RESUMO
OBJECTIVES: The aim of this study was to identify drivers of time from diagnosis to treatment (TTT) of surgically resected early stage non-small cell lung cancer (NSCLC) and determine the effect of TTT on post-resection survival. SUMMARY BACKGROUND DATA: Large database studies that lack relevant comorbidity data have identified longer TTT asa driver of worse overall survival. METHODS: From January 1, 2014 to April 1, 2018, 599 patients underwent lung resection for clinical stage I and II NSCLC. Random forest classification, regression, and survival were used to estimate likelihood of TTT = 0 (tissue diagnosis obtained at surgery), >0 (diagnosis obtained pre-resection), and effect of TTT on all-cause mortality. RESULTS: Patients with TTT > 0 (n = 413) had median TTT of 42 days (25-75 th percentile: 27-59 days). Patients with TTT = 0 (n = 186) had smaller tumors and higher percent predicted forced expiratory volume in 1 second (FEV 1 %). Patients with history of stroke, oncology consultation, invasive mediastinal staging, low and high extremes of FEV 1 % had longer TTT. Higher clinical stage, lack of preoperative stress test, anemia, older age, lower FEV1% and diffusion lung capacity, larger tumor size, and longer TTT were the most important predictors of all-cause mortality. One- and 5-year overall survival decreased when TTT was >50 days. CONCLUSIONS: Preoperative physiologic workup and multidisciplinary evaluation were the predominant drivers of longer TTT. Patients with TTT = 0have more favorable presentation and should be considered in TTT analyses for early stage lung cancer populations. The time needed to clinically stage and optimize patients for resection is not deleterious to overall survival until resection is performed after 50 days from diagnosis.

OBJECTIVE: We hypothesized that, on average, patients do not benefit from additional adjuvant therapy after neoadjuvant therapy for locally advanced esophageal cancer, although subsets of patients might. Therefore, we sought to identify profiles of patients predicted to receive the most survival benefit or greatest detriment from adding adjuvant therapy. BACKGROUND: Although neoadjuvant therapy has become the treatment of choice for locally advanced esophageal cancer, the value of adding adjuvant therapy is unknown. METHODS: From 1970 to 2014, 22,123 patients were treated for esophageal cancer at 33 centers on 6 continents (Worldwide Esophageal Cancer Collaboration), of whom 7731 with adenocarcinoma or squamous cell carcinoma received neoadjuvant therapy; 1348 received additional adjuvant therapy. Random forests for survival and virtual-twin analyses were performed for all-cause mortality. RESULTS: Patients received a small survival benefit from adjuvant therapy (3.2±10 months over the subsequent 10 years for adenocarcinoma, 1.8±11 for squamous cell carcinoma). Consistent benefit occurred in ypT3-4 patients without nodal involvement and those with ypN2-3 disease. The small subset of patients receiving most benefit had high nodal burden, ypT4, and positive margins. Patients with ypT1-2N0 cancers had either no benefit or a detriment in survival. CONCLUSIONS: Adjuvant therapy after neoadjuvant therapy has value primarily for patients with more advanced esophageal cancer. Because the benefit is often small, patients considering adjuvant therapy should be counseled on benefits versus morbidity. In addition, given that the overall benefit was meaningful in a small number of patients, emerging modalities such as immunotherapy may hold more promise in the adjuvant setting.

BACKGROUND: Esophageal morphology in achalasia is thought to affect outcomes, with "end-stage" sigmoidal morphology faring poorly; however, evaluation of morphology's role in outcomes has been limited by lack of objective characterization. Hence, the goals of this study were twofold: characterize the variability of timed barium esophagram (TBE) interpretation and evaluate an objective classification of TBE tortuosity: length-to-height ratio (LHR). We hypothesized that the esophagus must elongate to become sigmoidal such that sigmoidal morphology would demonstrate a larger LHR. METHODS: Ninety pre-operative TBEs were selected from an institutional database. Esophageal morphology was categorized as straight, intermediate, or sigmoidal. Esophageal length was measured by a mid-lumen line from the aortic knob to the esophagogastric junction on TBE; height was measured vertically from the aortic knob to the level of the esophagogastric junction. The length divided by the height generated the LHR. Descriptive statistics and frequency of expert agreement were calculated. Median LHR was compared between consensus morphologies. A receiver operating characteristic (ROC) determined the optimal LHR for sigmoidal vs non-sigmoidal characterization. RESULTS: From a total of 90 pre-operative TBEs, expert consensus morphology was reached in 56 (62.2%) cases. Pairs of experts agreed on morphology in 62-74% of TBEs, with all three experts agreeing on 46.7-48.9% of cases. Median LHR between expert consensus morphologies was 1.03, 1.09, and 1.24 for straight, intermediate, and sigmoidal morphologies, respectively (p < 0.001). ROC demonstrated that an LHR cutoff of 1.13 was 100% sensitive and 95% specific (AUC 0.99) for ruling out sigmoidal morphology. CONCLUSION: These findings confirm our anecdotal experience that subjective morphology interpretation is variable, even between experts at a high-volume center. LHR provides an objective method for classification, allowing us to overcome the limitations of inter-observer variability, thus paving the way for future study of the role of morphology in achalasia outcomes.

OBJECTIVE: The aim of this study was to assess the effect on survival of extent of lymphadenectomy during esophagectomy for patients undergoing multimodality (neoadjuvant) therapy for adenocarcinoma of the esophagus and esophagogastric junction using Worldwide Esophageal Cancer Collaboration data. SUMMARY BACKGROUND DATA: Previous worldwide data demonstrated that optimum lymphadenectomy during esophagectomy alone for esophageal cancer provides accurate staging and maximum survival. However, for patients undergoing neoadjuvant therapy for locally advanced adenocarcinoma, its value is unclear, leading to wide practice variability. METHODS: A total of 3859 patients with adenocarcinoma of the esophagus or esophagogastric junction received neoadjuvant therapy. The endpoint was all-cause mortality, reported as gain or loss of lifetime within 10 years. Lifetime predicted for each regional lymph node resected used quantile survival random forest methodology. RESULTS: Across all post-neoadjuvant ypTNM cancer categories, some degree of lymphadenectomy was associated with longer lifetime, but in a nonlinear fashion. For patients with ypN0 cancers, there was a modest gain in lifetime up to 25 lymph nodes resected and an incremental loss in lifetime as >25 were resected. For patients with ypN+ cancers, there was a robust gain in lifetime up to 30 lymph nodes resected and then an incremental loss in lifetime. CONCLUSIONS: Worldwide data for adenocarcinoma of the esophagus and esophagogastric junction demonstrate that lymphadenectomy during esophagectomy is a valuable component of neoadjuvant therapy. Survival is maximized when an optimum range of nodes is resected.

OBJECTIVES: The aim of this study was to determine differences in esophageal perforation populations undergoing different advanced interventions for perforated esophagus and identify predictors of treatment outcomes. SUMMARY BACKGROUND DATA: Contained esophageal perforation can often be managed expectantly, but uncontained perforation is uniformly fatal without invasive intervention. Treatment options for the latter range from simple endoscopic control through advanced intervention. Clinical presentation varies greatly and directs which intervention is most appropriate. METHODS: From 1996 to 2017, 335 patients were treated for esophageal perforation, and 166 for advanced interventions: 74 primary repair with tissue flap (repair), 26 esophagectomy and gastric pull-up (resection), and 66 esophagectomy and immediate diversion with planned delayed reconstruction (resection-diversion). Patient characteristics, clinical presentation, operative outcomes, and survival were abstracted. Pittsburgh Severity Scores (PSS) were retrospectively calculated. Random survival forest analysis was performed for 90-day mortality and competing risks for reconstruction after resection-diversion. RESULTS: Repair and resection patients had lower PSS than resection-diversion patients (3 vs 3 vs 6, respectively). Ninety-day mortality for repair, resection, and resection-diversion was 11% vs 7.7% vs 23%, and 5-year survival was 71% vs 63% vs 47%. Risk of death after resection-diversion was highest within 1 year, but 52% of patients had reconstruction of the upper alimentary tract within 2 years. CONCLUSIONS: Several advanced interventions exist for critically ill patients with uncontained esophageal perforation. Repair and organ preservation are always preferred; however, patients at extremes of illness might best be treated with resection-diversion, with the understanding that the competing risk of death may preclude eventual reconstruction.

OBJECTIVE: Assess the efficacy of adding liposomal bupivacaine (LB) to bupivacaine-containing intercostal nerve blocks (ICNBs) to improve analgesia and decrease opioid consumption and hospital length of stay compared with bupivacaine-only ICNBs. DESIGN: This retrospective, observational investigation compared pain intensity scores and cumulative opioid consumption within the first 72 postoperative hours in patients who received ICNBs with bupivacaine plus LB (LB group) versus bupivacaine only (control group) after minimally invasive anatomic pulmonary resection. LB was tested for noninferiority on pain scores and opioid consumption. If LB was noninferior, superiority of LB was tested on both outcomes. SETTING: Academic tertiary care medical center. PARTICIPANTS: Adult patients undergoing minimally invasive anatomic pulmonary resection. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: For the secondary analysis, hospital length of stay was compared through the Cox regression model. Of 396 patients, 178 (45%) received LB and 218 (55%) did not. The mean (standard deviation) pain score was three (one) in the LB group and three (one) in the control group, with a difference of -0.10 (97.5% confidence interval [-0.39 to 0.18]; pâ¯=â¯0.41). The mean (standard deviation) cumulative opioid consumption (intravenous morphine equivalents) was 198 (208) mg in the LB group and 195 (162) mg in the control group. Treatment effect in opioid consumption was estimated at a ratio of geometric mean of 0.94 (97.5% confidence interval [0.74-1.20]; pâ¯=â¯0.56). Pain control and opioid consumption were noninferior with LB but not superior. Hospital discharge was not different between groups. CONCLUSIONS: LB with bupivacaine in ICNBs did not demonstrate superior postoperative analgesia or affect the rate of hospital discharge.

BACKGROUND: Projections based on regulations curtailing asbestos use in the USA suggest that peak incidence of pleural mesothelioma would occur between 2000 and 2005 and then decline. We analyzed the National Cancer Database (NCDB) to assess current trends in disease incidence, patient demographics, cancer treatment, and survival. METHODS: The NCDB was queried to identify patients diagnosed with pleural mesothelioma from 2004 through 2014. Clinical and pathologic characteristics, treatments, and survival were analyzed. Risk factors for death were identified by multivariable Cox regression. RESULTS: A total of 20,988 patients with pleural mesothelioma were reported to the NCDB. The number of cases per year increased from 1783 to 1961, accounting for roughly 0.3% of all reported cancers each year. The proportion of elderly patients increased from 75 to 80%, but distribution by sex remained constant (20% female). The proportion of patients undergoing treatment increased from 34 to 54%. One-year survival increased from 37 to 47% and 3-year survival from 9 to 15% (p < 0.001). Factors associated with improved survival included younger age, female sex, epithelioid histology, treatment in an academic center, health insurance, higher income, and multimodality therapy. CONCLUSIONS: The annual incidence of mesothelioma has not declined this century and remains stable. Reporting of histologic and clinical staging has improved. National trends suggest that survival is slowly increasing despite an aging cohort. Multimodal therapy and treatment at academic centers are modifiable risk factors associated with improved survival.

RESUMO
PURPOSE: Atrial arrhythmias are common after non-cardiac thoracic surgery. We tested the hypothesis that TEA reduces the risk of new-onset atrial arrhythmias after pulmonary resection. METHODS: We evaluated patients who had pulmonary resection. New-onset atrial arrhythmias detected before hospital discharge was our primary outcome. Secondary outcomes included other cardiovascular complications, pulmonary complications, time-weighted average pain score over 72 h, and duration of hospitalization. Patients with combination of general anesthesia and TEA were matched on propensity scores with patients given general anesthesia only. The matched groups were compared by use of logistic regression, linear regression, or Cox proportional hazards regression, as appropriate. RESULTS: Among 1,236 patients who had pulmonary resections, 937 received a combination of general anesthesia and TEA (TEA) and 299 received general anesthesia only (non-TEA). We successfully matched 311 TEA patients with 132 non-TEA patients. We did not find a significant association between TEA and postoperative atrial arrhythmia (odds ratio (95 % CI) of 1.05 (0.50, 2.19), P = 0.9). TEA was not significantly associated with length of hospital stay or postoperative pulmonary complications (odds ratio (95 % CI) of 0.71 (0.22, 2.29), P = 0.47). TEA patients experienced fewer postoperative cardiovascular complications; although the association was not statistically significant (odds ratio (95 % CI) of 0.30 (0.06, 1.45), P = 0.06). Time-weighted average pain scores were similar in the two groups. CONCLUSION: TEA was not associated with reduced occurrence of postoperative atrial arrhythmia. Although postoperative pulmonary complications were similar with and without TEA, TEA patients tended to experience fewer cardiovascular complications.

BACKGROUND: Open cervical parathyroidectomy is the standard of care for the treatment of primary hyperparathyroidism (PHP). However, in patients with a history of keloid or hypertrophic scar formation, the cosmetic result may sometimes be unsatisfactory. Furthermore, in the presence of mediastinal glands, a more morbid approach is sometimes necessary, involving a sternal split or thoracotomy. Robotic parathyroidectomy, either transaxillary or transthoracic, could be an alternative in both settings. METHODS: Between 2008 and 2013, 14 patients with PHP and a well-localized single adenoma underwent robotic transaxillary cervical (TAC) (n = 8) or transthoracic mediastinal (TTM) (n = 6) parathyroidectomy at an academic tertiary medical center and their outcomes were analyzed. RESULTS: All 14 operations were completed successfully as planned. For TAC and TTM parathyroidectomies, mean operative time was 184 and 168 min, respectively. With the exception of one TTM patient, intraoperative PTH determination indicated a >50 % drop in all patients 10 min after excision and no patients presented with recurrent disease on follow-up. Average length of hospital stay was 1 day after TAC parathyroidectomy and 2.2 days after TTM. On a visual analog pain scale (0-10), average pain scores after TAC were 6/10 on postoperative day 1 and 1/10 on day 14, compared to 7.7/10 and 1.5/10, respectively, after TTM. Complications included development of seroma in 1 patient in the TAC group and pericardial and pleural effusion in 1 patient in the TTM cohort. CONCLUSIONS: This initial study shows that robotic TAC and TTM parathyroidectomy are feasible in selected PHP patients with preoperatively well-localized disease. Although the TAC approach offers a potential cosmetic benefit in patients with a history of keloid or hypertrophic scar formation, a more generalized use cannot be recommended based on current evidence. The robotic TTM approach presents a minimally invasive alternative to resections previously performed through thoracotomy and sternotomy.

OBJECTIVE: In order to predict at hospital admission the prognosis of patients with serious and life-threatening COVID-19 pneumonia, we sought to understand the clinical characteristics of hospitalised patients at admission as the SARS-CoV-2 pandemic progressed, document their changing response to the virus and its variants over time, and identify factors most importantly associated with mortality after hospital admission. DESIGN: Observational study using a prospective hospital systemwide COVID-19 database. SETTING: 15-hospital US health system. PARTICIPANTS: 26 872 patients admitted with COVID-19 to our Northeast Ohio and Florida hospitals from 1 March 2020 to 1 June 2022. MAIN OUTCOME MEASURES: 60-day mortality (highest risk period) after hospital admission analysed by random survival forests machine learning using demographics, medical history, and COVID-19 vaccination status, and viral variant, symptoms, and routine laboratory test results obtained at hospital admission. RESULTS: Hospital mortality fell from 11% in March 2020 to 3.7% in March 2022, a 66% decrease (p<0.0001); 60-day mortality fell from 17% in May 2020 to 4.7% in May 2022, a 72% decrease (p<0.0001). Advanced age was the strongest predictor of 60-day mortality, followed by admission laboratory test results. Risk-adjusted 60-day mortality had all patients been admitted in March 2020 was 15% (CI 3.0% to 28%), and had they all been admitted in May 2022, 12% (CI 2.2% to 23%), a 20% decrease (p<0.0001). Dissociation between observed and predicted decrease in mortality was related to temporal change in admission patient profile, particularly in laboratory test results, but not vaccination status or viral variant. CONCLUSIONS: Hospital mortality from COVID-19 decreased substantially as the pandemic evolved but persisted after hospital discharge, eclipsing hospital mortality by 50% or more. However, after accounting for the many, even subtle, changes across the pandemic in patients' demographics, medical history and particularly admission laboratory results, a patient admitted early in the pandemic and predicted to be at high risk would remain at high risk of mortality if admitted tomorrow.

BACKGROUND: Type I achalasia comprises 20% of achalasia and has nearly absent esophageal motor activity. Concerns that fundoplication decreases the effectiveness of Heller myotomy in these patients has increased adoption of peroral endoscopic myotomy (POEM). Hence, we compared outcomes after Heller myotomy with Dor fundoplication vs POEM. METHODS: From 2005 to 2020, 150 patients with type I achalasia underwent primary surgical myotomy (117 Heller myotomy, 33 POEM). Patient demographics, prior treatments, timed barium esophagrams, Eckardt scores, and reinterventions were assessed between the 2 groups. Median follow-up was 5 years for Heller myotomy and 2.5 years for POEM. RESULTS: The Heller myotomy group was younger, had fewer comorbidities, and lower body mass index vs POEM. Risk-adjusted models demonstrated clinical success (Eckardt ≤3) in 83% of Heller myotomies and 87% of POEMs at 3 years; longitudinal complete timed barium esophagram emptying and reintervention were also similar. An abnormal pH test result was documented in 10% (6 of 60) after Heller myotomy and in 45% (10 of 22) after POEM (P < .001). CONCLUSIONS: Despite nearly absent esophageal contractility, Heller myotomy with Dor fundoplication and POEM result in similar long-term symptom relief, esophageal emptying, and occurrence of reintervention in patients with type I achalasia. There is decreased esophageal acid exposure with the addition of a fundoplication, without compromised esophageal drainage, allaying fears of a detrimental effect of a fundoplication. Hence, choice of procedure may be personalized based on patient characteristics and esophageal morphology and not solely on manometric subtype.

OBJECTIVES: We hypothesized that emergency complications related to asymptomatic paraconduit hernias may occur less often than generally believed. Therefore, we assessed the occurrence and timing of paraconduit hernia diagnosis after esophagectomy, as well as outcomes of these asymptomatic patients managed with a watch-and-wait approach. METHODS: From 2006 to 2021, 1214 patients underwent esophagectomy with reconstruction at the Cleveland Clinic. Among these patients, computed tomography scans were reviewed to identify paraconduit hernias. Medical records were reviewed for timing of hernia diagnosis, hernia characteristics, and patient symptoms, complications, and management. During this period, patients with asymptomatic paraconduit hernias were typically managed nonoperatively. RESULTS: Paraconduit hernias were identified in 37 patients. Of these, 31 (84%) had a pre-esophagectomy hiatal hernia. Twenty-one hernias (57%) contained colon, 7 hernias (19%) contained pancreas, and 9 hernias (24%) contained multiple organs. Estimated prevalence of paraconduit hernia was 3.3% at 3 years and 7.7% at 10 years. Seven patients (19%) had symptoms, 4 of whom were repaired electively, with 2 currently awaiting repairs. No patient with a paraconduit hernia experienced an acute complication that required emergency intervention. CONCLUSIONS: The risk of paraconduit hernia increases with time, suggesting that long-term symptom surveillance is reasonable. Emergency complications as a result of asymptomatic paraconduit hernias are rare. A small number of patients will experience hernia-related symptoms, sometimes years after hernia diagnosis. Our findings suggest that observation of asymptomatic paraconduit hernias (watch and wait) may be considered, with repair considered electively in patients with persistent symptoms.

BACKGROUND: Open approaches for esophagectomy are often still useful; of these, left thoracoabdominal esophagectomy (TAE) is poorly understood and often criticized. Hence, we examined TAE's worldwide utilization, survival, and present-day use and outcomes at our institution compared with contemporary national averages. METHODS: The Worldwide Esophageal Cancer Collaboration database includes 8854 patients who underwent esophagectomy for cancer between 2005 and 2014, a period when TAE was our center's most common approach. Two propensity score-matched models were constructed: worldwide TAE vs worldwide non-TAE (751 matched pairs); and our high-volume center TAE vs worldwide non-TAE (273 matched pairs). All-cause mortality was compared between matched groups. Institutional TAE data from 2017 to 2021 were assessed for present-day use and outcomes. RESULTS: Worldwide, propensity score-matched patients undergoing TAE had a median of 20 lymph nodes resected vs 17 after non-TAE (P < .0001). Five-year survival was 34% for worldwide TAE vs 42% for worldwide non-TAE groups (P = .04). Three-year matched survival was 52% for high-volume TAE compared with 54% for worldwide non-TAE groups (P = .1). From 2017 to 2021 at our institution, 90 (26%) of 346 esophagectomies were performed by TAE. Pneumonia developed in 5 patients (5.6%), with 88 patients (98%) alive at 30 days, comparable to contemporary averages of The Society of Thoracic Surgeons. CONCLUSIONS: When it is performed as the primary approach in high volumes, TAE can have comparable outcomes to non-TAE with low morbidity. At present, we find that TAE is most useful in patients with truncal obesity, prior abdominal operations, and locally advanced cardia tumors with potential for variable extent of resection.

OBJECTIVE: Currently, there is no validated patient-reported outcome measure (PROM) applicable to all esophageal diseases. Our objective was to create a psychometrically robust, validated universal esophageal PROM that can also objectively assess patients' quality of life (QoL). METHODS: The pilot PROM constructed based on expert opinions, literature review, and previous unpublished institutional research had 27 items covering 8 domains. It was completed by 30 patients in the outpatient clinic followed by a structured debriefing interview, which allowed for refining the PROM. The final PROM: Cleveland Clinic Esophageal Questionnaire (CEQ) included 34 items across 6 domains (Dysphagia, Eating, Pain, Reflux & Regurgitation, Dyspepsia, Dumping), each accompanied by a corresponding QoL component. Further psychometric assessment of the PROM was conducted by evaluating (1) acceptability, (2) construct validity, (3) reliability, and (4) responsiveness. RESULTS: Five hundred forty-six unique patients (median 63.7 years [54.3-71.7], 53% male [287], 86% White) completed CEQ at >90% completion within 5 minutes. Construct validity was demonstrated by differentiating scores across esophageal cancer (n = 146), achalasia (n = 170), hiatal hernia (n = 160), and other diagnoses (n = 70). Internal reliability (Cronbach alpha 0.83-0.89), and test-retest reliability (intraclass correlation coefficients 0.63-0.85) were strong. Responsiveness was demonstrated through CEQ domains improving for 53 patients who underwent surgery for achalasia or hiatal hernia (Cohen d 0.86-2.59). CONCLUSIONS: We have constructed a psychometrically robust, universal esophageal PROM that allows concise, consistent, objective quantification of symptoms and their effect on the patient. The CEQ is valuable in prognostication and tracking of longitudinal outcomes in both benign and malignant esophageal diseases.

BACKGROUND: Inaccuracy of clinical staging renders management of clinical T2 N0 M0 (cT2 N0 M0) esophageal cancer difficult. When an underlying advanced-stage disease is understaged to cT2 N0 M0, patients miss the opportunity to gain the potential benefits of neoadjuvant therapy. This study aimed to identify preoperative factors that predict underlying advanced-stage esophageal cancer. METHODS: From 2000 to 2020, 1579 patients with esophageal cancer underwent esophagectomy. Sixty patients who underwent upfront surgery for cT2 N0 M0 esophageal cancer were included in this study. The median age was 62.5 years, and 78% (n = 47) of these patients were male. Radiologic, clinical, and endoscopic factors were evaluated as preoperative markers. The Fisher exact and the Wilcoxon rank sum tests were used for categoric and continuous variables, respectively. Random forest classification was used to identify preoperative factors for predicting upstaging and downstaging. RESULTS: Of the 60 patients, 8 (13%) were found to have pathologic T2 N0 M0 esophageal cancer. Sixteen (27%) patients had cancer that was pathologically downstaged, and 36 (60%) had upstaged disease. Seven (19%) patients had upstaged cancer on the basis of the pathologic T stage, 14 (39%) had upstaging on the basis of the pathologic N stage, and 15 (42%) had upstaging on the basis of both T and N stages. Dysphagia (P = .003) and tumor maximum standardized uptake value (P = .048) were predictors of upstaging, with a combined predictive value of up to 75%. CONCLUSIONS: The presence of dysphagia and of high maximum standardized uptake value (≥5) of the tumor is predictive of more advanced underlying disease for patients with cT2 N0 M0 esophageal cancer, and these patients should be considered for neoadjuvant therapy.

BACKGROUND: Heparin is routinely administered to brain-dead donors before cardiac arrest, although it is not universally allowed for donation after cardiac death (DCD) donors due to concerns that death may be hastened. The lack of heparin may lead to thrombosis and compromised graft function. We evaluated the impact of timing of heparin administration and thrombi formation in a DCD pig model. METHODS: Eight domestic adult pigs were administered systemic heparin (30,000 IU): four prior to cardiac arrest through intravenous injection (prearrest heparin) and four after cardiac arrest via injection into the right atrium followed by open cardiac massage (postarrest heparin). Pigs were euthanized with potassium chloride and a minimum of 5 minutes of cardiac silence allowed before organ procurement. Lungs were flushed with antegrade and retrograde Perfadex, and pulmonary preservation solution effluent was evaluated for gross thrombi. Organs were fixed in formalin, sagittally sectioned, and evaluated by a pulmonary pathologist blinded to treatment. RESULTS: Antegrade and retrograde flushes demonstrated no significant thrombi. Gross pathologic evaluation revealed no occlusive central thrombi. Scant peripheral thrombi were detected in both treatment groups. No microscopic thrombi were noted in either treatment group. CONCLUSIONS: Delayed heparin administration after cardiac death does not affect thrombus formation in an animal model of lung procurement after cardiac death. Concern about clinically significant thrombosis occurring when heparin is not given before cardiac arrest appears unfounded. These findings suggest that DCD lungs can be used regardless of antemortem heparin administration.

OBJECTIVE: Spread through air spaces (STAS) is a new histologic feature of invasion of non-small cell lung cancer that lacks sensitivity and specificity on frozen sections and is associated with higher recurrence and worse survival with sublobar resections. Our objective is to identify preoperative characteristics that are predictive of STAS to guide operative decisions. METHODS: From January 2018 through December 2021, 439 cT1-3N0 M0 patients with non-small cell lung cancer and a median age of 68 years, 255 (58%) women, who underwent primary surgery at our institution were included. Patients who received neoadjuvant therapy and whose STAS status was not documented were excluded. Age, sex, smoking status, tumor size, ground-glass opacities, maximum standardized uptake values, and molecular markers on preoperative biopsy were evaluated as preoperative markers. Comparisons between groups were conducted using standardized mean differences and random forest classification was used for prediction modeling. RESULTS: Of the 439 patients, 177 had at least 1 STAS-positive tumor, and 262 had no STAS-positive tumors. Overall, 179 STAS tumors and 293 non-STAS tumors were evaluated. Younger age (50 years or younger), solid tumor, size ≥2 cm, and maximum standardized uptake value ≥2.5 were independently predictive of STAS with prediction probabilities of 50%, 40%, 38%, and 40%, respectively. STAS tumors were more likely to harbor KRAS mutations and be PD-L1 negative. CONCLUSIONS: Young age (50 years or younger), larger (≥2 cm) solid tumors, high maximum standardized uptake values, and presence of KRAS mutation, are risk factors for STAS and can be considered for lobectomy. Smoking status and gender are still controversial risk factors for STAS.
RESUMO
BACKGROUND: There is a limited experience using pediatric organs for adult lung transplantation (LTx), with size matching the major concern. We reviewed our experience transplanting pediatric donor lungs into adult recipients with endpoints of post-LTx complications and overall patient survival. METHODS: From 2/1990 to 12/2007, 609 adults underwent primary LTx at our institution. Thirty-eight (6.2%) patients underwent LTx with organs from pediatric donors (≤16 years). Of these, median donor age was 13 years (range: 7 to 16) and median recipient age 55 (range: 24 to 66). Endpoints analyzed included size matching accuracy, airway and pleural complications, time to extubation, intensive care unit (ICU) and hospital lengths of stay, as well as survival. RESULTS: Gross undersizing of the donor lung was present in 2/38 (5.3%) and of the donor bronchus in 11/38 (29%). Five patients (13%) experienced a major postoperative airway complication. Thoracentesis prior to discharge was necessary in 4/38 (11%) patients and chest tube reinsertion in 10/38 (26%) for pleural effusion. Median time to extubation was 2 days. ICU and hospital lengths of stay were 6 and 16 days, respectively. Kaplan-Meier survival at 30 days, 1 year, 3 years, and 5 years post-transplant was 89%, 74%, 63%, and 55%. CONCLUSIONS: Despite sizing concerns, transplantation of pediatric lungs into adult recipients is feasible. Size mismatch may predispose to higher rates of airway and pleural complications. Hospital course and overall survival appear comparable to adult-to-adult LTx, and concerns over size matching should not preclude pediatric organ use for adult candidates.

Objectives: Currently, more than 36% of patients diagnosed with lung cancer are 75 years of age or older. Management of stage IIIA cancer is variable, especially for octogenarians who might not be offered surgery because of questionable benefit. In this study we investigated the outcomes of definitive chemoradiotherapy (CR) and trimodality therapy (TM) management (CR and surgery) for clinical stage IIIA non-small cell lung cancer (NSCLC) in patients 80 years of age or older. Methods: The National Cancer Data Base was queried for stage IIIA NSCLC in patients 80 years of age or older between 2004 and 2015. Patients were divided according to treatment type: definitive CR and TM. Patient demographic characteristics, facility type, Charlson-Deyo score, final tumor pathology, and survival data were extracted. Univariate analysis was performed, followed by 3:1 propensity matching to analyze overall survival differences. Unadjusted and adjusted Kaplan-Meier survival analyses were performed. Results: From the database, 6048 CR and 190 TM octogenarians were identified. Patients in the TM group were younger (82 years old [TM] vs 83 years old [CR]; P < .0001), more likely to be treated at an academic/research institution (36% [TM] vs 26% [CR]; P = .003), had greater proportion of adenocarcinoma (52% [TM] vs 34% [CR]; P < .001), and a smaller tumor size (38 mm [TM] vs 33 mm [CR]; P = .025). After 3:1 matching, the 5-year overall survival for the TM group was 29% (95% CI, 22%-38%) versus 15% (95% CI, 11%-20%) for the CR group. Conclusions: Selected elderly patients with stage IIIa NSCLC can benefit from an aggressive TM approach.
