What are Hematopoietic Neoplasms?
Hematopoietic neoplasms are clonal disorders of hematopoietic cells, which constitute red cells, white cells, and platelets. They typically manifest as leukemias, lymphomas, and plasma cell disorders. Leukemias predominantly involve peripheral blood and bone marrow, while lymphomas involve tissue-based sites such as lymph nodes, stomach, or skin.
Challenges in the Accurate Diagnosis of Hematopoietic Neoplasms
As technologies have advanced beyond typical chromosome analysis to include FISH- and PCR-based testing, accurate and cost-effective diagnosis of hematopoietic neoplasms has become much more challenging for clinicians and pathologists.
To address these challenges, Mayo Clinic clinicians and pathologists work together to establish unique test guidelines, algorithms, and specimen submission options that best utilize these technologies to provide the right diagnosis for the right patient.
