RESUMO

Ixazomib, the first oral proteasome inhibitor (PI), has been approved for the treatment of relapsed refractory multiple myeloma (RRMM) in combination with lenalidomide and dexamethasone, based on the TOURMALINE-MM1 phase 3 trial, which demonstrated the efficacy and safety of this all-oral triplet, compared with lenalidomide-dexamethasone. However, clinical trial outcomes do not always translate into real-world outcomes. The aim of this study was to assess the outcomes of ixazomib-based combination for treatment of patients with RRMM in a real-world setting. All consecutive RRMM patients who received at least one cycle of ixazomib-based treatment combination between June 2013 and June 2018 were identified. Data was extracted from medical charts focusing on demographics, disease characteristics, prior treatment, and responses. Primary endpoint was progression-free survival (PFS); secondary endpoints included overall response rate (ORR), overall survival (OS), safety, and tolerability. A total of 78 patients across 7 sites were retrospectively included. Median follow-up was 22 months. Median age was 68 (range 38-90). Sixty-four percent received ixazomib in 2nd line, 19% in 3rd line. Overall, 89% of patients had been exposed to PIs (bortezomib 87%) prior to IRd, 41% to IMiDs. Twenty-nine (48%, of 60 available) had high (t(4:14), t(14:16), del17p) or intermediate (+1q21) risk aberrations. Most patients (82%) received ixazomib in combination with lenalidomide and dexamethasone. An exploratory assessment for disease aggressiveness at diagnosis was classified by a treating physician as indolent (rapid control to protect from target organ damage not required) vs aggressive (imminent target organ damage) in 63% vs 37%, respectively. Treatment was well tolerated, with a low discontinuation rate (11%). Median PFS on ixazomib therapy was 24 months (95% CI 17-30). PFS was 77% and 47% at 12 and 24 months, respectively. Median OS was not reached; OS was 91% and 80% at 12 and 24 months, respectively. Higher LDH, older age, and worse clinical aggressiveness were associated with worse PFS, whereas a deeper response to ixazomib (≥ VGPR) and a longer response to first-line bortezomib (≥ 24 m) were associated with an improved PFS on ixazomib. No effect on PFS was found for cytogenetic risk by FISH, ISS/rISS, and prior anti-myeloma treatment. Ixazomib-based combinations are efficacious and safe regimens in RRMM patients in the real-world setting, regardless to cytogenetic risk, with a PFS of 24 months comparable with clinical trial data. This regimen had most favorable outcomes among patients who remained progression-free more than 24 months after a bortezomib induction and for those who have a more indolent disease phenotype.

RESUMO

Therapy regimens for Chronic lymphocytic leukemia (CLL) commonly include chemotherapy and immunotherapy, which act through complement-mediated-cytotoxicity (CDC) and other mechanisms. CDC depends on several factors, including the availability and activity of the complement classical pathway (CP). Recently, a significant decrease in CP activity was shown to be associated with an immunoglobulin-C5a complex (Ig-C5a) and other markers of chronic CP activation in 40% of the patients. The study focused on the involvement of IgG-hexamers, an established CP activator, in the mechanism of chronic CP activation in CLL. Sera from 51 naïve CLL patients and 20 normal controls were collected. CP and alternative pathway (AP) activities were followed by the complement activity marker sC5b-9. Serum high molecular weight (HMW) proteins were collected by gel-filtration chromatography and their complement activation capacity was assessed. The levels of IgM, another established CP activator, were measured. Data were associated with the presence of Ig-C5a. Baseline levels of activation markers negatively correlated with CP and the AP activities, supporting chronic complement activation. In patients with Ig-C5a, HMW proteins that are not IgM, activated the complement. HMW proteins were identified as IgG-aggregates by affinity binding assays and Western blot analysis. The data indicate chronic CP activation, mediated by cell-free IgG-hexamers as a cause of decreased CP activity in part of the CLL population. This mechanism may affect immunotherapy outcomes due to compromised CP activity and CDC.

RESUMO

In recent years, considerable progress has been made in frontline therapy for elderly/physically unfit patients with CLL. The combination of obinutuzumab and chlorambucil (O-Clb) has been shown to prolong progression free survival (PFS, median PFS-31.5 months) and overall survival (OS) compared to chlorambucil alone. More recently, obinutuzumab given in combination with either ibrutinib or venetoclax improved PFS but not OS when compared to O-Clb. In this retrospective multinational, multicenter co-operative study, we evaluated the efficacy and safety of frontline treatment with O ± Clb in unfit patients with CLL, in a "real-world" setting. Patients with documented del (17p13.1)/TP53 mutation were excluded. A total of 437 patients (median age, 75.9 years; median CIRS score, 8; median creatinine clearance, 61.1 mL/min) were included. The clinical overall response rate was 80.3% (clinical complete and partial responses in 38.7% and 41.6% of patients, respectively). Median observation time was 14.1 months and estimated median PFS was 27.6 months (95% CI, 24.2-31.0). In a multivariate analysis, high-risk disease [del (11q22.3) and/or IGHV-unmutated], lymph nodes of diameter > 5 cm, obinutuzumab monotherapy and reduced cumulative dose of obinutuzumab, were all independently associated with shorter PFS. The median OS has not yet been reached and estimated 2-year OS is 88%. In conclusion, in a "real-world" setting, frontline treatment with O-Clb achieves PFS comparable to that reported in clinical trials. Inferior outcomes were noted in patients with del (11q22.3) and/or unmutated IGHV and those treated with obinutuzumab-monotherapy. Thus, O-Clb can be still considered as legitimate frontline therapy for unfit CLL patients with low-risk disease.

RESUMO

BACKGROUND: Invasive fungal diseases (IFD) are life-threatening infections most commonly diagnosed in acute leukaemia patients with prolonged neutropenia and are uncommonly diagnosed in patients with lymphoproliferative diseases. OBJECTIVES: Following the initial report of aspergillosis diagnosed shortly after beginning ibrutinib for chronic lymphocytic leukaemia, a survey was developed to seek additional cases of IFD during ibrutinib treatment. METHODS: Local and international physicians and groups were approached for relevant cases. Patients were included if they met the following criteria: diagnosis of chronic lymphocytic leukaemia/non-Hodgkin lymphoma; proven or probable IFD; and ibrutinib treatment on the date IFD were diagnosed. Clinical and laboratory data were captured using REDCap software. RESULT: Thirty-five patients with IFD were reported from 22 centres in eight countries: 26 (74%) had chronic lymphocytic leukaemia. The median duration of ibrutinib treatment before the onset of IFD was 45 days (range 1-540). Aspergillus species were identified in 22 (63%) of the patients and Cryptococcus species in 9 (26%). Pulmonary involvement occurred in 69% of patients, cranial in 60% and disseminated disease in 60%. A definite diagnosis was made in 21 patients (69%), and the mortality rate was 69%. Data from Israel regarding ibrutinib treated patients were used to evaluate a prevalence of 2.4% IFD. CONCLUSIONS: The prevalence of IFD among chronic lymphocytic leukaemia/non-Hodgkin lymphoma patients treated with ibrutinib appears to be higher than expected. These patients often present with unusual clinical features. Mortality from IFD in this study was high, indicating that additional studies are urgently needed to identify patients at risk for ibrutinib-associated IFD.

RESUMO

Hodgkin lymphoma (HL) is common in young adults and considered curable in most patients. Young HL survivors (HLS) are at risk of long-term adverse effects. Our study aimed to assess various fatigue and quality of life (QoL) complaints, and their correlations with treatment. Self-reported questionnaires assessing fatigue (MFI-20) and QoL-related issues (EORTC-QOL-C-30) were used to examine HLS aged 18-65 who completed first-line chemotherapy ± radiotherapy (RT) and were in complete remission for at least six months post-therapy. The cohort included 120 HLS (median age 32 years), assessed between 6 months and 15 years post-treatment. About 28% presented with severe fatigue and severely reduced QoL. Higher fatigue levels were associated with four cycles of the ABVD + RT. Young HLS experience high levels of persistent physical fatigue, emotional distress, and cognitive decline that are insufficiently investigated. Assessment of these complaints is essential and further investigation may provide tailored solutions for a better QoL for HLS.

RESUMO

BACKGROUND: Chronic lymphocytic leukemia (CLL) is frequently accompanied by immune dysregulation. AIMS: In this multicenter prospective study, we investigated whether heavy + light chains (HLC: IgGκ, IgGλ, IgAκ, IgAκ, IgMκ, IgMλ) and IgG subclasses (IgG1, IgG2, IgG3, and IgG4) could be used as novel prognostic markers of immunoparesis in 105 treatment-naïve patients with CLL. RESULTS: Heavy + light chains immunoparesis of ≥1, ≥2, and ≥3 isotypes was evident in 74 (70%), 58 (55%), and 36 (34%) patients, respectively. Severe HLC immunoparesis was identified in 40 (38%) patients. Of the IgG subclasses, IgG1 and IgG2 were most frequently suppressed, affecting 46 (44%) and 36 (34%) patients, respectively; 63 (60%) patients had low levels of at least one IgG subclass. In multivariate analysis, severe HLC immunoparesis (hazard ratio [HR]: 36.5; P = .010) and ΣFLC ≥ 70 mg/L (HR: 13.2; P = .004) were the only factors independently associated with time to first treatment (TTFT). A risk model including these variables identified patients with 0, 1, and 2 risk factors and significantly different TTFT (P < .001). Patients with two factors represented an ultra-high-risk group with a median TTFT of only 1.3 months. CONCLUSION: The above findings demonstrate the potential for the use of HLC immunoparesis, together with sFLC measurements, as future prognostic biomarkers in CLL.

RESUMO

BACKGROUND: Major advances in the treatment of patients with hairy cell leukemia (HCL) have been made following the introduction of purine analogues. The major significant short-term toxicity of cladribine therapy are neutropenia and neutropenic fever (NF) which may be life-threatening. AIM: In this retrospective study, we compared the incidence and duration of neutropenia and hospitalization in patients with HCL treated with cladribine followed by peg-filgrastim as primary prophylaxis versus daily filgrastim given "on demand" according to absolute neutrophil count (ANC). METHODS: Medical records of patients with HCL diagnosed and followed in 12 medical centers in Israel during 1985-2015 were examined for details of disease at diagnosis. The efficacy of peg-filgrastim and filgrastim was assessed by evaluating the incidence of neutropenia (ANC < 1.0 × 10 [9]/L), number and length of hospitalizations, and number of days from the last day of therapy to recovery of ANC to >1.0 × 10 [9]/L. RESULTS: The study population included 202 patients with HCL, 159 of whom (80.7%) were treated with cladribine; 78 patients (49%) required hospitalization for the administration of broad-spectrum antibiotics due to NF. Twenty-eight (19%) patients were treated with peg-filgrastim as primary prophylaxis, while 74 (64%) received filgrastim "on demand" due to neutropenia. Median length of hospitalization, and nadir duration were 8 and 18 days respectively (p = 0.71, p = 0.44). CONCLUSIONS: Infectious complications post-cladribine treatment remain high. No difference was found in terms of incidence of NF, number of febrile days, and nadir duration in patients receiving primary peg-filgrastim prophylaxis compared to filgrastim given on demand. Both approaches are justifiable, and the choice remains at the physician's discretion.

RESUMO

BACKGROUND: The importance of emotional intelligence (EI) to the success of health professionals has been increasingly acknowledged. Concurrently, medical schools have begun integrating non-cognitive measures in candidate selection processes. The question remains whether these newly added processes correctly assess EI skills. OBJECTIVES: Measuring EI levels among medical students; examining the correlations between participants' EI levels and their scores on the non-cognitive MOR test; and exploring students' attitudes regarding the importance of EI in medical practice. METHODS: The study included 111 first-year and sixth-year students at the Faculty of Medicine at the Technion, Haifa, Israel. Emotional intelligence was assessed by the Bar-On EQ-i 2.0, and MOR evaluation scores were provided by the faculty. An additional questionnaire was designed to rate students' attitudes toward the importance of EI to the success of medical doctors (MDs). RESULTS: No significant correlations were found between MOR test scores and EI evaluation scores. Of the 15 EI competencies evaluated, mean scores for flexibility, problem-solving, and independence were lowest for both the first-year and the sixth-year study groups. No differences in EI levels between first-year and sixth-year students were found. Both groups of students considered EI to be highly important to their success as MDs. CONCLUSIONS: While further studies of the links between MOR tests and EI are required, the current findings indicate that MOR test scores may not be predictive of medical students' EI levels and vice versa. As previous evidence suggests that EI contributes to professional success and to better outcomes in the field of medicine, integrating it into selection processes for medical students and into the curricula in medical schools is recommended.

RESUMO

Chronic lymphocytic leukemia (CLL) is a disease of elderly patients. The fludarabine, cyclophosphamide, and rituximab (FCR) regimen is considered the treatment of choice for young fit patients with CLL; however, this combination is toxic for older patients. At the time this study was first planned and initiated, there was no standard chemo-immunotherapy regimen regarded as standard therapy for the less fit elderly patient with CLL. Here, we conducted a single-arm, phase II trial to examine the efficacy and safety of lower-dose fludarabine and cyclophosphamide combined with a standard dose of rituximab (LD-FCR) in elderly patients with previously untreated CLL. Forty patients received LD-FCR and were included in the efficacy analysis. Two patients treated with FC alone were only included in the safety analysis. The median age was 72.7 years (range, 65.0 to 85.0). The overall response and complete response rates were 67.5% and 42.5%, respectively. Median progression-free survival (PFS) was 35.5 months (95% CI, 29.27-41.67). Two patients (4.8%) died during the study period. Hematological toxicities and infections were the most common complications encountered; grade 3 to 4 treatment-related neutropenia occurred in 20 (47.6%) patients. During the entire study follow-up, 26 patients (61.9%) had all grades of infection including six (14.3%) with neutropenic fever and eight (19%) with grade 3 to 4 non-neutropenic infections. In conclusion, LD-FCR is an effective and relatively safe regimen for previously untreated patients with CLL. It has the advantage of being both "time and cost limited" and, even in the era of novel agents, can still be considered when planning treatment for elderly patients without high-risk biomarkers. However, recent results in fit elderly patients using the combination of bendamustine and rituximab which have achieved longer PFS with good safety profile must be taken into consideration in this regard.

RESUMO

Chronic lymphocytic leukemia (CLL) is the most common adult leukemia in the Western world. The therapeutic approach to CLL includes chemotherapeutic regimens and immunotherapy. Complement-mediated cytotoxicity, which is one of the mechanisms activated by the therapeutic monoclonal antibodies, depends on the availability and activity of the complement (C) system. The aim was to study the structure of circulating C components and evaluate the importance of C5 structural integrity for C activity in CLL patients. Blood samples were collected from 40 naïve CLL patients and 15 normal controls (NC). The Western blot analysis showed abnormal C5 pattern in some CLL patients, while patterns of C3 and C4 were similar in all subjects. Levels of the C activation markers sC5b-9 and C5a were quantified before and after activation via the classical (CP) and alternative (AP) pathways. In patients with abnormal C5, basal levels of sC5b-9 and C5a were increased while activities of the CP and of the CP C5-convertase, the immediate C5-upstream complex, were decreased compared to NC and to patients with normal C5. The data indicate a link between CP activation and apparent C5 alterations in CLL. This provides a potential prognostic tool that may personalize therapy by identifying a sub-group of CLL patients who display an abnormal C5 pattern, high basal levels of sC5b-9 and C5a, and impaired CP activity, and are likely to be less responsive to immunotherapy due to compromised CP activity.

RESUMO

It is well established that some patients with diffuse large B-cell lymphoma (DLBCL) and the negative end of treatment PET-CT (EOT-PET-CT) will relapse, while a proportion with positive uptake can still obtain long-term EFS. We reviewed data of 200 consecutive, previously untreated patients with DLBCL recorded in Italy and Israel between 2007 and 2015. We found that patients with negative EOT-PET-CT with AMC > 630/mmc have a 3-years EFS of 72%, compared to those with AMC ≤ 630/mmc that have an EFS of 84%. Furthermore, considering patients with positive EOT-PET-CT, those with AMC > 630/mmc have a 3-years EFS of 8%, while those with AMC ≤ 630/mmc have an EFS of 38%. Thus, it appears that combining the gold standard for response evaluation EOT-PET-CT with a simple and inexpensive parameter like AMC at diagnosis, further improves prognostication in DLBCL. Applying this simple method can be useful for all doctors working in lymphoma clinical practice.

RESUMO

BACKGROUND/AIM: In this retrospective study, we summarized the national Israeli experience with hairy cell leukemia (HCL) in a large cohort of patients with a long follow-up. PATIENTS AND METHODS: Demographic data, and relevant laboratory and clinical parameters were analyzed, emphasizing the outcome after first-line treatment with cladribine. RESULTS: Data on 203 patients was collected from 12 medical centers during 1985-2015. Mean and median follow-up were 7.5 years and 5.18 years (interquartile range=0.1-40 years), and 5- and 10-year survival were 96% and 90.62%, respectively. The median age of diagnosis was 55.5 years for Jews and 49 years for Arabs (p=0.021), and most patients were males (81.77%); 52.2% were Ashkenazi Jews, 36.1% Sephardic Jews and 11.7% were Arab, Druze or other ethnicity. Cladribine was given to 159 patients (80.7%%) and most (62%) received intravenous (i.v.) and 38% received subcutaneous (s.c.) therapy. Overall survival and time to next treatment were not significantly different between the two schedules (i.v., s.c.). In univariate analysis of a variety of factors, only age >65 years had a negative impact on outcome, with shorter overall survival. It is of interest that Arab patients with HCL were diagnosed at an earlier age, but had a similar clinical course and outcome to both Ashkenazi and Sephardic Jews.

RESUMO

BACKGROUND/AIM: In chronic lymphocytic leukemia (CLL) the absolute neutrophil count (ANC) has generally been reported to be within normal limits and leukocytosis is due to absolute lymphocytosis. However, other cell types such as neutrophils and monocytes may also exceed the normal range in this disorder. The aim of this retrospective study was to evaluate the frequency and prognostic value of neutrophilia defined as an ANC>7×109/l and monocytosis- an absolute monocyte count (AMC)>1×109/l in 113 patients with chronic lymphocytic leukemia (CLL). MATERIALS AND METHODS: We analyzed clinical and laboratory data from the records of patients with CLL followed in the Hematology unit of a tertiary hospital in Israel. Patients were categorized according to their ANC and AMC before treatment and their data compared. RESULTS: In 24 (21%) patients, neutrophilia was present at diagnosis while 40 (35%) had monocytosis. We identified that 9% of cases had neutrophilia with normal AMC. This subgroup of patients had a better prognosis with lower mortality rate, longer time-to-treatment interval and a higher rate of complete or partial response to treatment compared to patients without neutrophilia or monocytosis. CONCLUSION: The presence of neutrophilia without monocytosis before treatment appears to be associated with a more favorable prognosis in CLL. These observations still need to be confirmed and validated in a larger cohort of patients.

RESUMO

Cancer-related cognitive impairment (CRCI) is commonly reported post-chemotherapy in adults with solid tumours. Hodgkin lymphoma (HL) mostly affects young adults. Data regarding CRCI in HL survivors (HLS) are scarce. The current study aimed to objectively assess CRCI incidence and characteristics in HLS. HLS, who completed first-line (chemotherapy ± radiation) therapy and remained in complete remission for 6 months to 5 years from therapy end, were evaluated. Age- and education-matched healthy individuals served as controls (n = 14). Test results were compared to population norms and healthy controls. Study participants completed self-reported questionnaires evaluating fatigue, depression, anxiety, quality of life and cognitive function. Subjects underwent neurocognitive evaluation, assessing processing speed, memory, attention, executive functions and intelligence domains. The present study included 51 HLS with a median age of 28 years, mean education of 14·5 ± 2·5 years. Complaints related to cognitive deterioration and fatigue were significantly more severe and frequent in HLS compared to healthy controls. Objective neurocognitive evaluation demonstrated that 30% of HLS were impaired in ≥2 cognitive domains. In conclusion, the present study demonstrates that fatigue and cognitive impairment, predominantly in executive functions and memory, constitute frequent and alarming findings in HLS. These adverse effects can persist and exert an impact on all aspects of life.

RESUMO

This is a pivotal, multicenter, open-label study of moxetumomab pasudotox, a recombinant CD22-targeting immunotoxin, in hairy cell leukemia (HCL), a rare B cell malignancy with high CD22 expression. The study enrolled patients with relapsed/refractory HCL who had ≥2 prior systemic therapies, including ≥1 purine nucleoside analog. Patients received moxetumomab pasudotox 40 µg/kg intravenously on days 1, 3, and 5 every 28 days for ≤6 cycles. Blinded independent central review determined disease response and minimal residual disease (MRD) status. Among 80 patients (79% males; median age, 60.0 years), durable complete response (CR) rate was 30%, CR rate was 41%, and objective response rate (CR and partial response) was 75%; 64 patients (80%) achieved hematologic remission. Among complete responders, 27 (85%) achieved MRD negativity by immunohistochemistry. The most frequent adverse events (AEs) were peripheral edema (39%), nausea (35%), fatigue (34%), and headache (33%). Treatment-related serious AEs of hemolytic uremic syndrome (7.5%) and capillary leak syndrome (5%) were reversible and generally manageable with supportive care and treatment discontinuation (6 patients; 7.5%). Moxetumomab pasudotox treatment achieved a high rate of independently assessed durable response and MRD eradication in heavily pretreated patients with HCL, with acceptable tolerability.
