目的 分析ⅠE~ⅡE期上呼吸消化道NK/T细胞淋巴瘤(UADT-NKTCL)经治疗后无瘤生存超过5年患者的远期复发率及危险因素。
方法 1983-2007年共114例ⅠE~ⅡE期UADT-NKTCL患者疗后5年内无瘤生存,其中32例单纯放疗、80例化放疗、2例单纯化疗。采用Kaplan-Meier方法计算复发率并Logrank检验及危险因素的单因素分析,Cox模型进行多因素分析。
结果随访率100%,随访时间满10年者79例。全组5年后复发12例(10.5%),复发中位时间8.2年(5.1~23.1年)。复发者中50%出现局部区域复发而无远处器官或淋巴结受累。全组10年肿瘤特异生存率和累积远期复发率分别为92.2%和8.4%。单因素分析显示初诊时有全身症状、ECOG评分≥2分、单纯化疗、初治时放疗剂量<50 Gy是远期复发因素(χ2=4.00~11.14,P=0.004~0.045),多因素分析显示初诊存在全身症状是远期复发危险因素[HR=4.74(95%CI=1.33~16.94),χ2=5.73,P=0.017]。
结论 早期UADT-NKTCL疗后5年内无瘤生存者仍有部分会出现复发。初诊时全身症状是UADT-NKTCL远期复发的独立危险因素。  相似文献

Allelotyping of gastrointestinal nasal-type NK/T-cell lymphoma   总被引:3,自引:0,他引:3  
Wan M  Chow J  Lei K  Chan W 《Leukemia research》2004,28(4):339-343
Nasal-type natural killer/T-cell lymphoma (NKL) is a rare but distinct malignancy that often involves the mid-facial region and the gastrointestinal tract. This study is the first genome-wide allelotyping analysis on this rare lymphoma. We applied 382 microsatellite markers covering loci which spanned 22 autosomes to screen for allelic imbalances (AI) in six intestinal NKL. The most common chromosomal regions of allelic imbalances were found in 11p, 9q and 13q. Novel spots of allelic losses spots found at 2p21, 2q37.22, 18p11.21 and 18q12.1. In spite of presence of a few recurrent loci of imbalances, the allelotyping results show that NKL is heterogeneous.  相似文献

The therapeutic outcome of chemotherapy in NK/T cell lymphoma (NTCL) has not been well documented until now. The aims of this study were to investigate the outcome of chemotherapy and to evaluate the clinical factors influencing the responsiveness to chemotherapy. Between 1995 and 2000, 59 patients received anthracycline-based chemotherapy as an initial treatment. Forty-five patients had nasal NTCL, whereas 14 had extranasal NTCL. Forty-one patients had stage I/II and 18 had stage III/IV disease. Epstein-Barr virus status was positive in 67.6% of cases. The results of initial chemotherapy were complete remission in 35.6% of the patients, 2-year disease-free survival in 22.9% and 2-year overall survival in 44.2%. Adjuvant radiotherapy after chemotherapy did not improve outcome in stage I/II nasal NTCL. The International Prognostic Index was a significant prognostic factor of complete remission rate, and stage was also significant for disease-free survival.  相似文献

Exosomal PD-L1 (exoPD-L1) is reported to be associated with immunosuppression in various cancers. However, its clinical value in extranodal NK/T cell lymphoma (ENKTL) has not been defined yet. We retrospectively evaluated the prognostic value of pretreatment circulating soluble PD-L1 (sPD-L1) and exosomal PD-L1 (exoPD-L1) in ENKTL patients treated with VIPD-containing chemotherapy. A total of 107 ENKTL patients, including 101 early stage and 6 advanced stage patients were enrolled in our study. ExoPD-L1 and sPD-L1 in the blood were measured by single molecule array (Simoa) and enzyme-linked immunosorbent assay (ELISA), respectively. Compared with the healthy individuals (n=16), the patients with ENKTL (n=107) exhibited significantly elevated exoPD-L1 and sPD-L1 levels in the blood. High pretreatment plasma exoPD-L1 concentration was associated with higher SUVmax level and recurrence rate. Similarly, high sPD-L1 group was also associated with some adverse clinical parameters, including advanced stage, elevated LDH levels, B symptoms, high IPI score and PINK score. The 5-year progression-free survival (PFS) rate and overall survival (OS) rates were 65.2% and 85.7% for the whole cohort, respectively. Patients with a low pretreatment exoPD-L1 level (simoa signal < 1.2) had 5-year OS and PFS rates of 88.1% and 86.1%, respectively, compared with 56.0%. (P=0.012) and 35.7% (P=0.007) in patients with high exoPD-L1 level (simoa signal > 1.2). The 5-year OS and PFS rates for patients with low sPD-L1 group (< 219 pg/mL) was significantly higher than high sPD-L1 group (≥ 219 pg/mL) (OS, 91.3% vs. 55.5%, P < 0.001; PFS, 68.9% vs. 34.6%, P=0.003). However, no correlation was found between circulating exoPD-L1 and sPD-L1 levels. This is the first study to measure plasma exoPD-L1 level on the Quanterix Simoa platform. Our results proved that circulating exoPD-L1 and sPD-L1 levels were significantly elevated in ENKTL and might be potential biomarkers for predicting the survival outcomes of ENKTL patients.  相似文献

结外NK/T细胞淋巴瘤L-GEMOX方案治疗的临床观察   总被引:4,自引:0,他引:4  
目的:观察L-GEMOX方案对结外NK/T细胞淋巴瘤的近期疗效和安全性。方法:回顾性分析32例经病理形态学及免疫组化证实为结外NK/T细胞淋巴瘤患者,均接受L-GEMOX方案治疗,至少接受2个周期。32例患者接受4个周期化疗后行疗效评价,诱导化疗后行序贯累计野放疗。结果:32例结外NK/T细胞淋巴瘤患者中,诱导化疗后完全缓解(CR)率为53.1%(17/32),部分缓解(PR)率为31.3%(10/32),疾病稳定(SD)率为9.4%(3/32),疾病进展(PD)率为6.3%(2/32)。完成放射治疗后,CR率为62.5%(20/32), PR率37.5%(12/32),有效率为100%。临床特征分析显示原发部位、临床分期与患者近期疗效相关(P<0.05)。主要不良反应为骨髓抑制、黏膜炎、转氨酶升高及血糖波动等,多为轻中度,予对症处理或化疗停止后很快缓解。无治疗相关死亡。结论:培门冬酶及吉西他滨联合奥沙利铂( L-GEMOX)作为一线诱导化疗方案,对结外NK/T细胞淋巴瘤的近期疗效佳,不良反应轻,安全性好,是Ⅰ期、Ⅱ期鼻NK/T细胞淋巴瘤新的治疗选择。将来需进一步开展大样本的前瞻性研究,评估L-GEMOX方案能否改善结外NK/T 细胞淋巴瘤的总生存期和无病生存期。  相似文献

结外NK/T细胞淋巴瘤(extranodal NK/T-cell lymphoma,ENKTCL)是一种高度侵袭性的非霍奇金淋巴瘤,对以门冬酰胺酶为基础的化疗方案较敏感,但仍有部分患者预后不佳。近年来,随着对ENKTCL发病机制的进一步了解,认为免疫靶向治疗在初治或复发难治ENKTCL患者治疗中具有重要的临床价值。本文就单克隆抗体类药物、靶向细胞信号传导通路的小分子抑制剂、表观遗传学药物、免疫调节剂、EBV特异性细胞毒性T细胞及嵌合抗原受体修饰的T细胞治疗在ENKTCL中的临床前研究及临床试验等研究进展进行综述。  相似文献

PURPOSE: To investigate the role of early or up-front radiotherapy (RT), the optimal RT dose required to achieve appropriate treatment outcome and prognostic factors for patients with localized extranodal NK/T-cell lymphoma, nasal-type, in the upper aerodigestive tract. METHODS AND MATERIALS: Eighty-two patients were reviewed. Eight patients were treated with chemotherapy (CT) alone, 9 patients received RT alone, and 65 patients were given combined modality treatment of CT and RT (CMT). Of those 74 patients receiving RT, 31 patients were given up-front RT, whereas CT was the initial therapy for 43 patients and 41 of those 43 patients received early RT. RESULTS: Five-year overall survival (OS) and disease-free survival (DFS) were 52.3% and 39.2%, respectively. RT was the only independent prognostic factor for both OS and DFS at both the univariate and multivariate level. The 5-year OS and DFS were better in patients receiving >or=54 Gy of RT as compared with that of <54 Gy (5-year OS 75.5% vs. 46.1%, p = 0.019; 5-year DFS 60.3% vs. 33.4%, p = 0.004). Up-front RT presented better survival in Stage I patients when compared with that of initial CT followed by early RT (5-year OS 90.0% vs. 48.9%, p = 0.012; 5-year DFS 78.7% vs. 39.9%, p = 0.021). CONCLUSION: Early or up-front RT had an essential role in improved OS and DFS in patients with localized extranodal NK/T-cell lymphoma, nasal-type, in the upper aerodigestive tract. The recommended tumor dose was at least 54 Gy. Up-front RT may yield more benefits on survival in patients with Stage I disease.  相似文献

Background

Extranodal NK/T-cell lymphoma (ENKL) is an aggressive hematological malignancy associated with Epstein–Barr virus (EBV) infection. It is often resistant to conventional chemotherapy and has a poor prognosis. Icaritin, a compound derived from Chinese herbal medicine, Herba Epimedii, has been reported to exert antitumor effects on a variety of cancer cell lines. In the present study, we investigated the cytotoxic effects of Icaritin on the two EBV-positive ENKL cell lines SNK-10 and SNT-8, along with the underlying molecular mechanisms.

Methods

ENKL cell lines SNK-10 and SNT-8 were exposed to different concentrations of Icaritin for the indicated time. Treated cells were analyzed for cell proliferation, cell cycle, and cell apoptosis. Phosphorylation of Stat3 and Akt proteins in signaling pathways and the EBV-encoded LMP1 proteins were measured by Western blot. Expression of EBV genes was assessed by Real-Time PCR.

Results

Our results showed that Icaritin dose-dependently inhibits ENKL cell proliferation and induces apoptosis and cell cycle arrest at G2/M phase. Additionally, Icaritin upregulates Bax, downregulates Bcl-2 and pBad, and activates caspase-3 and caspase-9. The anti-proliferative and pro-apoptotic effects of Icaritin are likely mediated by inhibition of Stat3 and Akt pathways through LMP1 downregulation. Importantly, Icaritin induces EBV lytic gene expression in ENKL cells, and the combination of Icaritin and the antiviral drug ganciclovir (GCV) is more effective in inducing ENKL cells apoptosis than Icaritin or GCV alone.

Conclusions

These findings indicate that EBV-targeted approaches may have significant therapeutic potential for ENKL treatment.  相似文献
