Active clinical trials for "Carcinoma, Non-Small-Cell Lung"

Relationship between human microbiota and epidemiology of lung cancer

Surgery may be the best treatment choice for early stage non-small cell lung cancer. And VATS major lung resection have been preferred as a standard radical procedure for early stage non-small cell lung cancer (NSCLC).This study aim to investigate the outcome of VATS major lung resection for lung cancer as a real-world study in china.

The purpose of this study is to assess whether the detection of circulating tumor cells (CTC) could be used as a tool to earlier diagnose, more accurately predict treatment response / failure and predict overall survival in non-small cell lung cancer (NSCLC) patients

A 15-gene lung signature was created to identify predictive and prognostic biomarkers for Non-Small Cell Lung Cancer (NSCLC) patients. The 15-gene signature was validated using a microarray platform with fresh frozen tumor tissue to place NSCLC patients into high risk and low risk cohorts with significantly different survivals. Using fresh frozen tissue can be challenging, so this study attempts simplify the process by migrating the 15-gene signature from fresh frozen to two alternative tissue formats: Formalin Fixed Paraffin Embedded (FFPE) and RNAlater. The gene expressions of the different tissue formats will be compared to see if the fresh frozen tissue results are similar to the alternative tissue formats.

Xenografts and cell cultures provide sufficient material for analyses at the protein, RNA and DNA level. Patient derived NSCLC xenografts and cell lines are available but none however are Asian in origin. Given the emerging evidence to suggest inter-ethnic differences in NSCLC biology, new models of preclinical drug evaluation should be designed and validated using Asian tumors. Furthermore, such models will allow studies of biological mechanisms of sensitivity and/or resistance and also the study of dynamic regulations under standardized conditions in the Asian context.

To compare the frequency of individual genetic abnormality between tumor cells and blood specimens.

The primary aim of this non interventional study is to assess the independent prognostic role on overall survival of primary tumour 18F-FDG uptake value (SUVmax) measured on 18fluorodeoxyglucose positron emission tomography (18F-FDG-PET) in patients with non-metastatic non-small cell lung cancers treated with curative intent, taking into account the other conventional prognostic factors (performance status, age, sex, disease stage).

Recently it has been suggested that specific mutations in the EGFR gene in lung cancer patients is associated with response to a novel drug targeting the EGF system. Recent research also indicates that there is a possible association to the degree of aggressiveness of the disease. The importance of these mutations is controversial, because the data are based on small studies with highly selected patients. In this project the investigators want to study the types and frequencies of EGFR mutations in both untreated and treated patients in a systematic manner and relate this to survival. The thorough registration of patient data in DK enables us to create a strong The investigators expect this knowledge to be of greatest importance for future rational use of drugs targeting the EGF receptors.

Lung cancer remains the leading cause of cancer related mortality worldwide, with more than 1.5 million related deaths annually. Lung cancer is divided into two main groups: Small Cell Lung Carcinoma (SCLC) and Non-Small Cell Lung Carcinoma (NSCLC), with prevalence of ~20% and 80% respectively. NSCLC is further subdivided into adenocarcinoma (the most common), squamous cell carcinoma (SCC), and large cell carcinoma. Furthermore, each subtype is likely to have specific mutations, which could be targeted for treatment. Medical imaging and radiomics feature extraction represent a candidate alternative to conventional tissue biopsy, a theory that is investigated in this study.
