Reason for investigation

Reason for Investigation

  • Concerns about increased cancer near the NAS

  • Requests by:

    • Senator Michael Morrissey,

    • Weymouth Board of Health, and

    • Concerned residents in Rockland, Weymouth, Abington, and Hingham

Massachusetts Department of Public Health, Bureau of Environmental Health Assessment


Community cancer concerns

Community Cancer Concerns

  • Suspected increases in cancer in the four towns

  • Possible link to environmental contamination present at NAS

  • Suspected increases in cancer in other areas of the four towns unrelated to NAS

Massachusetts Department of Public Health, Bureau of Environmental Health Assessment


Investigative approach

Investigative Approach

  • Calculate cancer rates for each town and by smaller areas (census tracts)

  • Evaluate geographic patterns of cancer in each town

  • Evaluate patterns of cancer in relation to environmental sources (particularly NAS)

Massachusetts Department of Public Health, Bureau of Environmental Health Assessment


Massachusetts cancer registry

Massachusetts Cancer Registry

  • Population-based surveillance system established in 1982

  • Massachusetts law requires reporting of all newly diagnosed primary cancers in Mass. residents

  • Confidential database

Factors considered

Factors Considered

  • Cancer may be caused by one or many different factors

  • Review of MCR data on cancer risk factors

    • age/gender

    • smoking history

    • occupation

Massachusetts Department of Public Health, Bureau of Environmental Health Assessment


Lung cancer risk factors

Lung Cancer Risk Factors

  • Age

  • Smoking

  • Second-hand smoke

  • Occupation/environmental exposures

Massachusetts Department of Public Health, Bureau of Environmental Health Assessment


Review of risk factors lung cancer

Review of Risk Factors:Lung Cancer

  • Age and gender patterns did not appear unusual

  • Workplace exposures may have played a role in some diagnoses

  • Majority of those with lung cancer were current or former smokers

Massachusetts Department of Public Health, Bureau of Environmental Health Assessment

Cancer rates by census tract

Cancer Rates by Census Tract

  • SIRs were also calculated for the census tracts that subdivide each of the four towns

    • 8 CTs in Weymouth

    • 3 CTs in Abington

    • 3 CTs in Hingham

    • 2 CTs in Rockland

Review of risk factors pancreatic cancer

Review of Risk Factors:Pancreatic Cancer

  • Age patterns were as expected

  • More women than men were diagnosed with pancreatic cancer

  • Workplace exposures possible

  • Smoking may have played an important role for some individuals

Review of risk factors leukemia

Review of Risk Factors: Leukemia

  • Age and gender patterns did not appear unusual

  • A variety of different leukemia subtypes were reported

  • Workplace exposures may have played a role in some diagnoses

Massachusetts Department of Public Health, Bureau of Environmental Health Assessment


Evaluation of geographic distribution

Evaluation of Geographic Distribution

  • Place of residence at time of diagnosis was mapped for each individual

  • Patterns of individuals diagnosed with cancer were evaluated spatially

  • Other factors that may indicate a cluster were considered

Massachusetts Department of Public Health, Bureau of Environmental Health Assessment


Community environmental concerns

Community Environmental Concerns

  • Naval Air Station

  • Potentially hazardous waste sites (21E sites)

  • Weymouth Neck Landfill

  • Specific community environmental concerns in Weymouth and Hingham

  • Suburban Auto and two landfills in Rockland

Massachusetts Department of Public Health, Bureau of Environmental Health Assessment


Sources of environmental information

Sources of Environmental Information

  • ATSDR Public Health Assessment

  • Environmental Baseline Study

  • ATSDR Private Well Survey

  • Modeled Flight Track Patterns

  • Recent Investigations in NW corner of NAS

Massachusetts Department of Public Health, Bureau of Environmental Health Assessment


Summary of geographic distribution analysis

Summary of Geographic Distribution Analysis

  • With the exception of lung cancer, no consistent spatial patterns were observed in any one area of the four towns

  • The geographic pattern of cancer did not show a clear pattern suggesting a common environmental exposure related to the NAS

  • Patterns of cancer near other areas of community environmental concern were not atypical

Conclusions

Conclusions

  • Majority of cancer types occurred at or near the expected rates in the four towns between 1982-1998

  • Lung cancer is increasing in Weymouth and Rockland, particularly in CTs near the NAS

  • Evaluation of risk factors showed smoking likely played a role in increased lung cancer rates

  • Occupation also played a role in lung cancer for some individuals

Massachusetts Department of Public Health, Bureau of Environmental Health Assessment


Conclusions cont

Conclusions (cont.)

  • With the exception of lung cancer, patterns by census tract showed no consistent elevations of cancer over time

  • The geographic pattern of cancer did not show a clear pattern suggesting a common environmental exposure related to the NAS

Massachusetts Department of Public Health, Bureau of Environmental Health Assessment


Mdph recommendations

MDPH Recommendations

  • The MDPH should further investigate the pattern of lung cancer with respect to length of residence, particularly among non-smokers, to determine if a clearer pattern of this cancer emerges

  • Results should be considered by town Boards of Health when planning future prevention or intervention strategies in the four towns

Massachusetts Department of Public Health, Bureau of Environmental Health Assessment


Mdph recommendations cont

MDPH Recommendations (cont.)

  • Tobacco control efforts should be focused accordingly in the towns of Weymouth, Abington, and Rockland

  • Cancer incidence will continue to be monitored in these four towns through the use of the MCR
