Survival Benefit and Genetic Profile of Pemetrexed as Initial Chemotherapy in Selected Chinese Patients With Advanced Lung Adenocarcinoma.

This study investigated survival in selected Chinese patients with advanced lung adenocarcinoma who received initial chemotherapy with pemetrexed. We also explored the relationship between genetic biomarkers and pemetrexed efficacy. We retrospectively collected patients ( = 1,047) enrolled in the Chinese Patient Assistance Program from multiple centers who received pemetrexed alone or combined with platinum as initial chemotherapy and continued pemetrexed maintenance therapy for advanced lung adenocarcinoma from November 2014 to June 2017.

Propensity-Matched Analysis of Clinical Relevance of the Highest Mediastinal Lymph Node Metastasis.

Background: The clinical relevance of the highest mediastinal lymph node (HMLL) metastasis in patients with pathological N2 non-small cell lung cancer (NSCLC) is still controversial. Our study aimed to reassess the effect of HMLL metastasis on survival.

Methods: Patients with stage pT1-4N2M0 NSCLC who underwent major lung resection and systemic lymphadenectomy at Peking University People's Hospital from 2004 to 2015 were identified.

Identifying patients at higher risk of pneumonia after lung resection.

Background: Pneumonia is considered as one of the most common and serious complications after lung resection. The purpose of this study was to identify the risk factors associated with postoperative pneumonia (POP) after lung resection and to develop a scoring system to stratify patients with increased risk of POP.

Methods: A retrospective review of a prospective database of patients between September 2014 and June 2016 was carried out.

Diagnostic value of endobronchial ultrasound guided transbronchial needle aspiration in superior vena cava syndrome.

Background: The pathological diagnosis is of critical importance to the subsequent treatment for the pathients with superior vena cava syndrome (SVCS). The aim of this study is to report our experience in the diagnosis of SVCS by endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA).

Methods: The data of 520 patients who underwent EBUS-TBNA from September 2009 to May 2012 at our institution were reviewed.

Diagnostic value of endobronchial ultrasound-guided transbronchial needle aspiration in intrapulmonary lesions.

Background: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is considered to have high value in the staging of mediastinal lymph nodes in lung cancer. The current study was conducted to investigate the diagnostic value of EBUS-TBNA in intrapulmonary lesions located near the central airway.

Methods: From September 2009 to March 2013, 66 patients with pulmonary masses located close to the central airways suspected to be lung cancer were accessed by EBUS-TBNA.

[Application of endobronchial ultrasound-guided transbronchial needle aspiration in the diagnosis of isolated mediastinal lesions].

Objective: To evaluate the role of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in the diagnosis of isolated mediastinal lesions.

Methods: A retrospective study was conducted of 73 consecutive patients with isolated mediastinal lesions of unknown origin without parenchymal lung abnormalities, who underwent EBUS-TBNA from September 2009 to April 2011. The patients who were nondiagnostic with EBUS-TBNA subsequently underwent surgical biopsies and a minimum of 6 months'clinical and radiologic follow-up.

Application of endobronchial ultrasound-guided transbronchial needle aspiration in the diagnosis of mediastinal lesions.

Background: Mediastinal lesions are often difficult to diagnose in clinical practice because of the unique anatomical position of the mediastinum, which makes performance of biopsy difficult. The value of endobronchial ultrasound-guided transbronchial needle aspiration in the diagnosis of lung cancer and mediastinal lymph node staging has been widely accepted. However, few studies have been conducted on the value of endobronchial ultrasound-guided transbronchial needle aspiration in the diagnosis and differential diagnosis of mediastinal lesions.

[Establishment of a mathematical prediction model to evaluate the probability of malignancy or benign in patients with solitary pulmonary nodules].

Objective: To evaluate the clinical factors affecting the definite pathological diagnosis of solitary pulmonary nodules (SPN) with multivariate Logistic regression analysis, and to build the clinical prediction model to estimate the probability of malignancy.

Methods: A retrospective cohort study in our institution included 371 patients (197 males and 174 females) with definite pathological diagnosis of solitary pulmonary nodules from Jan 2000 to Sep 2009 (group A). Clinical data included age, gender, course of disease, symptoms, history and quantity of smoking history, history of tumor, family history of tumor, site, diameter, calcification, speculation, border, lobulation, traction of pleural, vascular convergence sign, and cavity.

Comparison of the autofluorescence bronchoscope and the white light bronchoscope in airway examination.

Background And Objective: The sensitivity and accuracy of white light bronchoscopy (WLB) in airway examination are low. Autofluorescence bronchoscope (AFB) can determine early lesions in bronchial mucosa more sensitively, but it has seldom performed in China. To assess the clinical value of the AFB in airway examination, we compared the sensitivity and specificity of the AFB and WLB in detecting cancer of the airway mucosa.
