INTRODUCTION:Anti-CD38 monoclonal antibodies (aCD38) are increasingly used in early lines of therapies in multiple myeloma (MM). Retreatment with aCD38-based regimen is a widely used practice in later lines. However, data coming from clinical trials are currently limited. EMMY is a noninterventional, prospective dynamic cohort study conducted in 73 centers in France to assess the real-life management of MM in France and which can explore the efficacy of aCD38-based retreatment. METHODS:Patients who initiated a second line of treatment with aCD38-based combinations after a first exposure to aCD38 were identified and described and the outcomes of progression-free survival (PFS) and overall survival (OS) were estimated. RESULTS:In the EMMY cohort, 286 patients received 2 lines of treatment including aCD38. For all aCD38-retreated patients, median PFS was estimated at 5.1 months. Median PFS was 23.6 m in patients sensitive to aCD38 and 4.6 in nonsensitive patients, P = .0003. Median OS was estimated at 17.3 months for all patients,14.8 months in patients nonsensitive to aCD38, and not reached (NR) in sensitive patients, P = .0004. No significant differences in PFS or OS were observed between the refractory and nonrefractory to aCD38 groups. CONCLUSION:These results of aCD38 retreatment in a large sample of real-life patients (n = 286) in extensively pretreated patients show that retreatment may be a meaningful strategy for aCD38 sensitive patients. These findings need to be investigated further while the use of aCD38 is emerging as a first-line treatment for newly diagnosed patients.

In patients with transplant-eligible newly diagnosed multiple myeloma, induction therapy with a quadruplet regimen prior to autologous transplant is the standard of care. The phase III IFM2020-02-MIDAS study (NCT04934475) assessed a minimal residual disease (MRD)-driven consolidation and maintenance strategy following induction with isatuximab, carfilzomib, lenalidomide, and dexamethasone (IsaKRD). Here, we report safety and efficacy outcomes of six 28-day cycles of IsaKRD. Between December 2021 and July 2023, 791 patients were enrolled across 72 centers. The median age was 59 years; 13% had ISS-stage III, 5% had R-ISS-stage III, and 8% had high-risk cytogenetics (IFM Linear Predictor cytogenetic score >1). Overall, 96% (N=757) of patients completed induction. The median CD34+ cell yield was 7 × 106/Kg, with 94% of patients able to proceed with a potential tandem transplant. The best overall response rate was 95%. In the intent-to-treat population, 91% achieved a very good partial response or better after induction, with MRD-negativity rates of 63% at 10-5 and 47% at 10-6. MRD-negativity rates differed across ISS stages and cytogenetic subgroups. During induction, 7 patients experienced disease progression, and 5 died due to disease progression (N=1), cardiac events (N=2), or other causes (N=2). The most common grade 3/4 adverse events were neutropenia (25%), thrombocytopenia (5%), and infections (7%); only 13% of patients reported any grade peripheral neuropathy. IsaKRD induction yielded deep responses and high MRD-negativity rates while ensuring successful stem cell collection, with no new safety signals. Continued follow-up of this ongoing study is required to confirm these findings.

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. The primary analysis of the Ro-CHOP phase III randomized controlled trial (ClinicalTrials.gov identifier: NCT01796002 ) established that romidepsin (Ro) plus cyclophosphamide, doxorubicin, vincristine, prednisone (CHOP) did not yield an increased efficacy compared with CHOP alone as first-line treatment of peripheral T-cell lymphoma. We report the planned final analysis 5 years after the last patient enrolled. With a median follow-up of 6 years, median progression-free survival (PFS) was 12.0 months compared with 10.2 months (hazard ratio [HR], 0.79 [95% CI, 0.62 to 1.005]; P = .054), while median overall survival was 62.2 months (35.7-86.6 months) and 43.8 months (30.1-70.2 months; HR, 0.88 [95% CI, 0.68 to 1.14]; P = .324) in the Ro-CHOP and CHOP arms, respectively. In an exploratory analysis, the median PFS in the centrally reviewed follicular helper T-cell lymphoma subgroup was significantly longer in the Ro-CHOP arm (19.5 v 10.6 months, HR, 0.703 [95% CI, 0.502 to 0.985]; P = .039). Second-line treatments were given to 251 patients with a median PFS2 and OS2 after relapse or progression of 3.3 months and 11.5 months, respectively. Within the limits of highly heterogeneous second-line treatments, no specific regimen seemed to provide superior disease control. However, a potential benefit was observed with brentuximab vedotin in association with chemotherapy even after excluding anaplastic large-cell lymphoma subtype or after adjusting for histology and international prognostic index in a multivariate model (HR for PFS, 0.431 [95% CI, 0.238 to 0.779]; P = .005).

Background and Objectives: Secondary ocular localizations of hematological malignancies are blinding conditions with a poor prognosis, and often result in a delay in the diagnosis. Materials and Methods: We describe a series of rare cases of ocular involvement in six patients with hematological malignancies, reportedly in remission, who presented secondary ocular localizations, challenging to diagnose. Two patients had an acute lymphoblastic leukemia (ALL) and developed either a posterior scleritis or a pseudo-panuveitis with ciliary process infiltration. One patient had iris plasmacytoma and developed an anterior uveitis as a secondary presentation. Two patients had a current systemic diffuse large B-cell lymphoma (DLBCL) and were referred either for intermediate uveitis or for papilledema and vitritis with secondary retinitis. Finally, one patient with an acute myeloid leukemia (AML) presented a conjunctival localization of a myeloid sarcoma. We herein summarize the current knowledge of ophthalmologic manifestations of extramedullary hematopathies. Results: Inflammatory signs were associated with symptomatic infiltrative lesions well displayed in either the iris, the retina, the choroid, or the cavernous sinus, from the admission of the patients in the ophthalmological department. These findings suggest that patients with ALL, AML, systemic DLBCL, and myeloma can present with ophthalmic involvement, even after having been reported as in remission following an effective systemic treatment and/or allograft. Conclusions: Early detection of hidden recurrence in the eyes may permit effective treatment. Furthermore, oncologists and ophthalmologists should be aware of those rare ocular malignant locations when monitoring patient’s progression after initial treatment, and close ophthalmologic examinations should be recommended when detecting patient’s ocular symptoms after treatment.

The registered dose for imatinib is 400 mg/d, despite high inter-patient variability in imatinib plasmatic exposure. Therapeutic drug monitoring (TDM) is routinely used to maximize a drug’s efficacy or tolerance. We decided to conduct a prospective randomized trial (OPTIM-imatinib trial) to assess the value of TDM in patients with chronic phase chronic myelogenous treated with imatinib as first-line therapy (NCT02896842). Eligible patients started imatinib at 400 mg daily, followed by imatinib [C]min assessment. Patients considered underdosed ([C]min < 1000 ng/mL) were randomized in a dose-increase strategy aiming to reach the threshold of 1000 ng/mL (TDM arm) versus standard imatinib management (control arm). Patients with [C]min levels ≥ 1000 ng/mL were treated following current European Leukemia Net recommendations (observational arm). The primary endpoint was the rate of major molecular response (MMR, BCR::ABL1IS ≤ 0.1%) at 12 months. Out of 133 evaluable patients on imatinib 400 mg daily, 86 patients had a [C]min < 1000 ng/mL and were randomized. The TDM strategy resulted in a significant increase in [C]min values with a mean imatinib daily dose of 603 mg daily. Patients included in the TDM arm had a 12-month MMR rate of 67% (95% CI, 51–81) compared to 39% (95% CI, 24–55) for the control arm (p = 0.017). This early advantage persisted over the 3-year study period, in which we considered imatinib cessation as a censoring event. Imatinib TDM was feasible and significantly improved the 12-month MMR rate. This early advantage may be beneficial for patients without easy access to second-line TKIs.

Peripheral T-cell lymphoma (PTCL) is a group of diseases with poor outcome and few therapeutic options. We aimed to assess the efficacy of bendamustine in real life cohort of patients.Between November 2009 and March 2015, 138 PTCL patients were treated with bendamustine in 27 centers. Population median age was 64 (28-89) years with male/female ratio of 1.4. There were mainly angio-immunoblastic (AITL = 71), PTCL-not otherwise specified (PTCL-NOS = 40) and anaplastic large cell lymphoma (ALCL = 8). The majority of patients (96%) had disseminated disease and extranodal localizations (77%). Median number of chemotherapy lines prior to bendamustine was 2 (1-8). Median duration of response (DoR) after the last chemotherapy prior to bendamustine was 4.3 months (1-70) and 50% of patients had refractory disease.Median number of administered bendamustine cycles was 2 (1-8) and 72 patients (52%) received less than 3 mostly because of disease progression. Median dose was 90 (50-150) mg/m². Overall response rate (ORR) was 32.6% with complete response (CR) rate of 24.6% and median DoR was 3.3 months (1-39). AITL patients were more sensitive than PTCL-NOS patients (ORR: 45.1 versus 20%, p = 0.01). Median PFS and OS were 3.1 (0.2-46.3) and 4.4 (0.2-55.4) months. On multivariate analysis, refractory disease (p = 0.001) and extranodal localization (p = 0.028) adversely influenced ORR. Grade 3-4 thrombocytopenia, neutropenia and infections were reported in 22, 17 and 23% of cases respectively.Bendamustine as single agent could be considered as a therapeutic option for relapsed or refractory PTCL, particularly in chemosensitive or AITL patients. Combinations of bendamustine with other drugs warrant further evaluation.

The purpose of our study is to determine the outcome of patients with systemic non-Hodgkin lymphoma presenting with neurologic localization at diagnosis, as well as the impact of consolidation in terms of high-dose therapy followed by autologous stem cell transplantation. Newly diagnosed non-Hodgkin lymphoma patients with concomitant systemic and neurological involvement at diagnosis were included in this study. Sixty patients (37 males; 25 females) were included. Median age was 61 years (23–85 years). Histological subtype was mainly diffuse large B-cell lymphoma (n=54; 90%). The International prognostic index was over 2 in 41 (72%) patients. Median number of extranodal sites was 2 (range: 1–5). Central nervous system involvement alone was documented in 48 patients. Paravertebral involvement with epidural mass and cord compression and positive cerebrospinal fluid were present in 7 patients. Five patients had both central nervous system and epidural involvement. First-line chemotherapy was mainly anthracycline-based (88%) plus high-dose methotrexate (74%) with or without cytarabine. Consolidation with high-dose therapy followed by autologous stem cell transplantation was performed in 19 patients. For the whole population, overall response rate after induction chemotherapy was 76%. Three-year progression-free survival and overall survival were 42±7% and 44±7%, respectively. For patients under 66 years of age, consolidation strategy using high-dose therapy followed by autologous stem cell transplantation positively impacted 3-year overall survival and progression free survival (P=0.008) and (P=0.003), respectively. In multivariate analysis, high-dose therapy had a positive impact on 3-year overall survival and progression-free survival for the whole population as well as for patients under 66 years old in CR after induction therapy (OS [HR=0.22 (0.07–0.67)] and progression-free survival [HR=0.17 (0.05–0.54)]). In conclusion, non-Hodgkin lymphoma prognosis with concomitant systemic and neurological involvement at diagnosis is poor with a high risk of relapse when treated with conventional chemotherapies alone. This retrospective study supports the feasibility and the potential benefit of a consolidative strategy with high-dose therapy followed by autologous stem cell transplantation in this subset of patients. This strategy and the best intensive chemotherapy regimen remain to be validated in prospective trials.

Purpose To determine the characteristics of Non-Hodgkin’s lymphoma (NHL) patients with concomitant systemic and central nervous system localization at diagnosis, as well as the impact of consolidation with high dose chemotherapy followed by hematopoietic stem cell rescue on outcome Patients and Methods Newly diagnosed NHL patients with concomitant systemic and cerebral or meningeal involvement at diagnosis have been included in this study. Patients were retrieved from the database of the participating centers of the LYSA and LOC study groups Results Sixty-five patients (37 males; 28 females) were included. Median age was 60 years (23-85). Histological subtype was mainly diffuse large B-cell lymphoma (n=54; 83%). The IPI was >2 in 43 (66%) patients. LDH level was elevated in 27 (55%) patients. Median number of extranodal positive sites was 2 (1-5) and bone marrow involvement was documented in 30 (46%) patients. CNS involvement was documented in 51 patients. Paravertebral and epidural compressive mass with (n=5) or without (n=2) CSF involvement were present. Five patients had both CNS and peripheral nervous system involvement. Anthracycline-based chemotherapy with high dose metothrexate with or without cytarabine was the most chemotherapy used. Autologous stem cell transplantation was performed in 21 patients in response. BEAM (n=9) or thiotepa-based (n=9) conditioning regimen was the most intensive chemotherapy used before autologous SCT Post-chemotherapy ORR was 77%(CR69%;PR8%). 3-year overall survival (OS) and progression free survival (PFS) were 48±7% and 46±7% respectively. The consolidation strategy using high dose chemotherapy and autologous stem cell transplant positively impacted patient’s outcome. For the whole group as well as for patients ≤65 years, the 3-year OS and PFS were (77%vs29%;p=0.002) and (77%vs25%;p=0.001) and (75% vs 37%;p=0.002) and (75%vs32%;p=0.007) respectively. In multivariate analysis and for the whole group of patients, the absence high dose therapy had a negative impact on 3-year OS and PFS [p=0.003;HR=5.05[1.76-14.49]) and PFS by [p=0.002;HR=5.46(1.91-15.26)] respectively. This is remained true for younger patients 65 years or less who had poorer 3-year OS [p=0.036;HR=3.41 (1.08-10.75)]. Conclusion First line consolidative high dose therapy followed by autologous SCT in patients with systemic and neuro-meningeal NHL improve patient’s outcome Disclosures No relevant conflicts of interest to declare.

We report here three cases of cup-like leukemia, a rare and underdiagnosed form of acute myeloblastic leukemia. Clinical and biological findings are relatively stereotypical : high blood cell counts, high frequency of NPM1 and FLT3 mutations and normal karyotype, and may resemble microgranular variant of acute promyelocytic leukemia because of frequent disseminated intravascular coagulation, mature phenotypic feature with low or absent expression of CD34 and HLADR and peculiar blastic morphology (proeminent nuclear invaginations).Therefore, recongnizing cup-like nuclear leukemia is important to avoid misdiagnosis of promyelocytic leukemia and should guide specific molecular analyses.

Hodgkin lymphoma (HL) is considered one of the most curable forms of cancer, with a 5-year survival rate of up to 90% [1]. Extranodal HL represents only 15% of HL, and is mainly observed in advance...

We reported here a case of acute myeloid leukaemia (AML) in a 28-year-old male patient, which diagnosis is discussed according to the different classifications. This case focused on some new criteria and changes in the new WHO classification (2008) of AML, especially when erythroid precursors represent over 50% of bone marrow nucleated cells. It also pointed on some gene mutations (NPM1, CEPBA, FLT3, WT1…) and their prognostic features in AML with a normal karyotype, leading to individualize two new provisional entities in the WHO classification of tumours of hematopoietic and lymphoid tissues 2008.

The efficacy of Pegfilgrastim (PF) in decreasing the duration of neutropenia has been proved after standard dose of chemotherapy. Results of PF after high dose chemotherapy (HDC) and autologous peripheral blood stem cells transplantation ASCT) are lacking. We studied the efficacy of PG in patients receiving HDC and ASCT for lymphoproliferative disease. Fifteen consecutive patients (8 males; 7 females) were onrolled in the study from September 2003 through March 2004. Median age of the patients was 56 years. Diseases were multiple myeloma in 5 patients, diffuse large cell non-Hodgkin's lymphoma (NHL) in 3 patients, follicular lymphoma in 4 patients, mantle cell lymphoma in one patient, and primary central nervous system lymphoma PCNSL) in 2 patients. All patients were eligible for HDC and ASCT per institutional criteria. Stem cells were collected with peripheral blood pheresis after high dose cyclophosphamide (7 cases); high dose Ara-c (5 cases); ifosfamide (1 case); CHOP-like chemotherapy (1 case); or in steady state (1 case). All the patients received daily G-CSF (5 to 10 mcg/kg). Three different conditioning regimens were used. Patients with multiple myeloma received high dose melphalan (200 mg/m²), patients with PCNSL received a combination of high dose Thiotepa (750 mg/m²), Busulfan (12 mg/kg), and Cyclophosphamide (120 mg/kg), and patients with NHL received a BEAM chemotherapy. PF was administered as a single subcutaneous injection of 6 mg at day +3 after stem cell infusion, except for one patient whose injection was done on day 4. No adverse event attributable to PF was observed. There were no toxic death on study. All patients engrafted neutrophils and platelets. The median time to neutrophils engraftment (> 500/mm3) was 7 days (range, 4–12). Febrile neutropenia was almost constant (14/15) but never exceed OMS grade 2. Median number of days with IV antibiotics was 7 days (range 5–22). These preliminary data show that a fixed dose of 6 mg of PF given subcutaneously at day +3 after HDC and ASCT is safe and effective. A cost efficacy study is warranted to compare PF and daily dose of standard G-CSF after ASCT.
