摘要
目的探讨原发中枢神经系统弥漫大B细胞淋巴瘤(PCNS-DLBCL)患者的临床病理特征及预后情况。方法选择手术切除的PCNS-DLBCL组织30份,采用HE染色及En Vision二步法观察PCNS-DLBCL组织病理学特征和免疫表型特征;单因素分析患者发病年龄、国际预后指数(IPI)评分、体能状态(PS)评分、治疗方式、免疫表型与预后的关系,并采用COX回归模型对影响患者预后的因素进行多因素分析。结果 PCNS-DLBCL患者的临床表现以颅内压升高、局灶性神经功能缺损为主;形态学以中心母细胞型为主;免疫表型以non-GCB型为主。单因素分析显示,发病年龄、IPI评分、PS评分、治疗方式、免疫表型与患者预后有关(P均<0.05);多因素分析显示,IPI评分≥2分与预后相关(P<0.05)。结论 PCNS-DLBCL临床表现无特异性,患者长期生存率低,预后较差;IPI评分与患者预后有关。
Objective To investigate the clinical and pathological features of primary central nervous system diffuse large B-cell lymphoma( PCNS-DLBCL),and to investigate survival situation. Methods We got 30 cases of tissue specimen by surgical resection from PCNS-DLBCL patients,then observed pathological characteristics and immune phenotype by using En Vision two steps and HE staining. Univariate analysis was used to detect the relationships between prognosis and the features including age,PS score,IPI score,treatment and immune subtype. The Cox regression model analysis was used to analyze multivariate influence factors. Results The clinical manifestations were mainly intracranial high pressure and focal neurological deficits. Tumor cells mostly were centroblasts in morphology. The immune phenotype was mainly non-GCB type. Univariate analysis showed that the age,PS score,IPI score,treatment and immune subtype were statistically related to the prognosis of patients( all P < 0. 05). Multivariate analysis showed that IPI score which was more than 2was related to poor prognosis( P < 0. 05). Conclusions The clinical manifestations of PCNS-DLBCL were nonspecific,the long-term survival rate was low and the prognosis was poor. The IPI score was related to the prognosis of patients.
