Patients' preferences for chronic lymphocytic leukemia treatment: The CHOICE study.

Chronic lymphocytic leukemia (CLL) therapies differ in efficacy, side effects, route, frequency, and duration of administration. We assessed patient preferences for treatment attributes and evaluated associations with disease stage, treatment line, and socio-demographic characteristics in a cross sectional, observational study conducted at 16 Italian hematology centers. Study visits occurred between February and July 2020; 401 adult patients with CLL (201 Watch and Wait (W&W), 200 treated) participated in a discrete choice experiment (DCE), composed of 8 choices between pairs of treatment profiles with different levels of 5 attributes of currently available CLL treatments (length of response, route and duration of administration, risk of side effects including diarrhea, infections, or organ damage). Health-related quality of life was assessed with the EQ-5D-5L, EORTC QLQ-C30 and QLQ CLL-16. Previously treated patients had longer disease duration (7 vs. 5 years), higher prevalence of serious comorbidities (45.5% vs. 36.2%) and high-risk molecular markers (unmutated IGHV 55.6% vs. 17.1%; TP53 mutation 15.2% vs. 4.0%). Health-related quality of life scores were similar between groups. In the DCE, W&W patients rated "possible occurrence of infections" highest (relative importance [RI] = 36.2%), followed by "treatment and relevant duration" (RI = 28.0%) and "progression-free survival (PFS)" (RI = 16.9%). Previously treated patients rated "treatment and relevant duration" highest (RI = 33.3%), followed by "possible occurrence of infections" (RI = 28.8%), "possible occurrence of organ damage" (RI = 19.4%), and "PFS" (RI = 9.8%). Concern over infection was rated highest overall; unexpectedly PFS was not among the most important criteria in either group, suggesting that the first COVID-19 pandemic wave may have influenced patient preferences and concerns about CLL therapy options.

Health-related Quality of Life Profile of Newly Diagnosed Patients With Myelodysplastic Syndromes by Age, Sex, and Risk Group: A Real-world Study by the GIMEMA.

Health-related quality of life (HRQoL) is an important goal of therapy for patients with myelodysplastic syndromes (MDS); however, little is known about HRQoL of these patients at clinical presentation. We report HRQoL profile of newly diagnosed patients with MDS across both the the International Prognostic Scoring System (IPSS) and IPSS-Revised (IPSS-R) classifications, stratified by sex and age group categories, aiming to also establish European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core30 (EORTC QLQ-C30) reference values for these patients. Analysis was based on 927 patients with a median age of 73.3 years (interquartile range, 66.0-79.2), of whom 506 and 421 with lower- and higher-risk disease respectively, according to the IPSS classification. HRQoL was assessed with the EORTC QLQ-C30 and substantial differences by age groups and sex, between and within lower- and higher-risk disease categories were observed. For example, within higher-risk disease patients, the youngest group (ie, 30-59 years) tended to report clinically meaningful worse outcomes across various functional and symptom domains compared with older age groups. We also developed 2 regression models allowing for the prediction of EORTC QLQ-C30 reference scores for patients classified according to either the IPSS or the IPSS-R. Investigation of prevalence rates for clinically important problems and symptoms at diagnosis revealed a substantial burden of the disease with >50% of patients reporting clinically important problems with physical functioning and dyspnea in both lower- and higher-risk disease. Our findings may help to enhance the interpretation of HRQoL outcomes in future MDS studies and to better contextualize HRQoL data from routine practice settings.

New treatment options in elderly patients with Diffuse Large B-cell Lymphoma.

Most patients with Diffuse Large B-cell Lymphoma (DLBCL) are old (>65 years of age) and this population is expected to increase in the following years. A simplified geriatric assessment based on a careful evaluation of the fitness status and comorbidities is essential to choose the correct intensity of treatment. Fit older patients can benefit from a standard immunochemotherapy, while unfit/frail patients frequently need reduced doses or substitution of particular agents with less toxic ones. This review focuses on new therapies (e.g., polatuzumab vedotin, tafasitamab, bispecific antibodies) that have indicated promising results in relapsed/refractory patients, particularly in cases not eligible to transplant. Some of these new drugs have been tested as single agents or in combinations as first-line treatment, aiming to improve the outcome of the traditional chemotherapy. If preliminary efficacy and safety data are confirmed in future clinical trials, a chemo-free immunotherapic approach could become an alternative option to offer a curative treatment even in frail patients.

A Fondazione Italiana Linfomi cohort study of R-COMP vs R-CHOP in older patients with diffuse large B-cell lymphoma.

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.

Biological features and outcome of diffuse large B-cell lymphoma associated with hepatitis C virus in elderly patients: Results of the prospective 'Elderly Project' by the Fondazione Italiana Linfomi.

Up to 10%-15% of diffuse large B-cell lymphoma (DLBCL) are related to hepatitis C virus (HCV) infection, in particular in elderly patients. The Fondazione Italiana Linfomi has recently published a multicentre prospective observational study, the 'Elderly Project', on the outcome of DLBCL in patients aged ≥65 years, evaluated using a simplified comprehensive geriatric assessment. The aim of this study was to compare biological and clinical features of HCV positive (HCV+) with HCV negative (HCV-) cases. A total of 89 HCV+ patients were identified out of 1095 evaluated for HCV serology (8.1%). The HCV+ patients were older, less fit, and had frequent extranodal involvement. The cell-of-origin determination by Nanostring showed that HCV+ cases less frequently had an activated B-cell profile compared to HCV- patients (18% vs. 43%). In all, 86% of HCV+ patients received rituximab-cyclophosphamide, doxorubicin, vincristine (Oncovin) and prednisone (R-CHOP)-like immunochemotherapy. Grade 3-4 liver toxicity occurred in 3% of cases. Among centrally reviewed cases confirmed as DLBCL, the 3-year overall survival of HCV+ patients was very similar to HCV- (63% vs. 61%, p = 0.926). In all, 20 HCV+ patients were treated with direct-acting antiviral agents (DAAs), with good tolerance and sustained virological response in all cases. The 3-year progression-free survival for this subgroup was excellent (77%), suggesting DAAs' possible role in reducing the risk of relapse by eliminating the viral trigger.

SARS-CoV-2 infection and vaccination in patients with hairy-cell leukaemia.

Little is known of the course of COVID-19 and the antibody response to infection or vaccination in patients with hairy-cell leukaemia (HCL). Among a total of 58 HCL cases we studied in these regards, 37 unvaccinated patients, mostly enjoying a relatively long period free from anti-leukaemic treatment, developed COVID-19 between March 2020 and December 2021 with a usually favourable outcome (fatality rate: 5/37, 14%); however, active leukaemia, older age and more comorbidities were associated with a worse course. Postinfection (n = 11 cases) and postvaccination (n = 28) seroconversion consistently developed, except after recent anti-CD20 or venetoclax therapy, correlating with perivaccine B-cell count. Vaccination appeared to protect from severe COVID-19 in 11 patients with breakthrough infection.

Effective Tumor Debulking with Ibrutinib Before Initiation of Venetoclax: Results from the CAPTIVATE Minimal Residual Disease and Fixed-Duration Cohorts.

PURPOSE: The phase II CAPTIVATE study investigated first-line treatment with ibrutinib plus venetoclax for chronic lymphocytic leukemia in two cohorts: minimal residual disease (MRD)-guided randomized treatment discontinuation (MRD cohort) and fixed duration (FD cohort). We report tumor debulking and tumor lysis syndrome (TLS) risk category reduction with three cycles of single-agent ibrutinib lead-in before initiation of venetoclax using pooled data from the MRD and FD cohorts. PATIENTS AND METHODS: In both cohorts, patients initially received three cycles of ibrutinib 420 mg/day then 12 cycles of ibrutinib plus venetoclax (5-week ramp-up to 400 mg/day). RESULTS: In the total population (N = 323), the following decreases from baseline to after ibrutinib lead-in were observed: percentage of patients with a lymph node diameter ≥5 cm decreased from 31% to 4%, with absolute lymphocyte count ≥25 × 109/L from 76% to 65%, with high tumor burden category for TLS risk from 23% to 2%, and with an indication for hospitalization (high TLS risk, or medium TLS risk and creatinine clearance <80 mL/minute) from 43% to 18%. Laboratory TLS per Howard criteria occurred in one patient; no clinical TLS was observed. CONCLUSIONS: Three cycles of ibrutinib lead-in before venetoclax initiation provides effective tumor debulking, decreases the TLS risk category and reduces the need for hospitalization for intensive monitoring for TLS.

Direct-Acting Antivirals as Primary Treatment for Hepatitis C Virus-Associated Indolent Non-Hodgkin Lymphomas: The BArT Study of the Fondazione Italiana Linfomi.

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_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.

COVID-19, inflammatory response, iron homeostasis and toxicity: a prospective cohort study in the Emergency Department of Piacenza (Italy).

BACKGROUND AND AIM: Dysregulation of iron metabolism and hyper-inflammation are two key points in the pathogenesis of coronavirus disease 2019 (COVID-19). Since high hepcidin levels and low serum iron can predict COVID-19 severity and mortality, we decided to investigate iron metabolism and inflammatory response in 32 COVID-19 adult patients with a diagnosis of COVID-19 defined by a positive result of RT-PCR nasopharyngeal swab, and admitted to an Italian emergency department for acute respiratory failure at different degree. METHODS: Patients were stratified in 3 groups based on PaO2/FiO2 ratio at admission: 13 (41%) were normoxemic at rest and suffered from exertional dyspnea (group 1); 14 (44%) had a mild respiratory failure (group 2), and 5 (15%) a severe hypoxiemia (group 3). RESULTS: White blood cells were significantly higher in group 3, while lymphocytes and hemoglobin were significantly reduced. Serum iron, transferrin saturation, non-transferrin-bound iron (NTBI) and ferritin were significantly increased in group 2. All the groups showed high hepcidin levels, but in group 3 this parameter was significantly altered. It is noteworthy that in group 1 inflammatory and oxidative indices were both within the normal range. CONCLUSIONS: We are aware that our study has some limitations, the small number of enrolled patients and the short period of data collection, but few works have been performed in the Emergency Room. However, we strongly believe that our results confirm the pivotal role of both iron metabolism dysregulation and hyper-inflammatory response in the pathogenesis of tissue and organ damage in COVID-19 patients.

Myeloablative conditioning with thiotepa-busulfan-fludarabine does not improve the outcome of patients transplanted with active leukemia: final results of the GITMO prospective trial GANDALF-01.

The outcome of refractory/relapsed (R/R) acute leukemias is still dismal and their treatment represents an unmet clinical need. However, allogeneic transplantation (allo-HSCT) remains the only potentially curative approach in this setting. A prospective study (GANDALF-01, NCT01814488; EUDRACT:2012-004008-37) on transplantation with alternative donors had been run by GITMO using a homogeneous myeloablative conditioning regimen with busulfan, thiotepa and fludarabine while GVHD prophylaxis was stratified by donor type. The study enrolled 101 patients; 90 found an alternative donor and 87 ultimately underwent allo-HSCT. Two-year overall survival of the entire and of the transplant population (primary endpoint) were 19% and 22%, without significant differences according to disease, donor type and disease history (relapsed vs refractory patients). Two-year progression-free survival was 19% and 17% respectively. The cumulative incidences of relapse and non-relapse mortality were 49% and 33% at two years. Acute grade II-IV and chronic GVHD occurred in 23 and 10 patients. Dose intensification with a myeloablative two-alkylating regimen as sole strategy for transplanting R/R acute leukemia does seem neither to improve the outcome nor to control disease relapse. A pre-planned relapse prevention should be included in the transplant strategy in this patient population.

Mixed T cell CHIMERISM in bone marrow at day+30 after allogeneic stem cell transplantation: Correlation with acute GVHD grades III-IV and no impact on relapse and overall survival.

OBJECTIVES: Early chimerism analysis is important to assess engraftment in allogeneic hematopoietic stem cell transplantations. METHODS: We retrospectively investigated the impact of T-cell chimerism at day 30 in bone marrow on acute graft-versus-host disease (aGVHD), relapse, and overall survival in 142 adult allo-transplanted patients. RESULTS: The majority of patients (89%) received myeloablative conditioning and 90% have undergone T-cell replete donor graft. At day 30, 103 patients showed T-complete chimerism with prevalence in haploidentical transplants, whereas 39 cases had CD3+ mixed chimerism, including 30 patients transplanted with HLA identical donors, and 21 with T-cell donors<90%. T-cell chimerism at day 30 was weakly inversely related to aGVHD grades II-IV (p = .078) with no cases of grades III-IV aGVHD in patients with CD3+ <95%. Mixed T-cell chimerism did not impact on relapse (p = .448) and five of the seven patients who relapsed had T-cell chimerism ≤90%. Older age and active disease at transplant had a statistically significant negative effect on overall survival (p = .01 and p = .0001, respectively), whereas mixed CD3+ chimerism did not. CONCLUSIONS: T lymphocyte chimerism analysis at day +30 in bone marrow could identify allo-transplanted patients at major risk of aGVHD grades III-IV (CD3+ donors >95%) mainly post-myeloablative conditioning regimen.

A prognostic model for patients with lymphoma and COVID-19: a multicentre cohort study.

Lymphoma represents a heterogeneous hematological malignancy (HM), which is characterized by severe immunosuppression. Patients diagnosed of coronavirus disease 2019 (COVID-19) during the course of HM have been described to have poor outcome, with only few reports specifically addressing lymphoma patients. Here, we investigated the clinical behavior and clinical parameters of a large multicenter cohort of adult patients with different lymphoma subtypes, with the aim of identifying predictors of death. The study included 856 patients, of whom 619 were enrolled prospectively in a 1-year frame and were followed-up for a median of 66 days (range 1-395). Patients were managed as outpatient (not-admitted cohort, n = 388) or required hospitalization (n = 468), and median age was 63 years (range 19-94). Overall, the 30- and 100-days mortality was 13% (95% confidence interval (CI), 11% to 15%) and 23% (95% CI, 20% to 27%), respectively. Antilymphoma treatment, including anti-CD20 containing regimens, did not impact survival. Patients with Hodgkin's lymphoma had the more favorable survival, but this was partly related to significantly younger age. The time interval between lymphoma diagnosis and COVID-19 was inversely related to mortality. Multivariable analysis recognized 4 easy-to-use factors (age, gender, lymphocyte, and platelet count) that were associated with risk of death, both in the admitted and in the not-admitted cohort (HR 3.79 and 8.85 for the intermediate- and high-risk group, respectively). Overall, our study shows that patients should not be deprived of the best available treatment of their underlying disease and indicates which patients are at higher risk of death. This study was registered with ClinicalTrials.gov, NCT04352556.

[Territorial-based management of patients with cancer on active treatment following the Piacenza (north Italy) Model. Results of 4 consecutive years.] / Le cure oncologiche ed ematologiche sul territorio secondo il modello dell'ASL di Piacenza. Rendiconto di 4 anni consecutivi.

INTRODUCTION: The natural history of cancer has radically changed in the last decade. The burden of travel from patient's residence to health care providers is an important issue that can influence access to diagnosis and treatment of cancer; however this issue is quite neglect by the medical community and by the national health system. In addition, community care in the oncology field is actually debated. METHODS: In the district of Piacenza an innovative model to deliver onco-hematologic treatment near the residence of patients was initiated some years ago. The oncologic and hematologic treatments are delivered by specialized nurses under supervision of medical oncologists or hematologists at the 3 community hospital and at 1 house of health in the district of Piacenza. We conducted a retrospective study involving 1,339 cancer patients (CPs) managed and treated near their residence, CPs were on active medical treatment at the oncology and hematology department Azienda sanitaria (ASL) of Piacenza (North Italy). The electronic data base of the antiblastic drug unit (UFA) of the ASL Piacenza, provided: the number of patients treated each year, number of treatments and the accesses to the territorial medical structure each year. The kms saved to reach the nearest territorial structures instead of the oncologic unit of the city hospital, were registered and recorded. RESULTS: During a 4 years period, from January 2017 to December 2020, 1,339 CPs were treated near their residence, 278 in the year 2017, 347 in 2018, 354 in 2019 and 360 in 2020. The total accesses for treatment in 4 years were 10,003: 2,214 in the year 2017, 2,652 in 2018, 2,524 in 2019 and 2,613 in 2020. The mean distance saved for each patient was 937 kms in the year 2017, 891 in 2018, 879 in 2019, 920 in 2020, totally a mean of 3,627 kms in the 4 years. DISCUSSION AND CONCLUSION: We believe that the results of our retrospective study highlight the possibility of treating cancer patients in territorial structures near their residence, with advantages for patients themselves, their caregivers and for the entire community.

COVID-19 vaccines in adult cancer patients with solid tumours undergoing active treatment: Seropositivity and safety. A prospective observational study in Italy.

INTRODUCTION: Patients with cancer are presumed a frail group at high risk of contracting coronavirus disease (COVID-19), and vaccination represents a cornerstone in addressing the COVID-19 pandemic. However, data on COVID-19 vaccination in cancer patients are fragmentary and poor. METHODS: An observational study was conducted to evaluate the seropositivity rate and safety of a two-dose regimen of the BNT162b2 or messenger RNA-1273 vaccine in adult patients with solid cancer undergoing active anticancer treatment or whose treatment had been terminated within 6 months of the start of the study. The control group was composed of healthy volunteers. Serum samples were evaluated for SARS-COV-2 antibodies before vaccinations and 2-6 weeks after the administration of the second vaccine dose. Primary end-point: seropositivity rate. Secondary end-points: safety, factors influencing seroconversion, IgG titers of patients versus healthy volunteers, COVID-19 infection. RESULTS: Between 20th March 2021 and 12th June 2021, 293 consecutive patients with cancer-solid tumours underwent a program of COVID-19 vaccinations; of these, 2 patients refused vaccination, 13 patients did not receive the second dose of the vaccine because of cancer progression, and 21 patients had COVID-19 antibodies at baseline and were excluded. The 257 evaluable patients had a median age of 65 years (range 28-86), 66.15% with metastatic disease. Primary end-point: seropositivity rate in patients was 75.88% versus 100% in the control group. Secondary end-points: no Grade 3-4 side-effects, no COVID-19 infections were reported. Patients median IgG titer was significantly lower than in the control group; male sex and active anticancer therapy influenced negative seroconversion. BNT162b2 or messenger RNA-1273 vaccines were immunogenic in cancer patients, showing good safety profile.

Allogeneic stem cell transplantation in patients with mantle cell lymphoma: results from the MANTLE-FIRST study on behalf of Fondazione Italiana Linfomi.

The role of allogeneic stem cell transplantation (allo-SCT) in mantle cell lymphoma (MCL) is uncertain, even more in the era of bruton's tyrosine kinase inhibitors (BTKi) and chimeric antigen receptor T-cells. We retrospectively analyzed 55 patients who underwent allo-SCT for MCL relapsed or refractory (r/r) after rituximab and high-dose cytarabine within the MANTLE-FIRST project. With a median follow-up of 3.7 years, non-relapse mortality (NRM), progression-free survival, and overall survival were 23%, 53%, and 56%, respectively. NRM was significantly higher in the case of acute graft-versus-host disease, > 2 prior lines of therapy, age > 60 years. The outcome was similar for patients with early (≤24 months) and late progression of disease. The use of BTKi as a bridge to allo-SCT did not increase the toxicity and allowed a good control of disease. Our real-life experience confirms that allo-SCT still represents an option in MCL patients, especially if young and early-relapsed.

COVID-19 and stem cell transplantation; results from an EBMT and GETH multicenter prospective survey.

This study reports on 382 COVID-19 patients having undergone allogeneic (n = 236) or autologous (n = 146) hematopoietic cell transplantation (HCT) reported to the European Society for Blood and Marrow Transplantation (EBMT) or to the Spanish Group of Hematopoietic Stem Cell Transplantation (GETH). The median age was 54.1 years (1.0-80.3) for allogeneic, and 60.6 years (7.7-81.6) for autologous HCT patients. The median time from HCT to COVID-19 was 15.8 months (0.2-292.7) in allogeneic and 24.6 months (-0.9 to 350.3) in autologous recipients. 83.5% developed lower respiratory tract disease and 22.5% were admitted to an ICU. Overall survival at 6 weeks from diagnosis was 77.9% and 72.1% in allogeneic and autologous recipients, respectively. Children had a survival of 93.4%. In multivariate analysis, older age (p = 0.02), need for ICU (p < 0.0001) and moderate/high immunodeficiency index (p = 0.04) increased the risk while better performance status (p = 0.001) decreased the risk for mortality. Other factors such as underlying diagnosis, time from HCT, GVHD, or ongoing immunosuppression did not significantly impact overall survival. We conclude that HCT patients are at high risk of developing LRTD, require admission to ICU, and have increased mortality in COVID-19.

A Clinical Prognostic Model Based on Machine Learning from the Fondazione Italiana Linfomi (FIL) MCL0208 Phase III Trial.

BACKGROUND: Multicenter clinical trials are producing growing amounts of clinical data. Machine Learning (ML) might facilitate the discovery of novel tools for prognostication and disease-stratification. Taking advantage of a systematic collection of multiple variables, we developed a model derived from data collected on 300 patients with mantle cell lymphoma (MCL) from the Fondazione Italiana Linfomi-MCL0208 phase III trial (NCT02354313). METHODS: We developed a score with a clustering algorithm applied to clinical variables. The candidate score was correlated to overall survival (OS) and validated in two independent data series from the European MCL Network (NCT00209222, NCT00209209); Results: Three groups of patients were significantly discriminated: Low, Intermediate (Int), and High risk (High). Seven discriminants were identified by a feature reduction approach: albumin, Ki-67, lactate dehydrogenase, lymphocytes, platelets, bone marrow infiltration, and B-symptoms. Accordingly, patients in the Int and High groups had shorter OS rates than those in the Low and Int groups, respectively (Int→Low, HR: 3.1, 95% CI: 1.0-9.6; High→Int, HR: 2.3, 95% CI: 1.5-4.7). Based on the 7 markers, we defined the engineered MCL international prognostic index (eMIPI), which was validated and confirmed in two independent cohorts; Conclusions: We developed and validated a ML-based prognostic model for MCL. Even when currently limited to baseline predictors, our approach has high scalability potential.

Haploidentical related donor compared to HLA-identical donor transplantation for chemosensitive Hodgkin lymphoma patients.

BACKGROUND: Allogeneic stem cell transplantation from haploidentical donor using an unmanipulated graft and post-transplantation cyclophosphamide (PT-Cy) is growing. Haploidentical transplantation with PT-Cy showed a major activity in Hodgkin lymphoma (HL), reducing the relapse incidence. The most important predictive factor of survival and toxicity was disease status before transplantation, which was better in patients with well controlled disease. METHODS: We included 198 HL in complete (CR) or partial remission (PR) before transplantation. Sixty-five patients were transplanted from haploidentical donor and 133 from a HLA identical donor (both sibling and unrelated donors). Survival analysis was defined according to the EBMT criteria. Survival curves were generated by using Kaplan-Meier method and differences between groups were compared by the log rank test or by the log rank test for trend when appropriated. RESULTS: The PFS, OS, and RI were significantly better in patients in CR compared to PR (55% vs 29% p = 0.001, 74% vs 55% p = 0.03, 27% vs 55% p <  0.001, respectively). The 2-year PFS was significantly better for HAPLO than HLA-id (63% vs 37%, p = 0.03), without difference in OS. The 1-year NRM was not different. The 2-year relapse incidence (RI) was lower in the HAPLO group (24% vs 44%, p = 0.008). Patients in CR receiving haplo HSCT showed higher 2-year PFS and lower 2-year RI than those allografted with HLA-id donor (75% vs 47%, p <  0.001 and 11% vs 34%, p < 0.001, respectively). In multivariate analysis, donor type and disease status before transplantation were independent predictors of PFS as well as they predict the risk of relapse. Disease status at transplantation and age were independently associated to OS. CONCLUSIONS: Nonetheless this is a retrospective study, limiting the wide applicability of results, data from this analysis suggest that HLA mismatch can induce a strong graft versus lymphoma effect leading to an enhanced PFS.

Iron overload and Hepcidin overexpression could play a key role in COVID infection, and may explain vulnerability in elderly, diabetics, and obese patients.

BACKGROUND: The COVID epidemic hit like a tsunami worldwide. At the time of its arrival in Italy, available literary data were meager, and most of them concerned its epidemiology. World Health Organization proposed guidelines in march 2020, a strategy of treatment has been developed, and a significant number of subsequent articles have been published to understand, prevent, and cure COVID patients. METHODS: From the observation of two patients, we performed a careful analysis of scientific literature to unearth the relation between COVID infection, clinical manifestations as pneumonia and thrombosis, and to find out why it frequently affects obese, diabetics, and elderly patients. RESULTS: The analysis shows that hepcidin could represent one of such correlating factors. Hepcidin is most elevated in older age, in non-insulin diabetics patients and in obese people. It is the final target therapy of many medicaments frequently used. Viral disease, and in particular SARS-CoV19, could induce activation of the hepcidin pathway, which in turn is responsible for an increase in the iron load. Excess of iron can lead to cell death by ferroptosis and release into the bloodstream, such as free iron, which in turn has toxic and pro-coagulative effects. CONCLUSIONS: Overexpression of hepcidin and iron overload might play a crucial role in COVID infection, becoming potential targets for treatment. Hepcidin could also be considered as a biomarker to measure the effectiveness of our treatments and the restoration of iron homeostasis the final intent. (www.actabiomedica.it).
