Gefitinib is an oral selective inhibitor of the epidermal growth factor receptor tyrosine kinase which is effective for patients with advanced non-small cell lung cancer. A 75-year-old man with advanced adenocarcinoma of the lung was treated with gefitinib. He had a history of allergy to several antibiotics and Welder's lung. Two days after initiation, he developed acute interstitial lung disea...
Receptor tyrosine kinase genes were sequenced in non-small cell lung cancer (NSCLC) and matched normal tissue. Somatic mutations of the epidermal growth factor receptor gene EGFR were found in 15of 58 unselected tumors from Japan and 1 of 61 from the United States. Treatment with the EGFR kinase inhibitor gefitinib (Iressa) causes tumor regression in some patients with NSCLC, more frequently in...
BACKGROUND Factors predicting gefitinib sensitivity and adverse events in non-small cell lung cancer (NSCLC) remain controversial. PATIENTS AND METHODS Correlations among clinicopathological characteristics, gefitinib sensitivity and adverse events were studied in 154 patients with NSCLC, whereas epidermal growth factor receptor (EGFR) mutations were analyzed in 44 patients. RESULTS Female,...
Gefitinib is an oral, reversible, tyrosine kinase inhibitor of epidermal growth factor receptor (EGFR) that plays a key role in the biology of non small cell lung cancer (NSCLC). Phase I studies indicated that the recommended dose of gefitinib was 250 mg/day. Rash, diarrhea, and nausea were the most common adverse events. The positive results obtained in early phase 2 clinical trials with gefit...
Hyperactivation of Epidermal Growth Factor Receptor (EGFR) tyrosine kinase is prevalent in human lung cancer and its inhibition by the tyrosine kinase inhibitors (TKIs), including gefitinib and erlotinib, initially controls tumor growth. However, most patients ultimately relapse due to the development of drug resistance. In this study, we have discovered a STAT3-dependent Akt activation that im...
Iodine-123-metaiodobenzylguanidine ( 123 I-MIBG) kinetics in the lung could serve as a novel diagnostic tool to evaluate endothelial damage. Interstitial lung disease (ILD) associated with gefitinib, an epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI), has been reported as a serious adverse effect. This study was performed to examine the possibility that gefitinib induces...
Gefitinib is regarded as a relatively safe agent for the treatment of an advanced non-small cell lung cancer (NSCLC). Pulmonary toxicity such as interstitial lung disease associated with gefitinib is uncommon with an estimated all time incidence around 1% worldwide. Moreover, a case of gefitinib associated with pulmonary cystic changes has not been reported yet. In this report we present a case...
Gefitinib is a tyrosine kinase inhibitor that has been used for the treatment of non-small-cell lung carcinoma (NSCLC). The ability of miR-7 to enhance gefitinib-induced cytotoxicity in NSCLC cells was evaluated in this study. We found that miR-7 significantly decreased the IC50 of gefitinib and inhibited cell growth. G0/G1 cell cycle arrest and cell apoptosis were increased after the treatment...
BACKGROUND Lung cancer is a malignant carcinoma which has the highest morbidity and mortality in Chinese population. Gefitinib, a tyrosine kinase (TK) inhibitor of epidermal growth factor receptor (EGFR), displays anti-tumor activity. The present data regarding first-line treatment with single agent gefitinib against non-small-cell lung cancer (NSCLC) in Chinese population are not sufficient. ...
