Patients with stage IV NSCLC who have exon21 mutation will randomized to received oral erlotinib 150mg or gefitinib 250mg once daily until disease progression or unacceptable toxicity. Method of direct DNA sequencing of tumor tissue is used to analysis EGFR mutation status of exons 18-21. The response will be evaluated by RECIST criteria first month,second month and then repeat every 3 months after the beginning of the treatment weeks.
Allocation: Randomized, Control: Active Control, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

We hypothesize that Epidermal growth factor receptor tyrosine kinase inhibitors modulate tumor changes that may be reflected in the alteration of serum proteins. Study objectives are: ...
the purpose of this study is to evaluate the efficacy and safety of high-dose，pulsatile Erlotinib/Gefitinib in advanced non small cell lung cancer (NSCLC) patients after failure of stand...
This is a phase III, open label, randomized controlled multi-center global study designed to evaluate the safety and efficacy of single agent nazartinib (EGF816) compared with investigator...
To evaluate the efficacy and toxicity of erlotinib as first line treatment in patients with locally advanced/metastatic (stages IIIB/IV) NSCLC, with clinical predictors of response to tyro...
The purpose of this study is to determine the best confirmed response rate of daily administration of the multiple receptor tyrosine kinase (RTK) inhibitor (including EGFR and VEGFR2) XL64...
Erlotinib is used for treating non-small cell lung cancer (NSCLC). Intestinal absorption of erlotinib is impaired under gastric pH elevation, therefore, co-administration of gastric acid suppressants ...
The timely discovery of cancer cell resistance in clinical processing and the accurate calculation of drug dosage to reduce and inhibit tumour growth factor in cancer patients are promising technologi...
Adjuvant gefitinib therapy prolonged disease-free survival (DFS) in patients with resected early-stage epidermal growth factor receptor (EGFR)-mutation positive non-small cell lung cancer (NSCLC) in t...
The emergence of the T790 M gatekeeper mutation in the Epidermal Growth Factor Receptor (EGFR) gene is an important mechanism that can lead to the acquired resistance to EGFR-targeted tyrosine kinas...
Although epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) gefitinib has exhibited notable clinical efficacy in non-small cell lung cancer (NSCLC) patients. However, its therapeu...
Neoplasms of the thin serous membrane that envelopes the lungs and lines the thoracic cavity. Pleural neoplasms are exceedingly rare and are usually not diagnosed until they are advanced because in the early stages they produce no symptoms.
New abnormal growth of tissue in the THORAX.
Diseases of the cervical (and first thoracic) roots, nerve trunks, cords, and peripheral nerve components of the BRACHIAL PLEXUS. Clinical manifestations include regional pain, PARESTHESIA; MUSCLE WEAKNESS, and decreased sensation (HYPESTHESIA) in the upper extremity. These disorders may be associated with trauma (including BIRTH INJURIES); THORACIC OUTLET SYNDROME; NEOPLASMS; NEURITIS; RADIOTHERAPY; and other conditions. (From Adams et al., Principles of Neurology, 6th ed, pp1351-2)
A collective term for precoordinated organ/neoplasm headings locating neoplasms by organ, as BRAIN NEOPLASMS; DUODENAL NEOPLASMS; LIVER NEOPLASMS; etc.
Surgery performed on the thoracic organs, most commonly the lungs and the heart.
In a clinical trial or interventional study, participants receive specific interventions according to the research plan or protocol created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or change...
GILOTRIF (afatinib) is a kinase inhibitor indicated for the first-line treatment of patients with metastatic non-small cell lung cancer (NSCLC) whose tumors have epidermal growth factor receptor (EGFR) exon 19 deletions or exon 21 (L8...
Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
