Myelodysplastic/Myeloproliferative Neoplasms-Unclassifiable with Isolated Isochromosome 17q Represents a Distinct Clinico-Biologic Subset: A Multi-Institutional Collaborative Study from the Bone Marrow Pathology Group

Most cases fall within the WHO unclassifiable myelodysplastic/myeloproliferative neoplasms (MDS/MPN-U) category. Researchers undertook a multi-institutional retrospective study of 92 adult MDS/MPN-U cases from eight institutions.
