SHANGHAI HEALTH STUDY
Main Messages for use with Media
As part of ongoing individual product stewardship and safety and health programs, a consortium of petroleum and chemical companies has sponsored an independent, scientifically rigorous, research project to further the current understanding of the human health effects of benzene.
The study is a project of Fudan University1, the University of Colorado
Health Sciences Center, Applied Health Sciences, Inc. and Cinpathogen, Inc. Other participants in China include the Shanghai Municipal Center for Disease Prevention and Control and the Shanghai Institute for Public Health and Supervision. The research protocols were subjected to independent reviews by outside experts, including reviews of their consistency with international ethical standards and reviews by an expert scientific panel. The research protocols also have been approved by independent review boards at Fudan University and the University of Colorado.
A state-of-the-art clinical and molecular laboratory was established on the Fudan University campus. The lab supported the research project and the Shanghai medical community and the Fudan-Cinpathogen Clinical & Molecular Research Center will remain at Fudan once the project is completed. This sustainable technology transfer was an important aspect of the project design.
The results of this study are being published in scientific journals. Details of the findings will be presented there and further information may be produced by the investigators over the coming years.
The companies that funded this study had no role in the design or operation of the research and analyses conducted. This was overseen by an independent Scientific Review Panel. Additionally, an Ethics Review Panel was established to oversee those aspects of the study.
1 Fudan University, located in Shanghai, China" is one of the oldest, most prestigious and most selective universities in the People's Republic of China.

Study protocols, including data management processes, were addressed with the assistance of independent Scientific Review and Ethics Review Panels. Both panels have remained available to the investigators throughout the research program.
The independent Scientific Review Panel, composed of international experts in relevant scientific disciplines, endorsed the research protocols following several reviews and revisions.
The independent Ethics Review Panel thoroughly reviewed the study protocols (e.g. informed consent, data management) to ensure they met international standards for human research. The panel consists of bioethicists from the U.S., China, and Europe.
Q: What did the study do? A: A state-of-the-art clinical and molecular laboratory was established on the Fudan University campus. From 2003-2007, this study funded the collection and analysis of more than two thousand cases of blood disease in the Shanghai area. Patients with blood diseases in the Shanghai area were referred to the study laboratory for evaluation and diagnosis. Estimates of personal exposures to benzene were also made. Detailed and thorough analysis and interpretation of the data are underway by the researchers.
Q: What have the researchers found? A: Since 2005, the independent researchers have been presenting information on the study design to a variety of scientific audiences. The investigators will present findings from the study at the September, 2009 Munich Benzene Symposium. Those findings have been and will continue to be published in the peer-reviewed literature. Further detail can be provided by the appropriate Principal Investigator; see the Principal Investigator Contact Information list.
Q: What will happen to the laboratory after the study? A: The lab, which has supported the research project, the Shanghai medical community and the Fudan-Cinpathogen Clinical & Molecular Research Center, will remain at Fudan once the project is completed.
Q: How much did the study cost? A: While the funding of specific grants and contracts under this study is confidential, more than $30 million has been spent on this effort.
Q: Why has the study been so expensive? A: This is an extremely thorough, complex study. It has involved:
Establishment of a state-of-the-art world class laboratory Recruitment of thousands of cases over many years Planning and conduct of three distinct research studies.

Science and the Shanghai Health Study
Summary of Current Benzene Science
The major effects of benzene are chronic (long-term) impacts on the body's blood forming tissue. At high enough exposures, benzene damages the bone marrow and can cause a decrease in red blood cells, leading to anemia. Benzene is also a cause of a particular type of leukemia, acute myelogenous leukemia (AML).
Shanghai Health Study
Preliminary research design and feasibility studies based upon site visits by Principal Investigators and industrial hygiene personnel in 1999; initial site visits documented Relatively high exposure levels Sufficient numbers of cases of disease to perform valid studies Willing scientific collaborators who are research oriented
Protocols for three closely related studies were developed:
Study 1, "Case Control Study" uses a common epidemiological study design, to examine the risk of AML and lymphoid cancers like Non-Hodgkin Lymphoma (NHL) among benzene exposed workers and attempts to determine the dose response curve in the event an association is seen. Both cases and controls were prospectively collected. This study will: ~ Develop exposure information based upon historical workplace monitoring information and questionnaire ~ Explore other potential causal factors for AML and lymphoid neoplasms. ~ Include information on lymphoid and AML subtypes
Study 2, "The Disease Progression Study" is a prospective investigation of the relationship between non-cancer bone marrow diseases (such as MDS, AA, or "benzene poisoning") and benzene induced AML. It will examine: ~ Whether benzene-induced AML exhibits a molecular pattern that is different than spontaneous AML ~ What is the specific mechanism by which benzene causes leukemia ~ Are there biological markers of benzene induced AML?
Study 3, "The Molecular Epidemiology Study" is a study to examine whether there is a quantitative relationship between benzene exposure and potential early indicators (biomarkers) of both exposure and effect. It will seek to answer: ~ What levels of benzene are associated with biomarkers of exposure and/or disease? ~ Is there an association of blood effects with genetiC polymorphisms? ~ Do biomarkers of exposure validate workplace airborne exposure measurements of benzene?

The Three Studies Meet Several Technical, Ethical and Cultural Challenges
Technical - Studies are large and incorporate the latest technology including the WHO 2002 criteria for classification of Iymphohematopoetic cancers. A Scientific Review Panel made up of leading experts from a number of fields relevant to these studies has reviewed and endorsed the research protocols. Additionally, the protocols have been reviewed and approved by Institutional Review Boards (lRBs) both in the US and China.
Ethical - Study protocols meet international standards as reviewed and endorsed by an Ethics Panel consisting of leading international ethics experts. Subjects and participating communities benefit from having participated in the study through expert diagnosis and evaluation of blood disorders and confidentiality is preserved.
Cultural -Collaborators on these studies included researchers from the Medical School at Fudan University, the Institute for Public Health Supervision, and the Shanghai Municipal Centers for Disease Control and Prevention (the latter two are responsible for occupational exposure monitoring and enforcement in Shanghai).
In summary these studies were a significant opportunity to obtain a better understanding of the mechanism of benzene induced disease in humans; as the results of the studies are published, the knowledge may enhance the current assessment of the impacts of benzene exposure on health.
What Has The Shanghai Health Study Accomplished?
From 2003-2007, this study funded the collection and analysis of more than two thousand cases of blood disease in the Shanghai area. Measurements and estimates of exposures to benzene were also made. Detailed and thorough analysis and interpretation of the data are underway by the researchers.
The results of the case-control study will be presented at the Benzene 2009 Conference and later published in Chemical-Biological Interactions as part of the Conference proceedings. Additional publications are anticipated.
Some results from the Molecular Epidemiology and Disease Progression studies have already been published. Additional data and conclusions will be presented at the Benzene 2009 Conference and published as part of the Conference proceedings. Additional publications are anticipated.
