Active clinical trials for "Lung Neoplasms"

Early detection of lung cancer and early removal of the cancer nodules facilitates the diagnosis and treatment. However, not all nodules are malignant. Currently the standard method to diagnose lung cancer is to remove any suspicious nodules from the lung in a surgical procedure. This study is being conducted to evaluate the performance of a laboratory test to detect changes in lung cells that might be an early indicator of lung cancer. The test uses mucus (sputum) which is collected in a non-invasive method. This study will compare the results of the lung biopsy with the laboratory test to determine if the test can detect cancer or the lack of cancer. The laboratory test will not be shared with the treating physician or the patient as the current standard for lung cancer diagnosis is a biopsy. Approximately 330 patients will be enrolled in the study. There is one visit involved and includes the collection of a sputum specimen by coughing into a cup. The medical records of patients who are negative for cancer by biopsy will be reviewed for 2 years to detect any changes in diagnosis.

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.

As one of the few centers, MAASTRO also aggressively re-treats patients with recurrent non-small cell lung cancer. Even after primary radical treatment to high doses, re-irradiation (with concurrent chemotherapy) is also given in curative intent, thus again using high doses of radiation. Publications on high-dose re-irradiation of lung cancer patients are scarce, and outcome and toxicity for patients treated in MAASTRO are unknown at present. This study will provide knowledge on benefit and risks of such a therapeutic approach.

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.

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.

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.

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..

Objectives: To examine whether NK cell activity associates with two confirmed risk factors: (1) presence of indeterminate lung nodule(s) and (2) smoking exposure after controlling for potential confounders, including age, gender, body mass index (BMI), personal history of any cancer, and family history of cancer. This project is aimed at measuring NK cell activity, which may eventually help in reducing false positive rates of LDCT screening, improve early detection of lung cancer, and assist in risk assessment in patients with lung cancer. The investigators hypothesize that measurement of NK cell activity may be a useful tool for assessing changes in immunosurveillance in patients with conditions or diseases where NK cell activity has been shown to be reduced, such as lung cancer

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.

Because ALK-positive lung cancer constitutes less than 5% of all lung cancers, it is critically important to select those patients who are more likely to have the ALK mutation. Clinical characteristics of patients with mutations in the target gene should also be known, so that the incidence of a given target mutation is established in a specific population. There is not incidence known in Mexican population, but it is believed it is greater.
