title: [Incidence of solid tumors in patients with chronic lymphocytic leukemia exposed to radiation after Chernobyl accident].
abstract: OBJECTIVE
  To study incidence of solid tumors in patients who developed chronic lymphocytic leukemia (CLL) after exposure to ionizing radiation after the Chernobyl accident.
  
  
  METHODS
  After analysis of data on all CLL male patients living in Kiev registered in the National Cancer Register of Ukraine in 1991-2008, these patients were divided into two groups. Group 1 consisted of 56 Chernobyl rescuers exposed to ionizing radiation, group 2 - of 684 patients without history of Chernobyl-related radiation.
  
  
  RESULTS
  Solid tumors were detected in 14 cases in group 1 and 74 cases in group 2 (p = 0.001). Risk to develop solid tumors in group 1 was significantly higher (OR 3.29 in 95% CI from 1.61 to 6.62).
  
  
  CONCLUSIONS
  The conclusion made needs further verification on wider data base.
