Active clinical trials for "Lung Neoplasms"

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.

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.

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.

The overall aim of the study is: To provide accurate and reliable information regarding NSCLC clinical management across MENA region in order to detect unmet medical needs of this disease in terms of: Patient and hospital characteristics. Diagnostic and treatment approaches: initial and subsequent. Follow-up patterns in clinical management. Outcomes: symptoms, death, functionality, quality of life. Use of resources and burden on patients and health care systems.

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

With roughly 80% of cancer patients receiving their oncology care in the community setting, the investigators are proposing to sample from a community-based center to evaluate the percentage of epidermal growth factor receptor (EGFR)-wild type patients that gain benefit from erlotinib and assess the clinical characteristics that are associated with erlotinib-responders. Additionally, biopsy specimens from enrolled patient cases that are EGFR-wt will be evaluated via exploratory genetic analysis for correlated markers.

Management of lung cancer remains very controversial for elderly patients (pts) and they are often excluded from clinical trials. We present here a survey performed about the management of lung cancer pts aged 70 or more in France. All pts aged 70 or more with histo/cytologically proved lung cancer diagnosed between sept 02 and oct 03 in participating centers were recorded and their characteristics, the diagnostic procedures, therapeutic management and survival were analysed.

The purpose of the study is to identify a surrogate serum marker for tumor hypoxia in patients with lung cancers.

This is a multi-center retrospective study, designing to access the best treatment strategy in non-small cell lung cancer (NSCLC) patients harboring EGFR mutant type after first/second line EGFR-TKI failure. The study end point is Progression Free Survival 2 (PFS2), which is defined as the time period from Progression Disease 1(PD1) to Progression Disease 2(PD2). PD1 is defined as the first tumor progression time from taking EGFR-TKI evaluated by Recist 1.1 criterion, and PD2 as the second tumor progression time after EGFR-TKI failure no matter what second/third line treatment was, PD2 is also evaluated by Recist 1.1 criterion.

Crizotinib, an inhibitor of anaplastic lymphoma kinase (ALK), was approved by Food and Drug Administration (FDA) for the treatment of patients with ALK-positive non-small cell lung cancer (NSCLC) and its administration has achieved considerable success. However, adverse effects inevitably occurred and the most common one was hepatic toxicity, appearing as elevating alanine aminotransferase(ALT) and aspartate aminotransferase(AST). Therefore, the investigators try to figure out the mechanism of crizotinib-inducing hepatic toxicity, and explore whether there is any biological marker to diagnose this side effect in an early stage, which may realize individualized therapy with more efficacy and less side effects.
