Abstract

PURPOSE

To analyze the association of genetic variation within the tumor necrosis factor (TNF -308 [G-->A]) and lymphotoxin alfa (LT-a +252 [A-->G]) genes with outcome in non-Hodgkin's lymphoma of childhood and adolescence.

PATIENTS AND METHODS

Genotyping of the TNF -308 (G-->A) and LT-a +252 (A-->G) polymorphisms in patients (n = 488) enrolled onto the German-Austrian-Swiss multicenter trial NHL-BFM 95 from April 1996 to January 2000 was performed by polymerase chain reaction with subsequent restriction fragment length polymorphism analysis on DNA from tumor-free specimen.

RESULTS

In patients with Burkitt's lymphoma (BL) and B-cell acute lymphoblastic leukemia (B-ALL; n = 219, 211 eligible patients), patients carrying at least two variant alleles (high-producer haplotypes) had an increased risk of events: probability of event-free survival (pEFS) at 3 years was 81% (SE = 5%), compared with 91% (SE = 2%) in low-producer haplotypes (P = .018). In BL/B-ALL with high tumor load (lactate dehydrogenase [LDH] > or = 500 U/L; n = 104), pEFS was 69% (SE = 8%) in high-producer versus 85% (SE = 4%) in low-producer haplotypes (P = .05). In multivariate analysis including risk factors for events (LDH > or = 500 U/L, CNS involvement, methotrexate infusion regimen), TNF -308/LT-alpha +252 haplotype kept prognostic relevance: patients with high-producer haplotypes had a 2.34-fold increase in risk of events (P = .048). The TNF -308 (G-->A) and LT-alpha +252 (A-->G) polymorphisms were not associated with pEFS in lymphoblastic lymphoma (n = 101), anaplastic large-cell lymphoma (n = 67), or diffuse large B-cell lymphoma (n = 65), nor with therapy-related toxicity.

CONCLUSION

The TNF -308 (G-->A) and LT-a +252 (A-->G) polymorphisms were negative prognostic factors in pediatric BL/B-ALL. Among patients with serum LDH > or = 500 U/L, haplotype analysis further determined patients at risk for events.

摘要

目的

分析肿瘤坏死因子(TNF -308 [G→A])和淋巴毒素α(LT-α +252 [A→G])基因内的遗传变异与儿童及青少年非霍奇金淋巴瘤预后的相关性。

患者与方法

对1996年4月至2000年1月参加德国 - 奥地利 - 瑞士多中心试验NHL - BFM 95的患者(n = 488)进行TNF -308(G→A)和LT-α +252(A→G)多态性基因分型,采用聚合酶链反应并随后对无肿瘤标本的DNA进行限制性片段长度多态性分析。

结果

在伯基特淋巴瘤(BL)和B细胞急性淋巴细胞白血病(B - ALL;n = 219,211例符合条件的患者)患者中,携带至少两个变异等位基因(高产单倍型)的患者发生事件的风险增加:3年无事件生存率(pEFS)为81%(SE = 5%),而低产单倍型患者为91%(SE = 2%)(P = 0.018)。在肿瘤负荷高(乳酸脱氢酶[LDH]≥500 U/L;n = 104)的BL/B - ALL中,高产单倍型患者的pEFS为69%(SE = 8%),低产单倍型患者为85%(SE = 4%)(P = 0.05)。在包括事件风险因素(LDH≥500 U/L、中枢神经系统受累、甲氨蝶呤输注方案)的多变量分析中,TNF -308/LT-α +252单倍型保持预后相关性:高产单倍型患者发生事件的风险增加2.34倍(P = 0.048)。TNF -308(G→A)和LT-α +252(A→G)多态性与淋巴细胞淋巴瘤(n = 101)、间变性大细胞淋巴瘤(n = 67)或弥漫性大B细胞淋巴瘤(n = 65)的pEFS无关,也与治疗相关毒性无关。

结论

TNF -308(G→A)和LT-α +252(A→G)多态性是儿童BL/B - ALL的不良预后因素。在血清LDH≥500 U/L的患者中,单倍型分析进一步确定了有事件风险的患者。
