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.

 

  Jaffe博士:在过去几年中,TCL的治疗慢慢进展,而且逐渐开始理解对T细胞淋巴瘤的分子发病机制。过去只知道变性大细胞淋巴瘤(ALCL)和成人T细胞淋巴瘤(ATLL)的分子发病机制。最近几年对细胞毒性T细胞、γδ T细胞淋巴瘤、血管免疫母细胞T细胞淋巴瘤(AITL)也有了新见解,了解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。

 

  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。
