2 International Variation Females

3 发病率 (Incidence)  亚洲国家的发病率较西方国家高,在非霍奇金淋巴瘤中的比例 15-20%  一项国际性回顾研究评估了北美、欧洲和亚洲 22 个地区 1314 例 T 细胞淋巴瘤 * * Arimitage.International Peripheral T-Cell and Natural Killer/T-Cell Lymphoma Study: Pathology Findings and Clinical Outcomes. J Clin Onco2008; 26(25):

4 International PTCL Study Major NHL Types by Region PercentNAEUAsia PTCL, unspecified Angioimmunoblastic Anaplastic, ALK Anaplastic, ALK NK/T-cell ATLL

5 Trends in incidence of PTCL by subtype from 1992 to 2005, 13 SEER registries PTCL incidence increased by 280%. Abouyabis et al., Leuk & Lymphoma 2008;49:2099

6 T-cell Lymphoma Classification: WHO Predominantly leukemic/disseminated T-cell prolymphocytic leukemia T-cell large granular lymphocytic NK/T-cell leukemia/lymphoma Adult T-cell leukemia/lymphoma Predominantly nodal Angioimmunoblastic T-cell lymphoma Anaplastic large cell lymphoma Peripheral T-cell lymphoma (Unspecified) Predominantly Extranodal Mycosis Fungoides Sezary syndrome Primary cutaneous CD30+ disorders Anaplastic large cell lymphoma Lymphomatoid papulosis Subcutaneous panniculitis-like T-cell NK/T-cell lymphoma-nasal Enteropathy-type intestinal lymphoma Hepatosplenic T-cell lymphoma Precursor T/NK Neoplasms Precursor T lymphoblastic leukemia/lymphoma Blastic NK lymphoma Peripheral T/NK Neoplasms

7 天津地区 20 年恶性淋巴瘤的发病率 天津医科大学肿瘤医院回顾性了分析 1986~2005 年天津地区 20 年恶性淋巴瘤的发病情况: 外周 T 细胞占非霍奇金淋巴瘤的比例高达 34% , 外周 T 细胞非特指型为 10.8% , NK/T 细胞淋巴瘤为 14.9% , 皮肤 T 细胞淋巴瘤为 2.0% , 肠病型 T 细胞淋巴瘤为 0.5% 。

8 Known Risk Factors Immune modulation –Congenital immunodeficiencies –Immunosuppression –HIV –Autoimmune disorders Infectious organisms –Human T-cell lymphotrophic virus (HTLV-1) - ATLL –Epstein-Barr virus (NK/T-cell, AITL?) –H Pylori Familial aggregation

29 Conclusions Single agent romidepsin is active in CTCL with an overall response rate (ORR) of 42% in evaluable patients including 6 CRs In advanced stage disease (IIB-IVA) the ORR is 48% –ORR in stage IIB 56%, SS 50% Pruritus relief in 63% of patients with mod-severe pruritus at baseline despite the exclusion of the use of steroids and antihistamines Most AEs associated with romidepsin were mild (grades 1-2) and manageable Romidepsin does not have a significant effect on the QT Interval
