Carfilzomib combined with lenalidomide and dexamethasone (KRd) as salvage therapy for multiple myeloma patients: italian, multicenter, retrospective clinical experience with 600 cases outside of controlled clinical trials.

In combination with lenalidomide and dexamethasone (KRd), Carfilzomib has been approved for the treatment of relapsed and refractory multiple myeloma (RRMM) on ASPIRE trial. Efficacy and safety of the triplet are still the object of investigation by many groups to confirm ASPIRE results in the setting of RRMM treated in real-life who don't meet trial restrictive inclusion criteria. Therefore, we report a retrospective multicenter analysis of 600 RRMM patients treated with KRd between December 2015 and December 2018. The median age was 64 years (range 33-85), and the median number of previous therapies was two (range 1-11). After a median of 11 KRd cycles, the overall response rate was 79.9%. The median progression-free survival (PFS) was 22 months, and the 2-year probability of PFS was 47.6%. Creatinine clearance<30 ml/min, >1 line of previous therapy, and high-risk FISH were all associated with a poor prognosis in multivariate analysis. The median overall survival (OS) was 34.8 months; the 2-year probability of OS was 63.5%. At multivariate analysis, creatinine clearance<30 ml/min, >1 line of previous therapy, and high-risk FISH were significantly associated with poor prognosis. After a median follow-up of 16 months (range 1-50), 259 withdrew from therapy. The main discontinuation reason was progressive disease (81.8%). Seventy-four patients (12.3%) discontinued therapy for toxicity. The most frequent side effects were hematological (anemia 49.3%, neutropenia 42.7%, thrombocytopenia 42.5%) and cardiovascular (hypertension 14.5%, heart failure 2.5%, arrhythmias 3.6%). Our study confirms the safety and efficacy of KRd in the real-life setting of RRMM patients and encourages its use in clinical practice.

Adjusted comparison between elotuzumab and carfilzomib in combination with lenalidomide and dexamethasone as salvage therapy for multiple myeloma patients.

The lack of a randomized trial comparing carfilzomib (K) versus elotuzumab (Elo) associated with lenalidomide and dexamethasone (Rd) prompted us to assess the relative usefulness of one triplet over the other. Five independent retrospective cohorts of 883 relapsed/refractory multiple myeloma (RRMM) patients, including 300 EloRd and 583 KRd cases, outside clinical trials, entered this non-randomized comparison. KRd cohort accounted for a higher incidence of younger patients, cases with ≥3 lines of therapy, already exposed to lenalidomide, International Staging System (ISS) stage III, and abnormal lactic dehydrogenase (LDH) level compared with EloRd cohort. Moreover, cytogenetic risk categories, detected in roughly one-third of cases, were equally distributed between the two therapy arms. The probability of CR+VGPR response was significantly higher in KRd (n = 314, 53.9%) than in EloRd patients (n = 111, 37.0%). Likewise, the cumulative incidence function of CR+VGPR, taking into account the competitive risk of death, was significantly higher in KRd arm patients than those in the EloRd arm (p = .003). Moreover, KRd treatment significantly reduced the progression or death risk by 46% in an adjusted multivariate analysis (HR: 0.54, 95% CI 0.42-0.69, p < .0001). Finally, in an adjusted illness-progression/death model, the effect of KRd versus EloRd was of higher magnitude among those who achieved CR+VGPR (-39% hazard ratio reduction, p = .02) than among those who achieved < VGPR (-29% hazard ratio reduction, p = .007). With limitations characteristic to any retrospective analysis, this current clinical practice study's overall results demonstrated potential benefits of KRd therapy compared with EloRd. This observation may help the daily clinical practice.

Italian guidelines on management of persons with multimorbidity and polypharmacy.

Multimorbidity and polypharmacy are emerging health priorities and the care of persons with these conditions is complex and challenging. The aim of the present guidelines is to develop recommendations for the clinical management of persons with multimorbidity and/or polypharmacy and to provide evidence-based guidance to improve their quality of care. The recommendations have been produced in keeping with the Grading of Recommendations Assessment, Development and Evaluation (GRADE). Overall, 14 recommendations were issued, focusing on 4 thematic areas: (1.) General Principles; (2.) target population for an individualized approach to care; (3.) individualized care of patients with multimorbidity and/or polypharmacy; (4.) models of care. These recommendations support the provision of individualized care to persons with multimorbidity and/or polypharmacy as well as the prioritization of care through the identification of persons at increased risk of negative health outcomes. Given the limited available evidence, recommendations could not be issued for all the questions defined and, therefore, some aspects related to the complex care of patients with multimorbidity and/or polypharmacy could not be covered in these guidelines. This points to the need for more research in this field and evidence to improve the care of this population.

Visual and volumetric parameters by 18F-FDG-PET/CT: a head to head comparison for the prediction of outcome in patients with multiple myeloma.

In multiple myeloma (MM) patients, 18F-FDG-PET/CT allows either the detection of disease spread by using visual parameters based on the Italian Myeloma criteria for PET Use (IMPeTUs) or the direct measurement of metabolic tumor burden by volume-based parameters such as metabolic tumor volume (MTV). The purpose is to evaluate the contribution of visual and volumetric parameters in the prediction of progression-free survival (PFS) and overall survival (OS) in MM patients. Forty-seven patients in stage IIIA who had undergone whole-body 18F-FDG-PET/CT were retrospectively evaluated. In each patient, visual parameters were determined and compared with volumetric parameters for PFS and OS prediction after a mean follow-up period of 53 months. Among the visual and volumetric parameters tested, a statistically significant difference was found between maximum standardized uptake value, MTV, total lesion glycolysis, and number of lytic lesions of patients with (n = 26) or without (n = 21) progression (p = 0.0400, p = 0.0065, p = 0.015, and p = 0.0220, respectively) and of dead (n = 24) vs survivors (n = 23) (p = 0.0171, p = 0.0037, p = 0.0060, and p = 0.0270, respectively). At univariate and multivariate analysis, MTV and hemoglobin were predictive of both PFS (p = 0.008) and OS (p = 0.0026). The best MTV discriminative value assessed by receiver operating characteristic curve analysis for predicting both PFS and OS was 39.4 ml. By Kaplan-Meier analysis and log-rank test, PFS and OS were significantly better in patients with MTV ≤ 39.4 ml (p = 0.0004 and p = 0.0001, respectively) as compared with those having an MTV higher than the cutoff. The volume-based parameter MTV determined by 18F-FDG-PET/CT may be used in the prediction of PFS and OS in myeloma patients.

An 1H NMR study of the cytarabine degradation in clinical conditions to avoid drug waste, decrease therapy costs and improve patient compliance in acute leukemia.

Cytarabine, the 4-amino-1-(ß-D-arabinofuranosyl)-2(1H)-pyrimidinone, (ARA-C) is an antimetabolite cytidine analogue used worldwide as key drug in the management of leukaemia. As specified in the manufacturers' instructions, once the components-sterile water and cytarabine powder-are unpackaged and mixed, the solution begins to degrade after 6 hours at room temperature and 12 hours at 4°C. To evaluate how to avoid wasting the drug in short-term, low-dose treatment regimens, the reconstituted samples, stored at 25°C and 4°C, were analyzed every day of the test week by reversed-phase HPLC and high-field NMR spectroscopy. All the samples remained unchanged for the entire week, which corresponds to the time required to administer the entire commercial drug package during low-dose therapeutic regimens. The drug solution was stored in a glass container at 4°C in an ordinary freezer and drawn with sterile plastic syringes; during this period, no bacterial or fungal contamination was observed. Our findings show that an cytarabine solution prepared and stored in the original vials retains its efficacy and safety and can, therefore, be divided into small doses to be administered over more days, thus avoiding unnecessary expensive and harmful waste of the drug preparation. Moreover, patients who require daily administration of the drug could undergo the infusion at home without need to go to hospital. The stability of the aliquots would help decrease hospitalization costs.

Is re-challenge still an option as salvage therapy in multiple myeloma? The case of REal-life BOrtezomib re-Use as secoND treatment for relapsed patients exposed frontline to bortezomib-based therapies (the REBOUND Study).

Therapeutic re-challenge is currently a debated issue in the field of multiple myeloma (MM), given the recent availability of several new drugs and combinations. However, very few specific evidences are available about bortezomib re-use at first relapse. This multicenter, observational, retrospective study enrolled 134 MM patients with significant response after bortezomib-based frontline regimens and who had received a first salvage treatment containing bortezomib at relapse. The overall response rate was 71%, including 40% partial responses, 24% very good partial responses, and 7% complete responses. Re-treatment was well-tolerated, with no significant new or unexpected toxicities observed. The median duration of second progression-free survival (PFS) was 15 months, while median PFS2 was 55 months. With a median follow-up of 56 months, overall survival was 94 months for the entire series, without significant differences between patients undergoing or not undergoing transplant procedures. This real-life survey indicates that re-treatment including bortezomib as a first salvage therapy could be still considered in MM patients achieving durable response after initial exposure to bortezomib.

Lenalidomide at the dose of 25 mg every other day in patients affected by multiple myeloma and renal failure: a real-life experience.

Renal impairment (RI) is a relevant complication of patients affected by multiple myeloma (MM); it can be present in up to 30-35% of newly diagnosed MM and is linked to a poor outcome. However, early recognition and early treatment with novel agents can overcome the negative impact of RI and even reverse kidney damage in most cases. Lenalidomide, available as an oral compound, is an immunomodulatory drug with both antiproliferative and immunomodulatory activity that is largely used in the management of MM. Dose reduction is mandatory in RI; however, there is no theoretical assumption against the possibility that protracting the time of full standard doses can be equally effective and tolerated by patients requiring reduced doses. In this report, we describe our retrospective experience, in 18 patients, with the administration of lenalidomide 25 mg every other day for patients with MM and RI. The overall response ratio was 66.5%. More than half (61.1%) of the patients had a renal response. The median progression-free survival was 8 months (range: 3-18 months). No serious adverse event occurred during treatment, and it was never necessary to disrupt or delay treatment for toxicity. These preliminary observations point to a significant therapeutic effect of lenalidomide, at the dose of 25 mg every other day for 21 days, with logistic and economic advantages. However, these results should be validated by controlled studies involving larger numbers of patients.

Safety and comfort of domestic bortezomib injection in real-life experience.

Despite novel agents, multiple myeloma is still an incurable disease, especially for elderly and frail patients, who are difficult to manage for concomitant comorbidities as the therapeutic options are limited and the response to chemotherapy is often short. We report our evaluations upon safety and efficacy of domestic subcutaneous bortezomib in elderly and frail patients candidate to bortezomib-melphalan-prednisone (VMP) regimen. We confirmed that overall incidence of adverse events, including peripheral neuropathy, was low, and in no case required admission to emergency service, contributing to reduce the rate of therapy discontinuation. These results confirm the effectiveness and safety of subcutaneous bortezomib, in a real-life-experience, and define a new possibility of safe auto-administration in a comfortable domestic setting. We suggest that domestic treatment can significantly improve the quality of life of the patients, avoiding unnecessary transfer to the hospital without reducing treatment efficacy.

Autologous transplantation and maintenance therapy in multiple myeloma.

BACKGROUND: This open-label, randomized, phase 3 study compared melphalan at a dose of 200 mg per square meter of body-surface area plus autologous stem-cell transplantation with melphalan-prednisone-lenalidomide (MPR) and compared lenalidomide maintenance therapy with no maintenance therapy in patients with newly diagnosed multiple myeloma. METHODS: We randomly assigned 273 patients 65 years of age or younger to high-dose melphalan plus stem-cell transplantation or MPR consolidation therapy after induction, and 251 patients to lenalidomide maintenance therapy or no maintenance therapy. The primary end point was progression-free survival. RESULTS: The median follow-up period was 51.2 months. Both progression-free and overall survival were significantly longer with high-dose melphalan plus stem-cell transplantation than with MPR (median progression-free survival, 43.0 months vs. 22.4 months; hazard ratio for progression or death, 0.44; 95% confidence interval [CI], 0.32 to 0.61; P<0.001; and 4-year overall survival, 81.6% vs. 65.3%; hazard ratio for death, 0.55; 95% CI, 0.32 to 0.93; P=0.02). Median progression-free survival was significantly longer with lenalidomide maintenance than with no maintenance (41.9 months vs. 21.6 months; hazard ratio for progression or death, 0.47; 95% CI, 0.33 to 0.65; P<0.001), but 3-year overall survival was not significantly prolonged (88.0% vs. 79.2%; hazard ratio for death, 0.64; 95% CI, 0.36 to 1.15; P=0.14). Grade 3 or 4 neutropenia was significantly more frequent with high-dose melphalan than with MPR (94.3% vs. 51.5%), as were gastrointestinal adverse events (18.4% vs. 0%) and infections (16.3% vs. 0.8%); neutropenia and dermatologic toxic effects were more frequent with lenalidomide maintenance than with no maintenance (23.3% vs. 0% and 4.3% vs. 0%, respectively). CONCLUSIONS: Consolidation therapy with high-dose melphalan plus stem-cell transplantation, as compared with MPR, significantly prolonged progression-free and overall survival among patients with multiple myeloma who were 65 years of age or younger. Lenalidomide maintenance, as compared with no maintenance, significantly prolonged progression-free survival. (Funded by Celgene; ClinicalTrials.gov number, NCT00551928.).

Pegfilgrastim in primary prophylaxis of febrile neutropenia following frontline bendamustine plus rituximab treatment in patients with indolent non-Hodgkin lymphoma: a single center, real-life experience.

BACKGROUND: In this prospective study, the impact of granulocyte colony-stimulating factors (G-2 CSF) administered during induction treatment with bendamustine plus rituximab for indolent non- Hodgkin Llymphoma (NHL) was evaluated by comparing patients who received secondary prophylaxis with filgrastim (control group) versus. patients who received pegfilgrastim as primary prophylaxis (peg-group). The primary endpoint was the incidence rate of febrile neutropenia (FN)- related chemotherapy disruptions (regarding dose-dense and/or dose-intensity of schedule). The Ssecondary endpoint included days of hospitalization due to FN, and G-CSF-related side effects (grade ≥3 WHO toxicity criteria) in each group. METHODS: One hundred twenty-two: 122 consecutive patients, with untreated indolent NHL, were referred to our outpatient unit for remission induction immuno-chemotherapy with bendamustine-rituximab. During the first period, 61 patients received secondary prophylaxis with filgrastim, given "on demand" if ANC was <1000/mm3. During the second period, 61 patients received primary prophylaxis with pegfilgrastim in a single administration. RESULTS: Pegfilgrastim was significantly associated with fewer incidence rate of FN-related chemotherapy disruptions (11.4% in the control group vs. 1.6% in the peg-group, p = 0.04) and fewer days of hospitalization due to FN (median number 18 days in the control group vs. 6 in the peg-group, p = 0.04). In terms of G-CSF-related extra-hematological grade III side effects, no significant difference has been found in the two groups (9.8% in the control group vs. 11.5% in the peg-group, p = 0.77). Only one patient stopped the treatment in the peg-group due to intolerance. CONCLUSIONS: In patients with indolent NHL, in front-line treatment with bendamustine plus rituximab, primary prophylaxis with pegfilgrastim seems to reduce the incidence of chemotherapy disruptions due to FN, and the days of hospitalization. Moreover, it is well- tolerated and may increase the opportunity to maintain the planned schedule of treatment. These results make pegfilgrastim an advantageous option in most cases both in terms of cost-effectiveness and quality of life. These preliminary observations need to be validated by controlled clinical trials.

Longitudinal strain of left ventricular basal segments and E/e' ratio differentiate primary cardiac amyloidosis at presentation from hypertensive hypertrophy: an automated function imaging study.

BACKGROUND: Longitudinal strain is an early marker of left ventricular (LV) dysfunction in several cardiac diseases. Our aim was to differentiate cardiac amyloidosis (CA) at diagnosis from hypertensive LV hypertrophy (LVH) by analysis of longitudinal myocardial deformation. METHODS: Thirty healthy controls (C), 30 newly diagnosed, never treated hypertensives with LVH (H-LVH), and 33 patients with CA at diagnosis underwent echo Doppler including speckle tracking-based automated function imaging (AFI). Averaged peak systolic global longitudinal strain (GLS, 18 segments) and basal, middle, and apical longitudinal strain (BLS, MLS, and ALS, respectively, six segments each) were calculated. RESULTS: Left ventricular mass index, relative wall thickness, and ejection fraction did not differ between H-LVH and CA. E/e' ratio was higher in CA than in H-LVH (P<.001) and C (P<.0001). GLS was lower in CA than in C (P<.0001), without difference with H-LVH. ALS did not differ among the three groups, MLS was significantly lower in both CA and H-LVH than in C but BLS was lower in CA compared to both H-LVH and C (both P<.0001). In the pooled population, E/e' was independently associated with BLS (ß=-0.54, P<.0001). At receiver operating curve analysis, CA was predicted by BLS≤-11.3% (sensitivity=63.3%, specificity=100%) and E/e'≥12.3 (sensitivity=69.7%, specificity=83.3%). The best AUC (=0.819) was obtained by the combination E/e'+BLS. CONCLUSIONS: Our findings highlight a real difference of E/e' ratio and longitudinal strain of LV basal segments between hypertensive LVH and CA, which could be used to differentiate the two diseases.

Chemotherapy plus lenalidomide versus autologous transplantation, followed by lenalidomide plus prednisone versus lenalidomide maintenance, in patients with multiple myeloma: a randomised, multicentre, phase 3 trial.

BACKGROUND: High-dose melphalan plus autologous stem-cell transplantation (ASCT) is the standard approach in transplant-eligible patients with newly diagnosed myeloma. Our aims were to compare consolidation with high-dose melphalan plus ASCT versus chemotherapy (cyclophosphamide and dexamethasone) plus lenalidomide, and maintenance with lenalidomide plus prednisone versus lenalidomide alone. METHODS: We did an open-label, randomised, multicentre, phase 3 study at 59 centres in Australia, Czech Republic, and Italy. We enrolled transplant-eligible patients with newly diagnosed myeloma aged 65 years or younger. Patients received a common induction with four 28-day cycles of lenalidomide (25 mg, days 1-21) and dexamethasone (40 mg, days 1, 8, 15, and 22) and subsequent chemotherapy with cyclophosphamide (3 g/m(2)) followed by granulocyte colony-stimulating factor for stem-cell mobilisation and collection. Using a 2 × 2 partial factorial design, we randomised patients to consolidation with either chemotherapy plus lenalidomide (six cycles of cyclophosphamide [300 mg/m(2), days 1, 8, and 15], dexamethasone [40 mg, days 1, 8, 15, and 22], and lenalidomide [25 mg, days 1-21]) or two courses of high-dose melphalan (200 mg/m(2)) and ASCT. We also randomised patients to maintenance with lenalidomide (10 mg, days 1-21) plus prednisone (50 mg, every other day) or lenalidomide alone. A simple randomisation sequence was used to assign patients at enrolment into one of the four groups (1:1:1:1 ratio), but the treatment allocation was disclosed only when the patient reached the end of the induction and confirmed their eligibility for consolidation. Both the patient and the treating clinician did not know the consolidation and maintenance arm until that time. The primary endpoint was progression-free survival assessed by intention-to-treat. The trial is ongoing and some patients are still receiving maintenance. This study is registered at ClinicalTrials.gov, number NCT01091831. FINDINGS: 389 patients were enrolled between July 6, 2009, and May 6, 2011, with 256 eligible for consolidation (127 high-dose melphalan and ASCT and 129 chemotherapy plus lenalidomide) and 223 eligible for maintenance (117 lenalidomide plus prednisone and 106 lenalidomide alone). Median follow-up was 52·0 months (IQR 30·4-57·6). Progression-free survival during consolidation was significantly shorter with chemotherapy plus lenalidomide compared with high-dose melphalan and ASCT (median 28·6 months [95% CI 20·6-36·7] vs 43·3 months [33·2-52·2]; hazard ratio [HR] for the first 24 months 2·51, 95% CI 1·60-3·94; p<0·0001). Progression-free survival did not differ between maintenance treatments (median 37·5 months [95% CI 27·8-not evaluable] with lenalidomide plus prednisone vs 28·5 months [22·5-46·5] with lenalidomide alone; HR 0·84, 95% CI 0·59-1·20; p=0·34). Fewer grade 3 or 4 adverse events were recorded with chemotherapy plus lenalidomide than with high-dose melphalan and ASCT; the most frequent were haematological (34 [26%] of 129 patients vs 107 [84%] of 127 patients), gastrointestinal (six [5%] vs 25 [20%]), and infection (seven [5%] vs 24 [19%]). Haematological serious adverse events were reported in two (2%) patients assigned chemotherapy plus lenalidomide and no patients allocated high-dose melphalan and ASCT. Non-haematological serious adverse events were reported in 13 (10%) patients assigned chemotherapy plus lenalidomide and nine (7%) allocated high-dose melphalan and ASCT. During maintenance, adverse events did not differ between groups. The most frequent grade 3 or 4 adverse events were neutropenia (nine [8%] of 117 patients assigned lenalidomide plus prednisone vs 14 [13%] of 106 allocated lenalidomide alone), infection (eight [8%] vs five [5%]), and systemic toxicities (seven [6%] vs two [2%]). Non-haematological serious adverse events were reported in 13 (11%) patients assigned lenalidomide plus prednisone versus ten (9%) allocated lenalidomide alone. Four patients died because of adverse events, three from infections (two during induction and one during consolidation) and one because of cardiac toxic effects. INTERPRETATION: Consolidation with high-dose melphalan and ASCT remains the preferred option in transplant-eligible patients with multiple myeloma, despite a better toxicity profile with chemotherapy plus lenalidomide. FUNDING: Celgene.

MET dysregulation is a hallmark of aggressive disease in multiple myeloma patients.

Abnormal activation of MET/HGF (Hepatocyte Growth Factor) pathway has been described in several tumours and increased HGF plasmatic levels have been detected in patients with aggressive multiple myeloma (MM). MET and HGF mRNA expression was investigated in 105 samples of purified plasma cells derived from newly diagnosed MM patients treated with bortezomib-based induction therapy. Gene expression was compared with response to therapy and clinical outcome. MET gene copy number was also evaluated. MET mRNA expression was higher in CD138(+) than in CD138(-) cells (median 76·90 vs. 11·24; P = 0·0009). Low MET mRNA expression characterized patients with better response (complete response or very good partial response) compared to other patients (median 56·10 vs. 134·83; P = 0·0006). After a median follow-up of 50 months, patients with high MET mRNA expression displayed a worse progression-free survival (PFS; P = 0·0029) and overall survival (OS; P = 0·0023) compared to those with low MET mRNA levels. Patients with both high MET mRNA expression and high ß2-microglobulin level (>5·5 mg/l) had further worse median PFS (P < 0·0001) and OS (P < 0·0001). Patients carrying 4 MET gene copies (8 out of 82, 9·8%) also had a short PFS. High MET mRNA expression identifies patients with dismal PFS and OS and the combination with high ß2-microglobulin further characterizes patients with worse outcome.

Aspirin or enoxaparin thromboprophylaxis for patients with newly diagnosed multiple myeloma treated with lenalidomide.

Lenalidomide plus dexamethasone is effective in the treatment of multiple myeloma (MM) but is associated with an increased risk of venous thromboembolism (VTE). This prospective, open-label, randomized substudy of a phase 3 trial compared the efficacy and safety of thromboprophylaxis with low-dose aspirin (ASA) or low-molecular-weight heparin (LMWH) in patients with newly diagnosed MM, treated with lenalidomide and low-dose dexamethasone induction and melphalan-prednisone-lenalidomide consolidation. Overall, 342 patients who did not have clinical indications or contraindications to antiplatelet or anticoagulant therapy were randomly assigned to receive ASA 100 mg/d (n = 176) or LMWH enoxaparin 40 mg/d (n = 166). The incidence of VTE was 2.27% in the ASA group and 1.20% in the LMWH group. Compared with LMWH, the absolute difference in the proportion of VTE was 1.07% (95% confidence interval, -1.69-3.83; P = .452) in the ASA group. Pulmonary embolism was observed in 1.70% of patients in the ASA group and none in the LMWH group. No arterial thrombosis, acute cardiovascular events, or sudden deaths were reported. No major hemorrhagic complications were reported. In previously untreated patients with MM receiving lenalidomide with a low thromboembolic risk, ASA could be an effective and less-expensive alternative to LMWH thromboprophylaxis.

Bortezomib, melphalan, prednisone (VMP) versus melphalan, prednisone, thalidomide (MPT) in elderly newly diagnosed multiple myeloma patients: A retrospective case-matched study.

Novel agents in combination with melphalan and prednisone (MP) significantly improved progression-free survival (PFS) and overall survival (OS) in multiple myeloma (MM). Randomized trials comparing MP plus bortezomib (VMP) versus MP plus thalidomide (MPT) are lacking. Nine hundred and fifty-six elderly (>65 years) newly diagnosed MM patients from six European randomized trials were retrospectively analyzed and matched for age, albumin, and beta2-microglobulin at diagnosis, 296 patients were selected from the VMP groups, and 294 from MPT. Complete response rate was 21% in the VMP patients and 13% in the MPT patients (P = 0.007). After a median follow-up of 34 months (range, 1-92), VMP significantly prolonged both PFS (median 32.5 vs. 22.9 months, HR 0.65; 95% CI 0.52-0.82; P < 0.001) and OS (median 79.7 vs. 45.1 months, HR 0.44; 95% CI 0.32-0.59; P < 0.001) in comparison with MPT. The benefit in terms of OS of the VMP group was quite similar among patients with different risk factors defined by sex, ISS, ECOG performance status, or serum creatinine but not among patients ≥ 75 years. Multivariate analysis confirmed that VMP was an independent predictor of longer PFS and OS. In a control-case matched analysis, PFS and OS were prolonged in patients who received VMP in comparison with those treated with MPT.

Nodular goiter with amyloid deposition in an elderly patient: fine-needle cytology diagnosis and review of the literature.

BACKGROUND: Amyloidosis is a systemic disease characterized by the extracellular deposition of amyloid fibrils in different organs and tissues. The thyroid gland may be affected by diffuse or nodular amyloid deposits, along with multiple myeloma (MM) (Amyloid Light-Chain Amyloidosis, AL amyloidosis) or chronic inflammatory diseases (Amyloid A Amyloidosis, AA amyloidosis), but thyroid gland involvement rarely appears as the first clinical manifestation in both conditions. The present study reports a case of primary thyroidal nodular amyloid goiter diagnosed by fine-needle cytology (FNC) in an elderly patient. CASE REPORT: A 66-year-old female patient presented with dysphagia and hoarseness; the patient suffered from rheumatoid arthritis but did not have kidney failure or altered thyroid function. Ultrasound examination (US) showed a 30 mm irregular, hypoechoic area in the left thyroid lobe. FNC showed abundant, dense and amorphous material similar to the one stained in purple at Diff-Quik stain and pinkish at the Papanicolaou. Spindle cells with thin, bland and bent nuclei were scattered in this material; few thyroid follicular cells were also present. An alcohol-fixed smear was stained with Congo red: the amyloid material appeared cherry red and it also showed apple-green birefringence when observed with a polarizing microscope. A differential diagnosis between different thyroid pathologies was considered and the cytological diagnosis of nodular amyloid goiter was pointed out. The patient underwent thyroid lobectomy and the subsequent histological examination confirmed the cytological diagnosis. CONCLUSIONS: FNC is a safe and effective procedure for the diagnosis of thyroid amyloidosis. Congo red-stained smears can be used to demonstrate the presence of amyloid material, showing the typical green birefringence under polarized light. An early and accurate cytological diagnosis may suggest an hematological screening and the appropriate treatment for the thyroid nodule.

Efficacy and safety of belantamab-mafodotin in triple-refractory multiple myeloma patients: A multicentric real-life experience.

Belantamab-mafodotin is an innovative and selective treatment for multi-refractory/relapsed multiple myeloma (MM) patients; however, available real-life experiences on efficacy and safety are limited. In this real-world multicentric retrospective study, we enrolled 28 MM patients treated in four Hematology units of Campania region, Italy, who received a median of six treatment lines prior to belantamab-mafodotin. The overall response rate (ORR) was 40% (complete remission, CR, 11%; very good partial remission, VGPR, 11%; and partial remission, PR, 18%), with a median progression-free survival (PFS) and overall survival (OS) of 3 and 8 months, respectively. One of the most frequent drug-related adverse events was keratopathy observed in nine (32%) patients, leading to therapy discontinuation in only three (11%) of them. Moreover, 22 out of 28 total patients who were treated with at least two administrations achieved an ORR of 50% (CR, 14%; VGPR, 14%; and PR, 22%) with a median PFS and OS of 5 and 11 months, respectively. In conclusion, our multicentric study confirmed efficacy and safety of belantamab-mafodotin in triple-refractory MM patients even in the real-life setting.

Survival Risk Scores for Real-Life Relapsed/Refractory Multiple Myeloma Patients Receiving Elotuzumab or Carfilzomib In Combination With Lenalidomide and Dexamethasone as Salvage Therapy: Analysis of 919 Cases Outside Clinical Trials.

The present study aimed to develop two survival risk scores (RS) for overall survival (OS, SRS KRd/EloRd ) and progression-free survival (PFS, PRS KRd/EloRd ) in 919 relapsed/refractory multiple myeloma (RRMM) patients who received carfilzomib, lenalidomide, and dexamethasone (KRd)/elotuzumab, lenalidomide, and dexamethasone (EloRd). The median OS was 35.4 months, with no significant difference between the KRd arm versus the EloRd arm. In the multivariate analysis, advanced ISS (HR = 1.31; P = 0.025), interval diagnosis-therapy (HR = 1.46; P = 0.001), number of previous lines of therapies (HR = 1.96; P < 0.0001), older age (HR = 1.72; P < 0.0001), and prior lenalidomide exposure (HR = 1.30; P = 0.026) remained independently associated with death. The median PFS was 20.3 months, with no difference between the two strategies. The multivariate model identified a significant progression/death risk increase for ISS III (HR = 1.37; P = 0.002), >3 previous lines of therapies (HR = 1.67; P < 0.0001), older age (HR = 1.64; P < 0.0001), and prior lenalidomide exposure (HR = 1.35; P = 0.003). Three risk SRS KRd/EloRd categories were generated: low-risk (134 cases, 16.5%), intermediate-risk (467 cases, 57.3%), and high-risk categories (213 cases, 26.2%). The 1- and 2-year OS probability rates were 92.3% and 83.8% for the low-risk (HR = 1, reference category), 81.1% and 60.6% (HR = 2.73; P < 0.0001) for the intermediate-risk, and 65.5% and 42.5% (HR = 4.91; P < 0.0001) for the high-risk groups, respectively. Notably, unlike the low-risk group, which did not cross the median timeline, the OS median values were 36.6 and 18.6 months for the intermediate- and high-risk cases, respectively. Similarly, three PRS KRd/EloRd risk categories were engendered. Based on such grouping, 338 (41.5%) cases were allocated in the low-, 248 (30.5%) in the intermediate-, and 228 (28.0%) in the high-risk groups. The 1- and 2-year PFS probability rates were 71.4% and 54.5% for the low-risk (HR = 1, reference category), 68.9% and 43.7% (HR = 1.95; P < 0.0001) for the intermediate-risk, and 48.0% and 27.1% (HR = 3.73; P < 0.0001) for the high-risk groups, respectively. The PFS median values were 29.0, 21.0, and 11.7 months for the low-, intermediate-, and high-risk cases. This analysis showed 2.7- and 4.9-fold increased risk of death for the intermediate- and high-risk cases treated with KRd/EloRd as salvage therapy. The combined progression/death risks of the two categories were increased 1.3- and 2.2-fold compared to the low-risk group. In conclusion, SRS KRd/EloRd and PRS KRd/EloRd may represent accessible and globally applicable models in daily clinical practice and ultimately represent a prognostic tool for RRMM patients who received KRd or EloRd.
