124例原发胃恶性淋巴瘤患者的临床特征及预后分析
目的探讨原发胃淋巴瘤(PGL)的临床特征、治疗方法及预后。方法以2009年7月至2016年1月收治的124例PGL患者为研究对象,回顾性分析患者的临床资料,并探讨患者初诊时临床特征与预后的关系。结果124例PGL患者中包括弥漫大B细胞淋巴瘤(DLBCL)93例、黏膜相关淋巴组织(MALT)淋巴瘤25例、外周T细胞淋巴瘤非特指型4例、套细胞淋巴瘤和结外NK/T细胞淋巴瘤各1例。93例原发胃DLBCL(PG-DLBCL)患者中,非生发中心型(non-GCB)48例,生发中心型(GCB)45例,其中10例(10.8%)为MALT淋巴瘤转化的DLBCL。胃幽门螺杆菌检测:DLBCL患者阳性率51.2%...

Summary: | 目的探讨原发胃淋巴瘤(PGL)的临床特征、治疗方法及预后。方法以2009年7月至2016年1月收治的124例PGL患者为研究对象,回顾性分析患者的临床资料,并探讨患者初诊时临床特征与预后的关系。结果124例PGL患者中包括弥漫大B细胞淋巴瘤(DLBCL)93例、黏膜相关淋巴组织(MALT)淋巴瘤25例、外周T细胞淋巴瘤非特指型4例、套细胞淋巴瘤和结外NK/T细胞淋巴瘤各1例。93例原发胃DLBCL(PG-DLBCL)患者中,非生发中心型(non-GCB)48例,生发中心型(GCB)45例,其中10例(10.8%)为MALT淋巴瘤转化的DLBCL。胃幽门螺杆菌检测:DLBCL患者阳性率51.2%(21/41),MALT淋巴瘤患者阳性率43.5%(10/23)。单因素分析结果显示临床分期Ⅲ~Ⅳ期(P=0.002)、B症状(P=0.001)、高国际预后指数(P〈0.001)、HGB〈100 g/L(P〈0.001)、白蛋白〈35 g/L(P=0.001)、LDH升高(P〈0.001)、β2微球蛋白升高(P=0.003)、未联合利妥昔单抗(P=0.006)是影响PG-DLBCL患者无进展生存(PFS)的不良因素。多因素分析结果显示临床分期Ⅲ~Ⅳ期(HR=5.113,95%CI 1.087~24.048,P=0.039)、LDH升高(HR=5.111,95%CI 1.651~15.827,P=0.005)是影响患者PFS的独立危险因素。在PG-DLBCL non-GCB型组,是否接受利妥昔单抗治疗对患者PFS率的影响差异有统计学意义(P=0.013)。MALT淋巴瘤转化与非转化的DLBCL患者PFS率差异无统计学意义(P=0.373)。结论PGL以DLBCL和MALT淋巴瘤多见,PG-DLBCL是一组高度异质性的恶性肿瘤,临床分期Ⅲ~Ⅳ期和LDH升高是影响PG-DLBCL患者PFS的独立危险因素。 |

Bibliography: | ObjectiveTo analyze the clinical characteristics, treatment and prognosis of primary gastric lymphomas (PGL).MethodsA retrospective study was conducted in 124 cases of PGL from July 2009 to January 2016 in our hospital, and the clinical records, pathological and immunohistochemical features were analyzed. The relationship between different factors at diagnosis and prognosis were studied.Results124 cases of PGL included 93 diffuse large B cell lymphoma (DLBCL) patients, 25 mucosa associated lymphoid tissue (MALT) lymphoma cases, 1 mantle cell lymphoma, 4 peripheral T-cell lymphoma-not otherwise specified, and 1 extra-nodal NK/T-cell lymphoma-nasal type. Of the 93 primary gastric DLBCL (PG-DLBCL) patients, the germinal center B cell-like (GCB) DLBCL were 45 cases, non-GCB DLBCL were 48 cases. 10 cases (10.8%) of 93 PG-DLBCL were transformed from gastric MALT, and 7 cases (7.5%) have bone marrow involvement. Evidence of Helicobacter pylori infection was detected in 21 cases (51.2%) of 41 DLBCL patients and in 10 |
