Purpose: To evaluate the reliability of the Deauville score (DS) in therapy response assessment and to define the prognostic value of the metabolic response of end of induction (EOI) [ 18 F]FDG PET (PET) in follicular lymphoma patients., Methods: Adult patients with untreated grade 1-3a FL/ stage II-IV enrolled in the multicentre, prospective, phase III FOLL12 trial (NCT02063685) were randomized to receive standard immunochemotherapy followed by rituximab maintenance (standard arm) versus standard immunochemotherapy followed by response-adapted post-induction management (experimental arm). Baseline and EOI PET were mandatory for the study. All PET scans were centralized on the WIDEN® platform and classified according to DS in a blind independent central review. DS1-3 was considered negative (CMR), whereas DS4-5 was considered positive (not CMR). The primary endpoint was PFS. The main secondary endpoint was overall survival (OS)., Results: Overall, 807 follicular lymphoma patients-52% women, 89% stage III-IV disease, 40% with a high-risk FLIPI-2 score (3-5)-were enrolled in the study; 729 (90.4%) baseline and EOI PET were available for the analysis. EOI PET was positive (DS4-5) in 88/729 (12.1%) cases. Overall inter-reviewer agreement on PET pos/neg result was 0.92, while agreement on positive and negative cases was 0.77 and 0.94, respectively. The median follow-up was 69 months; 247 events were registered in the 5-yr follow-up, with a 5-yr PFS of 67% (95%CI: 63%-70%). The 5-yr PFS rate for PET neg (DS1-3) and PET pos (DS4-5) patients was 71% (95%CI: 67%-75%) and 36% (95%CI: 25%-46%), respectively, with HR 3.49 (95%CI: 2.57-4.72). Five-year PFS was worse as DS increased, with 74% (70%-78%), 58% (48%-67%; HR 1.71; p = 0.001)] and 36% (25%-46%; HR 3.88; p < 0.001) in DS1-2, DS3 and DS4-5, respectively. EOI PET maintained its prognostic value in both the standard and experimental arms. In the whole population, 5-yr OS was 94% (95%CI: 92%-96%), with 96% (95%CI: 94-97) and 82% (95%CI: 72%-89%) in EOI PET negative (DS1-3) and positive (DS4-5), respectively (HR 4.48; p < 0.001). When DS was associated with FLIPI-2, patients with DS3 or DS1-2 with high FLIPI-2 (3-5) experienced worse OS than patients with DS1-2 and low FLIPI-2 (1-2) (p = 0.003)., Conclusion: This study shows that DS is a reliable prognostic tool to evaluate EOI PET in follicular lymphoma patients, with prognostic value maintained both in the standard and experimental arms, making metabolic imaging a robust tool to assess response in FL. Moreover, although preliminary, this study provides further information on DS3 patients, who are considered as CMR but show a less favourable PFS than DS1-2 patients., (© 2024.

The IELSG38 trial was conducted to investigate the effects of subcutaneous (SC) rituximab on the complete remission (CR) rate and the benefits of SC rituximab maintenance in patients with extranodal marginal zone lymphoma (MZL) who received front-line treatment with chlorambucil plus rituximab. Study treatment was an induction phase with oral chlorambucil 6 mg/m2/day on weeks 1-6, 9-10, 13-14, 17-18, and 21-22, and intravenous rituximab 375 mg/m2 on day 1 of weeks 1-4, and 1,400 mg SC on weeks 9, 13, 17, and 21. Then, a maintenance phase followed with rituximab administered at 1,400 mg SC every two months for two years. Of the 112 patients enrolled, 109 were evaluated for efficacy. The CR rates increased from 52% at the end of the induction phase to 70% upon completion of the maintenance phase. With a median follow-up of 5.8 years, the 5-year event-free, progression-free, and overall survival rates were 87% (95% CI: 78-92), 84% (95% CI: 75-89), and 93% (95% CI: 86-96), respectively. The most common grade ≥3 toxicities were neutropenia (33%) and lymphocytopenia (16%). Six patients experienced treatment-related serious adverse events, including fever of unknown origin, sepsis, pneumonia, respiratory failure, severe cerebellar ataxia, and fatal acute myeloid leukemia. The trial showed that SC rituximab did not improve the CR rate at the conclusion of the induction phase, which was the main endpoint. Nevertheless, SC rituximab maintenance might have facilitated long-term disease control, potentially contributing to enhanced event-free and progression-free survival.

Peripheral T-cell lymphomas (PTCLs) are a heterogeneous group of haematological cancers with generally poor clinical outcomes. However, a subset of patients experience durable disease control, and little is known regarding long-term outcomes. The International T-cell Lymphoma Project (ITCLP) is the largest prospectively collected cohort of patients with PTCLs, providing insight into clinical outcomes at academic medical centres globally. We performed a long-term outcome analysis on patients from the ITCLP with available 10-year follow-up data (n = 735). The overall response rate to first-line therapy was 68%, while 5- and 10-year overall survival estimates were 49% and 40% respectively. Most deaths occurred prior to 5 years, and for patients alive at 5 years, the chance of surviving to 10 years was 84%. However, lymphoma remained the leading cause of death in the 5- to 10-year period (67%). Low-risk International Prognostic Index and Prognostic Index for T-cell lymphoma scores both identified patients with improved survival, while in multivariate analysis, age >60 years and Eastern Cooperative Oncology Group performance status 2-4 were associated with inferior outcomes. The favourable survival seen in patients achieving durable initial disease control emphasizes the unmet need for optimal front-line therapeutic approaches in PTCLs., (© 2024 British Society for Haematology and John Wiley & Sons Ltd.)

Lymphoma patients are at high risk of cardiovascular events due to anthracycline cardiotoxicity and, in rare cases, related to heart infiltration. The presence of cardiac masses adds further complexity to the management of lymphoma patients beyond myocardial chemotherapy-related toxicity, given possible unpredictable acute complications such as arrhythmias, atrioventricular block, myocardial ischemia, pericardial effusion and cardiac tamponade. Here we describe the clinical presentation and successful multidisciplinary management of diffuse large B-cell lymphoma with multifocal cardiac involvement identified by total body 18FDG positron emission tomography performed at disease staging.

Background: The mainstay of treatment for early-stage follicular lymphoma is local radiotherapy, with a possible role for anti-CD20 monoclonal antibody (mAb). We aimed to evaluate the effect of these treatments using a measurable residual disease (MRD)-driven approach., Methods: This prospective, multicentre, phase 2 trial was conducted at 27 centres of the Fondazione Italiana Linfomi (FIL) in Italy. Eligible participants were adults (≥18 years) with newly diagnosed, histologically confirmed follicular lymphoma (stage I or II; grade I-IIIa). Patients were initially treated with 24 Gy involved-field radiotherapy over 12 days; those who were MRD-positive after radiotherapy or during follow-up received eight intravenous doses (1000 mg per dose; one dose per week) of the anti-CD20 mAb ofatumumab. The primary endpoint was the proportion of patients who were MRD-positive after involved-field radiotherapy and became MRD-negative after ofatumumab treatment. Patients were included in the primary endpoint analysis population if they were positive for BCL2::IGH rearrangement at enrolment in peripheral blood or bone marrow samples. MRD positivity was defined as the persistence of BCL2::IGH rearrangement in peripheral blood or bone marrow, assessed centrally by laboratories of the FIL MRD Network. The trial was registered with EudraCT, 2012-001676-11., Findings: Between May 2, 2015, and June 1, 2018, we enrolled 110 participants, of whom 106 (96%) were eligible and received involved-field radiotherapy. Of these, 105 (99%) were White, one (1%) was Black, 50 (47%) were male, and 56 (53%) were female. Of 105 participants in whom BCL2::IGH status was evaluable, 32 (30%) had a detectable BCL2::IGH rearrangement at baseline. After radiotherapy, 12 (40%) of 30 patients reached MRD-negative status, which was long-lasting (at least 36 or 42 months) in three (25%). In those who were MRD-positive after radiotherapy, ofatumumab induced MRD-negativity in 23 (92%; 95% CI 74-99) of 25 evaluable patients. After a median follow-up of 46·1 months (IQR 42·8-50·8), 14 (61%) of these 23 patients remain in complete response and are MRD-negative. The most common grade 3-4 adverse events were infusion-related reactions, observed in four patients., Interpretation: Local radiotherapy is frequently not associated with the eradication of follicular lymphoma. An MRD-driven, anti-CD20 monoclonal antibody consolidation enables molecular remission to be reached in almost all patients and is associated with a reduced incidence of relapse over time. A clinical advantage of an MRD-driven consolidation is therefore suggested., Funding: AIRC Foundation for Cancer Research in Italy, Novartis International, and GlaxoSmithKline., Competing Interests: Declaration of interests AP reports support for the study from Novartis and AIRC 5 × 1000; payment or honoraria for lectures or presentations from Takeda Pharmaceuticals, Roche, Janssen Pharmaceuticals, and BeiGene; payment for expert testimony from Takeda Pharmaceuticals and Roche; support for attending meetings and/or travel from Takeda Pharmaceuticals, Roche, Janssen Pharmaceuticals, BeiGene, Pfizer, and AbbVie; and participation on a data safety monitoring board or advisory board for Takeda Pharmaceuticals, Roche, and Janssen Pharmaceuticals.

Vaccinations are fundamental tools in preventing infectious diseases, especially in immunocompromised patients like those affected by non-Hodgkin lymphomas (NHLs). The COVID-19 pandemic made clinicians increasingly aware of the importance of vaccinations in preventing potential life-threatening SARS-CoV-2-related complications in NHL patients. However, several studies have confirmed a significant reduction in vaccine-induced immune responses after anti-CD20 monoclonal antibody treatment, thus underscoring the need for refined immunization strategies in NHL patients. In this review, we summarize the existing data about COVID-19 and other vaccine's efficacy in patients with NHL and propose multidisciplinary team-based recommendations for the management of vaccines in this specific group of patients., (© 2024 British Society for Haematology and John Wiley & Sons Ltd.)

Older patients with aggressive lymphoma are extremely heterogeneous due to the high frequency of functional limitations and comorbidities and to the different biological profiles and clinical behavior of the disease. The stratification in three geriatric categories (fit-unfit-frail) based on multidimensional geriatric assessment (GA) helps physicians tailor a potentially curative treatment.While an intensive approach with the standard R-CHOP regimen is feasible in fit patients, leading to similar long-term response and survival rates compared to younger ones, in unfit patients a balance between treatment toxicity and curative intent can be obtained through the reduction of dose intensity. Frail patients, treated with best supportive care so far, could benefit from a chemo-free approach with new target drugs. These novel agents, either alone or in combination with chemo-immunotherapy, are changing the therapeutic landscape of older patients with aggressive lymphoma, both in first-line therapy and in the setting of the relapsed/refractory disease.

Few data are known regarding the use of interim positron emission tomography (iPET) after the first two cycles (iPET2) of chemotherapy in treatment-naïve classical Hodgkin lymphoma (cHL) in routine clinical practice, and about the real-life adoption of intensification strategies for iPET positive patients. We conducted a multicenter retrospective study on cHL to investigate the use of iPET in the real-life setting, its prognostic role and outcomes of patients early shifted to intensification. Six hundreds and forty-one patients were enrolled (62% had advanced stage). iPET2 was positive in 89 patients (14%) including 8.7% and 17% early and advanced stage patients, respectively (p = 0.003). Among iPET 2 positive cases treatment was immediately modified in 19 cases; in 14 cases treatment was modified after an additional positive iPET4. Overall 56 iPET2 positive patients never received intensified therapies. Most frequently used intensified therapy was autologous stem cell transplantation followed by BEACOPP. After a median follow-up of 72 months, the 5-year progression-free survival (PFS) was 82% with iPET2 positive patients showing a worse PFS compared with iPET2 negative cases: 31% versus 85%. Focusing on advanced stage patients with a positive iPET2, the 5-year PFS was 59% for patients shifted to intensified therapy at any time point versus 61% for patients who never received intensified therapy. Our study confirmed the higher curability of naïve cHL patients in a real-world setting, and the prognostic role of iPET2 in this setting. A poor adherence to response-adapted strategy which however did not translate into a difference in patient outcomes., (© 2024 The Authors. Hematological Oncology published by John Wiley & Sons Ltd.)

Background: Marginal zone lymphomas (MZL), comprised of three unique but related subtypes, lack a unifying prognostic score applicable to all the patients in need for systemic chemotherapy and/or immunotherapy., Methods: Patients from the prospective NF10 study (NCT02904577) with newly diagnosed MZL and receiving frontline systemic therapy at diagnosis or after observation were used to train a prognostic model. The primary endpoint was progression-free survival (PFS) from start of treatment. The model was externally validated in a pooled analysis of two independent cohorts from the University of Iowa and Mayo Clinic Molecular Epidemiology Resource and the University of Miami., Findings: We identified 501 eligible patients. After multivariable modeling, lactate dehydrogenase (LDH) above upper normal limit, hemoglobin <12 g/dL, absolute lymphocyte count <1 × 10 9 /L, platelets <100 × 10 9 /L, and MZL subtype (nodal or disseminated) were independently associated with inferior PFS. The proposed MZL International Prognostic index (MZL-IPI) combined these 5 factors, and we defined low (LRG, 0 factors, 27%), intermediate (IRG, 1-2 factors, 57%) and high (HRG, 3+ factors, 16%) risk groups with 5-y PFS of 85%, 66%, and 37%, respectively (c-Harrell = 0.64). Compared to the LRG, the IRG (Hazard Ratio [HR] = 2.30, 95% CI 1.39-3.80) and HRG (HR = 5.41, 95% CI 3.12-9.38) had inferior PFS. Applying the MZL-IPI to the pooled US cohort (N = 353), 94 (27%), 192 (54%), and 67 (19%) patients were classified as LRG, IRG, and HRG, respectively, and the model was validated for PFS (log-rank test p = 0.0018; c-Harrell = 0.578, 95% CI 0.54-0.62). The MZL-IPI was also prognostic for OS in both the training and the external validation sets., Interpretation: MZL-IPI is a new prognostic score for use in all patients with MZL considered for systemic treatment., Funding: The MER was supported by P50 CA97274 and U01 CA195568., Competing Interests: LA: Grants or contracts from any entity: My First AIRC grant n. 11,415 2012–2014; Investigator Grant AIRC (2018–2022); Honoraria: EUSA Pharma, Novartis.

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported. We analyzed long-term results of the response-adapted trial for adult patients with advanced-stage Hodgkin lymphoma. The aim was to confirm noninferiority of treatment de-escalation by omission of bleomycin from doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) for interim fluorodeoxyglucose positron emission tomography (iPET)-negative patients and assess efficacy and long-term safety for iPET-positive patients who underwent treatment intensification with escalated bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisolone (BEACOPP/BEACOPP14). The median follow-up is 7.3 years. For all patients, the 7-year progression-free survival (PFS) and overall survival (OS) are 78.2% (95% CI, 75.6 to 80.5) and 91.6% (95% CI, 89.7 to 93.2), respectively. The 1.3% difference in 3-year PFS (95% CI, -3.0 to 4.7) between ABVD and doxorubicin, vinblastine, and dacarbazine (AVD) now falls within the predefined noninferiority margin. Among 172 patients with positive iPET, the 7-year PFS was 65.9% (95% CI, 58.1 to 72.6) and the 7-year OS was 83.2% (95% CI, 76.2 to 88.3). The cumulative incidence of second malignancies at 7 years was 5.5% (95% CI, 4.0 to 7.5) for those receiving ABVD/AVD and 2.5% (95% CI, 0.8 to 7.7) for those escalated to BEACOPP. With extended follow-up, these results confirm noninferiority of treatment de-escalation after a negative iPET. Escalation with BEACOPP for iPET-positive patients is effective and safe, with no increase in second malignancies.

The treatment choice for an older patient with diffuse large B-cell lymphoma (DLBCL) depends on many other factors in addition to age, which alone does not reflect the complexity of the aging process. Functional features and comorbidity incidence differ not only between younger and older patients but also among older patients themselves. The comprehensive geriatric assessment (CGA) quickly evaluates fitness status by investigating the patient's different functional areas, degree of autonomy, and presence of comorbidities. Various tools are available to evaluate frailty; which assessment tool to use should be based on the clinical aim. The simplified geriatric assessment (sGA) from the elderly project by the Fondazione Italiana Linfomi, prospectively tested on the largest number of patients, categorizes patients as fit, unfit, or frail, with a decreasing rate of overall survival. The elderly prognostic index (EPI), which combines sGA and IPI scores and hemoglobin level, is the first prognostic score for older patients, with three risk groups for survival. Future GAs should consider new parameters, including sarcopenia, which appears to be inversely related to survival. New tools based on prospective studies can help physicians choose the best treatment in light of the individual patient's characteristics.

Long non-coding RNA (lncRNA) are emerging as powerful and versatile regulators of transcriptional programs and distinctive biomarkers of progression of T-cell lymphoma. Their role in the aggressive anaplastic lymphoma kinase-negative (ALK-) subtype of anaplastic large cell lymphoma (ALCL) has been elucidated only in part. Starting from our previously identified ALCL-associated lncRNA signature and performing digital gene expression profiling of a retrospective cohort of ALCL, we defined an 11 lncRNA signature able to discriminate among ALCL subtypes. We selected a not previously characterized lncRNA, MTAAT, with preferential expression in ALK- ALCL, for molecular and functional studies. We demonstrated that lncRNA MTAAT contributes to an aberrant mitochondrial turnover restraining mitophagy and promoting cellular proliferation. Functionally, lncRNA MTAAT acts as a repressor of a set of genes related to mitochondrial quality control via chromatin reorganization. Collectively, our work demonstrates the transcriptional role of lncRNA MTAAT in orchestrating a complex transcriptional program sustaining the progression of ALK- ALCL.

Treatment of diffuse large B-cell lymphoma (DLBCL) in older patients is challenging, especially for those who are not eligible for anthracycline-containing regimens. Fondazione Italiana Linfomi (FIL) started the FIL&#95;ReRi study, a 2-stage single-arm trial to investigate the activity and safety of the chemo-free combination of rituximab and lenalidomide (R2) in ≥70-year-old untreated frail patients with DLBCL. Frailty was prospectively defined using a simplified geriatric assessment tool. Patients were administered a maximum of 6 28-day cycles of 20 mg oral lenalidomide from days 2 to 22 and IV rituximab 375 mg/m2 on day 1, with response assessment after cycles 4 and 6. Patients with partial response or complete response (CR) at cycle 6 were administered lenalidomide 10 mg/d from days 1 to 21 for every 28 cycles for a total of 12 cycles or until progression or unacceptable toxicity. The primary end point was the overall response rate (ORR) after cycle 6; the coprimary end point was the rate of grade 3 or 4 extrahematological toxicity. The ORR was 50.8%, with 27.7% CR. After a median follow-up of 24 months, the median progression-free survival was 14 months, and the 2-year duration of response was 64%. Thirty-four patients experienced extrahematological toxicity according to the National Cancer Institute Common Terminology Criteria for Adverse Events grade ≥3. The activity of the R2 combination was observed in a significant proportion of subjects, warranting further exploration of a chemo-free approach in frail older patients with DLBCL. This trial was registered at EudraCT as #2015-003371-29 and clinicaltrials.gov as #NCT02955823., (© 2023 by The American Society of Hematology.)

We conducted a post hoc analysis of the FOLL12 trial to determine the impact of different initial immunochemotherapy (ICT) regimens on patient outcomes. Patients were selected from the FOLL12 trial, which included adults with stage II-IV follicular lymphoma (FL) grade 1-3a and high tumor burden. Patients were randomized 1:1 to receive either standard ICT followed by rituximab maintenance (RM) or the same ICT followed by a response-adapted approach. ICT consisted of rituximab-bendamustine (RB) or rituximab, cyclophosphamide, doxorubicin, and prednisone (R-CHOP), per physician's decision. A total of 786 patients were included in this analysis, 341 of whom received RB and 445 R-CHOP. RB was more frequently prescribed to older subjects, females, patients without bulky disease, and those with grade 1-2 FL. After a median of 56 months of follow-up, R-CHOP and RB had similar progression-free survival (PFS) (Hazard Ratio for RB 1.11, 95% CI 0.87-1.42, p = 0.392). Standard RM was associated with improved PFS compared to response-adapted management both after R-CHOP and RB. Grade 3-4 hematologic adverse events were more frequent with R-CHOP during induction treatment and more frequent with RB during RM. Grade 3-4 infections were more frequent with RB. RB was also associated with a higher incidence of transformed FL. R-CHOP and RB showed similar activity and efficacy, but with different safety profiles and long-term events, suggesting that the treating physician should carefully select the most appropriate chemotherapy regimen for each patient based on patient's individual characteristics, choices, and risk profile., (© 2023 The Authors.

The natural history of limited-stage peripheral T-cell lymphomas (PTCLs) remains poorly defined. We investigated outcomes and prognostic variables in patients registered in the T-Cell Project (TCP) (#NCT01142674) to develop a model to predict overall survival (OS) for the common nodal PTCL subtypes (PTCL-NOS, AITL, ALCL). The model was validated in an independent data set from Australian and Brazilian registries. 211 patients registered in the TCP between 2006-2018 were studied. The median age was 59 years (range 18-88) and median follow-up was 49 months. One hundred twenty-seven patients (78%) received anthracycline-based regimens, 5 patients (3%) radiotherapy alone (RT), 24 patients (15%) chemotherapy+RT. 5-year OS and PFS were 47% and 37%, respectively. Age >60 years, elevated LDH and low serum albumin were independent prognostic factors. The model identified 3 groups with low- (26%, score 0), intermediate- (41%, score 1), and high-risk (33%, score 2-3) with 5-year OS of 78% (95% confidence interval [95% CI], 29-127), 46% (95% CI, 24-68), and 25% (95% CI, 20-30), respectively (P < 0.001) and 5-year PFS of 66% (95% CI, 33-99), 37% (95% CI, 9-65), and 17% (95% CI, 9-25), respectively (P < 0.001). The model demonstrated greater discriminatory power than established prognostic indices and an analogous distribution and outcomes in the 3 groups in the validation cohort of 103 patients. The SALENTO Model (Limited Stage Peripheral T-Cell Lymphoma Prognostic Model) is an objective, simple and robust prognostic tool. The high-risk group has poor outcomes, comparable to advanced stage disease, and should be considered for innovative first-line approaches., (© 2023 by The American Society of Hematology.

Rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) is the most commonly used regimen for the upfront treatment of diffuse large B-cell lymphoma (DLBCL). However, it is associated with cardiotoxicity, especially in older patients. Substituting doxorubicin with non-PEGylated liposomal doxorubicin (R-COMP) may reduce the risk of cardiac events, but its efficacy has never been demonstrated in prospective trials. We describe the characteristics and outcome of patients with DLBCL aged ≥65 years prospectively enrolled in the Elderly Project by the Fondazione Italiana Linfomi and treated with full doses of R-CHOP or R-COMP per local practice. Starting from 1163 patients, 383 (55%) were treated with R-CHOP and 308 (45%) with R-COMP. Patients treated with R-COMP were older (median age, 76 vs 71 years), less frequently fit at simplified geriatric assessment (61% vs 88%; P < .001), and had a more frequent baseline cardiac disorders (grade >1, 32% vs 8%; P < .001). Three-year progression-free survival (PFS) was similar between R-CHOP and R-COMP (70% and 64%); 3-year overall survival was 77%, and 71% respectively. R-CHOP was associated with better PFS vs R-COMP only in the Elderly Prognostic Index (EPI) low-risk group. The two groups had similar rates of treatment interruptions due to toxicities or of cardiac events (P = 1.00). We suggest R-COMP is a potentially curative treatment for older patients with intermediate- or high-risk EPI, even in the presence of a baseline cardiopathy. R-CHOP is confirmed as the standard therapy for low risk patients., (© 2023 by The American Society of Hematology.

Objectives: The aim of this study was to compare the prevalence, entity and local distribution of arterial wall calcifications evaluated on CT scans in patients with large vessel vasculitis (LVV) and patients with lymphoma as reference for the population without LVV., Methods: All consecutive patients diagnosed with LVVs with available baseline positron emission tomography-CT (PET-CT) scan performed between 2007 and 2019 were included; non-LVV patients were lymphoma patients matched by age (±5 years), sex and year of baseline PET-CT (≤2013; >2013). CT images derived from baseline PET-CT scans of both patient groups were retrospectively reviewed by a single radiologist who, after setting a threshold of minimum 130 Hounsfield units, semiautomatically computed vascular calcifications in three separate locations (coronaries, thoracic and abdominal arteries), quantified as Agatston and volume scores., Results: A total of 266 patients were included. Abdominal artery calcifications were equally distributed (mean volume 3220 in LVVs and 2712 in lymphomas). Being in the LVVs group was associated with the presence of thoracic calcifications after adjusting by age and year of diagnosis (OR 4.13, 95% CI 1.35 to 12.66; p=0.013). Similarly, LVVs group was significantly associated with the volume score in the thoracic arteries (p=0.048). In patients >50 years old, calcifications in the coronaries were more extended in non-LVV patients (p=0.027 for volume)., Conclusion: When compared with patients without LVVs, LVVs patients have higher calcifications in the thoracic arteries, but not in coronary and abdominal arteries., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Background: Hematological malignancies (HMs) represent a heterogeneous group of diseases with diverse etiology, pathogenesis, and prognosis. HMs' accurate registration by Cancer Registries (CRs) is hampered by the progressive de-hospitalization of patients and the transition to molecular rather than microscopic diagnosis., Material and Methods: A dedicated software capable of automatically identifying suspected HMs cases by combining several databases was adopted by Reggio Emilia Province CR (RE-CR). Besides pathological reports, hospital discharge archives, and mortality records, RE-CR retrieved information from general and biomolecular laboratories. Incidence, mortality, and 5-year relative survival (RS) reported according to age, sex, and 4 HMs' main categories, were noted., Results: Overall, 7,578 HM cases were diagnosed from 1996 to 2020 by RE-CR. HMs were more common in males and older patients, except for Hodgkin Lymphoma and Follicular Lymphoma (FL). Incidence showed a significant increase for FL (annual percent change (APC)=3.0), Myeloproliferative Neoplasms (MPN) in the first period (APC=6.0) followed by a significant decrease (APC=-7.4), and Myelodysplastic Syndromes (APC=16.4) only in the first period. Over the years, a significant increase was observed in 5-year RS for Hodgkin -, Marginal Zone -, Follicular - and Diffuse Large B-cell-Lymphomas, MPN, and Acute Myeloid Leukemia. The availability of dedicated software made it possible to recover 80% of cases automatically: the remaining 20% required direct consultation of medical records., Conclusions: The study emphasizes that HM registration needs to collect information from multiple sources. The digitalization of CRs is necessary to increase their efficiency., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Mangone, Penna, Marinelli, Roncaglia, Bisceglia, Merli, Ruffini, Gamberi, Tieghi, Valli, Albertazzi, Iori, Giorgi Rossi, Vener, Morabito, Neri and Luminari.)

Given the paucity of high-certainty evidence, and differences in opinion on the use of nuclear medicine for hematological malignancies, we embarked on a consensus process involving key experts in this area. We aimed to assess consensus within a panel of experts on issues related to patient eligibility, imaging techniques, staging and response assessment, follow-up, and treatment decision-making, and to provide interim guidance by our expert consensus. We used a three-stage consensus process. First, we systematically reviewed and appraised the quality of existing evidence. Second, we generated a list of 153 statements based on the literature review to be agreed or disagreed with, with an additional statement added after the first round. Third, the 154 statements were scored by a panel of 26 experts purposively sampled from authors of published research on haematological tumours on a 1 (strongly disagree) to 9 (strongly agree) Likert scale in a two-round electronic Delphi review. The RAND and University of California Los Angeles appropriateness method was used for analysis. Between one and 14 systematic reviews were identified on each topic. All were rated as low to moderate quality. After two rounds of voting, there was consensus on 139 (90%) of 154 of the statements. There was consensus on most statements concerning the use of PET in non-Hodgkin and Hodgkin lymphoma. In multiple myeloma, more studies are required to define the optimal sequence for treatment assessment. Furthermore, nuclear medicine physicians and haematologists are awaiting consistent literature to introduce volumetric parameters, artificial intelligence, machine learning, and radiomics into routine practice., Competing Interests: Declaration of interests IB has received research grants from Dosisoft, GE Healthcare, and Siemens Healthineers, and is a member of the Society of Nuclear Medicine and Molecular Imaging Artificial Intelligence Task Force.

Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is a rare entity whose neoplastic cells retain a B-cell phenotype with expression of CD20. Radiotherapy is recommended for favorable stage IA disease while for other stages guidelines suggest therapeutic strategies similar to those used for classic HL. The role of rituximab, although quite widespread, is not completely elucidated. We retrospectively analyzed baseline characteristics of 308 consecutive patients with NLPHL diagnosed in 19 Italian centers from 2000 to 2018. With a median follow-up of 8.4 years (interquartile range: 4.5-12.4) for treated patients, median overall survival (OS) was not reached and estimated 5-year OS was 97.8% and 5-year progression-free survival (PFS) was 84.5%. Five-year cumulative incidence of histological transformation was 1.4%, 95% confidence interval (CI), 0.5%-3.8%. After adjusting for lymphocyte count, splenic involvement, bulky disease and B symptoms (fever, drenching night sweats, unintentional loss >10% of body weight within the preceding 6 months), patients with stage II or more showed superior PFS with immunochemotherapy in comparison to chemotherapy alone (hazard ratio = 0.4, 95% CI, 0.2-0.8; P = 0.015). Our data suggest an advantage of the use of rituximab combined with chemotherapy ± radiotherapy in the treatment of stage II-III-IV NLPHL., Competing Interests: LA received advisory honoraria from Roche, Celgene, Janssen-Cilag, Verastem, Eusa Pharma, and Incyte, research support from Gilead, and travel expenses from Roche, Celgene, Janssen-Cilag, and Eusa Pharma, speakers bureau from Novartis.

Octogenarian patients with diffuse large B-cell lymphoma are managed mainly with palliation, but recent improvement in their overall condition makes potentially curative treatment a possibility. Studies have shown that half of selected octogenarians may be cured using reduced-dose anthracycline chemoimmunotherapy. However, patients aged >85 (late octogenarians [LO]) were underrepresented, and selection criteria were poorly defined. We analyzed the clinical characteristics and outcomes of LO enrolled in the FIL Elderly Project in terms of the treatment received (palliative vs. curative) and of their simplified geriatric assessment (sGA), then compared them with early octogenarians (EO) aged 80- 84 and with those aged 65-79 classified as UNFIT or FRAIL according to sGA enrolled in the same study. Of the 1,163 patients, 370 were >80 and 129 LO. Clinical characteristics were similar between LO and EO, but LO more frequently received palliation (50% vs. 23%; P=0.001) and had worse 2-year overall survival (OS) (48% vs. 63%; P=0.001) and 2-year progression-free survival (PFS) (43% vs. 56%; P=0.01). Patients receiving anthracycline did better than patients receiving palliation (P<0.001), without any difference between full or reduced doses. Rituximab within palliation improved outcome (2-yr OS with or without rituximab 42% vs. 22%; P=0.008). Elderly Prognostic Index (EPI) performed better than sGA in identifying different risk categories, and high-risk EPI retained an independent unfavorable effect on OS and PFS, together with treatment without anthracycline. In conclusion, late octogenarians can benefit from a curative approach with reduced-dose anthracycline and from rituximab within palliation. EPI may help in patient selection more than sGA can.

Patients with hematologic malignancies can be immunocompromized because of their disease, anti-cancer therapy, and concomitant immunosuppressive treatment. Furthermore, these patients are usually older than 60 years and have comorbidities. For all these reasons they are highly vulnerable to infection with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and have an increased risk of developing severe/critical Coronavirus disease 2019 (COVID-19) compared to the general population. Although COVID-19 vaccination has proven effective in reducing the incidence of severe/critical disease, vaccinated patients with lymphoma may not be protected as they often fail to develop a sufficient antiviral immune response. There is therefore an urgent need to address the management of patients with lymphoma and COVID-19 in the setting of the ongoing pandemic. Passive immunization with monoclonal antibodies against SARS-CoV-2 is a currently available complementary drug strategy to active vaccination for lymphoma patients, while monoclonal antibodies and antiviral drugs (remdesivir, ritonavir-boosted nirmatrelvir, and molnupiravir) have proven effective in preventing the progression to severe/critical COVID-19. In this narrative review we present the most recent data documenting the characteristics and outcomes of patients with concomitant lymphoma and COVID-19. Our ultimate goal is to provide practice-oriented guidance in the management of these vulnerable patients from diagnosis to treatment and follow-up of lymphoma. To this purpose, we will first provide an overview of the main data concerning prognostic factors and fatality rate of lymphoma patients who develop COVID-19; the outcomes of COVID-19 vaccination will also be addressed. We will then discuss current COVID-19 prophylaxis and treatment options for lymphoma patients. Finally, based on the literature and our multidisciplinary experience, we will summarize a set of indications on how to manage patients with lymphoma according to COVID-19 exposure, level of disease severity and former history of infection, as typically encountered in clinical practice., (© 2022 The Authors.

The Elderly Prognostic Index (EPI) is based on the integration of a simplified geriatric assessment, hemoglobin levels and International Prognostic Index and has been validated to predict overall survival in older patients with diffuse large B-cell lymphoma (DLBCL). In this study, we evaluated the ability of EPI to predict the risk of early mortality. This study included all patients registered in the Elderly Project for whom treatment details and a minimum follow-up of 3 months were available. Three main treatment groups were identified based on the anthracycline amount administered: cases receiving >70% of the theoretical anthracyclines dose (Full Dose [FD] group), ≤70% (Reduced Dose [RD]) and palliative therapy (PT; no anthracyclines). The primary endpoint was early mortality rate, defined as death for any cause occurring within 90 days from diagnosis. We identified 1150 patients with a median age of 76 years (range 65-94). Overall, 69 early deaths were observed, accounting for 19% of all reported deaths. The cumulative rate of early mortality at 90 days was 6.0%. Comparing early with delayed deaths, we observed a lower frequency of deaths due to lymphoma progression (42% vs. 75%; p < 0.001) and a higher frequency due to toxicity and infections (22% vs. 4%, p < 0.001, and 22% vs. 3%, p < 0.001, respectively) for early events. A multivariable logistic analysis on 931 patients (excluding PT) confirmed an independent association of high-risk EPI (odds ratio [OR] 3.60; 95% confidence interval [CI] 1.15-11.2) and bulky disease (OR 2.08; 95% CI 1.09-3.97) with the risk of early mortality. The cumulative incidence of early mortality for older patients with DLBCL is not negligible and is mainly associated with non-lymphoma related events. For patients receiving anthracyclines, high-risk EPI and bulky disease are associated with a higher probability of early mortality., (© 2022 John Wiley & Sons Ltd.)

The immune system plays a central role in the onset and progression of cancer. A better understanding of transcriptional changes in immune cell-related genes associated with cancer progression, and their significance in disease prognosis, is therefore needed. NanoString-based targeted gene expression profiling has advantages for deployment in a clinical setting over RNA-seq technologies. We analysed NanoString PanCancer Immune Profiling panel gene expression data encompassing 770 genes, and overall survival data, from multiple previous studies covering 10 different cancer types, including solid and blood malignancies, across 515 patients. This analysis revealed an immune gene signature comprising 39 genes that were upregulated in those patients with shorter overall survival; of these 39 genes, three (MAGEC2, SSX1 and ULBP2) were common to both solid and blood malignancies. Most of the genes identified have previously been reported as relevant in one or more cancer types. Using Cibersort, we investigated immune cell levels within individual cancer types and across groups of cancers, as well as in shorter and longer overall survival groups. Patients with shorter survival had a higher proportion of M2 macrophages and γδ T cells. Patients with longer overall survival had a higher proportion of CD8+ T cells, CD4+ T memory cells, NK cells and, unexpectedly, T regulatory cells. Using a transcriptomics platform with certain advantages for deployment in a clinical setting, our multi-cancer meta-analysis of immune gene expression and overall survival data has identified a specific transcriptional profile associated with poor overall survival., Competing Interests: The authors have declared that no competing interests exist., (Copyright: This is an open access article, free of all copyright, and may be freely reproduced, distributed, transmitted, modified, built upon, or otherwise used by anyone for any lawful purpose.

Purpose: We prospectively treated patients with hepatitis C virus (HCV)-associated indolent lymphomas with genotype-appropriate direct-acting antivirals (DAAs) with the aim to evaluate virologic and hematologic outcomes. No prospective studies in this setting have been published so far., Methods: FIL&#95;BArT is a prospective, multicenter, phase II trial that evaluated genotype-appropriate DAAs in untreated HCV-positive patients with indolent lymphomas without criteria for immediate conventional antilymphoma treatment. The primary objective was sustained virologic response, whereas the main secondary objectives were overall response rate of lymphoma and progression-free survival., Results: Forty patients were enrolled, including 27 with marginal zone lymphoma. Median age was 68 years. Extranodal sites were involved in 14 cases (35%). Main genotypes were 1 in 16 patients and 2 in 21 patients. All patients received genotype-guided DAAs: 17 ledipasvir/sofosbuvir, eight sofosbuvir plus ribavirin, and 15 sofosbuvir/velpatasvir. All patients achieved sustained virologic response (100%). DAAs were well tolerated, with only two grade 3-4 adverse events. Overall response rate of lymphoma was 45%, including eight patients (20%) achieving complete response and 10 (25%) partial response, whereas 16 exhibited stable disease and six progressed. With a median follow-up of 37 months, two patients died (3-year overall survival 93%; 95% CI, 74 to 98) and three additional patients progressed, with a 3-year progression-free survival of 76% (95% CI, 57 to 87)., Conclusion: HCV eradication by DAAs was achieved in 100% of HCV-positive patients with indolent lymphomas not requiring immediate conventional treatment and resulted in non-negligible rate of lymphoma responses. Treatment with DAAs should be considered as the first-line therapy in this setting.

The T-cell Lymphoma Project is an international registry prospective study that enrolled patients with newly diagnosed peripheral T-cell and NK-cell lymphomas (PTCL). The main objective was to define the clinical features and outcomes, establishing a robust benchmark for future clinical trials. Seventy-four institutions from 14 countries in North America, South America, Europe, and Asia collected data on patients diagnosed and treated at their respective centers between September 2006 and February 2018. Among 1553 PTCL patients, 131 (8.4% of the total cohort) were confirmed to have anaplastic large cell lymphoma - kinase positive (ALCL, ALK+). The median age of the patients was 39 years (18-84). Sixty-five patients (66%) had advanced-stage disease, although majority (45 patients, 54%) had a low-risk International Prognostic Index (IPI) score (0-1). Of 97 patients treated with chemotherapy, 97% received anthracycline-containing regimens. The overall response rate was 81%, with 69 patients (70%) achieving complete remission. Estimated OS and PFS at 3 years were 77% (95% CI: 54%-99%) and 68% (95% CI: 46%-90%), respectively, and at 5 years were very similar, 77% of OS (95% CI: 62%-92%) and 64% of PFS (95% CI: 34%-94%). Multivariate analysis for PFS showed advanced stage (hazard ratios [HR]: 4.72, 95% CI: 1.43-23.9, p = 0.015), elevated lactate dehidrogenade (LDH) (HR 4.85; 95% CI: 1.73-13.60, p = 0.001), and Eastern Cooperative Oncology Group Performance Status scale (ECOG-PS) ≥2 (HR: 5.25; 95% CI: 1.68-16.4, p = 0.024). For OS, elevated LDH (HR: 3.77; 95% CI: 1.98-14.17, p = 0.014) and ECOG-PS ≥2 (HR: 4.59; 95% CI: 1.46-14.39, p = 0.004) were identified. In summary, although the outcome of ALK+ ALCL is superior to that of other PTCLs, it remains sufficiently favorable, given the young median age of the patients. Our results confirm the usefulness of both IPI and Prognostic Index for T-cell Lymphoma (PIT) in identifying groups of patients with different outcomes.

We evaluated the prognostic role of the largest distance between two lesions (Dmax), defined by positron emission tomography (PET) in a retrospective cohort of newly diagnosed classical Hodgkin Lymphoma (cHL) patients. We also explored the molecular bases underlying Dmax through a gene expression analysis of diagnostic biopsies. We included patients diagnosed with cHL from 2007 to 2020, initially treated with ABVD, with available baseline PET for review, and with at least two FDG avid lesions. Patients with available RNA from diagnostic biopsy were eligible for gene expression analysis. Dmax was deduced from the three-dimensional coordinates of the baseline metabolic tumor volume (MTV) and its effect on progression free survival (PFS) was evaluated. Gene expression profiles were correlated with Dmax and analyzed using CIBERSORTx algorithm to perform deconvolution. The study was conducted on 155 eligible cHL patients. Using its median value of 20 cm, Dmax was the only variable independently associated with PFS (HR = 2.70, 95% CI 1.1-6.63, pValue = 0.03) in multivariate analysis of PFS for all patients and for those with early complete metabolic response (iPET-). Among patients with iPET-low Dmax was associated with a 4-year PFS of 90% (95% CI 82.0-98.9) significantly better compared to high Dmax (4-year PFS 72.4%, 95% CI 61.9-84.6). From the analysis of gene expression profiles differences in Dmax were mostly associated with variations in the expression of microenvironmental components. In conclusion our results support tumor dissemination measured through Dmax as novel prognostic factor for cHL patients treated with ABVD., (© 2022 The Authors.

Purpose: To investigate the role of combined systemic and local chemotherapy in improving the survival of patients with vitreoretinal lymphoma (VRL)., Methods: Patients with VRL consecutively seen from 2006 to 2020 were retrospectively reviewed; data on the presence and time of central nervous system (CNS) involvement and treatment regimen (systemic, local or combined chemotherapy) were collected. Overall survival (OS) and progression-free survival (PFS) were calculated for each group., Results: Forty-three eyes of 22 subjects with histology-proven VRL were included. Mean time of survival was 64.8 months (SE±10.8). Twelve patients (57%) presented CNS involvement, which was significantly associated with progression (r = 0.48, P = .03) and death (r = 0.56, P = .009). The isolated primary VRL group had a 5-year OS of 80%. Combined systemic and local chemotherapy reduced the risk of death by 82% (hazard ratio 0.18[0.04- 0.85]) in the entire cohort., Conclusion: Combined systemic and local chemotherapy significantly improved OS but not PFS of patients affected by VRL.

Extranodal marginal zone lymphoma (EMZL) is a heterogeneous non-Hodgkin lymphoma. No consensus exists regarding the standard-of-care in patients with advanced-stage disease. Current recommendations are largely adapted from follicular lymphoma, for which bendamustine with rituximab (BR) is an established approach. We analyzed the safety and efficacy of frontline BR in EMZL using a large international consortium. We included 237 patients with a median age of 63 years (range, 21-85). Most patients presented with Eastern Cooperative Oncology Group (ECOG) performance status 0 to 1 (n = 228; 96.2%), stage III/IV (n = 179; 75.5%), and intermediate (49.8%) or high (33.3%) Mucosa Associated Lymphoid Tissue International Prognosis Index (MALT-IPI). Patients received a median of 6 (range, 1-8) cycles of BR, and 20.3% (n = 48) received rituximab maintenance. Thirteen percent experienced infectious complications during BR therapy; herpes zoster (4%) was the most common. Overall response rate was 93.2% with 81% complete responses. Estimated 5-year progression-free survival (PFS) and overall survival (OS) were 80.5% (95% CI, 73.1% to 86%) and 89.6% (95% CI, 83.1% to 93.6%), respectively. MALT-IPI failed to predict outcomes. In the multivariable model, the presence of B symptoms was associated with shorter PFS. Rituximab maintenance was associated with longer PFS (hazard ratio = 0.16; 95% CI, 0.04-0.71; P = .016) but did not impact OS. BR is a highly effective upfront regimen in EMZL, providing durable remissions and overcoming known adverse prognosis factors. This regimen is associated with occurrence of herpes zoster; thus, prophylactic treatment may be considered., (© 2022 by The American Society of Hematology.

Purpose: We compared 2 years of rituximab maintenance (RM) with a response-adapted postinduction approach in patients with follicular lymphoma who responded to induction immunochemotherapy., Methods: We randomly assigned treatment-naïve, advanced-stage, high-tumor burden follicular lymphoma patients to receive standard RM or a response-adapted postinduction approach on the basis of metabolic response and molecular assessment of minimal residual disease (MRD). The experimental arm used three types of postinduction therapies: for complete metabolic response (CMR) and MRD-negative patients, observation; for CMR and MRD-positive (end of induction or follow-up) patients, four doses of rituximab (one per week, maximum three courses) until MRD-negative; and for non-CMR patients, one dose of ibritumomab tiuxetan followed by standard RM. The study was designed as noninferiority trial with progression-free survival (PFS) as the primary end point., Results: Overall, 807 patients were randomly assigned. After a median follow-up of 53 months (range, 1-92 months), patients in the standard arm had a significantly better PFS than those in the experimental arm (3-year PFS 86% v 72%; P < .001). The better PFS of the standard versus experimental arm was confirmed in all the study subgroups except non-CMR patients (n = 65; P = .274). The 3-year overall survival was 98% (95% CI, 96 to 99) and 97% (95% CI, 95 to 99) in the reference and experimental arms, respectively ( P = .238)., Conclusion: A metabolic and molecular response-adapted therapy as assessed in the FOLL12 study was associated with significantly inferior PFS compared with 2-year RM. The better efficacy of standard RM was confirmed in the subgroup analysis and particularly for patients achieving both CMR and MRD-negative., Competing Interests: Stefano LuminariConsulting or Advisory Role: Roche, Gilead Sciences, Celgene, Genmab, Regeneron, IncyteTravel, Accommodations, Expenses: Janssen, Celgene Sara GalimbertiSpeakers' Bureau: Novartis Italy, Jazz Pharmaceuticals, Incyte, AbbVieTravel, Accommodations, Expenses: Jazz Pharmaceuticals, Janssen Oncology, Incyte, Novartis Italy Annibale VersariConsulting or Advisory Role: NovartisTravel, Accommodations, Expenses: Novartis Alessandra TucciConsulting or Advisory Role: Janssen, TakedaTravel, Accommodations, Expenses: Sandoz Luigi MarcheselliUncompensated Relationships: Sandoz SpA Simone FerreroConsulting or Advisory Role: Janssen-Cilag, EUSA Pharma, Clinigen Group, IncyteSpeakers' Bureau: Janssen-Cilag, Servier, EUSA Pharma, GentiliResearch Funding: Gilead Sciences (Inst), MorphoSys (Inst), Janssen (Inst)Travel, Accommodations, Expenses: Roche, Servier, Sanofi, Janssen-Cilag, EUSA Pharma, Gentili Luca ArcainiConsulting or Advisory Role: Roche, Janssen-Cilag, Verastem, Incyte, EUSA Pharma, Celgene/Bristol Myers SquibbSpeakers' Bureau: EUSA PharmaResearch Funding: Gilead SciencesTravel, Accommodations, Expenses: Roche, Celgene, Janssen-Cilag, EUSA Pharma Federica CavalloHonoraria: ServierConsulting or Advisory Role: Gilead Sciences, RocheTravel, Accommodations, Expenses: Celgene Tetiana SkrypetsHonoraria: Takeda Ilaria del GiudiceConsulting or Advisory Role: Tolero Pharmaceuticals, AstraZeneca Stephane ChauvieStock and Other Ownership Interests: DixitHonoraria: Sirtex MedicalSpeakers' Bureau: TERUMO, Sirtex MedicalResearch Funding: Roche Antonello PintoHonoraria: Roche/Genentech, Merck Sharp & Dohme, Bristol Myers Squibb, Celgene, Servier, IncyteConsulting or Advisory Role: Servier, Roche/Genentech, Merck, TakedaSpeakers' Bureau: Roche/Genentech Marco LadettoHonoraria: AbbVie, Amgen, ADC Therapeutics, BeiGene, Celgene, Gentili, Kite/Gilead, Novartis, Incyte, Janssen, Jazz Pharmaceuticals, Regeneron, RocheConsulting or Advisory Role: Jazz Pharmaceuticals, Roche, Janssen, Regeneron, Gilead Sciences, Novartis, IncyteSpeakers' Bureau: IncyteResearch Funding: ADC Therapeutics (Inst), Janssen (Inst) Annalisa ChiarenzaConsulting or Advisory Role: Roche/Genentech Annalisa ArcariConsulting or Advisory Role: Janssen-CilagTravel, Accommodations, Expenses: Janssen-Cilag, Takeda Massimo FedericoConsulting or Advisory Role: Takeda, Menarini, Erytech Pharma, MedivationTravel, Accommodations, Expenses: Takeda Pharmaceutical Taiwan, LTDNo other potential conflicts of interest were reported.

The standard management for relapsed or refractory classical Hodgkin lymphoma (cHL) is salvage therapy followed by autologous stem cell transplantation (ASCT). This strategy allows almost 50% of patients to be cured. Post-ASCT maintenance treatment with brentuximab vedotin (BV) confers improved progression-free survival (PFS) to cHL patients at high risk of relapse. We investigated the outcome of 105 cHL patients receiving post-ASCT BV maintenance in the real-life setting of 23 Italian hematology centers. This population included naïve patients and those previously exposed to BV. Median follow-up was 20 months. Patients presented a median of two lines of treatment pre-ASCT, with 51% receiving BV. Twenty-nine percent of patients had at least two high-risk factors (refractory disease, complete response [CR] less than 12 months, extranodal disease at relapse), while 16% presented none. At PET-CT, a Deauville score (DS) of 1-3 was reported in 75% and 78% of pre- and post-ASCT evaluations, respectively. Grade 3-4 adverse events (AEs), mainly peripheral neuropathy, were observed in 16% of patients. Three-year PFS and overall survival (OS) were 62% and 86%, respectively. According to BV exposure, 3-year PFS and OS were 54% and 71%, respectively, for naïve and 77% and 96%, respectively, for previously exposed patients. Refractory disease (hazard ratio [HR] 4.46; p = 0.003) and post-ASCT DS 4-5 (HR 3.14; p = 0.005) were the only two factors significantly associated with PFS reduction in multivariable analysis. Post-ASCT BV maintenance is an effective, safe treatment option for cHL naïve patients and those previously exposed to BV., (© 2021 The Authors.

Patients with relapsed/refractory (R/R) peripheral T-cell lymphoma (PTCL) have a poor prognosis, with an expected survival of less than 1 year using standard salvage therapies. Recent advances in our understanding of the biology of PTCL have led to identifying B-Cell Lymphoma 2 (BCL2) protein as a potential therapeutic target. BLC2 inhibitor venetoclax was investigated in a prospective phase II trial in patients with BCL2-positive R/R PTCL after at least one previous standard line of treatment (NCT03552692). Venetoclax given alone at a dosage of 800 mg/day resulted in one complete response (CR) and two stable diseases (SDs) among 17 enrolled patients. The majority of patients (88.2%) interrupted the treatment due to disease progression. No relationship with BCL2 expression was documented. At a median follow-up of 8 months, two patients are currently still on treatment (one CR and one SD). No case of tumor lysis syndrome was registered. Therefore, venetoclax monotherapy shows activity in a minority of patients whose biological characteristics have not yet been identified., Clinical Trial Registration: www.clinicaltrials.gov (NCT03552692, EudraCT number 2017-004630-29)., Competing Interests: PZ has received advisory board fees from Secura Bio, Celltrion, Gilead, Janssen-Cilag, BMS, Servier, Sandoz, MSD, TG Therapeutics, Takeda, Roche, Eusapharma, Kyowa Kirin, Novartis, ADC Therapeutics, Incyte, and Beigene; received consultant fees from MSD, Eusapharma, and Novartis; and received speaker’s bureau fees from Celltrion, Gilead, Janssen-Cilag, BMS, Servier, MSD, TG Therapeutics, Takeda, Roche, Eusapharma, Kyowa Kirin, Novartis, Incyte, and Beigene.

Minimal residual disease (MRD) monitoring by PCR methods is a strong and standardized predictor of clinical outcome in mantle cell lymphoma (MCL) and follicular lymphoma (FL). However, about 20% of MCL and 40% of FL patients lack a reliable molecular marker, being thus not eligible for MRD studies. Recently, targeted locus amplification (TLA), a next-generation sequencing (NGS) method based on the physical proximity of DNA sequences for target selection, identified novel gene rearrangements in leukemia. The aim of this study was to test TLA in MCL and FL diagnostic samples lacking a classical, PCR-detectable, t(11; 14) MTC (BCL1/IGH), or t(14; 18) major breakpoint region and minor cluster region (BCL2/IGH) rearrangements. Overall, TLA was performed on 20 MCL bone marrow (BM) or peripheral blood (PB) primary samples and on 20 FL BM, identifying a novel BCL1 or BCL2/IGH breakpoint in 16 MCL and 8 FL patients (80% and 40%, respectively). These new breakpoints (named BCL1-TLA and BCL2-TLA) were validated by ASO primers design and compared as MRD markers to classical IGH rearrangements in eight MCL: overall, MRD results by BCL1-TLA were superimposable (R Pearson = 0.76) to the standardized IGH-based approach. Moreover, MRD by BCL2-TLA reached good sensitivity levels also in FL and was predictive of a primary refractory case. In conclusion, this study offers the proof of principle that TLA is a promising and reliable NGS-based technology for the identification of novel molecular markers, suitable for further MRD analysis in previously not traceable MCL and FL patients., (© 2021 The Authors.

Biosimilars are biologic drug products that are highly similar to reference products in analytic features, pharmacokinetics and pharmacodynamics, immunogenicity, safety, and efficacy. Biosimilar epoetin received Food and Drug Administration (FDA) approval in 2018. The manufacturer received an FDA nonapproval letter in 2017, despite receiving a favorable review by FDA's Oncologic Drugs Advisory Committee (ODAC) and an FDA nonapproval letter in 2015 for an earlier formulation. We discuss the 2018 FDA approval, the 2017 FDA ODAC Committee review, and the FDA complete response letters in 2015 and 2017; review concepts of litigation, naming, labeling, substitution, interchangeability, and pharmacovigilance; review European and U.S. oncology experiences with biosimilar epoetin; and review the safety of erythropoiesis-stimulating agents. In 2020, policy statements from AETNA, United Health Care, and Humana indicated that new epoetin oncology starts must be for biosimilar epoetin unless medical need for other epoetins is documented. Empirical studies report that as of 2012, reference epoetin use decreased from 40%-60% of all patients with cancer with chemotherapy-induced anemia to <5% of such patients because of safety concerns. Between 2018 and 2020, biosimilar epoetin use varied, increasing to 81% among one private insurer's patients covered by Medicare whose cancer care is administered with Oncology Analytics and to 41% with the same private insurer's patients with cancer covered by commercial health insurance and administered by the private insurer, to 0% in several Veterans Administration Hospitals, increasing to 100% in one large county hospital in California, and with yet-to-be-reported data from most oncology settings. We conclude that biosimilar epoetin appears to have overcome some barriers since 2015, although current uptake in the U.S. is variable. Pricing and safety considerations for all erythropoiesis-stimulating agents are primary determinants of biosimilar epoetin oncology uptake. IMPLICATIONS FOR PRACTICE: Few oncologists understand substitution and interchangeability of biosimilars with reference drugs. Epoetin biosimilar is new to the market, and physician and patient understanding is limited. The development of epoetin biosimilar is not familiar to oncologists., (© 2021 AlphaMed Press.)

Non-Hodgkin lymphomas (NHL) are most commonly diagnosed among people aged 65-74 years, with a median age at diagnosis of 67 years. The percentage of NHL-related deaths is highest among people aged 75-84 years, with a median age at death of 76 years from cases between 2014 and 2018. In light of these recent data, attending physicians of patients with NHL will recognize that the majority of their patients will be of advanced age, with many suffering from a spectrum of frailties. The excess rate of death among older adults with NHL may be related to a range of different factors such as more challenging biologic features, undertreatment received due to a patient's chronology and treatment-related toxicity. The aim of this review is to provide an updated overview of the knowledge generated over recent years regarding epidemiology, prognosis and treatment options in older adults with lymphoma, focusing on Diffuse Large B-cell Lymphoma (DLBCL) where the most robust evidence base is available., (© 2021 British Society for Haematology and John Wiley & Sons Ltd.)

iTLPD-GI is a low-grade clonal T-cell lymphoproliferative disease arising in GI organs. It is an uncommon disease, and only recently has it been enlisted as a distinct provisional entity in the current WHO Classification. Data from the literature disclose high heterogeneity in terms of pathological and molecular features; on the other hand, establishing an accurate diagnosis of iTLPD-GI is of pivotal importance, since treatment options are different from that of other, more frequent lymphomas that arise in the gastrointestinal tract. In this review, we aimed to better define this novel entity, and to identify useful diagnostic biomarkers; moreover, we provide a biomarker-based approach to the diagnosis and describe the most common issues in differentiating iTLPD-GI from other neoplastic and non-neoplastic disorders.

Peripheral T-cell lymphomas (PTCLs) are a rare, heterogeneous group of hematological malignancies with extremely poor prognosis for almost all subtypes. The diverse clinicopathological features of PTCLs make accurate diagnosis, prognosis, and choice of optimal treatment strategies difficult. Moreover, the best therapeutic algorithms are still under debate due to the extrapolated approaches developed for B-cell lymphomas and to the absence of few treatment protocol specifically developed for PTCLs. Some advances have been made with CD30 monoclonal antibody, mainly for anaplastic large-cell lymphomas, with improvements in progression-free survival and overall survival. Several new drugs are under evaluation in clinical trials, although not all the results are as encouraging as expected. In this review, we briefly present the most updated information on diagnosis, prognostication, and treatment strategies in PTCLs., (© 2021 The Authors. Hematological Oncology published by John Wiley & Sons Ltd.)

Baseline CT scans of 116 patients (48% female, median 64 years) with diffuse large B-cell lymphoma (DLBCL) were retrospectively reviewed to investigate the prognostic role of sarcopenia and fat compartment distributions on overall survival (OS), progression-free survival (PFS), and early therapy termination. Skeletal muscle index (SMI), skeletal muscle density (SMD), and intermuscular adipose tissue (IMAT) were quantified at the level of the third lumbar vertebra (L3) and proximal thigh (PT). Low L3-SMD, but not low L3-SMI, was associated with early therapy termination ( p = 0.028), shorter OS (HR = 6.29; 95% CI = 2.17-18.26; p < 0.001), and shorter PFS (HR = 2.42; 95% CI = 1.26-4.65; p = 0.008). After correction for sex, International Prognostic Index (IPI), BMI, and R-CHOP therapy (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone), low L3-SMD remained associated with poor OS (HR = 3.54; 95% CI = 1.10-11.40; p = 0.034) but not with PFS. Increased PT-IMAT was prognostic for poor OS and PFS after correction for sex, IPI, BMI, and R-CHOP therapy (HR = 1.35; CI = 1.03-1.7; p = 0.03, and HR = 1.30; CI = 1.04-1.64; p = 0.024, respectively). Reduced muscle quality (SMD) and increased intermuscular fat (IMAT), rather than low muscle quantity (SMI), are associated with poor prognosis in DLBCL, when measured at the L3 level, and particularly at the level of the proximal thigh. The proximal thigh represents a novel radiological landmark to study body composition., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Besutti, Massaro, Bonelli, Braglia, Casali, Versari, Ligabue, Pattacini, Cavuto, Merlo, Luminari, Merli, Vaccaro and Pellegrini.)

Purpose: To prospectively validate the use of a simplified geriatric assessment (sGA) at diagnosis and to integrate it into a prognostic score for older patients with diffuse large B-cell lymphoma (DLBCL)., Methods: We conducted the prospective Elderly Project study on patients with DLBCL older than 64 years who underwent our Fondazione Italiana Linfomi original geriatric assessment (oGA) (age, Cumulative Illness Rating Scale for Geriatrics, activities of daily living, and instrumental activities of daily living) before treatment. Treatment choice was left to the physician's discretion. The primary end point was overall survival (OS) (ClinicalTrials.gov identifier: NCT02364050)., Results: We analyzed 1,163 patients (median age 76 years), with a 3-year OS of 65% (95% CI, 62 to 68). Because at multivariate analysis on oGA, age > 80 years retained an independent correlation with OS, we also developed a new, simplified version of the GA (sGA) that classifies patients as fit (55%), unfit (28%), and frail (18%) with significantly different 3-year OS of 75%, 58%, and 43%, respectively. The sGA groups, International Prognostic Index, and hemoglobin levels were independent predictors of OS and were used to build the Elderly Prognostic Index (EPI). Three risk groups were identified: low (23%), intermediate (48%), and high (29%), with an estimated 3-year OS of 87% (95% CI, 81 to 91), 69% (95% CI, 63 to 73), and 42% (95% CI, 36 to 49), respectively. The EPI was validated using an independent external series of 328 cases., Conclusion: The Elderly Project validates sGA as an objective tool to assess fitness status and defines the new EPI to predict OS of older patients with DLBCL., Competing Interests: Francesco MerliConsulting or Advisory Role: Janssen, Gilead Sciences, MSD, Takeda, RocheTravel, Accommodations, Expenses: Janssen, Gilead Sciences, EUSA Pharma, Celgene, Roche, Takeda Stefano LuminariConsulting or Advisory Role: Roche, Gilead Sciences, CelgeneTravel, Accommodations, Expenses: Janssen, Celgene Alessandra TucciConsulting or Advisory Role: Janssen, TakedaTravel, Accommodations, Expenses: Sandoz Annalisa ArcariConsulting or Advisory Role: Janssen-CilagTravel, Accommodations, Expenses: Janssen-Cilag, Takeda Luigi RigacciConsulting or Advisory Role: Roche, Gilead Sciences, Takeda, Janssen-Cilag, AbbVie, Celgene/Bristol-Myers Squibb, Merck, MenariniSpeakers' Bureau: Roche, Gilead Sciences, CelgeneTravel, Accommodations, Expenses: Takeda Eliza HawkesConsulting or Advisory Role: Merck Sharpe & Dohme, Roche/Genentech, AstraZeneca, Gilead SciencesSpeakers' Bureau: Roche/GenentechResearch Funding: AstraZeneca, Celgene, Merck KGaA, Janssen-Cilag, Gilead Sciences, Mundipharma, Bristol-Myers SquibbTravel, Accommodations, Expenses: Roche/Genentech Carlos S.

The primary function of 25(OH)Vitamin D (VitD) is to control calcium; however, recent evidence associated serum VitD deficiency to high aggressiveness and worse outcome in different type of malignancies including lymphomas, and the reasons of such effect are to be defined. In this study, we investigated the association of VitD blood levels with gene expression in a retrospective cohort of 181 lymphomas (104 diffuse large B-cell lymphomas [DLBCLs] and 77 classical Hodgkin's lymphomas [cHLs]) of whom 116 with available gene expression profiles (52 DLBCLs and 64 cHLs, respectively). In DLBCL, VitD deficiency did not cause significant alteration in gene expression suggesting different mechanisms of action including a possible systemic effect or an effect on pharmacokinetics. By contrast, in cHLs, VitD deficiency induced profound changes in the transcriptional program leading to the NF-κB-mediated activation of stress-protective and pro-survival pathways. Coherently, VitD signaling defined by vitamin D Receptor (VDR) expression analysis, resulted highly activated in cHLs but not in DLBCLs. Even if preliminary, these data represent the first evidence of a direct role of VitD in the biology of cHL and suggest a multimodality and disease-specific activity of this vitamin in lymphomas., (© 2020 John Wiley & Sons Ltd.)

Mantle cell lymphoma is a rare and incurable lymphoproliferative disorder. In the MCL01 trial, patients were treated with the R-HCVAD regimen [rituximab plus HyperCVAD (hyperfractionated cyclophosphamide, vincristine, doxorubicin, dexamethasone; R-CVAD) alternating with high-dose methotrexate and cytarabine (AM)] for four cycles followed by autologous stem cell transplantation (ASCT) for those who reached only a partial response. After a median follow-up of 10·5 years, we reported 10-year progression-free and overall survival rates of 35% and 61% respectively, with a 10-years cumulative incidence rate of second malignancies of 10·6%. Mature results of the MCL01 trial confirmed the efficacy of HyperCVAD-AM as a frontline regimen for younger patients (≤65 years)., (© 2020 British Society for Haematology and John Wiley & Sons Ltd.)

MCL is an uncommon lymphoproliferative disorder that has been regarded as incurable since its identification as a distinct entity. Allogeneic transplantation for two decades has represented the only option capable of ensuring prolonged remissions and possibly cure. Despite its efficacy, its application has been limited by feasibility limitations and substantial toxicity, particularly in elderly patients. Nevertheless, the experience accumulated over time has been wide though often scattered among retrospective and small prospective studies. In this review, we aimed at critically revise and discuss available evidence on allogeneic transplantation in MCL, trying to put available evidence into the 2020 perspective, characterized by unprecedented development of novel promising therapeutic agents and regimens.

Background: Early palliative care together with standard haematological care for advanced patients is needed worldwide. Little is known about its effect. The aim of the review is to synthesise the evidence on the impact of early palliative care on haematologic cancer patients' quality of life and resource use., Patients and Methods: A systematic review was conducted. The search terms were early palliative care or simultaneous or integrated or concurrent care and haematological or oncohaematological patients. The following databases were searched: PubMed, Embase, Cochrane, CINHAL and Scopus. Additional studies were identified through cross-checking the reference articles. Studies were in the English language, with no restriction for years. Two researchers independently reviewed the titles and abstracts, and one author assessed full articles for eligibility., Results: A total of 296 studies titles were reviewed. Eight articles were included in the synthesis of the results, two controlled studies provided data on the comparative efficacy of PC interventions, and six one-arm studies were included. Since data pooling and meta-analysis were not possible, only a narrative synthesis of the study results was performed. The quality of the two included comparative studies was low overall. The quality of the six non-comparative studies was high overall, without the possibility of linking the observed results to the implemented interventions., Conclusions: Studies on early palliative care and patients with haematological cancer are scarce and have not been prospectively designed. More research on the specific population target, type and timing of palliative care intervention and standardisation of collected outcomes is required., Prospero Registration Number: CRD42020141322., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

We analyzed 160 young Waldenström Macroglobulinemia (WM) patients with a median age of 49 years (range 23-55 years), diagnosed between January 2000 and January 2019 in 14 Italian centers. At diagnosis, 70% of patients were asymptomatic. With a median follow-up of 5.6 years, 57% have been treated. As initial therapy 79% of patients received chemo-immunotherapy, 13% a chemo-free induction and 8% chemotherapy only. At relapse or progression, 6% underwent an autologous stem cell transplantation. Overall, 19% of patients received ibrutinib during the course of the disease. According to IPSSWM, 63% were classified as low risk, 27% as intermediate risk and 10% as high risk. Five-year OS was shorter in high-risk as compared with low or intermediate risk patients (92.9% vs 100% P = .002). According to revised IPSSWM, 92% were classified as very low or low risk and 8% as intermediate risk, with a shorter 5-year OS in the latter group (87.5% vs 100%, P = .028). The OS of young WM patients was not significantly reduced as compared with age-matched, sex-matched and calendar year-matched general population. Early diagnosis, absence of high-risk features in symptomatic patients and high efficacy of modern treatments are the main determinants of the excellent outcome of young WM patients., (© 2020 Wiley Periodicals LLC.)

Introduction: Haematological malignancies often escape the standard information flows of cancer registries because diagnosis is not always based on bone marrow histology but, rather, on other laboratory tests., Objective: To quantify incident haematological malignancies identified exclusively through the laboratory information system and to measure the impact of that source on the sensitivity and accuracy of registering these malignancies., Methods: We collected data from the only provincial laboratory of Reggio Emilia on molecular biology, flow cytometry tests and bone marrow smears to detect specific markers of some chronic haematological malignancies. We carried out a record linkage between laboratory reports (period 2013-2017) of patients resident in the province of Reggio Emilia and the Cancer Registry of Reggio Emilia., Results: Of the 303 patients who underwent at least one of these tests, 85 were not included in our Cancer Registry. Of these 85 patients, 42 had received a diagnosis of cancer: 34 myeloproliferative neoplasms, 3 chronic myeloid leukaemias, 3 myelodysplastic neoplasms, 1 multiple myeloma and 1 chronic lymphocytic leukaemia. We recovered 4.2% of the total number of chronic haemolymphopoietic cancers registered in the study period, accounting for 15% of myeloproliferative neoplasms. For 30% of prelinkage cases, the specificity of the morphological code improved., Conclusions: Although the laboratory information system's contribution to the completeness of Cancer Registry incident cases was modest, it is useful to add laboratory data to routine cancer registry information flows due to the increasing use of molecular characterisation and to the phenomenon of dehospitalisation.

Purpose: Sinusoidal obstruction syndrome (SOS) is one of the most serious complications post haematopoietic stem cell transplantation (HSCT). The diagnosis of SOS is clinical, but nurses should be involved in the pre-transplant risk assessment period and play a crucial role in the early detection of signs and symptoms during and after hospitalization. The aim of this work is to achieve a consensus on nurses' behaviour in caring for SOS., Methods: On behalf of the Italian Group for Bone and Marrow Transplantation (GITMO), a promoter committee was established to put in place a consensus conference approach. A multidisciplinary group of GITMO together with four nurses, three haematology physicians and one patient representative acted as jury, who reviewed the reports and wrote recommendations and suggestions. Recommendations gaining 100% of consensus were considered 'Golden Points of Care'; if a consensus was achieved by ≥ 75% of the jury's members, those recommendations were defined as 'Good Practices'., Results: Eighteen papers written by nurses as first authors have been identified. Golden Points of Care and Good Practices were worked out for the following topics: nurses' role in general, nurses' role in pre-transplant assessment, pre-transplant risk assessment and risk stratification, baseline monitoring, suspected mild or moderate SOS, suspected severe or very severe SOS and late-onset cases., Conclusion: SOS is relatively rare; therefore, a holistic approach to the patients' needs considering nursing role as essential may result in better care outcomes.
