Multiple myeloma survival has significantly improved in recent years, due to novel agents that are available for treatment. The anti-CD38 monoclonal antibody Daratumumab is particularly efficient for patients with relapse/refractory disease, and many studies have shown its unprecedented efficacy also as a first treatment. However, to avoid the incidence of infusion reactions, long infusion schedules of 8 h at first dose and 4 h in the following doses are required, which can reduce the compliance of patients and health care professionals. A reduced infusion time of 90 min has been reported previously, but data are missing on the prolonged safety of this over time as well as the efficacy of this approach. In this work, we investigate the safety of 484 rapid Daratumumab infusions given early after the second dose over a 22 months period in 39 myeloma patients.

Venetoclax in association with decitabine as effective bridge to transplant in a case of relapsed early T-cell lymphoblastic leukemia.

Clin Case Rep 2020 Oct 7;8(10):2000-2002. Epub 2020 Jul 7.

A case of an early-relapsed high-risk T-ALL with high BCL-2 expression on leukemic blasts was successfully treated with decitabine and venetoclax, achieving a CR. We suggest decitabine and venetoclax should be synergistic in BCL2-positive ALL.

Prognostic impact of tumor-associated macrophages, lymphocyte-to-monocyte and neutrophil-to-lymphocyte ratio in diffuse large B-cell lymphoma.

Am J Blood Res 2020 25;10(4):97-108. Epub 2020 Aug 25.

Unit of Pathology, Department of Medical Biotechnologies, University of Siena Siena, Italy.

Introduction: Microenvironment has a prognostic influence in diffuse large B-cell lymphoma (DLBCL); among its components, tumor-associated macrophages (TAM) play a leading role. TAM can be classified into M1 (anti-tumor) and M2 (pro-tumor). Another prognostic factor could be represented by lymphocyte-to-monocyte and neutrophil-to-lymphocyte ratio (LMR and NLR).

Objective: The aim of the study is to evaluate the prognostic impact of M1 and M2 TAM subtypes, LMR and NLR in DLBCL.

Methods: We analyzed 37 consecutive patients between 2009 and 2013. Out of 37 patients, 28/37 (75.6%) received R-CHOP/CHOP-like regimens, 9/37 (24.4%) less intensive therapies. Immunohistochemistry was performed with antibodies against CD68 and CD163. We divided our cohort into 2 categories according to the Steidl score. TAM who coexpressed CD68 and CD163 were considered as M2. For LMR and NLR we used previously published cut-offs of 2.71 and 2.81.

Results: CR rate was 70.3%; we did not record a significant correlation between CD68+ TAM, CD163+ TAM, CD68+/CD163+ TAM, LMR, NLR and CR. We observed a reduced PFS in patients with IPI ≥ 2 and high M2 TAM expression and a trend between higher expression of CD68+ TAM and improved PFS.

Conclusion: M2 TAM could have a prognostic role for IPI ≥ 2 DLBCL patients receiving R-CHOP, which thus warrants further investigation.

How to manage early-stage follicular lymphoma.

Expert Rev Hematol 2020 10 20;13(10):1093-1105. Epub 2020 Sep 20.

Unit of Hematology, Azienda Ospedaliera Universitaria Senese & University of Siena , Siena, Italy.

Introduction: Early-stage follicular lymphoma (FL) is characterized by good prognosis and can be cured with involved-field radiotherapy (IF-RT) in most cases. PET scan is a milestone of diagnostic work-up, with the aim of identifying a truly localized disease; however, staging in most of the studies was without PET.

Areas Covered: We have searched in MEDLINE (inclusive dates 1994-2020) data about localized FL management. While high-quality evidence is lacking, current guidelines recommend IFRT or involved-site RT as first-line treatment in limited stages FL. Since a significant proportion of disease relapse occurred in non-irradiated areas, it has been hypothesized that occult disease could be present at diagnosis and could persist after RT, contributing to relapse. Available treatment options include watch-and-wait, chemotherapy, RT plus chemo- or chemo-immunotherapy, and RT combined with rituximab (R).

Expert Opinion: RT combined with chemotherapy could increase PFS, but a clear OS benefit is lacking and toxic effects could be unacceptable. A promising strategy is represented by R combined with IF-RT, with low relapse rate outside the radiation fields and without the toxicity reported with chemotherapy. The study of prognostic factors in PET-staged patients, the reduction of RT fields and doses, and a response-adapted strategy represent new perspectives to investigate.

Coexistence of Serum Monoclonal Gammopathy of Uncertain Significance and Hodgkin Lymphoma.

Indian J Hematol Blood Transfus 2020 Apr 12;36(2):390-392. Epub 2019 Dec 12.

An uncommon association between multiple myeloma and Hodgkin lymphoma (HL) was observed in some case reports, while an association with monoclonal gammopathy of uncertain significance (MGUS) is exceedingly rare. We have diagnosed 110 HL cases from 2008 to 2018; here we report 4 HL cases associated with MGUS. MGUS was diagnosed before HL (1 case), together with HL (1 case) or after HL (2 cases). M-component was IgG/k (3 cases) and IgG/k and IgG/λ (1 case), MGUS was not influenced by HL treatment (2 cases), raised after therapy (1 case), while in the last case MGUS appeared after ASCT while HL was in complete remission. We suggest to further study a possible link between MGUS and HL and to perform serum immunofixation if protein electrophoresis shows a suspected discrete band. The comprehension of pathophysiology of this association and a possible role of cytokines such as IL-6 and antilymphoma therapies such as nivolumab or ASCT to MGUS development could represent an interesting research field that requires further investigations.
