Active clinical trials for "Lung Neoplasms"

This observational study was planned, with the primary objective to observe patient survival following first-line treatment of patients of Stage IIIB/IV Non-small Cell Lung Cancer (NSCLC) with different platinum-based doublets under routine disease management conditions. Further secondary objectives of this study are to provide insights to what extent histologic subtyping and the use of additional prognostic or predictive biomarkers are currently considered for differential therapeutic decisions under routine conditions. All of these data are critical to evaluate the factors for differential therapeutic decisions and their effect on patient outcomes in a real life setting, and they can only be obtained through observational research.

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: 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.

This randomized clinical trial studies enhanced quitline intervention in smoking cessation for patients with non-metastatic lung cancer. Stop-smoking plans suggested by doctors may help patients with early-stage cancer quit smoking

RATIONALE: Questionnaires that patients can use to assess skin toxicities related to treatment may help identify the intermediate-and long-term effects of cetuximab, panitumumab, or erlotinib hydrochloride. PURPOSE: This trial studies the validation of a cancer questionnaire for skin toxicities in patients with colorectal or lung cancer receiving cetuximab, panitumumab, or erlotinib hydrochloride.

The accurate staging is an essential part for the treatment and prognosis of non-small-cell lung cancer (NSCLC). Whole body MR imaging proved to be effective in staging of NSCLC as much as PET/CT. And there were organs of strength for each modality in the detection of metastasis. Therefore, integrated approach using whole body MR and PET would be more beneficial for the accurate staging of lung cancer with improved diagnostic efficacies and reduced radiation exposure. The aim of this project is to evaluate the diagnostic efficacy of side-by-side reading of whole-body magnetic resonance imaging/ positron emission tomography (MRI/PET) and to compare with that of whole-body magnetic resonance imaging (WB MRI) alone and that of integrated PET/CT in determining the stage of NSCLC. Patients with pathologically-proven NSCLC will be prospectively enrolled, if they are considered as surgical candidates for the treatment of lung cancer through conventional methods of staging, i.e. history taking, physical examination, blood tests, bronchoscopy, and enhanced chest CT scans. PET/CT will be routinely performed for the staging of lung cancer in our institution. For the purpose of this study, whole body MRI will be performed for these patients within 3 days from the date of acquisition of PET/CT. The results of TNM staging from each modality will be collected prospectively and their efficacies can be calculated based on the reference standards. Reference standards of T and N staging will be surgically confirmed. And M staging can be confirmed by biopsy, other imaging modalities, or follow-up more than 6 months. Diagnostic efficacies of coregistered MRI/PET can be evaluated with the comparison from the consecutive two-arm enrollment with random assignment of control group and study group as follows: control group: routine staging work-up with chest CT, PET/CT, and brain MRI study group: routine staging work-up plus whole body MRI for Coregistered MRI/PET

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 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.

Background: - Research has shown that the Epidermal Growth Factor Receptor (EGFR) gene is an important target for personalized lung cancer treatment. Individuals who have mutations in the EGFR gene have better responses when treated with certain personalized or targeted therapies compared with conventional chemotherapy. These mutations are more frequent in females with lung cancer who have never smoked, and different ethnic groups have different levels of frequency of the mutations. Researchers are interested in collecting more information on EGFR genetic mutations in Hispanics/Latinos with lung cancer, comparing the frequency of these mutations in males and females and smokers and nonsmokers. This study may lead to better, more personalized care approaches for all individuals with lung cancer. Objectives: - To study the frequency of Epidermal Growth Factor Receptor mutations in Hispanic/Latino individuals who have been diagnosed with non-small cell lung cancer. Eligibility: - Hispanic or Latino individuals who have been diagnosed with non-small cell lung cancer and who have lung tissue from a previous biopsy or surgery available for research purposes. Design: Participants will provide consent for researchers to examine lung tissue collected from a previous biopsy or surgery. Treatment will not be provided as part of this protocol.

Lung cancer in non-smokers (LCINS) is an increasing public health problem. The BioCAST (IFCT-1002) study, promoted by Intergroupe Francophone de Cancérologie Thoracique (IFCT), focuses on this entity. It is a national, multicentric, prospective epidemiological study. Main objective is to describe the clinical and molecular epidemiology of LCINS in a large French cohort composed by cases newly diagnosed in participating centres (around to 1000 patients expected). The clinical component of the study is based on collecting data directly from the patient through a standardized questionnaire during a telephone interview with a health professional. The biologic component includes a blood sample collection. A large genomic-wide association study and an epigenetic study are also planned. BioCAST hopes to provide concrete answers to clinicians and patients questions about this new and frequent entity.
