203例慢性淋巴细胞白血病患者预后相关因素分析

Objective To explore prognostic factors in patients with chronic lymphocytic leukemia (CLL). Methods Two hundred and three CLL patients in our hospital between 2000 to 2007 were retro-spectively reviewed for prognostic factor analysis. Survival was analysed by Kaplan-Meier analysis, univariate analysis by Log-rank test and multivariate analysis by COX regression model. Results With a median follow-up time of 48.0 (3.0 - 156.0) months, the 5-year overall survival (OS) rate was (87.3 ± 2.4) % and 10-year OS rate was (77.4 ± 3.3) %. Forty-eight (23.6%) patients died. Univariate analysis indicated that ad-vanced clinical stage, B symptoms, extranodal involvement, number of lymph node regions involved ≥3, en-larged liver, Hb < 100 g/L, BPC < 100 × 109/L, absolute lymphocyte count (ALC) > 50 × 109/L, atypical cell morphology, progression to stage, non-respons to treatment, complicating infections and secondary cancer or disease transformation were associated with poor prognosis. And on multivariate analysis, lymph node re-gion involvod≥3 and atypical cell morphology were independent poor prognostic factors. Based on the two in-dependent poor prognostic factors, three risk groups were defined: low- (0 factor), intermediate-(one factor) and high-(two factors) groups. The 5 year OS rates were (89.8 ± 3.5) % , (66.4 ～ 7.2) % and (15.0 ±13.8)%, respectively, and the difference between them was statistically. Conclusion The number of lymph node region involved and cell morphology are useful for assessing CLL patients prognosis.

注射用重组人血清白蛋白-人粒细胞集落刺激因子(Ⅰ)融合蛋白在健康受试者的耐受性研究

目的评价重组(酵母分泌型)人血清白蛋白-人粒细胞集落刺激因子(Ⅰ)融合蛋白在健康受试者的耐受性和安全性。方法将26例健康受试者(男女各半)按先后顺序入组,进行4个剂量组试验(150,300,500,650μg·kg^-1),每组分别入组4,6,8,8例。根据体重计算给药剂量,受试者于给药当天上臂三角肌部位皮下注射给药1次。用药后观察药物不良事件(AE),定时进行实验室检查、心电图检查。结果共25例受试者发生AE,共145例次。150,300,500及650μg·kg^-1剂量组的AE分别为13,11,56和65例次。其中134例次考虑与研究药物相关。常见的AE有骨痛、单核细胞计数升高、血碱性磷酸酶升高、头痛、高尿酸血症、血乳酸脱氢酶升高、脾肿大、肌肉疲劳。研究中未出现AE导致的用药暂停、受试者退出或试验提前中止。未发生严重不良事件(SAE)。未发生剂量限制性毒性。结论注射用重组(酵母分泌型)人血清白蛋白-人粒细胞集落刺激因子(Ⅰ)融合蛋白在中国健康受试者中单次给药150,650μg·kg^-1剂量范围内有较好的安全性,本临床试验未探索到健康人群的最大耐受剂量。

43例淋巴母细胞淋巴瘤患者临床特点及疗效分析

Objective To investigate the clinical features and treatment outcomes of different regimens in Chinese patients with lymphoblastic lymphoma(LBL). Methods Forty-three patients with LBL were retrospectively analysed, of which 30 were T-LBL, and 13 B-LBL. Results ①Most patients were young men with a median age of 21, and 63.0％ of the T-LBL patients had mediastinal masses. ② Treatment outcome could be assessed in 37 cases, of which the response rate (RR) was 81.1％ and complete remission (CR) rate was 67.6％. The RR and CR rates in patients treated with regimens for ALL (ALL-like group) and those treated with regimens for NHL(NHL-like group) were 94.4％ , 68.4％ and 83.3％ , 52.6％ , respectively. ③The estimated median overal survival(OS) and progression free survival (PFS) of hematopoietic stem cell transplantation (HSCT) group were significant longer than those of ALL-like group(P =0.018, P=0.025) and NHL-like group(P = 0. 016, P = 0. 011). The OS at 5 years in NHL-like group, ALL-like group and HSCT group were (14.4 ± 9.4) ％ , (20.2 ± 12.7) ％ and (79.5 ± 13.1) ％, respectively. Conclusion ①LBL is more common in young men, with less involvement of peripheral blood. Compared with B-LBL, T-LBL often has a mediastinal mass and serious cavity effusion. ② Intensive treatment regimens for ALL should be used in LBL. HSCT at CR1 can improve outcome obviously.
