About this study
Lung Cancer continues to be the major cause of cancer-related mortality in Singapore. Non-small cell lung cancer (NSCLC) accounts for 75% of lung cancers and adenocarcinoma is the most common histological subtype. Although cigarette-smoking is the main cause of lung cancer, more than a third afflicted in Singapore are never-smokers and 69% affect females. For the majority who present with advanced NSCLC, chemotherapy is the mainstay of treatment. Despite advances made with newer chemotherapeutic agents, it is apparent that the benefit of conventional chemotherapy has plateaued. Efforts toward developing novel treatments based on growing understanding of molecular oncology have yielded drugs that target vascular endothelial growth factor (VEGF) and epidermal growth factor receptor (EGFR). They have expanded treatment options for patients with advanced NSCLC. However, monoclonal antibody to VEGF is contraindicated in patients with squamous cell carcinoma due to increased incidence of fatal hemoptysis. EGFR tyrosine kinase inhibitors (EGFR-TKI) appear promising but only 40% of east-asian female never-smokers with lung adenocarcinoma harbour EGFR gene mutations. Estrogen, KRAS, BRAF, ERBE and other genetic mutations can confound response. Molecular data obtained from Caucasian and predominantly east-asian population may not apply to our multi-ethnic groups and our aim is to determine the molecular characteristics of our multi-ethnic asian phenotypes to better understand the process of carcinogenesis and treatment response as well as identify potential novel targets for future drug development. Paraffin-embedded tissues are recalled, and DNA is extracted for mutational analysis, which will be correlated to patient demographics, treatment and outcome.
Read the detailed description
Lung cancer is a malignant disease of heterogeneous histology and is divided into 2 major groups; small cell lung cancer and non-small cell lung cancer (NSCLC). NSCLC accounts for 75% of lung cancers, and can exhibit different pathways of resistance during treatment. It is increasingly apparent that effective treatment of NSCLC will require multiple drugs that attack different targets. This realization sets the stage for future individualized therapies that will depend on the molecular characteristics of NSCLC to target various pathways.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 24 Jan 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Singapore. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
