Tracheal resection and primary reconstruction on venovenous extracorporeal membrane oxygenation.

Cross-table ventilation during tracheal resection via posterolateral thoracotomy presents a technical challenge. With the ubiquity of venovenous extracorporeal membrane oxygenation (VV-ECMO), there is now a safe and feasible alternative for intraoperative respiratory support. Airway surgery on ECMO avoids prolonged periods of apnea or single lung ventilation, allowing patients with poor lung function to undergo surgery. Image-guided femoro-femoral cannulation using a low-dose heparin protocol minimizes the risk of bleeding while uncluttering the surgical field. By eliminating the need to constantly reposition the endotracheal tube, visualization is improved, and the rhythm of the case is maintained, which can shorten the anastomotic time. Here, we present a case where venovenous ECMO and total intravenous anesthesia were used to completely support a patient undergoing major tracheal surgery without the need for cross-table ventilation.

Trimodality Therapy in the Treatment of Stage III N2-Positive Non-Small Cell Lung Cancer: A National Cancer Database Analysis.

BACKGROUND: Significant controversy remains regarding the care of patients with clinical stage III (N2-positive) NSCLC. Although multimodality therapy is effective, the roles of surgery, chemotherapy, and radiotherapy are not fully defined and the optimal treatment approach is not firmly established. We analyzed outcomes and predictors associated with trimodality therapy (TT) in the National Cancer Database. MATERIALS AND METHODS: The NCDB was queried from 2004 to 2014 for patients with NSCLC diagnosed with stage III (N2) disease and treated with chemotherapy and radiation (CRT). Three cohorts of patients were studied: CRT only/no surgery (NS), CRT plus lobectomy (LT), and CRT plus pneumonectomy (PT). The univariate and multivariable analyses (MVA) were conducted using Cox proportional hazards model and log-rank tests. RESULTS: A total of 29,754 patients were included in this analysis: NS 90.1%, LT 8.4%, and PT 1.5%. Patient characteristics: median age 66 years; male 56% and white 85%. Patients treated at academic centers were more likely to receive TT compared with those treated at community centers (odds ratio: 1.85 [1.53-2.23]; p < .001). On MVA, patients that received TT were associated with better survival than those that received only CRT (hazard ratio: 0.59 [0.55-0.62]; p < .001). The LT group was associated with significantly better survival than the PT and NS groups (median survival: 62.8 months vs. 51.8 months vs. 34.2 months, respectively). In patients with more than two nodes involved, PT was associated with worse survival than LT and NS (median survival: 51.4 months in LT and 39 months in NS vs. 37 months in PT). The 30-day and 90-day mortality rates were found to be significantly higher in PT patients than in LT. CONCLUSION: TT was used in less than 10% of patients with stage III N2 disease, suggesting high degree of patient selection. In this selected group, TT was associated with favorable outcomes relative to CRT alone. IMPLICATIONS FOR PRACTICE: This analysis demonstrates that trimodality therapy could benefit a selected subset of patients with stage III (N2) disease. This plan should be considered as a treatment option following patient evaluation in a multidisciplinary setting in experienced medical centers with the needed expertise.

Evaluation of a Powered Vascular Stapler in Video-Assisted Thoracic Surgery Lobectomy.

BACKGROUND: A narrow-profile powered vascular stapler (PVS) was developed to provide superior access and precise staple placement in thoracic procedures. The objective of this study was to determine if the PVS would yield an equivalent rate of hemostatic interventions compared with standard of care (SOC) staplers in video-assisted thoracoscopic surgery lobectomy. MATERIALS AND METHODS: A randomized, controlled, multicenter study was conducted comparing PVS with SOC staplers in lobectomies performed for non-small cell lung cancer. The primary performance endpoint was the incidence of intraoperative hemostatic interventions, and the primary safety endpoint was the frequency of postoperative bleeding-related interventions. RESULTS: A total of 98 subjects participated in the SOC group and 103 in the PVS group. Rates of intraoperative hemostatic interventions were 5.3% and 8.3% for the SOC and PVS groups, respectively. These rates were not statistically different (P = 0.137), although the upper bound of the 95% confidence interval for the difference in intervention rates between PVC and SOC exceeded a predefined 3% criterion for equivalence. Simple compressions were performed more frequently in the PVS subjects, which accounted for the higher intervention rate in this group. Postoperative interventions for bleeding were required in one SOC subject (1.0%) and one subject from the PVS group (0.9%). Procedure-related adverse events occurred in 21 (21.9%) SOC subjects and 23 (21.9%) PVS subjects, with no adverse events related to use of the study devices. CONCLUSIONS: The PVS exhibited similar overall safety and effectiveness to SOC staplers in video-assisted thoracoscopic surgery lobectomy.

Health care disparities among octogenarians and nonagenarians with stage III lung cancer.

BACKGROUND: To the authors' knowledge, the practice patterns for patients aged more than 80 years with stage III non-small cell lung cancer (NSCLC) is not well known. The purpose of the current study was to investigate factors predictive of and the impact on overall survival (OS) after concurrent chemoradiation (CRT) among patients aged ≥80 years with American Joint Committee on Cancer stage III NSCLC in the National Cancer Data Base (NCDB). METHODS: In the NCDB, patients aged ≥80 years who were diagnosed with stage III NSCLC from 2004 to 2013 with complete treatment records were identified. Multivariable logistic regression and Cox proportional hazard models were generated and propensity score-matched analysis was used. RESULTS: A total of 12,641 patients met the entry criteria: 6018 (47.6%) had stage IIIA disease and 6623 (52.4%) had stage IIIB disease. The median age at the time of diagnosis was 83.0 years (range, 80-91 years). A total of 7921 patients (62.7%) received no therapy. Black race (odds ratio [OR], 1.23; 95% confidence interval [95% CI], 1.06-1.43) and living in a lower educated census tract of residence (OR, 1.20; 95% CI, 1.03-1.40) were found to be associated with not receiving care, whereas treatment at an academic center (OR, 0.80; 95% CI, 0.70-0.92) was associated with receiving cancer-directed therapy. Receipt of no treatment (hazard ratio [HR], 2.69; 95% CI, 2.57-2.82) or definitive radiation alone (HR, 1.15; 95% CI, 1.07-1.24) compared with CRT was associated with worse OS. On propensity score matching, not receiving CRT was found to be associated with worse OS (HR, 1.58; 95% CI, 1.44-1.72). CONCLUSIONS: In this NCDB analysis, approximately 62.7% of patients aged ≥80 years with stage III NSCLC received no cancer-directed care. Black race and living in a lower educated census tract were associated with not receiving cancer-directed care. OS was found to be improved in patients receiving CRT.

Concurrent chemoradiotherapy with or without surgery for patients with resectable esophageal cancer: An analysis of the National Cancer Data Base.

BACKGROUND: Patients with resectable esophageal cancer (rEC) are managed with either concurrent chemoradiotherapy followed by surgery (CRSx) or concurrent chemoradiotherapy alone (cCR). To the authors' knowledge, there is insufficient evidence comparing the overall survival of patients treated with these 2 options. METHODS: The National Cancer Data Base was queried for rEC cases diagnosed from 2003 through 2011. Patients with previous cancers, cervical rEC, clinical stage T1N0 disease, or metastasis were excluded. cCR was defined as radiotherapy administered within 30 days of chemotherapy. CRSx was defined as cCR followed by esophagectomy within 90 days. Overall survival was compared using Kaplan-Meier methods, propensity score matching, and extended Cox proportional hazards models. RESULTS: Of the 11,122 eligible patients, 8091 (72.7%) received cCR and 3031 (27.3%) received CRSx. The odds of receiving CRSx were higher among patients with American Joint Committee on Cancer stage II disease (vs stage III), adenocarcinoma (vs squamous cell carcinoma), lesions of the lower one-third of the esophagus, private insurance, and those living >25 miles from the treating facility or in areas with a higher median income or a greater percentage of high school-educated residents. Patients aged >70 years, female patients, African-American patients, those with ≥2 comorbidities, or those treated at community programs were more likely to receive cCR. After propensity score matching, the median and 10-year survival rates were found to be significantly better with CRSx (32.5 months [95% confidence interval (95% CI), 29.6-34.8 months] and 23.8% months [95% CI, 20.0-27.9 months], respectively) compared with cCR (14.2 months [95% CI, 13.4-15.5 months] and 6.1% months [95% CI, 3.9-9.0 months], respectively). CONCLUSIONS: Data from the National Cancer Data Base support the inclusion of surgery after concurrent chemoradiotherapy for patients with locally advanced rEC.

Next-generation sequencing and clinical outcomes of patients with lung adenocarcinoma treated with stereotactic body radiotherapy.

BACKGROUND: Genetic aberrations are well characterized in lung adenocarcinomas (LACs) and clinical outcomes have been influenced by targeted therapies in the advanced setting. Stereotactic body radiotherapy (SBRT) is the standard-of-care therapy for patients with nonoperable, early-stage LAC, but to the authors' knowledge, no information is available regarding the impact of genomic changes in these patients. The current study sought to determine the frequency and clinical impact of genetic aberrations in this population. METHODS: Under an Institutional Review Board-approved protocol, the records of 242 consecutive patients with early-stage lung cancers were reviewed; inclusion criteria included LAC histology with an adequate tumor sample for the successful use of next-generation sequencing and fluorescence in situ hybridization testing. Univariate analysis was performed to identify factors associated with clinical outcomes. RESULTS: LAC samples from 98 of the 242 patients were reviewed (40.5%), of whom 45 patients (46.0%) had genetic testing. The following mutations were noted: KRAS in 20.0% of samples, BRAF in 2.2% of samples, SMAD family member 4 (SMAD4) in 4.4% of samples, epidermal growth factor receptor (EGFR) in 15.6% of samples, STK1 in 2.2% of samples, tumor protein 53 (TP53) in 15.6% of samples, and phosphatase and tensin homolog (PTEN) in 2.2% of samples. The following gene rearrangements were observed: anaplastic lymphoma kinase (ALK) in 8.9% of samples, RET in 2.2% of samples, and MET amplification in 17.8% of samples. The median total delivered SBRT dose was 50 grays (range, 48-60 grays) over a median of 5 fractions (range, 3-8 fractions). The KRAS mutation was associated with worse local control (odds ratio [OR], 3.64; P<.05). MET amplification was associated with worse regional (OR, 4.64; P<.05) and distant (OR, 3.73; P<.05) disease control. CONCLUSIONS: To the authors' knowledge, the current series is the first to quantify genetic mutations and their association with clinical outcomes in patients with early-stage LAC treated with SBRT. KRAS mutations were associated with worse local control and MET amplification was associated with worse regional and distant disease control, findings that need to be validated in a prospective setting.

Treatment allocation in patients with early-stage esophageal adenocarcinoma: Prevalence and predictors of lymph node involvement.

BACKGROUND: In considering treatment allocation for patients with early esophageal adenocarcinoma, the incidence of lymph node metastasis is a critical determinant; however, this has not been well defined or stratified by the relevant clinical predictors of lymph node spread. METHODS: Data from the Surveillance, Epidemiology, and End Results database of the National Cancer Institute were abstracted from 2004 to 2010 for patients with early-stage esophageal adenocarcinoma. The incidence of lymph node involvement for patients with Tis, T1a, and T1b tumors was examined and was stratified by predictors of spread. RESULTS: A total of 13,996 patients with esophageal adenocarcinoma were evaluated. Excluding those with advanced, metastatic, and/or invasive (T2-T4) disease, 715 patients with Tis, T1a, and T1b tumors were included. On multivariate analysis, tumor grade (odds ratio [OR], 2.76; 95% confidence interval [95% CI], 1.58-4.82 [P<.001]), T classification (OR, 0.47; 95% CI, 0.24-0.91 [P =.025]), and tumor size (OR, 2.68; 95% CI, 1.48-4.85 [P = .001]) were found to be independently associated with lymph node metastases. There was no lymph node spread noted with Tis tumors. For patients with low-grade (well or moderately differentiated) tumors measuring <2 cm in size, the risk of lymph node metastasis was 1.7% for T1a (P<.001) and 8.6% for T1b (P = .001) tumors. CONCLUSIONS: For patients with low-grade Tis or T1 tumors measuring ≤2 cm in size, the incidence of lymph node metastasis appears to be comparable to the mortality rate associated with esophagectomy. For highly selected patients with early esophageal adenocarcinomas, the results of the current study support the recommendation that local endoscopic resection can be considered as an alternative to surgical management when followed by rigorous endoscopic and radiographic surveillance.

Transthoracic versus transhiatal resection for esophageal adenocarcinoma of the lower esophagus: A value-based comparison.

BACKGROUND AND OBJECTIVE: Our objective was to compare clinical outcomes, costs, and resource use based on operative approach, transthoracic (TT) or transhiatal (TH), for resection of esophageal cancer. METHODS: This cohort analysis utilized the Surveillance, Epidemiology, and End Results--Medicare linked data from 2002 to 2009. Only adenocarcinomas of the lower esophagus were examined to minimize confounding. Medicare data was used to determine episode of care costs and resource use. Propensity score matching was used to control for identified confounders. Kaplan-Meier method and Cox-proportional hazard modeling were used to compare long-term survival. RESULTS: 537 TT and 405 TH resections were identified. TT and TH esophagectomy had similar complication rates (46.7% vs. 50.8%), operative mortality (7.9% vs 7.1%), and 90 days readmission rates (30.5% vs. 32.5%). However, TH was associated with shorter length of stay (11.5 vs. 13.0 days, P = 0.006) and nearly $1,000 lower cost of initial hospitalization (P = 0.03). No difference in 5-year survival was identified (33.5% vs. 36%, P = 0.75). CONCLUSIONS: TH esophagectomy was associated with lower costs and shorter length of stay in an elderly Medicare population, with similar clinical outcomes to TT. The TH approach to esophagectomy for distal esophageal adenocarcinoma may, therefore, provide greater value (quality/cost).

Routine Implementation of Patient-Reported Outcomes Assessment Into Thoracic Surgery Practice.

BACKGROUND: Patient-reported outcomes (PROs) assessment is a necessary component of surgical outcome assessment and patient care. This study examined the success of routine PROs assessment in an academic-based thoracic surgery practice. METHODS: PROs, measuring pain intensity, physical function, and dyspnea, were routinely obtained using the National Institutes of Health-sponsored Patient-Reported Outcomes Measurement Information System (PROMIS) on all thoracic surgery patients beginning in April 2018 through January 2021. Questionnaires were administered electronically through a web-based platform at home or during the office visit. Completion rates and barriers were measured. RESULTS: A total of 9725 thoracic surgery office visits occurred during this time frame. PROs data were obtained in 6899 visits from a total of 3551 patients. The mean number of questions answered per survey was 22.4 ± 2.2. Overall questionnaire completion rate was 65.7%. A significant decline in survey completion was noted in April 2020, after which adjustments were made to allow for questionnaire completion through a mobile health platform. Overall monthly questionnaire completion rates ranged from 20% (April 2020) to 90% (October 2018). Mean T scores were dyspnea, 41.6 ± 12.3; physical function, 42.7 ± 10.5; and pain intensity, 52.8 ± 10.3. CONCLUSIONS: PROs can be assessed effectively in a thoracic surgery clinic setting, with minimal disruption of clinical activities. Future efforts should focus on facilitating PROs collection from disadvantaged patient populations and scaling implementation across programs.

Recovery of Patient-reported Quality of Life After Esophagectomy.

BACKGROUND: Esophagectomy is an important, but potentially morbid, operation used to treat benign and malignant conditions that may significantly impact patient quality of life (QOL). Patient-reported outcomes (PROs) are measures of QOL that come directly from patient self-report. This study characterizes patterns of change and recovery in PROs in the first year after esophagectomy. METHODS: Longitudinal QOL scores measuring physical function, pain, and dyspnea were obtained from esophagectomy patients during all clinic visits. PRO scores were obtained using the National Institutes of Health-sponsored Patient-Reported Outcomes Measurement Information System from April 2018 to February 2021. Mean PRO scores over 100 days after surgery were compared with baseline PRO scores using mixed-effects modeling with compound symmetry correlational structure. RESULTS: One hundred three patients with PRO results were identified. Reasons for esophagectomy were malignancy (87.4%), achalasia (5.8%), stricture (5.8%), and dysplasia (1.0%). When comparing mean PRO scores at visits ≤ 50 days after surgery with preoperative PRO scores, physical function scores declined by 27.3% (P < .001), whereas dyspnea severity and pain interference scores had increased by 24.5% (P < .001) and 17.1% (P < .001), respectively. Although recovery occurred over the course of the 100 days after surgery, mean physical function scores and dyspnea scores were still 12.7% (P = .02) and 26.4% (P = .001) worse, respectively, than mean preoperative levels. CONCLUSIONS: Despite declines in QOL scores immediately after esophagectomy, recovery back toward baseline was observed during the first 100 days. These findings are of considerable importance when counseling patients regarding esophagectomy, tracking recovery, and implementing quality improvement initiatives. Further long-term follow-up is needed to determine recovery beyond 100 days.

Epidemiology of early esophageal adenocarcinoma.

BACKGROUND/AIMS: Endoscopic resection has become the preferred treatment approach for select early esophageal adenocarcinoma (EAC); however, the epidemiology of early stage disease has not been well defined. METHODS: Surveillance Epidemiology and End Results (SEER) data were analyzed to determine age-adjusted incidence rates among major epithelial carcinomas, including EAC, from 1973 to 2017. The percent change in incidence over time was compared according to tumor subtype. Early T-stage, node-negative EAC without metastasis was examined from 2004 to 2017 when precise T-stage data were available. RESULTS: The percent change in annual incidence from 1973 to 2017 was 767% for EAC. Joinpoint analysis showed that the average annual percent change in EAC from 1973 to 2017 was 5.11% (95% confidence interval, 4.66%-5.56%). The annual percent change appeared to plateau between 2004 and 2017; however, early EAC decreased from 2010 to 2017, with an annual percent change of -5.78%. CONCLUSION: There has been a 7-fold increase in the incidence of EAC, which was significantly greater than that of the other major epithelial malignancies examined. More recently, the incidence of early EAC has been decreasing. Approximately one in five patients has node negative, potentially resectable early stage disease.

Durable complete response for oligometastatic renal cell carcinoma with immune checkpoint inhibition and cytoreductive nephrectomy in a Jehovah's witness: A case report.

The role of cytoreductive nephrectomy in patients with metastatic renal cell carcinoma is a subject of debate. We report a durable complete response in a 62-year-old man Jehovah's Witness with metastatic clear cell renal cell carcinoma who received two cycles of nivolumab/ipilimumab followed by radical nephrectomy and metastasectomy of known pulmonary disease site, both without a clinical need for perioperative blood transfusions. The patient continues to be without evidence of disease and without additional need for systemic therapy over a year after his radical nephrectomy. The case highlights that cytoreductive nephrectomy continues to play a role in the era of immune checkpoint inhibitors.

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.

Thoracic endovascular repair as a safe management strategy for aortobronchial fistulas.

OBJECTIVES: This study assessed the safety and efficacy of thoracic endovascular aortic repair (TEVAR) in the management of aortobronchial fistulas. METHODS: A retrospective review was performed at Emory University Hospital to identify all patients who presented with an aortobronchial fistula. The diagnosis was based on clinical, radiologic, and bronchoscopic findings. Patients who underwent TEVAR as definitive management of these fistulas were identified. Demographics, history of thoracic aorta pathology or intervention, type and number of endografts used, need for reoperation, and clinical and radiologic follow-up data were collected for each individual. RESULTS: Between 2000 and 2009, 11 patients received TEVAR as definitive management of aortobronchial fistulas. Technical success was achieved in 10 patients (91%). Six patients (55%) had previously undergone thoracic aortic surgery. A proximal type 1 endoleak developed in one patient after graft deployment and required reintervention for additional graft placement. No intraoperative or 30-day deaths occurred. Postoperative clinical and radiographic assessment was a mean of 8.8 months (range, 1-40 months). For all 10 patients in whom technical success was achieved at the initial operation, no endoleaks were noted at the follow-up CT scan. In addition, no patient required a further intervention. CONCLUSIONS: This study represents the largest reported series on the use of TEVAR in the management of aortobronchial fistulas. Supported by postoperative surveillance imaging and clinical evaluation, TEVAR has proven to be a safe and effective management strategy for an otherwise lethal condition. Long-term follow-up data are needed to ascertain the durability of this approach.

C-reactive protein may represent sensitive measure of renal cell carcinoma metastasis.

A patient with localized kidney cancer underwent potentially curative nephrectomy. Routinely post-operative serum C-Reactive Protein (CRP) values were measured. At 25 months post-operatively, lung imaging suggested possible metastasis. However, CRP levels remained at baseline. Subsequent resection revealed a benign mass. CRP values have been shown to carry prognostic significance for overall and disease free survival. This case suggests a novel use for CRP: a sensitive biomarker of disease recurrence and metastasis.

Safety and Feasibility of Thoracoscopic Lung Resection for Non-Small-Cell Lung Cancer in Octogenarians.

OBJECTIVE: Octogenarians comprise an increasing proportion of patients presenting with non-small-cell lung cancer (NSCLC). This study examines postoperative morbidity and mortality, and long-term survival in octogenarians undergoing thoracoscopic anatomic lung resection for NSCLC, compared with younger cohorts. METHODS: We conducted a retrospective review of our institutional Society of Thoracic Surgeons General Thoracic Surgery Database of all patients ≥60 years old undergoing elective lobectomy or segmentectomy for pathologic stage I, II, and IIIA NSCLC between 2009 and 2018. Results were compared between octogenarians (n = 71) to 2 younger cohorts of 60- to 69-year-olds (n = 359) and 70- to 79-year-olds (n = 308). Long-term survival among octogenarians was graphically summarized using the Kaplan-Meier method. Cox regression analysis was used to identify preoperative risk factors for mortality. RESULTS: A greater proportion of octogenarians required intensive care unit admission and discharge to extended-care facilities; however, postoperative length of stay was similar between groups. Among postoperative complications, arrhythmia and renal failure were more likely in the older cohort. Compared to the youngest cohort, in-hospital and 30-day mortality were highest among octogenarians. Overall survival among octogenarians at 1, 3, and 5 years was 87.3%, 61.8%, and 50.5%, respectively. On multivariable Cox regression analysis of baseline demographic variables, presence of stroke (hazard ratio [HR] = 28.5, 95% confidence interval [CI]: 6.1 to 132.7, P < 0.001) and coronary artery disease (HR = 2.5, 95% CI: 1.2 to 5.3, P = 0.02) were significant predictors of overall mortality among octogenarians. CONCLUSIONS: Thoracoscopic resection can be performed with favorable early postoperative outcomes among octogenarians. Long-term survival, although comparable to their healthy peers, is worse than those of younger cohorts. Further study into preoperative risk stratification and alternative therapies among octogenarians is needed.

Community Size and Lung Cancer Resection Outcomes: Studying The Society of Thoracic Surgeons Database.

BACKGROUND: Socioeconomic factors play key roles in surgical outcomes. Socioeconomic data within The Society of Thoracic Surgeons (STS) General Thoracic Surgery Database (GTSD) are limited. Therefore, we utilized community size as a surrogate to understand socioeconomic differences in lung cancer resection outcomes. METHODS: We retrospectively reviewed all lung cancer resections from January 2012 to January 2017 in the STS GTSD. This captured 68,722 patients from 286 centers nationwide. We then linked patient zip codes with 2013 Rural-Urban Continuum Codes to understand the association between community size and postoperative outcomes. Demographic and clinical variables were evaluated for relationships with 30-day mortality, major morbidity, and readmission. RESULTS: Zip codes were included in 47.2% of patients. Zip-coded patients were older, were more comorbid, had less advanced disease, and were more commonly treated with minimally invasive approaches than were those without zip code classification. For geocoded patients, multivariable analyses demonstrated that sex, insurance payor, and hospital region were associated with all 3 major endpoints. Community size, based on Rural-Urban Continuum Codes coding, was not associated with any primary endpoint. Invasive mediastinal staging was related to morbidity, greater pathological stage predicted mortality, and worsened clinical stage was associated with readmission. More invasive surgery and greater extent of lung resection were associated with all primary endpoints. CONCLUSIONS: Incomplete data capture can promote selection bias within the STS GTSD and skew outcomes reporting. Moreover, community size is an insufficient surrogate, compared with sex, insurance payor, hospital region, for understanding socioeconomic differences in lung cancer resection outcomes.

Preoperative Lung Function Is Associated With Patient-Reported Outcomes After Lung Cancer Surgery.

BACKGROUND: Patient quality of life (QOL) is a critical outcomes measure in lung cancer surgery. Patient-reported outcomes (PROs) provide valuable insight into the patient experience and allow measurement of preoperative and postoperative QOL. Our objective was to determine which clinical factors predict differences in QOL, as measured by patient-reported physical function and pain intensity among patients undergoing minimally invasive lung cancer surgery. METHODS: PRO surveys assessing physical function and pain intensity were conducted using instruments from the National Institutes of Health Patient-Reported Outcomes Measurement Information System. PRO surveys were administered to patients undergoing minimally invasive lung cancer resections at preoperative, 1-month, and 6-month postoperative time points, in an academic institution. Linear mixed-effects regression models were constructed to assess the association between clinical variables on PRO scores over time. RESULTS: A total of 123 patients underwent a thoracoscopic lung resection for cancer. Mean age of the cohort was 67 ± 9.6 years, 43% were male, and 80% were White. When comparing clinical variables with PRO scores after surgery, lower diffusing capacity of the lungs for carbon monoxide (Dlco) was associated with significantly worse physical function (P < .01) and greater pain intensity scores (P < .01) at 6 months, with no differences identified at 1 month. No other studied clinical factor was associated with significant differences in PRO scores. CONCLUSIONS: Low preoperative Dlco was associated with significant decreases in PRO after minimally invasive lung cancer surgery. Dlco may be of utility in identifying patients who experience greater decline in QOL after surgery and for guiding surgical decision making.

Association Between Patient Physical Function and Length of Stay After Thoracoscopic Lung Cancer Surgery.

Patient-reported outcomes (PRO) are an ideal method for measuring patient functional status. We sought to evaluate whether preoperative PRO were associated with resource utilization. We hypothesize that higher preoperative physical function PRO scores, measured via the NIH-sponsored Patient Reported Outcome Measurement Information System (PROMIS), are associated with shorter length of stay (LOS). Preoperative physical function scores were obtained using NIH PROMIS in a prospective observational study of patients undergoing minimally invasive surgery for lung cancer. Poisson regression models were constructed to estimate the association between the length of stay and PROMIS physical function T-score, adjusting for extent of resection, age, gender, and race. Due to the significant interaction between postoperative complications and physical function T-score, the relationship between physical function and LOS was described separately for each complication status. A total of 123 patients were included; 88 lobectomy, 35 sublobar resections. Mean age was 67 years, 35% were male, 65% were Caucasian. Among patients who had a postoperative complication, a lower preoperative physical function T-score was associated with progressively increasing LOS (P  value = 0.006). In particular, LOS decreased by 18% for every 10-point increase in physical function T-score. Among patients without complications, T-score was not associated with LOS (P = 0.86). Preoperative physical function measured via PRO identifies patients who are at risk for longer LOS following thoracoscopic lung cancer surgery. In addition to its utility for preoperative counseling and planning, these data may be useful in identifying patients who may benefit from risk-reduction measures.

Percutaneous Tracheostomy With Apnea During Coronavirus Disease 2019 Era: A Protocol and Brief Report of Cases.

OBJECTIVE: To assess feasibility of modified protocol during percutaneous tracheostomy in coronavirus disease 2019 pandemic era. DESIGN: A retrospective review of cohort who underwent percutaneous tracheostomy with modified protocol. SETTINGS: Medical, surgical, and neurologic ICUs. SUBJECTS: Patients admitted in medical, surgical, and neurologic units with prolonged need of mechanical ventilation or inability to liberate from the ventilator. INTERVENTIONS: A detailed protocol was written. Steps were defined to be performed before apnea and during apnea. A feasibility study of 28 patients was conducted. The key aerosol-generating portions of the procedure were performed with the ventilator switched to standby mode with the patient apneic. MEASUREMENTS AND MAIN RESULTS: Data including patient demographics, primary diagnosis, age, body mass index, and duration of apnea time during the tracheostomy were collected. Average ventilator standby time (apnea) during the procedure was 238 seconds (3.96 min) with range 149 seconds (2.48 min) to 340 seconds (5.66 min). Single-use (disposable) bronchoscopes (Ambu A/S [Ballerup, Denmark] or Glidescope [Verathon, Inc., Bothell, WA]) were used during all procedures except in nine. No desaturation events occurred during any procedure. CONCLUSIONS: Percutaneous tracheostomy performed with apnea protocol may help minimize aerosolization, reducing risk of exposure of coronavirus disease 2019 to staff. It can be safely performed with portable bronchoscopes to limit staff and minimize the surfaces requiring disinfection post procedure.
