Cancer Cytogenetics Laboratory

The University of Chicago Cancer Cytogenetics Laboratory specializes in the analysis of the karyotypic pattern of hematologic malignant diseases. Established in 1960 by Dr. Janet D. Rowley, the laboratory continues its long-standing tradition of translating scientific investigation and discovery of neoplasm-associated chromosomal abnormalities into an increasing number of diagnostic services. 


Janet D. Rowley, M.D. (April 5, 1925 – December 17, 2013) 

Under the direction of Dr. Michelle M. Le Beau, Professor of Medicine, and Dr. Gordana Raca, Assistant Professor of Medicine in the Pritzker School of Medicine, the laboratory continues to pioneer the development and implementation of innovative genetic studies to strengthen the clinician's ability to provide the best possible patient care. 

Highlights of our diagnostic services include:

  • Leading-edge cytogenetic analyses as a direct result of the University of Chicago cancer genetics faculty's clinical and research expertise
  • Extensive sample analysis resulting in increased sensitivity in detecting abnormalities
  • An experienced CLSP-CG certified staff and American Board of Medical Genetics certified Directors
  • Comprehensive consultation and interpretation
  • Certification by the College of American Pathologists
  • Participation in clinical cooperative group studies, and submission of cytogenetic data to CCG, CALGB, and COG study groups
