Plasma Cell Dyscrasias

AL amyloidosis is a systemic disease characterised by pathogenetic proteins produced by malignant plasma cells and the deposition of them in different organs of the body. Amyloidogenic protein is the light chain of the monoclonal immunoglobulin, which becomes water insoluble, precipitates and deposites in the extracellular space resulting damage of organ function. AL amyloidosis belongs to plasma cell dyscrasias or it can associate to other monoclonal B-cell diseases. Diagnosis – such as in case of other types of amyloidosis – is based on histology. Identification of the amyloidogenic protein often needs special examinations. The goal of the therapy is the eradication of the malignant cell clone. Therapeutical armamentarium has been largely flared in the past few decades, several drugs with new mechanisms of action are available (thalidomide, lenalidomide, bortezomib). The standard treatment is high dose chemotherapy followed by autologous stem cell transplantation in case of eligible patients. Transplantation uneligible patients can be treated with a low dose alkylating agent with or without dexamethasone, or with the new agents. The therapeutical decision must be preceded by very thorough risk assessment. Early diagnosis and the prompt beginning of the treatment has great significance because the evolving functional abnormalities of parenchymal organs (mainly cardiac failure) prevents the effectivity of the treatment. Amyloidosis is an orphan disease, special centers play a significant role in the field of clinical trials. Orv. Hetil., 2012, 153, 563–573.

Dose Methotrexate

Background: High-dose methotrexate (HDMTX) is likely to cause a number of side effects and manifest itself as hepatotoxicity, nephrotoxicity, mucositis, and neurotoxicity. A several studies demonstrated the efficacy of extracorporeal detoxification methods such as plasma exchange, hemodialysis (HD), HD filtration, and hemoperfusion for the treatment of MTX delayed clearance. However, none of the existing methods as effective as expected and limited for general implementation due to a procedure-related complication. Case Report: Here, we report a successful implementation of HA-230 hemoadsorption procedure to remove cumulated MTX from the body and reduce its toxicity in a child with ALL after high-dose chemotherapy. Results and Conclusion: Based on our results, single-hemoadsorption procedure with the HA-230 adsorber in case of delayed methotrexate clearance was safe and well-tolerated in a pediatric patient with ALL and would significantly improve the patient’s condition. Further studies need to demonstrate its safety and efficacy in a large number of pediatric patients.

Myeloma is a malignancy o f plasma cells which are terminally differentiated B-lymphocytes. The diagnosis may he made incidentally at routine blood testing, when an abnormality is found in the plasma proteins on electrophoresis. More usually the patients are symptomatic, with bone pain, anaemia, evidence o f renal failure, or the metabolic abnormalities associated with increased plasma calcium and urate levels. Effective treatment will extend survival from 7 to approximately 30 months and at the same time improve the quality o f life. Treatment is multidisciplinary, prominently involves the professional nurse and may arbitrarily be divided into two stages. Firstly, reversible lesions, such as dehydration and plasma hyperviscosity must be corrected, hypercalcaemia and hyperuricaemia improved and, if necessary, renal dialysis undertaken. Secondly, but o f equal importance, is the need for specific therapy to be directed against the tumour itself, and both cytotoxic agents and irradiation have an important role to play. More recently, newer approaches have included high dose chemotherapy and bone marrow transplantation.

Background: Multiple Myeloma (MM) represents approximately 15% of all hematological malignancies. Despite the use of high-dose chemotherapy followed by stem cell rescue MM remains incurable at present. The goal is to control the disease as much as possible, providing the best quality of life to patients for the longest duration. Currently, CTDa (attenuated Cyclophosphamide, Thalidomide, Dexamethasone) is the best option of treatment as it is cost-effective, with no need for hospitalization with a good response. Objective: To find out the symptomatic responses and toxicities of CTDa in Multiple Myeloma patients. Materials and Methods: 25 patients of newly diagnosed MM patients were treated in the Haematology Department, Bangabandhu Sheikh Mujib Medical University (BSMMU) from July 2016 to July 2017. The mean age of the patients was 54 years, Male female ratio was 1.5:1 and most of the patients were farmers. After induction of 4 to 6 cycles of CTDa all patients were followed up at 6th and 12th weeks. At follow up we evaluated improvement of weakness, bone pain, Hb%, ESR, monoclonal protein, ß2microglobulin, bone marrow plasma cells and serum calcium and albumin level. Adverse effects, such as peripheral neuropathy, thromboembolic events, hyperglycemia, constipation, rash, and somnolence were also assessed. Results: Among 25 patients, complete response achieved only 13 patients (52%), where 20% and 16% of patients belonged to partial or no response respectively. The death occurred in 2 cases (12%). Conclusion: CTDa is a gentle approach to treat an especially frail group of patients, since virtually all patients ultimately relapse. KYAMC Journal Vol. 11, No.-3, October 2020, Page 124-128

Abstract PTEN, a tumor suppressor gene, negatively regulates the anti-apoptotic action of akt phosphorylation. Allelic loss or mutation of this gene has been detected in many solid tumors and more recently in human myeloma cell lines (HMCLs). Expression of PTEN has resulted in growth inhibition and apoptosis of a HMCL, suggesting that it may play a role in the pathogenesis of multiple myeloma (MM). However, the PTEN status in tumor cells from patients with MM has not been determined. Using a triple staining method combining staining for cytoplasmic light chains and fluorescence in situ hybridization (FISH) with chromosome 10-centromere and PTEN-gene specific probes, we analyzed clonal plasma cells from 71 patients with MM, 10 with plasma cell leukemia (PCL) and 10 HMCLs. Hemizygous PTEN deletions were detected in 4 of 71 (5.6%) MM patients, 2 of 10 (20%) PCLs, and 2 of 10 (20%) HMCLs. The percentages of clonal plasma cells containing PTEN deletions ranged from 21–90% (median, 56%). Three of the 4 patients with PTEN deletions were detected at diagnosis with stage III disease (Duire-Salmon) and 1 was detected at relapse. Two patients had IgG kappa, 1 IgG lambda and 1 free lambda light chain. To correlate the PTEN status with other known genetic abnormalities in MM, we investigated 4 MM and 2 PCLs with PTEN deletions using FISH for chromosome13q, p53 status, translocations t(11;14), t(4;14) and t(14;16). One MM had a 13q deletion, 1 PCL had a t(11;14), and the other PCL had a t(14;16), a 13q deletion and a p53 deletion. All 4 MM patients with hemizygous PTEN deletions received melphalan based high-dose chemotherapy and autologous stem cell support. Their median overall survival (OS) was 48.1months, and progression free survival (PFS) was 42.8 months as compared to patients without PTEN deletions (OS, not reached, PFS, 25.8 months) (p=0.51 for OS, p=0.67 for PFS). Our results indicate that PTEN deletions are uncommon in MM patients and therefore unlikely represent a primary event for MM. PTEN deletions appear to occur in the advance stage of the disease, and are more frequently involved in PCL or HMCLs suggesting that deletions of PTEN may be associated with disease progression in a subset of MM.

Abstract Background: AL amyloidosis is generally caused by a kappa or lambda light-chain producing plasma cell clone in the bone marrow. High-dose melphalan (HDM) followed by autologous stem cell transplantation (ASCT) is effective in AL amyloidosis. Pretreatment of these patients with vincristine, doxorubicin and dexamethasone (VAD) may have a rapid and additive effect on the underlying plasma cell clone. Objective: To study the feasibility and efficacy of VAD followed by HDM and ASCT in AL amyloidosis. Patients and Methods: In a prospective multicenter phase II study, the Dutch-Belgian Hemato-Oncology Cooperative Group (HOVON) studied the effect of three courses of VAD followed by HDM with ASCT on hematological and clinical response rates and overall survival in AL amyloidosis. Untreated patients aged ≤ 65 years with proven AL amyloidosis and monoclonal gammopathy or multiple myeloma stage I were included. Patients with recent prior malignancy, other types of amyloidosis, and severe other diseases not related to AL amyloidosis were excluded. High risk was defined as cardiac septum ≥ 15 mm, cardiac ejection fraction ≤ 55%, creatinine > 177 μmol/L, or bilirubin > 34 μmol/L (Dispenzieri et al, J Clin Oncol2001; 19:3350–6). All patients were treated with VAD or dose-modified VAD and after the third course re-evaluated. Patients were judged eligible for stem cell collection and ASCT if WHO performance status 0–2, NYHA class 1–3, cardiac ejection fraction >45%, and no severe other disease. Hematological response was defined as complete response (disappearance of monoclonal protein in blood and urine, and no clonal excess of plasma cells in bone marrow), partial response (greater than 50% reduction in serum and urine monoclonal proteins), persistence, and progression (doubling of monoclonal protein in serum or urine). Clinical response was defined as organ response, stabilization, or progression (Gertz et al, Am J Hematol2005; 79:319–28). Results: Sixty-nine newly diagnosed patients with AL amyloidosis were included between September 2000 and January 2006: 37 men and 32 women with a median age of 55 years and WHO performance status 0–2. Organ involvement was renal in 58 (84%), cardiac in 32 (46%), hepatic in 12 (17%), and neuropathic in 18 (26%); 15 patients (22%) had involvement of 3 or 4 organs. Thirty-seven (54%) could be classified as high-risk patients. Forty-six patients (67%) could proceed to HDM (140–200 mg/m2) after VAD induction. The transplants were performed in tertiary referral centres. Median haematological recovery time of ANC > 1.0 × 109/L and platelets > 50 × 109/L was 17 and 21 days, respectively. End of survey was November 2007. Overall hematological response was 39% including 16% with a complete response. Overall clinical response was 26% and stabilization in 35%. In 43% of patients only the clinical response could be assessed. Overall survival of all patients was median 60 months and had not been reached for the transplanted patients (Figure). Nine patients died from TRM (11%), 7 during VAD and 2 following HDM. Side effects CTC grade ≥ 2 were recorded in 46% of patients during VAD induction and in 87% of patients after HDM; infections CTC grade ≥ 2 were recorded in 13% and 65%, respectively. Conclusions: VAD induction followed by HDM and ASCT for AL amyloidosis is feasible, has acceptable TRM, and results in a remarkable prolonged survival. This two-step approach of induction with non-intensive chemotherapy in all patients followed by HDM with ASCT in eligible patients is now recommended as standard treatment by HOVON for newly diagnosed patients with AL amyloidosis who are eligible for high-dose therapy.

High Dose Melphalan

Abstract Abstract 1350 Background: Systemic Primary AL Amyloidosis is a rare but potentially fatal disease resulting from tissue deposits of amyloid fibrils derived from monoclonal immunoglobulin light chains. High-dose melphalan followed by autologous hematopoietic stem cell transplant (auto HCT) is associated with hematologic and organ responses and improved survival. Methods: In this retrospective analysis we identified 46 patients with primary AL amyloidosis who received auto HCT between 01/1998 to 05/2010 at MDACC. Organ responses were determined using Amyloidosis Consensus Criteria. Results: The median age at auto HSCT was 56 years (34-74) where 61% were males and 35% were older than 60 years of age. 61% had lambda light chain restriction and only 4% had cytogenetic abnormalities. Disease characteristics are summarized in Table 1. The median time from diagnosis to auto HCT was 6.6 months (2.2-29.4 months). 22 pts (47.8%) had one organ, 19 pts (41.3%) had 2 organ and 4 pts (8.7%) had 3 organ involvement. 11 pts (23.9%) had heart and 35 pts (76.1%) had kidney involvement. The median follow up from the time of diagnosis was 22.4 months and from time of auto HCT was 16.7 months. High dose Melphalan dose was 200mg/m2 in 24 pts (52%) and 140mg/m2 in 22 (47.8%). There were 4 early deaths and 4 pts whose follow up was less than 3 months and their response was not assessed. Out of the 38 evaluable patients, the post-transplant organ responses were as follows ≥PR 25(66%), ≥stable disease 35(92%) (Table2). The hematologic responses were: CR=5 (13%), ≥VGPR=10(26%), ≥PR=26 (68%), ≥SD=37(97%). One patient had progressive disease. There was a correlation between organ response and hematologic response (chi square;p<10-3). The day-100 treatment related mortality (TRM) was 8.7% and 1-yr TRM was 13%. The median progression-free (PFS) and overall survival (OS) from auto HCT was 73.8 months and not reached (from transplant). The median PFS and OS from diagnosis were 93 months and 59.8 months respectively. In multivariate analysis, heart involvement (p=0.01), female sex (p=0.011), age ≥60 years (p=0.002), bone marrow plasma cells≥10% (p=0.043) and Beta-2 microglobulin>3.5mg/l (p=0.02) were associated with poor OS. Improved OS correlated with organ response (52.6 vs 11.4 months; p=0.01) and hematologic response (52.6 vs.6.1months; p=0.002). Hemoglobin <10 g/dl (p=0.047), bone marrow plasma cells≥10% (p=0.043) and age≥60 years (p=0.075) were associated with shorter PFS. Hematologc response (p=0.48) and organ response (p=0.12) were not associated with improved PFS. Conclusion: In this analysis the outcome of patients with primary systemic AL amyloidosis was durable with auto HCT with acceptable mortality risk and improved survival. Disclosures: No relevant conflicts of interest to declare.

Paraneoplastic Disorder

POEMS syndrome is a rare paraneoplastic disorder associated with an underlying plasma cell dyscrasia presenting polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and skin changes. This study reviewed the clinical characteristics of 14 POEMS patients in Zhongshan hospital. The ratio of male to female was 9 : 5, and the average age was 47.1 years. The clinical manifestations were various, including motorial symptoms (weakness), sensory symptoms (numbness), lymphadenopathy, edema, abdominal distention, and skin hyperpigmentation. Imaging studies and laboratory tests also exhibited hepatomegaly, splenomegaly, thrombocytosis, endocrinopathy, and positive serum immunofixation in most patients. In addition, increased plasma cells in bone marrow and Castleman Disease were found in bone marrow and lymph nodes biopsies. All the eight follow-up patients were treated with alkylator-based combination chemotherapy or corticosteroids and thalidomide, with or without autologous stem cell transplantation. Unfortunately, two patients died three or four years after diagnosis of POEMS syndrome. The others showed response to therapy to some extent, but not completely remission. Currently, treatments for POEMS include radiation to the plasmacytoma, and systemic therapy is indicated. Low-dose alkylators with or without corticosteroids are effective in some patients. However, high-dose chemotherapy with auto-SCT dramatically improved symptoms and outcomes for POEMS patients.

Common Manifestation

SummarySystemic amyloidosis is a life-threatening and frequently unrecognized cause of dysautonomia. Autonomic neuropathy is a common manifestation of AL amyloidosis (caused by deposition of an immunoglobulin free light chain produced by an underlying plasma cell clone) and of autosomal dominant hereditary ATTR amyloidosis (caused by a transthyretin mutation). The following review aims to alert clinicians to look out for signs and symptoms of amyloidosis to enable the bioptic diagnosis at an early stage. Suspicion of systemic amyloidosis is usually raised by the systemic, multi-organ character of the disease. An interdisciplinary approach is needed in the individual patient in order to establish the diagnosis and to obtain a clear overview of the actual multitude of organ problems. This overview is necessary for risk management and for making a well-considered treatment choice. Collaboration of all medical specialists involved is necessary to deliver optimal treatment and care to the patient with this systemic disease.

Genetic Events

Plasma cells (PC) are the main effectors of adaptive immunity, responsible for producing antibodies to defend the body against pathogens. They are the result of a complex highly regulated cell differentiation process, taking place in several anatomical locations and involving unique genetic events. Pathologically, PC can undergo tumorigenesis and cause a group of diseases known as plasma cell dyscrasias, including multiple myeloma (MM). MM is a severe disease with poor prognosis that is characterized by the accumulation of malignant PC within the bone marrow, as well as high clinical and molecular heterogeneity. MM patients frequently develop resistance to treatment, leading to relapse. Polycomb group (PcG) proteins are epigenetic regulators involved in cell fate and carcinogenesis. The emerging roles of PcG in PC differentiation and myelomagenesis position them as potential therapeutic targets in MM. Here, we focus on the roles of PcG proteins in normal and malignant plasma cells, as well as their therapeutic implications.
