Lung Cancer Prevention (PDQ®): Prevention - Patient Information [NCI] - What is prevention?
Cancerprevention is action taken to lower the chance of getting cancer. By preventing cancer,the number of new cases of cancer in a group or population is lowered. Hopefully,this will lower the number of deaths caused by cancer. To prevent new cancers from starting,scientists look at risk factors and protective factors. Anything that increases your chance of developing cancer is called a ...

Malignant Mesothelioma Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Cellular Classification of Malignant Mesothelioma
Histologically, these tumors are composed of fibrous or epithelial elements or both. The epithelial form occasionally causes confusion with peripheral anaplastic lung carcinomas or metastatic carcinomas. Attempts at diagnosis by cytology or needle biopsy of the pleura are often unsuccessful. It can be especially difficult to differentiate mesothelioma from adenocarcinoma on small tissue specimens. Thoracoscopy can be valuable in obtaining adequate tissue specimens for diagnostic purposes. Examination of the gross tumor at surgery and use of special stains or electron microscopy can often help. The special stains reported to be most useful include periodic acid-Schiff diastase, hyaluronic acid, mucicarmine, CEA, and Leu M1. Histologic appearance seems to be of prognostic value, and most clinical studies show that patients with epithelial mesotheliomas have a better prognosis than those with sarcomatous or mixed histology mesotheliomas.[2,3,4]References: Boutin C, Rey F:
Non-Small Cell Lung Cancer Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Stage IIIB NSCLC Treatment
Based on the Surveillance, Epidemiology, and End Registry, the estimated incidence of stage IIIB NSCLC is 17.6%. The anticipated 5-year survival for the vast majority of patients who present with clinical stage IIIB NSCLC is 3% to 7%. In small case series, selected patients with T4, N0-1 disease, solely as the result of satellite tumor nodule(s) within the primary lobe, have been reported to have 5-year survival rates of 20%.[3,4][Level of evidence: 3iiiA]Standard Treatment Options for Stage IIIB NSCLCStandard treatment options for stage IIIB NSCLC include the following:Sequential or concurrent chemotherapy and radiation therapy.Chemotherapy followed by surgery (for selected patients).Radiation therapy alone.For treatment of locally advanced unresectable tumor in patients who are not candidates for chemotherapy.For patients requiring palliative treatment.In general, patients with stage IIIB NSCLC do not benefit from surgery alone and are best managed
Lung Cancer Prevention (PDQ®): Prevention - Patient Information [NCI] - General Information About Lung Cancer
Lung cancer is a disease in which malignant (cancer) cells form in the tissues of the lung.The lungs are a pair of cone-shaped breathing organs in the chest. The lungs bring oxygen into the body as you breathe in. They release carbon dioxide, a waste product of the body's cells, as you breathe out. Each lung has sections called lobes. The left lung has two lobes. The right lung is slightly larger, and has three lobes. A thin membrane called the pleura surrounds the lungs. Two tubes called bronchi lead from the trachea (windpipe) to the right and left lungs. The bronchi are sometimes also involved in lung cancer. Tiny air sacs called alveoli and small tubes called bronchioles make up the inside of the lungs. Anatomy of the respiratory system, showing the trachea and both lungs and their lobes and airways. Lymph nodes and the diaphragm are also shown. Oxygen is inhaled into the lungs and passes through the thin membranes of the alveoli and into the bloodstream (see inset).There are two
Non-Small Cell Lung Cancer Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Treatment Option Overview for NSCLC
In NSCLC, results of standard treatment are poor except for the most localized cancers. All newly diagnosed patients with NSCLC are potential candidates for studies evaluating new forms of treatment. Surgery is the most potentially curative therapeutic option for this disease. Postoperative chemotherapy may provide an additional benefit to patients with resected NSCLC. Radiation therapy combined with chemotherapy can produce a cure in a small number of patients and can provide palliation in most patients. Prophylactic cranial irradiation (PCI) may reduce the incidence of brain metastases, but there is no evidence of a survival benefit and the effect of PCI on quality of life is not known.[1,2] In patients with advanced-stage disease, chemotherapy or epidermal growth factor receptor (EGFR) kinase inhibitors offer modest improvements in median survival, though overall survival is poor.[3,4]Chemotherapy has produced short-term improvement in disease-related symptoms in patients with
Non-Small Cell Lung Cancer Treatment (PDQ®): Treatment - Patient Information [NCI] - Treatment Option Overview
There are different types of treatment for patients with non-small cell lung cancer.Different types of treatments are available for patients with non-small cell lung cancer. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.Nine types of standard treatment are used:Surgery Four types of surgery are used to treat lung cancer:Wedge resection: Surgery to remove a tumor and some of the normal tissue around it. When a slightly larger amount of tissue is taken, it is called a segmental resection.Wedge
Lung Cancer Screening (PDQ®): Screening - Patient Information [NCI] - What is screening?
Screening is looking for cancer before a person has any symptoms. This can help find cancer at an early stage. When abnormal tissue or cancer is found early,it may be easier to treat. By the time symptoms appear,cancer may have begun to spread. Scientists are trying to better understand which people are more likely to get certain types of cancer. They also study the things we do and the ...
