Quantitative imaging workshop XIX: Utilizing quantitative thoracic imaging to optimize population health final summary.

Lung cancer screening involves the use of thoracic CT for both detection and measurements of suspicious lung nodules to guide the screening management. Since lung cancer screening eligibility typically requires age over 50 years along with >20 pack-year tobacco exposure, thoracic CT scans also frequently reveal evidence for pulmonary emphysema as well as coronary artery calcification. These three thoracic diseases are collectively three of the leading causes of premature death across the world. Screening for the major thoracic diseases in this heavily tobacco-exposed cohort is broadening the focus of lung cancer screening to a more comprehensive health evaluation including discussing the relevance of screen-detected findings of the heart and lung parenchyma. The status and implications of these emerging issues were reviewed in a multidisciplinary workshop focused on the process of quantitative imaging in the lung cancer screening setting to guide the evolution of this important new area of public health.

From clinical specimens to human cancer preclinical models-a journey the NCI-cell line database-25 years later.

The intramural the National Cancer Institute (NCI) and more recently the University of Texas Southwestern Medical Center with many different collaborators comprised a complex, multi-disciplinary team that collaborated to generated large, comprehensively annotated, cell-line related research resources which includes associated clinical, and molecular characterization data. This material has been shared in an anonymized fashion to accelerate progress in overcoming lung cancer, the leading cause of cancer death across the world. However, this cell line collection also includes a range of other cancers derived from patient-donated specimens that have been remarkably valuable for other types of cancer and disease research. A comprehensive analysis conducted by the NCI Center for Research Strategy of the 278 cell lines reported in the original Journal of Cellular Biochemistry Supplement, documents that these cell lines and related products have since been used in more than 14 000 grants, and 33 207 published scientific reports. This has resulted in over 1.2 million citations using at least one cell line. Many publications involve the use of more than one cell line, to understand the value of the resource collectively rather than individually; this method has resulted in 2.9 million citations. In addition, these cell lines have been linked to 422 clinical trials and cited by 4700 patents through publications. For lung cancer alone, the cell lines have been used in the research cited in the development of over 70 National Comprehensive Cancer Network clinical guidelines. Finally, it must be underscored again, that patient altruism enabled the availability of this invaluable research resource.

Lung Cancer Workshop XI: Tobacco-Induced Disease: Advances in Policy, Early Detection and Management.

The Prevent Cancer Foundation Lung Cancer Workshop XI: Tobacco-Induced Disease: Advances in Policy, Early Detection and Management was held in New York, NY on May 16 and 17, 2014. The two goals of the Workshop were to define strategies to drive innovation in precompetitive quantitative research on the use of imaging to assess new therapies for management of early lung cancer and to discuss a process to implement a national program to provide high quality computed tomography imaging for lung cancer and other tobacco-induced disease. With the central importance of computed tomography imaging for both early detection and volumetric lung cancer assessment, strategic issues around the development of imaging and ensuring its quality are critical to ensure continued progress against this most lethal cancer.

Application of high-resolution CT imaging data to lung cancer drug development: measuring progress: workshop IX.

BACKGROUND: Lung cancer is the leading cause of cancer death and a major public health challenge across the entire world. Computed tomography (CT) imaging of the lung is a rapidly improving medical imaging technique. Spiral CT has been reported to not only improve the early detection of lung cancer in screening high-risk tobacco-exposed populations but also to assist in the clinical assessment of new agents for therapy in lung cancer. METHODS: The Prevent Cancer Foundation has sponsored a series of workshops to accelerate progress in using quantitative imaging to advance lung cancer research progress, of which this report summarizes the Ninth Workshop. The defining strategy of this forum to support innovation in quantitative research for early lung cancer management was to enable software validations by assembling collections of high-quality images for which long-term clinical follow-up is known. An additional approach was to define a process for high-quality and economical national implementation of lung cancer screening. Representatives from the Quantitative Imaging Biomarker Alliance, the International Association for the Study of Lung Cancer, the Lung Cancer Alliance, and other organizations outlined their efforts in this regard. A major opportunity exists to advance the dialogue on the use of quantitative imaging tools to cross-fertilize and accelerate image-processing research across lung cancer and chronic obstructive pulmonary disease (COPD). CONCLUSION: The use of high-resolution CT imaging provides a window into a much earlier stage of COPD as well as coronary artery disease, both being tobacco-induced diseases. Progress in this area was reviewed and opportunities for enhanced collaborative progress defined. Key sessions reviewed emerging developments with imaging technology and the infrastructure to support the storage and distribution of these high-content modalities. Cooperation among diverse collaborators is essential to enable the rapid organic evolution of this field, so that improved outcomes with lung cancer, artery disease, and COPD can be obtained.

Public attitudes toward participation in cancer clinical trials.

PURPOSE: The objective of this study is to understand the attitudes of American adults toward participation in cancer clinical trials. METHODS: A national probability sample of 1,000 adults aged 18 and older living in noninstitutional settings was interviewed by telephone by Harris Interactive during March and April 2000. One participant was selected from each household selected for the study. The resulting data were weighted to reflect the full adult population of the United States as reported in Current Population Reports. An Index of Participation in a Cancer Clinical Trial was computed, using a confirmatory factor analysis and converting the factor scores into a 0-to-100 scale. RESULTS: Approximately 32% of American adults (64 million individuals) indicate that they would be very willing to participate in a cancer clinical trial if asked to do so. An additional 38% of adults (76 million individuals) scored in a range that indicates that they are inclined to participate in a cancer clinical trial if asked, but hold some questions or reservations about participation. Projected rates of diagnosis, eligibility, and recruitment indicate that substantially more patients are willing to participate than are actually accrued. CONCLUSION: These results indicate that the primary problem with accrual is not the attitudes of patients, but rather that the loss of potential participants is the result of the unavailability of an appropriate clinical trial and the disqualification of large numbers of patients. The pool of willing patients is further reduced by the reluctance of some physicians to engage in accrual.
