ABSTRACT
Scedosporium spp. and Lomentospora prolificans are emerging non-Aspergillus filamentous fungi. The Scedosporiosis/lomentosporiosis Observational Study we previously conducted reported frequent fungal vascular involvement, including aortitis and peripheral arteritis. For this article, we reviewed 7 cases of Scedosporium spp. and L. prolificans arteritis from the Scedosporiosis/lomentosporiosis Observational Study and 13 cases from published literature. Underlying immunosuppression was reported in 70% (14/20) of case-patients, mainly those who had solid organ transplants (10/14). Osteoarticular localization of infection was observed in 50% (10/20) of cases; infections were frequently (7/10) contiguous with vascular infection sites. Scedosporium spp./Lomentospora prolificans infections were diagnosed in 9 of 20 patients ≈3 months after completing treatment for nonvascular scedosporiosis/lomentosporiosis. Aneurysms were found in 8/11 aortitis and 6/10 peripheral arteritis cases. Invasive fungal disease--related deaths were high (12/18 [67%]). The vascular tropism of Scedosporium spp. and L. prolificans indicates vascular imaging, such as computed tomography angiography, is needed to manage infections, especially for osteoarticular locations.

Obinutuzumab and lenalidomide (referred to as the GALEN combination) is an active immunomodulatory combination with a manageable safety profile in multiple types of lymphoma. We report efficacy and safety results for the phase 2 GALEN study in previously untreated patients with advanced follicular lymphoma (FL). Eligible patients aged ≥18 years had an Eastern Cooperative Oncology Group performance status ≤2 and high-tumor burden, grade 1 to 3a FL. Induction treatment was obinutuzumab (1000 mg IV, days 8, 15, and 22, cycle 1; day 1, cycles 2-6) plus lenalidomide (20 mg/d, days 1-21, cycle 1; days 2-22, cycles 2-6) for six 28-day cycles. Maintenance included obinutuzumab (1000 mg every 2 cycles) plus lenalidomide (10 mg, days 2-22) for ≤12 cycles (year 1) followed by obinutuzumab (1000 mg every 56 days) for 6 cycles (year 2). The primary end point was complete response rate (CRR) after induction per the 1999 International Working Group criteria. From October 2015 to February 2017, a total of 100 patients were enrolled. CRR after induction was 47%, and the overall response rate (ORR) was 92%. Post hoc analyses per the 2014 Lugano classification, including patients with missing bone marrow assessments, identified an additional 13 patients fulfilling CRR criteria, resulting in a complete metabolic response of 80% and an ORR of 94%. At a median follow-up of 3.7 years, 3-year progression-free survival and overall survival were 82% and 94%, respectively. The most common adverse event was neutropenia (48% any grade; 47% grade ≥3). Only 2% of patients presented with febrile neutropenia; others were mainly grade ≤2. No other specific grade ≥3 toxicity occurred at a frequency >3%. Overall, these results showed promising clinical efficacy for the chemotherapy-free GALEN backbone in previously untreated patients with high tumor burden FL. Except for neutropenia, the safety profile of the combination is remarkable. The study was registered at clinicaltrials.gov as #NCT01582776.

The treatment of primary vitreoretinal lymphoma (PVRL) remains controversial regarding the use of local, systemic, or combined treatments. The aim of this study was to analyze the efficacy and toxicity of intravenous high-dose methotrexate (IV HD-MTX) based systemic therapy in a uniformly treated population of PVRL patients. From a nationwide French database, we retrospectively selected 59 patients (median age: 70 years, median Karnofsky Performance Status: 90%) with isolated PVRL at diagnosis who received first-line treatment with HD-MTX between 2011 and 2018. 8/59 patients also received a local treatment. No deaths or premature discontinuations of MTX due to toxicity were reported. A complete response was obtained in 40/57 patients after chemotherapy. Before treatment, IL-10 was elevated in the aqueous humor (AH) or in the vitreous in 89% of patients. After treatment, AH IL-10 was undetectable in 87% of patients with a CR/uCR/PR and detectable in 92% of patients with PD/SD. After a median follow-up of 61 months, 42/59 (71%) patients had relapsed, including 29 isolated ocular relapses as the first relapse and a total of 22 brain relapses. The median overall survival, progression-free survival, ocular-free survival and brain-free survival were 75, 18, 29 and 73 months, respectively. IV HD-MTX based systemic therapy as a first-line treatment for isolated PVRL is feasible, with acceptable toxicity, even in an elderly population. This strategy seems efficient to prevent brain relapse with prolonged overall survival. However, the ocular relapse rate remains high. New approaches are needed to improve local control of this disease, and ocular assessment could be completed by monitoring AH IL-10.

The optimal consolidation strategy for primary central nervous system lymphoma (PCNSL) remains controversial. Preventing radio-induced neurotoxicity of consolidation treatment through reduced-dose whole-brain radiotherapy (rdWBRT) at a dose of 23.4 Gy is an interesting alternative to conventional WBRT in patients aged <60 years. From the LOC Network (Network for Oculo-cerebral Lymphomas) database, we retrospectively selected patients with PCNSL aged <60 years who showed complete (CR) or unconfirmed CR after high-dose methotrexate-based chemotherapy and had received consolidation rdWBRT as the first-line treatment. If available, prospective neuropsychological follow-ups were reported. Twenty-nine patients diagnosed between 2013 and 2018 met the study selection criteria. Nine (31%) patients experienced relapse during the follow-up, with a median time from radiotherapy to recurrence of 8.7 months (interquartile range, 4-11.5). Five of those patients received salvage treatment and consolidation with intensive chemotherapy and autologous stem cell transplantation. Progression-free survival rates were 89% (95% confidence interval [CI] 79%-100%), 72% (95% CI, 56%-88%), and 69% (95% CI, 52%-85%) at 1, 2, and 5 years, respectively. Overall survival rates were 100%, 89% (95% CI, 79%-100%), and 86% (95% CI, 74%-99%) at 1, 2, and 5 years, respectively, and were consistent with those observed for standard-dose WBRT (sdWBRT). No prognostic factor was identified. The results of the 36-month neuropsychological follow-up for a subset of patients appeared reassuring, with most patients exhibiting maintenance of or improvements in their baseline conditions. Our results, combined with phase 2 study results, support the use of rdWBRT instead of sdWBRT as a consolidation treatment in <60-year-old patients showing CR after induction treatment.

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 previously reported the results of a randomized phase II study in patients with newly diagnosed primary CNS lymphoma (age 18-60 years). Patients were treated with high-dose methotrexate-based induction chemotherapy followed by whole-brain radiotherapy (WBRT) or high-dose chemotherapy (thiotepa-busulfan-cyclophosphamide) with autologous stem-cell transplantation (ASCT). The median follow-up was 33 months. In this report, we provide long-term data (median follow-up, 8 years) regarding the outcomes and toxicities. Fifty-three and 44 patients received induction chemotherapy followed by WBRT or ASCT, respectively. Their 8-year event-free survival from random assignment was 67% and 39% in the ASCT and WBRT arms, respectively (P = .03), with a significantly lower risk of relapse after ASCT (hazard ratio, 0.13; P < .001). One third of patients who relapsed after WBRT were alive after salvage treatment. Five and four patients died of ASCT and WBRT-related toxicities, respectively. The 8-year overall survival was 69% and 65% in the ASCT and WBRT arms, respectively (not significant). Balance (52% v 10%, P ≤ 0.001) and neurocognition (64% v 13%, P < .001) significantly deteriorated after WBRT compared with ASCT during the follow-up. This study shows that 40 Gy WBRT should be avoided in first-line treatment because of its neurotoxicity and suboptimal efficacy in reducing relapses while ASCT appears to be highly efficient in preventing relapses.

We analysed the therapeutic outcomes of all consecutive patients with primary central nervous system lymphoma (PCNSL) registered in the prospective French database for PCNSL and treated with intensive chemotherapy (IC) followed by autologous stem cell transplantation (IC-ASCT) between 2011 and November 2019 (271 patients recruited, 266 analysed). In addition, treatment-related complications of thiotepa-based IC-ASCT were analysed from the source files of 85 patients from 3 centers. Patients had received IC-ASCT either in first-line treatment (n = 147) or at relapse (n = 119). The median age at IC-ASCT was 57 years (range: 22-74). IC consisted of thiotepa-BCNU (n = 64), thiotepa-busulfan (n = 24), BCNU-etoposide-cytarabine-melphalan (BEAM, n = 36) and thiotepa-busulfan-cyclophosphamide (n = 142). In multivariate analysis, BEAM and ASCT beyond the first relapse were adverse prognostic factors for relapse risk. The risk of treatment-related mortality was higher for ASCT performed beyond the first relapse and seemed higher for thiotepa-busulfan-cyclophosphamide. Thiotepa-BCNU tends to result in a higher relapse rate than thiotepa-busulfan-cyclophosphamide and thiotepa-busulfan. This study confirms the role of IC-ASCT in first-line treatment and at first-relapse PCNSL (5-year overall survival rates of 80 and 50%, respectively). The benefit/risk ratio of thiotepa-busulfan/thiotepa-busulfan-cyclophosphamide-ASCT could be improved by considering ASCT earlier in the course of the disease and dose adjustment of the IC.

Autologous stem cell transplantation (ASCT) as first-line therapy for follicular lymphoma (FL) remains controversial. The multicenter study randomized 172 patients with untreated FL for either immunochemotherapy or high-dose therapy (HDT) followed by purged ASCT. Conditioning was performed with total body irradiation (TBI) and cyclophosphamide. The 9-year overall survival (OS) was similar in the HDT and conventional chemotherapy groups (76% and 80%, respectively). The 9-year progression-free survival (PFS) was higher in the ASCT than the chemotherapy group (64% vs 39%; P = .004). A PFS plateau was observed in the HDT group after 7 years. On multivariate analysis, OS and PFS were independently affected by the per-formance status score, the number of nodal areas involved, and the treatment group. Secondary malignancies were more frequent in the HDT than in the chemotherapy group (6 secondary myelodysplastic syndrome/acute myeloid leukemia and 6 second solid tumor cancers vs 1 acute myeloid leukemia, P = .01). The occurrence of a PFS plateau suggests that a subgroup of patients might have their FL cured by ASCT. However, the increased rate of secondary malignancies may discourage the use of purged ASCT in combination with TBI as first-line treatment for FL. This trial has been registered with ClinicalTrials.gov under identifier NCT00696735.

BACKGROUND: The complexity of the hospital-city care pathway is a real challenge because of the lack of coordination and communication between many stakeholders. As part of a call for projects from the General Directorate of Healthcare Provision, an experiment involving private oncology coordinating nurses was developed to address this issue. To our knowledge, there is no evaluation so far of such a protocol . METHODS: This single-center retrospective study focused on data from the ONC'IDEC program between 2015 and 2018, where 28 private nurses provided a 24/7 hotline. The objective was to qualitatively assess the coordination of this system. The nature and number of calls, patient satisfaction and medico-economic parameters were assessed. RESULTS: More than a hundred patients (n=114) were included in this device (mean age: 72 ± 12 years). The most frequent reasons for calls concerned the patient's general condition (35 %) and home treatment follow-ups (13 %) but also referrals to the primary doctor (4 %), which helped avoiding hospitalizations. The patients were satisfied with the experiment (overall score of 8.4/10). DISCUSSION: Thanks to the ONC'IDEC program, patients were able to benefit from more appropriate care through a privileged interlocutor by making their care pathway more fluid and avoiding hospitalizations. It would be interesting to confirm these results by means of a study with a higher level of evidence, by comparing this protocol to conventional hospital coordination.

OBJECTIVE: Real-life studies on patients with primary CNS lymphoma (PCNSL) are scarce. Our objective was to analyze, in a nationwide population-based study, the current medical practice in the management of PCNSL. METHODS: The French oculo-cerebral lymphoma network (LOC) database prospectively records all newly diagnosed PCNSL cases from 32 French centers. Data of patients diagnosed between 2011 and 2016 were retrospectively analyzed. RESULTS: We identified 1,002 immunocompetent patients (43% aged >70 years, median Karnofsky Performance Status [KPS] 60). First-line treatment was high-dose methotrexate-based chemotherapy in 92% of cases, with an increasing use of rituximab over time (66%). Patients <60 years of age received consolidation treatment in 77% of cases, consisting of whole-brain radiotherapy (WBRT) (54%) or high-dose chemotherapy with autologous stem cell transplantation (HCT-ASCT) (23%). Among patients >60 years of age, WBRT and HCT-ASCT consolidation were administered in only 9% and 2%, respectively. The complete response rate to initial chemotherapy was 50%. Median progression-free survival was 10.5 months. For relapse, second-line chemotherapy, HCT-ASCT, WBRT, and palliative care were offered to 55%, 17%, 10%, and 18% of patients, respectively. The median, 2-year, and 5-year overall survival was 25.3 months, 51%, and 38%, respectively (<60 years: not reached [NR], 70%, and 61%; >60 years: 15.4 months, 44%, and 28%). Age, KPS, sex, and response to induction CT were independent prognostic factors in multivariate analysis. CONCLUSIONS: Our study confirms the increasing proportion of elderly within the PCNSL population and shows comparable outcome in this population-based study with those reported by clinical trials, reflecting a notable application of recent PCNSL advances in treatment.

OBJECTIVES: to prospectively evaluate the incidence and the clinical relevance on hematopoietic reconstitution of HHV-6 infection in autologous hematopoietic stem cell transplantation (ASCT) recipients. METHODS: HHV-6 DNA load was measured in whole blood specimens once during the 7 days before stem cell re-infusion and once a week after transplantation until hematopoietic recovery. Active HHV-6 infection was defined by 2 consecutive positive DNA loads. RESULTS: from July 2012 to February 2015, 196 adult patients undergoing ASCT were enrolled. Twenty-two (11.2%) patients developed active HHV-6 infection with a cumulative incidence of 19% at 40 days after transplantation. The onset of active HHV-6 infection occurred with a median of 13 days after stem cell re-infusion. HHV-6 infection was associated with an increased frequency of non-infectious complications (OR = 5.05; 95%CI 1.78-14.32; P < 0.001). Moreover, the severity of these non-infectious complications was higher in recipients exhibiting HHV-6 infection (OR = 4.62; 95%CI 1.32-16.2; p < 0.01). Delayed neutrophils 10 (IQR: 8-14) vs 8 (IQR: 6-11) days and platelets recoveries 15 (IQR: 11.8-18.5) vs 8 (IQR: 4-14) days were observed in patients with active HHV-6 infection compared to non-infected ones. CONCLUSIONS: in this study, 11.2% ASCT recipients presented active HHV-6 infection associated with significantly delayed hematologic reconstitution.

PURPOSE: To determine the efficacy and toxicity of chemoimmunotherapy followed by either whole-brain radiotherapy (WBRT) or intensive chemotherapy and autologous stem-cell transplantation (ASCT) as a first-line treatment of primary CNS lymphoma (PCNSL). PATIENTS AND METHODS: Immunocompetent patients (18 to 60 years of age) with untreated PCNSL were randomly assigned to receive WBRT or ASCT as consolidation treatment after induction chemotherapy consisting of two cycles of R-MBVP (rituximab 375 mg/m2 day (D) 1, methotrexate 3 g/m2 D1; D15, VP16 100 mg/m2 D2, BCNU 100 mg/m2 D3, prednisone 60 mg/kg/d D1-D5) followed by two cycles of R-AraC (rituximab 375 mg/m2 D1, cytarabine 3 g/m2 D1 to D2). Intensive chemotherapy consisted of thiotepa (250 mg/m2/d D9; D8; D7), busulfan (8 mg/kg D6 through D4), and cyclophosphamide (60 mg/kg/d D3; D2). WBRT delivered 40 Gy (2 Gy/fraction). The primary end point was 2-year progression-free survival. Cognitive outcome was the main secondary end point. Analysis was intention to treat in a noncomparative phase II trial. RESULTS: Between October 2008 and February 2014, 140 patients were recruited from 23 French centers. Both WBRT and ASCT met the predetermined threshold (among the first 38 patients in each group, at least 24 patients were alive and disease free at 2 years). The 2-year progression-free survival rates were 63% (95% CI, 49% to 81%) and 87% (95% CI, 77% to 98%) in the WBRT and ASCT arms, respectively. Toxicity deaths were recorded in one and five patients after WBRT and ASCT, respectively. Cognitive impairment was observed after WBRT, whereas cognitive functions were preserved or improved after ASCT. CONCLUSION: WBRT and ASCT are effective consolidation treatments for patients with PCNSL who are 60 years of age and younger. The efficacy end points tended to favor the ASCT arm. The specific risk of each procedure should be considered.

Rare cases of acute promyelocytic leukemia (APL) are associated with a t(11;17) translocation and a PLZF-RARalpha fusion transcript. Because of molecular specificities of the fusion protein, ATRA efficiency is often reduced in these cases. We present herein the case of an 83-year old patient which has been successfully treated by ATRA and Daunorubicin. The described quantitative RT-PCR method allowed successful monitoring and confirmation of the molecular response.

BACKGROUND: Treatment of relapsed/refractory (R/R) primary CNS lymphoma (PCNSL) is poorly defined, because randomized trials and large studies are lacking. The aim of this study was to analyze the characteristics, management, and outcome of R/R PCNSL patients after first-line therapy in a nationwide cohort. METHODS: We analyzed R/R PCNSL patients following first-line treatment who had been prospectively registered in the database of the French network for oculocerebral lymphoma (LOC) between 2011 and 2014. RESULTS: Among 563 PCNSL patients treated with first-line therapy, we identified 256 with relapsed (n = 93, 16.5%) or refractory (n = 163, 29.0%) disease. Patients who were asymptomatic at relapse/progression (25.5%), mostly diagnosed on routine follow-up neuroimaging, tended to have a better outcome. Patients who received salvage therapy followed by consolidation (mostly intensive chemotherapy plus autologous hematopoietic stem cell transplantation [ICT + AHSCT]) experienced prolonged survival compared with those who did not receive salvage or consolidation therapy. Independent prognostic factors at first relapse/progression were: KPS ≥ 70 vs KPS < 70), sensitivity to first-line therapy (relapsed vs refractory disease), duration of first remission (progression-free survival [PFS] ≥1 y vs <1 y), and management at relapse/progression (palliative care vs salvage therapy). Patients who relapsed early after first-line therapy (ie, PFS < 1 y) had a poor outcome, comparable to that of refractory patients. Conversely, patients experiencing late relapses (PFS ≥ 1 y) and/or undergoing consolidation with ICT + AHSCT experienced prolonged survival. CONCLUSIONS: About a third of PCNSL patients are primary refractory to first line treatment. We identified several independent prognostic factors that can guide the management of R/R PCNSL patients.

Gemtuzumab ozogamicin (GO) is a humanized monoclonal antibody anti-CD33 conjugated with calicheamicin and was indicated for acute myeloid leukemia (AML) patients. It was initially approved in 2000 by FDA thank to promising results from a phase II trial including elderly relapsing AML patients. Numerous studies evaluated this treatment as salvage and frontline therapy in various regimens including associations with intensive chemotherapy. Based on the results from a randomized phase III trial, this agent was withdrawal because of no evidence for its benefit in terms of survival associated with excessive toxicity. Other phase III trials were then reported and show potentially better efficacy/toxicity profile. We review here the results of main trials interesting this agent, which is so far only available in a compassionate ATU program in France for the treatment of relapsing CD33+ AML patients.

Hematology Oncology has a rich history including few crucial therapeutic innovations. These were possible because of the evolution of the cell and molecular biology allowing a better understanding of basic mechanisms of cancerogenesis. We propose here to summarize the most important therapeutic innovations since the beginning of Hematology/Oncology history. We also describe evolution of therapeutic strategies themselves. New insights and therapeutic perspectives for next future are also discussed.

Diffuse eosinophilic fasciitis (Shulman disease) is a rare sclerodermiform syndrome that, in most cases, resolves spontaneously or after corticosteroid therapy. It has been associated with hematologic disorders, such as aplastic anemia. The clinical features and long-term outcomes of patients with eosinophilic fasciitis and associated aplastic anemia have been poorly described. We report the cases of 4 patients with eosinophilic fasciitis and associated severe aplastic anemia. For 3 of these patients, aplastic anemia was refractory to conventional immunosuppressive therapy with antithymocyte globulin and cyclosporine. One of the patients received rituximab as a second-line therapy with significant efficacy for both the skin and hematologic symptoms. To our knowledge, this report is the first to describe rituximab used to treat eosinophilic fasciitis with associated aplastic anemia. In a literature review, we identified 19 additional cases of eosinophilic fasciitis and aplastic anemia. Compared to patients with isolated eosinophilic fasciitis, patients with eosinophilic fasciitis and associated aplastic anemia were more likely to be men (70%) and older (mean age, 56 yr; range, 18-71 yr). Corticosteroid-containing regimens improved skin symptoms in 5 (42%) of 12 cases but were ineffective in the treatment of associated aplastic anemia in all but 1 case. Aplastic anemia was profound in 13 cases (57%) and was the cause of death in 8 cases (35%). Only 5 patients (22%) achieved long-term remission (allogeneic hematopoietic stem cell transplantation: n = 2; cyclosporine-containing regimen: n = 2; high-dose corticosteroid-based regimen: n = 1).
