Higher Incidence of Multiple Myeloma in 9/11 RespondersLast Updated: August 10, 2009.

MONDAY, Aug. 10 (HealthDay News) -- An unusually high number of World Trade Center (WTC) responders under the age of 45 years have developed multiple myeloma, according to research published in the August issue of the Journal of Occupational and Environmental Medicine.
Jacqueline M. Moline, M.D., of Mount Sinai School of Medicine in New York City, and colleagues examined cases of 28,252 WTC responders registered in the WTC Medical Monitoring and Treatment Program. The researchers reviewed charts and contacted physicians of responders for whom a diagnosis of multiple myeloma was reported, either by the responders themselves or by their physicians. They obtained confirmatory medical records and exposure information.
Among the study participants, the researchers found eight cases of multiple myeloma, though they had only expected 6.8 cases. Four of the cases were in responders who were younger than 45 when diagnosed, though only 1.2 of these cases were expected. In responders age 45 and over, four cases were observed, but 5.6 were expected.
"In this case series, we observe an unusual number of multiple myeloma cases in WTC responders under 45 years. This finding underscores the importance of maintaining surveillance for cancer and other emerging diseases in this highly exposed population," the authors write.
