Active clinical trials for "Lung Neoplasms"

This study evaluate multiple-portal VATS and uniportal VATS lobectomy for NSCLC, half of participants will receive multiple VATS, while the other half will receive uniportal VATS lobectomy.

The purpose of the study is to determine if rapid on-site evaluation of EBUS-TBNA samples can increase the percentage of patients with advanced non-squamous non-small cell lung cancer in whom both pathologic subtyping and mutational analysis are obtained.

The need of radiosurgery is controversial for asymptomatic oligo brain metastasis for non small cell lung cancer (NSCLC). Therefore, the investigators do a randomized study comparing overall survival between two groups with or without radiosurgery for asymptomatic oligo brain metastasis before palliative chemotherapy for NSCLC.

This clinical trial studies computed tomography (CT) in diagnosing patients with lung cancer. Diagnostic procedures, such as CT, may help find and diagnose lung cancer.

Non-Small Cell Lung Cancer (75% of lung cancer) is associated with involvement of the parietal pleura and or chest wall (soft tissue and/or bone) in 5-8% of patients. Invasion of the chest wall increases the T staging in the Tumor, Node, Mestasis (TNM) classification system of lung cancer to a T3 and is associated with decreased survival and more extensive operative procedures. The reported 5-year survival for patients with T2 tumors is 58% compared to 38% in patients with T3 lesions. The American college of Chest Physician has still not identified the best tool to assess chest wall invasion by lung cancer, CT-Scan being used by physicians for this assessment. In some studies, CT scan has been shown to have a sensitivity ranging from 42 % to 68 % in assessing chest wall invasion, and a specificity ranging from 66 % to 100 %. Trans-thoracic Ultrasound (US) has the capacity of allowing for dynamic real-time imaging of the pulmonary lesion and the chest wall. Therefore, US has the potential to allow for the appreciation of subtle findings related to the movement of the lesion and lung over the chest wall. Hence, US might be an accurate tool to assess chest wall invasion by lung cancer; thus improving pre-operative diagnosis, staging and operative planning of patient with chest wall invasion. However US is not currently utilized in the pre-operative assessment of patients with lung cancer invading the pleura and chest wall, and has not been extensively studied. In some rare studies evaluating the accuracy of US, results have shown a sensitivity ranging from 89% to 100% and a specificity ranging from 95% to 98% for US detecting chest wall invasion by lung cancer. However those studies got criticized. Bandi et al study, got criticized by the fact that the operators in the study were experienced interventional pulmonologists who perform hundreds of thoracic and endoscopic ultrasound per year. Nobuo et al study took place in 1993, since when the device of US has evolved, the investigators can not apply with certainty the findings of this study. Consequently, there is a need to conduct a study to evaluate the accuracy of US to assess chest wall invasion by lung cancer. In this prospective study the investigators will assess the accuracy of US, and then compare it to the accuracy of the CT-Scan

Early Lung Cancer diagnosis in a HIV-infected population with an important smoking history with low-dose CT: a pilot study: the HIV-CHEST study Objectives The main objective of this study is to evaluate the prevalence of lung cancers detected by low-dose computed tomography (CT) in a HIV-infected population with an important smoking history. Other objectives are (1) the evaluation of the types of lung cancers in this population, as well as (2) the staging of non small cell lung cancers, (3) the description of risk factors for all lung cancers, if they are numerous enough, and (4) the number of complications of diagnosis procedures during the study.

This study is intended to assess the feasibility of adjusting a radiation plan during its course to accommodate for a shrinking tumor target. The investigators hypothesize that an adaptive radiotherapy (RT) planning strategy for small cell lung cancer (SCLC) patients with chest-confined disease will allow for safe delivery of higher doses of chest RT than a non-adaptive RT planning approach without subjecting normal critical structures to unacceptable doses of radiotherapy.

Objective: the objective of this study in china is to clarify, whether the overall survival is different between previously untreated stage IIIB/IV lung adenocarcinoma with EGFR mutations receiving first-line erlotinib plus second-line docetaxel/cisplatin and those receiving first-line docetaxel/cisplatin plus second-line erlotinib .

The prognosis of NSCLC patients with asymptomatic brain metastasis, who are not treated with SRS or WBRT has not been fully investigated yet. This randomized phase III trial is conducted to determine the exact role of SRS in NSCLC patients with asymptomatic oligo brain metastases whether early treatment with SRS would improve survival even in patients with asymptomatic brain metastasis.

The purpose of this study is to determine the recommended dose of pemetrexed and the maximum tolerated dose of radiotherapy when using concurrent pemetrexed/cisplatin/radiotherapy in the patients with local advanced non-small cell lung cancer.
