Video-assisted thoracoscopic surgery resection and reconstruction of thoracic trachea in the management of a tracheal neoplasm.

Intratracheal tumor is a rare tumor, accounting for only 2% of upper respiratory tract neoplasms. Its symptoms are similar to those of head and neck cancers, including coughing up blood, sore throat, and airway obstruction. The diagnosis of this disease is often based on the findings of fibrobronchoscopy or computed tomography (CT).

Non-intubated resection and reconstruction of trachea for the treatment of a mass in the upper trachea.

Tumors of the upper trachea are typically treated by tracheal resection and reconstruction via neck incision under general anesthesia. In recent years, non-intubated thoracic surgery has been widely applied for the treatment of lung diseases due to its advantages including quick postoperative recovery. In this article, we describe the application of non-intubated tracheal resection and reconstruction in one patient for the treatment of a mass in upper trachea.

Non-intubated combined with video-assisted thoracoscopic in carinal reconstruction.

Carinal reconstruction is a difficult technique combined with video-assisted thoracoscopic surgery (VATS). It has a high requirement on the operator's skills in operating thoracoscope and meanwhile requires the close cooperation from anesthesiologists. Tracheal intubation and ventilator-assisted ventilation are key steps to ensure the success of surgery.

Video-assisted transthoracic surgery resection of a tracheal mass and reconstruction of trachea under non-intubated anesthesia with spontaneous breathing.

Radical surgery for tracheal tumors is typically completed under basal anesthesia. Thus, endotracheal intubation and mechanical ventilation are required. However, these procedures may influence the surgical operation and meanwhile prolong the surgical duration and postoperative recovery.

Video-assisted thoracoscopic bronchoplasty/pulmonary arterial angioplasty.

Thoracoscopic bronchoplasty combined with pulmonary arterial angioplasty can be particularly challenging. In the past, it was often done by using a conventional incision or hybrid video-assisted small incision. In recent years, anecdotal articles have described the application of thoracoscopic bronchoplasty/pulmonary arterial angioplasty.

Video-assisted thoracoscopic surgery segmentectomy by non-intubated or intubated anesthesia: a comparative analysis of short-term outcome.

Background: The aim of this study was to reveal the short-term outcomes of video-assisted thoracoscopic surgery (VATS) segmentectomy without tracheal intubation compared with intubated general anesthesia with one-lung ventilation (OLV).

Methods: We performed a retrospective review of our institutional database of consecutive 140 patients undergoing VATS anatomical segmentectomy from July 2011 to June 2015. Among them, 48 patients were treated without tracheal intubation using a combination of thoracic epidural anesthesia (TEA), intrathoracic vagal blockade, and sedation (non-intubated group).

The prognosis after contraindicated surgery of NSCLC patients with malignant pleural effusion (M1a) may be better than expected.

Although non-small cell lung cancer (NSCLC) with malignant pleural effusion (M1a) is generally contraindicated for surgery, several reports have demonstrated favorable prognosis. This study aimed to describe the results of surgical intervention in this disease. In this retrospective study, we evaluated NSCLC patients with ipsilateral malignant pleural effusion selected from Surveillance Epidemiology and End-Results database (SEER).

Plasma level of advanced oxidation protein products as a novel biomarker of acute lung injury following cardiac surgery.

This study was designed to test the hypothesis that whether the plasma level of advanced oxidant protein products (AOPPs) would be useful for the clinical diagnosis of acute lung injury (ALI) following cardiac surgery with the technique of cardiopulmonary bypass (CPB). In this prospective study, seventy consecutive adults undergoing open heart surgery with CPB were included and assigned into the ALI (n = 18) and non-ALI (n = 52) groups according to the American-European Consensus Criteria. Plasma concentrations of AOPPs were measured at baseline, postoperative 1 h, 12 h, 24 h, and 48 h.

Analysis of ultra-deep targeted sequencing reveals mutation burden is associated with gender and clinical outcome in lung adenocarcinoma.

Gender-associated difference in incidence and clinical outcomes of lung cancer have been established, but the biological mechanisms underlying these gender-associated differences are less studied. Recently we have characterized the genomic landscape of lung adenocarcinoma derived from Chinese population (Reference [1]). In this study we evaluated the clinical significance of mutation burden in lung adenocarcinoma and found that the male tumors harbored statistically greater burden of genetic alterations than female counterparts (Male median 3 (range 0-34) vs female median = 2 (0-24), male to female ratio = 1.

Compound Library Screening Identified Cardiac Glycoside Digitoxin as an Effective Growth Inhibitor of Gefitinib-Resistant Non-Small Cell Lung Cancer via Downregulation of α-Tubulin and Inhibition of Microtubule Formation.

Non-small-cell lung cancer (NSCLC) dominates over 85% of all lung cancer cases. Epidermal growth factor receptor (EGFR) activating mutation is a common situation in NSCLC. In the clinic, molecular-targeting with Gefitinib as a tyrosine kinase inhibitor (TKI) for EGFR downstream signaling is initially effective.

Surgical treatment for primary pulmonary lymphoepithelioma-like carcinoma.

Objectives: Primary pulmonary lymphoepithelioma-like carcinoma (LELC) is a rare but unique subtype of non-small-cell lung cancer (NSCLC). Our study aimed to evaluate clinicopathological characteristics and the value of surgical treatment for LELC and explore the relevant prognostic factors in a relatively large cohort.

Methods: We retrospectively reviewed the medical records of 39 lung LELC patients who underwent pulmonary resection with curative intent between January 2009 and December 2013.

Chromosome 15q25 (CHRNA3-CHRNB4) Variation Indirectly Impacts Lung Cancer Risk in Chinese Males.

Introduction: Recently, genome-wide association studies (GWAS) in Caucasian populations have identified an association between single nucleotide polymorphisms (SNPs) in the CHRNA5-A3-B4 nicotinic acetylcholine receptor subunit gene cluster on chromosome 15q25, lung cancer risk and smoking behaviors. However, these SNPs are rare in Asians, and there is currently no consensus on whether SNPs in CHRNA5-A3-B4 have a direct or indirect carcinogenic effect through smoking behaviors on lung cancer risk. Though some studies confirmed rs6495308 polymorphisms to be associated with smoking behaviors and lung cancer, no research was conducted in China.

A targeted next-generation sequencing method for identifying clinically relevant mutation profiles in lung adenocarcinoma.

Molecular profiling of lung cancer has become essential for prediction of an individual's response to targeted therapies. Next-generation sequencing (NGS) is a promising technique for routine diagnostics, but has not been sufficiently evaluated in terms of feasibility, reliability, cost and capacity with routine diagnostic formalin-fixed, paraffin-embedded (FFPE) materials. Here, we report the validation and application of a test based on Ion Proton technology for the rapid characterisation of single nucleotide variations (SNVs), short insertions and deletions (InDels), copy number variations (CNVs), and gene rearrangements in 145 genes with FFPE clinical specimens.

The prevalence and clinicopathological features of programmed death-ligand 1 (PD-L1) expression: a pooled analysis of literatures.

Background & Aims: Programmed death-ligand 1 (PD-L1) has been recognized as a critical and promising target in therapies that direct immune escape of cancers. However, its association with aggressive clinicopathological features in solid tumors remains unclear. We investigated this question by synthesizing published articles.

Repulsive guidance molecule B inhibits metastasis and is associated with decreased mortality in non-small cell lung cancer.

Repulsive guidance molecules (RGMs) are co-receptors of bone morphogenetic proteins (BMPs) and programmed death ligand 2 (PD-L2), and might be involved in lung and other cancers. We evaluated repulsive guidance molecule B (RGMB) expression in 165 non-small cell lung cancer (NSCLC) tumors and 22 normal lung tissue samples, and validated the results in an independent series of 131 samples. RGMB was downregulated in NSCLC (P ≤ 0.

Video-assisted thoracoscopic surgery tracheal resection and carinal reconstruction for tracheal adenoid cystic carcinoma.

We report a case of video-assisted thoracoscopic surgery (VATS) tracheal resection and carinal reconstruction in a patient with tracheal tumor. The patient presented with adenoid cystic carcinoma (ACC) of the distal trachea, extending along the right main bronchus with carinal invasion. The reconstruction procedure was assisted with cross-field ventilation.

Metastatic EML4-ALK fusion detected by circulating DNA genotyping in an EGFR-mutated NSCLC patient and successful management by adding ALK inhibitors: a case report.

Background: Rebiopsy is highly recommended to identify the mechanism of acquired resistance to EGFR-TKIs in advanced lung cancer. Recent advances in multiplex genotyping based on circulating tumor DNA (ctDNA) provide a strong and non-invasive alternative for detection of the resistance mechanism.

Case Presentation: Here we report a multiple metastatic NSCLC patient who was detected to have pure EGFR 19 exon deletion (negative for EML4-ALK and ROS1 in both IHC-based and sequencing assay) in the primary lesion and responded to first-line and second-line EGFR-TKI treatments (erlotinib then HY-15772).

Improving Selection Criteria for ALK Inhibitor Therapy in Non-Small Cell Lung Cancer: A Pooled-Data Analysis on Diagnostic Operating Characteristics of Immunohistochemistry.

Lung cancer is often diagnosed by molecular markers for prediction and treatment. To date, the golden standard for detection of anaplastic lymphoma kinase (ALK) rearrangements is fluorescence in situ hybridization (FISH). We performed a pooled-data analysis on the diagnostic operating characteristics of immunohistochemistry (IHC) assay on non-small cell lung cancer (NSCLC).

Short-Term Outcome of Three-Dimensional Versus Two-Dimensional Video-Assisted Thoracic Surgery for Benign Pulmonary Diseases.

Background: It is unclear whether three-dimensional (3D) video-assisted thoracic surgery (VATS) pulmonary resections are comparable to two-dimensional (2D) VATS pulmonary resections in patients with potentially operable benign pulmonary diseases.

Methods: We analyzed the clinical data of patients who underwent 2D and 3D VATS pulmonary resections for benign diseases in our hospital from November 2013 to August 2014. Perioperative factors (estimated blood loss and operative time) and postoperative factors (postoperative hospital length of stay, postoperative complications, and duration of chest tube drainage) were evaluated.

Radical resection of right upper lung cancer using uniportal video-assisted thoracic surgery with non-intubated anesthesia.

Background: Presently, the clinical effect of radical video-assisted thoracic surgery (VATS) is equal to that of traditional open chest surgery and has received worldwide recognition of its advantages: less trauma and faster recovery. In the attempt to further the advancement of minimally invasive surgery the operative techniques of uniportal VATS and non-intubated anesthesia have been developed. These techniques have been widely applied in hospitals around the world, however there are few reports on the combined use of these techniques: non-intubated uniportal VATS.
