Abstract
Melphalan flufenamide (melflufen), a first-in-class alkylating peptide-drug conjugate, plus dexamethasone was approved in Europe for use in patients with triple-class refractory relapsed/refractory multiple myeloma (RRMM) with ≥3 prior lines of therapy and without prior autologous stem cell transplantation (ASCT) or with a time to progression >36 months after prior ASCT. The randomized LIGHTHOUSE study (NCT04649060) assessed melflufen plus daratumumab and dexamethasone (melflufen group) versus daratumumab in patients with RRMM with disease refractory to an immunomodulatory agent and a proteasome inhibitor or who had received ≥3 prior lines of therapy including an immunomodulatory agent and a proteasome inhibitor. A partial clinical hold issued by the US Food and Drug Administration for all melflufen studies led to financial constraints and premature study closure on February 23rd 2022 (data cut-off date). In total, 54 of 240 planned patients were randomized (melflufen group, N=27; daratumumab group, N=27). Median progression-free survival (PFS) was not reached in the melflufen group versus 4.9 months in the daratumumab group (Hazard Ratio: 0.18 [95% Confidence Interval, 0.05-0.65]; P=0.0032) at a median follow-up time of 7.1 and 6.6 months, respectively. Overall response rate (ORR) was 59% in the melflufen group versus 30% in the daratumumab group (P=0.0300). The most common grade ≥3 treatment-emergent adverse events in the melflufen group versus daratumumab group were neutropenia (50% vs. 12%), thrombocytopenia (50% vs. 8%), and anemia (32% vs. 19%). Melflufen plus daratumumab and dexamethasone demonstrated superior PFS and ORR versus daratumumab in RRMM and a safety profile comparable to previously published melflufen studies.

Abstract
Melphalan flufenamide (melflufen), a first-in-class, alkylating peptide-drug conjugate, demonstrated clinical benefit in combination with dexamethasone in triple-class refractory multiple myeloma (MM). The phase I/IIa ANCHOR study evaluated melflufen (30 or 40 mg) and dexamethasone (40 mg with daratumumab; 20 mg followed by 40 mg with bortezomib; dose reduced if aged ≥75 years) in triplet combination with daratumumab (16 mg/kg; daratumumab arm) or bortezomib (1.3 mg/m2; bortezomib arm) in patients with relapsed/refractory MM refractory to an immunomodulatory agent and/or a proteasome inhibitor and who had received one to four prior lines of therapy. Primary objectives were to determine the optimal dose of melflufen in triplet combination (phase I) and overall response rate (phase IIa). In total, 33 patients were treated in the daratumumab arm and 23 patients received therapy in the bortezomib arm. No dose-limiting toxicities were reported at either melflufen dose level with either combination. With both triplet regimens, the most common grade ≥3 treatment-emergent adverse events were thrombocytopenia and neutropenia; thrombocytopenia was the most common treatment-emergent adverse event leading to treatment discontinuation. In the daratumumab arm, patients receiving melflufen 30 mg remained on treatment longer than those receiving the 40-mg dose. In the daratumumab arm, the overall response rate was 73% and median progression-free survival was 12.9 months. Notably, in the bortezomib arm, the overall response rate was 78% and median progression-free survival was 14.7 months. Considering the totality of the data, melflufen 30 mg was established as the recommended dose for use with dexamethasone and daratumumab or bortezomib for future studies in relapsed/refractory MM.

Abstract
BACKGROUND Isoelectric focusing (IEF) is a method with an exquisite resolution, and coupled with affinity immunoblotting (AIB), it can provide superior sensitivity to detect monoclonal free light chains (FLC). METHODS We tested the hypothesis that IEF/AIB is more sensitive and specific for monoclonal FLC detection in serum and urine samples than conventional methods, that is, electrophoresis (ELP), immunofixation (IF) and serum FLC ratio assessment. Investigation included 107 samples of 68 patients, among which 21 multiple myeloma patients were recently tested for minimal residual disease and 18 patients with AL amyloidosis. RESULTS Monoclonal FLC were detected by IEF/AIB in 37% of serum samples negative for monoclonal FLC on ELP/IF. As for urine samples, significant advantage of the IEF/AIB over ELP/IF was not demonstrated. Considering both serum and urine results, IEF/AIB definitely revealed monoclonal FLC in 20/83 (24%) of ELP/IF-negative samples. FLC ratio was abnormally high (>1.65) in all 11 patients definitely positive for monoclonal FLC kappa by IEF/AIB but also in 16/47 (34%) IEF/AIB-negative samples. Abnormally low values (<0.26) were found only in 10/28 samples (36%) positive for monoclonal FLC lambda. Appropriate use of renal FLC ratio reference range reduced the number of presumably false positives (6/47, i.e. 13%) but not false negatives (17/28, i.e. 61%). CONCLUSIONS The IEF/AIB method is more sensitive than IF and might be used in patients with negative IF results before deciding whether to proceed to minimal residual disease testing.

Abstract
Monoclonal gammopathies are a group of blood diseases characterized by presence of abnormal immunoglobulins in peripheral blood and/or urine of patients. Multiple myeloma and plasma cell leukemia are monoclonal gammopathies with unclear etiology, caused by malignant transformation of bone marrow plasma cells. Mass spectrometry with matrix-assisted laser desorption/ionization and time-of-flight detection is commonly used for investigation of the peptidome and small proteome of blood plasma with high accuracy, robustness, and cost-effectivity. In addition, mass spectrometry coupled with advanced statistics can be used for molecular profiling, classification, and diagnosis of liquid biopsies and tissue specimens in various malignancies. Despite the fact there have been fully optimized protocols for mass spectrometry of normal blood plasma available for decades, in monoclonal gammopathy patients, the massive alterations of biophysical and biochemical parameters of peripheral blood plasma often limit the mass spectrometry measurements. In this paper, we present a new two-step extraction protocol and demonstrated the enhanced resolution and intensity (>50×) of mass spectra obtained from extracts of peripheral blood plasma from monoclonal gammopathy patients. When coupled with advanced statistics and machine learning, the mass spectra profiles enabled the direct identification, classification, and discrimination of multiple myeloma and plasma cell leukemia patients with high accuracy and precision. A model based on PLS-DA achieved the best performance with 71.5% accuracy (95% confidence interval, CI = 57.1-83.3%) when the 10× repeated 5-fold CV was performed. In summary, the two-step extraction protocol improved the analysis of monoclonal gammopathy peripheral blood plasma samples by mass spectrometry and provided a tool for addressing the complex molecular etiology of monoclonal gammopathies.

Abstract
BACKGROUND The TOURMALINE-MM4 trial demonstrated a significant and clinically meaningful progression-free survival (PFS) benefit with ixazomib versus placebo as postinduction maintenance in nontransplant, newly-diagnosed multiple myeloma patients, with a manageable and well-tolerated toxicity profile. MATERIALS AND METHODS In this subgroup analysis, efficacy and safety were assessed by age (< 65, 65-74, and ≥ 75 years) and frailty status (fit, intermediate-fit, and frail). RESULTS In this analysis, PFS benefit with ixazomib versus placebo was seen across age subgroups, including patients aged < 65 years (hazard ratio [HR], 0.576; 95% confidence interval [CI], 0.299-1.108; P = .095), 65-74 years (HR, 0.615; 95% CI, 0.467-0.810; P < .001), and ≥ 75 years (HR, 0.740; 95% CI, 0.537-1.019; P = .064). PFS benefit was also seen across frailty subgroups, including fit (HR, 0.530; 95% CI, 0.387-0.727; P < .001), intermediate-fit (HR, 0.746; 95% CI, 0.526-1.058; P = .098), and frail (HR, 0.733; 95% CI, 0.481-1.117; P = .147) patients. With ixazomib versus placebo, rates of grade ≥ 3 treatment-emergent adverse events (TEAEs; 28-44% vs. 10-36%), serious TEAEs (15-29% vs. 3-29%), and discontinuation due to TEAEs (7-19% vs. 5-11%) were higher or similar across age and frailty subgroups, and generally somewhat higher in older age groups and intermediate-fit/frail patients in both arms. Treatment with ixazomib versus placebo did not adversely affect patient-reported quality-of-life scores across age and frailty status subgroups. CONCLUSION Ixazomib is a feasible and effective maintenance option for prolonging PFS across this heterogeneous patient population.

Abstract
Idiopathic retroperitoneal fibrosis (IRF) is a rare condition characterized by the development of a peri-aortic and peri-iliac tissue showing chronic inflammatory infiltrates and pronounced fibrosis. Ureteral entrapment with consequent obstructive uropathy is one of the most common complications, which can lead to acute renal failure and, in the long term, to varying degrees of chronic kidney disease. Common symptoms at onset include lower back, abdominal or flank pain, and constitutional symptoms such as malaise, fever, and anorexia and weight loss. Pain is frequently referred to the hip, to the groin and to the lateral regions of the leg, with nocturnal exacerbations, and typically does not modify with position. We report a case of 56 year-old male with recurrent lower back pain and lower abdominal pain. Contrast-enhanced computed tomography and was suggestive of retroperitoneal fibrosis and unilateral ureteral occlusion. Histologic examination with immunohistochemical staining for IgG4 demonstrate IgG4-related retroperitoneal fibrosis. Therapy was started with prednison 1 mg/kg, but the tolerance of this dose was poor. Therefore the therapy was switched to combination of rituximab 375 mg/ m2 on day 1, cyclophosphamide 300 mg/m2 mg infusion and dexamethasone 20 mg total dose infusion on day 1 and 15 in 28 days cycle. FDG-PET/CT control in fourth month showed residual accumulation of FDG in retroperitoneal fibrotic mass, and therefore the therapy was prolonged to 8 month. The subjective symptoms of this diseases disappeared in the 8th month. Then the maintenance therapy, administration of rituximab in 6 month interval, was started. The activity of this disease be further evaluated by FDG-PET/CT imagination. Glucocorticoids are considered the cornerstone of therapy. The use of other immunosuppressive agents, including cyclophosphamide, azathioprine, methotrexate, mycophenolate mofetil and biological agents such as rituximab, tocilizumab and infliximab and sirolimus have been reported as a valuable option mostly in case reports, cases series and small studies. This agents allowed to reduce cumulative dose of glucocorticoids and its adverse effects. Therefore in our patients we preferred combination of rituximab cyclophosphamide s dexamethasone with lover dose of prednisonem. This combination is preferable for patients who cannot tolerate glucocorticoids or who are likely to suffer from significant glucocorticoids -related toxicity.

Abstract
BACKGROUND Waldenström macroglobulinemia (WM) is a lymphoplasmocytic lymphoma with immunoglobulin M monoclonal protein. The incidence of this disease is very low (0.4/100,000), so that this disease can be regarded as an orphan's disease. It means that new drugs are often tested and registered for more frequent diseases. PURPOSE In this review we will focus on the efficacy of the new drugs for WM. RESULTS The current treatment options for symptomatic WM patients include alkylating agent cyclophosphamide and anti-CD20 monoclonal antibodies. Therapy with rituximab and bendamustin resulted in longer therapeutic response then therapy with rituximab, cyclophosphamide and dexamethasone. Many drugs, used in multiple myeloma (MM), shoved promising results in WM patients. Bortezomib is effective in WM, but its neurotoxicity is higher in WM than in MM patients. Therefore, new proteasome inhibitors, carfilzomib and ixazomib, are better tolerated as documented in several studies. New types of antiCD20 antibody (obinutuzumab) can be used in patients with rituximab intolerance. in five of our patients with WM, obinutuzumab and bendamustin reached deeper responses than therapies administered in previous lines of therapy. Oral Bruton tyrosine kinase (BTK) inhibitor ibrutinib alone and in combination with rituximab have extended the treatment options for WM patients. New BTK inhibitors (e. g. acalabrutinib, zanubrutinib, and vecabrutinib) were tested and their lower toxicity (atrial fibrillation) was documented. Moreover, the BCL2 inhibitor venetoclax is newly tested. CONCLUSION New antiCD20 antibody (obinutuzumab) is of advantage in patients with WM with rituximab intolerance as well as bendamustin and new proteasome inhibitors (ixazomib and carfilzomib) or new BTK inhibitors with lower cardiotoxicity. Many of the abovementioned drugs do not have official registration for WM and can be administrated with the consent of the health care provider only. Thus, this work brings evidence of their efficacy.

Abstract
SAPHO is an acronym derived from capital letters of Synovitis, Acne, Pustulosis, Hyperostosis, and Osteitis (SAPHO). SAPHO syndrome is an umbrella term covering a constellation of bone lesions and skin manifestations. A 40-year-old male complained about his jaw and back pain, swelling of multiple joints and weight loss accompanied by physical deterioration and acne type skin lesions. Laboratory tests revealed abnormal elevation of inflammatory markers. Imaging studies illustrated multiple osteolytic bone lesions and paraosseal infiltrates. According to the set of criteria diagnosis of SAPHO syndrome was stated. The patient was treated with glucocorticoids and non-steroidal anti-inflammatory drugs (NSAIDs), but only high dose dexamethasone and prednisone were effective. Daily subcutaneous administration of anakinra at the dose of 100 mg was initiated due to limited response to more classical therapies. Because of planned mandibular osteosynthesis initiation of denosumab was preferred before bisphosphonates. Therapeutic response was confirmed by FDG-PET/MR after 5 months of anakinra and denosumab therapy, showing decreased accumulation of FDG in periosteal and paraosseal infiltrates. Inflammatory markers significantly decreased, bone pain deferred but skin manifestation receded only partially. Therefore the response was evaluated as partial remission.

Abstract
BACKGROUND Idiopathic multicentric Castleman disease (iMCD) is characterized by constitutional symptoms, enlarged lymph nodes and laboratory test abnormalities, which are primarily related to the overproduction of interleukin-6 (IL-6). This form (iMCD) was treated earlier with cytostatics used for lymphoma, later with bio-logic therapy as rituximab, immunodulatory drugs and proteasome inhibitors, and in the last years with an anti-IL-6 antibody, siltuximab. Siltuximab is a human-mouse chimeric immunoglobulin G1k monoclonal antibody against human IL-6 approved in the European Union for the treatment of iMCD. In view of the limited treatment options for iMCD, this case report aimed to evaluate the efficacy and safety of siltuximab in the management of this condition. CASE We describe a young woman with iMCD diagnosed at the age of 25 years. For first line treatment, rituximab and dexamethasone were used without any cytostatic because the patient wished to give birth to a healthy child in the future. However, the response after this first line therapy was short. In addition, after 3 years from the start of rituximab + dexamethasone therapy, it was necessary to administer treatment for the relapse of iMCD. We decided for siltuximab in this young woman, still aged < 30 years, and started administration of siltuximab in 3-week intervals. RESULTS After administration of first two infusions of siltuximab, all inflammatory markers returned to normal value. Moreover, serum hemoglobin and albumin levels as well as C-reactive protein normalized after the first two administrations of siltuximab. The clinical response continue, siltuximab is still administered in 3-week intervals. PET/CT with fluorodeoxyglucose confirmed a very good anatomic and metabolic response to the treatment. Siltuximab demonstrated a favorable safety profile, and the prolonged treatment was well tolerated. CONCLUSION This result is encouraging and demonstrates the potential of siltuximab as treatment of CD. As earlier published, this case confirms that significantly elevated inflammatory markers in a patient with CD predict a good response to siltuximab.

Abstract
We assessed the outcomes of pomalidomide and dexamethasone treatment in relapsed/refractory multiple myeloma (RRMM) patients with ≥1 prior line of therapy. We analyzed the data of all RRMM patients treated with pomalidomide and dexamethasone at nine Czech centers between 2013 and 2018. The source of the data was the Registry of Monoclonal Gammopathies of the Czech Republic. Primary endpoints included response rates based on International Myeloma Working Group criteria and survival measures, including progression-free survival (PFS) and overall survival (OS). Secondary endpoints were toxicities and previous treatment patterns, including refractory to lenalidomide, and their impact on final outcomes. The overall response rate was 51.8% and the clinical benefit rate (including patients with minimal response) was 67.1%, with 0.6% of complete responses, 8.5% of very good partial responses, and 42.1% of partial responses (PR). Overall, 16.5% of patients had a minimal response, and 32.3% had stable disease /progression. Median PFS was 8.8 months and the median OS was 14.2 months. In patients who achieved ≥PR, the median PFS and OS were significantly longer compared to non-responders (median PFS (12.1 vs. 4.5 months, p≤0.001 respectively), median OS (22.1 vs. 7.7 months, p≤0.001, respectively). The most frequent adverse events (AEs) were neutropenia (29.9%) and anemia (18.9%), non-hematological AEs included infections (14.6%) and fatigue (7.3%). Our analysis confirmed the effectiveness of pomalidomide and dexamethasone in a real-world setting. This therapy achieved reasonable outcomes comparable to the data from clinical trials even though this was an unbiased cohort of patients.

Abstract
Extramedullary multiple myeloma (EMD) is an aggressive disease; malignant plasma cells lose their dependence in the bone marrow microenvironment and migrate into tissues. EMD is a negative prognostic factor of survival. Using flow cytometry and next-generation sequencing, we aimed to identify antigens and microRNAs (miRNAs) involved in EMD pathogenesis. Flow cytometry analysis revealed significant differences in the level of clonal plasma cells between MM and EMD patients, while the expression of CD markers was comparable between these two groups. Further, miR-26a-5p and miR-30e-5p were found to be significantly down-regulated in EMD compared to MM. Based on the expression of miR-26a-5p, we were able to distinguish these two groups of patients with high sensitivity and specificity. In addition, the involvement of deregulated miRNAs in cell cycle regulation, ubiquitin-mediated proteolysis and signaling pathways associated with infections or neurological disorders was observed using GO and KEGG pathways enrichment analysis. Subsequently, a correlation between the expression of analyzed miRNAs and the levels of CD molecules was observed. Finally, clinicopathological characteristics as well as CD antigens associated with the prognosis of MM and EMD patients were identified. Altogether, we identified several molecules possibly involved in the transformation of MM into EMD.

Abstract
BACKGROUND Rosai-Dorfman-Destombes disease (RDD) is a rare histiocytosis characterized by accumulation of activated histiocytes within affected tissues. Although the immunophenotype of this disease was described, the pathophysiology of this disease is still not sufficiently understood. Recent studies have found NRAS, KRAS, MAP2K1, and ARAF mutations in RDD lesions, raising the possibility of a clonal origin in some forms of RDD while in other cases reactive origin or association with other malignant and autoimmune disease is supposed. RDD is a widely heterogeneous entity with a range of clinical phenotypes occurring in some patients in association with autoimmune or malignant diseases. Its therapy should reflect the localization of the disease. Monotherapy with glucocorticoids is sufficient only in limited disease. In patients with advanced disease, combined nodal and extranodal forms of RDD need more intensive therapy. In older publications, antimetabolites, vinca alkaloids and prednisone were used; in recent publications, remissions after cladribine, rituximab, sirolimus, thalidomide, lenalidomide and cobimetinib were described. PURPOSE This text summarizes current knowledge about this rare disease and reviews the therapeutic options.

Abstract
Langerhans cell histiocytosis (LCH) is a rare condition with incidence in adults 1-2/1 million, wherein Langerhans cells proliferate abnormally, adversely impacting organs including most frequently bones, skin, lungs, pituitary gland, lymph nodes, gums and other organs. The LCH course varies widely among patients from a self-limiting condition, to one that progresses. But LCH only very rarely culminates in death. To aim of this text is to review all possible symptoms and manifestations of this disease.

Abstract
BACKGROUND Lenalidomid ranks among immunomodulatory drugs. There are a few of the more common side effects, like a higher risk of venous trombembolism or diarrhea. Other side effects are rare. The hyperbilirubinemia described in this article can be assigned to them. In our case, the increase of bilirubin was associated with unrecognized Gilbert syndrome. CASE DESCRIPTION We report a patient with multiple myeloma and necrobio-tic xanthogranuloma (NXG) of the skin and liver. After the treatment with bortezomib, lenalidomid and dexamethasone, complete remission was attained after 4 cycles with decrease of monoclonal immunoglobulin to an unmeasurable concentration. At the same time, the dis-appearance of cutaneous and hepatic lesions of NXG on FDG-PET/CT was evident. The administration of bortezomib was stopped after 8 cycles and only continued with lenalidomide as a maintenance therapy. However, after four cycles of this therapy, bilirubin increased above the upper limit and the increase continued till the 11th month of lenadomide administration, when bilirubin reached the highest concentration of 75 μmol/l (more than the three-fold of the upper limit, grade III toxicity). The patient had asymptomatic hyperbilirubinemia with no underlying liver disease or renal impairment while being on lenalidomide therapy. Genetic studies proved mutation; insertion in the promotor gene UGT1A1 typical for Gilbert syndrome. Hyperbilirubinemia may be attributed to the unmasking of previously undia-gnosed Gilbert syndrome. Therefore, the therapy with lenalidomide was interrupted after 11 months. The bilirubin level decreased after the discontinuation of the drug. CONCLUSION NXG disappeared after fulfilling complete remission of multiple myeloma with disappearance of monoclonal immunoglobulin. This observation supports the hypothesis that monoclonal immunoglobulin has a crucial role in the ethiopathogenesis of NXG and suggests the treatment of monoclonal gammopathy if present in a patient with NXG, hoping that this will result in xantogranuloma disappearance.

Abstract
Immunoglobulin IgG4 related disease (IgG4-RD) is a heterogeneous disorder with multi-organ involvement recognised as a separate entity at the beginning of this century only. Evolving therapy is reviewed in this paper. Glucocorticoids are first choice drug but long administration of glucocorticoids is connected with many adverse effects. In case of combination glucocorticoids and immunosuppressive agents lower doses of glucocorticoids are needed, the response rate is higher and therapy is better tolerated. Rituximab is drug, that is possible use as monotherapy or in combination with glucocorticoids and immunosuppressive drugs. Only one study compared two immunosuporessive drugs, mycophenolate mofetil and cyclophosphamide. The response rated was similar but remissions were longer after glucocorticoids with cyclophosphamide then glucocorticoids with mycofenolat mofetil. No other comparative study of combination of various imunossupressive drugs with glucocorticoids was published. Rituximab has high number (90 %) of response rate in monotherapy, but can be used in combination with glucocorticoids and immunosuppressives. Rituximab is now preferred and recommended for maintenance therapy administered in 6-month interval. In case of advanced disease, we prefer therefore combination of rituximab, cyclofosphamide and dexamethasone for initial therapy followed by maintenance with rituximab in 6 months interval. There are two new drugs under investigation abatacept and dupilimab with promising results. Although we have very intensive therapies for good results of therapy early diagnosis before irreversible fibrotic changes in IgG4-RD involved organs is still needed.

Abstract
Castleman disease (CD) describes a group of heterogeneous hematologic disorders with characteristic histopathological features. CD can present with unicentric (UCD) or multicentric (MCD) regions of lymph node enlargement. Some cases of MCD are caused by human herpesvirus-8 (HHV-8), whereas others are HHV-8-negative/idiopathic (iMCD). Treatment of iMCD is challenging, and outcomes can be poor. In this paper, we briefly report about symptoms of iMCD and about the International, evidencebased consensus diagnostic criteria for HHV-8-negative/idiopathic multicentric Castleman disease and International evidence based consensus treatment guidelines for idiopathic multicentric Castleman disease.

Abstract
Idiopathic retroperitoneal fibrosis (IRF) is a rare condition characterized by the development of a peri-aortic and peri-iliac tissue showing chronic inflammatory infiltrates and pronounced fibrosis. Ureteral entrapment with consequent obstructive uropathy is one of the most common complications which can lead to acute renal failure and, in the long term, to varying degrees of chronic kidney disease. Common symptoms at onset include lower back, abdominal or flank pain. Pain is frequently referred to the hip, to the groin and to the lateral regions of the leg, often with nocturnal exacerbations and not responding to position changes. The disease is commonly associated with signs of systemic inflammatory response (malaise, fever, and anorexia and weight loss). Glucocorticoids are considered the cornerstone of the therapy. The use of other immunosuppressive agents, including cyclophosphamide, azathioprine, methotrexate, mycophenolate mofetil and biological agents such as rituximab, tocilizumab and infliximab have been reported as a valuable option mostly in case reports, cases series and small studies. These agents allowed to reduce cumulative dose of glucocorticoids and their adverse effects. Combined therapy is preferable for all patients who suffer from significant glucocorticoid- related toxicity or in cases where glucocorticoids alone are insufficient to treat the condition.

Abstract
Immunoglobulin G4- related disease (IgG4-RD) is a rare systemic fibro-inflammatory disorder. Autoimmune pancreatitis is the most frequent manifestation of IgG4-RD. However, IgG4-RD can affect any organ such as salivary glands, orbits, retroperitoneum, prostate and many others. Recent research enabled a clear clinical and histopathological description of IgG4-RD and in 2019 four Clinical phenotypes of IgG4-related disease were described. Diagnosis is based on morphological examination with typical findings of lymphoplasmocellular inflammation, storiform fibrosis and obliterative phlebitis in IgG4-RD biopsies and the tissue invading plasma cells largely produce IgG4. Elevated serum IgG4 levels are found in many but not all patients. New diagnostic criteria for IgG4-RD have been published recently in 2019 and 2021. This review summarizes current knowledge on pathophysiology, clinical manifestations, diagnosis and differential diagnosis of IgG4-RD from the point of view 2022 and in next article brings overview of the IgG4-RD therapy.

Abstract
Background COVID-19 disease caused by SARS-CoV-2 coronavirus has affected millions of people worldwide. The mortality of this infection varies with age and comorbidities up to more than 10% in very elderly population. The aim of our study was to determine the disease pattern and mortality rate among multiple myeloma patients. Methods We retrospectively analyzed entries in the Czech Registry of Monoclonal Gammopathies from patients who were infected with SARS-CoV-2 from March 2020 until May 2021. Demographic data, treatment patterns, comorbidities, symptoms of COVID-19, treatment modalities and healthcare utilization was compared in survivors and non-survivors. Results Overall, 371 patients with MM and COVID-19 infection were identified. Median age at covid-19 diagnosis was 69 years (37-91 years), 53.4% (198/371) were males. There were 70.1% (260/371) survivors and 20.8% (77/371) deceased patients, outcome of 9.2% (34/371) of patients is unknown. PCR positivity was seen with median 20 days (1-84 days) in 79 evaluable patients. 6 patients were vaccinated prior to infection (5-68 days). Infection was acquired during actual treatment in 53.1% of patients (197/371). Median number of previous lines administered was 1 (0-7). Treatment preceding infection was most frequently composed of lenalidomide in 50.3%, bortezomib in 42.1% and daratumumab in 19.8%. Symptomatic infection was seen in 74.9% (278/371) of patients with fever being the leading symptom (49.6%) followed by cough (39.1%) and shortness of breath (35.0%). Inpatient treatment was needed in 45.0% (167/371) of patients, intensive care unit was required in 38.9% (65/167) of patients. Median length of in-hospital stay was 11 days (1-53 days). Artificial lung ventilation was necessary in 10.8% (18/167) patients, 24.6% (41/167) needed non-invasive ventilation or high flow oxygen and 35.3% (59/167) of patients needed low flow oxygen. Remdesivir was administered to 10.0% (37/371) and convalescent plasma to 4.9% (18/371) of patients. No difference was seen in mortality according to ISS stage (p=0.609), administered lines of therapy (p=0.119) or achieved treatment response (p=0.418). Conclusions The mortality of MM patients with COVID-19 was very high (20.8%). Healthcare utilization was high with almost half of the infected myeloma patients needing inpatient treatment. No apparent risk factors in terms of disease status or previous treatment were identified. Supported by MH CZ - DRO (UHHK, 00169906) and by the program PROGRES Q40/8.

Abstract
OBJECTIVES This study compared the use of bortezomib in different combination regimens in newly diagnosed multiple myeloma (NDMM) patients who were transplant ineligible. PATIENTS AND METHODS We analyzed data from the Registry of Monoclonal Gammopathies (RMG) of the Czech Myeloma Group (CMG) to provide real-world evidence of outcome for 794 newly diagnosed MM transplant ineligible patients. The most frequently used regimen was VCd (bortezomib-cyclophosphamide-dexamethasone) (47.5%) over VMP (bortezomib-melphalan-prednisone) (21.7%), BDd (bortezomib-doxorubicin-dexamethasone) (9.8%), and VTd (bortezomib-thalidomide-dexamethasone) (2.9%). RESULTS The overall response rate (ORR) was 69.2% (478/691), including 12.6% (≥ CR); 34.7% very good partial responses (VGPR); and 21.9% partial responses (PR). Among triplet regimens, VMP was the most effective regimen compared to VCd, BDd, and VTd. Median PFS was 22.3 vs. 18.5 vs. 13.7 vs. 13.8 mo, (P = .275), respectively, and median OS was 49 vs. 41.7 vs. 37.9 vs. 32.2 mo (P = .004), respectively. The most common grade 3-4 toxicities were anemia in 17.4% and infections in 18% of patients. CONCLUSION Our study confirmed that bortezomib-based treatment is effective and safe in NDMM transplant ineligible patients, especially VMP, which was identified as superior between bortezomib-based induction regimens not only in clinical trials, but also in real clinical practice.

Abstract
PURPOSE The double-blind, placebo-controlled, phase III TOURMALINE-MM1 study demonstrated a statistically significant improvement in progression-free survival with ixazomib-lenalidomide-dexamethasone (ixazomib-Rd) versus placebo-Rd in patients with relapsed or refractory multiple myeloma. We report the final analyses for overall survival (OS). PATIENTS AND METHODS Patients were randomly assigned to ixazomib-Rd (n = 360) or placebo-Rd (n = 362), stratified by number of prior therapies (1 v 2 or 3), previous proteasome inhibitor (PI) exposure (yes v no), and International Staging System disease stage (I or II v III). OS (intent-to-treat population) was a key secondary end point. RESULTS With a median follow-up of 85 months, median OS with ixazomib-Rd versus placebo-Rd was 53.6 versus 51.6 months (hazard ratio, 0.939; P = .495). Lower hazard ratios, indicating larger magnitude of OS benefit with ixazomib-Rd versus placebo-Rd, were seen in predefined subgroups: refractory to any (0.794) or last (0.742) treatment line; age > 65-75 years (0.757); International Staging System stage III (0.779); 2/3 prior therapies (0.845); high-risk cytogenetics (0.870); and high-risk cytogenetics and/or 1q21 amplification (0.862). Following ixazomib-Rd versus placebo-Rd, 71.7% versus 69.9% of patients received ≥ 1 anticancer therapy, of whom 24.7% versus 33.9% received daratumumab and 71.8% versus 76.9% received PIs (next-line therapy: 47.5% v 55.8%). Rates of new primary malignancies were similar with ixazomib-Rd (10.3%) and placebo-Rd (11.9%). There were no new or additional safety concerns. CONCLUSION Median OS values in both arms were the longest reported in phase III studies of Rd-based triplets in relapsed or refractory multiple myeloma at the time of this analysis; progression-free survival benefit with ixazomib-Rd versus placebo-Rd did not translate into a statistically significant OS benefit on intent-to-treat analysis. OS benefit was greater in subgroups with adverse prognostic factors. OS interpretation was confounded by imbalances in subsequent therapies received, especially PIs and daratumumab.

Abstract
8037 Background: Development of resistance to standard treatments for RRMM highlights the need for novel therapies. Melphalan flufenamide (melflufen) is a first-in-class peptide-drug conjugate (PDC) that leverages aminopeptidases and rapidly releases alkylating agents inside tumor cells. Melflufen + dex showed clinical activity and an acceptable safety profile in HORIZON (Richardson et al. J Clin Oncol. 2020 Dec 9 [Epub]). This is an update of the BTZ arm of the phase 1/2a ANCHOR study (NCT03481556). Methods: Patients (pts) with RRMM were intolerant or refractory to a prior IMiD, with 1-4 prior lines of therapy (LoTs). Prior treatment with a proteasome inhibitor (PI) was allowed, but pts could not be refractory to PIs in the last LoT. Melflufen (30, 40, or 20 mg intravenously; d 1 of each 28-d cycle) was administered with BTZ (1.3 mg/m2 subcutaneous) + oral dex (20 mg on d 1, 4, 8, and 11 and 40 mg on d 15 and 22; dex dose reduced if aged ≥ 75 y). The primary objective in phase 1 was to determine the optimal phase 2 dose of melflufen for this combination. Results: As of the data cutoff date (October 19, 2020), 13 pts received melflufen (30 mg, n = 6; 40 mg, n = 7) + dex and BTZ. In the 30 mg and 40 mg cohorts, respectively, median age was 78.5 y (range, 70-82) and 70.0 y (range, 61-76); median prior LoTs was 3.5 (range, 2-4) and 2.0 (range, 1-4); 33% and 50% of evaluable pts had high-risk cytogenetics; 83% and 71% were refractory to last LoT; 100% and 86% received a prior PI; 33% and 14% were refractory to PIs. In the 30 mg and 40 mg cohorts, respectively, median treatment duration was 6.5 mo (range, 1.4-29.0) and 8.7 mo (range, 2.1-19.6); 4 (67%) and 4 pts (57%) were still on treatment; 2 and 3 pts discontinued (30 mg: progressive disease [PD] and other [1 pt each]; 40 mg: adverse event [AE], lack of efficacy, and PD [1 pt each]). Confirmed overall response rate in the 30 mg and 40 mg cohorts, respectively, was 50% (1 very good partial response [VGPR] and 2 partial response [PR]) and 71% (1 complete response, 3 VGPR, and 1 PR). Most common grade 3/4 treatment-related AEs (TRAEs) were thrombocytopenia (30 mg: 50%; 40 mg: 100%) and neutropenia (30 mg: 33%; 40 mg: 71%); grade 3/4 nonhematologic TRAEs were infrequent; 3 pts discontinued study treatment due to treatment-emergent AEs (30 mg: cardiac failure chronic and osteolysis [1 pt each]; 40 mg: thrombocytopenia [1 pt]). Serious TRAEs occurred in 2 pts (33%) in the 30 mg cohort (neutropenia and pneumonia [1 pt], syncope [1 pt]) and 1 pt (14%) in the 40 mg cohort (thrombocytopenia and neutropenia). No dose-limiting toxicities occurred at either dose level. Fatal AEs occurred in 1 pt in the 30 mg cohort (cardiac failure chronic; unrelated to study treatment). Conclusions: ANCHOR determined that the optimal dose of melflufen is 30 mg + dex and BTZ; results showed clinical activity in heavily pretreated pts. Recruitment is ongoing; updated data will be presented. Clinical trial information: NCT03481556.

Abstract
TPS8051 Background: Melphalan flufenamide (melflufen) is a first-in-class peptide-drug conjugate (PDC) that leverages aminopeptidases and rapidly releases alkylating agents inside tumor cells. Melflufen + dex showed clinical efficacy and was well tolerated in pts with heavily pretreated RRMM (HORIZON; Richardson et al. J Clin Oncol. 2020 Dec 9 [Epub]). The ongoing phase 1/2 ANCHOR study (OP-104) established the optimal dose for melflufen + dex and dara, showing meaningful clinical activity and manageable safety at both melflufen doses tested in pts with RRMM (Ocio et al. ASH 2020. Oral 417). The aim of this study (OP-108; NCT04649060) is to evaluate the efficacy and safety of melflufen + dex and dara vs dara in pts with RRMM previously treated with an IMiD and a proteasome inhibitor (PI), similar to the indication for dara monotherapy. Methods: Pt enrollment has begun (N = 240 planned). Pts must be ≥ 18 y, double refractory to (or intolerant of) an IMiD and a PI or had ≥ 3 prior lines of therapy (LoTs) including an IMiD and a PI, have measurable disease, and Eastern Cooperative Oncology Group performance status ≤ 2. Pts with primary refractory disease and refractoriness to an anti-CD38 antibody are excluded. Pts will be randomized 1:1 to open-label melflufen + dex and dara (Arm A) or single-agent dara (Arm B) until progressive disease [PD] or unacceptable toxicity, stratified by prior LoT number. Pts in Arm B with PD can opt to receive Arm A triplet therapy. Arm A: melflufen 30 mg intravenously on d 1 of each 28-d cycle; dex 40 mg/wk orally (20 mg if aged ≥ 75 y); dara 1800 mg subcutaneously on d 1, 8, 15, and 22 of cycle 1 and 2, d 1 and 15 of cycles 3-6, and d 1 of cycles 7+. Arm B: dara at the same dosage as Arm A. Primary objective: superiority ( P value from the 2-sided statistical test < 0.05; upper limit of the 2-sided 95% CI for the hazard ratio < 1) of progression-free survival (PFS) in pts treated with triplet therapy vs dara. An estimated sample of 240 pts with 160 expected events (PD or death) and 15% assumed dropout rate would provide 90% power at a 2-sided log rank test at 5% significance level to detect a hazard ratio for death of 0.6. Key secondary endpoints: overall response rate (ORR; ≥ partial response [PR]), duration of response, and safety. Response will be assessed by a blinded independent review committee based on International Myeloma Working Group criteria. Other secondary endpoints: clinical benefit rate (≥ minimal response), time to response, time to progression, time to next treatment, and overall survival. Exploratory endpoints include: minimal residual disease in pts achieving ≥ very good PR, PFS following next line of treatment (PFS-2), pt-reported outcomes, pharmacokinetics, translational biomarkers, response rate in pts with extramedullary disease, and efficacy (including ORR) in Arm B pts who receive Arm A triplet therapy after PD. Clinical trial information: NCT04649060.

Abstract
8019 Background: Multiple myeloma (MM) typically affects older populations, which are more vulnerable to toxicity with anti-MM treatments. These patients (pts) have significant morbidity and mortality, resulting in a need for dose modifications or alternative suboptimal treatment options. Significant improvements were observed in the BOSTON study with XVd vs Vd in median progression-free survival (PFS), overall response rate (ORR), and rates of peripheral neuropathy (PN); median overall survival (OS) trended in favor of XVd. Methods: The phase 3 randomized BOSTON trial (NCT03110562) is a controlled, open-label study of once weekly XVd vs. twice weekly standard Vd in pts with MM and 1-3 prior treatment regimens. We performed post-hoc analyses to compare survival benefits in pts ≥65 vs < 65 years of age. Results: The BOSTON study enrolled a total of 402 pts between June 2017 and February 2019 that were randomized into XVd or Vd arms. The numbers of pts treated with XVd or Vd who were ≥65 were 109/132 and 86/75 who were < 65, respectively. Baseline characteristics were similar by age although pts ≥65 years were less likely to have received ASCT than those < 65 years (48.4% vs. 25.3%). Median PFS was prolonged with XVd compared with Vd, across both age groups: ≥65 (HR, 0.55 [95% CI, 0.37-0.83] P = 0.002) and < 65, (HR, 0. 74 [95% CI, 0.49-1.11], P = 0.07). Vd was associated with a lower ORR (64.4%) than treatment with XVd (76.1%) (OR, 1.77 [95% CI, 1.00-3.11], P = 0.024) in pts ≥65, while the ORR in those < 65 was 76.7% with XVd and 58.7% (OR, 2.33 [95% CI, 1.18-4.59], P = 0.007) with Vd. As of Jan 2021, the median OS for the overall population was not reached for both arms (HR = 0.86; p = 0.193), with 61 and 75 deaths in the XVd and Vd arms, respectively. Median OS was not reached in pts ≥65 with XVd and was 28.6 months with Vd (HR = 0.60; 95% CI, 0.38-0.94; p = 0.012), while there was no difference in the OS for pts < 65 (HR = 1.52; 95% CI, 0.86-2.68; p = 0.926). Pts ≥65 had a lower incidence of death with XVd as compared to Vd (29 vs 56) and there were 32 deaths with XVd and 19 with Vd in pts < 65. Grade ≥3 treatment-emergent adverse events were not observed more often in older compared to younger pts. Amongst pts ≥65, PN of any grade was lower with XVd (32.1%) compared to Vd (46.5%); (OR 0.57 [95% CI 0.34-0.97], p = 0.017), including a lower incidence of grade ≥3 PN (XVd 4.6% vs. Vd 11.6%). Pts < 65 followed a similar trend of PN AEs of any grade: XVd, 32.6%; Vd, 48.0% (OR 0.42 [95% CI 0.21-0.82], p = 0.006). Conclusions: In an older patient population with a poor prognosis, XVd was associated with a significant survival benefit, improved PFS and OR with reduced PN, and requires relatively short and infrequent clinic visits. XVd may be a simple, effective regimen for pts ≥65 years of age. Clinical trial information: NCT03110562.

Abstract
8024 Background: Lenalidomide (LEN) is typically a frontline therapy for newly diagnosed MM. Patients (pts) with MM refractory to LEN are less likely to repond to other IMiDs and represent a signification area of unmet medical need. In the BOSTON study in the ITT population, XVd was associated with significant improvements in median progression-free survival (PFS), overall response rate (ORR), and rates of peripheral neuropathy, with trends in overall survival (OS) favoring XVd. Methods: The BOSTON trial (NCT03110562) is a Phase 3 randomized, controlled, open-label study of once weekly XVd vs twice weekly Vd in pts with MM and 1-3 prior therapies. We performed post-hoc analyses on two different subgroups to compare outcomes based on refractory status to LEN and immunomodulatory drug (IMiD) therapy. These post hoc analyses evaluated if PFS, overall response rate (ORR), time to next treatment (TTNT) and safety was influenced by prior treatment with LEN when comparing XVd with Vd. Results: Amongst the 402 pts in BOSTON, 160 had MM refractory to any IMiD (XVd = 74, Vd = 86). Of those, 106 were documented to be refractory to LEN (XVd = 53, Vd = 53) and 296 were not refractory to LEN (XVd = 142, Vd = 154). Baseline characteristics were generally well balanced between subgroups. In these subgroups based on refractory status to IMiD or LEN, median PFS was significantly longer in the XVd arm as compared to Vd (IMiD refractory, 13.9 vs. 8.4 months (mo), p = 0.005; LEN refractory, 10.2 vs. 7.1 mo, p = 0.012; not LEN refractory, 15.4 vs 9.6 mo, p = 0.014). Significant increases in TTNT were observed with XVd treatment in pts that were IMiD refractory (14.8 vs. 10.2 mo, p = 0.003), LEN refractory (13.0 vs. 7.6 mo, p = 0.015), and not refractory to LEN (19.1 vs 12.9 mo, p = 0.005). ORR was improved with XVd compared to Vd regardless of refractory status (IMiD refractory, 68.9% vs 55.8%, p = 0.045; LEN refractory, 67.9% vs. 47.2%, p = 0.016; and not refractory to LEN, 79.6% vs 67.5%, p = 0.010). The most common treatment-emergent AEs for the XVd/Vd arms for all subgroups were thrombocytopenia (66.2/30.6%; 71.7/40.4%; 55.6/22.4%), nausea (48.6/11.8%; 50.9/11.5%; 50.0/9.2%), and fatigue (40.5/20.0%; 45.3/21.2%; 40.8/17.1%) for IMiD, LEN, and not LEN refractory, respectively. Incidence of PN AEs of any grade were reduced compared to pts treated with Vd (IMiD refractory, 27% vs. 42.4%; LEN refractory, 30.2% vs 36.5%; not refractory, LEN 33.1% vs 50.7%). Conclusions: In pts with previously treated MM, PFS, ORR, and TTNT were significantly improved regardless of documented refractory status to any IMiD or to LEN-specifically. These analyses support the use of the XVd combination for pts with disease refractory to LEN and likely to any IMiD. Clinical trial information: NCT03110562.

Abstract
Aim: To evaluate the effectiveness and safety of ixazomib-lenalidomide-dexamethasone (IRd) in relapsed/refractory multiple myeloma in routine clinical practice. Patients & methods: Patient-level data from the global, observational INSIGHT MM and the Czech Registry of Monoclonal Gammopathies were integrated and analyzed. Results: At data cut-off, 263 patients from 13 countries were included. Median time from diagnosis to start of IRd was 35.8 months; median duration of follow-up was 14.8 months. Overall response rate was 73%, median progression-free survival, 21.2 months and time-to-next therapy, 33.0 months. Ixazomib/lenalidomide dose reductions were required in 17%/36% of patients; 32%/30% of patients discontinued ixazomib/lenalidomide due to adverse events. Conclusion: The effectiveness and safety of IRd in routine clinical practice are comparable to those reported in TOURMALINE-MM1. Clinical trial registration: NCT02761187 (ClinicalTrials.gov).

Abstract
Necrobiotic xanthogranuloma (NXG) is a rare chronic condition, belonging to the group non-Langerhans cell histiocytoses, which is relevant due to the possibility of extracutaneous involvement and association with systemic diseases, particularly monoclonal gammopathy, MGUS and multiple myeloma. The case reported here NXG was diagnosed after 1 years of evolution in patient with asymptomatic multiple myeloma. After treatment with bortezomib, lenalidomid and dexamethasone, there was evident abrupt decrease of monoclonal immunoglobulin to not measurable level (complete remission of multiple myeloma) and in the same time was evident disappearance of cutaneous and hepatic lesions of NXG on FDG-PET/CT. The etiopathogenetic association of monoclonal immunoglobulin with NXG is documented in this case report with disappearance of NXG in the time of disappearance of monoclonal immunoglobulin.

Abstract
Hereditary hemorrhagic telangiectasia (HHT), also known as Osler-Weber-Rendu syndrome, is an autosomal dominant disorder that causes abnormal blood vessel formation. Patients with HHT may have telangiectasias and later may develop arteriovenous malformations in various organs. Pacients suffer from many complications caused by the malformations and therefore by patients with HHT must by performed screening of this arteriovenous malformations. Optimal treatment of this malformations is best delivered throught a multidisciplinary approach. Farmacological treatment is described in next paper.

Abstract
Castleman disease (CD) includes a group of rare and heterogeneous disorders with characteristic lymph node histopathological abnormalities. CD can occur in a single lymph node station, which is referred to as unicentric CD (UCD). CD can also involve multicentric lymphadenopathy and inflammatory symptoms - multicentric Castleman disease. The first-ever diagnostic and treatment guidelines were recently developed for UCD and published 2020. Complete surgical resection is often curative and is therefore the preferred first-line therapy, if possible. The management of unresectable UCD is more challenging. Existing evidence supports that asymptomatic unresectable UCD may be observed. The anti-interleukin-6 monoclonal antibody siltuximab should be considered for unresectable UCD patients with an inflammatory syndrome. Unresectable UCD that is symptomatic because of compression of vital neighbouring structures may be rendered amenable to resection by medical therapy (rituximab, steroids), radiotherapy, or embolization. In this article, we report about the symptoms of this disease and about the diagnostics recommendation published in the International, evidence-based consensus diagnostic criteria for HHV-8-negative/ idiopathic multicentric Castleman disease and about the therapeutic recommendation published in International evidence-based consensus diagnostic and treatment guidelines for unicentric Castleman disease published in the year 2020.

Abstract
Hereditary hemorrhagic telangiectasia also known as Osler-Weber-Rendu syndrome, is an disorder that causes abnormal blood vessel formation with bleeding. Inhibition of angiogenesis amelioretes bleeding complication. Anti-angiogenic agents such as bevacizumab, aflibercept, thalidomid, lenadomid and other new anti-angiogenic thyrosinkinase inhibitors, as well as sirolimus and takrolimus have emerged as a promising systemic or local therapy in reducing bleeding complications but are not curative. Other pharmacological agents include iron supplementation, antifibrinolytics and hormonal treatment. This review concentrates on new anti-agioproliferative drugs with effect in HHT- discusses the new biology of HHT, management issues that face the practising hematologist, and considerations of future directions in HHT treatment.

Abstract
Transformation of IgM-MGUS into Waldenström´s macroglobulinemia in two of six patients treated for Schnitzler´s syndrome Schnitzler´s syndrome is a very rare, adult-onset, apparently acquired autoinflammatory disease. Chronic urticarial rash and symptoms of systemic inflammation including fever, arthralgia and bone pain with the presence of monoclonal immunoglobulin M (IgM), rarely IgG, are among hallmarks of the disease. We performed a retrospective study of 6 patients (5 men, 1 woman) diagnosed with Schnitzler´s syndrome fulfilling the Strasbourg criteria who had been treated at our centre in the University Hospital Brno from 2007 to 2021. Median age at diagnosis was 54 (45-67) years, median follow up was 8 (3-14) years. All 6 patients had IgM κ monoclonal gammopathy, increased CRP and/or erythrocyte sedimentation rate and arthralgia or bone pain, 4 patients suffered from fever, three had leucocytosis 10 × 109/L and lymphadenopathy was found in one patient. 18FDG-PET/CT scan with low-dose total body CT became a part of the initial baseline assessment in 5 patients with suspected Schnitzler´s syndrome, while Na18F-PET/CT was used in one patient to confirm the presence of osteosclerotic leasions as a criterion of the disease. All patients had osteosclerotic or hyperostotic bone lesions detected by low-dose CT examination, with increased 18FDG uptake in illiac and femoral bone marrow. The patient with Na18F-PET/CT scan revealed intensive abnormal tracer uptake with Na18F-PET/CT being more sensitive for detection of osteosclerotic lesions in Schnitzler´s syndrome than 18FDG-PET/CT. All patients were treated with daily subcutaneous anakinra without any adverse events, with excellent clinical results. We observed complete disappearance of urticaria and other symptoms persisting during years of anakinra administration. IgM-MGUS transformed into Waldenström´s macroglobulinemia in two of six patients, but only one patient developed symptoms requiring RBD (Rituximab, Bendamustin, and Dexamethasone) treatment, which induced almost complete remission of the disease. Successful RBD therapy enabled to prolong intervals of maintenance anakinra from 24 to 48 hours with almost complete control of urticarial rash and other symptoms. We suggest close monitoring of patients with Schnitzler´s syndrome to early capture potential transformation into Waldenström´s macroglobulinemia with succesful treatment of both conditions.

Abstract
Three adult patients with confirmed Erdheim-Chester disease (ECD) are followed at our department. Cladribine in monotherapy or in combination with cyclophosphamide were used for first line therapy. The median number of cycles of cladribine or cladribine and cyclophosphamide was 7 (range 6-8). In two cases complete response was achieved, in one case this therapy achieved no response. The duration of response is in one case 11 years, in second case the follow up is too short for evaluation of response duration. In case of no-response to cladribine and cyclophosphamide stabilisation of disease was achieved with anakinra. The tolerance was good without any toxicity grade II and higher. Cladribin and cyclophosphamide is one option for treatment of Erdheim-Chester disease.

Abstract
Despite the availability of new therapies that have led to improved outcomes for patients with multiple myeloma, most patients will eventually relapse. With triplet and even quadruplet combination therapies becoming standard in the first and second line, many patients will have few treatment options after second-line treatment. Melflufen (melphalan flufenamide) is a first-in-class peptide-drug conjugate (PDC) that targets aminopeptidases and rapidly releases alkylating agents into tumor cells. Once inside the tumor cells, melflufen is hydrolyzed by peptidases to release alkylator molecules, which become entrapped. Melflufen showed anti-myeloma activity in myeloma cells that were resistant to bortezomib and the alkylator melphalan. In early phase studies (O-12-M1 and HORIZON [OP-106]), melflufen plus dexamethasone has demonstrated encouraging clinical activity and a manageable safety profile in heavily pretreated patients with relapsed/refractory multiple myeloma, including those with triple-class refractory disease and extramedullary disease. The Phase III OCEAN study (OP-104) is further evaluating melflufen plus dexamethasone in patients with relapsed/refractory multiple myeloma. The safety profile of melflufen is characterized primarily by clinically manageable hematologic adverse events. Melflufen, with its novel mechanism of action, has the potential to provide clinically meaningful benefits to patients with relapsed/refractory multiple myeloma, including those with high unmet needs.

Abstract
Monoclonal gammopathy of undetermined significance (MGUS) is a known precursor of more serious cancers, such as multiple myeloma (MM), Waldenström macroglobulinemia (MW) and other lymphoproliferative disorders. Using 18F-FDG PET/CT, we aimed to evaluate its benefit in early detection of various accompanying disorders and illnesses in MGUS patients. We prospectively analyzed the diagnostic relevance of 18F-FDG PET/CT in 390 newly diagnosed MGUS patients. On 18F-FDG PET/CT scans, the presence of focal or diffuse areas of detectable increased tracer uptake was recorded in 37 (9.5%) MGUS patients. The most frequent pathology was lymphadenopathy (3.8%), followed by thyroid diseases (2.1%), rheumatic diseases (1.8%), and other solid malignancies (1.5%). These results have major implications for confirmed associations of MGUS with numerous malignant and non-malignant disorders. We believe that 18F-FDG PET/CT imaging in newly diagnosed MGUS patients may be useful in early detection of other serious pathologies, not only in predicting progression of MGUS to active MM, and should be strongly recommended if available.

Abstract
Smouldering multiple myeloma (SMM) presents without MM defining symptoms. We aimed to identify patients with SMM with an 80% risk of progression within 2 years using only serum parameters. In total, 527 patients with SMM were included and divided into a training group (287 patients from the Czech Myeloma Group [CMG]) and an independent validation group (240 patients from Heidelberg). The median follow-up was 2·4 and 2·5 years, respectively. Progression to MM occurred in 51·9% of the CMG and 38·8% of the Heidelberg patients, respectively. The median risk of progression was 11·0% (CMG) and 9·7% (Heidelberg) per year, during the 5 years after diagnosis. A serum involved/uninvolved free light-chain ratio of >30, immunoparesis, and serum monoclonal (M) protein of ≥2·3 g/dl emerged as powerful predictors of 2-year progression rate with a hazard ratio (HR) of 2·49 (95% confidence interval [CI] 1·49-4·17), HR of 2·01 (95% CI 1·36-2·96) and HR of 2·00 (95% CI 1·44-2·79) (P < 0·001) in univariate Cox regression analysis, respectively. Based on this, the CMG model identified patients with SMM with a 2-year risk of progression of 78·7% (95% CI 53·1-95·7; HR 6·8; P < 0·001, CMG) and 81·3% (95% CI 47·1-98·8; HR 38·63; P < 0·001, Heidelberg). Serum parameters in the CMG model allow identification of patients with SMM with an 80% risk of progression to symptomatic MM within 2 years.

Abstract
OBJECTIVE To predict the real-world (RW) cost-effectiveness of carfilzomib in combination with lenalidomide and dexamethasone (KRd) versus lenalidomide and dexamethasone (Rd) in relapsed multiple myeloma (MM) patients after one to three prior therapies. METHODS A partitioned survival model that included three health states (progression-free, progressed disease and death) was built. Progression-free survival (PFS), overall survival (OS) and time to discontinuation (TTD) data for the Rd arm were derived using the Registry of Monoclonal Gammopathies in the Czech Republic; the relative treatment effects of KRd versus Rd were estimated from the phase 3, randomised, ASPIRE trial, and were used to predict PFS, OS and TTD for KRd. The model was developed from the payer perspective and included drug costs, administration costs, monitoring costs, palliative care costs and adverse-event related costs collected from Czech sources. RESULTS The base case incremental cost effectiveness ratio for KRd compared with Rd was €73,156 per quality-adjusted life year (QALY) gained. Patients on KRd incurred costs of €117,534 over their lifetime compared with €53,165 for patients on Rd. The QALYs gained were 2.63 and 1.75 for patients on KRd and Rd, respectively. CONCLUSIONS Combining the strengths of randomised controlled trials and observational databases in cost-effectiveness models can generate policy-relevant results to allow well-informed decision-making. The current model showed that KRd is likely to be cost-effective versus Rd in the RW and, therefore, the reimbursement of KRd represents an efficient allocation of resources within the healthcare system.

Abstract
The histiocytoses are rare disorders characterized by the accumulation of cells thought to be derived from dendritic cells or macrophages. Their clinical behaviour ranges from mild to disseminated and, sometimes, life-threatening forms. The incidence of this diseases is much smaller, then the incidence of diseases derived from lymphocytic or myeloid lineage. Langerhans cell histiocytosis is most frequent disease from this group. The last version of WHO classification from 2017 and last version of classification published by Histiocyte Society is summarised in this paper.

Abstract
BACKGROUND Thalidomide-and bortezomib-containing regimens are widely used for transplant-ineligible newly diagnosed multiple myeloma patients. The aim of this study was to analyse the efficiency of thalidomide-or bortezomib-based regimens in long-term follow-up. MATERIALS AND METHODS From 2008 to 2012, 142 transplant-ineligible newly diagnosed multiple myeloma patients were analysed retrospectively. Bortezomib was administered at the standard dosing of 1.3mg/m2 weekly, and thalidomide was administered at a daily dose of 100mg. Both drugs were combined with cyclophosphamide and dexamethasone. A total of 95 patients were treated with thalidomide and 47 with bortezomib. A median four cycles of treatment were administered in both groups. RESULTS In the thalidomide group, the overall response rate was 60.6%, the median progression-free survival (PFS) was 10.3 months (95% CI 7.4-13.2) and the median overall survival (OS) was 35.1 months (95% CI 23.9-46.3). In the bortezomib group, the overall response rate was 51.1%, the median PFS was 11.9 months (95% CI 8.8-15) and the median OS was 25.4 months (95% CI 9.3-41.6). There was a statistically significant difference in OS (p = 0.027), favouring the cyclophosphamide/thalidomide/dexamethasone group, but the response rates and PFS intervals were not significantly different between both groups. The median follow-up in the thalidomide group was 35.1 months (95% CI 0.2-95.9) compared to 25.1 months (95% CI 0.4-60.6) in the bortezomib group (p = 0.004). The incidence of serious adverse events was comparable in both groups. CONCLUSION In conclusion, the results of bortezomib treatment are comparable to thalidomide treatment under conditions of short administration. According to other clinical trials, long-term bortezomib treatment provides an additional advantage for PFS and OS.

Abstract
Nowadays, bortezomib, a proteasome inhibitor, is widely used in treatment of newly diagnosed or relapsed multiple myeloma. The aim of this study was to analyze efficiency of bortezomib retreatment in patients with relapsed or refractory multiple myeloma. From 2004 to 2016, 283 patients were retrospectively evaluated at all hematological centers in the Czech Republic. Bortezomib was administered at the standard dosing and in combined therapy with corticosteroids, chemotherapy or thalidomide. Before bortezomib retreatment, 61% of patients received previous lenalidomide treatment, 40.6% autologous transplantation, and median number of prior lines of therapy was three. In total, 21% of patients were refractory to the first bortezomib treatment. In bortezomib retreatment, overall response rate was 34.5%, median progression-free survival was 7.8 months (95% CI: 6.7-8.9), median duration of response was 10.5 months (95% CI: 8.0-13.0) and median overall survival was 20.3 months (95% CI: 17.9-22.7). Grade 3-4 adverse events included thrombocytopenia, neutropenia, anemia and infection. Neuropathy grade 2 or higher occurred in 19.4% of patients. We conclude that bortezomib retreatment is an effective and safe therapeutic alternative for relapsed or refractory multiple myeloma patients.

Abstract
Unlike bone marrow biopsies, liquid biopsies represent a gentler, more accessible, less painful, repeatable and more comprehensive approach to get biologically relevant information about the entire tumor but also about treatment response and level of minimal residual disease. This is all possible since peripheral blood contains not only circulating tumor cells but also many circulating molecules of nucleic acids (microRNA, cell-free DNA, long non-coding RNA etc.). Multiple myeloma is a genetically heterogeneous disease characterized by multifocal tumor deposits in the bone marrow but also focal lesions elsewhere. Single-site biopsy of the bone marrow creates a sampling bias that provides a limited molecular profile as the biopsy cannot capture all subclones. Moreover, during disease progression and treatment, molecular profile is changed and subclones of multiple myeloma cells resistant to treatment are formed. Likewise, various clones found in extramedullary sites that are not present in the bone marrow respond differently to treatment directly influencing survival of patients. Thus, liquid biopsies seem to be a relevant and necessary next step for diseases such as multiple myeloma.Key words: multiple myeloma - minimal residual disease - prognosis - liquid biopsies - cell-free DNA - non-coding RNA.

Abstract
BACKGROUND Progress in treatment of multiple myeloma extensively increased patient remission rates, so minimal residual disease (MRD) detection becomes essential to assess the effectivity of treatment and depth of complete response. Nowadays, multiparametric flow cytometry (MFC) is the most used method for monitoring of MRD presence in the bone marrow of multiple myeloma patients; however, detection on molecular level can be used as well. It is evident that choice of protocol used for MFC-MRD assessment can significantly affect required results; nevertheless, standardized and highly sensitive approach of "next generation flow" is already available. Although benefit of MRD assessment as an independent predictor of progression-free survival and overall survival is known, very recent research showed that MRD-negative status surpasses the prognostic value of complete response achievement for progression-free survival and overall survival. AIM This review is focused on use MFC in MRD assessment in multiple myeloma. The technical aspects and clinical benefits of this approach are mentioned as well. CONCLUSION The information about MRD level detected by highly sensitive and reproducible MFC can be potentially used as a biomarker to evaluate the efficacy of different treatment strategies, help on treatment decisions and act as a surrogate for overall survival in multiple myeloma patients.Key words: multiple myeloma - minimal residual disease - flow cytometry - plasma cells.

Abstract
Immunoglobulin light chain amyloidosis (AL amyloidosis - ALA) is a monoclonal gammopathy characterized by presence of aberrant plasma cells producing amyloidogenic immunoglobulin light chains. This leads to formation of amyloid fibrils in various organs and tissues, mainly in heart and kidney, and causes their dysfunction. As amyloid depositing in target organs is irreversible, there is a big effort to identify biomarker that could help to distinguish ALA from other monoclonal gammopathies in the early stages of disease, when amyloid deposits are not fatal yet. High throughput technologies bring new opportunities to modern cancer research as they enable to study disease within its complexity. Sophisticated methods such as next generation sequencing, gene expression profiling and circulating microRNA profiling are new approaches to study aberrant plasma cells from patients with light chain amyloidosis and related diseases. While generally known mutation in multiple myeloma patients (KRAS, NRAS, MYC, TP53) were not found in ALA, number of mutated genes is comparable. Transcriptome of ALA patients proves to be more similar to monoclonal gammopathy of undetermined significance patients, moreover level of circulating microRNA, that are known to correlate with heart damage, is increased in ALA patients, where heart damage in ALA typical symptom.Key words: amyloidosis - plasma cell - genome - transcriptome - microRNA.
