Blood cell clues may spot bone marrow changes early in leukemia

This study will check if certain blood cell markers, called reticulocytes, can serve as early signs of bone marrow activity in people with chronic B lymphoproliferative neoplasms, a type of blood cancer. Researchers will measure reticulocyte counts and maturity levels in 120 newly diagnosed adults who have not yet received treatment. The goal is to see if these simple blood tests can help doctors understand bone marrow function without more invasive procedures.
