Active clinical trials for "Lung Neoplasms"

EBUS-TBNA is often the sole diagnostic test applied in patients with stage IV lung cancer. A limitation of the TBNA needle when using a 22 Gauge needle is the limited ability to procure adequate histological samples. Although a larger 19 Ga needle can procure histological samples as demonstrated by the conventional 19 Ga needle, published data are not existing with respect to molecular diagnostics. A new nitinol-based 19 Ga needle has been developed for EBUS-TBNA. Given the frequent usage of 22 Ga needles for molecular diagnostics and the recent technical advancements in 19 Ga needle technology, we conduct a RCT to compare the performance of both needle types.

This is a multicentre, non-interventional, prospective study to be carried out in representative oncology departments / institutions in order to determine the prevalence of EGFR mutations in treatment-naive Russian patients with cytologically verified advanced NSCLC in Russia.

EBUS elastography is a method to determine stiffness of lymph nodes, based on the minute deformation of the node by the beating heart. Whether EBUS elastography may further increase the sensitivity to predict the presence or absence of malignancy is unclear. We suggest to use EBUS elastography strain pattern analysis for this assessment and correlate these measurements with the final pathology outcome to determine NPV, PPV, sensitivity and specificity of this analysis to predict the presence or absence of malignancy in patients with (suspected) lung cancer in a prospectively obtained observational cohort study.

schema : Prospective prognostic study The main objective is to study the value of the Comprehensive Geriatric Assessment in predicting the risk of post operative complications after lung resection for cancer.

To evaluate the clinical benefit of spectrum analysis of endobronchial ultrasound images of lymph nodes during EBUS TBNA for lymph node staging in patients with lung cancer.

In the diagnosis of lung cancer, the cytological sample obtained during Bronchoscopy (FBS), has an increasingly important role in the characterization of malignancy. The cytological sample can be harvested during bronchoscopy by bronchial brushing, bronchial lavages or fine needle aspiration. Immunocytochemical staining allows not only to discriminate between small cell lung cancer versus non-small cell lung cancer (NSCLC), but also to identify the expression of specific markers such as TTF-1, CK7, CK20, 4A4, 34βE12 and p63. Thin Prep is a technique for cytological assay already validated and largely used in the immunocytochemical determination of gynaecologic specimens. Further Studies are required to asses the accuracy of this technique compared to conventional smear in cytological airway samples obtained by fine needle aspiration.

Purpose: To evaluate the performance of Extracellular Monitoring of Metabolic Activity Profiles of Peripheral Blood Mononuclear Cells (PBMC) analysis method in identifying lung cancer. The study population will include a total of 950 participants, patients with lung cancer before any treatment, and healthy and COPD patients as a control group.

The goal is to improve the efficiency of the diagnostic follow-up of patients with indeterminate pulmonary nodules by determining whether biomarkers for lung cancer diagnosis that are measured in minimally invasive biospecimens are able to distinguish malignant from benign pulmonary nodules that are incidentally detected in high-risk smokers.

Lung cancer is one of the leading causes of cancer-related death in Taiwan. Early diagnosis of lung cancer may improve cancer survival. Low-dose computed tomography (LDCT) was thought to be the best screening tool for lung cancer. However, there is growing concerns about radiation exposure, high cost, and high rate of false-positive screening result. Epidemiology data for LDCT screening in Taiwan is lacking. National Taiwan University Hospital Chu-Tung Branch (NTUHCT) initiated the lung cancer screening by LDCT since June 2015. Many people can get the LDCT screening with affordable price with the subsidy from enterprise donation. The purpose of this study is establishing local epidemiological result via telephone follow-up and patients' medical records retrospectively.

Lung cancer is one of the leading causes of cancer-related death in Taiwan. Early diagnosis of lung cancer may improve cancer survival. Low-dose computed tomography (LDCT) was thought to be the best screening tool for lung cancer. However, there is growing concerns about radiation exposure, high cost, and high rate of false-positive screening result. Epidemiologic studies from western countries showed that cigarette smoking is the major cause of lung cancer, and other risk factors may include age, environmental pollution, occupational exposures (included of radon exposure), gender, race, and pre-existing lung diseases. Adenocarcinoma is the major type of lung cancer in Taiwan and is less attributable to smoking. The investigators need a different risk prediction model adapted to the investigators country. National Taiwan University Hospital Chu-Tung Branch initiated the lung cancer screening by LDCT since June 2015. Many people can get the LDCT screening with affordable price with the subsidy from enterprise donation. The purpose of this study is observing those participants with 2-year follow-up. Furthermore, those data may connect with another study of "Low dose computed tomography screening study in nonsmoker with risk factors for lung cancer in Taiwan" （Non-smoker study）which is implemented in other hospitals in Taiwan.For reality limiting, After one year, the enrollment rate was a lot lower than expected. We extended the enrollment time but only observe those participants for one year not two year..
