Active clinical trials for "Lung Neoplasms"

Early detection of lung cancer and early removal of the cancer nodules facilitates the diagnosis and treatment. However, not all nodules are malignant. Currently the standard method to diagnose lung cancer is to remove any suspicious nodules from the lung in a surgical procedure. This study is being conducted to evaluate the performance of a laboratory test to detect changes in lung cells that might be an early indicator of lung cancer. The test uses mucus (sputum) which is collected in a non-invasive method. This study will compare the results of the lung biopsy with the laboratory test to determine if the test can detect cancer or the lack of cancer. The laboratory test will not be shared with the treating physician or the patient as the current standard for lung cancer diagnosis is a biopsy. Approximately 330 patients will be enrolled in the study. There is one visit involved and includes the collection of a sputum specimen by coughing into a cup. The medical records of patients who are negative for cancer by biopsy will be reviewed for 2 years to detect any changes in diagnosis.

This clinical trial studies deuterated phenanthrene tetraol in smokers who are at high risk for lung cancer. Studying samples of urine in the laboratory from smokers who are at high risk for lung cancer may help doctors learn more about biomarkers related to cancer.

Because ALK-positive lung cancer constitutes less than 5% of all lung cancers, it is critically important to select those patients who are more likely to have the ALK mutation. Clinical characteristics of patients with mutations in the target gene should also be known, so that the incidence of a given target mutation is established in a specific population. There is not incidence known in Mexican population, but it is believed it is greater.

This clinical trial studies whether screening methods used to diagnose cancer of the prostate, lung, colon, rectum, or ovaries can reduce deaths from these cancers. Screening tests may help doctors find cancer cells early and plan better treatment for lung cancer.

Workers exposed to asbestos are at high risk of lung cancer. Medical follow-up of this population relies on repeated CT-scans which are more accurate for detection of peripheral lesions, and expose to X-rays and to risk of false-positives. Analysis of sputum using automate cytometry may be of interest in this population, alone or in combination with CT-scan. An ancillary study will evaluate the interest of blood predictive biomarkers.

Empyema following pneumonectomy for Non Small Cell Lung Cancer (NSCLC) is a known problem that occurs in about 2% of pneumonectomy patients.

As one of the few centers, MAASTRO also aggressively re-treats patients with recurrent non-small cell lung cancer. Even after primary radical treatment to high doses, re-irradiation (with concurrent chemotherapy) is also given in curative intent, thus again using high doses of radiation. Publications on high-dose re-irradiation of lung cancer patients are scarce, and outcome and toxicity for patients treated in MAASTRO are unknown at present. This study will provide knowledge on benefit and risks of such a therapeutic approach.

Objectives: To examine whether NK cell activity associates with two confirmed risk factors: (1) presence of indeterminate lung nodule(s) and (2) smoking exposure after controlling for potential confounders, including age, gender, body mass index (BMI), personal history of any cancer, and family history of cancer. This project is aimed at measuring NK cell activity, which may eventually help in reducing false positive rates of LDCT screening, improve early detection of lung cancer, and assist in risk assessment in patients with lung cancer. The investigators hypothesize that measurement of NK cell activity may be a useful tool for assessing changes in immunosurveillance in patients with conditions or diseases where NK cell activity has been shown to be reduced, such as lung cancer

As the use of endoscopic ultrasonography for mediastinal diagnosis and/or staging is widely spread in Belgium, the investigators aimed to determine the number of mediastinoscopies needed to detect one additional mediastinal lymph node invasion during routine clinical practice in the staging of potentially resectable clinical stage III non-small cell lung cancer.

Trial design: Prospective observational study Target population: 200 NSCLC patients with histologically or cytologically confirmed stage IV or recurrent NSCLC who have progressive disease after 1st line chemotherapy who consent for study participation and meet the study selection criteria Primary objective: To investigate C-met expression/amplification and EGFR gene mutations in NSCLC patients treated with Erlotinib C-met expression by IHC C-met amplification by SISH EGFR mutation by real time PCR We will also assess the correlation of EGFR mutations and c-MET with clinical outcome (Overall Response Rate, Progression Free survival ) Duration of Trial Recruitment: 2 years
