Can a children's hospital still cut it? Comparing outcomes of pediatric, adolescent and young adult patients undergoing thoracic surgery for lung metastases.

BACKGROUND: Adolescents and young adults (AYAs) with cancer have unique medical challenges compared with younger children and older adults. Dedicated centers have been established to deliver cancer therapy to the AYA population; many of these programs are located in pediatric hospitals. Outcomes of AYA patients on pediatric protocols are generally superior to those on adult protocols. Little is understood about the impact of care within a pediatric environment for surgical care of young adults. METHODS: A retrospective institutional review was performed of patients undergoing thoracic metastectomy between 2012 and 2017. Demographics, procedural factors, cost, and outcomes were analyzed. Patients were divided into two groups: > 18 and <18 years. RESULTS: Ninety-one procedures were performed: 61.5% (n = 56) were in patients <18 years old and 38.5% (n = 35) were > 18 years old. The median age was 6.5 years for <18 years old and 28 years for > 18 years old. Older patients had a significantly longer operative time on thoracoscopic cases; 91 versus 63 minutes. Fifty percent of the > 18 group had > 1 lesion resected compared with one lesion resected in 80.8% in <18 years old. No significant differences were found between the two groups in the duration of chest tube or length of stay. The AYA group demonstrated more "adult type" comorbidities. CONCLUSION: AYA patients have unique developmental and emotional challenges. Surgical intervention in this special population of patients cared for within a pediatric environment shows no significant difference in outcome compared with pediatric patients undergoing the same procedure. AYA patients with "adult type" comorbidities can safely undergo multidisciplinary care including surgery within a pediatric environment without the need to fragment care.

Treatment outcome of chest wall soft tissue sarcomas: Analysis of prognostic factors.

BACKGROUND: Primary soft tissue sarcomas (STSs) involving the chest wall are uncommon. The aim of this study was to identify factors that influence the prognosis of patients with primary chest wall STS. METHODS: The records of 38 patients (23 men and 15 women) who were treated at our institutions during 2002 to 2018 were reviewed. The following variables were evaluated as potential prognostic factors: sex, tumor size, chemotherapy, and completeness of surgical margins. Multivariate analysis was conducted to identify predictors of overall survival (OS) and disease-free survival (DFS). RESULTS: Of the 38 included patients, 5 had low-grade tumors and 33 had high-grade tumors. Five patients required chest wall reconstruction including rib resection. Thirty patients (79%) underwent R0 resection. The 5-year OS and DFS rates were 45% and 27%, respectively. Local recurrence developed in 7 patients. Multivariate analysis identified tumor size (hazard ratio [HR]: 4.13; 95% confidence interval [CI]: 1.05-16.24; P = .04) and R1/2 resection (HR: 3.92; 95% CI: 1.12-13.66; P = .03) as predictors of OS. CONCLUSIONS: Prognostic factors for survival included tumor size and completeness of surgical margins. Complete tumor excision is desirable, particularly in cases of early detection.

The maximum dimension of the inferior vena cava is a significant predictor of postoperative mortality in lung cancer patients with idiopathic interstitial pneumonia.

PURPOSE: Several vascular measurements in computed tomography (CT) were reported to be indicators of pulmonary hypertension in chronic obstructive pulmonary disease (COPD) patients. We evaluated the usefulness of these parameters as predictors of postoperative mortality in lung cancer patients with IIP. METHODS: This retrospective study was performed on 1888 patients. The following CT findings were evaluated: diameter of the main pulmonary artery, ascending aorta, and the short axis of the inferior vena cava (IVC). Univariate and multivariate analyses were conducted to determine predictors of surgical mortality. RESULTS: In the IIP patients, the 90-day mortality was 0.8%, and the 2-year mortality was 5.8%. Regarding the 90-day mortality in patients with IIP, a multivariate analysis revealed a short axis of IVC > 21 mm [odds ratio (OR) 6.4, p < 0.01) and the risk score reported by Japanese Association for Chest Surgery (JACS) (OR 1.4, p = 0.01) as independent predictors. Regarding the 2-year mortality in patients with IIP, a multivariate analysis revealed IVC > 21 mm (OR 2.3, p < 0.04), %VC < 80% (OR 2.4, p = 0.02), and pathological cancer stages II and III vs. I (OR 7.2, p < 0.001) as independent predictors. CONCLUSIONS: Enlargement of the IVC as measured by CT was a significant predictor of mortality after surgery for lung cancer with IIP patients.

[Intensive therapy in thoracoabdominal surgery]. / Intensivnaia terapiia v torakoabdominal'noi khirurgii.

Since the creation of the intensive care unit, active scientific work has been carried out. Pre- and postoperative management of patients undergoing thoracoabdominal surgery was one of the main directions of this work. Diagnostic approaches, preventive measures and standards of treating patients after thoracoabdominal surgery have been developed. The results of this work allowed to reduce significantly contraindications for surgical interventions in these patients, to perform radical operations in patients with severe concomitant diseases, to reduce the incidence of postoperative complications and mortality.

Predictors of survival after resection of primary sarcomas of the chest wall-A large, single-institution series.

BACKGROUND AND OBJECTIVES: Chest wall sarcomas are rare and may demonstrate heterogeneous features. Surgery remains the mainstay of treatment with chemotherapy and radiotherapy used as adjuncts. Herein, we report outcomes of a large cohort of patients with primary chest wall sarcoma who underwent resection. METHODS: Records of 121 patients who underwent resection for primary chest wall sarcoma between 1998 and 2013 were reviewed. A thoracic pathologist reexamined all tumors and categorized them according to grade. Univariable and multivariable Cox analyses were conducted to identify predictors of overall survival (OS). RESULTS: The median age was 45.0 (range, 11-81) years, and most tumors (63.6%, 77) were high grade. The median tumor size was 7 cm (range, 1-21 cm). Fifty-nine (48.8%) patients received neoadjuvant chemotherapy and 12 (9.9%) received neoadjuvant radiotherapy. A complete resection was achieved in 103 (85.1%) patients. Neoadjuvant chemotherapy (P = 0.532) and radiation ( P = 1.000) were not associated with a complete resection. Five-year OS among patients undergoing R0 and R1 resections was 61.9% and 27.8%, respectively. Multivariable analysis identified high grade (HR, 15.21; CI, 3.57-64.87; P < 0.001), R1 (HR, 3.10; CI, 1.40-6.86; P = 0.005), R2 resection (HR, 5.18; CI, 1.91-14.01; P = 0.001), and age (HR, 1.02; CI, 1.01-1.03; P = 0.002) as predictors of OS. CONCLUSIONS: In this series of resected chest wall sarcomas, complete resection and tumor grade remain the most important survival predictors. Individual decisions are required for the utilization of neoadjuvant therapy.

Initial experience of robot-assisted Ivor-Lewis esophagectomy: 61 consecutive cases from a single Chinese institution.

This study aims to report the technical details and preliminary outcomes of robot-assisted Ivor-Lewis esophagectomy (RAILE) using two different types of intrathoracic anastomosis from a single institution in China. From May 2015 to October 2017, 61 patients diagnosed with mid-lower esophageal cancer were treated with RAILE. The RAILE procedure was performed in two stages. The first 35 patients underwent circular end-to-end stapled intrathoracic anastomosis (stapled group), and the remaining 26 patients had a double-layered, completely hand-sewn intrathoracic anastomosis (hand-sewn group). Patient characteristics, surgical techniques, postoperative complications, and pathology outcomes were analyzed. The mean operating time and mean blood loss were 315.6 ± 59.4 minutes and 189.3 ± 95.8 mL, respectively. There was one patient who underwent conversion to thoracotomy. The 30-day and in-hospital mortality rates were 0%. Overall complications were observed in 22 patients (36.1%) according to the Clavien-Dindo (CD) and the Esophagectomy Complications Consensus Group (ECCG) classifications, of whom 6 patients (9.8%) had anastomotic leakage (ECCG, Type II). The median length of hospitalization (LOH) was 10 days (IQR, 5 days). Complete (R0) resection was achieved in all cases. The mean tumor size was 3.2 ± 1.5 cm, and the mean number of totally dissected lymph nodes was 19.3 ± 9.2. Regarding the operative outcomes between stapled and hand-sewn groups, there were no significant differences in the operative time (325.4 ± 66.6 vs. 302.3 ± 45.9 min, P = 0.114), blood loss (172.9 ± 74.1 vs. 211.5 ± 117.0 mL, P = 0.147), conversion rate (2.9 vs. 0%, P = 1.000), overall complication rate (37.1 vs. 34.6%, P = 0.839) or LOH (10 vs. 9.5 days, P = 0.415). RAILE using both stapled and hand-sewn intrathoracic anastomosis is safe and technically feasible with satisfactory perioperative outcomes for the treatment of mid-lower thoracic esophageal cancer.

Role of postoperative radiotherapy in the management of malignant pleural mesothelioma : A propensity score matching of the SEER database.

INTRODUCTION: This study assessed the prognostic impact of postoperative radiotherapy in patients with surgically resected malignant pleural mesothelioma (MPM). METHODS: MPM patients diagnosed between 2000 and 2013 were identified from the SEER (Surveillance, Epidemiology, and End Results) database. A propensity-matched analysis was performed considering baseline characteristics (age, gender, race, histology, TNM stage, and type of surgery). RESULTS: A total of 2166 patients were identified. The median age was 60 years (range 25-85 years), and 469 patients received postoperative radiotherapy. Both before and after propensity score matching, overall survival (P < 0.0001 and P = 0.012, respectively) was better in the postoperative radiotherapy group. When the overall survival was stratified by histology, postoperative radiotherapy did not improve the survival in sarcomatoid histology patients both before and after matching (P = 0.424 and P = 0.281, respectively). In multivariate analysis of the matched population, not receiving postoperative radiotherapy did not correlate with worse survival (hazard ratio: 1.175; P = 0.12). Factors associated with worse survival include sarcomatoid histology, nodal positivity, and age ≥70. CONCLUSION: Evidence from this analysis is insufficient on its own to routinely recommend postoperative radiotherapy for surgically resected MPM. However, large-scale prospective clinical trials are warranted to further evaluate this intervention in nonsarcomatoid histology.

When Is the Optimal Timing of the Surgical Treatment for Secondary Spontaneous Pneumothorax?

Objectives The definition of spontaneous pneumothorax is accumulation of air in the pleural space, resulting in dyspnea or chest pain. Unlike primary spontaneous pneumothorax, secondary pneumothorax can be a life-threatening condition and spontaneous healing rate is uncommon. Although surgery is the most effective treatment modality for pneumothorax, surgical management and timing is difficult where there is underlying lung disease and/or medical comorbidities. Prolonged air leakage increases the morbidity and mortality in thoracic surgery. We hypothesized that duration of air leakage before operation may lead to increase in complications. Methods This study is a retrospective review of 155 consecutive patients with air leakage who underwent bullectomy for secondary spontaneous pneumothorax from January 2005 to July 2013. The patients were divided according to the duration of preoperative air leakage. The patients were followed-up until the time of last visit or death. Postoperative morbidity and mortality were assessed and the risk factors for complications were analyzed. Results The median age was 65 years (range, 52-88) with male predominance (96.13%). The median duration of preoperative air leakage was 6 days (range, 1-30). The median surgery time was 90 minutes (range, 25-300) and median hospital stay after operation was 7 days (range, 3-75). Postoperative complications occurred in 38 patients (24.52%) and postoperative recurrence was shown to have occurred in 8 patients (5.16%). With multivariate analysis, risk factors for postoperative complications were: underlying interstitial lung disease and air leakage > 5 days before operation. Conclusion Persistent air leakage was a major surgical indication for pneumothorax. Early surgical treatment reduced postoperative complications for secondary spontaneous pneumothorax.

How to define the therapeutic limits.

With the advance of technological progress and the increase in life expectancy, it is nowadays mandatory to define what is the therapeutic limit. Every day each physician must take therapeutic decisions on the basis of his scientific knowledge, but also of his own conscience and sense of limits. They can not avoid to consider the global risk of death, disability and morbidity in more advanced age, especially in the field of cardiology and cardiac surgery. In these subjects, both fit that frail, is necessary not only an evaluation for adequate risk assessment, but also a multidimensional assessment performed with advanced tools. The resilience of the subject, ability for which some patients considered out of therapy demonstrate the ability to adapt and overcome critical phases, must also be weighed. Where and what is the therapeutic limit should be evaluated individually with humility, competence and capacity for dialogue with other disciplines in a work team that respects the individual professionalism. In recent years, much has changed in the cardiology/cardiac surgery approach in old people. With the development of less or minimal invasive new techniques, there are no more insurmountable limits that can be connected only to the chronological age of the patients.

Goals of surgery and assessment tools for elderly patients referred for cardiac and noncardiac surgery.

Surgery in elderly patients is associated with the risk of death, complications, functional decline and disability. Prior to surgery, therefore, an assessment of the health-related priorities, a realistic evaluation of the surgical risks, and individualized optimization of the procedural pathway to follow are mandatory.

Readmission destination and risk of mortality after major surgery: an observational cohort study.

BACKGROUND: Hospital readmissions are common after major surgery, although it is unknown whether patients achieve improved outcomes when they are readmitted to, and receive care at, the index hospital where their surgical procedure was done. We examined the association between readmission destination and mortality risk in the USA in Medicare beneficiaries after a range of common operations. METHODS: By use of claims data from Medicare beneficiaries in the USA between Jan 1, 2001, and Nov 15, 2011, we assessed patients who needed hospital readmission within 30 days after open abdominal aortic aneurysm repair, infrainguinal arterial bypass, aortobifemoral bypass, coronary artery bypass surgery, oesophagectomy, colectomy, pancreatectomy, cholecystectomy, ventral hernia repair, craniotomy, hip replacement, or knee replacement. We used logistic regression models incorporating inverse probability weighting and instrumental variable analysis to measure associations between readmission destination (index vs non-index hospital) and risk of 90 day mortality for patients who underwent surgery who needed hospital readmission. FINDINGS: 9,440,503 patients underwent one of 12 major operations, and the number of patients readmitted or transferred back to the index hospital where their operation was done varied from 186,336 (65·8%) of 283,131 patients who were readmitted after coronary artery bypass grafting, to 142,142 (83·2%) of 170,789 patients who were readmitted after colectomy. Readmission was more likely to be to the index hospital than to a non-index hospital if the readmission was for a surgical complication (189,384 [23%] of 834,070 patients readmitted to index hospital vs 36,792 [13%] of 276,976 patients readmitted non-index hospital, p<0·0001). Readmission to the index hospital was associated with a 26% lower risk of 90 day mortality than was readmission to a non-index hospital, with inverse probability weighting used to control for selection bias (odds ratio [OR] 0·74, 95% CI 0·66-0·83). This effect was significant (p<0·0001) for all procedures in inverse probability-weighted models, and was largest for patients who were readmitted after pancreatectomy (OR 0·56, 95% CI 0·45-0·69) and aortobifemoral bypass (OR 0·69, 95% CI 0·61-0·77). By use of hospital-level variation among regional index hospital readmission rates as an instrument, instrumental variable analysis showed that the patients with the highest probability of returning to the index hospital had 8% lower risk of mortality (OR 0·92 95% CI 0·91-0·94) than did patients who were less likely to be readmitted to the index hospital. INTERPRETATION: In the USA, patients who are readmitted to hospital after various major operations consistently achieve improved survival if they return to the hospital where their surgery took place. These findings might have important implications for cost-effectiveness-driven regional centralisation of surgical care. FUNDING: None.

Cardiovascular disease in Europe--epidemiological update 2015.

This article provides an update for 2015 on the burden of cardiovascular disease (CVD), with a particular focus on coronary heart disease (CHD) and stroke, across the countries of Europe. Cardiovascular disease is still the most common cause of death within Europe, causing almost two times as many deaths as cancer across the continent. Although there is clear evidence, where data are available, that mortality from CHD and stroke has decreased substantially over the last 5-10 years, there are still large inequalities found between European countries, in both current rates of death and the rate at which these decreases have occurred. Similarly, rates of treatment, particularly surgical intervention, differ widely between those countries for which data are available, indicating a range of inequalities between them. This is also the first time in the series that we use the 2013 European Standard Population (ESP) to calculate age-standardized death rates (ASDRs). This new standard results in ASDRs around two times as large as the 1976 ESP for CVD conditions such as CHD but changes little the relative rankings of countries according to ASDR.

Finding the evidence for pulmonary metastasectomy in colorectal cancer: the PulMicc trial.

The PulMiCC trial is a randomized controlled trial testing the effect on survival of pulmonary metastasectomy in patients with colorectal cancer. In stage 1 of the trial patients with treated primary colorectal cancer metastatic to the lungs are invited to consent for protocol-based evaluation of their suitability for metastasectomy. The evaluation is as in current practice and includes PET/CT. A decision for or against metastasectomy may be based on the opinion of the clinicians and the preference of the patient. If there is uncertainty the patient is invited to consent to have the treatment arm assigned by randomization in stage 2 of PulMiCC. More than 300 patients have entered stage 1 and more than 70 are in stage 2.

Benchmarking clinical practice in surgery: looking beyond traditional mortality rates.

This paper proposes two new measures to assess performance of surgical practice based on observed mortality: reliability, measured as the area under the ROC curve and a living score, the sum of individual risk among surviving patients, divided by the total number of patients. A Monte Carlo simulation of surgeons' practice was used for conceptual validation and an analysis of a real-world hospital department was used for managerial validation. We modelled surgical practice as a bivariate distribution function of risk and final state. We sampled 250 distributions, varying the maximum risk each surgeon faced, the distribution of risk among dead patients, the mortality rate and the number of surgeries performed yearly. We applied the measures developed to a Portuguese cardiothoracic department. We found that the joint use of the reliability and living score measures overcomes the limitations of risk adjusted mortality rates, as it enables a different valuation of deaths, according to their risk levels. Reliability favours surgeons with casualties, predominantly, in high values of risk and penalizes surgeons with deaths in relatively low levels of risk. The living score is positively influenced by the maximum risk for which a surgeon yields surviving patients. These measures enable a deeper understanding of surgical practice and, as risk adjusted mortality rates, they rely only on mortality and risk scores data. The case study revealed that the performance of the department analysed could be improved with enhanced policies of risk management, involving the assignment of surgeries based on surgeon's reliability and living score.

Clinical impact of the new IASLC/ATS/ERS lung adenocarcinoma classification for chest surgeons.

In 2011, a new pathological classification of lung adenocarcinoma was proposed by the International Association for the Study of Lung Cancer, the American Thoracic Society and the European Respiratory Society. The new criteria classify adenocarcinomas into eight subtypes according to their histological features. The criteria introduce a new concept of early stage lung cancer, consisting of adenocarcinoma in situ and minimally invasive adenocarcinoma, and categorize invasive adenocarcinomas by the predominant histological pattern. In addition to morphological differences among subtypes, the classification also considers the tumor behavior based on the genetic background within each subtype. We herein review the clinical impact of this new classification for chest surgeons based on the data from several recent validation studies from various institutions.

A Validation Study for POSSUM and EuroSCORE as a Predictor of Mortality After Selective Cardiac Surgery.

AIM: to assess physiological and operative severity score for the enumeration of mortality (POSSUM) scoring system and compare it with European system for cardiac operative risk evaluation (EuroSCORE) scores in patients who underwent cardiac surgery from two hospitals in the southwestern region of Iran. METHODS: in this retrospective study, total of all 1420 patients who were admitted for elective cardiac surgery at our centers, from 2007 to 2012, were scored using the POSSUM and EuroSCORE systems. RESULTS: the overall mortality rate was 0.87%. Among the risk factors, history of diabetes, smoking, respiratory disease, and myocardial infarction, were significantly affect the mortality rate. Therefore, of these risk factors, only the hemoglobin was significantly correlated with the morbidity rate. The predictive accuracy of mortality equations was 74.5%. The lower predictive accuracy of mortality equations was 67.8% was observed using EuroSCORE. CONCLUSION: although results are statistically significant, but the analysis have never intended to affect the decision to operate, and this decision must be based on clinical expertise, because of the need to standardize data collection and stratify the risks involved in operations, scoring systems such as POSSUM should be used prospectively. However, if analyzed correctly, POSSUM is a good predictor of mortality in patients undergoing cardiac surgery.

[Diagnostics and treatment of congenital malformations of the lung and mediastinum in newborn children and infants].

The article presents the experience of treatment of newborn children and infants with congenital malformations of the lung and mediastinum, which required a surgery. Children (138 cases) were treated during recent 18 years. There was a prevalence of full-term infants (73%). Fetal malformations were diagnosed in prenatal period in majority of cases. Computed tomography was the main method of diagnostics after delivery. Children (110 cases) were operated out of 138. Children with extrapulmonary sequestration didn't undergo surgery in case of absence of clinical manifestations. The authors made a conclusion that malformations of the lung and mediastinum should be included in number of differentiated diseases in case of respiratory distress syndrome in newborn children. The indications to early surgery should be the danger of contamination and malignant transformation, presence of intrathoracic tension syndrome in neonatal period.

Does EuroSCORE II perform better than its original versions? A multicentre validation study.

AIMS: The European system for cardiac operation risk evaluation (EuroSCORE) is widely used for predicting in-hospital mortality after cardiac surgery. A new score (EuroSCORE II) has been recently developed to update the previously released versions. This study was undertaken to validate EuroSCORE II, to compare its performance with the original EuroSCOREs and to evaluate the effects of the removal of those factors that were included in the score even if they were statistically non-significant. METHODS AND RESULTS: Data on 12,325 consecutive patients who underwent major cardiac surgery in a 6-year period were retrieved from three prospective institutional databases. Discriminatory power was assessed using the c-index and comparison among the scores' performances was performed with Delong, bootstrap, and Venkatraman methods. Calibration was evaluated with calibration curves and associated statistics. The in-hospital mortality rate was 2.2%. The discriminatory power was high and similar in all algorithms (area under the curve 0.82, 95% CI: 0.79-0.84 for additive EuroSCORE; 0.82, 95% CI: 0.79-0.84 for logistic EuroSCORE; 0.82, 95% CI: 0.80-0.85 for EuroSCORE II). The EuroSCORE II had a fair calibration till 30%-predicted values and over-predicted beyond. The removal of non-significant factors from EuroSCORE II did not affect performance, being both the calibration and discrimination comparable. CONCLUSION: This validation study demonstrated that EuroSCORE II is a good predictor of perioperative mortality. It showed an optimal calibration until 30%-predicted mortality. Nonetheless, it does not seem to significantly improve the performance of older versions in the higher tertiles of risk. Moreover, it could be simplified, as the removal from the algorithm of non-significant factors does not alter its performance.

Predictive factors of supraventricular arrhythmias after noncardiac thoracic surgery: a multicenter study.

BACKGROUND: Supraventricular cardiac arrhythmias are the most common rhythm disturbances in patients following thoracic surgery. The purpose of our study was to determine which of the clinical parameters are the most valuable in predicting postoperative atrial fibrillation (AF) after lung surgery. METHODS: Retrospective analysis was carried out on 987 patients after noncardiac thoracic surgery to define the prevalence, associated risk factors, and clinical course of postoperative arrhythmias. There were 822 men and 165 women, age 34 to 78 years (mean age: 61 ± 8 years). The patients were divided into two groups depending on the occurrence or absence of supraventricular arrhythmia. Group I consisted of 876 patients who were free from rhythm disturbances. The remaining 111 patients exhibited episodes of supraventricular arrhythmia (29 supraventricular tachycardia; 82 AF). These 111 patients were placed in Group II. Preoperative, operative, and postoperative data were reviewed. Statistical analysis was performed. RESULTS: A statistically significant difference was found between the two groups in age, previous history of heart disease, and lung resection, especially pneumonectomy. CONCLUSION: Age, history of prior heart disease, lung resection, and the extent of pulmonary resection are the main risk factors for postoperative supraventricular arrhythmia in patients undergoing major thoracic operations.
