Jennifer Brown, MD, PhD, Dana-Farber Cancer Institute, Boston, MA, provides an insight into the risk factors identified for chronic lymphocytic leukemia (CLL). Having a family member with CLL is associated with a five- to seven-fold increase in risk. However, identifying the genes responsible for this has proven challenging. Agent orange and glyphosate herbicides have been identified as potential environmental risk factors, although the data are mixed, likely due to the retrospective nature of these studies. Finally, having precursor conditions such as monoclonal B-cell lymphocytosis (MBL) may be considered a risk factor. However, Dr Brown highlights that MBL is on the biological continuum of CLL and is likely associated with the same risk factors. This interview took place at the 29th Congress of the European Hematology Association (EHA) in Madrid, Spain.
