Myeloid sarcoma: clinicopathologic, cytogenetic, and outcome analysis of 21 adult patients.

Abstract

Myeloid sarcoma (MS) is a neoplasm of immature granulocytes, monocytes, or both involving any extramedullary site. Twenty one patients with MS at diagnosis who were treated at King Hussein Cancer Center in Jordan were included in this retrospective study with a male to female ratio of 2 : 1. The most common site was the reticuloendothelial system. The most common morphology subtype was M2 (38%) and the most frequent chromosomal abnormality was trisomy 8. Twenty patients received induction chemotherapy; only 14 (70%) achieved complete remission. Median survival time was 24.7 months for the whole group and 58.6 months for patients who underwent allogenic bone marrow transplant. This paper showed that MS has frequent M2 morphology, carries chromosomal aberrations other than t(8;21), and requires aggressive therapy as a front line approach.
