[Impact of the COVID-19 pandemic on thoracic surgery training in Spain].

In the more than 2 years since its emergence, the SARS-CoV-2 pandemic has prompted important changes in healthcare systems and their organization. The aim of this study is to determine the implications in specialized thoracic surgery training as well as the repercussions on thoracic surgery residents. With this objective, the Spanish Society of Thoracic Surgery has conducted a survey among all its trainees and those who had finished their residency during the last 3 years.

Analysis of solitary pulmonary nodule after surgical resection in patients with 18F-FDG positron emission tomography integrated computed tomography in the preoperative work-up.

Introduction: To analyse clinicopathological characteristics of patients operated for pulmonary solitary nodule (PSN) and 18F-FDG integrated PET-CT scan after surgical resection.

Methodology: Retrospective study on a prospective database of patients operated from January 2007 to October 2017 for PSN without preoperative diagnosis. Dependent variable was anatomopathological result (benign vs malignant) of PSN.

Executive summary of the SEPAR recommendations for the diagnosis and treatment of non-small cell lung cancer.

The Thoracic Surgery and Thoracic Oncology groups of the Spanish Society of Pulmonology and Thoracic Surgery (SEPAR) have backed the publication of a handbook on recommendations for the diagnosis and treatment of non-small cell lung cancer. Due to the high incidence and mortality of this disease, the best scientific evidence must be constantly updated and made available for consultation by healthcare professionals. To draw up these recommendations, we called on a wide-ranging group of experts from the different specialties, who have prepared a comprehensive review, divided into 4 main sections.

(18)F-FDG-PET/CT in the assessment of pulmonary solitary nodules: comparison of different analysis methods and risk variables in the prediction of malignancy.

Objective: To compare the diagnostic performance of different metabolical, morphological and clinical criteria for correct presurgical classification of the solitary pulmonary nodule (SPN).

Methods: Fifty-five patients, with SPN were retrospectively analyzed. All patients underwent preoperative (18)F-fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed tomography (CT).

Heterogeneity in [¹⁸F]fluorodeoxyglucose positron emission tomography/computed tomography of non-small cell lung carcinoma and its relationship to metabolic parameters and pathologic staging.

To investigate the relationships between tumor heterogeneity, assessed by texture analysis of [18F]fluorodeoxyglucose-positron emission tomography (FDG-PET) images, metabolic parameters, and pathologic staging in patients with non-small cell lung carcinoma (NSCLC). A retrospective analysis of 38 patients with histologically confirmed NSCLC who underwent staging FDG-PET/computed tomography was performed. Tumor images were segmented using a standardized uptake value (SUV) cutoff of 2.

Video-Assisted Minithoracotomy Diaphragmatic Plication: Respiratory Effects in Adults.

 The objective of this study was to analyze the clinical respiratory and spirometric effects of video-assisted minithoracotomy diaphragmatic plication (VAM-T DP) in the treatment of diaphragmatic eventration.  A retrospective longitudinal study of 18 patients who underwent a VAM-T DP in our service between February 2005 and July 2011 was performed. Data of patient characteristics, preoperative clinical variables, and postoperative results (3, 6, and 12 months) were collected for statistical analysis using the software package SPSS 13.

Is video-assisted thoracoscopic diaphragmatic plication a widespread technique for diaphragmatic hernia in adults? Review of the literature and results of a national survey.

Diaphragmatic plication is the most accepted treatment for symptomatic diaphragmatic hernia in adults. The fact that this pathology is infrequent and this procedure not been widespread means that this is an exceptional technique in our field. To estimate its use in the literature, we carried out a review in English and Spanish, to which we added our series.

Analysis of Expression of Vascular Endothelial Growth Factor A and Hypoxia Inducible Factor-1alpha in Patients Operated on Stage I Non-Small-Cell Lung Cancer.

Objectives. Recent studies show that expression of hypoxia inducible factor-1alpha (HIF-1α) favours expression of vascular endothelial growth factor A (VEGF-A), and these biomarkers are linked to cellular proliferation, angiogenesis, and metastasis in different cancers. We analyze expression of HIF-1α and VEGF-A to clinicopathologic features and survival of patients operated on stage I non-small-cell lung cancer.

The Spanish Society of Pulmonology and Thoracic Surgery Lung Cancer Cooperative Group-II registry. A descriptive study.

Introduction And Objectives: The seventh edition of the TNM classification, together with undeniable advantages, has limitations. The International Association for the Study of Lung Cancer (IASLC) Staging Committee has designed an international prospective study to improve this classification. A group of thoracic surgeons and pulmonologists was established in the Spanish Society of Pulmonology and Thoracic Surgery (SEPAR) Oncology area, and created a registry of new lung cancer (LC) cases to participate in this project.

Technical aspects of the anterior transmanubrial approach in thoracic inlet tumor surgery.

Surgical treatment of thoracic inlet tumors represents a challenge to the surgeon due to its location and anatomical elements contained in that region. Several surgical approaches have been proposed, each of them showing some advantages but drawbacks as well. In our opinion, the anterior transmanubrial approach described in 1997 is one of the most convenient.

Prognostic influence of loss of blood group A antigen expression in pathologic stage I non-small-cell lung cancer.

Introduction: In the scientific literature, contradictory results has been published on the prognostic value of the loss of expression of blood group antigen A (BAA) in lung cancer. The objective of our study was to analyze this fact in our surgical series.

Patients And Methods: In a multicenter study, 402 non-small-cell lung cancer (NSCLC) patients were included.

Multicenter analysis of survival and prognostic factors in pathologic stage I non-small-cell lung cancer according to the new 2009 TNM classification.

Introduction: The new 2009 TNM classification introduced important modifications in lung cancer staging. The aim of this study is to validate our series of patients with pathologic stage I non-small-cell lung cancer according to the 7th edition of the TNM classification of malignant tumors and to the factors related with prognosis.

Patients And Methods: A multicenter retrospective study was performed.

[Diseases of the diaphragm].

The diaphragm is the main muscle involved in ventilation and is supplied exclusively by the phrenic nerves. Congenital defects of the diaphragm muscle or phrenic nerve injury cause diaphragmatic paralysis-eventration. Prognosis and treatment depend on whether involvement is unilateral or bilateral and on the patient's previous clinical status.

[Left postpneumonectomy syndrome: early endoscopic treatment].

Postpneumonectomy syndrome is characterized by postoperative bronchial obstruction caused by mediastinal shift. The syndrome is well documented in the medical literature as a late complication of right pneumonectomy; however, it rarely occurs following resection of the left lung, and only 10 cases have been published. The pathophysiology, clinical manifestations, prognosis, and treatment are similar for both sides of the lung.
