RATIONALE: Some tumors need growth factors produced by the body's white blood cells to keep growing. Drugs such as ZD 1839 may interfere with the growth factors and cause tumor cells to die.
OBJECTIVES: I. Determine the efficacy of ZD 1839 in patients with metastatic renal cell cancer. II. Determine the time to disease progression in patients treated with this drug. III. Determine the safety of this drug in these patients.
OUTLINE: Patients receive oral ZD 1839 once daily. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients are followed for at least 1 month.
PROJECTED ACCRUAL: A total of 16-46 patients will be accrued for this study within 1 year.
Primary Purpose: Treatment

This purpose of this study is to compare the effects (good and bad) of chemotherapy (docetaxel) plus ZD1839 (Iressa, gefitinib) with docetaxel and placebo on the head and neck cancer to se...
RATIONALE: Biological therapies such as gefitinib may stimulate the immune system in different ways and stop cancer cells from growing. It is not yet known whether gefitinib is effective i...
RATIONALE: Biological therapies such as gefitinib may interfere with the growth of the tumor cells and slow the growth of cervical cancer. Comparing results of diagnostic procedures perfor...
RATIONALE: Gefitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. PURPOSE: This phase II trial is studying how well gefitinib works in treati...
The purpose of this study is to provide gefitinib treatment to patients who, on completion or closure of other gefitinib clinical studies, were either receiving placebo treatment, or are c...
Gefitinib have been widely used in the first-line treatment of advanced EGFR-mutated non-small-cell lung cancer (NSCLC). However, many NSCLC patients will acquire resistance to gefitinib after 9-14 mo...
Overcoming EGFR-TKI resistant which has the initial enthusiasm over substantial clinical responses is a formidable challenge on nowadays. In this study, we showed that cholesterol level in lipid rafts...
The aim of this study is to evaluate the long term survival of the addition of gefitinib to chemoradiotherapy (CRT) in locally advanced rectal cancer (LARC).
Mutant EGFR Non-small cell lung cancer has benefit from gefitinib, but it has limited effect for wild-type EGFR tumors. Shikonin, a natural naphthoquinone isolated from a traditional Chinese medicine,...
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...
A complication of kidney diseases characterized by cell death involving KIDNEY PAPILLA in the KIDNEY MEDULLA. Damages to this area may hinder the kidney to concentrate urine resulting in POLYURIA. Sloughed off necrotic tissue may block KIDNEY PELVIS or URETER. Necrosis of multiple renal papillae can lead to KIDNEY FAILURE.
The outer zone of the KIDNEY, beneath the capsule, consisting of KIDNEY GLOMERULUS; KIDNEY TUBULES, DISTAL; and KIDNEY TUBULES, PROXIMAL.
Long convoluted tubules in the nephrons. They collect filtrate from blood passing through the KIDNEY GLOMERULUS and process this filtrate into URINE. Each renal tubule consists of a BOWMAN CAPSULE; PROXIMAL KIDNEY TUBULE; LOOP OF HENLE; DISTAL KIDNEY TUBULE; and KIDNEY COLLECTING DUCT leading to the central cavity of the kidney (KIDNEY PELVIS) that connects to the URETER.
Stones in the KIDNEY, usually formed in the urine-collecting area of the kidney (KIDNEY PELVIS). Their sizes vary and most contains CALCIUM OXALATE.
Abnormal enlargement or swelling of a KIDNEY due to dilation of the KIDNEY CALICES and the KIDNEY PELVIS. It is often associated with obstruction of the URETER or chronic kidney diseases that prevents normal drainage of urine into the URINARY BLADDER.
Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
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...
Nephrology - kidney function
Nephrology is a specialty of medicine and pediatrics that concerns itself with the study of normal kidney function, kidney problems, the treatment of kidney problems and renal replacement therapy (dialysis and kidney transplantation). Systemic conditions...
