Clofarabine (CLO) and cyclophosphamide (CY) combinations were tested in late stage refractory/relapsed (R/R) acute lymphoblastic leukemia (ALL) with disappointing results and high-grade toxicity. We designed a sequential 5-day combination of CLO 40 mg/m

In Ph+ acute lymphoblastic leukaemia (Ph+ ALL), minimal residual disease (MRD) is the most relevant prognostic factor. Currently, its evaluation is based on quantitative real-time polymerase chain reaction (Q-RT-PCR). Digital droplet PCR (ddPCR) was successfully applied to several haematological malignancies. We analyzed 98 samples from 40 Ph+ ALL cases, the majority enrolled in the GIMEMA LAL2116 trial: 10 diagnostic samples and 88 follow-up samples, mostly focusing on positive non-quantifiable (PNQ) or negative samples by Q-RT-PCR to investigate the value of ddPCR for MRD monitoring. DdPCR BCR/ABL1 assay showed good sensitivity and accuracy to detect low levels of transcripts, with a high rate of reproducibility. The analysis of PNQ or negative cases by Q-RT-PCR revealed that ddPCR increased the proportion of quantifiable samples (p

Adolescents and young adults (AYA) with acute lymphoblastic leukemia (ALL) represent a unique patient population with specific characteristics and needs. Growing evidences suggest that pediatric-inspired approaches improve the outcome in AYA. These results prompted the design of a pediatric AIEOP-BFM ALL 2000-based regimen - the GIMEMA LAL-1308 protocol - for newly diagnosed AYA (range 18-35 years) with Philadelphia negative (Ph-) ALL. The protocol included minimal residual disease (MRD) analysis at two different time-points (TP), that is, at the end of induction IA and consolidation IB, and a modulation in post-consolidation intensity according to MRD. Seventy-six patients were eligible between September 2010 and October 2014. The regimen was well tolerated, with 2.7% induction deaths and no deaths in the post-consolidation phase. The complete response (CR) rate was 92%; the 48-month overall survival (OS) and disease-free survival (DFS) were 60.3% and 60.4%. Both OS and DFS were significantly better in T-ALL than B-ALL.

Early recognition of Philadelphia-like (Ph-like) acute lymphoblastic leukemia (ALL) cases could impact on the management and outcome of this subset of B-lineage ALL. In order to assess the prognostic value of the Ph-like status in a pediatric-inspired, minimal residual disease (MRD)- driven trial, we screened 88 B-lineage ALL cases negative for major fusion genes (BCR-ABL1, ETV6-RUNX1, TCF3-PBX1 and KTM2Ar) enrolled in the GIMEMA LAL1913 front-line protocol for adult BCR/ABL1-negative ALL. The screening - performed using the “BCR/ABL1-like predictor” - identified 28 Ph-like cases (31.8%), characterized by CRLF2 overexpression (35.7%), JAK/STAT pathway mutations (33.3%), IKZF1 (63.6%), BTG1 (50%) and EBF1 (27.3%) deletions, and rearrangements targeting tyrosine kinases or CRLF2 (40%). The correlation with outcome highlighted that: i) the complete remission rate was significantly lower in Ph-like compared to non-Phlike cases (74.1% vs. 91.5%, P=0.044); ii) at time point 2, decisional for transplant allocation, 52.9% of Ph-like cases versus 20% of non-Ph-like were MRD-positive (P=0.025); iii) the Ph-like profile was the only parameter associated with a higher risk of being MRD-positive at time point 2 (P=0.014); iv) at 24 months, Ph-like patients had a significantly inferior event-free and disease-free survival compared to non-Ph-like patients (33.5% vs. 66.2%, P=0.005 and 45.5% vs. 72.3%, P=0.062, respectively). This study documents that Ph-like patients have a lower complete remission rate, event-free survival and disease-free survival, as well as a greater MRD persistence also in a pediatric-oriented and MRD-driven adult ALL protocol, thus reinforcing that the early recognition of Ph-like ALL patients at diagnosis is crucial to refine risk-stratification and to optimize therapeutic strategies.

Introduction: Recent advances in prognostication as well as management of Follicular Lymphoma (FL) are moving to personalized approach. Areas covered: Prognostic scores as well as consolidated and innovative therapeutic approaches are evaluated according to the various presentation modalities. For asymptomatic, low-tumor burden FL, a ‘watch and wait’ policy is currently the first-choice approach, although possible alternatives are discussed. Early stage FL may be treated with local radiotherapy although the role of minimal residual disease in possible additional agents should be determined. The first line treatment for symptomatic FL is chemo-immunotherapy followed by two years maintenance therapy with anti-CD20 monoclonal antibodies. A deeper knowledge of FL biology has opened new perspectives regarding the timing of therapy and has offered new targets for the development of novel agents that aim to change the therapeutic scenario of FL management. Expert commentary: The introduction of novel agents could question the incurability of FL and change the therapeutic goal from prolonging the complete remission state to eradicating the disease in young/fit patients, as well as improving quality of life in elderly/unfit patients. In the near future, combining new biologic agents and adoptive cell therapies could help in achieving these aims.

Background. The management of adult patients with Ph+ acute lymphoblastic leukemia (Ph+ ALL), including the elderly, has changed since the introduction of tyrosine kinase inhibitors (TKI). A significantly better survival is observed in patients who become minimal residual disease (MRD)-negative. Aims. To increase the rate of MRD-negative patients, we designed a front-line chemo-free induction-consolidation trial (D-ALBA, GIMEMA LAL2116) based on the combination of the second-generation TKI dasatinib with the bispecific monoclonal antibody blinatumomab. The primary endpoint of the study was the rate of patients who achieved a complete molecular remission (CMR) or a positive non-quantifiable (PNQ) disease after at least two cycles of blinatumomab. Secondary endpoints included disease-free survival (DFS), overall survival (OS), cumulative incidence of relapse (CIR) and safety. We also sought to evaluate the prognostic impact of additional genomic lesions - performed on diagnostic samples - and the potential changes in the immunologic compartment, in terms of T cells and T-regulatory cells (Tregs), evaluated by flow cytometry (CD3+/CD4+, CD3+/CD8+ and CD3+/CD4+/CD25+/FOXp3+, respectively). Methods. This multicenter phase II study enrolled Ph+ ALL patients aged 18 years or older, with no upper age limit. Prior to dasatinib, patients received a 7-day steroids pre-phase: steroids were continued for further 24 days and stopped at day 31. Dasatinib (140 mg/day) was administered as induction for 85 days. Thereafter, patients who obtained a complete hematologic response (CHR) received a post-induction consolidation treatment with blinatumomab at a flat dose of 28 μg/day. A minimum of 2 cycles was mandatory, while the administration of up to 3 additional cycles was allowed based on the response to blinatumomab and medical decision. Dasatinib was continued during treatment with blinatumomab. CNS prophylaxis was carried out during the whole treatment. Post-consolidation treatment was open. Results. Between May 2017 and January 2019, 63 patients have been enrolled. Median age was 54.5 years (range: 24.1-81.7), 54% were female, the median white blood cell count (WBC) was 42 x109/l (range: 0.63-63.5) and 65.1% carried the p190 fusion. Copy number aberration analysis showed that the most frequent lesion was, as expected, IKZF1 deletion (54%): 23.9% of patients were thus classified as IKZF1plus (i.e. IKZF1 and/or PAX5 and/or CDKN2A/B deletions). The median follow-up is 10 months (range: 0.9-21.5). So far, 61 patients have completed induction, 55 the 1st cycle of blinatumomab, 47 the 2nd cycle, 33 the 3rd, 26 the 4th and 17 the 5th. Two patients have gone off protocol for medical decision and toxicity, and 1 died during induction. At the end of the induction with dasatonib, 17/58 pts (29.3%) had a molecular response (6 CMR and 11 PNQ). At the primary endpoint (end of the 2nd cycle of blinatumomab), 27/47 (56.3%) had a molecular response (17 CMR and 10 PNQ). The rates of molecular responses further increased after subsequent cycles of blinatumomab: 65.7% after the 3rd cycle and 80% after the 4th cycle. ABL1 mutational analysis was carried out in 15 patients with evidence of a MRD increase: 8 cases were WT, while mutations were detected in 7 (6 T315I, and 1 E255K). All mutations but 1 occurred prior to the start of blinatumomab and all were "cleared" by blinatumomab. The analysis of the immunologic compartment carried out in 12 patients who completed all 5 cycles of blinatumomab showed a significant increase in the rate of CD8+ T cells (19.8% before the start of blinatumomab and 29% after the 5th cycle, p=0.04) and a significant reduction in the rate of Tregs (11% before blinatumomab and 3.7% after the 5th cycle, p=0.02). Overall, 5 relapses have been recorded (2 hematologic, 2 isolated CNS and 1 nodal). The 12-month OS and DFS are 94.2% and 87.8%. A significantly inferior DFS (61.4%, p=0.01) was observed in IKZF1plus cases: these patients were prone to develop deleterious mutations. So far, 12 patients have been allografted and no transplant-related mortality has been recorded. Conclusions. In the first chemo-free induction-consolidation protocol for adult Ph+ ALL patients of all ages based on a combination of a targeted and immunotherapeutic strategy, the rates of molecular responses and survival are highly promising; patients harboring IKZF1 plus represent, also in this setting, a clinical challenge.

Many epidemiological, biological and therapeutic studies have extensively investigated the etiological link between HCV infection and B-cell Non-Hodgkin Lymphoma (NHL). Large experiences in the literature demonstrated HCV-related indolent NHL regression after antiviral therapy. While the response to interferon-ribavirin-based antiviral therapy is well documented, evidence of the efficacy of interferon-free Direct-Acting Antivirals (DAAs) in this subset of lymphoma is also currently increasing. Splenic and Nodal Marginal zone Lymphoma (MZL) are frequently associated with HCV chronic infection. In this article we report two cases of HCV-related MZL with an unusual presentation, subcutaneous “lipoma-like” nodules, treated with DAAs. Both patients, a 59-years-old woman and a 72-years-old man, were affected by HCV chronic infection since several years and were referred to our Institute for a diagnosis of MZL with subcutaneous presentation. Given the possible etiological link with HCV infection, both patients were treated with DAAS. A Sustained virological response (SVR) was reached after few weeks of therapy and at the end of treatment a clinically and radiologically documented reduction of MZL localizations, persisting to date, were obtained in both patients. The two clinical cases presented in this article confirm the efficacy of DAA’s as first-line treatment in HCV related NHL, also in this rare entity of MZL with subcutaneous presentation.

Infections by Carbapenem-Resistant Enterobacteriaceae (CRE), in particular carbapenem-resistant Klebsiella pneumoniae (CRKp), are a significant public health challenge worldwide. Resistance to carbapenems in enterobacteriaceae is linked to different mechanisms, in particular the production of different types of enzymes including KPC, VIM, IMP, NDM, and OXA-48. Despite several attempts to control the spread of these infections at local and national level, epidemiological situation for CRKp had worsened in the last years in the Mediterranean area. The rate and types of CRKp isolates greatly differ in the various Mediterranean countries. KPC-producing K.pneumoniae is diffused particularly in the European countries bordering the Mediterranean sea and is actually endemic in Greece and Italy. On the contrary, OXA-48-producing K.pneumoniae is endemic in Turkey and Malta, and diffused at inter-regional level particularly in some north African and Middle East countries. The spread of these multiresistant pathogens in the world and the Mediterranean countries has been related to various epidemiological factors including the international transfer of patients coming from endemic areas.
