With climate, biodiversity and inequity crises squarely upon us, never has there been a more pressing time to rethink how we conceptualize, understand and manage our relationship with Earth's biodiversity. Here, we describe governance principles of 17 Indigenous Nations from the Northwest Coast of North America used to understand and steward relationships among all components of nature, including humans. We then chart the colonial origins of biodiversity science and use the complex case of sea otter recovery to illuminate how ancestral governance principles can be mobilized to characterize, manage and restore biodiversity in more inclusive, integrative and equitable ways. To enhance environmental sustainability, resilience and social justice amid today's crises, we need to broaden who benefits from and participates in the sciences of biodiversity by expanding the values and methodologies that shape such initiatives. In practice, biodiversity conservation and natural resource management need to shift from centralized, siloed approaches to those that can accommodate plurality in values, objectives, governance systems, legal traditions and ways of knowing. In doing so, developing solutions to our planetary crises becomes a shared responsibility. This article is part of the theme issue ‘Detecting and attributing the causes of biodiversity change: needs, gaps and solutions’.

Novel drugs are rapidly moving forward the treatment-paradigm of non-Hodgkin-lymphomas (NHLs). Notwithstanding, especially in aggressive subtypes, chemotherapy remains the pillar of treatment. Indeed, the combination of highly effective Maximum-Tolerated-Dose Chemotherapy (MTD-CHEMO) + “novel drugs”, has so far, fallen short from expectations, often because it caused excessive toxicity. Metronomic chemotherapy (mCHEMO), which is the frequent, long-term administration of low dose cytotoxic drugs, may allow more effective and tolerable combinations. mCHEMO pharmacodynamics, has been described as pleiotropic. In fact, it may have different cellular and molecular targets, when drugs or their schedules are modified. Although mCHEMO has been little explored in NHLs, pre-clinical studies - in lymphoma models - which addressed the activity of mCHEMO in combination with novel drugs, have shown very promising results. These included inhibitors of histone deacetylase, mTOR and PI3K/mTOR, as well as the immune checkpoint inhibitor anti-PD-L1. Moreover, a few impressive reports have recently shown all-oral mCHEMO schedules, with or without rituximab, can effectively shrink both B and T-cell aggressive NHLs. Indeed, these regimens allowed elderly-frail patients to achieve sustained remission, while toxicity proved manageable. In our opinion, all-oral mCHEMO, is an active, easy-to start, well-tolerated, and inexpensive therapeutic approach, which deserves further investigation. Most importantly, mCHEMO, holds promise to empower the activity of novel targeted therapies, without causing excessive toxicity.

Purpose:This study was aimed at evaluating the feasibility, safety, immunologic and clinical responses in patients with follicular lymphoma treated with monocyte-derived dendritic cells generated in the presence of IFNα and GM-CSF (IFN-DC) in combination with low doses of rituximab.Patients and Methods:Firstly, we analyzed in vitro and in vivo the immunologic properties of IFN-DC against follicular lymphoma. Thus, we performed a phase I trial in 8 patients with refractory and relapsed follicular lymphoma based on sequential intranodal injections of low-dose of rituximab and unloaded IFN-DC and report the safety, clinical, and immunologic results of the enrolled patients.Results:Preclinical studies indicated that IFN-DC can synergize with rituximab leading to increased cytotoxicity and T-cell tumor infiltration. The clinical evaluation showed that the combined treatment was totally safe. The overall response rate was 50%, PET-negative complete response rate 37%, and remission is still ongoing in 2/4 of responding patients (median follow-up 26 months, range 11–47). Notably, following the combined therapy all patients showed induction/enhancement of T-cell responses by CD107 degranulation or IFNγ ELISPOT assay against patient-specific tumor IGHV sequences.Conclusions:These results represent the proof-of-principle on the effectiveness of unloaded IFN-DC in inducing durable clinical responses and promoting induction of tumor-specific peripheral T cells, thus suggesting the occurrence of an effective endogenous antitumor vaccination. The overall findings indicate that some unique properties of IFN-DC can be successfully exploited to induce/enhance antitumor responses, thus representing a valuable antitumor strategy for novel and more effective combination therapies in patients with cancer.

The upfront treatment of very elderly and frail patients with diffuse large B-cell lymphoma (DLBCL) is still a matter of debate. Herein, we report results of the metronomic all-oral DEVEC [prednisolone/deltacortene®, vinorelbine (VNR), etoposide (ETO), cyclophosphamide] combined with i.v. rituximab (R). This schedule was administered as a first line therapy in 22 elderly/frail DLBCL subjects (median age = 84.5 years). In 17/22 (77%) patients, the Elderly-IPI-score was high. After a median follow-up of 24 months, 15 patients had died: seven (50%) for causes unrelated to DLBCL or its treatment, six (40%) for progression, and two (13%) for multiorgan failure. Six treatment-pertinent serious-adverse-events occurred. At the end of induction, 14/22 (64%) achieved complete remission; overall survival and event-free survival at 24 months were both 54% (95% CI = 32–72%), while the time to progression was 74% (95% CI = 48–88%). Furthermore, antiproliferative and proapoptotic assays were performed on DLBCL/OCI-LY3 cell-line using metronomic VNR and ETO and their combination. Both metronomic VNR and ETO had concentration-dependent antiproliferative (IC50 = 0.036 ± 0.01 nM and 7.9 ± 3.6 nM, respectively), and proapoptotic activities in DLBCL cells. Co-administration of the two drugs showed a strong synergism (combination index < 1 and dose reduction index > 1) against cell proliferation and survival. This low-dose schedule seems to compare favourably with intravenous-CHEMO protocols used in the same subset. Indeed, the high synergism shown by metronomic VRN+ETO in in vitro studies, explains the remarkable clinical responses and it allows significant dose reductions.

Purpose Peripheral T cell lymphomas (PTCLs) have an overall poor prognosis. Indeed, registry data in elderly patients show that the median progression-free survival (mPFS) following first- and second-line therapies are only 6.7 and 3.1 months, respectively. The aim of the study is to show the activity of metronomic chemotherapy, a regular administration of low chemotherapeutic drug doses allowing a favourable toxicity profile, on elderly PTCL patients. Methods We report a series of 17 PTCL patients, treated with the all-oral metronomic schedule DEVEC (prednisolone–etoposide–vinorelbine–cyclophosphamide) in four Italian centres. Patients 5/17 (29.4%) were treatment-naïve (naïve) and 12/17 (70.6%) were relapsed-refractory (RR), respectively. The median age was 83 years (range 71–87) and 71.5 years (range 56–85) for naïve and RR, respectively. In vitro activity of metronomic vinorelbine (VNR), etoposide (ETO) and their concomitant combination on HH, a PTCL cell line, was also assessed. Results Histology: PTCL-not-otherwise-specified = 12; angioimmunoblastic = 2; NK/T nasal type = 1; adult-type leukaemia lymphoma = 1, transformed Mycosis Fungoides = 1. The overall response rate was 80 and 58% in naïve and RR, respectively; whereas the PFS was 20 in naïve (95% CI 0–43) and 11 months (95% CI 4.2–17.8) in RR. The occurrence of relevant adverse events was 23.5%, which was managed with ETO dose reduction. In vitro experiments showed that both metronomic VNR and ETO caused a significant inhibitory activity on HH cells and a strong synergism when administered concomitantly. Conclusion All-oral DEVEC showed an encouraging activity and acceptable toxicity. This schedule deserves further studies in elderly PTCL also for assessing combinations with targeted drugs.

Doxorubicin is the most effective single agent in the treatment of non‐Hodgkin's lymphoma (NHL). Its use is limited because of the cardiac toxicity primarily in elderly patients (pts) and in pts with history of cardiac disease. Liposomal doxorubicin has been proven to reduce cardiotoxicity. The aim of this retrospective study was the use of nonpeghylated liposomal doxorubicin (NPLD) in term of efficacy, response rate and incidence of cardiac events. We retrospectively collected the experience of 33 Hematological Italian Centers in using NPLD. Nine hundred and forty‐six consecutive pts treated with R‐COMP (doxorubicin was substituted with NPLD, Myocet) were collected. Median age was 74 years, the reasons for use of NPLD were: age (466 pts), cardiac disease (298 pts), uncontrolled hypertension (126 pts), other reasons (56 pts). According to clinicians' evaluation, 49.9% of pts would not have used standard doxorubicin for different situations (age, cardiomyopathy, previous use of doxorubicin, and uncontrolled hypertension). Overall 687 pts (72.6%) obtained a complete remission (CR). About 5% (n = 51) of subjects developed major cardiotoxic events including heart failure (N = 31), ischemic heart disease (N = 16), acute heart attack (N = 3), and acute pulmonary oedema (N = 1). After a median follow‐up of 32 months, 651 pts were alive and the overall survival (OS) was 72%. After a median observation period of 23 months disease free survival (DFS) was 58%. Either in univariate or in multivariate analysis OS and DFS were not significantly affected by age or cardiac disease. Our findings strongly support that including R‐COMP is effective and safe when the population is at high risk of cardiac events and negatively selected. Moreover, the use of this NPLD permitted that about half of our population had the opportunity to receive the best available treatment.

PURPOUSE: to assess the clinicopathologic features of a poorly defined subset of diffuse large b-cell lymphoma, which is characterized by the secretion of an IgM paraprotein (IgMs-DLBCL). EXPERIMENTAL DESIGN: multicentre, retrospective, and comparative study to analyse with an integrated diagnostic approach the IgMs-DLBCL subset.RESULTS: Overall, 650 DLBCL were enrolled: 102 had an associated serum IgM and 56 other paraproteins (OP), the remaining 492 cases were the reference group (REF). IgMs-DLBCL were characterized by older age, advanced stage, dissemination to extra-nodal organs, elevated LDH and poor PS. As a result, the majority of IgMs had a high IPI, NCC-IPI and CNS-IPI score (p

Peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS) is the most common entity of mature T-cell neoplasms. PTCL-NOS generally has an aggressive behavior and is often refractory to standard therapy. Only a few cases of PTCL with aberrant expression of B-cell antigens have been reported so far. This phenotypic aberrancy may lead to misdiagnosis as B-cell non-Hodgkin lymphomas and eventual inappropriate patient management, whereas in an accurately diagnosed PTCL, the presence of CD20 may appear as an appealing therapeutic target. In this setting, response to anti-CD20 monoclonal antibody in combination with chemotherapy has been poorly explored. We describe the case of a 59-year-old male diagnosed by a pathological and molecular approach as PTCL-NOS with aberrant co-expression of the B-cell antigens CD20 and CD79a, which proved non-responsive to the addition of rituximab to standard polychemotherapy. This case highlights that the presence of CD20 in PTCL may be misleading in the diagnosis and also act as a lure for the clinician to adopt a rituximab-based treatment, the effectiveness of which is undefined as the molecular mechanisms underlying B-cell marker expression in PTCL.

Patients with mantle cell lymphoma (MCL) that fail induction treatment represent a difficult-to-treat population, where no standard therapy exists. We evaluated outcomes in patients with first relapsed-refractory (r/r) MCL after upfront high dose cytarabine including standard regimens. Overall survival (OS-2) and progression-free survival (PFS-2) were estimated from the time of salvage therapy. The previously described threshold of 24 months was used to define patients as early- or late-progressors (POD). Overall, 261 r/r MCL patients were included. Second-line regimens consisted of rituximab-bendamustine (R-B, 21%), R-B and cytarabine (R-BAC, 29%), ibrutinib (19%), and others (31%). The four groups were balanced in terms of clinicopathological features. Adjusting for age and early/late-POD, patients treated with R-BAC had significantly higher complete remission (63%) than comparators. Overall, Ibrutinib and R-BAC were associated with improved median PFS-2 [24 and 25 months, respectively], compared to R-B (13) or others (7). In patients with early-POD (n = 127), ibrutinib was associated with inferior risk of death than comparators (HR 2.41 for R-B, 2.17 for others, 2.78 for R-BAC). In patients with late-POD (n = 134), no significant differences were observed between ibrutinib and bendamustine-based treatments. Ibrutinib was associated with improved outcome in early-POD patients.

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.

Follicular lymphoma (FL) is a remarkably immune-responsive malignancy, which is still considered incurable. As, standard immunochemotherapy is complex, toxic and not curative, improvement in FL care is now a crucial topic in hemato-oncology. Recently, we and others have shown that dendritic cell (DC)-based therapies allow a specific immune response associated with sustained lymphoma regression in a proportion of low-tumor burden FL patients. Importantly, the rate of objective clinical response (33-50%) and of sustained remission is remarkably higher compared to similar studies in solid tumors, corroborating the assumption of the immune responsiveness of FL. Our experimental intra-tumoral strategy combined injection with rituximab and interferon-α-derived dendritic cells (IFN-DC), a novel DC population particularly efficient in biasing T-helper response toward the Th1 type and in the cross-priming of CD8 + T cells. Noteworthy, intra-tumoral injection of DC is a new therapeutic option based on the assumption that following the induction of cancer-cell immunogenic death, unloaded DC would phagocytize in vivo the tumor associated antigens and give rise to a specific immune response. This approach allows the design of easy and inexpensive schedules. On the other hand, advanced and straightforward methods to produce clinical-grade antigenic formulations are currently under development. Both unloaded DC strategies and DC-vaccines are suited for combination with radiotherapy, immune checkpoint inhibitors, immunomodulators and metronomic chemotherapy. In fact, studies in animal models have already shown impressive results, while early-phase combination trials are ongoing. Here, we summarize the recent advances and the future perspectives of DC-based therapies in the treatment of FL patients.

Lymphoma treatments can produce adverse effects leading to a reduced quality-of-life (QoL). Besides, in patients ≥65years, it can promote an accelerated geriatric decay. We conducted a prospective study on supervised Exercise-Training (ET), in consecutive, patients aged 18-80years, during anti-lymphoma treatments.16/30 (53%), median-age = 65.5y, participated to the ET sessions, this was the Interventional Group (IG); 14/30 (47%), median-age = 63y, were the Reference Group (RG). Both groups participated to the fitness and the QoL assessments, at baseline (T0), 3-months (T1) and 6-months (T2) after the start of chemotherapy. The adherence to the ET program was 50% (95% CI:36-64%). The IG showed substantial improvements compared to the CG in cardiorespiratory fitness (Cooper test) at both T1 and T2 and in all the functional domain of the QoL questionnaire (QLQ-C30) at T2. This study showed ET, during chemotherapy, is feasible and safe, even in patients ≥65 years. Furthermore, it may improve the provision of care.

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

Aim To evaluate the efficacy of residual site radiation therapy (RSRT) on local control (LC), progression-free (PFS) and overall (OS) survival in patients with primary mediastinal lymphoma (PMBCL), following rituximab and chemotherapy treatment (ICHT). Patients and methods The study included 34 patients with PMBCL treated between 2006 and 2014 with ICHT with/without autologous stem cell transplantation and RSRT. Between the end of ICHT/stem cell transplantation and RSRT, patients were evaluated with 18F-fluorodeoxyglucose positron-emission tomography. The gross tumor volume included morphological mediastinal residual disease after ICHT/SCT. The percentage of LC, PFS and OS were assessed. Results All patients received RSRT with a median dose of 30 Gy. Median follow-up was 82 months. One patient out of 34 (3%) showed progressive disease 9 months from diagnosis. The 10-year PFS and OS were 97% and 97% respectively. Conclusion RSRT in patients with PMBCL treated with ICHT did not impact unfavorably on LC and patient survival.

The Garcin syndrome is a rare condition characterized by multiple unilateral cranial nerve palsy, without neither long-tract involvement nor intracranial hypertension. Non-Hodgkin lymphoma is a systemic malignant disease that localizes in a minority of cases in the central nervous system. We report a case of Garcin syndrome that revealed a diffuse large B cell lymphoma (DLBCL) located in the skull base and in the right kidney. We reached the diagnosis by mean of a nonstandard, mini-invasive, transforamen ovale biopsy of the intracranial lesion (Hartel's route).The nature of the renal mass was determined ex juvantibus. The patient responded to the polichemotherapy with a complete regression of the intracranial lesion and of the renal mass evaluated by computed tomography and total body positron emission tomography scans. We, therefore, confirmed the DLBCL location in the right kidney. Over 4 years of follow-up, the patient has showed a complete remission of the disease. In this report, we emphasize the importance of biopsy in case of Garcin syndrome.

Introduction: We recently demonstrated in a large multicentre study that sGA can identify fit older patients with aggressive lymphoma able to tolerate first-line intensive treatment with curative intent and to obtain similar results than younger people (Merli at al JCO 2021). Regardless of age, about 40% of patients with aggressive lymphoma are either refractory or will eventually relapse after treatment with curative intent. Salvage platinum-based regimens followed by ASCT in responsive disease is a standard of care to obtain longer second remission. However, in many case series, patients over 65 years are excluded from the transplant approach because of potential severe toxicities of high-dose therapy in older patients. This study was designed to evaluate the feasibility and activity of high-dose treatment followed by ASCT in older FIT patients with R/R aggressive lymphoma selected with a sGA. Methods: Patients with R/R aggressive lymphoma after one line of treatment, aged between 65 and 75, and FIT to sGA were eligible for the study. Salvage treatment could be chosen between R-DHAP, R-ICE or other platinum or gemcitabine-containing regimens and stem cells were mobilized after 1 or 2 cycles. Patients achieving at least partial response after 3 courses and who remained FIT to sGA evaluation were eligible for ASCT and were conditioned with either BEAM or FEAM. Results: From May 2014 to August 2019, seventy-five patients from 16 FIL centres were enrolled and 70 were eligible for the study. Sixty-six of them had a diffuse large B-cell lymphoma, one had follicular 3b, 2 mantle cell and 1 Burkitt histology. Salvage treatment was R-DHAP in 48 patients, R-ICE in seven and gemcitabine or oxalyplatinum containing regimens in the remaining ones. Overall response rate after three courses was 44% (21 complete and 10 partial remission). Among the 39 unresponsive patients, 29 had progressive and 4 stable disease, 2 patients died of septic shock and heart failure during salvage and 4 patients withdrew their consent to ASCT. Four patients relapsed soon after response achievement before undergoing the transplant. ASCT was performed in 27 patients with a median of 5.6 x 10 6 CD34/Kg reinfused. No differences emerged in demographic and clinical characteristics between patients reaching the ASCT timepoint or not (Tab 1a). By intention to treat analysis, 2-y overall survival (OS) and PFS of the entire intention-to-treat population were 65% (95%CI: 50-76%) and 34% (95%CI: 22-46%) respectively, without differences according to age (Tab 1b). After a median of 27 months, 2-y OS was 79% (95CI: 51-86%) and EFS 56% (95CI: 32-75%). Twenty-four patients obtained a complete remission (CR) and 20 of them are in continuous CR after more than 12 months. Three patients progressed 1-8 months after ASCT and died. Most common non-hematologic grade 3-4 adverse events were gastrointestinal (10%) and infectious (8%). Conclusion: This study shows that sGA can identify older patients with R/R aggressive lymphoma who are able to tolerate and can benefit from high-dose therapy and ASCT. The poor response to second-line immunochemotherapy remains the major drawback of this approach since less than 50% of patients could actually receive ASCT. Nevertheless the 2-y survival of 65% in the intention to treat population is remarkable and sets the stage for the evaluation of new approaches such as CAR-T or bispecific antibodies also in older patients. A next step should be to explore the usefulness of sGA in the selection of candidates to these innovative treatments. Figure 1 Figure 1.

INTRODUCTION Treatment of Diffuse Large B cell lymphoma (DLBCL) in the elderly population is challenging as many patients (pts) are not eligible to receive standard curative therapy, due to comorbid conditions and to a higher susceptibility to the side effects of standard anthracycline containing regimens. Among currently available active drugs, Lenalidomide has been used in the setting of relapsed/refractory DLBCL both as monotherapy and in combination with rituximab, showing a good activity and an acceptable safety profile. We started a prospective, multicenter, single arm, phase II trial to demonstrate activity and safety of a chemo-free combination of lenalidomide + rituximab in older (≥ 70 years) untreated pts with DLBCL who were prospectively defined as frail according to the simplified comprehensive geriatric assessment (sCGA) (Tucci A. et al., Leuk Lymphoma. 2015 Apr). PATIENTS AND METHODS Pts were eligible if they were previously untreated DLBCL patients, older than 69 years and defined as frail according to sCGA. The treatment consisted of a 28-day cycle (R2) combining oral Lenalidomide (20 mg on days 1 to 21) and i.v. Rituximab (375 mg/m2 on day 1); a maximum number of 6 cycles was planned; response assessment was performed after cycles 4 and 6. At the end of the 6 th cycle, patients with partial or complete response continued treatment with Lenalidomide 10mg/d on days 1 to 21 every 28 days, until cycle 12or unacceptable toxicity. Final response was evaluated within 28 days after the last study drug administration. Primary study endpoint was Overall Response Rate (ORR) after 6 R2 cycles, defined according to Lugano 2014 criteria; co-primary endpoint was the rate of extra-hematological toxicity with CTCAE grade >2 and of death for any cause during the treatment The study was planned according to a two stage Simon design. A total of 68 pts had to be enrolled to complete the study. With 34 responses the study would be able to demonstrate the initial hypothesis of an improvement of response rate from 45% (p0) to 65% (P1) RESULTS From August 2018 to June 2021, 68 newly diagnosed frail DLBCL were enrolled in 18 Italian centers. Median age was 83 years (range 70-91) and 73% had stage III/IV; 57% had High risk IPI (i.e. 3-5 risk factors). 64 pts were confirmed eligible and started R2 treatment. The planned 6 courses of R2 were completed in 36 pts (56%). The median number of R2 cycles was 6 (1-6). Treatment was discontinued in 28 pts due to lymphoma progression (11 cases), extra-hematological toxicity (7), hematological toxicity (1), lost after 1 cycle and investigator choice after 5 cycles in CR in 1 case each, death in 7 cases (1 each for infection, pancytopenia, cachexia, ischemia and bowel infarction, and from unknown causes in 2 cases). At the end of 6 th R2 cycle 26 patients achieved a response (ORR 41%), 13 CR and 13 PR. After a median follow-up of 17 months, the overall survival, and progression free survival at 12 months were 69% (95CI 56-79%) and 55% (95%CI 42-66%), respectively. The duration of remission at 12 months was 72%. Regarding safety 46 events were reported including 31 extra-hematological toxicities > CTCAE grade 2: 7 cardio-vascular (1 resulting in death), 4 nervous system disorders (1 resulting in death), 10 gastro-intestinal, 3 infections, 6 skin and subcutaneous tissue disorders, 5 respiratory events (all resolved). The rate of grade 3-4 adverse events was higher than the highest allowed limit of 28. CONCLUSIONS The Reri is the first study to evaluate activity and safety of a chemo-free therapy in patients with diffuse large B-Cell Lymphoma who are not eligible for conventional cytotoxic therapy. Even if this study was not able confirm the initial activity hypothesis, activity of the R2 combination was observed in a significant proportion of cases warranting further exploration of chemo-free approach of elderly frail patient with DLBCL.

Introduction Non-pegylated liposomal doxorubicin (NPLD) is considered a good alternative to conventional doxorubicin for the treatment of older patients (pts) with aggressive lymphomas and/or at high risk for cardiological toxicity. The use of R-COMP for the treatment of older pts with DLBCL has been supported by several small retrospective studies . In this report we describe the characteristics and outcomes of pts who were prospectively enrolled in the Elderly Project (EP) and who were treated with R-COMP and compared them with pts treated with conventional R-CHOP. Methods. This analysis was conducted starting from the dataset of the EP study. The use of NPLD was allowed according to 648/96 law, treatment decision was left to physician discretion and was independent of frailty status. For the purposes of this analysis, we included all pts who were treated with full doses of R-CHOP and R-COMP. The study endpoint were progression free survival (PFS) and overall survival (OS). A propensity score analysis was conducted to account for the main confounding factors. Results Overall 691 out of 1163 pts of the EP were treated with R-CHOP (383; 55%) or R-COMP (308; 45%); median age was 71 and 76 years for R-CHOP and R-COMP, respectively (p < 0.001) (Table 1). Pts were similarly distributed among different IPI groups for R-COMP or R-CHOP. Based on simplified Geriatric Assessment (sGA) 88%, 11% and Conclusions Data from the prospective observational EP study did not show significant differences in terms of efficacy comparing R-COMP to standard R-CHOP. The higher frequency of UNFIT and FRAIL pts among those treated with NPLD suggests R-COMP is a good strategy to offer a curative treatment to these groups of pts. Figure 1 Figure 1.

Although health care managers often prefer to hire employees without tattoos, the source of this bias is unclear. One explanation is that tattoos are associated with being less responsible. An alternative explanation is that managers are concerned tattoos will hurt their organization's image. A sample of 187 dentists were shown a picture of a dental hygienist either with no tattoo, a small tattoo, or a large tattoo, and then asked about the hygienist. Results show that dentists do not associate tattoos with irresponsibility but are concerned about the fit of tattoos with the image of the practice. This means that dentists make hiring decisions based on stereotypes about customer stereotypes.

BACKGROUND: In 2014 we identified a new subset of DLBCL, defined as "IgM-secreting" (Cox MC & Di Napoli A , PLOS One 2014). This was characterised by poor prognostic features and outcome as well as frequent central nervous (CNS) system localizations. Furthermore, IgM-secretion, was an independent prognostic factor in multivariate analysis. Here we report on the largest series of IgM-secreting-DLBCL, from a multicentre Italian study. METHODS: The observational and biological study was approved by the Ethical Committee of the AUO Sant'Andrea, Italy. Enrolment criteria were: DLBCL with an associated IgM paraprotein diagnosed between 1st January 2010 and 31st December 2018 (IgM-secreting). Data were collected both prospectively and retrospectively from 17 Centres participating in the study. In addition, histopathology samples were centrally revised for immunohistochemistry (IHC) and FISH analyses. The control group (CTRL) consisted in a series of consecutive DLBCL, without an associated IgM-paraprotein (diagnosed between 01/01/2013 and 30/06/2016, enrolled in the Lymphoma Registry of the Lazio region (ReLLi Network). Last follow-up was carried out on 31st December 2019. RESULTS: 569 DLBCL cases were enrolled: 102 (17.9%) were IgM-secreting; 48 (8.4%) had a non-IgM paraprotein (IgA, IgG, or other), and 414 (72.7%) had no associated paraprotein (CTRL). IgM-secreting cases within the consecutive DLBCL patients enrolled in the ReLLi Registry were 41/466 (8.8%, 95CI 6.4-11.7%) while non IgM-paraprotein DLBCL cases were 11/466 (2.4%, 95CI 1.2-4.2%). The median level of IgM paraprotein was 17gr/L (range: 60 (p=.001); 2] advanced stage (pUNL (p=.008) ; 5] ≥2 Extra-nodal sites involved (p60, B-symptoms, bulky disease, IPI >low risk and IgM-secreting IgM showed a worse survival (all with p CONCLUSION: Our data confirm that IgM-secreting DLBCL: 1) represents a sizable proportion of non-DH DLBCL; 2) have poor prognostic features and 3) have mostly a non-GC phenotype. Furthermore, IgM secretion appears to be an independent prognostic factor for both PFS and OS. Studies to define the biological features of this new subset are ongoing.

Background Diffuse large B-cell lymphoma (DLBCL) is the most common non-Hodgkin lymphoma subtype, and approximately 50% of the patients are >60 years of age. Patients with relapsed/refractory (rr) disease have a poor prognosis with currently available treatments. Lenalidomide is available in Italy for patients with rrDLBCL based on a local disposition of the Italian Drug Agency. Subjects, Materials, and Methods An observational retrospective study was conducted in 24 Italian hematology centers with the aim to improve information on effectiveness and safety of lenalidomide use for rrDLBCL in real practice. Results One hundred fifty-three patients received lenalidomide for 21/28 days with a median of four cycles. At the end of therapy, there were 36 complete responses (23.5%) and 9 partial responses with an overall response rate (ORR) of 29.4%. In the elderly (>65 years) subset, the ORR was 33.6%. With a median follow-up of 36 months, median overall survival was reached at 12 months and median disease-free survival was not reached at 62 months. At the latest available follow-up, 29 patients are still in response out of therapy. Median progression-free survivals differ significantly according to age (2.5 months vs. 9.5 in the younger vs. elderly group, respectively) and to disease status at the latest previous therapy (15 months for relapsed patients vs. 3.5 for refractory subjects). Toxicities were manageable, even if 30 of them led to an early drug discontinuation. Conclusion Lenalidomide therapy for patients with rrDLBCL is effective and tolerable even in a real-life context, especially for elderly patients. Implications for Practice Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of non-Hodgkin lymphoma, and approximately 50% of the patients are >60 years of age. Patients with relapsed/refractory (rr) disease have a poor prognosis, reflected by the remarkably short life expectancy of 12 months with currently available treatments. The rrDLBCL therapeutic algorithm is not so well established because data in the everyday clinical practice are still poor. Lenalidomide for patients with rrDLBCL is effective and tolerable even in a real-life context, especially for elderly patients.
