Fifty-six patients with chemosensitive NHL were studied to assess factors affecting mobilization and peripheral blood stem cell (PBSC) collection: all were mobilized with high-dose cyclophosphamide and etoposide and G-CSF 5 microg/kg/day. None of them had bone marrow involvement at the time of mobilization or a history of extended field irradiation. Previous chemotherapy regimens were divided into two groups: moderately myelotoxic chemotherapy (MMC) and highly myelotoxic chemotherapy (HMC). The adequacy of the PBSC harvest was not associated with age, gender, a past history of bone marrow involvement or disease status. In contrast, the number of MMC cycles (n(MMC)) and the number of HMC cycles (n(HMC)) were both significant (P = 0.009 and P = 0.0004, respectively) and were used to compute a score predictive of a successful PBSC harvest: SCORE = n(MMC) + 4 n(HMC). The estimated successful PBSC collection rate was greater than 80% in patients with a score ranging from 0 to 15 and dropped rapidly to below 20% in patients with a score exceeding 25. This scoring system may help to determine the timing of PBSC mobilization in patients with a score below 15 and suggests that new PBSC mobilization procedures should be investigated in other patients.

对56例化疗敏感的非霍奇金淋巴瘤患者进行研究,以评估影响动员和外周血干细胞(PBSC)采集的因素:所有患者均采用大剂量环磷酰胺、依托泊苷及5μg/kg/天的粒细胞集落刺激因子(G-CSF)进行动员。动员时均无骨髓受累,也无扩大野照射史。既往化疗方案分为两组:中度骨髓毒性化疗(MMC)和高度骨髓毒性化疗(HMC)。PBSC采集的充足程度与年龄、性别、既往骨髓受累史或疾病状态无关。相反,MMC周期数(n(MMC))和HMC周期数(n(HMC))均具有显著意义(分别为P = 0.009和P = 0.0004),并用于计算预测PBSC采集成功的评分:评分 = n(MMC) + 4n(HMC)。评分在0至15分的患者中,估计的PBSC成功采集率大于80%,而评分超过25分的患者中,该成功率迅速降至20%以下。该评分系统可能有助于确定评分低于15分患者的PBSC动员时机,并提示应在其他患者中研究新的PBSC动员程序。《骨髓移植》(2000年)第25卷,第495 - 499页 。
