Active clinical trials for "Lung Neoplasms"

RATIONALE: Sorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Drugs used in chemotherapy, such as carboplatin and paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving sorafenib together with high-dose chemotherapy and external-beam radiation therapy may kill more tumor cells. PURPOSE: This randomized phase I/II trial is studying the side effects and best dose of sorafenib when given together with high-dose carboplatin, paclitaxel, and external-beam radiation therapy in treating patients with stage III non-small cell lung cancer.

The purpose of this research study is to see if adding enoxaparin sodium to standard treatment with the chemotherapy drugs cisplatin and etoposide will help treat extensive stage SCLC. Two different doses of enoxaparin sodium will be studied in order to determine if one dose is more effective than the other. Enoxaparin sodium (Lovenox) is a drug that is approved by the FDA to help treat or prevent blood clots. Results from previous research studies suggest that adding enoxaparin sodium to standard treatment improved the response to treatment for some study participants with various types of cancer.

The purpose of this study is to examine the usefulness of a balloon covered sheath as a guide sheath in endobronchial ultrasound guided transbronchial biopsy and bronchial brushing cytology for diagnosis of peripheral lung lesions

Bone-marrow-derived progenitor cells (EPCS) play an important role in neovascularization and tumor growth. In lung cancer, angiogenesis is an important event in mechanisms of tumor proliferation and metastasis. Recent evidences suggest that EPCS can be recruited and differentiate in mature endothelial cells to form new blood vessels. The role of EPCs in NSCLC is unclear. In contrast, angiogenic drugs are proposed combined to systemic chemotherapy in NSCLC. The aim of this study is to identify EPCs in peripheral blood from patients with NSCLC, by comparison to Chronic Pulmonary Obstructive Disease (COPD), an inflammatory disease.

Primary Objective The primary objective of this phase I-II study is to evaluate: Phase I: Assess the maximum tolerated dose (MTD) of bortezomib in a weekly schedule with bevacizumab given every 3 weeks. Phase II: Using the MTD established in phase I, assess efficacy of the combination as indicated by progression-free survival. Secondary Objectives The secondary objectives of this study are to evaluate: Response rates and duration of response 1 year survival Overall survival Qualitative and quantitative toxicity Circulating endothelial cells (CECs) prior to treatment, prior to cycle 2, and/or at the time of progression

RATIONALE: Determining whether erlotinib passes into the cerebrospinal fluid may help in planning treatment for some types of cancer. PURPOSE: This clinical trial is studying how well erlotinib is able to pass into the cerebrospinal fluid of patients receiving erlotinib for stage III non-small cell lung cancer.

RATIONALE: Zinc supplements may lower cadmium levels in smokers and may help prevent DNA damage. PURPOSE: This clinical trial is studying how well zinc supplements work in lowering cadmium levels in smokers.

Proper staging of Lung cancer is of paramount concern when determining a treatment regime. Currently the assessment of surgical candidacy is performed with the staging process, mainly the mediastinoscopy. A mediastinoscopy has the ability to access samples of the paratracheal lymph node stations (Levels 2R, 2L, 3, 4R, 4L), as well as the anterior subcarinal lymph node station (Level 7). In comparison, the EBUS-TBNA technique is a real-time procedure that has the potential to access the same paratracheal and subcarinal lymph node stations associated with the mediastinoscopy, but also extending out to the hilar lymph nodes (Levels 10 and 11). Because of the possibility of extended sampling range and a reduction in procedural invasiveness, EBUS-TBNA may represent a more efficient patient centered alternative to mediastinoscopy in the staging of lung cancer patients. Additionally, patients who are have lymph nodes in the N2 region frequently undergo chemotherapy and/or radiotherapy prior to surgery. Assessment of the lymph nodes after chemo/radiation is done using CT scans, as re-mediastinoscopy is a technically difficult procedure. These patients may benefit from EBUS-TBNA.

Positron Emission Tomography (PET) is a specialised nuclear medicine procedure that uses positron emitting radiolabeled tracer molecules to measure biological activity. The most common of these radiolabeled tracers is 18F-fluorodeoxyglucose (18F-FDG), which is used to determine abnormal glucose metabolism in tumours and other sites. It has general applications in all areas where abnormal glucose metabolism may be present including in circumstances such as differentiating the tumour from scar tissue; evaluating the presence of the tumour in light of rising tumour markers and normal morphological imaging techniques; and assessing response to therapy where other techniques are deemed to be unhelpful. The Cross Cancer Institute (CCI) has recently been funded to establish a PET centre, and this study will prove the effectiveness of PET scanning in the Canadian health care environment and validate the data that have been developed in other jurisdictions in specific oncologic indications.

RATIONALE: Computer-assisted scheduling of nicotine inhaler use may be an effective method to help people stop smoking. PURPOSE: Randomized cinical trial to compare the effectiveness of computer-assisted scheduling of nicotine inhaler use with that of self-scheduled nicotine inhaler use in participants who plan to stop smoking.
