (57%) did not have (32%) or were not aware of having (25%) a thoracic surgery training program at their home institution. The majority (72%) of students reported not having a cardiothoracic surgery interest group at their home institution. The most desired areas of cardiothoracic were networking (31%) and mentorship (28%). CONCLUSIONS: There is a significant need to directly engage medical students who are interested in cardiothoracic surgery considering limited exposure at home institutions through a lack of cardiothoracic surgery interest groups and cardiothoracic residency programs. The Thoracic Surgery Medical Student Association is poised to address these areas with directed networking by connecting cardiothoracic surgery faculty and residents from other institutions with medical students interested in pursuing cardiothoracic surgery.

Surgical Evaluation in Patients Undergoing Radiation Therapy for Early-Stage Lung Cancer.

BACKGROUND: Stereotactic body radiation therapy (SBRT) is used to treat stage I non-small cell lung cancer (NSCLC) in nonsurgical candidates, although guidelines specify that inoperability be determined in multidisciplinary fashion. We characterized NSCLC patients treated with SBRT undergoing thoracic surgical evaluation (TSUe) and quantified TSUe's impact on time to treatment, receipt of diagnostic staging procedures, and health care costs. METHODS: Adults with newly diagnosed NSCLC undergoing SBRT were identified in the MarketScan all-payer claims database (2014-2018). TSUe was defined as an outpatient encounter with a thoracic surgeon or multispecialty group. Time to treatment and total costs in the 6 months preceding treatment were examined using multivariable regression by receipt of TSUe, adjusting for demographic and clinical factors. RESULTS: Of 1894 patients, 36.3% (n = 687) underwent TSUe. Compared with patients without TSUe, these patients were younger (mean age, 73.6 vs 76.3 years) and more likely to undergo invasive biopsy/staging procedures (90% vs 82%) or pulmonary function testing (80.6% vs 69.5%). Patients undergoing TSUe had a median time to treatment of 64 days (interquartile range, 43-98 days), compared with 44 days (interquartile range, 29-70 days) for no TSUe. Adjusted time to treatment was 43% longer (incident rate ratio, 1.43; 95% CI, 1.32-1.54; P < .001) with TSUe. Patients undergoing TSUe also incurred 30% higher costs (adjusted cost ratio, 1.30; 95% CI, 1.20-1.41; P < .001). CONCLUSIONS: Among patients with early-stage NSCLC undergoing SBRT as primary treatment, a minority are evaluated by a thoracic surgeon. Because they have a longer time to treatment, more invasive diagnostic procedures, and higher costs, this represents a targetable gap to make workup protocols more efficient.

The Effect of Center Esophagectomy Volume on Outcomes in Clinical Stage I to III Esophageal Cancer.

OBJECTIVE: To determine the threshold annualized esophagectomy volume that is associated with improved survival, oncologic resection, and postoperative outcomes. BACKGROUND: Esophagectomy at high-volume centers is associated with improved outcomes; however, the definition of high-volume remains debated. METHODS: The 2004 to 2016 National Cancer Database was queried for patients with clinical stage I to III esophageal cancer undergoing esophagectomy. Center esophagectomy volume was modeled as a continuous variable using restricted cubic splines. Maximally selected ranks were used to identify an inflection point of center volume and survival. Survival was compared using multivariable Cox proportional hazards methods. Multivariable logistic regression was used to examine secondary outcomes. RESULTS: Overall, 13,493 patients met study criteria. Median center esophagectomy volume was 8.2 (interquartile range: 3.2-17.2) cases per year. On restricted cubic splines, inflection points were identified at 9 and 30 cases per year. A multivariable Cox model was constructed modeling annualized center surgical volume as a continuous variable using 3 linear splines and inflection points at 9 and 30 cases per year. On multivariable analysis, increasing center volume up to 9 cases per year was associated with a substantial survival benefit (hazard ratio: 0.97, 95% confidence interval, 0.95-0.98, P ≤0.001). On multivariable logistic regression, factors associated with undergoing surgery at a high-volume center (>9 cases per year) included private insurance, care at an academic center, completion of high school education, and greater travel distance. CONCLUSIONS: This National Cancer Database study utilizing multivariable analysis and restricted cubic splines suggests the threshold definition of a high-volume esophagectomy center as one that performs at least 10 operations a year.

Multi-institutional Care in Clinical Stage II and III Esophageal Cancer.

BACKGROUND: Management of clinical stage II or III esophageal cancer requires multidisciplinary care. Multi-institutional care has been associated with worse survival in other malignant diseases. This study aimed to determine the impact of multi-institutional care on survival in patients with stage II or III esophageal cancer. METHODS: The 2004 to 2016 National Cancer Database was queried for patients with clinical stage II or III esophageal cancer who received neoadjuvant chemotherapy with or without radiation therapy followed by surgical resection. Patients were stratified into 2 groups: multi-institutional or single-institution care. Survival between groups was compared using Kaplan-Meier and multivariable Cox proportional hazards methods. Multivariable logistic regression was performed to identify factors associated with multi-institutional care. RESULTS: Overall, 11 399 patients met study criteria: 6569 (57.6%) received multi-institutional care and 4,830 (42.4%) received care at a single institution. In a multivariable analysis, factors associated with multi-institutional care were later year of diagnosis, greater distance from treating facility, residence in an urban or rural setting (vs metro), and residence in states without Medicaid expansion. Care at a single institution was associated with Black race, lack of insurance, and treatment at higher-volume or academic centers. Despite these differences, patients who received multi-institutional care had survival comparable to that in patients who received care at a single institution (HR, 0.97; 95% CI, 0.92-1.03; P = .30). CONCLUSIONS: In this National Cancer Database analysis, multi-institutional care was not associated with inferior overall survival. As complex cancer care becomes more regionalized, patients may consider receiving part of their cancer care closer to home, whereas traveling to surgical centers of excellence should be encouraged.

The Impact of Adjuvant Hemithoracic Radiation on Outcomes in Patients With Stage I-III Malignant Pleural Mesothelioma: A Dual Registry Analysis.

BACKGROUND: The outcomes associated with receipt of adjuvant radiation in patients after surgery for MPM are poorly understood. OBJECTIVE: The objective of this study was to use 2 registries to compare the outcomes of patients receiving adjuvant radiation or no radiation after definitive surgery for pathologic stage I-III MPM. METHODS: Patients with resected pathologic stage I-III MPM were identified from the Duke University registry (1996-2016) and National Cancer Database (NCDB) (2004-2015). The primary outcome was overall survival. Propensity score-matched and landmark subgroup analyses were performed. RESULTS: A total of 212 institutional and 1615 NCDB patients met criteria. In both cohorts, patients who underwent radiation were more likely to have margin-negative resection and more advanced pathologic stage. At a landmark time of 4.4 and 4.7 months from surgery, Duke [hazard ratio (HR) 1.14; 95% confidence interval (CI) 0.62-2.11] and NCDB patients (HR 0.97; 95% CI 0.81-1.17) who received adjuvant radiation did not experience improved survival compared to those who did not receive radiation in multivariable analysis. Duke patients who received radiation had similar incidence of recurrence and time to both overall recurrence and ipsilateral recurrence (HR 0.87; 95% CI 0.43-1.77) compared to those who did not. Duke patients experienced 100 grade 1/2, 21 grade 3/4, and one grade 5 toxicity events during radiation. CONCLUSIONS: In this dual registry analysis of patients with resected stage I-III MPM, the receipt of adjuvant hemithoracic radiation was not associated with improved survival compared to no radiation.

NCCN Guidelines® Insights: Lung Cancer Screening, Version 1.2022.

The NCCN Guidelines for Lung Cancer Screening recommend criteria for selecting individuals for screening and provide recommendations for evaluation and follow-up of lung nodules found during initial and subsequent screening. These NCCN Guidelines Insights focus on recent updates to the NCCN Guidelines for Lung Cancer Screening.

Predictors of Early Onset Glaucoma.

Purpose/Relevance: To determine the influence of hypertension (HTN), type 2 diabetes (DM2), migraine, and obstructive sleep apnea (OSA) on the onset of primary open-angle glaucoma (POAG) to enhance predictive accuracy. Methods: In this cross-sectional study, data for 389 eligible patients with POAG were collected through medical records review and phone surveys. All data were assessed collectively using stepwise multiple regression analysis to determine the relative contribution to age at POAG diagnosis. We used the following groups, based on age at diagnosis, HTN for patients with or without DM2 (model 1), HTN for patients with DM2 (model 2), DM2 for patients with or without HTN (model 3), and DM2 for patients with HTN (model 4). Results: In model 1, age at HTN diagnosis was associated with age at POAG diagnosis (ß = 0.14; 95% CI, 0.01-0.26, p = 0.04). In model 2, age at HTN diagnosis was not associated with age at POAG diagnosis (p > 0.05). In model 3, age at DM2 diagnosis was associated with age at POAG diagnosis (ß = 0.37; 95% CI 0.16-0.58, p = 0.001). In model 4, age at DM2 diagnosis was associated with age at POAG diagnosis (ß = 0.40; 95% CI 0.00-0.15, p = 0.003). Asian race/ethnicity was associated with early onset of POAG in model 3 (ß = -6.44; 95% CI -12.34-0.54, p = 0.033). OSA and migraine did not influence the onset of POAG. Conclusion: Our study found that the diagnosis of DM2 and HTN at an earlier age is associated with the early onset of POAG.

Social Disparities in Lung Cancer Risk and Screening.

Significant disparities exist in lung cancer incidence and screening. Geographic, racial, gender, and socioeconomic disparities affect lung cancer incidence. As the leading cause of lung cancer, smoking varies among different racioethnic groups, genders, and socioeconomic statuses. In addition, environmental pollutants, such as radon, industrial toxins, and air pollution, are significant risk factors for lung cancer development that is disproportionately seen in working-class communities, as well as underserved and disabled populations. Lung cancer incidence depends on diagnosis. Literature examining lung cancer incidence and screening disparities have its limitations, as most studies are methodologically limited and do not adjust for important risk factors.

Comparison of Forceps, Cryoprobe, and Thoracoscopic Lung Biopsy for the Diagnosis of Interstitial Lung Disease - The CHILL Study.

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.

The Impact of Adjuvant Therapy on Survival After Esophagectomy for Node-negative Esophageal Adenocarcinoma.

OBJECTIVE: Determine whether adjuvant chemotherapy is associated with a survival benefit in high risk T2-4a, pathologically node-negative distal esophageal adenocarcinoma. SUMMARY OF BACKGROUND DATA: There is minimal literature to substantiate the NCCN guidelines recommending adjuvant therapy for patients with distal esophageal adenocarcinoma and no pathologic evidence of nodal disease. METHODS: The National Cancer Database was used to identify adult patients with pT2-4aN0M0 esophageal adenocarcinoma who underwent definitive surgery (2004-2015) and had characteristics considered high risk by the NCCN. Patients were stratified by receipt of adjuvant chemotherapy with or without radiation. The primary outcome was overall survival, which was evaluated using Kaplan-Meier and multivariable Cox Proportional Hazards models. A 1:1 propensity score-matched analysis was also performed to compare survival between the groups. RESULTS: Four hundred three patients met study criteria: 313 (78%) without adjuvant therapy and 90 who received adjuvant chemotherapy with or without radiation (22%). In both unadjusted and multivariable analysis, adjuvant chemotherapy with or without radiation was not associated with a significant survival benefit compared to no adjuvant therapy. In a subgroup analysis of 335 patients without high risk features by NCCN criteria, adjuvant chemotherapy was not independently associated with a survival benefit. CONCLUSION: In this analysis, adjuvant chemotherapy with or without radiation was not associated with a significant survival benefit in completely resected, pathologically node-negative distal esophageal adenocarcinoma, independent of presence of high risk characteristics. The risks and benefits of adjuvant therapy should be weighed before offering it to patients with completely resected pT2-4aN0M0 esophageal adenocarcinoma.

Consensus for Thoracoscopic Lower Lobectomy: Essential Components and Targets for Simulation.

BACKGROUND: Despite demonstration of its clear benefits relative to open approaches, a video-assisted thoracic surgery technique for pulmonary lobectomy has not been universally adopted. This study aims to overcome potential barriers by establishing the essential components of the operation and determining which steps are most useful for simulation training. METHODS: After randomly selecting experienced thoracic surgeons to participate, an initial list of components to a lower lobectomy was distributed. Feedback was provided by the participants, and modifications were made based on anonymous responses in a Delphi process. Components were declared essential once at least 80% of participants came to an agreement. The steps were then rated based on cognitive and technical difficulty followed by listing the components most appropriate for simulation. RESULTS: After 3 rounds of voting 18 components were identified as essential to performance of a video-assisted thoracic surgery for lower lobectomy. The components deemed the most difficult were isolation and division of the basilar and superior segmental branches of the pulmonary artery, isolation and division of the lower lobe bronchus, and dissection of lymphovascular tissue to expose the target bronchus. The steps determined to be most amenable for simulation were isolation and division of the branches of the pulmonary artery, the lower lobe bronchus, and the inferior pulmonary vein. CONCLUSIONS: Using a Delphi process a list of essential components for a video-assisted thoracic surgery for lower lobectomy was established. Furthermore 3 components were identified as most appropriate for simulation-based training, providing insights for future simulation development.

Impact of Time to Endoscopic Resection on Outcomes for Stage I Esophageal Adenocarcinoma.

BACKGROUND: Endoscopic resection (ER) is the preferred treatment for superficial esophageal cancer; however, a safe time frame for performing ER has not been established. This study evaluated the period in which ER can be performed for patients with stage I esophageal adenocarcinoma without compromising outcomes. METHODS: The 2004-2015 National Cancer Database was used to identify patients with cT1 N0 M0 esophageal adenocarcinoma who underwent upfront ER. The primary outcome was overall survival, which was evaluated using Kaplan-Meier and multivariable Cox proportional hazards methods. The secondary outcome was rate of margin-positive resection, which was evaluated using a multivariable logistic regression. RESULTS: A total of 983 patients met study criteria. The median time from diagnosis to ER was 34 days (interquartile range, 5-70 days). Patients in the highest quartile of time to ER were more likely to be treated at a high-volume center and at a center different from that of diagnosis compared with those in the lowest quartile. Increasing time to ER was not independently associated with survival (adjusted hazard ratio per 10 days, 1.02; 95% confidence interval, 0.98-1.05; P = .32) or margin-positive resection (odds ratio per 10 days 1.01; 95% confidence interval, 0.96-1.06; P = .60). CONCLUSIONS: In this National Cancer Database analysis, increasing time to endoscopic resection, up to 180 days from diagnosis, was not associated with worsened survival or increased odds of margin-positive resection in patients with cT1 N0 M0 esophageal adenocarcinoma. Given these findings, patients may be afforded time to be seen in specialty centers without risk of tumor progression.

2020 Women in Thoracic Surgery Update on the Status of Women in Cardiothoracic Surgery.

BACKGROUND: Women in Thoracic Surgery (WTS) has previously reported on the status of women in cardiothoracic (CT) surgery. We sought to provide a 10-year update on women in CT surgery. METHODS: An anonymous research electronic data capture survey link was emailed to female diplomats of the American Board of Thoracic Surgery. Survey questions queried respondents regarding demographics, training, accolades, practice details, and career satisfaction. The survey link was open for 30 days. Results were compared with The Society of Thoracic Surgeons 2019 workforce survey. Descriptive analyses were performed using frequency and proportions. Comparisons were performed using Student's t tests, Fisher's exact tests, and χ2 tests. RESULTS: Of 354 female diplomats, 309 were contacted and 176 (57%) responded. The majority of respondents were aged 36 to 50 years (59%), white (67.4%), and had graduated from traditional-track programs (91.4%). Most respondents reported practicing in an urban (64%) and academic setting (73.1%). 36.4% and 23.9% reported a general thoracic and adult cardiac practice (22.7% mixed practice, 9.6% congenital). Fifty percent of respondents reported salaries between $400,000 and $700,000 annually; 37.7% reported salaries less than 90% of their male colleagues; 21.6% of respondents in academia are full professor; 53.4% reported having a leadership role. Whereas 74.1% would pursue a career in CT surgery again, only 27.3% agreed that CT surgery is a healthy and positive environment for women. CONCLUSIONS: The number of women in CT surgery has steadily increased. Although women are rising in academic rank and into leadership positions, salary disparities and the CT surgery work environment remain important issues in achieving a diverse work force.
