Abstract
Lymphoid malignancies typically promote an infiltrate of immune cells at sites involved by the disease. While some of the immune cells present in lymphoma have effector function, the immune system is unable to eradicate the malignant clone. Therapies that optimize immune function therefore have the potential to improve the outcome of lymphoma patients. In this Review, we discuss immunologic approaches that directly target the malignant cell as well as approaches to optimize both the innate and adaptive immune response to the tumor. While many of these therapies have shown single-agent activity, the future will clearly require thoughtful combinations of these approaches.

Lue JK, O'Connor OA. A perspective on improving the R-CHOP regimen: from Mega-CHOP to ROBUST R-CHOP, the PHOENIX is yet to rise. LANCET HAEMATOLOGY 2020; 7:e838-e850. [PMID: 33091357 DOI: 10.1016/s2352-3026(20)30222-2] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/31/2020] [Revised: 07/01/2020] [Accepted: 07/02/2020] [Indexed: 12/15/2022]
Abstract
The integration of rituximab (R) into cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) by Coiffier and colleagues was the first, and last, successful modification of this backbone regimen, which has endured now for almost 20 years. Countless attempts to redefine R-CHOP for patients with diffuse large B-cell lymphoma (DLBCL) have migrated from a focus on dose-intense and dose-dense regimens, to the use of maintenance therapies, and most recently the addition of novel agents. To date, none have changed the basic formula. Although there are many reasons for the absence of success, the incredible molecular heterogeneity of DLBCL is likely to be a major complicating factor. It is clear that as the scientific field's understanding of the genetic heterogeneity of DLBCL deepens, a precision medicine approach should be accounted for and might be one of several paths that could lead to improved outcomes. The rapid identification of poor prognostic groups within the evolving diverse molecular landscape of DLBCL will create new opportunities to produce the next generation of studies with targeted agents against specific pathological drivers. It is conceivable that targeting these driver pathways will require more than one agent, and of course, splitting the pool of patients with DLBCL into smaller groups on the basis of molecular characteristics, will reduce the number of eligible patients for clinical trial investigation. The integration of immunological agents might afford new opportunities to develop treatments agnostic to the complex molecular diversity, while adding minimal toxicity to the regimen. With each of these iterations, the hope is to ultimately shift away from a one-size-fits-all chemotherapy mentality to one predicated on an individualised approach, whether that be through the use of a targeted small molecule or a biological drug. In this Viewpoint, we explore the history of the collective efforts to improve upon R-CHOP, and underscore those lessons that might help to reshape our future plans.

Abstract
Primary cutaneous B-cell lymphomas are rare entities that develop primarily in the skin. They constitute a heterogeneous group that represents around a quarter of primary cutaneous lymphomas. The 2018 update of the World Health Organization-European Organization for Research and Treatment of Cancer (WHO-EORTC) classification differentiates primary cutaneous marginal zone lymphoma and primary cutaneous follicle center lymphoma with an indolent course from primary cutaneous diffuse large B-cell lymphoma, leg type with an aggressive behavior. The broad spectrum of clinical presentations and the disease course marked by frequent relapses are diagnostic and therapeutic challenges. The classification of these diseases has been refined in recent years, which allows to better define their immunopathogenesis and specific management. In the present article, we review the main clinico-biological characteristics and the current therapeutic options of these three main subsets. Based on the recent therapeutic advances in nodal B-cell lymphomas, we focus on the development of novel treatment options applicable to primary cutaneous B-cell lymphomas, including targeted therapies, combination treatments and immunotherapeutic approaches, and cover basic, translational and clinical aspects aiming to improve the treatment of cutaneous B-cell lymphomas.
