Active clinical trials for "Lung Neoplasms"

The purpose of this non-interventional study is to collect data on efficacy and toxicity of the use of Navelbine ORAL in daily routine in Germany (especially after availability of an 80mg capsule). The study focusses on concomitant antiemetic therapy and patient compliance.

RATIONALE: Studying samples of blood, urine, sputum, mouth cells, and bronchial tissue from healthy participants in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors learn more about the development of cancer. PURPOSE: This laboratory study is looking for molecular markers in predicting lung cancer development using tissue samples from healthy participants.

RATIONALE: Studying samples of tumor tissue and blood in the laboratory from patients with cancer may help doctors learn more about changes that occur in genetic material (DNA and RNA) and may also identify protein expression patterns related to cancer. It may also help doctors predict how patients will respond to treatment. PURPOSE: This research study evaluates changes in DNA, RNA, and proteins with the goal of predicting response to treatment in patients with lung cancer.

RATIONALE: Collecting and storing samples of tissue from patients with cancer to study in the laboratory may help doctors learn more about changes that may occur in DNA and identify biomarkers related to cancer. PURPOSE: This laboratory study is looking at epidermal growth factor receptor mutations and k-ras oncogene mutations in patients with stage III non-small cell lung cancer.

RATIONALE: Collecting samples of tumor tissue from patients with cancer to study in the laboratory may help doctors learn more about changes that may occur in DNA and identify biomarkers related to cancer. PURPOSE: This laboratory study is looking at HER-2 mutations in tumor samples from patients with advanced non-small cell lung cancer being treated with trastuzumab on clinical trial ECOG-2598.

RATIONALE: Studying samples of tissue from smokers and non-smokers in the laboratory may help doctors identify and learn more about biomarkers related to cancer. PURPOSE: This phase II study is looking at biomarkers in the nose, throat, and lung tissue of smokers and non-smokers.

RATIONALE: Radiation therapy to the brain may be effective in preventing brain metastases in patients with advanced non-small cell lung cancer. It is not yet known whether radiation therapy is more effective than observation in patients with advanced non-small cell lung cancer. PURPOSE: This randomized phase III trial is studying radiation therapy to the brain to see how well it works compared with observation in preventing brain metastases in patients with advanced non-small cell lung cancer.

This study aims to assess both the role and cost-effectiveness of EBUS in preoperative Non small cell lung cancer staging. This controlled multicentric study will be conducted in 22 centers in France. The study design includes two prospective phases. In phase 1, one investigator in each center will prospectively be evaluated for its ability to perform EBUS, with a required goal of 9 informative samplings out of 10 consecutive patients. The phase 2 will include the medico-economic assessment of the technique in the preoperative setting. A maximum of 420 patients for each phase is forecasted.

Summary: Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related death in the world. This neoplasia has a poor survival prognosis due to the low effectiveness of existing treatments. The low effectiveness is associated with the development of an intrinsic and acquired resistance of tumors, which clinically shows through early progression and transitory responses. Tobacco smoking is the major risk factor for NSCLC; however, wood smoke has been described as a strong carcinogen and a relevant risk factor for the development of NSCLC. Current data indicates that lung tumors associated with tobacco smoking and wood smoke show different clinical characteristics, which suggests that they might also have different genetic alterations, which are a consequence of tumor etiology. The description of the frequency and the type of mutations associated with different etiologies of NSCLC could represent the starting point for benefiting each patient according to their specific characteristics. One of the most researched signaling pathways related to cancer cell proliferation is the one activated by the K-RAS oncogene. Active K-RAS mutations have been detected in different types of neoplasia and more than 90% of these mutations occur at codon 12 of the oncogene. These mutations seem to be an independent risk factor for the prognosis of malignant tumors and they are associated with the lack of response to erlotinib, which is a tyrosine-kinase inhibitor. The investigators' research team has recently reported that wood smoke is an independent factor for survival and response to the erlotinib treatment, which suggests that this carcinogen could have a different frequency and pattern of mutations in the K-RAS oncogene, compared to what has been reported in smoking patients. Determining the tumor mutations within the K-RAS oncogene can help improve the response prognosis of patients with advanced NSCLC who have a background of exposure to different factors associated with the appearance of this neoplasia, such as wood smoke exposure or tobacco smoking. Therefore, the objective of this research is to determine the frequency and the type of mutations at codon 12 of the K-RAS oncogene in patients with NSCLC who have a background of exposure to tobacco smoking or wood smoke.

Inflammatory reaction in different compartments of the body may have a negative effect on outcome. This study assesses the inflammatory reaction systemically, intrapulmonary and intrapleural by measuring different cytokines. Patients with lung cancer undergoing lobectomy or segmentectomy are included in the study. Hypothesis: The inflammatory reaction in the pleural space is high compared to the systemic and intrapulmonary ones.
