摘 要:目的探讨中国人淋巴母细胞淋巴瘤/白血病(LBL)临床病理学特征、临床生物学行为及预后相关因素。方法收集确诊的LBL病例105例,应用HE、免疫组织化学(EnVision二步法),观察临床病理学及免疫表型特点。结果105例LBL患者,男女比例67:38。发病年龄0~73岁,中位年龄13岁。以淋巴结发病常见(53/105,50.48%),其中颈部淋巴结最为常见(34/53,64.15%);结外以纵隔最为多见(12/52,23.08%);69例(69/105,65.71%)出现骨髓累及,15例表现为首发症状。肿瘤细胞表达Ki-67(阳性率5%~90%);TdT、CD99、CD3E、CD20、CD79、PAX5、MPO、CD34及CD117的阳性率分别为84.76%(89/105)、85.00%(68/80)、5437%(56/103)、16.67%(16/96)、40.00%(8/20)、46.67%(28/60)、14.29%(8/56)、25.00%(4/16)及0。根据肿瘤细胞免疫表型标记结果将所有病例分为T细胞型62例(59.05%,62/105),B细胞型33例(31.43%,33/105),非T非B9例(8.57%,9/105),1例(0.95%,1/105)同时表达T、B淋巴细胞标志物。61例检测髓系标志物,8例(13.11%,8/61)有不同程度的表达,其中T细胞型4例、B细胞型4例。105例获随访资料,中位生存期36个月,1、2及3年生存率分别为66.67%(70/105)、48.81%(41/84)及20.69%(12/58)。免疫表型、骨髓侵犯以及骨髓移植与预后无明显相关性(P〉0.05)。年龄与预后明显相关,儿童和青少年预后明显好于成年人(P=0.032)。结论中国人LBL多发于儿童和青少年,男性多见,临床主要表现为多发淋巴结肿大,骨髓累及常见。临床生物学行为为侵袭性,年龄与临床预后相关,儿童和青少年预后明显好于成年人。Objective To study the clinicopathologic features and prognosis factor of Chinese lymphoblastic lymphoma. Methods 105 LBL cases were collected. Routine HE staining, immunostaining were used to investigate the clinieopathologic features, immunotype. Results The ratio of male to female was 1.76:1 (67:38), the medial age was 13 years old (0-73 years old). 53 cases (53/105, 50.48 %) primarily showed lymph node involvement, including 34 cases (34/53, 64.15 %) showed jugular node involvement; mediastinum (12/52, 23.08 %) was the most frequent extranodal involvement site. 69 cases (69/105, 65.71%) showed bone marrow involvement with 15 cases as the primary involvement. The expression of TdT, CD~, CD3~, CD20, CD79~, PAX5, MPO, CD34 and CDu7 was 84.76 % (89/105), 85.00 % (68/80), 54.37 % (56/103), 16.67 % (16/96), 40.00 % (8/20), 46.67 % (28/60), 14.29 % (8/56), 25.00 % (4/16) and 0. All cases were divided in to two groups, 62 cases as T-LBL (59.05 %, 62/105) and 33 cases as B-LBL (31.43 %, 33/105), with 9 cases (8.57 %, 9/105) without the expression of T or B cell marker and 1 cases with the expression of both T and B cell marker. 61 cases were detected the expression of myeloid markers and 8 cases were positive. All cases were followed up. The medial survival was 36 months. The survival at 1 year, 2 year and 3 year was 66.67 % (70/105), 48.81% (41/84) and 20.69 % (12/58) respectively. Age was the prognosis associated factor. The children had better progonosis than adults. Immunotype, bone marrow involovement and transplantation didn" t show prognosis indicator (P 〉 0.05). Conclusion Most of Chinese LBL occurs in child and younger male, multi-lymphadehypertrophy and bone marrow involvement are common. LBL is an aggressive tumor. Age is the prognosis associated factor. Children have a better prognosis than the adult.
