A Snapshot of Lung Cancer

A Snapshot of Lung Cancer Incidence and Mortality Lung cancer is the second most common cancer and the primary cause of cancer-related death in both men and women in the United States. The overall mortality rate for lung and bronchus cancers rose steadily through the 1980s, peaked in the early 1990s, and has been slowly declining since 2001.http://www.dollar-essay.com/ Trends in lung cancer incidence and mortality rates have closely mirrored historical patterns of smoking prevalence, after accounting for a lag period.college essay help Because the prevalence of smoking peaked later in women than in men, lung cancer incidence and mortality rates began declining later for women than men.

The incidence rate has been declining since the mid-1980s in men but only since the mid-2000s in women; the mortality rate began declining in 1991 in men and but not until 2003 in women. Incidence and mortality rates are highest among African American men, followed by white men. Although smoking is the main cause of lung cancer, lung cancer risk also is increased by exposure to secondhand smoke ; environmental exposures, such as radon. workplace toxins (e.g. asbestos. arsenic ), and air pollution. The risk of lung cancer can be reduced by quitting smoking and by eliminating or reducing exposure to secondhand smoke and environmental and workplace risk factors. The National Lung Screening Trial has shown that screening current or former heavy smokers with low-dose helical computed tomography (CT) decreases their risk of dying from lung cancer.

Standard treatments for lung cancer include surgery. radiation therapy. chemotherapy. targeted therapy. laser therapy. photodynamic therapy. cryosurgery. endoscopic stent placement, and electrocautery . Assuming that incidence and survival rates follow recent trends, it is estimated that $11.9 billion 1 will be spent on lung cancer care in the United States in 2014.

NCI’s Investment in Lung Cancer Research To learn more about the research NCI conducts and supports in lung cancer. visit the NCI Funded Research Portfolio (NFRP). The NFRP includes information about research grants, contract awards, and intramural research projects funded by NCI.

When exploring this information, it should be noted that approximately half of the NCI budget supports basic research that may not be specific to one type of cancer. By its nature, basic research cuts across many disease areas, contributing to our knowledge of the underlying biology of cancer and enabling the research community to make advances against many cancer types. For these reasons, the funding levels reported in NFRP may not definitively report all research relevant to a given category. Source: NCI Funded Research Portfolio. Only projects with assigned common scientific outline area codes are included. A description of relevant research projects can be found on the NCI Funded Research Portfolio Web site. Other NCI programs and activities relevant to lung cancer include: Researchers with The Cancer Genome Atlas (TCGA) program are systematically identifying the major genomic changes involved in more than 20 cancers, including adenocarcinomas and squamous cell carcinomas of the lung, using state-of-the-art genomic technologies. In addition, the TCGA Pan-Cancer analysis project is comparing mutations across tumor types to identify genomic similarities; such similarities would raise the prospect that similar treatments could be useful for multiple cancer types. PubMed Abstract The Lung Cancer Master Protocol (Lung-MAP) study is a multi-arm, multi-drug trial for patients with advanced non-small cell lung cancer that has not responded to standard treatment.

This trial is unique in that it will test patients for several biomarkers by using genomic profiling, then assign patients to a new investigational treatment that specifically targets the genomic alteration that may be driving the growth of their cancer. The Adjuvant Lung Cancer Enrichment Marker Identification and Sequencing Trials (ALCHEMIST) will identify early-stage lung cancer patients with tumors that harbor certain uncommon genetic changes and evaluate whether drug treatments targeted against those changes can lead to improved survival. Follow-up studies are ongoing for the National Lung Screening Trial, which compared two ways of detecting lung cancer among people aged 55 to 74 with a history of heavy smoking: low-dose helical CT and standard chest X-ray.

The results to date show that participants who were screened with low-dose helical CT had a 20 percent lower risk of dying from lung cancer than participants who were screened with standard chest X-ray . The Physical Sciences-Oncology Centers program is bringing together cancer biologists, oncologists, and researchers from disciplines in the physical sciences to address major questions and barriers in cancer research. One center is using mathematical models to study the evolution of brain. lung. and hematologic cancers . The phase II trial Mithramycin for Lung, Esophagus, and Other Chest Cancers is examining whether mithramycin is a safe and effective drug against different chest cancers, including lung cancer. Seven lung cancerspecific Specialized Programs of Research Excellence (SPOREs) are characterizing the molecular heterogeneity of lung cancer, identifying new biomarkers of treatment response, investigating chemopreventive agents, and pursuing new treatments. Selected Advances in Lung Cancer Research Two transcription factors, GATA6 and HOPX, are critical nodes in a lung cell differentiation pathway that also inhibits the progression of lung adenocarcinoma.
