摘要: 背景 国内外研究已表明鞘氨醇-1-磷酸受体1(S1PR1)可作为多种疾病治疗的药物靶点。原发性睾丸弥漫大B细胞淋巴瘤(PT-DLBCL)为发病率较低的结外淋巴瘤,但侵袭能力强,应用现有的手段治疗后整体预后极差,亟须寻找新的治疗靶点。目的 了解S1PR1在PT-DLBCL病理组织中的表达情况,分析S1PR1的表达与PT-DLBCL预后的关系,探讨鞘氨醇-1-磷酸(S1P)/S1PR1作为该病治疗靶点的潜力。方法 收集1994年5月—2016年3月云南省肿瘤医院PT-DLBCL病理蜡块37例,随机选取普通结内弥漫大B细胞淋巴瘤(DLBCL)病理蜡块37例,通过免疫组化法比较S1PR1在PT-DLBCL和普通结内DLBCL组织中的表达差异。收集37例PT-DLBCL患者的临床资料,分析S1PR1的表达与患者预后的关系。结果 37例PT-DLBCL组织中,S1PR1表达阳性20例(54.1%)、阴性17例(45.8%)。37例普通结内DLBCL组织中,S1PR1表达阳性11例(29.7%)、阴性26例(70.3%)。PT-DLBCL组织中S1PR1阳性表达率高于普通结内DLBCL组织(χ2=4.497,P=0.034)。37例PT-DLBCL患者中,20例S1PR1阳性表达者中位总生存期(OS)为(21.9±4.6)个月、中位无进展生存期(PFS)为(10.1±2.3)个月,17例S1PR1阴性表达者中位OS为(71.9±9.6)个月、中位PFS为(64.6±10.9)个月。S1PR1阳性表达者3、5年总生存率(15.0%、10.0%)低于S1PR1阴性表达者3、5年总生存率(52.9%、35.3%)(χ2=10.971,P=0.001);S1PR1阳性表达者3、5年无进展生存率(5.0%、0)低于S1PR1阴性表达者3、5年无进展生存率(35.3%、23.5%)(χ2=15.833,P<0.001)。结论 S1PR1在PT-DLBCL中阳性表达率较普通结内DLBCL高,且其表达率高低与PT-DLBCL预后情况相关,S1P/S1PR1具有作为该病治疗靶点的潜力。

Abstract: Background  Studies have shown that sphingosine-1-phosphate receptor 1 (S1PR1) can be used as a drug target for the treatment of various diseases.Primary testicular diffuse large B-cell lymphoma (PT-DLBCL) is an extranodal lymphoma with a low incidence but a high degree of invasiveness.The overall prognosis is very poor after treating by existing therapies and it is urgent to find new therapeutic targets.Objective To explore the expression of S1PR1 in pathological tissue of PT-DLBCL,and analyze its relationship with the prognosis of PT-DLBCL,then to find out the potential of S1P/S1PR1 as a therapeutic target for this disease.Methods  From Yunnan Cancer Hospital,37 cases of PT-DLBCL and 37 cases of diffuse large B-cell lymphoma (DLBCL) were randomly recruited from May 1994 to March 2016.Immunohistochemistry was used to detect the expressional level of S1PR1 in paraffin wax block with the embedded PT-DLBCL and DLBCL tissues.Clinical data of PT-DLBCL cases were reviewed,and relationship of S1PR1 expressional level with the prognosis of PT-DLBCL was analyzed.Results  S1PR1 expression level was negative in 45.8%(n=17) of the PT-DLBCL cases,and in 70.3%(n=26) of the DLBCL cases.The prevalence of positive S1PR1 expression level was 54.1%(n=20) in the PT-DLBCL cases,and 29.7% (n=11) in the DLBCL cases,showing a significant difference(χ2=4.497,P=0.034).The median overall survival (OS) was (21.9±4.6) months and the median progression-free survival (PFS) was (10.1±2.3) months in 20 PT-DLBCL patients with S1PR1 positive expression,and in 17 PT-DLBCL patients with S1PR1 negative expression,the median OS was (71.9±9.6) months and the median PFS was (64.6±10.9)months.3 and 5 years OS rates(15.0% and 10.0%) in the positive expression of S1PR1 were lower than those in the negative expression of S1PR1 (52.9% and 35.3%)(χ2=10.971,P=0.001).3 and 5 years PFS rates(5.0% and 0) in the positive expression of S1PR1 were lower than those in the negative expression of S1PR1 (35.3% and 23.5%)(χ2=15.833,P<0.001).Conclusion The expression rate of S1PR1 in PT-DLBCL was higher than that in intranodal DLBCL,and its expression was related to the prognosis of PT-DLBCL.S1P/S1PR1 has the potential as a therapeutic target for the disease.
