Predictors of Response to Hydroxyurea and Switch to Ruxolitinib in HU-Resistant Polycythaemia VERA Patients: A Real-World PV-NET Study.

In polycythemia vera (PV), the prognostic relevance of an ELN-defined complete response (CR) to hydroxyurea (HU), the predictors of response, and patients' triggers for switching to ruxolitinib are uncertain. In a real-world analysis, we evaluated the predictors of response, their impact on the clinical outcomes of CR to HU, and the correlations between partial or no response (PR/NR) and a patient switching to ruxolitinib. Among 563 PV patients receiving HU for ≥12 months, 166 (29.5%) achieved CR, 264 achieved PR, and 133 achieved NR. In a multivariate analysis, the absence of splenomegaly (p = 0.03), pruritus (p = 0.002), and a median HU dose of ≥1 g/day (p < 0.001) remained associated with CR. Adverse events were more frequent with a median HU dose of ≥1 g/day. Overall, 283 PR/NR patients (71.3%) continued HU, and 114 switched to ruxolitinib. In the 449 patients receiving only HU, rates of thrombosis, hemorrhages, progression, and overall survival were comparable among the CR, PR, and NR groups. Many PV patients received underdosed HU, leading to lower CR and toxicity rates. In addition, many patients continued HU despite a PR/NR; however, splenomegaly and other symptoms were the main drivers of an early switch. Better HU management, standardization of the criteria for and timing of responses to HU, and adequate intervention in poor responders should be advised.

Immunotactoid glomerulopathy and chronic lymphocytic leukemia: The need for a multidisciplinary approach.

Chronic lymphocytic leukemia (CLL) is the most common type of leukemia in western countries. The association between CLL and glomerular disease (GD) is rare. The most frequent GD associated with CLL is membranoproliferative membranous glomerulonephritis (GN) (MPGN) (45%) types I and II, followed by membranous glomerulonephritis, with the same reports of immunotactoid glomerulopathy (ITG). We report a case of ITG diagnosed on kidney biopsy in a CLL patient and the response of renal parameters to drug treatment for CLL. The patient was treated with several lines of therapies with a good response.

Correspondence in reference to the previously published manuscript: Reduction of cycles of bendamustine plus rituximab therapy in the cases with good response for indolent B-cell lymphomas.

Takezaki et al. analyzed the outcome of 57 patients with indolent lymphomas treated with Bendamustine plus Rituximab (BR) according to the number of cycles received, showing that patients who discontinued BR after four cycles had similar outcomes compared to patients who received five or six cycles. Considering the similarities but also the differences between indolent lymphomas and chronic lymphocytic leukemia (CLL), we enriched the results obtained with a cohort of CLL patients treated with BR starting from the experience of the Lazio region group on CLL. Out of 115 patients, 97 (84%) received 4-6 cycles of BR, while 18 (16%) received 1-3 cycles. The outcome of the group of patients who received at least 4 cycles was superior in terms of response rate (ORR 96% vs. ORR 83%, p = 0.041; CR 58% vs. CR 28%, p = 0.052 respectively) and PFS [median PFS 52.6 (40.3-64.9) versus 26.2 (19.3-33.0) months, p < 0.001]. The number of patients undergoing 4 cycles of BR (4-cycles group) and 5-6 cycles (over-4-cycles group) was 9 and 88, respectively. Compared to analysis conducted by the Japanese group in indolent lymphomas, in CLL we did not observe any difference between the outcome of the 4-cycles group and the over-4-cycles group in terms of ORR (89% vs. 97%, p = 0.268) and in survival [median PFS 40.8 (13.7-67.8) versus 52.6 (38.7-66.5) months, p = 0.117]. Moreover, we observed that patients who achieved a clinical CR showed overlapping outcomes with patients who received more than 4 cycles [CR vs. non-CR median PFS not reached vs. 11.0 months; over-4-cycles group median PFS 52.6 months (40.3-64.9); p < 0.001]. Nowadays chemoimmunotherapy with BR is reserved to fit elderly CLL patients, and there are many chemo-free treatment options available; therefore, discontinuation after 4 cycles may be permissible in patients who obtained a CR in order to limit toxicity as much as possible.

Daratumumab combined with dexamethasone and lenalidomide or bortezomib in relapsed/refractory multiple myeloma (RRMM) patients: Report from the multiple myeloma GIMEMA Lazio group.

The multiple myeloma (MM) treatment has changed over the last years due to the introduction of novel drugs. Despite improvements in the MM outcome, MM remains an incurable disease. Daratumumab is a human IgGK monoclonal antibody targeting CD38 with tumor activity associated with immunomodulatory mechanism. In combination with standard of care regimens, including bortezomib (Vd) or lenalidomide (Rd), daratumumab prolonged progression-free survival (PFS) in patients (pts) with relapsed/refractory multiple myeloma (RRMM) and in new diagnosis MM. We report the data of the MM GIMEMA Lazio group in 171 heavily treated pts who received daratumumab, lenalidomide and dexamethasone (DRd) or daratumumab, velcade and dexamethasone (DVd). The overall response rate was 80%, and the overall survival (OS) and PFS were 84% and 77%, respectively. In addition, pts treated with DRd showed a better median PFS compared to pts treated with DVd, at 12 and 24 months, respectively. The most common hematologic treatment-emergent adverse events (TAEs) were neutropenia, thrombocytopenia, and anemia. The most common nonhematologic TAEs were peripheral sensory neuropathy and infections. Our data confirmed that DRd or DVd therapy is effective and safe in RRMM pts, and our real-life analysis could support the physicians regarding the choice of optimal therapy in this setting of pts.

Safety and effectiveness of ruxolitinib in the real-world management of polycythemia vera patients: a collaborative retrospective study by pH-negative MPN latial group.

Ruxolitinib is approved for polycythemia vera (PV) patients after failure to previous cytoreductive therapy, based on durable results observed in phase 3 trials. We report a multicenter retrospective study demonstrating the efficacy and safety of ruxolitinib in real-life setting. Eighty-three patients were evaluated. Median follow-up was 24.5 months (IQR 14.0-29.3). At a 3-month response assessment, ruxolitinib provided significant benefit in reducing hematocrit (HCT) level (p < 0.001), phlebotomy requirement (p < 0.001), leucocytes (p = 0.044), and disease-related symptoms (p < 0.001). The exposure-adjusted rates (per 100 patient-years) of infectious complications, thromboembolic events, and secondary malignancies were 6.9, 3, and 3.7, respectively. Non-melanoma skin cancers (NMSC) were the most frequent (40%) SM type. Lymphoproliferative disorders were not detected. Five (6%) patients permanently discontinued ruxolitinib treatment and four (5%) evolved in myelofibrosis (MF), but none in acute leukemia. The rate of MF evolution per 100 patient-years of exposure was 2.8. In our experience, ruxolitinib confirmed its efficacy and safety outside of clinical trials.

Front-Line Therapy for Elderly Chronic Lymphocytic Leukemia Patients: Bendamustine Plus Rituximab or Chlorambucil Plus Rituximab? Real-Life Retrospective Multicenter Study in the Lazio Region.

Previous studies investigated the efficacy and the safety of bendamustine (B) vs. chlorambucil (Chl) associated with rituximab (R) in fludarabine-ineligible patients with treated and untreated chronic lymphocytic leukemia (CLL). We conducted a retrospective multicenter study in the Lazio region to further evaluate and compare the efficacy and the toxicity of Chl-R and B-R regimen in CLL patients over the age of 65. We enrolled 192 untreated CLL patients: 111 treated with B-R and 81 with Chl-R. The overall response rates (ORR; 93.6% in B-R and 86.5% in Chl-R) were not statistically different between the two groups, such as progression-free survival (PFS), time to retreatment (TTR), and overall survival (OS). The B-R group showed a higher hematological (p = 0.007) and extra-hematological (p = 0.008) toxicity. When comparing the toxicities according to age, we noted that the extra-hematological toxicity was higher in patients over the age of 75 who were treated with B-R than those treated with Chl-R (p = 0.03). This retrospective study confirms the feasibility of B-R and Chl-R in elderly untreated CLL patients. Currently, patients who are over 75 and unfit are usually treated with Chl-R. This scheme allows achieving the same ORR, PFS, TTR, and OS when compared with B-R because of hematological and extra-hematological toxicities due to B, in which a greater dose reduction has been shown in comparison to Chl.

Anagrelide in Essential Thrombocythemia (ET): Results from 150 patients over 25 years by the "Ph1-negative Myeloproliferative Neoplasms Latium Group".

BACKGROUND AND AIMS: Anagrelide is a drug effective in reducing platelet counts in essential thrombocythemia (ET) and Ph1-negative myeloproliferative neoplasms. The aim of this study was to evaluate the real-life use of anagrelide in patients with ET followed over 25 years at the Haematological Institutes belonging to "Ph1-negative Myeloproliferative Neoplasms Latium Group." PATIENTS AND METHODS: Eligibility criteria were diagnosis of ET and treatment with anagrelide. Data were collected through an ad hoc case report form. RESULTS: One hundred and fifty patients received anagrelide for a median time of 7.4 years (0.1-23.2). Anagrelide was administered as first-line therapy in 34.7% of patients, as second-line in 52% and as third-line in 13.3%: 85.4% responded to therapy. Sixty-eight/136 evaluable patients reported side effects: palpitations, peripheral vasodilation, anaemia, diarrhoea and gastric distress. Fourteen thrombotic (arterial 10, venous 4) and 51 bleeding events (minor 48, major 3) occurred. Sixteen/150 (10.6%) patients developed secondary myelofibrosis and 3/150 (2%) an acute myeloid leukaemia. CONCLUSIONS: In our experience, anagrelide is an effective drug in reducing platelet levels in a high percentage of patients with ET. It is especially addressed to younger people. A careful assessment of the thrombotic risk and monitoring of cardiac function, at diagnosis and during follow-up, is mandatory.

Preliminary results of a counselling programme for fertility preservation in female cancer patients: The experience of the GEMME DORMIENTI network.

OBJECTIVE: To describe a population of patients referred for fertility preservation (FP), how to efficiently provide FP care, and how FP care changed over time. METHODS: This longitudinal observational study enrolled 281 female cancer patients referred between 2013 and 2016 to the non-profit organisation Gemme Dormienti ONLUS (GD) for FP care. All patients underwent the same battery of instrumental and laboratory diagnostic tests. GnRHa therapy was started at least seven days before CTh treatment. RESULTS: From 2013 to 2016, we observed a progressive increase in the number of patients referred for FP care. Out of 251 eligible patients, 135 patients were treated with GnRHa only, and 72 patients underwent GnRHa therapy and cryopreservation. The median time from GD referral to oocyte and ovarian tissue cryopreservation was 11 and 5 days respectively. Tissue cryopreservation requests increased during our study period (from four cases in 2013 to 17 cases in 2016). During follow-up, 17ß-estradiol and FSH levels were significantly increased (p < .0001), and AMH levels were significantly decreased (p < .0001). CONCLUSION: The rapid increase in the number of patients who requested FP care and in the complexity of FP procedures overtime reflects the need to improve quality of life for cancer patients.

The neutrophil/lymphocyte ratio ≥3.5 is a prognostic marker in diffuse large B-cell lymphoma: a retrospective analysis from the database of the Italian regional network 'Rete Ematologica del Lazio per i Linfomi' (RELLI).

In solid tumors and lymphomas, the neutrophil/lymphocyte (N/L) ratio at diagnosis has been shown to be a prognostic factor. The aim of our study was to validate the originally reported N/L ratio cut-point of 3.5 in patients with diffuse large B-cell lymphoma (DLBCL) registered in an Italian real-life database. The prognostic role of the N/L ratio at diagnosis on event-free survival (EFS) and overall survival (OS) was assessed in 505 patients with DLBCL. Patients with an N/L ratio <3.5 (n = 249) had a 4-year EFS probability of 76% and OS probability of 86%, significantly higher than the 4 year EFS rate of 48% and OS rate of 64% in patients with N/L ratio ≥3.5 (n = 256, both p<.0001). The N/L ratio was an independent prognostic factor in the multivariate analysis including the IPI score, and could separate patients with a low/intermediate risk IPI (IPI <3).

Treatment of Philadelphia-negative myeloproliferative neoplasms in accelerated/blastic phase with azacytidine. Clinical results and identification of prognostic factors.

There have been some reports on a possible role of azacytidine (AZA) in the treatment of accelerated/blastic phase evolved from Philadelphia-negative myeloproliferative neoplasms (MPN-AP/BP), but results are conflicting. In this study, we analyzed a cohort of 39 patients with MPN-AP/BP treated frontline with AZA at the standard dosage (75 mg/m2 ). Median time from diagnosis to AP/BP evolution was 92.3 months (IR 29.9-180.1). All patients were evaluable for hematologic response: two patients (5.2%) died early after AZA initiation, 13 patients (33.3%) had a progressive or stable disease, nine (23.1%) had a hematologic improvement (HI), seven (17.9%) achieved a partial response (PR), and eight (20.5%) a complete response (CR). Overall, 24 patients achieved a clinical hematologic response (HI + PR + CR), with an overall response rate of 61.5%. Median overall survival (OS) from AZA start of the whole cohort was 13.5 months (95% CI, 8.2-18.7). There was no difference in median OS among patients with HI, PR, or CR (P = .908). These three subgroups as "responders" having been considered, a significantly better OS was observed in responder compared with nonresponder patients, with a median OS of 17.6 months (95% CI, 10.1-25.0) versus 4.1 months (95% CI, 0.4-10.0) (P = .001) Only female gender was significant for both achievement of response (.010) and OS duration (P = .002). In conclusion, AZA is useful for the management of MPN-AP/BP, with an overall response rate (HI + PR + CR) of 61.5% and a longer OS in responders.

[Appropriate use of trastuzumab in Lazio Region: therapeutic scenarios and estimation of possible savings for the Regional Health Service.] / Utilizzo appropriato del trastuzumab nel Lazio: scenari terapeutici e stima del possibile risparmio per il Servizio Sanitario Regionale.

BACKGROUND: The availability of subcutaneous (SC) and intravenous (EV) formulations of trastuzumab and the recent release of the biosimilar EV version (10/2018) increase the offer for the treatment of patients with breast or gastric cancer HER2 positive. In this context, it is necessary to build therapeutic scenarios form avalible data in order to estimate the potential savings for the Regional Health Service (RHS) taking into account the appropriateness of use and patient's preferences. AIM: To evaluate the available comparative evidence regarding the effectiveness and safety of the different trastuzumab formulations; to analyze the supply of trastuzumab by type of administration (EV/SC) in Lazio in 2018, identifying the most appropriate use; to hypothesize a cost-effective scenario for the Regional Health Service (SSR) in 2019. Mehods. With the working group formed by clinicians and methodologists, we analysed the evidence of efficacy and safety available to date for the different formulations of trastuzumab, also taking into account the recent availability of biosimilars and with particular regard to the phenomenon of the potential switch between different therapeutic options. In addition, for the year 2019 the available economic impact assessments were also simulated with data from the Lazio Region. Through the datas from direct pharmaceutical products, the transtuzumab cycles supplied in 2018 were identified separately for the available formulations (EV/SC). For each cycle of therapy, starting from the date of delivery, the possible presence of a concomitant treatment (± 2 days) was investigated, tracing the type and method of administration. The treatments (concomitant with trastuzumab) were identified for which there were conflicting modes of administration. In addition, the supply of SC per dispensing structure was evaluated and, on the basis of this information, a scenario of use was hypothesized that takes into account costs and plausible consumption. RESULTS: A review of the literature summarized the available evidence on the efficacy and safety of the use of trastuzumab in the recorded therapeutic indications. The review was discussed with the working group and used to reproduce, at regional level, the estimates of the economic impact of the different therapeutic choices possible with trastuzumab. As regards the data on the use of trastuzumab, in the Lazio Region in 2018, 22,214 treatment cycles were observed (at a cost of 33 million euro) for 2,407 patients; new users accounted for 52.2%. 46.8% of the cycles were administered via SC; the use of the biosimilar was observed from October onwards and involved 143 cycles (0.6%). In 68.4% of the cycles trastuzumab was administered in monotherapy; among the therapies associated with trastuzumab, the most frequent was pertuzumab (n=4,258, 19.2% of the total cycles), followed by paclitaxel (n=1,364, 6.1% of the total cycles). Among the cycles of trastuzumab in concomitant therapy (N=7,022), 17.3% was administered via SC despite the presence of other drugs administered via EV. The prescriptive pattern of trastuzumab was heterogeneous for the different delivery structures. The SC administration presents a variability in the supply from 26% to 70% (interquartile range) and does not seem to be related to the type and volume of activity of the hospital. If the biosimilar EV is expected to account for 55% of consumption by 2019, thus reducing the use of the EV originator to 10% and the SC originator to 35%, savings of more than €7 million. CONCLUSIONS: Through the use data of the different formulations available for trastuzumab and taking into account the prescriptive appropriateness (and patient preferences), it has been possible to identify a SSR scenario of economic convenience due to the greater use of the biosimilar.

Deferasirox in the treatment of iron overload during myeloproliferative neoplasms in fibrotic phase: does ferritin decrement matter?

Few data are available on the treatment with DFX in patients with transfusion dependent Ph- Myeloproliferative Neoplasms in fibrotic phase. Here we report 48MPNpatients and iron overload treated with DFX. Starting DFX dose was 20 mg/Kg in 23 patients, 15 mg/Kg in 20 patientsand 10 mg/Kg in 5 patients. After a median treatment of 27.6 months, 5 patients achieved ferritin<500 ng/ml, 11 < 1000 ng/ml and 3 a reduction >50% of basal ferritin with a global response rate of 41%. As to hematological improvement, 9/47 patients (19.1%) showed a persistent rise of Hb>1.5 g/dl, with disappearance of transfusion requirement in 6 cases. The median OS from DFX initiation in patients with chelation response was 61.0 months compared to 15.8 months in patients without chelation efficacy. Treatment with DFX is feasible and effective in MPN with iron overload and a hematological improvement can occur in a sizeable rate of patients.

Early mortality in myeloma patients treated with first-generation novel agents thalidomide, lenalidomide, bortezomib at diagnosis: A pooled analysis.

INTRODUCTION: Early toxic death (≤60 days of diagnosis) in elderly multiple myeloma (MM) patients is attributable to active disease, age and co-morbidities. Rate of early toxic deaths is 10% with conventional chemotherapy mainly due to infection and renal failure. Novel agents have improved MM outcome at the expense of newer toxicity. METHODS: We analyzed 1146 individual patient data to assess toxic deaths during induction treatment with first-generation novel agents thalidomide, lenalidomide, bortezomib. RESULTS: During first-line therapy, 119/1146 patients (10%) died for any cause, and 47/1146 (4%) due to toxicity, including 12/1146 (1%) early deaths. The 24-month cumulative incidence was 4.1% without any difference between bortezomib (18/503 patients, 4%) and lenalidomide (29/643patients, 5%; p = 0.31). Toxic deaths occurred in 34/1039 (3%) patients <80 years and 13/107 (12%) patients ≥80 years. Causes were cardiac events (28%), infections (26%) and vascular complications (15%). In a multivariate analysis, older age and unfavorable ISS stage increased the risk of death. CONCLUSION: First-generation novel agents significantly reduced toxic deaths compared to conventional chemotherapy. One third of deaths during first-line therapy were due to cumulative drug-related toxicities, thus supportive approaches and prevention strategies should be optimized. The higher mortality rate for toxicity in octogenarians confirms the need for a careful frailty assessment.

Cyclophosphamide's addition in relapsed/refractory multiple myeloma patients with biochemical progression during lenalidomide-dexamethasone treatment.

OBJECTIVE: The aim of this study was to evaluate the addition of cyclophosphamide in relapsed-refractory multiple myeloma patients (RRMM) who experienced biochemical relapse or progression without CRAB, during treatment with lenalidomide and dexamethasone (Rd), to slow down the progression in active relapse. METHODS: This analysis included 31 patients with RRMM treated with Rd who received cyclophosphamide (CRd) at biochemical relapse. The CRd regimen was continued until disease progression. RESULTS: The median number of CRd cycles administered was 8 (range: 1-35). A response was observed in 9 (29%) patients. After a median observation time of 11 months, the median overall survival (OS) from the beginning of CRd was 17.7 months. The median progression-free survival (PFS) from the beginning of CRd was 13.1 months. CONCLUSION: The addition of cyclophosphamide delays the progression in patients who present a biochemical relapse during Rd treatment. The response rate and the duration of PFS obtained with minimal toxicities and low costs induced us to setting up a randomized clinical trial.

Life for patients with myelofibrosis: the physical, emotional and financial impact, collected using narrative medicine-Results from the Italian 'Back to Life' project.

PURPOSE: Myelofibrosis (MF) is a chronic myeloproliferative neoplasm characterised by an aggressive clinical course, with disabling symptoms and reduced survival. Patients experience a severely impaired quality of life and their families face the upheaval of daily routines and high disease-related financial costs. The aim of this study was to investigate the perceptions of Italian patients and their caregivers about living with MF and the burden of illness associated with MF. METHODS: A quali-quantitative questionnaire and a prompted written narrative survey were administered to patients affected by primary or post-essential thrombocythemia/post-polycythaemia vera MF and their primary caregiver in 35 Italian haematological centres. RESULTS: In total, 287 questionnaires were returned by patients and 98 by caregivers, with 215 and 62, respectively, including the narrative. At the time of diagnosis, the most commonly expressed emotional states of patients were fear, distress and anger, confirming the difficulty of this phase. A high level of emotional distress was also reported by caregivers. Along the pathway of care, the ability to cope with the disease differed according to the quality of care received. The mean cost to each patient attributable to MF was estimated as €12,466 per year, with an estimated average annual cost of loss of income of €7774 per patient and €4692 per caregiver. CONCLUSIONS: Better understanding of the personal life of MF patients and their families could improve the relationships between health workers and patients, resulting in better focused healthcare pathways and more effective financial support to maintain patients in their social roles.

A Population-Based Study on Myelodysplastic Syndromes in the Lazio Region (Italy), Medical Miscoding and 11-Year Mortality Follow-Up: the Gruppo Romano-Laziale Mielodisplasie Experience of Retrospective Multicentric Registry.

Data on Myelodysplastic Syndromes (MDS) are difficult to collect by cancer registries because of the lack of reporting and the use of different classifications of the disease. In the Lazio Region, data from patients with a confirmed diagnosis of MDS, treated by a hematology center, have been collected since 2002 by the Gruppo Romano-Laziale Mielodisplasie (GROM-L) registry, the second MDS registry existing in Italy. This study aimed at evaluating MDS medical miscoding during hospitalizations, and patients' survival. For these purposes, we selected 644 MDS patients enrolled in the GROM-L registry. This cohort was linked with two regional health information systems: the Hospital Information System (HIS) and the Mortality Information System (MIS) in the 2002-2012 period. Of the 442 patients who were hospitalized at least once during the study period, 92% had up to 12 hospitalizations. 28.5% of patients had no hospitalization episodes scored like MDS, code 238.7 of the International Classification of Disease, Ninth Revision, Clinical Modification (ICD-9-CM). The rate of death during a median follow-up of 46 months (range 0.9-130) was 45.5%. Acute myeloid leukemia (AML) was the first cause of mortality, interestingly a relevant portion of deaths is due to cerebro-cardiovascular events and second tumors. This study highlights that MDS diagnosis and treatment, which require considerable healthcare resources, tend to be under-documented in the HIS archive. Thus we need to improve the HIS to better identify information on MDS hospitalizations and outcome. Moreover, we underline the importance of comorbidity in MDS patients' survival.
