NCI Cancer Bulletin - Expert Panel Reports on Knowledge Gaps for 20 Suspected Carcinogens



In a monograph released July 15, a coalition of leading health organizations called for more research into the possible cancer-causing effects of exposure to 20 chemical agents. Some of the named agents are commonly found in the environment, whereas others are more often limited to occupational exposures. A summary paper in Environmental Health Perspectives provides an overview of the technical report.

The monograph, titled Identification of research needs to resolve the carcinogenicity of high-priority IARC carcinogens, summarizes available evidence and provides specific guidance on the appropriate studies needed to definitively classify these agents. Several overarching issues were identified that pertain to multiple agents, including recognizing that carcinogenic agents can act through multiple pathways and mechanisms of toxicity.

“This report highlights the importance of conducting research in occupational settings to identify human carcinogens,” said Dr. Debra Silverman, a co-author of the report and chief of the Occupational and Environmental Epidemiology Branch in NCI’s Division of Cancer Epidemiology and Genetics. “Findings from such occupational studies often allow experts to extrapolate the possible effects of low-level exposure to these agents in the general environment.”

“There is significant concern among the public about substances or exposures in the environment that may cause cancer, and there are some common occupational agents and exposure circumstances where evidence of carcinogenicity is substantial but not yet conclusive for humans,” added the report’s lead author, Dr. Elizabeth Ward, from the American Cancer Society (ACS).

The project originated as part of the National Institute for Occupational Safety and Health’s National Occupational Research Agenda to enhance occupational cancer research, and it involves collaboration with NCI, the International Agency for Research on Cancer (IARC), the ACS, and the National Institute of Environmental Health Sciences.
