Active clinical trials for "Lung Neoplasms"

RATIONALE: Studying samples of blood in the laboratory from patients receiving erlotinib hydrochloride may help doctors learn more about the effects of erlotinib hydrochloride on cells. It may also help doctors understand how well patients respond to treatment. PURPOSE: This research study is studying biomarkers predicting response in patients with non-small cell lung cancer previously treated with erlotinib hydrochloride.

RATIONALE: Diagnostic procedures, such as an urgent chest x-ray, may help in planning cancer treatment. It is not yet known whether standard medical care is more effective than an urgent x-ray in diagnosing lung cancer in smokers with chest symptoms who are older than 60 years. PURPOSE: This randomized clinical trial is studying standard medical care to see how well it works compared with an urgent chest x-ray in diagnosing lung cancer in smokers with chest symptoms who are older than 60 years.

Evaluate chemotherapy related tumor markers on non small cell lung cancer by fluorescent in situ hybridization and immunohistochemistry, targets to be studied include EGFR, c-MET, topoisomerase II, p53, topoisomerase I, thymidylate synthase, ERCC1, tau, c-myc, RRM1, class III tubulin. These targets have been chosen because they are targets for chemotherapeutic agents that are currently used in clinical management of these diseases. In total 50 specimen will be studied, approximately one third have mutations/deletions of the EGFR gene.To attempt to establish a correlation between the pre-selected tumor markers and response to chemotherapy, and thus to be able to create a clinically useful classification that would provide clinical guidance for selection of the most effective chemotherapy for a individual patient, and thus be able to logically design more effective clinical trials for the future.

RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in peptides and proteins and identify biomarkers related to cancer. PURPOSE: This research study is looking at blood samples from patients with malignant melanoma, metastatic breast cancer, advanced lung cancer, pancreatic cancer, or colorectal cancer.

RATIONALE: Screening tests, such as CT scanning, may help doctors find cancer cells early and plan better treatment for lung cancer. PURPOSE: This clinical trial is studying how well a lung cancer screening program using CT scanning works in current and former smokers.

The overall objective of the study is to assess the feasibility of the use of blood for the detection of EGFR mutations in patients with non-small cell lung cancer (NSCLC) Specific aims are: To assess the use of immuno-separation techniques to enrich the tumor cell population in the blood of NSCLC patients. To assess the use of denaturing high performance liquid chromatography (DHPLC) assay for the detection of EGFR mutations in the blood of NSCLC patients.

This is a multicenter, open-label, phase 1, dose escalation study. The purpose is to determine the highest dose of TG01 that can be safely given to patients with Non-Small Cell Lung Cancer in combination with erlotinib.

The purpose of this study is to learn how often lung cancer survivors exercise. We also want to learn what helps people to be active or prevents them from being active. Learning this will help us to expand services for lung cancer survivors.

RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This laboratory study is looking at tumor samples from patients with lung cancer.

Radiotherapy (RT) treatment to the chest is a standard way of trying to decrease symptoms like cough or shortness of breath. Before any RT can be delivered, it must be planned, either using conventional x-rays ("fluoroscopy") or using computer tomography ("CT") scanning. This study is being done because the investigators do not know which of these two common ways of RT planning is better for balancing both treating the cancer and decreasing side effects.
