What is the Shanghai Health Study?
::i:::i!::} A long-term clinical study to investigate the potential causes and development of Iympho-hematopoietic diseases (diseases of the lymphoid organs, blood and bone marrow) as related to benzene
::i:::i!;:} A project of Fudan University Medical Center; University of Colorado Health Sciences Center; Applied Health Sciences - an independent U.S. research firm; Chinese public health agencies; and Shanghai hospitals

Shanghai Health Study Purpose
C) To gain a quantifiable understanding of the relationship between benzene exposure and potential associated cancer risks
SH ELL-MCCLU RG-06S476
Path to developing the study:
t:;::::~:: Pre-9 7: 97::~: :;:;: : :
Benzene exposure associated with AML NCI published conclusions from China study that:
- Benzene can cause NHL - AML develops at exposures lower than previously known - no
th reshold observed
NCI Methodology criticized Feasibility studies in Shanghai Australian Institute of Petroleum's (AlP) Health Watch Study
- Association with all leukemias, including chronic lymphocytic leukemia
- No association with NHL or multiple myeloma
Benzene Health Research Consortium formed to:
- do a study to test conclusions - answer questions of disease progression and biomarkers
SH ELL-MCCLU RG-06S477
Benzene exposure and cancer
Conclusions from pre-1997 Epidemiology
'::::11:I!l1::::: Only acute myelogenous leukemia (AML) associated with benzene
::::!{::1 No risk at exposures < 1 ppm :::::=::::1 Clear risk at exposures > 20 ppm
Iit:il Insufficient data at 1-20 ppm to assess risk
SH ELL-MCCLU RG-06S478
The Shanghai Health Study
1. Case Control Study Traditional, prospective epidemiology study to determine risk of AML, NHL among benzene exposed workers - 450 AML and 450 NHL patients into study
2. Disease Progression Study Prospective study on relationship of non-cancer bone marrow disease and benzene induced AML
3. Molecular Epidemiology Study Prospective study to establish quantitative relationship between exposure and effect
SH ELL-MCCLU RG-06S479
Uniqueness ofShanghai Study
Prospective resea rch::::I!:;;!I:::::
Ii'::::l Patients at participating hospitals suspected of having a lymphoid, blood or bone marrow disease will be referred to the SHS
::::g:::l Patients' diets, environmental exposures and family histories will be recorded
If::::l Patient disease progression followed at supporting hospitals
SH ELL-MCCLU RG-06S480
Uniqueness ofShanghai Study
::::1::;;:1::::: Study will be able to examine primary diagnostic and medical data in real time
::::::::1:1::::::: First-hand exposure reports are more reliable than second-hand or reconstructed information
::::::::11::::::: State-owned databases document worker histories
SH ELL-MCCLU RG-06S481
Uniqueness ofShanghai Study
:~::~:;:~::i: Robust data set
::::g:::l State-maintained benzene exposure and health effects databases documented from 1970s
:~:;:~:l Benzene related health effects are #2 in reported chronic occupational health hazards in China in 2001 (Source: Ministry ofPublic Health)
:~:I:~:l Large range of exposure levels from a variety of occupational sources
:~:~:;:~:i: Regulatory authorities interest in improving benzene exposure regulation and enforcement
