Extranodal natural killer/T‐cell lymphoma, nasal type, (ENKTL) is a rare distinct entity of non‐Hodgkin lymphoma. It is prevalent in Asia and Latin America but rare in North America and Europe. ENKTL represents an aggressive clinical course and a poor prognosis especially for advanced disease. There is no standard chemotherapeutic regimen for ENKTL. Recently, the efficacy of l ‐asparaginase in ENKTL has been confirmed. A series of l ‐asparaginase‐containing chemotherapeutic regimens have been studied in clinical trials and have significantly improved the efficacy and prognosis for patients with ENKTL. This review will focus on pharmacology of l ‐asparaginase, the efficacy of a series of l ‐asparaginase‐containing regimens in the treatment of ENKTL and future clinical study directions of l ‐asparaginase‐containing regimens in ENKTL.

目的 探讨早期结外鼻型NK/T细胞淋巴瘤(ENKTL)接受GELOX (吉西他滨、奥沙利铂、左旋门冬酰胺酶)方案化疗和放疗疗效及影响因素。方法 回顾分析2007—2013年间收治的74例ⅠE—ⅡE期ENKTL患者,根据化疗方案及有无放疗分为3个组,A组47例为首选GELOX化疗后根治性放疗,B组10例为其他方案化疗改用GELOX挽救后放疗,C组17例为接受GELOX方案化疗后未放疗。全组化疗中位3周期,放疗中位剂量54.6 Gy分20~30次。结果 全组化疗后CR率33.8%(其中放疗后为90%),2年OS和PFS分别为88%和79%。A+C组的疗后CR率、2年OS和PFS分别为73%、92%和84%。A组的2年OS和PFS (96%和84%)均高于B组(50%和45%)和C组(47%和40%,P均<0.05)。单因素分析显示疗前LDH水平升高和化疗后无缓解是OS和PFS的不良预后因素,局部广泛侵犯也是OS的不良预后因素;多因素分析显示化疗后无缓解是OS及PFS的不良预后因素。结论 早期ENKTL患者接受GELOX诱导化疗结合根治性放疗可获得良好疗效,但该方案用于单纯化疗和挽救化疗的疗效仍不理想。 相似文献

Survivin p53蛋白在鼻NK/T淋巴瘤中的表达及其与细胞凋亡和预后的关系 总被引:1,自引:0,他引:1
目的:探讨Survivin、p53蛋白在鼻NK/T淋巴瘤中的表达及其与细胞凋亡和预后的关系。方法:应用TdT介导的dUTP缺口末端标记(TUNEL)技术和免疫组织化学链霉菌抗生物素蛋白-过氧化酶连接法(SP法),检测24例鼻NK/T淋巴瘤和17例良性淋巴结病变中细胞凋亡和Survivin、p53蛋白的表达水平。结果:Survivin、p53蛋白在鼻NK/T淋巴瘤表达的阳性率分别为45.8%(11/24)和62.5%(15/24);Survivin表达上调与p53高表达密切相关(P<0.05);凋亡指数与Survivin、p53蛋白明显呈负相关(P<0.005)。Survivin过表达者的平均生存时间明显短于阴性者(P=0.03),但p53表达和细胞凋亡指数与患者的预后无相关性(P>0.05)。结论:Survivin基因异常表达引起的凋亡抑制可能在鼻NK/T淋巴瘤的发生进展中有一定的作用,且与p53异常表达显著相关。Survivin表达可能是鼻NK/T淋巴瘤的一个新的预后不良因子。 相似文献

Extranodal natural killer/T‐cell lymphomas (NK/TL), rare in Europe, are Epstein‐Barr virus (EBV) associated lymphomas with poor outcomes. Here, we determined the virus type and analyzed the EBV latent membrane protein‐1 (LMP1) gene sequence in NK/TL from French patients. Six clones of viral LMP1 were sequenced by Sanger technology in blood from 13 patients before treatment with an l ‐asparaginase based regimen and, for 8 of them, throughout the treatment. Blood LMP1 sequences from 21 patients without any known malignancy were tested as controls. EBV Type A was identified for 11/13 patients and for all controls. Before treatment, a clonal LMP1 gene containing a 30 bp deletion (del30) was found in 46.1% of NK/TL and only in 4.8% of controls. Treatment was less effective in these patients who died more rapidly than the others. Patients with a deleted strain evolving toward a wild‐type strain during treatment reached complete remission. The LMP1 gene was sequenced by highly sensitive next‐generation sequencing technology in five NK/TL nasopharyngeal biopsies, two of them originating from the previous patients. Del30 was present in 100% of the biopsies; two viruses at least coexisted in three biopsies. These results suggest that del30 may be associated with poor prognosis NK/TL and that strain evolution could be used as a potential marker to monitor treatment. 相似文献

Two cases of natural killer (NK)/T‐cell primary nasal lymphoma with similar clinical presentations are reported, for comparison and contrast, to highlight the clinical issues and challenges posed by this unusual disease, its aggressiveness being matched only by its rarity. Presenting as a lesion in the nasal cavity with histological features of malignant lymphoma, primary nasal lymphoma is an uncommon extranodal lymphoma, which poses problems in both diagnosis and management. In people of oriental descent, the common cell subtype is NK/T‐cell. Although it is generally thought that combination treatment with chemotherapy and radiation is the best management for early stage non‐Hodgkin's lymphoma (NHL), there is still debate as to whether combined therapy is optimal treatment for this particular subtype of NHL, given that it responds less well to conventional chemotherapy. Herein we report two patients to illustrate these controversies. 相似文献

Circulating Epstein-Barr virus (EBV) DNA is a biomarker of EBV-associated malignancies. Its prognostic value in early stage NK/T-cell lymphoma (NKTCL) in the era of asparaginase was investigated. 68 patients were treated with a median of 4 cycles of asparaginase-based chemotherapy followed by a median of 54.6Gy (range 50–60Gy) radiation. The amount of EBV-DNA was prospectively measured in both pretreatment and post-treatment plasma samples by real-time quantitative PCR. At the end of treatment, complete response (CR) rate was 79.4%, and overall response rate (ORR) was 88.2%. Patients with negative pretreatment EBV-DNA had a higher CR rate (96.0% vs. 69.8%, p = 0.023). The 3-year progression-free survival (PFS) rate and overall survival (OS) rate was 71% and 83%, respectively. In multivariate survival analysis, post-treatment EBV-DNA positivity and treatment response (non-CR) were prognostic factors for both worse PFS and OS (p < 0.05). Local tumor invasion was also a prognostic factor for worse OS (p = 0.010). In patients with CR, post-treatment EBV-DNA positivity correlated with inferior PFS and OS (both p < 0.0001). In patients with positive pretreatment EBV-DNA, negative post-treatment EBV-DNA correlated with better PFS and OS (both p < 0.0001). These findings indicate that post-treatment EBV-DNA positivity can predict early relapse and poor prognosis for patients with early stage NKTCL in the era of asparaginase, and may be used as an indicator of minimal residual disease. 相似文献

Peripheral T‐ or natural killer (NK)‐cell lymphomas are rare and difficult‐to‐recognize diseases. It remains arduous to distinguish between NK cell‐ and cytotoxic T‐lymphocyte‐derived lymphomas through routine histological evaluation. To clarify the cells of origin, we focused on NK‐cell receptors and examined the expression using immunohistochemistry in 22 cases with T‐ and NK‐cell neoplasms comprising angioimmunoblastic T‐cell lymphoma, anaplastic lymphoma kinase (ALK)‐positive and ‐negative anaplastic large‐cell lymphomas, extranodal NK/T‐cell lymphoma, nasal type, monomorphic epitheliotropic intestinal T‐cell lymphoma, aggressive NK‐cell leukemia, and other peripheral T‐cell lymphomas. Inhibitory receptor leukocyte immunoglobulin‐like receptor subfamily B member 1 (LILRB1) was detected in 14 (64%) cases, whereas activating receptors DNAM1, NKp46, and NKG2D were expressed in 7 (32%), 9 (41%), and 5 (23%) cases, respectively. Although LILRB1 was detected regardless of the disease entity, the activating NK‐cell receptors were expressed predominantly in TIA‐1‐positive neoplasms (DNAM1, 49%; NKp46, 69%; and NKG2D, 38%). In addition, NKp46 and NKG2D were detected only in NK‐cell neoplasms and cytotoxic T‐lymphocyte‐derived lymphomas including monomorphic epitheliotropic intestinal T‐cell lymphoma. One Epstein‐Barr virus‐harboring cytotoxic T‐lymphocyte‐derived lymphoma mimicking extranodal NK/T‐cell lymphoma, nasal type lacked these NK‐cell receptors, indicating different cell origin from NK and innate‐like T cells. Furthermore, NKG2D expression showed a negative impact on survival among the 22 examined cases, which mainly received the standard chemotherapy regimen (log‐rank test, P = .024). We propose that the presence of activating NK‐cell receptors may provide new insights into understanding peripheral T‐cell lymphomas and characterizing them as innate‐like T‐cell neoplasm. 相似文献

Extranodal natural killer (NK)/T‐cell lymphoma, nasal type (ENKTL) is an extranodal aggressive T or NK‐cell lymphoma that is characteristically associated with Epstein‐Barr virus (EBV) infection and cytotoxic tissue‐destructive features. Although ENKTL is described as a distinct entity according to the 2008 WHO classification, a considerable complexity is associated with the differential diagnosis of other T‐cell lymphomas with respect to tumour cell origins, locations, and the presence of EBV infection, as well as molecular and cytogenetic abnormalities. Here, we report a rare case of EBV‐negative ENKTL, where the absence of EBV in the true NK‐lineage cells was confirmed by extensive phenotypic and genotypic analyses. Furthermore, using the next‐generation sequencing approach, we identified mutations in the tumour suppressor genes KDM6A and TP53. The clinicopathological characteristics were almost similar to those of EBV‐positive ENKTL, except for the absence of EBV and histologically apparent angioinvasiveness. This is the first reported ENKTL case with mutations in the KDM6A gene. KDM6A is one of the histone‐modifying genes that are mutated in many human diseases including haematological cancers. Epigenetic regulation of gene expression has recently been demonstrated in ENKTL, and a similar pathway is thought to play an oncogenic role in EBV‐negative ENKTL. Our report shows the extent of comprehensive examination required before making a definitive diagnosis for NK‐ and T‐cell neoplasms and broadens the therapeutic options for potential targets. 相似文献
