Abstract
Objective: To study the clinicopathologic features of plasma cell myeloma(PCM) with bone marrow fibrosis (MF). Methods: The clinicopathologic data of 175 cases of newly diagnosed PCM patients were retrospectively analyzed. Based on reticular fiber staining, these cases were divided into PCM-MF and non-PCM-MF groups. Results: Sixty-three cases were PCM-MF(36%), 112 were non-PCM-MF (64%). No statistical difference in gender, age, hemoglobin level, platelet counts, the classification of immunoglobulin, ISS staging, immunohistochemical phenotypes and genetic features was found between PCM-MF and non-PCM-MF groups (P>0.05). Compared to non-PCM-MF group, lactate dehydrogenase (LDH)level and renal impairmentrate were higher in PCM-MF group (P<0.05). The degree of bone marrow hyperplasia, the percentage of myeloma cells and cells with plasmablastic morphology were significantly higher in PCM-MF group(P<0.05). Conclusion: The higher LDH level, renal impairment rate, and more significant bone marrow hyperplasia, proliferation of plasma cells and plasmablastic myeloma cells infiltration indicate poor prognosis of PCM-MF patients.
