ESMO 2024

2024年欧洲肿瘤内科学会(ESMO)年会于近日在西班牙巴塞罗那盛大召开。作为肿瘤领域的国际顶级盛会之一,来自全球的专家学者齐聚一堂,共享前沿研究成果,共谋未来发展方向。在本次大会上,血液恶性肿瘤领域涌现出多项重磅研究,为当前临床诊疗和未来研究带来启示和参考。《肿瘤瞭望-血液时讯》现场特邀血液恶性肿瘤Mini oral专场的主席之一、意大利东皮埃蒙特大学Annarita Conconi教授点评这些重磅研究,并通过回顾血液肿瘤领域取得的重要进展,展望未来发展趋势。

在本次会议上,您参与多项研究的讨论(813MO、814MO、815MO、816MO),可否请您点评下这几项研究,以及它们对促进血液肿瘤领域的发展有哪些重要意义?

Annarita Conconi教授:在本次ESMO大会上,我参与讨论了4项涵盖不同主题的研究。第一项是关于一种新型疫苗与布鲁顿酪氨酸激酶(BTK)抑制剂联合治疗慢性淋巴细胞白血病(CLL)的I期临床试验(813MO),旨在提高该类患者的治疗缓解深度。BTK抑制剂是高危CLL患者治疗的基石,但单药治疗的完全缓解率较低。逆转在CLL中常见的T细胞功能障碍,可能有助于与疫苗疗法产生协同作用。


第二项研究涉及免疫豁免淋巴瘤的分子分析(814MO),揭示了对这些罕见实体的新发现,主要集中在结外淋巴瘤,特别是原发性乳腺弥漫性大B细胞淋巴瘤(DLBCL),为其正确分类和作为特定疾病实体的鉴定提供了新证据。

第三项研究是关于BTK抑制剂奥布替尼联合奥妥珠单抗治疗新诊断的边缘区B细胞淋巴瘤的II期临床试验(815MO),在临床活性方面显示出有趣的初步疗效。

第四项研究聚焦于克隆性造血与单克隆B细胞淋巴细胞增多症(MBL)两种血液学前体相结合的临床影响(816MO),以及随后的淋巴恶性肿瘤发展风险。

Oncology Frontier-Hematology Frontier:During this conference, you participated in the discussion of several studies (813MO, 814MO, 815MO, 816MO). Could you please provide your commentary on these studies and  elaborate on their significance in advancing the development of hematological malignancies?
Dr. Annarita Conconi:Yes, my task today was to discuss four different studies encompassing a wide range of different topics. The first was a Phase 1 clinical trial testing a new vaccine approach in combination with BTK inhibitors for the treatment of chronic lymphocytic leukemia (CLL). The goal is to improve the depth of response in this patient population, in which BTK inhibitors represent a cornerstone in the treatment of high-risk disease but have a low rate of complete remission as monotherapy. Reverting the T-cell function impairment often observed in CLL may be useful in producing a synergistic effect with the vaccine approach tested in the study presented. Other investigations refer to the molecular profiling of immunoprivileged lymphomas, with new observations concerning these rare entities, primarily extranodal lymphomas, providing new evidence for their proper classification and identification as specific disease entities. This includes, in particular, primary breast diffuse large B-cell lymphoma (DLBCL). The variety of subjects can also be seen in a Phase 2 clinical trial testing a combination of targeted therapy. Orelabrutinib a Bruton’s tyrosine kinase (BTK) inhibitor, combined with obinutuzumab in the treatment of newly diagnosed marginal zone B-cell lymphomas, has shown interesting but preliminary findings in terms of clinical activity. A large-scale investigation focused on the clinical impact of clonal hematopoiesis in combination with monoclonal B-cell lymphocytosis (MBL) and the risk of subsequent development of lymphoid malignancies.

您长期深耕于非霍奇金淋巴瘤领域的分子生物学研究和临床试验,请您谈谈目前在该方面有哪些重要进展,这些进展如何改变了患者的治疗结局和生存?

Annarita Conconi教授:在过去几十年中,血液恶性肿瘤治疗领域的最重要进展是靶向疗法和免疫疗法的引入,包括基于B细胞和T细胞的免疫疗法。这些疗法将改变我们治疗患者的方式,包括初治和复发/难治性患者,向更多的无化疗(chemo-free)治疗策略发展。

Oncology Frontier-Hematology Frontier: As a long-time researcher in the field of molecular biology and clinical trials for non-Hodgkin's lymphoma, could you please discuss the current significant advancements in this area and how these advancements have altered patients' treatment outcomes and survival?
Dr. Annarita Conconi: The most relevant advancements in the treatment of hematological malignancies observed during the last decades are the introduction of targeted therapies and immunotherapies, including both B and T-cell-based immunotherapies. This will change the perspective of treating our patients towards more frequent chemotherapy-free strategies. In both treatment-naive and relapsed/refractory disease.

随着分子生物学技术的快速发展,血液肿瘤已步入精准化诊疗时代。您认为在血液肿瘤的精准诊疗方面还面临哪些挑战,未来有哪些值得关注的研究方向?

Annarita Conconi教授:在过去几十年中,我们的研究重点是确定影响化疗耐受性和耐药性的变量和因素,这也是当前可用的主要治疗工具。但现在,我们正转向免疫疗法——基于T细胞和B细胞的免疫疗法。目前所有生物学研究都应集中在定义免疫耐药性上。我们必须明确影响患者对免疫疗法抗肿瘤活性耐药性的因素。

Oncology Frontier-Hematology Frontier:With the rapid development of molecular biology technologies, hematological malignancies has entered the era of precision medicine. What challenges do you believe the field still faces in achieving precision diagnosis and treatment for blood cancers? What research directions are worth paying attention to in the future?
Dr. Annarita Conconi:Over the last decades, our attention was focused on identifying variables and factors affecting chemo-resistance, which determine the resistance of patients to chemotherapy. The main tool available for their treatment. Now, we are moving towards immunotherapies—T-cell-based and B-cell-based immunotherapies. All biological investigations should now be oriented towards defining immune resistance. We must identify factors that can define patient resistance to the anti-tumor activity of immune-based therapies.
