Краткое описаниеRATIONALE: Studying the amount of radiation that patients were exposed to during the
clean-up following the Chernobyl nuclear accident may help doctors learn more about the
risks of developing leukemia, multiple myeloma, and myelodysplasia.

PURPOSE: This clinical trial is studying the effect of radiation exposure on patients with
leukemia, multiple myeloma, or myelodysplasia who were clean-up workers after the Chernobyl
nuclear power plant accident.

Подробное описаниеOBJECTIVES:


- To test the hypothesis that there is a dose-related increase in risk of leukemia in the
liquidators involved in the cleanup work after the Chernobyl Nuclear Power Plant
accident in northern Ukraine in 1986.

- To test the hypothesis that the magnitude of any observed risk per unit dose in these
participants is less than that seen in the atomic bomb survivors, who were exposed to
essentially instantaneous radiation.


- To investigate the nature of dose-response relationship in these participants.

- To identify modifiers of risk (e.g., time since exposure and age at exposure) in these

- To test the hypothesis that there is a dose-related increase in risk of multiple
myeloma in these participants.

- To test the hypothesis that there is a dose-related increase in risk of myelodysplasia
in these participants.

OUTLINE: Study participants undergo an interview and complete a questionnaire to provide
information on personal and family medical histories and occupational exposure to radiation.
Participants who are deceased are evaluated via interviews with spouses or other close
relatives to obtain medical histories as well as names of co-workers at Chernobyl. Dose
estimates of radiation exposure due to the Chernobyl accident or to medical sources of
radiation (i.e., CT scans or radiopharmaceuticals) are made during the dosimetry portion of
the interview.
