Abstract
Simple Summary The growing interest in BCL2 inhibitors for the treatment of multiple myeloma (MM) has led to the need for biomarkers that are able to predict patient’s sensitivity to the drug. The presence of the chromosomal translocation t(11;14) in MM is mainly associated with sensitivity to venetoclax and good prognosis. The incidence of t(11;14) largely increases in primary Plasma Cell Leukemia (pPCL) in association with an unfavorable outcome. Currently, data concerning pPCL sensitivity to venetoclax are virtually absent. In this context, we investigated the transcriptome of MM and pPCL with t(11;14), evidencing that the two clinical entities are likely responsive to venetoclax based on different molecular programs, thus prompting further studies to elucidate better novel potential predictive biomarkers. Abstract Mechanisms underlying the pathophysiology of primary Plasma Cell Leukemia (pPCL) and intramedullary multiple myeloma (MM) need to be further elucidated, being potentially relevant for improving therapeutic approaches. In such a context, the MM and pPCL subgroups characterized by t(11;14) deserve a focused investigation, as the presence of the translocation is mainly associated with sensitivity to venetoclax. Herein, we investigated a proprietary cohort of MM and pPCL patients, focusing on the transcriptional signature of samples carrying t(11;14), whose incidence increases in pPCL in association with an unfavorable outcome. In addition, we evaluated the expression levels of the BCL2-gene family members and of a panel of B-cell genes recently reported to be associated with sensitivity to venetoclax in MM. Moreover, transcriptional analysis of lncRNAs in the two clinical settings led to the identification of several differentially expressed transcripts, among which the SNGH6 deregulated lncRNA might be relevant in the pathogenesis and prognosis of pPCL with t(11;14). Overall, our data suggest that MMs and pPCLs with t(11;14) might be responsive to venetoclax based on different molecular programs, prompting further studies to elucidate better novel potential predictive biomarkers.

Abstract
Plasma cell leukaemia (PCL) is one of the most aggressive and rarest forms of plasma cell dyscrasia. However, the diagnostic criteria for this condition have not yet been revised and there is no specific treatment to significantly improve the course of the disease. We report a 69-year-old male who presented to the Lok Nayak Hospital, New Delhi, India, in 2017 with dyspnoea and chest pain. A peripheral blood smear showed an absolute plasma cell count of 2.16 × 109/L. A bone marrow examination showed 61% atypical plasma cells exhibiting kappa light chain restriction. Biochemical investigations were consistent with a diagnosis of primary PCL with renal involvement. Bortezomib-based chemotherapy was initiated, which resulted in an improvement in the patient's haematological and biochemical parameters. This case report includes a comprehensive review of the clinical and diagnostic features, pathobiology and treatment of PCL.
