Abstract
Plasma cell leukemia (PCL) is a clinically aggressive variant of multiple myeloma, characterized by a high burden of circulating plasma cells, necessitating swift and accurate diagnosis due to its poor prognosis. The conventional diagnostic criteria, including the recent recommendation by the International Myeloma Working Group (IMWG) of > 5% circulating plasma cells as positive, have evolved over time. In this context, we present a detailed case report that underscores the pivotal role of the ADVIA 2120 automated hematology counter in detecting plasma cells through cytogram analysis, along with the significance of routine peripheral blood smear analysis and the utility of a large unstained cells (LUCs) threshold of > 4.5% as an indicator for PCL. The case involves a 64-year-old patient with relapsed multiple myeloma and stable paraprotein levels who experienced sudden renal impairment. In this case report, we highlight how ADVIA analysis and cytochemistry assisted in the diagnosis, and further explore ADVIA's utility in this challenging leukemia.

Necessity of flow cytometry assessment of circulating plasma cells and its connection with clinical characteristics of primary and secondary plasma cell leukaemia. Br J Haematol 2021; 195:95-107.

Abstract
Plasma cell leukaemia (PCL) is a rare and very aggressive plasma cell disorder. Preventing a dismal outcome of PCL requires early diagnosis with appropriate analytical tools. Therefore, the investigation of 33 patients with primary and secondary PCL was done when the quantity of circulating plasma cells (PCs) using flow cytometry (FC) and morphology assessment was evaluated. The phenotypic profile of the PCs was also analysed to determine if there is an association with clinical outcomes and to evaluate the prognostic value of analysed markers. Our results revealed that FC is an excellent method for identifying circulating PCs as a significantly higher number was identified by FC than by morphology (26·7% vs. 13·5%, P = 0·02). None of secondary PCL cases expressed CD19 or CD20. A low level of expression with similar positivity of CD27, CD28, CD81 and CD117 was found in both PCL groups. A decrease of CD44 expression was detected only in secondary PCL. Expression of CD56 was present in more than half of PCL cases as well as cytoplasmic nestin. A decreased level of platelets, Eastern Cooperative Oncology Group score of 2-3 and lack of CD20+ PC were associated with a higher risk of death. FC could be incorporated in PCL diagnostics not only to determine the number of circulating PCs, but also to assess their phenotype profile and this information should be useful in patients' diagnosis and possible prognosis.

Cancers (Basel) 2020; 12:E1499. [PMID: 32521788 PMCID: PMC7352573 DOI: 10.3390/cancers12061499] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2020] [Revised: 05/29/2020] [Accepted: 06/03/2020] [Indexed: 12/28/2022] Open
Abstract
Cancer dissemination and distant metastasis most frequently require the release of tumor cells into the blood circulation, both in solid tumors and most hematological malignancies, including plasma cell neoplasms. However, detection of blood circulating tumor cells in solid tumors and some hematological malignancies, such as the majority of mature/peripheral B-cell lymphomas and monoclonal gammopathies, has long been a challenge due to their very low frequency. In recent years, the availability of highly-sensitive and standardized methods for the detection of circulating tumor plasma cells (CTPC) in monoclonal gammopathies, e.g., next-generation flow cytometry (NGF), demonstrated the systematic presence of CTPC in blood in virtually every smoldering (SMM) and symptomatic multiple myeloma (MM) patient studied at diagnosis, and in the majority of patients with newly-diagnosed monoclonal gammopathies of undetermined significance (MGUS). These methods set the basis for further detailed characterization of CTPC vs. their bone marrow counterpart in monoclonal gammopathies, to investigate their role in the biology of the disease, and to confirm their strong impact on patient outcome when measured both at diagnosis and after initiating therapy. Here, we review the currently available techniques for the detection of CTPC, and determine their biological features, physiopathological role and clinical significance in patients diagnosed with distinct diagnostic categories of plasma cell neoplasms.

CD5+ B lymphoproliferative disorder with subsequent development of plasma cell leukaemia: Diagnostic and aetiologic reasoning. CYTOMETRY PART B-CLINICAL CYTOMETRY 2017; 94:688-694.

Abstract
BACKGROUND Plasma cell myeloma (PCM) has been sporadically reported to occur simultaneously or subsequently to mature B lymphoproliferative disorders (LPDs), predominantly chronic lymphocytic leukaemia (CLL). METHODS We describe the clinical and laboratory findings of a 69-year-old male patient who developed plasma cell leukaemia (PCL) 8 years after an initial diagnosis of a low stage CD5+ B LPD and 3 years after treatment for LPD. RESULTS The transition from a clinically indolent B LPD to an aggressive PCM was documented by bone marrow (BM) biopsy, while flow cytometric (FC) immunophenotyping conferred additional information by disclosing the co-existence of both disorders in BM and the presence of abnormal monotypic PCs in peripheral blood above PCL levels. Phenotypic findings suggested a discrete clonal origin of the two disorders. CONCLUSIONS This report of PCL development in a patient with residual CD5+ B LPD, emphasizes the need for comprehensive diagnostic evaluation of such cases and scrutiny of their aetiological relationship, including FC immunophenotyping due to its high analytical sensitivity and multiparametric capacity compared to morphology or immunohistochemistry alone. © 2017 International Clinical Cytometry Society.
