Abstract
The past two decades have seen remarkable progress in both biological understanding and optimizing treatment of follicular lymphoma. Historically considered an incurable disease, long-term follow-up of several induction approaches demonstrates that up to 40% of patients enjoy remission durations of 10 or more years, and risk of dying of lymphoma continues to fall. This update will focus on progress in follicular lymphoma over the past 3 years, which has included refinements in staging and prognosis, novel immunotherapy treatment approaches for relapsed and refractory disease, and long-term follow-up of pivotal trials. Ongoing trials will define the optimal sequence for these novel treatments, including whether earlier incorporation of these approaches may result in definitive cure of this disease. Through ongoing and planned correlative studies, we are poised to ultimately achieve the goal of a precision management approach to follicular lymphoma.

Vinod N, Kim JH, Choi S, Lim I. Combination of 131I-trastuzumab and lanatoside C enhanced therapeutic efficacy in HER2 positive tumor model. Sci Rep 2021; 11:12871. [PMID: 34145369 PMCID: PMC8213814 DOI: 10.1038/s41598-021-92460-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2020] [Accepted: 06/03/2021] [Indexed: 12/03/2022] Open
Abstract
Lanatoside C has a promising anti-tumor activity and is a potential candidate for radiosensitizers. In this study, we have investigated the therapeutic efficacy of the combination of 131I-trastuzumab and lanatoside C for inhibition of human epidermal growth factor receptor 2 (HER2) positive tumor progression in NCI-N87 xenograft model. The combination treatment (131I-trastuzumab and lanatoside C) showed highest cytotoxicity when compared to non-treated control or trastuzumab alone or 131I alone or 131I-trastuzumab alone in vitro. Biodistribution studies using 131I-trastuzumab or combination of 131I-trastuzumab and lanatoside C showed tumor uptake in BALB/c nude mice bearing HER2 positive NCI-N87 tumor xenograft model. The higher tumor uptake was observed in 131I-trastuzumab (19.40 ± 0.04% ID/g) than in the combination of 131I-trastuzumab and lanatoside C (14.02 ± 0.02% ID/g) at 24 h post-injection. Most importantly, an antitumor effect was observed in mice that received the combination of 131I-trastuzumab and lanatoside C (p = 0.009) when compared to control. In addition, mice received lanatoside C alone (p = 0.085) or 131I-trastuzumab alone (p = 0.160) did not significantly inhibit tumor progression compared with control. Taken together, our data suggest that combination of 131I-trastuzumab and lanatoside C might be a potential synergistic treatment for radioimmunotherapy to control the HER2 positive tumor.

Venetoclax Synergizes with Radiotherapy for Treatment of B-cell Lymphomas. Cancer Res 2017; 77:3885-3893. [PMID: 28566329 DOI: 10.1158/0008-5472.can-17-0082] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2017] [Revised: 03/30/2017] [Accepted: 05/23/2017] [Indexed: 01/08/2023]
Abstract
Constitutive B-cell receptor signaling leads to overexpression of the antiapoptotic BCL-2 protein and is implicated in the pathogenesis of many types of B-cell non-Hodgkin lymphoma (B-NHL). The BCL-2 small-molecule inhibitor venetoclax shows promising clinical response rates in several lymphomas, but is not curative as monotherapy. Radiotherapy is a rational candidate for combining with BCL-2 inhibition, as DNA damage caused by radiotherapy increases the activity of pro-apoptotic BCL-2 pathway proteins, and lymphomas are exquisitely sensitive to radiation. We tested B-NHL responses to venetoclax combined with either external beam radiotherapy or radioimmunotherapy (RIT), which joins the selectivity of antibody targeting with the effectiveness of irradiation. We first tested cytotoxicity of cesium-137 irradiation plus venetoclax in 14 B-NHL cell lines representing five lymphoma subtypes. Combination treatment synergistically increased cell death in 10 of 14 lines. Lack of synergy was predicted by resistance to single-agent venetoclax and high BCL-XL expression. We then assessed the efficacy of external beam radiotherapy plus venetoclax in murine xenograft models of mantle cell (MCL), germinal-center diffuse large B-cell (GCB-DLBCL), and activated B-cell (ABC-DLBCL) lymphomas. In each model, external beam radiotherapy plus venetoclax synergistically increased mouse survival time, curing up to 10%. We finally combined venetoclax treatment of MCL and ABC-DLBCL xenografts with a pretargeted RIT (PRIT) system directed against the CD20 antigen. Optimal dosing of PRIT plus venetoclax cured 100% of mice with no detectable toxicity. Venetoclax combined with radiotherapy may be a promising treatment for a wide range of lymphomas Cancer Res; 77(14); 3885-93. ©2017 AACR.

England CG, Rui L, Cai W. Lymphoma: current status of clinical and preclinical imaging with radiolabeled antibodies. Eur J Nucl Med Mol Imaging 2016; 44:517-532.

Abstract
Lymphoma is a complex disease that arises from cells of the immune system with an intricate pathology. While lymphoma may be classified as Hodgkin or non-Hodgkin, each type of tumor is genetically and phenotypically different and highly invasive tissue biopsies are the only method to investigate these differences. Noninvasive imaging strategies, such as immunoPET, can provide a vital insight into disease staging, monitoring treatment response in patients, and dose planning in radioimmunotherapy. ImmunoPET imaging with radiolabeled antibody-based tracers may also assist physicians in optimizing treatment strategies and enhancing patient stratification. Currently, there are two common biomarkers for molecular imaging of lymphoma, CD20 and CD30, both of which have been considered for investigation in preclinical imaging studies. In this review, we examine the current status of both preclinical and clinical imaging of lymphoma using radiolabeled antibodies. Additionally, we briefly investigate the role of radiolabeled antibodies in lymphoma therapy. As radiolabeled antibodies play critical roles in both imaging and therapy of lymphoma, the development of novel antibodies and the discovery of new biomarkers may greatly affect lymphoma imaging and therapy in the future.
