Anthracycline treatment, cardiovascular risk factors and the cumulative incidence of cardiovascular disease in a cohort of newly diagnosed lymphoma patients from the modern treatment era.

The development of cardiovascular disease (CVD) in long-term survivors of lymphoma is of increasing importance. Here, we characterize the cumulative incidence and risk factors for CVD in lymphoma patients diagnosed in the current treatment era. From 2002-2015, newly diagnosed lymphoma patients (>18 years) were enrollment into a prospective cohort study that captured incident CVD, consisting of congestive heart failure (CHF), acute coronary syndrome (ACS), valvular heart disease (VHD), and arrhythmia. The cumulative incidence of CVD was calculated with death modeled as a competing risk. We estimated the association of treatment with anthracyclines or radiotherapy and traditional CVD risk factors with incidence of CVD using hazard ratios (HR) and 95% confidence intervals (CI) estimated from Cox regression. After excluding prevalent CVD at lymphoma diagnosis, the study consisted of 3063 patients with a median age of 59 years (range 18-95). The cumulative incidence of CVD at 10-years was 10.7% (95% CI, 9.5%-12.1%). In multivariable analysis, increasing age (HR = 1.05 per year, p < 0.001), male sex (HR = 1.36, p = 0.02), current smoker (HR = 2.10, p < 0.001), BMI > 30 kg/m2 (HR = 1.45, p = 0.01), and any anthracycline treatment (HR = 1.57, p < 0.001) were all significantly associated with risk of CVD. Anthracyclines were associated with increased risk of CHF (HR = 2.71, p < 0.001) and arrhythmia (HR = 1.61, p < 0.01), but not VHD (HR = 0.84, p = 0.58) or ACS (HR = 1.32, p = 0.24) after adjustment for CVD risk factors. Even in the modern treatment era, CVD remains common in lymphoma survivors and preventive efforts are required that address both treatment and CVD risk factors.

Atypical Chronic Myeloid Leukemia: New Developments from Molecular Diagnosis to Treatment.

Atypical Chronic Myeloid Leukemia, BCR-ABL1 negative (aCML) is a rare hematological entity, included in the group of myelodysplastic (MDS)/myeloproliferative (MPN) overlap syndromes. It is characterized by an aggressive course, a high rate of acute myeloid leukemia (AML) transformation, and a dismal outcome. The clinical presentation includes splenomegaly and leukocytosis with neutrophilia and left-shifted granulocytosis accompanied by granulocytic dysplasia and sometimes multilineage dysplasia. In past years, the disease incidence was likely underestimated, as diagnosis was only based on morphological features. Recently, the improving knowledge in the molecular biology of MDS/MPN neoplasms has made it possible to distinguish aCML from other overlapping syndromes, basing on next generation sequencing. Among the most commonly mutated genes, several involve the Jak-STAT, MAPK, and ROCK signaling pathways, which could be actionable with targeted therapies that are already used in clinical practice, opening the way to tailored treatment in aCML. However, currently, there are few data available for small samples, and allogeneic transplant remains the only curative option for eligible patients.

Role of systemic high-dose methotrexate and combined approaches in the management of vitreoretinal lymphoma: A single center experience 1990-2018.

Vitreoretinal lymphoma (VRL) management remains a challenge. We present 72 patients with VRL, diagnosed at Mayo Clinic between 1990-2018. Three nondiffuse large B-cell lymphoma (DLBCL) histology cases were excluded. Among 69 DLBCL, 33 patients had primary VRL (PVRL), 18 concurrent intraocular and central nervous system (CNS) or systemic disease and 18 secondary VRL. Patients received intraocular chemotherapy (intraocular injections of rituximab or metothrexate or steroids or in combination), radiotherapy, systemic or combined systemic plus intraocular treatment in 9, 10, 35, and 15 cases, respectively. Among primary and concurrent VRL, median failure free survival (FFS), CNS relapse-free survival (CNS-RFS) and overall survival (OS) were: 1.8, 4.9, and 4.1 years, respectively; among PVRL, median FFS, CNS-RFS, and OS were: 2.6 year, Not Reached and 9.3 year, respectively. No CNS relapse occurred beyond 4 years in PVRL. Median OS for patients diagnosed between 1990 and 1999 vs between 2000 and 2018 was 1.5 vs 9.4 years, respectively (P = .0002). OS was significantly higher in PVRL, as compared with concurrent VRL (P = .04). Previous immunosuppression and poor performance status were predictive of worse outcome. In PVRL, a combined systemic and intraocular therapy showed higher FFS (P = .002) and CNS-RFS (P = .003), but no differences in OS. Among 18 secondary VRL, at a median follow-up of 1.1 year after vitreoretinal relapse, median FFS and OS were 0.3 and 1.3 years. An improvement in survival of VRL has been observed over the decades. PVRL should undergo combined systemic and intraocular chemotherapy to prevent CNS progression.

Lenalidomide in Pretreated Mantle Cell Lymphoma Patients: An Italian Observational Multicenter Retrospective Study in Daily Clinical Practice (the Lenamant Study).

BACKGROUND: Mantle cell lymphoma (MCL) has the worst prognosis of B-cell subtypes owing to its aggressive clinical disease course and incurability with standard chemo-immunotherapy. Options for relapsed MCL are limited, although several single agents have been studied. Lenalidomide is available in Italy for patients with MCL based on a local disposition of the Italian Drug Agency. SUBJECTS, MATERIALS, AND METHODS: An observational retrospective study was conducted in 24 Italian hematology centers with the aim to improve information on effectiveness and safety of lenalidomide use in real practice. RESULTS: Seventy patients received lenalidomide for 21/28 days with a median of eight cycles. At the end of therapy, there were 22 complete responses (31.4%), 11 partial responses, 6 stable diseases, and 31 progressions, with an overall response rate of 47.1%. Eighteen patients (22.9%) received lenalidomide in combination with either dexamethasone (n = 13) or rituximab (n = 5). Median overall survival (OS) was reached at 33 months and median disease-free survival (DFS) at 20 months: 14/22 patients are in continuous complete response with a median of 26 months. Patients who received lenalidomide alone were compared with patients who received lenalidomide in combination: OS and DFS did not differ. Progression-free survivals are significantly different: at 56 months, 36% in the combination group versus 13% in patients who received lenalidomide alone. Toxicities were manageable, even if 17 of them led to an early drug discontinuation. CONCLUSION: Lenalidomide therapy for relapsed MCL patients is effective and tolerable even in a real-life context. IMPLICATION FOR PRACTICE: Several factors influence treatment choice in relapsed/refractory mantle cell lymphoma (rrMCL), and the therapeutic scenario is continuously evolving. In fact, rrMCL became the first lymphoma for which four novel agents have been approved: temsirolimus, lenalidomide, ibrutinib, and bortezomib. The rrMCL therapeutic algorithm is not so well established because data in the everyday clinical practice are still poor. Lenalidomide for rrMCL patients is effective and tolerable even in a real-life context.

Yttrium-90 ibritumomab tiuxetan (Zevalin) followed by BEAM (Z-BEAM) conditioning regimen and autologous stem cell transplantation (ASCT) in relapsed or refractory high-risk B-cell non-Hodgkin lymphoma (NHL): a single institution Italian experience.

Chemo-refractory NHL has a very poor outcome; the addiction of RIT to salvage regiment pre ASCT had recently demonstrated promising results.We performed a retrospective sequential study to determine the feasibility of standard Zevalin with BEAM in high-risk relapse/refractory NHL. A matched cohort analysis with a group treated with standard BEAM without Zevalin was performed as secondary endpoint. Between October 2006 and January 2013, 37 NHL patients at high risk for progression or early (< 1 year) or multiple relapses were treated with Z-BEAM and ASCT after R-DHAP or R-ICE as salvage therapy. Clinical characteristics were 19 refractory and 18 early or multiple relapse; 16 patients received 1, and 21 had 2 or more previous rituximab-containing chemotherapy. At the end of treatment, response was CR 22 (59%), PR 10 (27%), PD 4 (11%), and toxic death (TD) 1 (3%). With a median follow up of 61 months, 3-year PFS was 61% and OS 61%. Fifteen patients died, 12 of lymphoma. Comparison with 21 treated with BEAM alone showed a numerical higher 3-yr PFS rate in favor of Z-BEAM but not statistically significant (57 vs 48%). With the limitation of the small sample subgroup analysis, a significant benefit was observed in relapsed patients for PFS (78% Z-BEAM vs 22% BEAM p = 0.016) and OS (83% Z-BEAM vs 22% BEAM p = 0.001). In relapsed/refractory high-risk NHL, Z-BEAM+ASCT is able to achieve a good ORR. Three-year PFS is promising for early relapsed patients but is not satisfactory for those with refractory disease.

Rituximab-dose-dense chemotherapy with or without high-dose chemotherapy plus autologous stem-cell transplantation in high-risk diffuse large B-cell lymphoma (DLCL04): final results of a multicentre, open-label, randomised, controlled, phase 3 study.

BACKGROUND: The prognosis of young patients with diffuse large B-cell lymphoma at high risk (age-adjusted International Prognostic Index [aa-IPI] score 2 or 3) treated with R-CHOP (rituximab, cyclophosphamide, vincristine, doxorubicin, and prednisone) is poor. The aim of this study was to investigate the possible benefit of intensification with high-dose chemotherapy and autologous stem-cell transplantation as part of first-line treatment in these patients. METHODS: We did a multicentre, open-label, randomised, controlled, phase 3 trial with a 2 × 2 factorial design to compare, at two different R-CHOP dose levels, a full course of rituximab-dose-dense chemotherapy (no transplantation group) versus an abbreviated course of rituximab-dose-dense chemotherapy followed by consolidation with R-MAD (rituximab plus high-dose cytarabine plus mitoxantrone plus dexamethasone) and high-dose BEAM chemotherapy (carmustine, etoposide, cytarabine, and melphalan) plus autologous stem-cell transplantation (transplantation group) in young patients (18-65 years) with untreated high-risk diffuse large B-cell lymphoma (aa-IPI score 2-3). At enrolment, patients were stratified according to aa-IPI score and randomly assigned (1:1:1:1) to receive R-CHOP (intravenous rituximab 375 mg/m2, cyclophosphamide 750 mg/m2, doxorubicin 50 mg/m2, and vincristine 1·4 mg/m2 on day 1, plus oral prednisone 100 mg on days 1-5) delivered in a 14-day cycle (R-CHOP-14) for eight cycles; high-dose R-CHOP-14 (R-MegaCHOP-14; R-CHOP-14 except for cyclophosphamide 1200 mg/m2 and doxorubicin 70 mg/m2) for six cycles; R-CHOP-14 for four cycles followed by R-MAD (intravenous rituximab 375 mg/m2 on day 1 or 4 plus intravenous cytarabine 2000 mg/m2 and dexamethasone 4 mg/m2 every 12 h on days 1-3 plus intravenous mitoxantrone 8 mg/m2 on days 1-3) plus BEAM (intravenous carmustine 300 mg/m2 on day -7, intravenous cytarabine 200 mg/m2 twice a day on days -6 to -3, intravenous etoposide 100 mg/m2 twice a day on days -6 to -3, plus intravenous melphalan 140 mg/m2 on day -2) and autologous stem-cell transplantation (day 0); or R-MegaCHOP-14 for four cycles followed by R-MAD plus BEAM and autologous stem-cell transplantation. The primary endpoint was failure-free survival at 2 years in the intention-to-treat population. This study is registered with EudraCT (2005-002181-14; 2007-000275-42) and with ClinicalTrials.gov, number NCT00499018. FINDINGS: Between Jan 10, 2006, and Sept 8, 2010, 399 patients were randomly assigned to receive transplantation (n=199) or no transplantation (n=200); 203 patients were assigned to receive R-CHOP-14 and 196 were assigned to receive R-MegaCHOP-14. With a median follow-up of 72 months (IQR 57-88), 2-year failure-free survival was 71% (95% CI 64-77) in the transplantation group versus 62% (95% CI 55-68) in the no transplantation group (hazard ratio [HR] 0·65 [95% CI 0·47-0·91]; stratified log-rank test p=0·012). No difference in 5-year overall survival was observed between these groups (78% [95% CI 71-83] versus 77% [71-83]; HR 0·98 [0·65-1·48]; stratified log-rank test p=0·91). Grade 3 or worse haematological adverse events were reported in 183 (92%) of 199 patients in the transplantation group versus 135 (68%) of 200 patients in the no transplantation group. Grade 3 or worse non-haematological adverse events were reported in 90 (45%) versus 31 (16%); the most common grade 3 or worse non-haematological adverse event was gastrointestinal (49 [25%] vs 19 [10%]). Treatment-related deaths occurred in 13 (3%) patients; eight in the transplantation group and five in the no transplantation group. INTERPRETATION: Abbreviated rituximab-dose-dense chemotherapy plus R-MAD plus BEAM and autologous stem-cell transplantation reduced the risk of treatment failure compared with full course rituximab-dose-dense chemotherapy in young patients with diffuse large B-cell lymphoma at high risk. However, these results might not be clinically meaningful, since this improvement did not reflect an improvement in overall survival. These results do not support further consideration of the use of intensification of R-CHOP as an upfront strategy in patients with diffuse large B-cell lymphoma with poor prognosis.

Lenalidomide plus R-CHOP21 in elderly patients with untreated diffuse large B-cell lymphoma: results of the REAL07 open-label, multicentre, phase 2 trial.

BACKGROUND: Up to 40% of elderly patients with untreated diffuse large B-cell lymphoma (DLBCL) given a regimen of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone every 21 days (R-CHOP21) relapse or develop refractory disease. Lenalidomide has high activity in relapsed or refractory aggressive B-cell lymphomas. In phase 2 of the REAL07 trial, we aimed to establish the safety and efficacy of the combination of lenalidomide and R-CHOP21 in elderly patients with untreated DLBCL. METHODS: REAL07 was an open-label, multicentre trial that was done in 13 centres in Italy and one in Germany. Eligible patients were aged 60-80 years; had newly diagnosed, untreated, CD20-positive, Ann Arbor stage II-IV DLBCL or grade 3b follicular lymphoma; had an Eastern Cooperative Oncology Group performance status of 0-2; had an International Prognostic Index (IPI) risk of low-intermediate, intermediate-high, or high; and were fit according to comprehensive geriatric assessment. Participants were to receive 15 mg oral lenalidomide on days 1-14 of six 21-day cycles, and standard doses of R-CHOP21 chemotherapy (375 mg/m(2) intravenous rituximab, 750 mg/m(2) intravenous cyclophosphamide, 50 mg/m(2) intravenous doxorubicin, and 1·4 mg/m(2) intravenous vincristine on day 1, and 40 mg/m(2) oral prednisone on days 1-5). The primary endpoint was frequency of overall response (complete response [CR] and partial response [PR]), which was assessed by (18)F-fluorodeoxyglucose ((18)F-FDG) PET at the end of the treatment. Analyses were by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00907348. FINDINGS: 49 patients were included in phase 2: nine had been enrolled into phase 1 between Oct 23, 2008, and June 4, 2009, and had received the maximum tolerated dose of 15 mg lenalidomide; and 40 were enrolled into phase 2 between April 28, 2010, and June 3, 2011. 45 patients (92%, 95% CI 81-97) achieved a response (42 [86%] CR; three [6%] PR). Three patients (6%) did not respond and one (2%) died for reasons unrelated to treatment or disease. 277 (94%) of 294 planned cycles of lenalidomide and R-CHOP21 were completed. Grade 3-4 neutropenia was reported in 87 cycles (31%), grade 3-4 leukopenia in 77 (28%), and grade 3-4 thrombocytopenia in 35 (13%). No grade 4 non-haematological adverse events were reported. No patients died during the study as a result of toxic effects. INTERPRETATION: Lenalidomide with R-CHOP21 is effective and safe in elderly patients with untreated DLBCL.

Lymphoma: The Added Value of Radiomics, Volumes and Global Disease Assessment.

Lymphoma represents a condition that holds promise for cure with existing treatment modalities; nonetheless, the primary clinical obstacle lies in advancing therapeutic outcomes by pinpointing high-risk individuals who are unlikely to respond favorably to standard therapy. In this article, the authors will delineate the significant strides achieved in the lymphoma field, with a particular emphasis on the 3 prevalent subtypes: Hodgkin lymphoma, diffuse large B-cell lymphomas, and follicular lymphoma.

Fertility preservation in lymphoma patients treated with immunochemotherapy regimens with or without radiotherapy: results of a retrospective multicenter Italian study (Ferty care).

This is a retrospective, multicentric study, aimed to describe the real-life application of fertility preservation methods during treatment in female lymphoma patients, aged 18-40 years old, diagnosed between Oct 1st/2010 and May 31st/2018. Among 414 women included, median age was 28 years old, histologies were: HL 74%, PMBCL 13%, DLBCL 10%, others 3%. First line treatments were: ABVD in 295 (71%), R-CHOP like in 102 (25%), higher intensity regimens in 17 (4%) cases. Fertility preservation strategies were: GnRHa in 315 (78%), Oral Contraceptive in 41 (10%), oocytes and ovarian tissue cryopreservation in 55 and 42 patients, respectively. After therapy, we observed a restored regular period in 293 (70%) and premature ovarian failure (POF) in 33 (8%), Furthermore we recorded 43 pregnancies, all spontaneous with 5 years median follow-up. Median age at diagnosis and number of lines of treatment correlate with higher rate of amenorrhea, risk of POF and menopause (p < 0.001).

Lenalidomide plus cyclophosphamide, doxorubicin, vincristine, prednisone and rituximab is safe and effective in untreated, elderly patients with diffuse large B-cell lymphoma: a phase I study by the Fondazione Italiana Linfomi.

Despite improvements in standard therapy with rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone for patients with untreated, diffuse large B-cell lymphoma, up to 40% of these patients relapse. Lenalidomide alone or in combination with rituximab has been shown to be active in relapsed/refractory aggressive lymphomas. In this phase I study we determined the maximum tolerated dose of lenalidomide plus rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone in untreated, elderly (median age 68 years) patients with diffuse large B-cell lymphoma. Four lenalidomide doses (5, 10, 15, and 20 mg/day on days 1-14) allocated using the continual reassessment method were planned to be administered for 14 days in combination with each course of rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone for a total of six courses. Seven cohorts of patients (n=3 in each cohort) were treated (total n=21) at 10, 20, 15, 15, 15, 10, and 10 mg of lenalidomide. Dose-limiting toxicities occurred in seven patients during the first three courses of treatment. The third dose-level of lenalidomide (15 mg/day) was selected as the maximum tolerated dose, with an estimated probability of dose-limiting toxicities of 0.345 (95% credibility interval 0.164-0.553). Grade 3-4 hematologic adverse events were: neutropenia in 28% of the courses, thrombocytopenia in 9%, and anemia in 3%. Non-hematologic toxicities were moderate: grade 4 increase of creatinine phosphokinase (n=1), grade 3 cardiac (n=2), grade 3 neurological (n=3), and grade 3 gastrointestinal (n=1). In this phase I study, the overall response rate was 90%, with 81% achieving complete remission. This combination regimen appears safe in elderly patients with diffuse large B-cell lymphoma and its efficacy will be assessed in the ongoing phase II trial. This trial was registered at www.clinicaltrials.gov as NCT00907348.

Comparison of first-line treatment with bendamustine plus rituximab versus R-CHOP for patients with follicular lymphoma grade 3A: Results of a retrospective study from the Fondazione Italiana Linfomi.

In the setting of follicular lymphoma (FL), frontline therapy with rituximab, cyclophosphamide, doxorubicin, and prednisone (R-CHOP) has represented for many years the standard of care for patients with symptomatic advanced disease. More recently, the combination of bendamustine plus rituximab (R-B) has emerged as an alternative therapeutic option. We present a retrospective, multicenter, observational study aimed at comparing outcomes and toxicities observed in 145 patients diagnosed with grade 3A FL treated with a first line therapy in 15 Italian Fondazione Italiana Linfomi centers between the 1st of January 2014 and the 30th of May 2018. Seventy patients were treated with R-B and 75 with R-CHOP. In the R-B group, the median age at the time of diagnosis was 67 years compared with 59 years in the R-CHOP group. Patients in R-B group achieved a similar overall response rate (96% vs. 99%) and a better complete remission rate (87% vs. 80%, p=0.035) compared with patients in R-CHOP group. Progression free survival (PFS) was similar between individual treated with R-CHOP and R-B (48- month PFS 77.7% vs. 76.6% respectively, p=0.745). The overall survival was significantly longer with R-CHOP treatment (HR=0.16; 95% IC, 0.04-0.74; p=0.007); however, no statistical significant difference was observed after adjustment for age. With the limitations of the study design, our results suggest that both R-B and R-CHOP seem to be valid first-line treatment options in FL3A.

Changing Trends in B-Cell Non-Hodgkin Lymphoma Treatment: The Role of Novel Monoclonal Antibodies in Clinical Practice.

We are currently witnessing a dramatic shift in our approach to the treatment of B-cell non-Hodgkin lymphoma (B-NHL). In the evolving clinical landscape, novel treatments for this clinically heterogeneous disease span a wide range of interventions, encompassing targeted agents, cell therapy approaches, and novel monoclonal antibodies (NMABs). Among these, the latter are likely to exert the most profound impact due to their distinctive high efficacy and versatile applicability. NMABs represent a heterogeneous group of agents, including naked antibodies, immunotoxins, and T-cell-engaging molecules. In recent times, several NMABs have either gained regulatory approval or are on the verge of introduction into clinical practice, addressing multiple therapeutic indications and treatment regimens. Their anticipated impact is expected to be broad, initially in the context of relapsed/refractory (R/R) disease and subsequently extending to early treatment lines. The scope of this review is to provide a comprehensive overview of the biological characteristics, clinical properties, efficacy, and toxicity profiles of NMABs that have recently been introduced or are nearing integration into clinical practice.

Italian Real-Life Experience on the Use of Mogamulizumab in Patients with Cutaneous T-Cell Lymphomas.

Mycosis fungoides and Sèzary syndrome are the most studied subtypes common cutaneous T-cell lymphomas. The current treatment objective is to improve the clinical manifestations of the disease in the affected areas, to relieve symptoms and to halt disease progression. Patients with early-stage mycosis fungoides are usually managed with skin-directed therapies, whereas patients with resistant or advanced-stage mycosis fungoides or Sèzary syndrome often require systemic drugs. Over the last decade, new drugs have been developed, increasing the breadth of treatment options for cutaneous T-cell lymphomas patients. Mogamulizumab is a first-in-class defucosylated humanized IgG1 κ monoclonal antibody, which exerts its anti-tumour action by selectively binding to C-C chemokine receptor 4 and increasing antibody-dependent cellular cytotoxicity activity against malignant T-cells. Several clinical trials showed that mogamulizumab is able to effectively control the cutaneous T-cell lymphomas in each site (skin, blood, lymph nodes and viscera), improving patients' symptoms, function and overall quality of life with a manageable safety profile. In this report, we discuss 12 cases of patients with mycosis fungoides or Sèzary syndrome successfully treated with mogamulizumab in real-life clinical practice in Italy.

Evolving frontline immunochemotherapy for mantle cell lymphoma and the impact on survival outcomes.

Because there have been a dvances in frontline treatment for mantle cell lymphoma (MCL) over the last 2 decades, we sought to characterize the changes in frontline treatment patterns and their association with outcomes. Patients with newly diagnosed MCL from September 2002 through June 2015 were enrolled in a prospective cohort study, and clinical characteristics, treatment, and clinical outcomes were compared between patients diagnosed from 2002 to 2009 (Era 1) compared with 2010 to 2015 (Era 2). Patient age, sex, and simplified MCL International Prognostic Index (sMIPI) score were similar between the 2 groups. In patients age 65 years or younger, there was less use of rituximab plus hyperfractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone (R-Hyper-CVAD) (16.1% vs 8.8%) but more use of rituximab plus maximum-strength cyclophosphamide, doxorubicin, vincristine, and prednisone (R-maxi-CHOP) alternating with rituximab plus high-dose cytarabine (R-HiDAC), also known as the Nordic regimen, and R-CHOP alternating with rituximab plus dexamethasone, high-dose cytarabine, and cisplatin (R-DHAP) (1.1% vs 26.4%) and less use of R-CHOP or R-CHOP-like regimens (64.5% vs 35.2%) but more use of R-bendamustine (0% vs 12.1%) in Era 2 (P < .001). These changes were associated with improved event-free survival (EFS; 5-year EFS, 34.3% vs 50.0%; P = .010) and overall survival (OS; 5-year OS, 68.8% vs 81.6%; P = .017) in Era 2. In patients older than age 65 years, there was less use of R-CHOP or R-CHOP-like therapy (39.0% vs 14.3%) and nonstandard systemic therapy (36.6% vs 13.0%) but more use of R-bendamustine (0% vs 49.4%). These changes were associated with a trend for improved EFS (5-year EFS, 25.4% vs 37.5%; P = .051) in Era 2. The shift from R-CHOP or R-CHOP-like regimens to R-bendamustine was associated with improved EFS (5-year EFS, 25.0% vs 44.6%; P = .008) in Era 2. Results from this prospective cohort study provide critical real-world evidence for improved outcomes with evolving frontline patterns of care in patients with MCL.

Clinical characteristics and outcomes of primary versus secondary gastrointestinal mantle cell lymphoma.

Primary gastrointestinal (GI) mantle cell lymphoma (MCL) is rare and the optimal management is unknown. We reviewed 800 newly diagnosed MCL cases and found 22 primary (2.8%) and 79 (9.9%) secondary GI MCL cases. Age, sex, and performance status were similar between primary and secondary cases. Secondary cases had more elevations in lactate dehydrogenase (28% vs 0%, P = 0.03) and a trend for a higher MCL international prognostic index (P = 0.07). Observation or local therapy was more common for primary GI MCL (29% vs 8%, P < 0.01), and autologous stem-cell transplant was more common for secondary GI MCL (35% vs 14%, P < 0.05). The median follow-up was 85 months. Primary and secondary GI MCL had similar 5-year progression-free survival (PFS) (30% vs 28%, P = 0.59) and overall survival (OS) (65% vs 66%, P = 0.83). The extent of GI involvement in primary GI MCL affected treatment selection but not outcome, with a 5-year PFS of 43% vs 14% vs 31% (P = 0.48) and OS of 57% vs 71% vs 69% (P = 0.54) in cases with single lesion vs multiple lesions in 1 organ vs multiple lesions in ≥2 organs. Less aggressive frontline treatment for primary GI MCL is reasonable. It is unknown whether more aggressive treatment can result in improved outcomes.

Diagnosis of maternal Hodgkin lymphoma following abnormal findings at noninvasive prenatal screening test (NIPT): Report of two cases.

Abnormal NIPT results, contrasting with normal fetus development, could disclose maternal malignancy, and this possibility should always be explained during pretest counseling. In this case, a complete diagnostic assessment is recommended and should be managed by a multidisciplinary team to define the best timing for diagnostic procedures, delivery, and treatment.

The Role of Monoclonal Antibodies in the First-Line Treatment of Transplant-Ineligible Patients with Newly Diagnosed Multiple Myeloma.

Elderly transplant-ineligible (NTE) patients represent the majority of patients affected by multiple myeloma (MM). Elderly patients are a highly heterogeneous population, with large variability in health and functional status. Thus, choosing their optimal treatment is challenging. A wide range of first-line treatments is available, and novel-agent combinations, including monoclonal antibodies (mAbs), have recently entered clinical practice. The combination of the anti-CD38 mAb daratumumab with bortezomib, melphalan and prednisone (Dara-VMP) or lenalidomide and dexamethasone (Dara-Rd) demonstrated impressive advantages in terms of progression-free survival and minimal residual disease negativity, as compared to VMP and Rd, without safety concerns. Another anti-CD38 mAb, isatuximab, is showing encouraging results, and new isatuximab-based combinations might enter clinical practice in the future. Nevertheless, available data come from clinical trials with selected patient populations and, to date, the manageability of these regimens in real-life patients or in frail patients remains unknown. Frailty-tailored treatments, including mAbs, are under evaluation in preliminary studies. In this review, we analyze recently approved mAb-based treatments for NTE newly diagnosed MM patients and new combinations under evaluation, focusing on the efficacy and safety of these regimens and on open issues regarding the choice of therapy for elderly patients.

Immunoglobulin M (IgM) multiple myeloma versus Waldenström macroglobulinemia: diagnostic challenges and therapeutic options: two case reports.

BACKGROUND: Immunoglobulin M multiple myeloma and Waldenström macroglobulinemia are two different hematological diseases with the common finding of an immunoglobulin M monoclonal gammopathy of unknown significance. However, clinical characteristics of the two entities can overlap. CASE PRESENTATION: In this report, we describe two cases of immunoglobulin M neoplasm with the same histological bone marrow presentation but with different clinical behavior, cytogenetics, and biological assessment. On the basis of comprehensive diagnostic workup, these patients were considered to have different diseases and treated accordingly with different approaches. Patient 1 (Caucasian man) presented with increased serum protein and immunoglobulin M (7665 mg/L) with an M-spike electrophoresis of 4600 mg/L. His bone marrow biopsy revealed a small-cell immunoglobulin M multiple myeloma. The result of testing for the MYD88 L265P mutation was negative, while fluorescence in situ hybridization analysis showed translocation t(11,14). A diagnosis of immunoglobulin M-κ multiple myeloma was made. Patient 1 was a candidate for bortezomib plus thalidomide and dexamethasone, followed by autologous stem cell transplant consolidation. Patient 2 (Caucasian man) showed an M-spike by protein electrophoresis (300 mg/L, 4.9%), with serum immunoglobulin M level of 327 mg/L. His bone marrow biopsy revealed immunoglobulin M-κ multiple myeloma. Computed tomography showed many enlarged lymph nodes and splenomegaly. Patient 2's clinical features were suggestive of Waldenström macroglobulinemia, in contrast to the bone marrow biopsy results. The result of testing for the MYD88 L265P mutation was positive. Patient 2 was diagnosed with Waldenström macroglobulinemia and received rituximab, cyclophosphamide, and dexamethasone. CONCLUSIONS: A correct differential diagnosis between immunoglobulin M multiple myeloma and Waldenström macroglobulinemia is a critical point in the setting of a new immunoglobulin M monoclonal gammopathy onset. These patients should undergo a complete diagnostic workup with pathological, radiological, and serological examinations to establish the diagnosis and plan the most appropriate treatment in order to improve the prognosis.

Aggressive Non-Hodgkin lymphomas: risk factors and treatment of central nervous system recurrence.

Introduction: Secondary central nervous system lymphoma (SCNSL) is a potentially fatal event in the setting of aggressive Non-Hodgkin Lymphomas. Nowadays, despite of the very poor outcome of SCNSL, several studies are going to identify the high-risk patients' subgroup that could early develop this detrimental event and in whom the central nervous system (CNS) prophylaxis could improve survival. Areas covered: Herein, the authors will review the prophylactic and treatment strategy for SCNSL, focusing on the identification of high-risk subgroup. Expert opinion: The validated CNS International Prognostic Index score lacks sensitivity. The role of prophylaxis has been suggested as an important step for selected patients. Intrathecal prophylaxis is always less consolidated, due to its doubtful efficacy, whereas systemic high-dose methotrexate is becoming the favored option to reduce CNS relapse in high-risk aggressive lymphomas. However, there is no a clear guideline to help physicians in clinical practice. The encouraging results on treatment of primary CNS lymphoma prompted new therapeutic strategies for SCNSL, although larger and randomized prospective studies are needed. Future efforts should be addressed to better clarify these open questions.
