[TCLF2015]解析T细胞淋巴瘤治疗进展和预后评价指标——Elaine S. Jaffe访谈
编者按:在TCLF 2015会议上,美国国家癌症研究所的Elaine S. Jaffe博士探讨了“WHO对外周T细胞淋巴瘤(PTCL)进行分类所考虑的因素”。报告结束后,Jaffe博士接受了《肿瘤瞭望》现场记者的采访。
照搬B细胞淋巴瘤治疗方案导致TCL治疗进展缓慢
过去T细胞淋巴瘤(TCL)的临床治疗照搬了B细胞淋巴瘤的方案(如美国CHOP方案和其他联合化疗方案)。因此很长时间以来没有研发出专门治疗TCL的方案。最近有很多研究人员设计出专门治疗TCL的方案,方案中纳入各种治疗TCL有效的新药。
Elaine S. Jaffe博士是美国国立癌症研究所癌症研究中心主任,在恶性淋巴瘤分型方面做了先驱性的研究,致力于促进临床医生和病理学家对淋巴瘤分型达成国际共识。研究重点是淋巴瘤的免疫学机制。
对TCL分子发病机制的了解促进治疗模式转变
在过去几年中,TCL的治疗慢慢进展,T细胞淋巴瘤的分子发病机制逐渐被理解。过去研究者只了解变性大细胞淋巴瘤(ALCL)和成人T细胞淋巴瘤(ATLL)的分子发病机制,最近几年对γδ T细胞淋巴瘤、血管免疫母细胞T细胞性淋巴瘤(AITL)也有了新见解,发现了肿瘤分子信号通路发生了哪些异常,并据此研发新的治疗药物。
PTCL的预后评价指标是肿瘤和肿瘤分期
有些研究团体已经发现一些PTCL的预后评价指标,似乎优于国际预后指数(IPI)。但是Jaffe博士认为主要预后评价指标应是淋巴瘤的亚型和分期,一些淋巴瘤大型试验研究结果就可以证明这一观点,比如一些T细胞恶性肿瘤(如晚期EBV阳性的NK细胞淋巴瘤)的侵袭性很强,因此肿瘤亚型和肿瘤分期是判断TCL预后的基础。

Oncology Frontier: Why peripheral T-cell lymphomas (PTCL) has lagged well behind other B-cell malignancies. Can you summarize the reasons for that?
《肿瘤瞭望》:外周T细胞淋巴瘤的治疗进展明显落后于B细胞淋巴瘤。您能总结一下原因吗?
Dr. Jaffe: I think traditionally the clinical practices for B-cell lymphomas were really just applied automatically to T-cell lymphomas, regimens such as CHOP in US and other combined chemotherapy regimens. So it takes a long time for more specialized treatment regimens to be developed for T-cell lymphomas. For many years they were lame together at the same clinical practices, now there’re many groups have regimens pacifically designed for T-cell lymphoma with the inclusion of drugs that are practically active in this group of tumors.

Oncology Frontier: What are the changing paradigms of treatment in PTCL from biology to clinical practice?
《肿瘤瞭望》:请您从生物学及临床实践角度阐述PTCL治疗模式的改变。
Dr. Jaffe: Again, just the treatment has been slowly to be developed for T-cell lymphomas, I think just the past few years we really are beginning to understand the molecular pathogenesis of many T-cell lymphomas. For many years, the only T-cell lymphoma with some understanding of molecular pathogenesis was anaplastic large cell lymphoma (ALCL) and Adult T-cell lymphoma (ATLL). Now just in the past few years, there are many new insights into cytotoxic T-cell malignancy, gamma-delta T-cell lymphoma, angioimmunoblastic T-cell lymphoma (AITL). So we are beginning to understand the pathway involved in the molecular pathogenesis of this tumor, and to develop new drugs.

Oncology Frontier: Can you list the factors predicting survival in peripheral T-cell lymphoma?
《肿瘤瞭望》:有哪些可预测PTCL治疗预后的指标?
Dr. Jaffe: Some groups have developed prognostic index that can be applied to T-cell lymphomas, and they seem to show some advantage over the standard IPI, I still think the main factors predicting prognosis and actual diagnosis was the subtype of lymphoma and the stage. We know some T-cell malignancies have very aggressive clinical course, such as EBV-positive?NK-cell is very clinically aggressive in the advanced stage, so I think when we look at the result of clinical trials, we really need to base on the actual diagnosis of T-cell lymphomas together.
Jaffe博士:有些研究团体已经发现一些PTCL的预后评价指标,似乎优于国际预后指数(international prognostic index, IPI)。但是我仍然认为预测预后的主要指标是淋巴瘤亚型和分期,从淋巴瘤大型试验研究结果我们就可以看出来。比如一些T细胞恶性肿瘤(如晚期EBV阳性的NK细胞淋巴瘤)侵袭性很强,因此判断TCL的预后要基于诊断。
