Active clinical trials for "Lung Neoplasms"

This is a descriptive observational study. The primary objective is to explore the EGFR gene mutation status in early stage NSCLC with adenocarcinoma histology after complete resection. The patients should be histological confirmed adenocarcinoma of the lung, have received complete resection and tested for EGFR mutation in regular medical practice.

The patients from 12 centers were included into the study. pN2 patients received PORT, pN1 patients did not. PORT was 3D-planned and consisted in 54-56 Gy in 27-28 fractions. One month after surgery, all patients completed EORTC QLQ C-30 questionnaires and had pulmonary function tests (PFT); cardiopulmonary symptoms were assessed by modified LENT-SOM score. Two years after, all patients free of disease repeated the same examinations. Changes in QLQ, LENT-SOM score and the results of PFT were compared for patients receiving and not PORT.

Overview of treatment reality in patients with bronchial carcinoma requiring systemic treatment and being treated by office-based oncologists in Germany.

To prospectively look at the utility of routine cervical mediastinoscopy (lymph node biopsy) in patients with clinically staged T2N0M0 NSCLC, as well as patients with clinically staged T1N0M0 NSCLC with a high maxSUV of the primary tumor on PET imaging. Hypothesis #1: The prevalence of mediastinal lymph node metastases detectable by cervical mediastinoscopy is sufficiently low (<10%) to not support the routine use of this test in the study population. Hypothesis #2: The preoperative detection of occult(hidden) N2 lymph node metastases by cervical mediastinoscopy in patients with clinically staged T2N0M0 NSCLC or T1N0M0 NSCLC with maxSUV >10 on PET does not provide a survival benefit when compared to detection of occult N2 lymph node metastases at the time of thoracotomy using nodal dissection or systematic sampling.

The primary objective of the study is to collect epidemiological data on EGFR mutation status (M+, M-) in a population of predominantly Caucasian ethnicity and to correlate EGFR mutation status with clinico-pathological characteristics (e.g. smoking status, sex, histology, etc). In particular, the study will aim to determine the frequency of EGFR M+ lung cancers in patients with clinico-pathological characteristics that are not commonly associated with EGFR mutation positivity (i.e., smokers, men, and non-adenocarcinoma).

The principal objective is to study clinical observations, symptoms and quality of life of non-small-cell lung cancer (NSCLC) patients undergoing specific non-operative treatment for cancer, including chemotherapy and radiotherapy.

The aim of this study was to retrospectively evaluate associations between EGFR and AKT DNA-polymorphisms involved in transcriptional regulation and overall survival in NSCLC patients treated with EGFR-TKIs.

The purpose of this study is to determine whether or not CTCs can be detected in blood samples taken from patients diagnosed with small cell lung cancer. The purpose is to compare CTC analysis to tumor samples to look for differences.

The proposed research intends to construct a set of tissue microarrays containing different types of normal and lung cancer tissues for the study of genes associated with lung cancer. Thus far we have generated a lung cancer tissue arrayusing paraffin embedded archival tissues from 300 lung turmors tissues and 100 adjacent normal tissues. Four- micrometer thickness sections have been cut from the tissue array and were used to survey gene expression status in arrayed tumors using immunohistochemistry methody. We are currently performing IHC studies ot 1) determine protein expression and its correlation with gene expression patterms ovserved using cDNA arrays. 2) Analyze protein expression in the chromosome remodeling pathyway in non-small cell lung cancer. And 3) determine the association of gene expression with lung tumor stage and clinical outcome. The current protocol is needed to complete the above studies and for the production of neuroendocrine tumors.

This study will explore beliefs and knowledge about genetics and smoking among smokers who have a first or second degree relative with advanced lung cancer, and whether their understanding of genetic risk influences their desire to quit smoking. Healthy adult smokers between 18 and 55 years of age who are first or second degree relatives (e.g., siblings, children, grandchildren, nieces, nephews, grandnieces or grandnephews) of a patient with advanced lung cancer who is receiving care at the Moffitt Cancer Center and Research Institute in Tampa, Fla. and the GUMC/LCCC, may be eligible for this study. Participants must be able to complete computer online surveys. Participants log on to a password-protected website to complete online educational sessions and surveys. The educational sessions include information on: 1) the role of smoking and genetics in the development of lung cancer; 2) glutathione S transferase (GSTM1), an enzyme made by the GSTM1 gene that "cleans up" toxins such as cigarette smoke and that may play a role in preventing lung cancer from developing; 3) pros and cons of being tested for GSTM1; and 5) a series of questions and answers about genetic testing. Participants are offered free genetic testing for GSTM1, and those who wish to be tested are sent materials to collect a sample from inside the cheek using a mouth rinse and return it to a laboratory at Duke University Medical Center. They later receive their results online. Participants also complete online surveys that ask about their risk perceptions, beliefs and attitudes related to lung cancer, emotional responses to their relative's diagnosis, smoking history and motivation to quit, reactions to information about smoking and genetic risk, and interest in receiving smoking cessation services. They are asked to review depictions and descriptions of smoking cessation materials offered through a quit smoking program at Duke University Medical Center and to evaluate the extent to which the various materials might be helpful. They are offered additional information among categories they can choose from. Participants are surveyed again by telephone 6 months after completing the online surveys.
