Incidence rates of brain cancer following an outbreak of Chronic Fatigue Syndrome

Cheng-Te Major Lin, Naji Younes, Paul H. Levine


Previous studies utilizing data from the Nevada Cancer Registry suggested a transient increase in non-Hodgkin’s lymphoma (NHL) and brain cancer in northern Nevada following an outbreak of Chronic Fatigue Syndrome (CFS) in that area which was not seen in southern Nevada which had no reported CFS outbreaks.  A subsequent study from the National Cancer Institute (NCI) using data from the NCI’s Surveillance, Epidemiology and End Results (SEER) Program and Medicare documented the association between CFS and NHL on a national basis but no other cancer association was seen.  Since brain cancer has a younger age distribution than NHL, we returned to the Nevada Cancer Registry and used ten more years of data and additional analyses to determine if there was an association between CFS and brain cancer by age.  This study confirmed the increased incidence of brain cancer following the outbreak in northern Nevada but not southern Nevada with the increase limited to the under 65 age group, thus explaining why the SEER-Medicare analysis only analyzing data in the 65 and above age group did not detect this association.
